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 and lust, 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. The writers of Megara, however, in contradiction to the received report, and, as Simonides expresses it, "fighting with all antiquity," contend that Sciron was neither a robber nor doer of violence, but a punisher of all such, and the relative and friend of good and just men; for Aeacus, they say, was ever esteemed a man of the greatest sanctity of all the Greeks; and Cychreus, the Salaminian, was honoured at Athens with divine worship; and the virtues of Peleus and Telamon were not unknown to any one. Now Sciron was son-in-law to Cychreus, father-in-law to Aeacus, and grandfather to Peleus and Telamon, who were both of them sons of Endeis, the daughter of Sciron and Chariclo; it was not probable, therefore, that the best of men should make these alliances with one who was worst, giving and receiving mutually what was of greatest value and most dear to them. Theseus, by their account, did not slay Sciron in his first journey to Athens, but afterwards, when he took Eleusis, a city of the Megarians, having circumvented Diocles, the governor. Such are the contradictions in this story. 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 in the punishment of evil men, who underwent the same violence from him which they had inflicted upon others, justly suffering after the 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, labouring under the same distemper; for Medea, having fled from Corinth, and promised Aegeus to make him, by her art, capable of having children, was living with him. She first was 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 recognising 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; and it is said, that when the cup fell, the poison was spilt there where now is the enclosed space in the Delphinium; for in that place stood Aegeus's house, and the figure of Mercury on the east side of the temple is called the Mercury of Aegeus's gate.
The sons of Pallas, who before 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, an 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 Pallantidae. He immediately fell upon those that lay in ambuscade, and cut them all off; upon tidings of which Pallas and his company fled and were dispersed.
