Astronomy
Philosopher Empedocles [b. Akragas, Sicily, c. 492 bce, d. Mount Etna, c. 432 bce] proposes that eclipses of the Sun are caused by the Moon coming between Earth and the Sun. See also 520 bce Astronomy.
Greek philosopher Oenopides [b. Chios, Greece, c. 490 bce, d. c. 420 bce] calculates the angle that Earth is tipped with respect to the plane of its orbit (an angle apparent to anyone who regularly watches the stars -- it is not necessary to assume that Earth travels in a path around the Sun). His value of 24° is only half a degree from the presently accepted value of 23.5° and will be used until Eratosthenes refines it to the more precise value.
MaterialsAn ironworking industry develops in Great Britain. See also 500 bce Materials.
Although early Greek temples were constructed of sun-baked brick and wood, marble eventually replaces these materials, although at first the marble is treated in much the same way as the earlier brick -- stuccoed over and painted. About this time an excellent source of marble is found on Mount Pentelicus, a short distance north of Athens, enabling Greek builders to construct the famous white marble buildings and statues of the Acropolis. Because such marble can be cut in beams up to 4.5 m (15 ft) long, Greek architects do not need to utilize arches, corbels, or domes on roofs, sticking mostly with post and lintel construction.
Greek historian Herodotus of Halicarnassus (Turkey) [b. 484 bce, d. c. 425 bce] explores the Middle East, Babylon, and Persia about this time and gives the first description of cotton, which he finds in India. See also 3000 bce Food & agriculture.
MathematicsThe Greeks develop a method of writing numbers based on letters of the alphabet. See also 3100 bce Mathematics.
Medicine & healthEmpedocles recognizes that the heart is the center of the system of blood vessels, but wrongly concludes that this organ must also be the seat of the emotions, a notion that was accepted by many later Greek writers and that has persisted in folk tradition ever since. See also 275 bce Medicine & health.
PhysicsGreek philosopher Protagoras [b. Abdera (Spain), c. 490 bce, d. c. 420 bce] believes that sense perceptions are all that exist, so that reality may be different from one person to another. See also 440 bce Physics.
Empedocles of Akragas introduces a system in which fire, air, earth, and water are the elemental substances that can undergo change through the action of two opposing forces, love and strife. See also 475 bce Physics. (See essay.)
Greek philosopher Leucippus of Miletus (Turkey) [b. c. 480 bce, d. c. 425 bce] introduces the first idea of the atom, an indivisible unit of matter. See also 430 bce Physics.

459 BC
By place
Persian Empire
- The Jewish priest Ezra assembles and leads a band of approximately 5,000 Jews from Babylon to Jerusalem.
Greece
- Athens allies itself with the city state of Megara which is under pressure from Corinth. This alliance leads to war between Corinth and Athens. The first battle of the war, at Haliesis in the Gulf of Argolis, results in a Corinthian victory, but the next battle, at Cecryphalea (modern Angistrion), goes Athens' way.
Roman Republic
- The Aequi occupy Tusculum. In response to the threat, the Roman Senate decide to send an army to help the allied city, under the command of consul Lucius Cornelius Maluginensis. In addition, the consul Fabius Vibulanus, who was at that point besieging Antium, moves his forces to attack Tusculum. The Tusculans are able to recapture their city. A truce is then arranged with the Aequi.
Sicily
- The Sicilian town of Morgantina is destroyed by Ducetius, hellenised leader of the Siculi (according to Diodorus Siculus).
458 BC

- The Athenians start constructing the Long Walls to protect the route from their city to the port city of Piraeus.
- Aegina joins the Peloponnesian alliance, but their combined fleet is defeated by the Athenians in the Battle of Aegina. The Athenians, under the command of Leosthenes, land on the island of Aegina and besiege and defeat the city. Aegina is forced to pay tribute to Athens.
Roman Republic
- The Roman general Lucius Quinctius Cincinnatus is summoned by the Roman Senate to defend the city from attack by the approaching Aequi. He is named dictator of Rome for six months. He goes on to defeat the enemy in a single day at the Battle of Mons Algidus and celebrates a triumph in Rome. Sixteen days after the battle, he resigns his dictatorship and returns to his farm.

Persian Empire
- Artaxerxes I decrees that the city government of Jerusalem be re-established.[1]
Greece
- Athens, the leader of the Delian League, comes into conflict with Corinth and its ally Sparta (leader of the Peloponnesian League) over Megara. Nicodemes of Sparta, regent for King Pleistoanax, leads an army of 11,500 hoplites into Boeotia to help Thebes put down a rebellion by Phocis.
- Athenian forces block the routes back to the Peloponnese, so the Spartans decide to remain in Boeotia and await the Athenian attack. The Athenians and their allies, with 14,000 men under the command of Myronides, meet the Spartans at Battle of Tanagra. The Spartans win the battle, but they lose many men and so are unable to follow up on their victory.
- The Athenians regroup after the battle and march into Boeotia. Led by Myronides, the Athenians defeat the Boeotians in the Battle of Oenophyta, and then destroy the walls of Tanagra and ravage Locris and Phocis.
- Athens goes on to defeat Aegina later in the year, and to finish the construction of the Long Walls to the Athenian port of Piraeus (an action opposed by Sparta).
- Boeotia, Phocis and Opuntian Locris become members of the Delian League. Athens now has enrolled in the Delian League all the Boeotian cities except Thebes. Aegina is forced to become a member of the League. It is assessed, with Thasos, for a yearly contribution to the League of 30 talents.
- The Zeus Temple at Olympia is completed. The forty-foot statue of Zeus inside it becomes one of the Seven Wonders of the Ancient World.
456 BC

- The temple of Zeus in Olympia is finished.
455 BC
By place
Greece
- Athens, under Athenian general Tolmides, sends 100 ships around the Peloponnesus and they set fire to the Spartan naval base at Gythion. As a result, Athens gains the agreement of the Achaean cities to join the Delian League. Athenian forces then go on to attack the Spartan allies on the Corinthian Gulf. Athens is now able to confine Sparta to the southern Peloponnesus.
- The Athenians suffer a severe defeat in Egypt at the hands of the Persians. After being cut off in the Nile Delta, the Athenian fleet is defeated, and the Athenian army retreats across the Sinai Desert to Byblos before its remnants are rescued. The Egyptian rebel Inaros is crucified by the Persians. The Athenians decide against any further military activity in Egypt.

By place
Greece
- Athenian general Cimon sails to Cyprus with two hundred triremes of the Delian League. From there, he sends sixty ships to Egypt to help the Egyptians under Amyrtaeus, who is fighting the Persians in the Nile Delta. Cimon uses the remaining ships to aid an uprising of the Cypriot Greek city-states against Persian control of the island. Cimon lays siege to the Persians stronghold of Citium on the south west coast of Cyprus. However, the siege fails and Cyprus remains under Phoenician (and Persian) control.
- During the siege Cimon dies and the command of the fleet is given to Anaxicrates, who leaves Citium to engage the Phoenician fleet in the Battle of Salamis in Cyprus. The Greek fleet is victorious against the Persians and their allies and then returns to Athens.
- The Athenians reduce the tribute due from their subject city-states (ie members of the Delian League), and each city is allowed to issue its own coinage.

This second decemviri adds two more headings to their predecessor's ten, completing the Law of the Twelve Tables (Lex Duodecim Tabularum), which will form the centrepiece of Roman law for the next several centuries. Nevertheless, this Decemvirate's rule becomes increasingly violent and tyrannical.
Sicily
- After minor preliminary successes (including the capture of Inessa from its Greek colonists), Ducetius, a Hellenised leader of the Siculi, an ancient people of Sicily, is decisively defeated by the combined forces of Syracuse and Acragas. Ducetius flees to exile in Corinth.
