Physics

The Greek philosopher Plato founds his school, the Academy, at Athens and begins his trilogy, Timaeus, Critias, and Hemocrates, finishing only Timaeus, in which he expounds his theory of four elements -- earth, water, air, and fire -- and hints at a fifth element, the ether. See also 450 bce Physics. (See biography.)

Plato is said to build an "alarm clock" to wake up his students. According to one account, it is a clepsydra that consists of a vessel slowly filling with water and in which floats a bowl with lead balls. When the bowl reaches the rim of the vessel, it topples over and the lead balls fall on a copper plate. Another reconstruction has Plato using two jars and a siphon. Water slowly empties through the night until it reaches the siphon, whereupon it swiftly is transported via the siphon to the other jar. Water rising in the other jar forces air through a whistle, sounding the alarm. See also 1380 bce Tools.

Events

By place

Greece

  • Antalcidas, commander of the Spartan navy, actively assists Persia against Athens. After escaping from the Athenian blockade at Abydos, he attacks and defeats a small Athenian force, then joins his fleet with a supporting fleet sent from Syracuse. With this force, which is soon further augmented with ships supplied by the Persian satraps of the region, he sails to the Hellespont, where he is in a position to cut off the trade routes that bring grain to Athens.
  • The Persians, unnerved by some of Athens' actions, including supporting King Evagoras of Cyprus and Pharaoh Hakor of Egypt (both of whom are at war with Persia), decide that their policy of weakening Sparta by supporting its enemies is no longer wise. So Antalcidas enters into negotiations with the Persian satrap Tiribazus and reaches an agreement under which the Persians will enter into the war on the Spartan side if the allies refuse to make peace.
  • With Antalcidas' Spartan fleet in control of the Hellespont, Sparta deprives Athens of her Bosporus trade and tolls. The Athenians, mindful of being in a similarly serious situation as when defeated in the Peloponnesian War less than two decades before and facing Persian intervention on Sparta's side, are thereby ready to make peace.
  • With the support of the Persian King Artaxerxes II, King Agesilaus II of Sparta concludes "the King's Peace" (or the Peace of Antalcidas, after the Spartan envoy and commander) with Greek allied forces in a manner favourable to Sparta. Under the Peace, all the Asiatic mainland and Cyprus remain under Persian control, Lemnos, Imbros, and Scyros remain Athenian dependencies, and all the other Greek states are to receive autonomy. By the King's Peace, the Persians become key players in Greek politics.
  • Under the threat of Spartan intervention, Thebes disbands its league, and Argos and Corinth end their shared government. Corinth, deprived of its strong ally, is incorporated back into Sparta's Peloponnesian League. After eight years of fighting, the Corinthian War is at an end.

Sicily

  • With the aid of the Lucanians, Dionysius I of Syracuse devastates the territories of Thurii, Croton, and Locri in mainland Italy. When Rhegium falls, Dionysius becomes the chief power in Greek Southern Italy. He then turns his attention to the Adriatic.
  • Plato is forced by Dionysius to leave Syracuse after having exercised the right of free speech too broadly. Plato returns to Athens, outside which he founds a school.
