Introduction - Overview
The Crommyonian Sow is the man-killing beast called Phaea that Theseus destroys on his overland journey from Troezen to Athens. Bacchylides already includes the killing among the young hero's famous deeds, while Pseudo-Apollodorus says the sow was named after the old woman who bred it and records a variant genealogy from Typhon and Echidna. Plutarch preserves a rationalised alternative in which Phaea was not an animal at all but a violent female robber nicknamed the Sow. The creature therefore belongs to the same road-clearing cycle as Periphetes, Sinis, Sciron, Cercyon and Procrustes, but remains distinctive because Theseus deliberately seeks out a monstrous animal rather than merely punishing a human criminal.

Crommyonian Sow
Crommyon lay on the Isthmus of Corinth between the Megarian and Corinthian worlds. Ancient writers remembered the district as the home of a destructive sow that killed people and made the countryside dangerous. Its local name, Phaea or Phaia, was also the name of an old woman associated with the animal. Pseudo-Apollodorus says the sow was called after the woman who bred it.
One genealogy makes the sow a child of Typhon and Echidna, attaching it to the same wider monster family as Orthrus, Cerberus and the Chimera. This is explicitly a variant rather than the only account. Other traditions simply treat Phaea as a savage animal of extraordinary size and ferocity.
Theseus meets the sow during the series of adventures that turns his journey to Athens into a deliberate heroic programme. After recovering the sword and sandals left by Aegeus, he chooses the dangerous land route rather than the easier sea journey. He kills Periphetes and Sinis before reaching Crommyon, then continues towards Sciron, Cercyon and Procrustes after the sow's death.
Plutarch emphasises that Theseus goes out of his way to attack the sow because he does not want his reputation to depend only on opponents he is forced to meet. The animal is therefore a chosen test of courage rather than an accidental obstacle. Its death belongs to the public construction of Theseus as a protector who makes the road safer for ordinary travellers.
The sow's story develops several additional branches. Strabo records a tradition making it the mother of the Calydonian Boar, extending the destructive lineage into the Meleager cycle. Plutarch also gives a rationalised story in which Phaea is a female robber whose violent character earns the nickname Sow. Hyginus sometimes calls the creature a boar rather than a sow. These variations change the animal's genealogy or even its species without removing Crommyon and Theseus from the centre of the tradition.
Greek vase painters repeatedly include the sow among Theseus's early deeds. In some scenes the beast charges the hero while an elderly woman stands nearby, visually preserving the tradition of the keeper Phaea. The combination of monster and human attendant helps explain why later writers could move between animal and rationalised human versions of the story.
Summary
The Crommyonian Sow endures as Phaea, the man-killing beast destroyed by Theseus on the road to Athens. Pseudo-Apollodorus links her name to an elderly keeper and records Typhon and Echidna as possible parents, while Plutarch preserves a human robber called Phaea as an alternative explanation. Theseus's decision to seek out the animal makes the episode an early statement of deliberate heroism rather than simple self-defence. Later tradition even links the sow to the Calydonian Boar, carrying the monster's destructive reputation into another heroic cycle.
