Sophocles, the son of Sophillus, was a wealthy member of the rural "deme" (small community) of Hippeios Colonus in Attica, which was to become a setting for one of his plays; and he was probably born there, a few years before the Battle of Marathon in 490 BC: the exact year is unclear, but 497/6 is most likely. He was born into a wealthy family (his father was an armour manufacturer), and was highly educated. His first artistic triumph was in 468 BC, when he took first prize in the Dionysia, beating the reigning master of Athenian drama, Aeschylus. According to Plutarch, the victory came under unusual circumstances: instead of following the usual custom of choosing judges by lot, the archon asked Cimon, and the other "strategoi" present, to decide the victor of the contest. Plutarch further contends that, following this loss, Aeschylus soon left for Sicily. Though Plutarch says that this was Sophocles' first production, it is now thought that his first production was probably in 470 BC. "Triptolemus" was probably one of the plays that Sophocles presented at this festival.
