The frontispiece of an Adelard of Bath Latin translation of Euclid's Elements, c. 1309–1316; the oldest surviving Latin translation of the Elements is a 12th century work by Adelard, which translates to Latin from the Arabic.[1]

Adelard of Bath (Latin: Adelardus Bathensis) (c. 1080 – c. 1152) was a 12th century English scholar. He is known both for his original works and for translating many important Arabic scientific works of astrology, astronomy, philosophy and mathematics into Latin, including ancient Greek texts which only existed in Arabic form, which were then introduced to Europe. He studied at Tours, taught for a time at Laon, then travelled to Southern Italy, Syracuse in Sicily, and Antioch in Asia Minor. He had settled in Bath in England by 1122.[2]

Background

One of the first to introduce the Indian number system to Europe. He wrote a book called "Liber algorismi de Numero Indorum". His highly regarded original works, the Quaestiones Naturales (Natural Questions), the De Eodem et Diverso (On the Same and the Different) and a shorter treatise On Birds were addressed to his nephew in the form of dialogue or correspondence. In the Natural Questions he indicates he is responding to his nephews' desire to know what Adelard had learned "from the studies of the Arabs," while in the others he passes on Greek and English learning.[3] Adelard also displays original thought of a scientific bent, raising the question of the shape of the Earth (he believed it round) and the question of how it remains stationary in space, and also the interesting question of how far a rock would fall if a hole were drilled through the earth and a rock dropped in it, see center of gravity. He theorized that matter could not be destroyed, see Law of conservation of matter and was also interested in the question of why water experiences difficulty flowing out of a container that has been turned upside down, see atmospheric pressure and vacuum. Many of the other questions addressed reflect the popular culture of the times. In On the Same and the Different he contrasts the virtues of the seven liberal arts with worldly interests.

He translated the astronomical tables of al-Khwarizmi and the Introduction to Astrology of Abū Ma'shar. He wrote a short treatise on the abacus (Regulae abaci). He wrote a treatise on the astrolabe. Euclid's Elements had been lost to Christian Europe until Adelard, around 1120, disguised himself as a Muslim student in order to obtain a copy in Muslim Córdoba.[4] He translated Euclid's Elements into Latin from an Arabic translation of the Greek original. Johannes Campanus probably had access to Adelard's translation of Elements, and it is Campanus' edition that was first published in Venice in 1482 after the invention of the printing press. It became the chief text-book of the mathematical schools of Europe.
