Leonardo da Vinci is best remembered as the painter of the Mona Lisa (1503-1506) and The Last Supper (1495). But he's almost equally famous for his astonishing multiplicity of talents: he dabbled in architecture, sculpture, engineering, geology, hydraulics and the military arts, all with success, and in his spare time doodled parachutes and flying machines that resembled inventions of the 19th and 20th centuries. He made detailed drawings of human anatomy which are still highly regarded today. Leonardo also was quirky enough to write notebook entries in mirror (backwards) script, a trick which kept many of his observations from being widely known until decades after his death.

Leonardo da Vinci means "Leonardo from the town of Vinci," and thus he is generally referred to in short as "Leonardo" rather than as "da Vinci"... He received a fresh burst of public interest in 2003 with the publication of The Da Vinci Code, the bestselling thriller by author Dan Brown.

(born April 15, 1452, Anchiano, Republic of Florence — died May 2, 1519, Cloux, France) Italian Renaissance painter, sculptor, draftsman, architect, engineer, and scientist. The son of a landowner and a peasant, he received training in painting, sculpture, and mechanical arts as an apprentice to Andrea del Verrocchio. In 1482, having made a name for himself in Florence, he entered the service of the duke of Milan as "painter and engineer." In Milan his artistic and creative genius unfolded. About 1490 he began his project of writing treatises on the "science of painting," architecture, mechanics, and anatomy. His theories were based on the belief that the painter, with his powers of perception and ability to pictorialize his observations, was uniquely qualified to probe nature's secrets. His numerous surviving manuscripts are noted for being written in a backward script that requires a mirror to be read. In 1502 – 03, as military architect and engineer for Cesare Borgia, he helped lay the groundwork for modern cartography. After five years of painting and scientific study back in Florence (1503 – 08), he returned to Milan, where his scientific work flourished. In 1516, after an interlude under Medici patronage in Rome, he entered the service of Francis I of France; he never returned to Italy. Though only some 17 completed paintings survive, they are universally seen as masterpieces. The power of The Last Supper (1495 – 98) comes in part from its masterly composition. In the Mona Lisa (c. 1503 – 06) the features and symbolic overtones of the subject achieve a complete synthesis. The unique fame that Leonardo enjoyed in his lifetime and that, filtered by historical criticism, has remained undimmed to the present day rests largely on his unlimited desire for knowledge, a trait that guided all his thinking and behaviour.

[b. Vinci (Italy), April 15, 1452, d. Amboise, France, May 2, 1519]

Leonardo's great reputation in science and invention is posthumous, based on the translation and publication of his coded notebooks in the late 19th and early 20th centuries. In his lifetime, in addition to his famous paintings, he was known for his engineering of canal locks, cathedrals, and engines of war. The notebooks reveal Leonardo's correct interpretations of anatomy, explanations of physical concepts such as inertia, and sketches for working parachutes and helicopters, all well in advance of those ideas entering the scientific record.

(b Anchiano, nr Vinci, 15 April 1452; d Amboise, nr Tours, 2 May 1519). Italian painter, sculptor, architect, designer, theorist, engineer and scientist. He was the founding father of what is called the High Renaissance style and exercised an enormous influence on contemporary and later artists. His writings on art helped establish the ideals of representation and expression that were to dominate European academies for the next 400 years. The standards he set in figure draughtsmanship, handling of space, depiction of light and shade, representation of landscape, evocation of character and techniques of narrative radically transformed the range of art. A number of his inventions in architecture and in various fields of decoration entered the general currency of 16th-century design.

Leonardo da Vinci (1452-1519) Leonardo was renowned in his lifetime as a painter, sculptor, architect, musician, engineer, and cartographer, but the degree of awareness of his anatomical work among his contemporaries is a mystery. Almost everything that we know today about his researches is contained in 200 sheets of drawings and notes housed in the Royal Library at Windsor Castle.

As a young artist in Florence, Leonardo absorbed the prevailing theoretical interest in a quasi-scientific basis for painting. This included the study of superficial anatomy, through life drawing and attendance at the public dissections that were occasionally held by the medical schools. There is no evidence that he was interested in deep anatomy until the late 1480s, by which time he had moved to Milan. There he outlined a plan for a treatise on the human body, covering not only anatomy but also conception, growth, proportion, the emotions, and the senses. A number of sheets from around this date comprise syntheses of animal dissection, surface observation, and traditional beliefs, though Leonardo does not seem to have pursued his studies systematically. He reportedly compiled a manuscript treatise on the anatomy of the horse, now lost; his human material was primarily skeletal, most notably a series of highly accurate drawings of the skull, sectioned in an attempt to locate the sites of the mental faculties.

Due to other obligations, Leonardo's anatomical work ceased from about 1493 till around 1504, when in connection with the abortive Battle of Anghiari mural in Florence he systematically surveyed the superficial aspects of man. An interest in hydrodynamics soon led him back to a study of the deeper systems of the body, for he now had some access to corpses in the hospital of Santa Maria Nuova. In the winter of 1507-8, Leonardo was present at the peaceful demise of an elderly man, prompting him to perform an autopsy ‘to see the cause of so sweet a death’. The resulting drawings and notes include the first records of the appendix, cirrhosis of the liver, arteriosclerosis, calcification of vessels, and coronary vascular occlusion. He also returned briefly to an investigation of the structure of the brain, making a wax cast of an ox's ventricles.

Shortly afterwards Leonardo's interests changed fundamentally. A beautiful and highly accurate series of drawings, datable to the winter of 1510-11, concentrate on the mechanics of the osteological and myological systems. His methods of illustration were particularly inventive: the bones of the thorax drawn orthographically; the cervical vertebrae in an exploded view; the hand through six stages of dissection; the shoulder muscles reduced to lines of force to depict the whole system in a single drawing; the arm in seven views through 180 degrees; and so on.

This change in approach seems to have been due to a collaboration with Marcantonio della Torre, the young Galenist and professor of anatomy at the university of Pavia. Leonardo now had much greater access to human material: the number of dissections he claimed to have performed grows from ‘more than ten’ around 1509, to ‘more than thirty’ towards the end of his life. This was the only phase of his researches when he achieved a working compromise between coverage and detail, for it was still his intention to publish a treatise, and, after Marcantonio's death in 1511, Leonardo concentrated primarily on cardiology and embryology.

Leonardo dissected a fetus of about six months, studying the relative sizes of the viscera, though his understanding of the structure of the human placenta was coloured by observations made in an earlier dissection of a gravid cow. More rewarding was his work on the bovine heart. He identified the auricles and described the movements of diastole and systole; he constructed a glass model of the aortic valve and, observing the vortices in the sinuses, he correctly deduced the exact mechanism of closure of the valves. Leonardo was on the verge of discovering the circulation of the blood, but he could not abandon the ancient belief in the independence of the arterial and venous systems, and he modified his results to accommodate this.

In late 1513, Leonardo moved to Rome, where he conducted research in the Ospedale di Santo Spirito, though few resulting drawings can be identified. In 1515 he was accused before Pope Leo X of unspecified sacrilegious practices and was barred from the Ospedale. The following year he went to France, dying there without resuming his anatomical work, and without having completed the treatise that he had planned for thirty years. Leonardo's papers passed to a pupil, Francesco Melzi, at whose villa near Milan they were occasionally seen by visitors, but they were not widely known until the publication of a series of facsimiles around 1900.

The mystery of Leonardo da Vinci

Top

The place of Leonardo in history as an artist and even as a scientist is well known. Many of his inventions, such as the helicopter, were only on paper, however. His actual achievements and contributions to the technology of his time are less well known and somewhat problematical. On the one hand, it is said that none of his ideas were practical, while on the other, it is said that his improvements in canal locks have been imitated ever since.

After striking success as a painter in his youth, Leonardo, at about age 30, began to take commissions in fields that we would today identify as architecture or engineering. From then on, he made at least part of his living designing improvements on buildings and canals, some of which he then built and some of which languished. Increasingly he designed in secret devices that anticipated flight, steam power, and much more.

Much of the reason for the apparent mystery of his ideas about technology is that he wrote and drew them in coded notebooks that, although he worked on them for much of his adult life, were never sufficiently organized to decode and publish. Indeed, most pages of the notebooks were not published until late in the 19th century. All his life he found it difficult to complete a task, even abandoning paintings for which he had been paid. Single pages of the famous notebooks, although nearly all written so that each deals with a separate chain of thought, often slip from one topic to another.

Among the public achievements that contributed to the technology of his time are the maps of Italy he made at the beginning of the 16th century. Although none of his architectural plans were executed, many were known at the time and became a major influence on such buildings as St. Peter's in Rome. In addition to canal lock gates, replacements in 1497 for worn-out gates on the oldest canal in Italy, it is thought that he actually built a screw-cutting machine and a turret windmill, both advanced for the time and not followed by others until much later. Some give Leonardo partial credit (along with Palladio) for the truss bridge, but trusses were occasionally used by the Romans and did not become common in bridges until centuries after Leonardo's death.

It is thought that some may have seen his notebooks and been influenced, notably Girolamo Cardano, but that is not certain. If they had been, we might have earlier had the advantage of Leonardo's experiments with tensile strength, his analysis of forces produced by arches and hoisting devices, and his work on the strength of beams and columns. A half century after Leonardo's death, another great Italian, Galileo, repeated such experiments and analyses -- and published them in a clear, coherent form.

Leonardo da Vinci (1452-1519), Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans ‘for bridges, very light and strong’, and ‘plans for destroying those of the enemy’. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, ‘very convenient and easy of transport’, designed to fire ‘small stones, almost in the manner of hail’—grape- or case-shot (see ammunition, artillery). He offered cannon ‘of very beautiful and useful shapes, quite different from those in common use’ and, ‘where it is not possible to employ cannon … catapults, mangonels and trabocchi [trebuchets—see siege engines] and other engines of wonderful efficacy not in general use’. And he said he made ‘armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery … and behind them the infantry will be able to follow quite unharmed, and without any opposition’. He also offered to design ‘ships which can resist the fire of all the heaviest cannon, and powder and smoke’.

The large number of surviving drawings and notes on military art show that Leonardo's claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum—a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful.

Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: ‘dual use technology’.

Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi's works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his ‘Military Engineer General’, although no known building by Leonardo exists.

Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.

Leonardo da Vinci

Top

Leonardo da Vinci (1452-1519) was an Italian painter, sculptor, architect, engineer, and scientist. He was one of the greatest minds of the Italian Renaissance, and his influence on the painting of the following generations was enormous.

Leonardo da Vinci was born on April 15, 1452, near the village of Vinci about 25 miles west of Florence. He was the illegitimate son of Ser Piero da Vinci, a prominent notary of Florence, who had no other children until much later. Ser Piero raised his son himself, a common practice at the time, arranging for Leonardo's mother to marry a villager. When Leonardo was 15, his father apprenticed him to Andrea del Verrocchio, the leading artist of Florence and a characteristic talent of the early Renaissance.

Verrocchio, a sculptor, painter, and goldsmith, was a remarkable craftsman, and his great skill and passionate concern for quality of execution, as well as his interest in expressing the vital mobility of the human figure, were important elements in Leonardo's artistic formation. Indeed, much in Leonardo's approach to art was evolutionary from tradition rather than revolutionary against it, although the opposite is often true of his results.

Assistant in Verrocchio's Workshop

After completing his apprenticeship, Leonardo stayed on as an assistant in Verrocchio's shop, and his earliest known painting is a product of his collaboration with the master. In Verrocchio's Baptism of Christ (ca. 1475), Leonardo executed one of the two angels, a fact already recorded in the 16th century, as well as the distant landscape, and he added the final touches to the figure of Christ, determining the texture of the flesh. Collaboration on a major project by a master and his assistant was standard procedure in the Italian Renaissance. What is special is that Leonardo's work is not, as was usual, a slightly less skilled version of Verrocchio's manner of painting but an original approach altering it. It completely possesses all the fundamental qualities of Leonardo's mature style and implies a criticism of the early Renaissance. By changing hard metallic surface effects to soft yielding ones, making edges less cutting, and increasing the slight modulations of light and shade, Leonardo evoked a new flexibility within the figures. This "soft union," as Giorgio Vasari called it (1550), is also present in the special lighting and is emphatically developed in the spiral turn of the angel's head and body and the vast depth of the landscape.

Apparently Leonardo had painted one extant work, the Annunciation in Florence, before this. It is much nearer to Verrocchio in the stability of the two figures shown in profile, the clean precision of the decorative details, and the large simple shapes of the trees, but it already differs in the creamier modeling of the faces. A little later is Leonardo's portrait of Ginevra de' Benci, the young wife of a prominent Florentine merchant, in which her oily face with softly contoured lips is seen against a background of mysteriously dark trees and a pond.

Independent Master in Florence

About 1478 Leonardo set up his own studio. In 1481 he received a major church commission for an altarpiece, the Adoration of the Magi. In this unfinished painting, Leonardo's new approach is far more developed. A crowd of spectators, with odd and varied faces, flutters around and peers at the main group of the Virgin and Child, and there is a strong sense of continuing movement. In the background the three horses of the kings prance among intricate architectural ruins. However, the painting also illustrates Leonardo's strong sense of the need for a countervailing order: he placed in the center of the composition the Virgin and Child, who traditionally in paintings of this theme had appeared at one side of the picture, approached by the kings from the other side. Similarly, the picturesque ruins are rendered in sharp perspective.

The simultaneous increase in both the level of activity and the organized system which controls it will climax later in Leonardo's Last Supper, and it shows us his basically scientific temperament - one concerned with not only adding to the quantity of accurate observations of nature but also subjecting these observations to newly inferred physical or mathematical laws. In their paintings earlier Renaissance artists had applied the rules of linear perspective, by which objects appear smaller in proportion as they are farther away from the eye of the spectator. Leonardo joined this principle to two others: perspective of clarity (distant objects progressively lose their separateness and hence are not drawn with outlines) and perspective of color (distant objects progressively tend to a uniform gray tone). He wrote about both of these phenomena in his notebooks.

The Adoration of the Magi was, as noted above, left unfinished. In his later career Leonardo often failed over a period of years to finish a work, essentially because he would not accept established answers. For example, in his project for a bronze equestrian statue he began his work by delving into such matters as the anatomy of horses and the method by which the heavy monument could be transported from his studio to its permanent location. In the case of the Magi altarpiece, however, the unfinished state may merely result from the fact that Leonardo left Florence in 1482 to accept the post of court artist to the Duke of Milan. In leaving, Leonardo followed a trend set by the leading Florentine masters of the older generation, Verrocchio and Antonio Pollaiuolo, who went to Venice and Rome to execute commissions larger than any available in their native Florence.

Milan (1482-1499)

Leonardo presented himself to the Duke of Milan as skilled in many crafts, but particularly in military engineering, asserting that he had worked out improved methods for shooting catapults and diverting rivers. Such inventions, as well as the remarkable machinery that Leonardo produced in Milan for stage pageants, point to his profound interest in the laws of motion and propulsion, a further aspect of his interest in living things and their workings. Again, this preoccupation differs from older artists only in degree.

Leonardo's first Milanese painting is the altarpiece Virgin of the Rocks. It exists in two versions: the one in Paris is earlier and was executed by Leonardo; the one in London is later, and there is controversy as to whether Leonardo participated in its execution. A religious brotherhood in Milan commissioned an altarpiece from Leonardo in 1483, and it is also a matter of argument as to which version is the one commissioned. Some scholars believe that it is the London work and that the Paris version was painted while Leonardo was still in Florence. But this view requires some remarkable coincidences, and the more usual opinion is that the picture in Paris is the original one executed for the Milanese commission and that it was taken away by Leonardo's admirer the king of France and replaced in Milan by the second painting.

Although the Virgin of the Rocks is a very original painting, it makes use of a venerable tradition in which the Holy Family is shown in a cave. This setting becomes a vehicle for Leonardo's interests in depicting nature and in dimmed light, which fuses the outlines of separate objects. The artist once commented that one should practice drawing at dusk and in courtyards with walls painted black. The figures in the painting are grouped in a pyramid.

The other surviving painting of Leonardo's Milanese years is the Last Supper (1495-1497), commissioned by the duke for the refectory of the convent of S. Maria delle Grazie. Instead of using fresco, the traditional medium for this theme, Leonardo experimented with an oil-based medium, because painting in true fresco makes areas of color appear quite distinct. Unfortunately, his experiment was unsuccessful; the paint did not adhere well to the wall, and within 50 years the scene was reduced to a confused series of spots. What we see today is largely a later reconstruction, but the design is reliable and remarkable. The scene seems at first to be one of tumultuous activity, in response to the dramatic stimulus of Christ's words "One of you will betray me," which is a contrast to the traditional static row of figures. But the 12 disciples form four equal clusters around Christ, isolated as a fifth unit in the middle. Thus, Leonardo once again enriches the empirical observation of vital activity but simultaneously develops a containing formula and emphasizes the center. This blend of the immediate reality of the situation and the underlying order of the composition is perhaps the reason the painting has always been extraordinarily popular and has remained the standard image of the subject.

In its own time, the Last Supper was perhaps less well known than the project for a bronze equestrian statue of the previous Duke of Milan, on which Leonardo worked during most of his Milanese years. He wanted to show the horse leaping, a technical problem of balance in sculpture that was solved only in the 17th century. Numerous drawings of the project exist.

Besides apparatus for pageants and artillery, architectural projects also occupied Leonardo in Milan. He and the great architect Donato Bramante, also a recent arrival at the court, clearly had a mutually stimulating effect, and it is hard to attribute certain innovative ideas to one of them rather than the other. The architectural drawings of Leonardo, very similar to the buildings of Bramante, mark the shift from the early Renaissance to the High Renaissance in architecture and show a new interest in and command of scale and grandeur within the basic harmonious geometry of Renaissance structure. No buildings can be attributed with certainty to Leonardo.

When Leonardo's patron was overthrown by the French invasion in 1499, Leonardo left Milan. He visited Venice briefly, where the Senate consulted him on military projects, and Mantua. He planned a portrait of Isabella d'Este, Duchess of Mantua, one of the most striking personalities and great art patrons of the age. The surviving drawing for this portrait suggests that the concept of the later Mona Lisa had already been formulated.

Florence (1500-1506)

In 1500 Leonardo returned to Florence, where he was received as a great man. Florentine painters of the generation immediately following Leonardo were excited by his modern methods, with which they were familiar through the unfinished Adoration of the Magi, and he also now had a powerful effect on a still younger group of artists. Thus it was that a younger master passed on to Leonardo his own commission for the Virgin and Child with St. Anne, and the monks who had ordered it gave Leonardo a workroom. Leonardo's large preparatory drawing was inspected by crowds of viewers. This theme had traditionally been presented in a rather diagrammatic fashion to illustrate the family tree of Christ; sometimes this was done by representing Anne, the grandmother, in large scale with her daughter Mary on her knee and with Mary in turn holding the Christ Child. Leonardo sought to retain a reference to this conceptual pattern while drawing sinuous, smiling figures in a fluid organic interrelationship. Several varying designs exist, the last version being the painting of about 1510 in Paris; this variety suggests that Leonardo could not fuse the two qualities he desired: an abstract formula and the immediacy of life.

During his years in Florence (1500-1506), even though they were interrupted in 1502 by a term as military engineer for Cesare Borgia, Leonardo completed more projects than in any other period of his life. In his works of these years, the emphasis is almost exclusively on portraying human vitality, as in the Leda and the Swan (lost; known only through copies), a spiraling figure kneeling among reeds, and the Mona Lisa, the portrait of a Florentine citizen's young third wife, whose smile is mysterious because it is in the process of either appearing or disappearing.

Leonardo's great project (begun 1503) was the battle scene that the city commissioned to adorn the newly built Council Hall of the Palazzo Vecchio. In the choice of theme, the Battle of Anghiari, patriotic references and the wish to show off Leonardo's special skills were both apparently required. Leonardo depicted a cavalry battle - a small skirmish won by Florentine troops - in which horsemen leap at each other, churning up dust, in quick interlocking motion. The work today is known through some rapid rough sketches of the groups of horsemen, careful drawings of single heads of men which are extraordinarily vivid in suggesting immediate response to a stimulus, and copies of the entire composition. Leonardo began to paint the scene, experimenting with encaustic technique (the paint is fused into hot wax on the surface of the panel), but he was called back to Milan before the work was completed. A short time thereafter, the room was remodeled and the fragment was destroyed.

Both the Battle of Anghiari and the Mona Lisa contain their animation in neatly balanced designs. In the battle scene, the enemies are locked in tense symmetry; in the portrait, the crossed arms form the base of a pyramid capped by the head, which gives the lady her quality of classic rightness and prevents the less than full-length portrait from seeming incomplete and arbitrarily amputated at the lower edge.

Milan (1506-1513)

Called to Milan in 1506 by the French governor in charge, Leonardo worked on an equestrian statue project, but he produced no new paintings. Instead he now turned more and more to scientific observation. Most of his scientific concerns were fairly direct extensions of his interests as a painter, and his research in anatomy was the most fully developed. Verrocchio and other early Renaissance painters had attempted to render the human anatomy with accuracy, but Leonardo went far beyond any of them, producing the earliest anatomical drawings which are still considered valid today, although he occasionally confused animal and human anatomy and accepted some old wives' tales.

The notebooks Leonardo was now filling with data and drawings, later piously arranged by his heirs, and the visual intensity that was always his starting point reveal his other scientific interests also: firearms, the action of water, the flight of birds (leading to designs for human flight), the growth of plants, and geology. Leonardo's interests were not universal: theology, history, and literature moved him little. All his interests had in common a concern with the processes of action, movement, pressure, and growth; it has been rightly said that his drawings of the human body are less anatomical than physiological.

Last Years

In 1513 Leonardo went to Rome, where he remained until 1516. He was much honored, but he was relatively inactive and remarkably aloof from its rich social and artistic life. He continued to fill his notebooks with scientific entries.

The French king, Francis I, invited Leonardo to his court at Fontainebleau, gave him the title of first painter, architect, and mechanic to the king, and provided him with a country house at Cloux. Leonardo was revered for his knowledge more than for any work he produced in France. He died on May 2, 1519, at Cloux.

His Influence

Leonardo's influence on younger artists was enormous; it is often said to have first affected his teacher, Verrocchio. By the time Leonardo left Florence in 1482, he had already begun to influence the city's most talented younger painter, Filippino Lippi, only 5 years his junior. During the 1490s Filippino and Piero di Cosimo, another admirer of Leonardo, were the leading painters in Florence. In Milan, Leonardo overwhelmingly dominated a rather weak generation of artists, who were soon turning out smiling Madonnas in imitation of his style.

Leonardo's greatest impact came in Florence just after his return in 1500, when young artists already conditioned by the master's early work were able to absorb and transmit his message rather than merely copy the superficial aspects of his style. Fra Bartolommeo soon reflected this new approach, as did Andrea del Sarto shortly afterward.

On a subtle and more significant level, Leonardo at this time transformed the two greatest young artists to come in contact with him. Raphael came to Florence in 1504 at the age of 21, eager to increase his knowledge of perspective and anatomy, and he quickly revealed Leonardo's influence in his portraits and Madonnas; his results were less intellectual, psychological, and energetic and more coolly formal, but with Leonardo's vitality. About 1503 Michelangelo changed from a sculptor of merely grand scale to one whose figures are charged with energy. This may be seen in the contrast between Michelangelo's David and St. Matthew.

From this time on Leonardo influenced, directly or indirectly, all painting, as Vasari implies. His influence on science was much less, although his drawings may have been known to the anatomist Andreas Vesalius and had an effect on his great publication of 1543. However, most of Leonardo's scientific observations remained unknown until the same questions were again investigated in later centuries.

(1452–1519)

Uomo Universale of the Italian Renaissance, he made important contributions to architectural theory and town-planning. He was involved in preliminary studies for the crossing of Milan Cathedral (c.1487) and, with Francesco di Giorgio, was consulted about the building of Pavia Cathedral in c.1490. He provided plans for Milan's urban renewal and expansion (1490s), and produced sketches in which his interest in relating buildings geometrically to streets, squares, and gardens using axes is demonstrated. Like others of his time, he was fascinated by the possibilities of centrally planned domed buildings, and in this respect his relationship with Bramante in Milan is important, for the two men developed their ideas under the aegis of the Sforza family. Leonardo was involved with Bramante in the design of the domed crossing and chancel of Santa Maria delle Grazie, Milan (1490s), intended as a mausoleum for the Sforzas, and painted his beautiful Last Supper (which contains an architectural setting of remarkable modernity for its date, almost anticipating Palladio) in the refectory (c.1495). It would seem that the maturing of Bramante's style to the gravitas of his Tempietto at San Pietro in Montorio, Rome, and his development of centralized geometries at the basilica of San Pietro, Rome, may be due in no small part to Leonardo's influence.

Leonardo's notebooks give a fascinating glimpse of his architectural interests. Apart from his important scientific and mechanical drawings, his lively mind often experimented with the Classical vocabulary in a way that looked forward to much later developments. Fortifications, centralized plans, and technology were all his concerns, but there are also studies of designs for villas (c.1506) that anticipate Palladianism, and even Mannerism, with columns inserted in recesses, something Michelangelo was to do years later. With Bramante, he seems to have acted as some kind of adviser for the Church of Santa Maria della Consolazione at Todi (1508), begun by Cola da Caprarola. In his last years Leonardo worked in France, planning a vast Royal residence and settlement at Romorantin (c.1517–19), complete with huge canals linking the English Channel to the Mediterranean.

Leonardo Da Vinci's workshop, which was located in the Santissima Annunziata convent, in Florence, was discovered last month. It still had several of Da Vinci's frescoes on the walls. Some believe that Lisa Gherardini, the woman who was most likely the model for his painting, the Mona Lisa, worshipped at the convent. (story)

Leonardo da Vinci (də vĭn'chē, Ital. lāōnär'dō dä vēn'chē), 1452-1519, Italian painter, sculptor, architect, musician, engineer, and scientist, b. near Vinci, a hill village in Tuscany. The versatility and creative power of Leonardo mark him as a supreme example of Renaissance genius. He depicted in his drawings, with scientific precision and consummate artistry, subjects ranging from flying machines to caricatures; he also executed intricate anatomical studies of people, animals, and plants. The richness and originality of intellect expressed in his notebooks reveal one of the greatest minds of all time.

Early Life and Work: Vinci and Florence

Leonardo was the illegitimate son of a Florentine notary and a peasant woman. Presumably he passed his childhood with his father's family in Vinci, where he developed an enduring interest in nature. Early sources describe his beauty, charm of manner, and precocious display of artistic talent.

In 1466 Leonardo moved to Florence, where he entered the workshop of Verrocchio and came into contact with such artists as Botticelli, Ghirlandaio, and Lorenzo di Credi. Early in his apprenticeship he painted an angel, and perhaps portions of the landscape, in Verrocchio's Baptism of Christ (Uffizi). In 1472 he was registered in the painters' guild. The culmination of Leonardo's art during his first period in Florence is the magnificent unfinished Adoration of the Magi (Uffizi) commissioned in 1481 by the monks of San Donato a Scopeto. In this work is revealed the integration of dramatic movement and chiaroscuro that characterizes the master's mature style.

Middle Life and Mature Work: Milan and Florence

Leonardo went to Milan c.1482 and remained at the court of Ludovico Sforza for 16 years. In this time he composed the greater part of his Trattato della pittura and the extensive notebooks that demonstrate the marvelous versatility and penetration of his genius. As court artist he also organized elaborate festivals. Severe plagues in 1484 and 1485 drew his attention to problems of town planning, an interest which was revived during his last years in France. Many drawings of plans and elevations for domed churches reflect a concern with architectural problems that must have been stimulated by contact with Bramante during these years. He worked c.1488 on a model for the tambour and dome of the cathedral at Milan. In 1490 he was employed with Francesco di Giorgio as consulting engineer on the restoration of the cathedral at Pavia and later on the cathedral at Piacenza.

In 1483, Leonardo, with his pupil Ambrogio de Predis, was commissioned to execute the famous Madonna of the Rocks. Two versions of the painting exist-one in the Louvre (1483-c.1486), another in the National Gallery, London (1483-1508). Leonardo's fresco of the Last Supper (Milan) was begun c.1495 and completed by 1498. This work is now badly damaged. Leonardo's own experiments with the fresco medium account in part for its disintegration, which was already noticed by 1517. Deterioration and repeated restorations had obliterated details and individual figures. Nonetheless, the composition and general disposition of the figures reveal a power of invention and a sublimity of spiritual content that mark the painting among the world's masterpieces. In 1978 a major (and controversial) restoration was begun, and in 1994-95 protective air-filtration and climate-control equipment were installed. The restoration was completed in 1999, leaving the fresco brightened considerably with details clarified, but also revealing the extensive loss of the original painting.

While at Ludovico's court Leonardo also worked on an equestrian monument to the duke's father, Francesco Sforza. The work was never cast, and the model, admired by his contemporaries, perished during the French invasion of 1499. In 1511 he undertook a similar work with the commission of an equestrian monument for Gian Giacomo Trivulzio. This work was also never completed and known only through drawings related to the project. After the fall (1499) of Ludovico Sforza, Leonardo left Milan and, following brief sojourns in Mantua and Venice, returned to Florence in 1500.

Back in Florence Leonardo engaged in much theoretical work in mathematics and pursued his anatomical studies at the hospital of Santa Maria Nuova. In 1502 he entered the service of Cesare Borgia as a military engineer. His engagement took him to central Italy to study swamp reclamation projects in Piombino and to tour the cities of Romagna. At Urbino he met Niccolò Machiavelli, who later became a close friend.

By 1503 he was back in Florence, where he was commissioned to execute the fresco of the battle of Anghiari. This work, like its companion piece assigned to Michelangelo, was never completed, and the cartoons were subsequently destroyed. The work exerted enormous influence on later artists, however, and some impression of the original may be had from anonymous copies in the Uffizi and Casa Horne (Florence), from an engraving of 1558 of Lorenzo Zacchia, and from a drawing by Rubens (Louvre). From about this time dates the celebrated Mona Lisa (Louvre), the portrait of the wife of a Florentine merchant.

In 1506, Leonardo returned to Milan, engaged by Charles d'Amboise in the name of the French king, Louis XII. Here he again served as architect and engineer. Gifted with a gargantuan curiosity concerning the physical world, he continued his scientific investigations, concerning himself with problems of geology, botany, hydraulics, and mechanics. In 1510-11 his interest in anatomy quickened considerably. At the same time he was active as painter and sculptor, had many pupils, and profoundly influenced the Milanese painters. A painting generally ascribed to this period is the St. Anne, Mary, and the Child (Louvre), a work that exemplifies Leonardo's handling of sfumato-misty, subtle transitions in tone.

Late Life and Work: Rome and France

In 1513 Leonardo went to Rome, attracted by the patronage of the newly elected Medici pope, Leo X, and his brother Giuliano. Here he found the field dominated by Michelangelo and Raphael. The aging master was assigned to various architectural and engineering projects at the Vatican and received commissions for several paintings. It was perhaps in this period that he executed the enigmatic painting of the young St. John the Baptist (Louvre). Giuliano de' Medici left Rome in 1515 and died at Fiesole in the following year.

It is conjectured that Leonardo left with him, attached to his household, and that soon afterward he accepted an invitation of Francis I of France to settle at the castle of Cloux, near Amboise. Here the old master was left entirely free to pursue his own researches until his death. Although there is no certain record of his last years, he seems to have been active with festival decoration and to have been interested in a canal project. Notes and drawings ascribed to this late period show his continued interest in natural philosophy and experimental science.

Leonardo Da Vinci (1452–1519), Italian painter, sculptor, architect, and inventor. The illegitimate son of a young notary and a farm girl, both of whom married other people of their own social station shortly after his birth, Leonardo was adopted into his father's household when his stepmother remained childless. Unlike his father, Ser Pietro, who had learned Latin in connection with his profession, Leonardo, for all his evident intelligence, proved a poor and distracted student; he received the arithmetical training known as "abacus school" (scuola di abbaco) and then seems to have quit his formal schooling to be apprenticed to the famous Florentine sculptor Andrea del Verrocchio (1435–1488).

Leonardo's first biographer, Giorgio Vasari (1511–1574), tells how the young apprentice painted so ethereal an angel for Verrocchio's Baptism of Christ that the master threw up his hands and admitted defeat. But Verrocchio also helped to create Leonardo's famous sfumato or "smudged" shading technique, and encouraged his reliance on drawing as the chief medium for artistic composition, whether in painting, sculpture, architecture, or mechanics. Leonardo's first independent commission, an altarpiece for the Chapel of Saint Bernard in Palazzo della Signoria, contracted in 1478, was never completed, and this unfinished business set a pattern for the rest of his life. When his father procured for him the assignment of an altarpiece with the Adoration of the Magi for the Augustinian Canons Regular at San Donato in 1481, he put in several months of hard work on the ambitious painting, then abruptly left Florence for Milan in September, where he joined the court of Ludovico Sforza (duke of Milan 1481–1499).

This move represented more than a change of place; it also brought on a change in Leonardo's whole way of life. Florence, despite the heavy hand of the Medici clan in every government office and public commission, was nominally a republic, a large city-state with an elaborate set of public institutions. Ludovico, on the other hand, was a professional soldier who had seized Milan by force and aimed to keep control of the city by maintaining an efficient system of government and an active cultural life.

Leonardo seems to have applied to Ludovico Sforza with an offer to serve as a military architect. He spent much of his time with Donato Bramante (1444–1514) and the mathematician Luca Pacioli, providing the illustrations for Pacioli's popular book On Divine Proportion (1509), some of them originally pillaged from Piero della Francesca

Sometime between 1493 and 1495, Leonardo obtained the commission to decorate the refectory of the Dominican convent of Santa Maria delle Grazie with a Last Supper. The fresco was widely influential despite the failure of Leonardo's experimental formula for its paint, which began to deteriorate almost immediately.

In 1494, Charles VIII, the king of France, invaded Italy. By 1499, Milan had fallen to French troops, who imprisoned Ludovico. Leonardo, in the company of Luca Pacioli, returned to Florence, but not before he had seen the huge clay model for his never-completed statue of Francesco Sforza used for target practice by Gascon bowmen.

In 1502 Leonardo worked briefly as a military engineer in central Italy for Cesare Borgia. When Borgia's military campaigns began to be reined in by his father, Rodrigo (later Pope Alexander VI; reigned 1492–1503), Leonardo again returned to the Florentine republic, where an extensive remodeling of the great city hall, the Palazzo della Signoria, was under way. Here, in a monumental room designed to hold the republic's new representative council, Leonardo was asked to paint scenes from the battle of Anghiari, a skirmish in which Florence had gotten the best of her inveterate rival (and sometime port) Pisa. On the opposite wall, the city council had engaged Michelangelo Buonarroti, whose newly completed David still provides the most eloquent testimony to the indomitable spirit of this early-sixteenth-century Florentine republic.

Leonardo worked up at least part of his design for the Battle of Anghiari (begun 1503) to full size and transferred it to the wall of the council hall, but he decided to paint it in a medium that would lend the chalky plaster surface of the fresco something of the sheen of oil paint. The experiment failed miserably, and Leonardo never finished the work. It was finally covered by another fresco executed by Giorgio Vasari. Also in Florence, Leonardo became preoccupied with water and its motions. Another side of nature shows forth in Leonardo's sketches for his lost painting of Leda and the Swan.

From 1506 to 1513, Leonardo moved between Milan and Florence, evading the irate city councilmen who clamored for the rest of their Battle of Anghiari and also evading the violent skirmishes that plagued the area around Milan. He filled a series of notebooks with his writings, sketches, and anatomical studies. In 1512, the Florentine republic fell to a restored Medici dynasty; in 1513, Medici rule was reinforced by the election in Rome of a Medici pope, Leo X (reigned 1513–1521), son of Lorenzo the Magnificent. When the pope invested his brother, Giuliano de' Medici, with honorary Roman citizenship, Leonardo traveled with Giuliano's entourage and continued to study and write from his own special apartment in the Vatican Palace. In a city dominated by the imposing influence of Raphael, who had transformed himself from a painter to a designer (disegnatore) of international fame, Leonardo began to compile his own notes on painting, which would eventually be gathered together by his pupil Francesco Melzi and published in 1651 as Treatise on Painting.

In 1516, the aging artist accepted an invitation to become peintre du roi by Francis I of France and moved north with Melzi and his servant Salai. He died there in 1519 at the age of sixty-seven.

An Italian artist, scientist, and inventor of the late fifteenth and early sixteenth centuries. His wide range of interests and abilities makes him a grand example of a “Renaissance man.” Leonardo painted the Mona Lisa and The Last Supper. His drawings include brilliant studies of the human body and of natural objects. Some of his sketches anticipate modern inventions such as the airplane and the tank.

(1452–1519). Italian sculptor, painter, architect, and engineer–inventor, born at Vinci near Florence, the natural son of a notary. He was apprenticed to Verrocchio (about 1470) in Florence and in 1482 settled in Milan, working with Lodovico Sforza. In 1502 Leonardo entered the service of Cesare Borgia, as architect and engineer. The Mona Lisa was painted about 1504.

Leonardo's Notebooks are of great interest in describing his work and ideas on hydraulics, the casting of statues, and many inventions, as well as in giving his advice to painters and clear accounts of perspective and the use of shadow. He did not, however, appreciate that the two eyes give perception of depth (by stereopsis), and he wrongly thought that light must cross twice in the eye to produce a right-way-up retinal image, for perception to be non-inverted. He was also confused on why mirrors normally reverse left and right but not up and down — see MacCurdy (1938: vol. i, ch. 9). Leonardo recognized, however, many properties of the eye, such as 'irradiation' — bright objects appearing larger than dark ones — and his anatomical drawings are masterpieces, even though they sometimes incorporate features which he believed present when in fact they are not. Leonardo is generally recognized as the most universal genius of all time.

A feature of Leonardo's Notebooks of particular psychological interest is that these manuscripts were consistently written in mirror script. As is well known, mirror writing is not an altogether uncommon accomplishment, particularly among the left-handed. Although Leonardo's handedness is not reliably known, some experts have claimed that careful study of the detail and shading of his marginal sketches indicates that — at all events before he sustained a partial left-sided paralysis in later life — the pen was held in his left hand. It appears probable, therefore, that Leonardo was naturally left-handed and, like some other left-handed individuals, had a particular facility in mirror writing.

Leonardo di ser Piero da Vinci (About this sound pronunciation ) (April 15, 1452 – May 2, 1519, Old Style) was an Italian Renaissance polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination".[1] He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived.[2] According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote".[1] Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time.[3]

Born out of wedlock to a notary, Piero da Vinci, and a peasant woman, Caterina, at Vinci in the region of Florence, Leonardo was educated in the studio of the renowned Florentine painter, Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice, and he spent his last years in France at the home awarded him by Francis I.

Leonardo was and is renowned[2] primarily as a painter. Among his works, the Mona Lisa is the most famous and most parodied portrait and The Last Supper the most reproduced religious painting of all time, with their fame approached only by Michelangelo's The Creation of Adam.[1] Leonardo's drawing of the Vitruvian Man is also regarded as a cultural icon,[4] being reproduced on items as varied as the euro, textbooks, and T-shirts. Perhaps fifteen of his paintings survive, the small number because of his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination.[nb 2] Nevertheless, these few works, together with his notebooks, which contain drawings, scientific diagrams, and his thoughts on the nature of painting, compose a contribution to later generations of artists only rivalled by that of his contemporary, Michelangelo.

Leonardo is revered[2] for his technological ingenuity. He conceptualised a helicopter, a tank, concentrated solar power, a calculator,[5] the double hull, and he outlined a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime,[nb 3] but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded.[nb 4] He made important discoveries in anatomy, civil engineering, optics, and hydrodynamics, but he did not publish his findings and they had no direct influence on later science.[6]

Leonardo was born on April 15, 1452 (Old Style), "at the third hour of the night"[nb 5] in the Tuscan hill town of Vinci, in the lower valley of the Arno River in the territory of the Medici-ruled Republic of Florence.[8] He was the out-of-wedlock son of the wealthy Messer Piero Fruosino di Antonio da Vinci, a Florentine legal notary, and Caterina, a peasant.[7][9][nb 6] Leonardo had no surname in the modern sense, “da Vinci” simply meaning “of Vinci”: his full birth name was "Lionardo di ser Piero da Vinci", meaning "Leonardo, (son) of (Mes)ser Piero from Vinci".[8] The inclusion of the title "ser" indicated that Leonardo's father was a gentleman.

Little is known about Leonardo's early life. He spent his first five years in the hamlet of Anchiano in the home of his mother, then from 1457 he lived in the household of his father, grandparents and uncle, Francesco, in the small town of Vinci. His father had married a sixteen-year-old girl named Albiera, who loved Leonardo but died young.[10] When Leonardo was sixteen his father married again, to twenty-year-old Francesca Lanfredini. It was not until his third and fourth marriages that Ser Piero produced legitimate heirs.[11]

Leonardo received an informal education in Latin, geometry and mathematics. In later life, Leonardo only recorded two childhood incidents. One, which he regarded as an omen, was when a kite dropped from the sky and hovered over his cradle, its tail feathers brushing his face.[12] The second occurred while exploring in the mountains. He discovered a cave and was both terrified that some great monster might lurk there and driven by curiosity to find out what was inside.[10]

Leonardo's early life has been the subject of historical conjecture.[13] Vasari, the 16th-century biographer of Renaissance painters tells of how a local peasant made himself a round shield and requested that Ser Piero have it painted for him. Leonardo responded with a painting of a monster spitting fire which was so terrifying that Ser Piero sold it to a Florentine art dealer, who sold it to the Duke of Milan. Meanwhile, having made a profit, Ser Piero bought a shield decorated with a heart pierced by an arrow, which he gave to the peasant.[14]

The Baptism of Christ (1472–1475)—Uffizi, by Verrocchio and Leonardo

Verrocchio's workshop, 1466–1476

In 1466, at the age of fourteen, Leonardo was apprenticed to the artist Andrea di Cione, known as Verrocchio, whose workshop was "one of the finest in Florence".[15] Other famous painters apprenticed or associated with the workshop include Domenico Ghirlandaio, Perugino, Botticelli, and Lorenzo di Credi.[10][16] Leonardo would have been exposed to both theoretical training and a vast range of technical skills[17] including drafting, chemistry, metallurgy, metal working, plaster casting, leather working, mechanics and carpentry as well as the artistic skills of drawing, painting, sculpting and modelling.[18][nb 7]

Much of the painted production of Verrocchio's workshop was done by his employees. According to Vasari, Leonardo collaborated with Verrocchio on his Baptism of Christ, painting the young angel holding Jesus' robe in a manner that was so far superior to his master's that Verrocchio put down his brush and never painted again.[19] On close examination, the painting reveals much that has been painted or touched up over the tempera using the new technique of oil paint, with the landscape, the rocks that can be seen through the brown mountain stream and much of the figure of Jesus bearing witness to the hand of Leonardo.[20] Leonardo may have been the model for two works by Verrocchio: the bronze statue of David in the Bargello and the Archangel Raphael in Tobias and the Angel.[9]

By 1472, at the age of twenty, Leonardo qualified as a master in the Guild of St Luke, the guild of artists and doctors of medicine,[nb 8] but even after his father set him up in his own workshop, his attachment to Verrocchio was such that he continued to collaborate with him.[10] Leonardo's earliest known dated work is a drawing in pen and ink of the Arno valley, drawn on August 5, 1473.[nb 9][16]

Professional life, 1476–1513

Florentine court records of 1476 show that Leonardo and three other young men were charged with sodomy and acquitted.[9][nb 10] From that date until 1478 there is no record of his work or even of his whereabouts.[21] In 1478 he left Verrocchio's studio and was no longer resident at his father's house. One writer, the "Anonimo" Gaddiano claims that in 1480 he was living with the Medici and working in the Garden of the Piazza San Marco in Florence, a Neo-Platonic academy of artists, poets and philosophers that the Medici had established.[9] In January 1478, he received his first of two independent commissions: to paint an altarpiece for the Chapel of St. Bernard in the Palazzo Vecchio and, in March 1481, The Adoration of the Magi for the Monks of San Donato a Scopeto.[22] Neither commission was completed, the second being interrupted when Leonardo went to Milan.

In 1482 Leonardo, who according to Vasari was a most talented musician,[23] created a silver lyre in the shape of a horse's head. Lorenzo de' Medici sent Leonardo to Milan, bearing the lyre as a gift, to secure peace with Ludovico il Moro, Duke of Milan.[24] At this time Leonardo wrote an often-quoted letter describing the many marvellous and diverse things that he could achieve in the field of engineering and informing Ludovico that he could also paint.[16][25]

Leonardo worked in Milan from 1482 until 1499. He was commissioned to paint the Virgin of the Rocks for the Confraternity of the Immaculate Conception and The Last Supper for the monastery of Santa Maria delle Grazie.[26] Between 1493 and 1495 Leonardo listed a woman called Caterina among his dependents in his taxation documents. When she died in 1495, the list of funeral expenditures suggests that she was his mother.[27]

Leonardo was employed on many different projects for Ludovico, including the preparation of floats and pageants for special occasions, designs for a dome for Milan Cathedral and a model for a huge equestrian monument to Francesco Sforza, Ludovico's predecessor. Seventy tons of bronze were set aside for casting it. The monument remained unfinished for several years, which was not unusual for Leonardo. In 1492 the clay model of the horse was completed. It surpassed in size the only two large equestrian statues of the Renaissance, Donatello's statue of Gattemelata in Padua and Verrocchio's Bartolomeo Colleoni in Venice, and became known as the "Gran Cavallo".[16][nb 11]

Leonardo began making detailed plans for its casting,[16] however, Michelangelo insulted Leonardo by implying that he was unable to cast it.[10] In November 1494 Ludovico gave the bronze to be used for cannon to defend the city from invasion by Charles VIII.[16]

At the start of the Second Italian War in 1499, the invading French troops used the life-size clay model for the "Gran Cavallo" for target practice. With Ludovico Sforza overthrown, Leonardo, with his assistant Salai and friend, the mathematician Luca Pacioli, fled Milan for Venice[28] where he was employed as a military architect and engineer, devising methods to defend the city from naval attack.[10] On his return to Florence in 1500, he and his household were guests of the Servite monks at the monastery of Santissima Annunziata and were provided with a workshop where, according to Vasari, Leonardo created the cartoon of The Virgin and Child with St. Anne and St. John the Baptist, a work that won such admiration that "men and women, young and old" flocked to see it "as if they were attending a great festival".[29][nb 12]

In Cesena, in 1502 Leonardo entered the service of Cesare Borgia, the son of Pope Alexander VI, acting as a military architect and engineer and travelling throughout Italy with his patron.[28] Leonardo created a map of Cesare Borgia's stronghold, a town plan of Imola in order to win his patronage. Maps were extremely rare at the time and it would have seemed like a new concept; upon seeing it, Cesare hired Leonardo as his chief military engineer and architect. Later in the year, Leonardo produced another map for his patron, one of Chiana Valley, Tuscany so as to give his patron a better overlay of the land and greater strategic position. He created this map in conjunction with his other project of constructing a dam from the sea to Florence in order to allow a supply of water to sustain the canal during all seasons.

Leonardo returned to Florence where he rejoined the Guild of St Luke on October 18, 1503, and spent two years designing and painting a mural of The Battle of Anghiari for the Signoria,[28] with Michelangelo designing its companion piece, The Battle of Cascina.[nb 13] In Florence in 1504, he was part of a committee formed to relocate, against the artist's will, Michelangelo's statue of David.[33]

In 1506 Leonardo returned to Milan. Many of his most prominent pupils or followers in painting either knew or worked with him in Milan,[10] including Bernardino Luini, Giovanni Antonio Boltraffio and Marco D'Oggione.[nb 14] However, he did not stay in Milan for long because his father had died in 1504, and in 1507 he was back in Florence trying to sort out problems with his brothers over his father's estate. By 1508 Leonardo was back in Milan, living in his own house in Porta Orientale in the parish of Santa Babila.[34]

Old age, 1513–1519

From September 1513 to 1516, Leonardo spent much of his time living in the Belvedere in the Vatican in Rome, where Raphael and Michelangelo were both active at the time.[34] In October 1515, Francis I of France recaptured Milan.[22] On December 19, Leonardo was present at the meeting of Francis I and Pope Leo X, which took place in Bologna.[10][35][36] Leonardo was commissioned to make for Francis a mechanical lion which could walk forward, then open its chest to reveal a cluster of lilies.[37][nb 15] In 1516, he entered François' service, being given the use of the manor house Clos Lucé[nb 16] near the king's residence at the royal Château d'Amboise. It was here that he spent the last three years of his life, accompanied by his friend and apprentice, Count Francesco Melzi, and supported by a pension totalling 10,000 scudi.[34]

Clos Lucé in France, where Leonardo died in 1519

Leonardo died at Clos Lucé, on May 2, 1519. Francis I had become a close friend. Vasari records that the king held Leonardo's head in his arms as he died, although this story, beloved by the French and portrayed in romantic paintings by Ingres, Ménageot and other French artists, as well as by Angelica Kauffmann, may be legend rather than fact.[nb 17] Vasari states that in his last days, Leonardo sent for a priest to make his confession and to receive the Holy Sacrament.[39] In accordance to his will, sixty beggars followed his casket.[nb 18] He was buried in the Chapel of Saint-Hubert in Château d'Amboise. Melzi was the principal heir and executor, receiving as well as money, Leonardo's paintings, tools, library and personal effects. Leonardo also remembered his other long-time pupil and companion, Salai and his servant Battista di Vilussis, who each received half of Leonardo's vineyards, his brothers who received land, and his serving woman who received a black cloak "of good stuff" with a fur edge.[nb 19][40]

Some twenty years after Leonardo's death, Francis was reported by the goldsmith and sculptor Benevenuto Cellini as saying: "There had never been another man born in the world who knew as much as Leonardo, not so much about painting, sculpture and architecture, as that he was a very great philosopher."[41]

Relationships and influences

Ghiberti's Gates of Paradise, (1425–1452) were a source of communal pride. Many artists assisted in their creation.

Florence — Leonardo's artistic and social background

Florence, at the time of Leonardo's youth, was the centre of Christian Humanist thought and culture.[15] Leonardo commenced his apprenticeship with Verrocchio in 1466, the year that Verrocchio's master, the great sculptor Donatello, died. The painter Uccello, whose early experiments with perspective were to influence the development of landscape painting, was a very old man. The painters Piero della Francesca and Fra Filippo Lippi, sculptor Luca della Robbia, and architect and writer Leon Battista Alberti were in their sixties. The successful artists of the next generation were Leonardo's teacher Verrocchio, Antonio Pollaiuolo and the portrait sculptor, Mino da Fiesole whose lifelike busts give the most reliable likenesses of Lorenzo Medici's father Piero and uncle Giovanni.[42][43][44][45]

Leonardo's youth was spent in a Florence that was ornamented by the works of these artists and by Donatello's contemporaries, Masaccio whose figurative frescoes were imbued with realism and emotion and Ghiberti whose Gates of Paradise, gleaming with gold leaf, displayed the art of combining complex figure compositions with detailed architectural backgrounds. Piero della Francesca had made a detailed study of perspective,[46] and was the first painter to make a scientific study of light. These studies and Alberti's Treatise[47] were to have a profound effect on younger artists and in particular on Leonardo's own observations and artworks.[42][44][45]

Massaccio's "The Expulsion from the Garden of Eden" depicting the naked and distraught Adam and Eve created a powerfully expressive image of the human form, cast into three dimensions by the use of light and shade which was to be developed in the works of Leonardo in a way that was to be influential in the course of painting. The humanist influence of Donatello's "David" can be seen in Leonardo's late paintings, particularly John the Baptist.[42][43]

Small devotional picture by Verrocchio, c. 1470

A prevalent tradition in Florence was the small altarpiece of the Virgin and Child. Many of these were created in tempera or glazed terracotta by the workshops of Filippo Lippi, Verrocchio and the prolific della Robbia family.[42] Leonardo's early Madonnas such as The Madonna with a carnation and The Benois Madonna followed this tradition while showing idiosyncratic departures, particularly in the case of the Benois Madonna in which the Virgin is set at an oblique angle to the picture space with the Christ Child at the opposite angle. This compositional theme was to emerge in Leonardo's later paintings such as The Virgin and Child with St. Anne.[10]

Leonardo was a contemporary of Botticelli, Domenico Ghirlandaio and Perugino, who were all slightly older than he was.[43] He would have met them at the workshop of Verrocchio, with whom they had associations, and at the Academy of the Medici.[10] Botticelli was a particular favourite of the Medici family, and thus his success as a painter was assured. Ghirlandaio and Perugino were both prolific and ran large workshops. They competently delivered commissions to well-satisfied patrons who appreciated Ghirlandaio's ability to portray the wealthy citizens of Florence within large religious frescoes, and Perugino's ability to deliver a multitude of saints and angels of unfailing sweetness and innocence.[42]

The Portinari Altarpiece, by Hugo van der Goes for a Florentine family

These three were among those commissioned to paint the walls of the Sistine Chapel, the work commencing with Perugino's employment in 1479. Leonardo was not part of this prestigious commission. His first significant commission, The Adoration of the Magi for the Monks of Scopeto, was never completed.[10]

In 1476, during the time of Leonardo's association with Verrocchio's workshop, the Portinari Altarpiece by Hugo van der Goes arrived in Florence, bringing new painterly techniques from Northern Europe which were to profoundly effect Leonardo, Ghirlandaio, Perugino and others.[43] In 1479, the Sicilian painter Antonello da Messina, who worked exclusively in oils, traveled north on his way to Venice, where the leading painter Giovanni Bellini adopted the technique of oil painting, quickly making it the preferred method in Venice. Leonardo was also later to visit Venice.[43][45]

Like the two contemporary architects Bramante and Antonio da Sangallo the Elder Leonardo experimented with designs for centrally planned churches, a number of which appear in his journals, as both plans and views, although none was ever realised.[43][48]

Leonardo's political contemporaries were Lorenzo Medici (il Magnifico), who was three years older, and his younger brother Giuliano who was slain in the Pazzi Conspiracy in 1478. Ludovico il Moro who ruled Milan between 1479–1499 and to whom Leonardo was sent as ambassador from the Medici court, was also of Leonardo's age.[43]

With Alberti, Leonardo visited the home of the Medici and through them came to know the older Humanist philosophers of whom Marsiglio Ficino, proponent of Neo Platonism; Cristoforo Landino, writer of commentaries on Classical writings, and John Argyropoulos, teacher of Greek and translator of Aristotle were the foremost. Also associated with the Academy of the Medici was Leonardo's contemporary, the brilliant young poet and philosopher Pico della Mirandola.[43][45][49] Leonardo later wrote in the margin of a journal "The Medici made me and the Medici destroyed me." While it was through the action of Lorenzo that Leonardo received his employment at the court of Milan, it is not known exactly what Leonardo meant by this cryptic comment.[10]

Although usually named together as the three giants of the High Renaissance, Leonardo, Michelangelo and Raphael were not of the same generation. Leonardo was twenty-three when Michelangelo was born and thirty-one when Raphael was born.[43] Raphael only lived until the age of 37 and died in 1520, the year after Leonardo, but Michelangelo went on creating for another 45 years.[44][45]

Personal life

Within Leonardo's lifetime, his extraordinary powers of invention, his "outstanding physical beauty", "infinite grace", "great strength and generosity", "regal spirit and tremendous breadth of mind" as described by Vasari,[50] as well as all other aspects of his life, attracted the curiosity of others. One such aspect is his respect for life evidenced by his vegetarianism and his habit, according to Vasari, of purchasing caged birds and releasing them.[51][52]

Leonardo had many friends who are now renowned either in their fields or for their historical significance. They included the mathematician Luca Pacioli,[53] with whom he collaborated on a book in the 1490s, as well as Franchinus Gaffurius and Isabella d'Este.[citation needed] Leonardo appears to have had no close relationships with women except for his friendship with the two Este sisters, Beatrice and Isabella.[54] He drew a portrait of her while on a journey which took him through Mantua, and which appears to have been used to create a painted portrait, now lost.[10]

Beyond friendship, Leonardo kept his private life secret. His sexuality has been the subject of satire, analysis, and speculation. This trend began in the mid-16th century and was revived in the 19th and 20th centuries, most notably by Sigmund Freud.[55] Leonardo's most intimate relationships were perhaps with his pupils Salai and Melzi. Melzi, writing to inform Leonardo's brothers of his death, described Leonardo's feelings for his pupils as both loving and passionate. It has been claimed since the 16th century that these relationships were of a sexual or erotic nature. Court records of 1476, when he was aged twenty-four, show that Leonardo and three other young men were charged with sodomy in an incident involving a well-known male prostitute. The charges were dismissed for lack of evidence, and there is speculation that since one of the accused, Lionardo de Tornabuoni, was related to Lorenzo de' Medici, the family exerted its influence to secure the dismissal.[56] Since that date much has been written about his presumed homosexuality and its role in his art, particularly in the androgyny and eroticism manifested in John the Baptist and Bacchus and more explicitly in a number of erotic drawings.[57]

Assistants and pupils

Gian Giacomo Caprotti da Oreno, nicknamed Salai or Il Salaino ("The Little Unclean One" i.e., the devil), entered Leonardo's household in 1490. After only a year, Leonardo made a list of his misdemeanours, calling him "a thief, a liar, stubborn, and a glutton", after he had made off with money and valuables on at least five occasions and spent a fortune on clothes.[59] Nevertheless, Leonardo treated him with great indulgence, and he remained in Leonardo's household for the next thirty years.[60] Salai executed a number of paintings under the name of Andrea Salai, but although Vasari claims that Leonardo "taught him a great deal about painting",[37] his work is generally considered to be of less artistic merit than others among Leonardo's pupils, such as Marco d'Oggione and Boltraffio. In 1515, he painted a nude version of the Mona Lisa, known as Monna Vanna.[61] Salai owned the Mona Lisa at the time of his death in 1525, and in his will it was assessed at 505 lire, an exceptionally high valuation for a small panel portrait.[62]

In 1506, Leonardo took on another pupil, Count Francesco Melzi, the son of a Lombard aristocrat, who is considered to have been his favourite student. He travelled to France with Leonardo and remained with him until Leonardo's death.[10] Melzi inherited the artistic and scientific works, manuscripts, and collections of Leonardo and administered the estate.

Painting

Annunciation (1475–1480)—Uffizi, is thought to be Leonardo's earliest complete work.

Despite the recent awareness and admiration of Leonardo as a scientist and inventor, for the better part of four hundred years his fame rested on his achievements as a painter and on a handful of works, either authenticated or attributed to him that have been regarded as among the masterpieces.[63]

These paintings are famous for a variety of qualities which have been much imitated by students and discussed at great length by connoisseurs and critics. Among the qualities that make Leonardo's work unique are the innovative techniques that he used in laying on the paint, his detailed knowledge of anatomy, light, botany and geology, his interest in physiognomy and the way in which humans register emotion in expression and gesture, his innovative use of the human form in figurative composition, and his use of the subtle gradation of tone. All these qualities come together in his most famous painted works, the Mona Lisa, the Last Supper and the Virgin of the Rocks.[64]

Early works

Leonardo's early works begin with the Baptism of Christ painted in conjunction with Verrocchio. Two other paintings appear to date from his time at the workshop, both of which are Annunciations. One is small, 59 centimetres (23 in) long and 14 centimetres (5.5 in) high. It is a "predella" to go at the base of a larger composition, in this case a painting by Lorenzo di Credi from which it has become separated. The other is a much larger work, 217 centimetres (85 in) long.[65] In both these Annunciations, Leonardo used a formal arrangement, such as in Fra Angelico's two well known pictures of the same subject, of the Virgin Mary sitting or kneeling to the right of the picture, approached from the left by an angel in profile with rich flowing garment, raised wings and bearing a lily. Although previously attributed to Ghirlandaio, the larger work is now generally attributed to Leonardo.[66]

In the smaller picture Mary averts her eyes and folds her hands in a gesture that symbolised submission to God's will. In the larger picture, however, Mary is not submissive. The girl, interrupted in her reading by this unexpected messenger, puts a finger in her bible to mark the place and raises her hand in a formal gesture of greeting or surprise.[42] This calm young woman appears to accept her role as the Mother of God not with resignation but with confidence. In this painting the young Leonardo presents the humanist face of the Virgin Mary, recognising humanity's role in God's incarnation.[nb 20]

Paintings of the 1480s

Virgin of the Rocks, Louvre, demonstrates Leonardo's interest in nature.

In the 1480s Leonardo received two very important commissions and commenced another work which was also of ground-breaking importance in terms of composition. Two of the three were never finished, and the third took so long that it was subject to lengthy negotiations over completion and payment. One of these paintings is that of St. Jerome in the Wilderness. Bortolon associates this picture with a difficult period of Leonardo's life, as evidenced in his diary: "I thought I was learning to live; I was only learning to die."[10]

Although the painting is barely begun, the composition can be seen and it is very unusual.[nb 21] Jerome, as a penitent, occupies the middle of the picture, set on a slight diagonal and viewed somewhat from above. His kneeling form takes on a trapezoid shape, with one arm stretched to the outer edge of the painting and his gaze looking in the opposite direction. J. Wasserman points out the link between this painting and Leonardo's anatomical studies.[68] Across the foreground sprawls his symbol, a great lion whose body and tail make a double spiral across the base of the picture space. The other remarkable feature is the sketchy landscape of craggy rocks against which the figure is silhouetted.

The daring display of figure composition, the landscape elements and personal drama also appear in the great unfinished masterpiece, the Adoration of the Magi, a commission from the Monks of San Donato a Scopeto. It is a complex composition, of about 250 x 250 centimetres. Leonardo did numerous drawings and preparatory studies, including a detailed one in linear perspective of the ruined classical architecture which makes part of the backdrop to the scene. But in 1482 Leonardo went off to Milan at the behest of Lorenzo de' Medici in order to win favour with Ludovico il Moro, and the painting was abandoned.[9][66]

The third important work of this period is the Virgin of the Rocks which was commissioned in Milan for the Confraternity of the Immaculate Conception. The painting, to be done with the assistance of the de Predis brothers, was to fill a large complex altarpiece, already constructed.[69] Leonardo chose to paint an apocryphal moment of the infancy of Christ when the infant John the Baptist, in protection of an angel, met the Holy Family on the road to Egypt. In this scene, as painted by Leonardo, John recognizes and worships Jesus as the Christ. The painting demonstrates an eerie beauty as the graceful figures kneel in adoration around the infant Christ in a wild landscape of tumbling rock and whirling water.[70] While the painting is quite large, about 200 × 120 centimetres, it is not nearly as complex as the painting ordered by the monks of St Donato, having only four figures rather than about fifty and a rocky landscape rather than architectural details. The painting was eventually finished; in fact, two versions of the painting were finished, one which remained at the chapel of the Confraternity and the other which Leonardo carried away to France. But the Brothers did not get their painting, or the de Predis their payment, until the next century.[16][28]

Paintings of the 1490s

Leonardo's most famous painting of the 1490s is The Last Supper, painted for the refectory of the Convent of Santa Maria della Grazie in Milan. The painting represents the last meal shared by Jesus with his disciples before his capture and death. It shows specifically the moment when Jesus has just said "one of you will betray me". Leonardo tells the story of the consternation that this statement caused to the twelve followers of Jesus.[16]

The novelist Matteo Bandello observed Leonardo at work and wrote that some days he would paint from dawn till dusk without stopping to eat and then not paint for three or four days at a time.[71] This was beyond the comprehension of the prior of the convent, who hounded him until Leonardo asked Ludovico to intervene. Vasari describes how Leonardo, troubled over his ability to adequately depict the faces of Christ and the traitor Judas, told the Duke that he might be obliged to use the prior as his model.[72]

When finished, the painting was acclaimed as a masterpiece of design and characterisation,[73] but it deteriorated rapidly, so that within a hundred years it was described by one viewer as "completely ruined".[74] Leonardo, instead of using the reliable technique of fresco, had used tempera over a ground that was mainly gesso, resulting in a surface which was subject to mold and to flaking.[75] Despite this, the painting has remained one of the most reproduced works of art, countless copies being made in every medium from carpets to cameos.

Paintings of the 1500s

Mona Lisa or La Gioconda (1503–1505/1507)—Louvre, Paris, France

Among the works created by Leonardo in the 16th century is the small portrait known as the Mona Lisa or "la Gioconda", the laughing one. In the present era it is arguably the most famous painting in the world. Its fame rests, in particular, on the elusive smile on the woman's face, its mysterious quality brought about perhaps by the fact that the artist has subtly shadowed the corners of the mouth and eyes so that the exact nature of the smile cannot be determined. The shadowy quality for which the work is renowned came to be called "sfumato" or Leonardo's smoke. Vasari, who is generally thought to have known the painting only by repute, said that "the smile was so pleasing that it seemed divine rather than human; and those who saw it were amazed to find that it was as alive as the original".[76][nb 22]

Other characteristics found in this work are the unadorned dress, in which the eyes and hands have no competition from other details, the dramatic landscape background in which the world seems to be in a state of flux, the subdued colouring and the extremely smooth nature of the painterly technique, employing oils, but laid on much like tempera and blended on the surface so that the brushstrokes are indistinguishable.[nb 23] Vasari expressed the opinion that the manner of painting would make even "the most confident master ... despair and lose heart."[79] The perfect state of preservation and the fact that there is no sign of repair or overpainting is rare in a panel painting of this date.[80]

In the painting Virgin and Child with St. Anne the composition again picks up the theme of figures in a landscape which Wasserman describes as "breathtakingly beautiful"[81] and harkens back to the St Jerome picture with the figure set at an oblique angle. What makes this painting unusual is that there are two obliquely set figures superimposed. Mary is seated on the knee of her mother, St Anne. She leans forward to restrain the Christ Child as he plays roughly with a lamb, the sign of his own impending sacrifice.[16] This painting, which was copied many times, influenced Michelangelo, Raphael, and Andrea del Sarto,[82] and through them Pontormo and Correggio. The trends in composition were adopted in particular by the Venetian painters Tintoretto and Veronese.

Drawings

Leonardo was not a prolific painter, but he was a most prolific draftsman, keeping journals full of small sketches and detailed drawings recording all manner of things that took his attention. As well as the journals there exist many studies for paintings, some of which can be identified as preparatory to particular works such as The Adoration of the Magi, The Virgin of the Rocks and The Last Supper.[83] His earliest dated drawing is a Landscape of the Arno Valley, 1473, which shows the river, the mountains, Montelupo Castle and the farmlands beyond it in great detail.[10][83]

Among his famous drawings are the Vitruvian Man, a study of the proportions of the human body, the Head of an Angel, for The Virgin of the Rocks in the Louvre, a botanical study of Star of Bethlehem and a large drawing (160×100 cm) in black chalk on coloured paper of The Virgin and Child with St. Anne and St. John the Baptist in the National Gallery, London.[83] This drawing employs the subtle sfumato technique of shading, in the manner of the Mona Lisa. It is thought that Leonardo never made a painting from it, the closest similarity being to The Virgin and Child with St. Anne in the Louvre.[84]

Other drawings of interest include numerous studies generally referred to as "caricatures" because, although exaggerated, they appear to be based upon observation of live models. Vasari relates that if Leonardo saw a person with an interesting face he would follow them around all day observing them.[85] There are numerous studies of beautiful young men, often associated with Salai, with the rare and much admired facial feature, the so-called "Grecian profile".[nb 24] These faces are often contrasted with that of a warrior.[83] Salai is often depicted in fancy-dress costume. Leonardo is known to have designed sets for pageants with which these may be associated. Other, often meticulous, drawings show studies of drapery. A marked development in Leonardo's ability to draw drapery occurred in his early works. Another often-reproduced drawing is a macabre sketch that was done by Leonardo in Florence in 1479 showing the body of Bernardo Baroncelli, hanged in connection with the murder of Giuliano, brother of Lorenzo de'Medici, in the Pazzi Conspiracy.[83] With dispassionate integrity Leonardo has registered in neat mirror writing the colours of the robes that Baroncelli was wearing when he died.

Observation and invention

Journals and notes

Renaissance humanism recognized no mutually exclusive polarities between the sciences and the arts, and Leonardo's studies in science and engineering are as impressive and innovative as his artistic work.[16] These studies were recorded in 13,000 pages of notes and drawings, which fuse art and natural philosophy (the forerunner of modern science), made and maintained daily throughout Leonardo's life and travels, as he made continual observations of the world around him.[16]

Leonardo's writings are mostly in mirror-image cursive. The reason may have been more a practical expediency than for reasons of secrecy as is often suggested. Since Leonardo wrote with his left hand, it is probable that it was easier for him to write from right to left.[nb 25]

His notes and drawings display an enormous range of interests and preoccupations, some as mundane as lists of groceries and people who owed him money and some as intriguing as designs for wings and shoes for walking on water. There are compositions for paintings, studies of details and drapery, studies of faces and emotions, of animals, babies, dissections, plant studies, rock formations, whirlpools, war machines, helicopters and architecture.[16]

These notebooks—originally loose papers of different types and sizes, distributed by friends after his death—have found their way into major collections such as the Royal Library at Windsor Castle, the Louvre, the Biblioteca Nacional de España, the Victoria and Albert Museum, the Biblioteca Ambrosiana in Milan which holds the twelve-volume Codex Atlanticus, and British Library in London which has put a selection from its notebook BL Arundel MS 263 online.[86] The Codex Leicester is the only major scientific work of Leonardo's in private hands. It is owned by Bill Gates and is displayed once a year in different cities around the world.

Leonardo's notes appear to have been intended for publication because many of the sheets have a form and order that would facilitate this. In many cases a single topic, for example, the heart or the human fetus, is covered in detail in both words and pictures on a single sheet.[87][nb 26] Why they were not published within Leonardo's lifetime is unknown.[16]

Scientific studies

Leonardo's approach to science was an observational one: he tried to understand a phenomenon by describing and depicting it in utmost detail and did not emphasize experiments or theoretical explanation. Since he lacked formal education in Latin and mathematics, contemporary scholars mostly ignored Leonardo the scientist, although he did teach himself Latin. In the 1490s he studied mathematics under Luca Pacioli and prepared a series of drawings of regular solids in a skeletal form to be engraved as plates for Pacioli's book De Divina Proportione, published in 1509.[16]

It appears that from the content of his journals he was planning a series of treatises to be published on a variety of subjects. A coherent treatise on anatomy was said to have been observed during a visit by Cardinal Louis 'D' Aragon's secretary in 1517.[88] Aspects of his work on the studies of anatomy, light and the landscape were assembled for publication by his pupil Francesco Melzi and eventually published as Treatise on Painting by Leonardo da Vinci in France and Italy in 1651 and Germany in 1724,[89] with engravings based upon drawings by the Classical painter Nicholas Poussin.[citation needed] According to Arasse, the treatise, which in France went into sixty two editions in fifty years, caused Leonardo to be seen as "the precursor of French academic thought on art".[16]

A recent and exhaustive analysis of Leonardo as scientist by Frtijof Capra[90] argues that Leonardo was a fundamentally different kind of scientist from Galileo, Newton and other scientists who followed him. Leonardo's experimentation followed clear scientific method approaches, and his theorising and hypothesising integrated the arts and particularly painting; these, and Leonardo's unique integrated, holistic views of science make him a forerunner of modern systems theory and complexity schools of thought.

Anatomy

Leonardo's formal training in the anatomy of the human body began with his apprenticeship to Andrea del Verrocchio, who insisted that all his pupils learn anatomy. As an artist, he quickly became master of topographic anatomy, drawing many studies of muscles, tendons and other visible anatomical features.

As a successful artist, he was given permission to dissect human corpses at the Hospital of Santa Maria Nuova in Florence and later at hospitals in Milan and Rome. From 1510 to 1511 he collaborated in his studies with the doctor Marcantonio della Torre. Leonardo made over 200 pages of drawings and many pages of notes towards a treatise on anatomy. These papers were left to his heir, Francesco Melzi, for publication, a task of overwhelming difficulty because of its scope and Leonardo's idiosyncratic writing.[91] It was left incomplete at the time of Melzi's death more than fifty years later, with only a small amount of the material on anatomy included in Leonardo's Treatise on painting, published in France in 1632.[16][91] During the time that Melzi was ordering the material into chapters for publication, they were examined by a number of anatomists and artists, including Vasari, Cellini and Albrecht Dürer who made a number of drawings from them.[91]

Leonardo drew many studies of the human skeleton and its parts, as well as muscles and sinews. He studied the mechanical functions of the skeleton and the muscular forces that are applied to it in a manner that prefigured the modern science of biomechanics.[92] He drew the heart and vascular system, the sex organs and other internal organs, making one of the first scientific drawings of a fetus in utero.[83] As an artist, Leonardo closely observed and recorded the effects of age and of human emotion on the physiology, studying in particular the effects of rage. He also drew many figures who had significant facial deformities or signs of illness.[16][83]

Leonardo also studied and drew the anatomy of many animals, dissecting cows, birds, monkeys, bears, and frogs, and comparing in his drawings their anatomical structure with that of humans. He also made a number of studies of horses.

Engineering and inventions

A design for a flying machine, (c. 1488) Institut de France, Paris

During his lifetime Leonardo was valued as an engineer. In a letter to Ludovico il Moro he claimed to be able to create all sorts of machines both for the protection of a city and for siege. When he fled to Venice in 1499 he found employment as an engineer and devised a system of moveable barricades to protect the city from attack. He also had a scheme for diverting the flow of the Arno River, a project on which Niccolò Machiavelli also worked.[93][94] Leonardo's journals include a vast number of inventions, both practical and impractical. They include musical instruments, hydraulic pumps, reversible crank mechanisms, finned mortar shells, and a steam cannon.[10][16]

In 1502, Leonardo produced a drawing of a single span 720-foot (220 m) bridge as part of a civil engineering project for Ottoman Sultan Beyazid II of Constantinople. The bridge was intended to span an inlet at the mouth of the Bosporus known as the Golden Horn. Beyazid did not pursue the project because he believed that such a construction was impossible. Leonardo's vision was resurrected in 2001 when a smaller bridge based on his design was constructed in Norway.[95] On May 17, 2006, the Turkish government decided to construct Leonardo's bridge to span the Golden Horn.[96]

For much of his life, Leonardo was fascinated by the phenomenon of flight, producing many studies of the flight of birds, including his c. 1505 Codex on the Flight of Birds, as well as plans for several flying machines, including a light hang glider and a machine resembling a helicopter.[16] The British television station Channel Four commissioned a documentary Leonardo's Dream Machines, for broadcast in 2003. Leonardo's machines were built and tested according to his original designs.[97] Some of those designs proved a success, whilst others fared less well when practically tested.

Leonardo the legend

Francis I of France receiving the last breath of Leonardo da Vinci, by Ingres, 1818

Within Leonardo's own lifetime his fame was such that the King of France carried him away like a trophy and was claimed to have supported him in his old age and held him in his arms as he died. Interest in Leonardo has never diminished. The crowds still queue to see his most famous artworks, T-shirts bear his most famous drawing, and writers like Vasari continue to marvel at his genius and speculate about his private life and, particularly, about what one so intelligent actually believed in.[16]

Giorgio Vasari, in the enlarged edition of Lives of the Artists, 1568,[98] introduced his chapter on Leonardo da Vinci with the following words:

In the normal course of events many men and women are born with remarkable talents; but occasionally, in a way that transcends nature, a single person is marvellously endowed by Heaven with beauty, grace and talent in such abundance that he leaves other men far behind, all his actions seem inspired and indeed everything he does clearly comes from God rather than from human skill. Everyone acknowledged that this was true of Leonardo da Vinci, an artist of outstanding physical beauty, who displayed infinite grace in everything that he did and who cultivated his genius so brilliantly that all problems he studied he solved with ease.

The continued admiration that Leonardo commanded from painters, critics and historians is reflected in many other written tributes. Baldassare Castiglione, author of Il Cortegiano ("The Courtier"), wrote in 1528: "... Another of the greatest painters in this world looks down on this art in which he is unequalled ..."[99] while the biographer known as "Anonimo Gaddiano" wrote, c. 1540: "His genius was so rare and universal that it can be said that nature worked a miracle on his behalf ...".[100]

The 19th century brought a particular admiration for Leonardo's genius, causing Henry Fuseli to write in 1801: "Such was the dawn of modern art, when Leonardo da Vinci broke forth with a splendour that distanced former excellence: made up of all the elements that constitute the essence of genius ..."[101] This is echoed by A. E. Rio who wrote in 1861: "He towered above all other artists through the strength and the nobility of his talents."[102]

Statue of Leonardo in Amboise

By the 19th century, the scope of Leonardo's notebooks was known, as well as his paintings. Hippolyte Taine wrote in 1866: "There may not be in the world an example of another genius so universal, so incapable of fulfilment, so full of yearning for the infinite, so naturally refined, so far ahead of his own century and the following centuries."[103] Art historian Bernard Berenson wrote in 1896: "Leonardo is the one artist of whom it may be said with perfect literalness: Nothing that he touched but turned into a thing of eternal beauty. Whether it be the cross section of a skull, the structure of a weed, or a study of muscles, he, with his feeling for line and for light and shade, forever transmuted it into life-communicating values."[104]

The interest in Leonardo's genius has continued unabated; experts study and translate his writings, analyse his paintings using scientific techniques, argue over attributions and search for works which have been recorded but never found.[105] Liana Bortolon, writing in 1967, said: "Because of the multiplicity of interests that spurred him to pursue every field of knowledge ... Leonardo can be considered, quite rightly, to have been the universal genius par excellence, and with all the disquieting overtones inherent in that term. Man is as uncomfortable today, faced with a genius, as he was in the 16th century. Five centuries have passed, yet we still view Leonardo with awe."[10]

Footnotes

  1. ^ This drawing in red chalk is widely (though not universally) accepted as an original self-portrait. The main reason for hesitation in accepting it as a portrait of Leonardo is that, to modern eyes, the subject appears to be of a greater age than Leonardo ever achieved. It is possible that Leonardo drew this picture of himself deliberately aged, specifically for Raphael's portrait of him in The School of Athens.
  2. ^ There are 15 significant artworks which are ascribed, either in whole or in large part, to Leonardo by most art historians. This number is made up principally of paintings on panel but includes a mural, a large drawing on paper and two works which are in the early stages of preparation. There are a number of other works that have also been variously attributed to Leonardo.
  3. ^ Modern scientific approaches to metallurgy and engineering were only in their infancy during the Renaissance.
  4. ^ A number of Leonardo's most practical inventions are displayed as working models at the Museum of Vinci.
  5. ^ His birth is recorded in the diary of his paternal grandfather Ser Antonio, as cited by Angela Ottino della Chiesa in Leonardo da Vinci, and Reynal & Co., Leonardo da Vinci (William Morrow and Company, 1956): "A grandson of mine was born April 15, Saturday, three hours into the night". The date was recorded in the Julian calendar; as it was Florentine time and sunset was 6:40 pm, three hours after sunset would be sometime around 9:40 pm which was still April 14 by modern reckoning. The conversion to the New Style calendar adds nine days; hence Leonardo was born April 23 according to the modern calender.[7]
  6. ^ It has been suggested that Caterina may have been a slave from the Middle East "or at least, from the Mediterranean". According to Alessandro Vezzosi, head of the Leonardo Museum in Vinci, there is evidence that Piero owned a Middle Eastern slave called Caterina. That Leonardo had Middle Eastern blood is claimed to be supported by the reconstruction of a fingerprint as reported by Falconi, Marta (December 12, 2006). "Experts Reconstruct Leonardo Fingerprint". Associated Press (News ed.). USA: Fox. http://www.foxnews.com/wires/2006Dec01/0,4670,LeonardoapossFingerprint,00.html. Retrieved 2010-01-06. . The evidence, as stated in the article, is that 60% of people of Middle Eastern origin share the pattern of whirls found on the reconstructed fingerprint. The article also states that the claim is refuted by Simon Cole, associate professor of criminology, law and society at the University of California at Irvine: "You can't predict one person's race from these kinds of incidences, especially if looking at only one finger."
  7. ^ The "diverse arts" and technical skills of Medieval and Renaissance workshops are described in detail in the 12th century text On Divers Arts by Theophilus Presbyter and in the early 15th century text Il Libro Dell'arte O Trattato Della Pittui by Cennino Cennini.
  8. ^ That Leonardo joined the guild before this time is deduced from the record of payment made to the Compagnia di San Luca in the company's register, Libro Rosso A, 1472–1520, Accademia di Belle Arti.[9]
  9. ^ This work is now in the collection of the Uffizi, Drawing No. 8P.
  10. ^ Homosexual acts were illegal in Renaissance Florence.
  11. ^ Verrocchio's statue of Bartolomeo Colleoni was not cast until 1488, after his death, and after Leonardo had already begun work on the statue for Ludovico.
  12. ^ In 2005, the studio was rediscovered during the restoration of part of a building occupied for 100 years by the Department of Military Geography.[30]
  13. ^ Both works are lost. While the entire composition of Michelangelo's painting is known from a copy by Aristotole da Sangallo, 1542.[31] Leonardo's painting is only known from preparatory sketches and several copies of the centre section, of which the best known, and probably least accurate, is by Peter Paul Rubens.[32]
  14. ^ D'Oggione is known in part for his contemporary copies of the Last Supper.
  15. ^ It is unknown for what occasion the mechanical lion was made but it is believed to have greeted the king at his entry into Lyon and perhaps was used for the peace talks between the French king and Pope Leo X in Bologna. A conjectural recreation of the lion has been made and is on display in the Museum of Bologna.[38]
  16. ^ Clos Lucé, also called Cloux, is now a public museum.
  17. ^ On the day of Leonardo's death, a royal edict was issued by the king at Saint-Germain-en-Laye, a two-day journey from Clos Lucé. This has been taken as evidence that King François cannot have been present at Leonardo's deathbed. However, White in Leonardo: The First Scientist points out that the edict was not signed by the king.
  18. ^ This was a charitable legacy as each of the sixty paupers would have been awarded an established mourner's fee in the terms of Leonardo's will.
  19. ^ The black cloak, of good quality material, was a ready-made item from a clothier, with the fur trim being an additional luxury. The possession of this garment meant that Leonardo's house keeper could attend his funeral "respectably" attired at no expense to herself.
  20. ^ Michael Baxandall lists 5 "laudable conditions" or reactions of Mary to the presence and announcement of the angel. These are: Disquiet, Reflection, Inquiry, Submission and Merit. In this painting Mary's attitude does not comply with any of the accepted traditions.[67]
  21. ^ The painting, which in the 18th century belonged to Angelica Kauffmann, was later cut up. The two main sections were found in a junk shop and cobbler's shop and were reunited.[68] It is probable that outer parts of the composition are missing.
  22. ^ Whether or not Vasari had seen the Mona Lisa is the subject of debate. The opinion that he had not seen the painting is based mainly on the fact that he describes the Mona Lisa as having eyebrows. Daniel Arasse in Leonardo da Vinci discusses the possibility that Leonardo may have painted the figure with eyebrows which were subsequently removed. (They were not fashionable in the mid 16th century.)[16] The analysis of high resolution scans made by Pascal Cotte has revealed that the Mona Lisa had eyebrows and eyelashes which have been subsequently removed.[77]
  23. ^ Jack Wasserman writes of "the inimitable treatment of the surfaces" of this painting.[78]
  24. ^ The "Grecian profile" has a continuous straight line from forehead to nose-tip, the bridge of the nose being exceptionally high. It is a feature of many Classical Greek statues.
  25. ^ Left-handed writers using a split nib or quill pen experience difficulty pushing the pen from left to right across the page.
  26. ^ This method of organisation minimises of loss of data in the the case of pages being mixed up or destroyed.
