Sci & Tech Chronology: In the year 432 bce

Astronomy

Meton of Athens [b. Athens, c. 440 bce] develops what we now call the Metonic cycle, the (approximately) 19-year period in which the motions of the Sun and Moon seem to come together from our vantage point on Earth. This period can be used to predict eclipses and forms the basis of the Greek and Jewish calendars. See also 475 bce Astronomy.

Construction

Construction of the Parthenon is completed shortly before the death of Pericles. See also 438 bce Construction; 1687 ce Construction.

Earth science

Empedocles, according to legend, jumps into a volcano's crater after failing to be taken into the heavens to become a god, which he had predicted would happen. See also 79 ce Earth science.

Events

By place

Greece

  • Sparta calls and hosts a conference of the Peloponnesian League. The conference is attended by Athenian representatives as well as members of the League. Following arguments by Corinth against Athens, a majority of the League members vote to declare that the Athenians had broken the peace.
  • The Athenian admiral, Phormio, continues the siege of Potidaea by blocking the entrance to the Gulf of Corinth. Meanwhile an Athenian fleet, led by Archestratus, sails for Potidaea. However, instead of attacking Potidaea, they attack the Macedonians under Perdiccas II, who have allied with the Potidaeans. The Athenians capture Therma (modern Thessalonica) and then go on to besiege Pydna. However, as the Athenians are besieging Pydna, they receive news that Corinth has sent a force under the command of Aristeus to support Potidaea. In response, Athens sends more troops and ships under the command of Hipponicus. The combined Athenian force sails to Potidaea and lands there. In the ensuing Battle of Potidaea, the Athenians are victorious against Corinth and its allies.

Astronomy

  • Meton of Athens, a Greek mathematician and astronomer, calculates accurately the comparative chronology of the solar and lunar cycles. As a result, he introduces the 19-year Metonic cycle into the Athenian calendar as a method of calculating dates. Working with Euctemon, he observes the summer solstice on 27 June.
