Plutarch, Theseus
Bernadotte Perrin, Ed.

He also slew Sciron on the borders of Megara, by hurling him down the cliffs. Sciron robbed the passers by, according to the prevalent tradition; but as some say, he would insolently and wantonly thrust out his feet to strangers and bid them wash them, and then, while they were washing them, kick them off into the sea. [2] Megarian writers, however, taking issue with current report, and, as Simonides¹ expresses it, ‘waging war with antiquity,’ say that Sciron was neither a violent man nor a robber, but a chastiser of robbers, and a kinsman and friend of good and just men. For Aeacus, they say, is regarded as the most righteous of Hellenes, and Cychreus the Salaminian has divine honors at Athens, and the virtues of Peleus and Telamon are known to all men. [3] Well, then, Sciron was a son-in-law of Cychreus, father-in-law of Aeacus, and grandfather of Peleus and Telamon, who were the sons of Endeis, daughter of Sciron and Chariclo. It is not likely, then, they say, that the best of men made family alliances with the basest, receiving and giving the greatest and most valuable pledges. It was not, they say, when Theseus first journeyed to Athens, but afterwards, that he captured Eleusis from the Megarians, having circumvented Diocles its ruler, and slew Sciron. Such, then, are the contradictions in which these matters are involved.
