Phaea
The name of the sow of Crommyon, which ravaged the neighbourhood, and was slain by Theseus. ( Theseus From Plutarch's Lives)
From Smith's Dictionary of Greek and Roman Biography and MythologyThe 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.
[1.1] I. Third, he slew at Crommyon the sow that was called Phaea after the old woman who bred it; that sow, some say, was the offspring of Echidna and Typhon.
From Description of Greece by Pausanias Book 2
[2.1.3] In the Corinthian territory is also the place called Cromyon from Cromus the son of Poseidon. Here they say that Phaea was bred; overcoming this sow was one of the traditional achievements of Theseus. Farther on the pine still grew by the shore at the time of my visit, and there was an altar of Melicertes. At this place, they say, the boy was brought ashore by a dolphin; Sisyphus found him lying and gave him burial on the Isthmus, establishing the Isthmian games in his honor.
