The Crommyonian sow, which they called Phaea, was a savage and formidable wild beast, by no means an enemy to be despised. Theseus killed her, going out of his way on purpose to meet and engage her, so that he might not seem to perform all his great exploits out of mere necessity; being also of opinion that it was the part of a brave man to chastise villainous and wicked men when attacked by them, but to seek out and overcome the more noble wild beasts. Others relate that Phaea was a woman, a robber full of cruelty, that lived in Crommyon, and had the name of Sow given her from the foulness of her life and manners, and afterwards was killed by Theseus. He slew also Sciron, upon the borders of Megara, casting him down from the rocks, being, as most report, a notorious robber of all passengers, and, as others add, accustomed out of insolence and wantonness, to stretch forth his feet to strangers, commanding them to wash them, and then while they did it, with a kick to send them down the rock into the sea. In Eleusis he killed Cercyon, the Arcadian, in a wrestling match. And going on a little farther, in Erineus, he slew Damastes, otherwise called Procrustes, forcing his body to the size of his own bed, as he himself was used to do with all strangers; this he did in imitation of Hercules, who always returned upon his assailants the same sort of violence that they offered to him; sacrificed Busiris, killed Antaeus in wrestling, and Cycnus in single combat, and Termerus by breaking his skull in pieces (whence, they say, comes the proverb of "a Termerian mischief"), for it seems Termerus killed passengers that he met by running with his head against them. And so also Theseus proceeded with the same violence from which they had inflicted upon others, justly suffering after the same manner of their own injustice. As he went forward on his journey, and was come as far as the River Cephisus, some of the race of the Phytalidae met him and saluted him, and upon his desire to use the purifications, then in custom, they performed them with all the usual ceremonies, and having offered propitiatory sacrifices to the gods, invited him and entertained him at their house, a kindness which, in all his journey hitherto, he had not met.
