Epimenides

Epimenides of Knossos (Crete) (Greek: Ἐπιμενίδης) was a semi-mythical 7th or 6th century BC Greek seer and philosopher-poet. While tending his father's sheep, he is said to have fallen asleep for fifty-seven years in a Cretan cave sacred to Zeus, after which he reportedly awoke with the gift of prophecy (Diogenes Laertius i. 109–115). Plutarch writes that Epimenides purified Athens after the pollution brought by the Alcmeonidae, and that the seer's expertise in sacrifices and reform of funeral practices were of great help to Solon in his reform of the Athenian state. The only reward he would accept was a branch of the sacred olive, and a promise of perpetual friendship between Athens and Cnossus (Plutarch, Life of Solon, 12; Aristotle, Ath. Pol. 1).
