[sc. The Theseia is] a certain festival celebrated amongst the Athenians. For after Theseus gave the Athenians their democracy, a certain Lykos by false slanders got the hero ostracized. He repaired to Skyros and spent time with Lykomedes, dynast of the island -- who out of jealousy killed him guilefully. But the Athenians suffered a famine and were ordered to avenge Theseus, so they killed Lykomedes, and after bringing the bones [of Theseus] back and constructing the Theseion they honored him equal to a god. And there were doles and feasts at the Theseia. And a festival was celebrated for him, since he brought Attica together, when it had previously been inhabited as [separate] villages.[1]
This Theseus, son of Aigeus, an Athenian, made a display of many [wondrous] deeds. For he pacified all the land from Troizen as far as Athens, which had been full of pirates, by killing Kerkyon and Skiron and Sinnis the pine-bender[2] and Periphantos the club-bearer, whose club he himself later carried, and Prokroustes the killer of guests. He also mastered the Amazon host when it came to Athens, and after marrying their queen he got [a son] Hippolytos. Then he married Phaidra. He also waged war against the Centaurs on the side of the Lapiths and King Perithous,[3] and other such things.
