IX. Now the wild sow of Krommyon, whom they called Phaia, was no ordinary beast, but a fierce creature and hard to conquer. This animal he turned out of his way to destroy, that it might not be thought that he performed his exploits of necessity. Besides, he said, a brave man need only punish wicked men when they came in his way, but that in the case of wild beasts he must himself seek them out and attack them. Some say that Phaia was a murderous and licentious woman who carried on brigandage at Krommyon, and was called a sow from her life and habits, and that Theseus put her to death. X. Before coming to Megara he slew Skeiron by flinging him down a precipice into the sea, so the story runs, because he was a robber, but some say that from arrogance he used to hold out his feet to strangers and bid them wash them, and that then he kicked the washers into the sea. But Megarian writers, in opposition to common tradition, and, as Simonides says, "warring with all antiquity," say that Skeiron was not an arrogant brigand, but repressed brigandage, loved those who were good and just, and was related to them. For, they point out, Aeakus is thought to have been the most righteous of all the Greeks, and Kychreus of Salamis was worshipped as a god, and the virtue of Peleus and Telamon is known to all. Yet Skeiron was the son-in-law of Kychreus, and father-in-law of Aeakus, and grandfather of Peleus and Telamon, who were both of them sons of Endeis, the daughter of Skeiron and his wife Chariklo. It is not then reasonable to suppose that these, the noblest men of their time, would make alliances with a malefactor, and give and receive from him what they prized most dearly. But they say that Theseus slew Skeiron, not when he first went to Athens, but that afterwards he took the town of Eleusis which belonged to the Megarians, by dealing treacherously with Diokles, who was the chief magistrate there, and that on that occasion he killed Skeiron. This is what tradition says on both sides. XI. At Eleusis Theseus overcame Kerkyon of Arcadia in wrestling and killed him, and after journeying a little farther he killed Damastes, who was surnamed Prokroustes, by compelling him to fit his own body to his bed, just as he used to fit the bodies of strangers to it. This he did in imitation of Herakles; for he used to retort upon his aggressors the same treatment which they intended for him. Thus Herakles offered up Busiris as a sacrifice, and overcame Antaeus in wrestling, and Kyknus in single combat, and killed Termerus by breaking his skull. This is, they say, the origin of the proverb, "A Termerian mischief," for Termerus, it seems, struck passers-by with his head, and so killed them. So also did Theseus sally forth and chastise evildoers, making them undergo the same cruelties which they practised on others, thus justly punishing them for their crimes in their own wicked fashion.
