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.
On the eighth day of Cronius, now called Hecatombaeon, he arrived at Athens, where he found the public affairs full of all confusion, and divided into parties and factions. Aegeus also, and his whole private family, laboring under the same distemper; for Medea, having fled from Corinth, was living with him. She was first aware of Theseus, whom as yet Aegeus did not know, and he being in years, full of jealousies and suspicions, and fearing everything by reason of the faction that was then in the city, she easily persuaded him to kill him by poison at a banquet, to which he was to be invited as a stranger. He, coming to the entertainment, thought it not fit to discover himself at once, but, willing to give his father the occasion of first finding him out, the meat being on the table, he drew his sword as if he designed to cut with it; Aegeus, at once recognizing the token, threw down the cup of poison, and, questioning his son, embraced him, and, having gathered together all his citizens, owned him publicly before them, who, on their part, received him gladly for the fame of his greatness and bravery.
The sons of Pallas, who were quiet, upon expectation of recovering the kingdom after Aegeus's death, who was without issue, as soon as Theseus appeared and was acknowledged the successor, highly resenting that Aegeus first, as adopted son only of Pandion, and not at all related to the family of Erechtheus, should be holding the kingdom, and that after him, Theseus, a visitor and stranger, should be destined to succeed to it, broke out into open war. And, dividing themselves into two companies, one part of them marched openly from Sphettus, with their father, against the city; the other, hiding themselves in the village of Gargettus, lay in ambush, with a design to set upon the enemy on both sides. They had with them a crier of the township of Agnus, named Leos, who discovered to Theseus all the designs of the Pallentidae. He immediately fell upon those that lay in amuscade, and cut them all off; upon tidings of which Pallas and his company fled and were dispersed.
From hence they say is derived the custom among the people of the township of Pallene to have no marriages or any alliance with the people of Agnus, nor to suffer the criers to pronounce in their proclamations the words used in all other parts of the country, Acouete Leoi (Hear ye people), hating the very sound of Leo, because of the treason of Leos.
Theseus, longing to be in action, and desirous also to make himself popular, left Athens to fight with the bull of Marathon, which did no small mischief to the inhabitants of Tetrapolis. And, having overcome it, he brought it alive in triumph through the city, and afterwards sacrificed it to the Delphian Apollo. The story of Hecale, also, of her receiving and entertaining Theseus in this expedition, seems to be not altogether void of truth; for the townships round about, meeting upon a certain day, used to offer a sacrifice, which they called Hecalesia, to Jupiter Hecaleius, and to pay honor to Hecale, whom, by a diminutive name, they called Hecalene, because she, while entertaining Theseus, who was quite a youth, addressed him, as old people do, with similar endearing diminutives; and having made a vow to Jupiter that he was going to the fight, that, if he returned in safety, she would offer sacrifices in thanks of it, and dying before he came back, she had these honors given her by way of return for her hospitality, by the command of Theseus, as Philochorus tells us.
