The Crommyonian Sow – Plague of the Isthmus of Corinth

The Crommyonian Sow was a pestering wild pig, ruining the areas of the Isthmus of Corinth. It took its name from the village of Crommyon, which suffered the most from the beast’s continuous attacks. On his way to Athens, the hero Theseus came across the Crommyonian Sow and put an end to its rampage.

Origins of the Crommyonian Sow

The Crommyonian Sow was the daughter of Typhon, a monstrous serpentine giant and Echidna, The Mother of Monstrous. She was the sister of the Caucasian Eagle, Cerberus, Chimera, the Colchian Dragon, Lernaean Hydra and Orthrus. While some of her siblings guarded things, the Crommyonian Sow had been left unchecked in the wild to harass and bring ruin on the land as a plague sent by the gods.


The beast of the Crommyon village doesn’t differ much from the Erymanthian Boar. She too was a galling and pestilent monster, scourging the region around the Isthmus of Corinth, and keeping the residents under a veil of terror until Theseus’ blessed arrival.

The myth of the Crommyonian Sow

The setting

The village of Crommyon, from which the irksome sow took its name, was located near the Isthmus of Corinth. The particular establishment stood on the road that united the Attica region with the Peloponnese. Since the area was frequently used by travellers to and from Athens it immediately makes sense how important this crossing was.

The beast

The Crommyonian Sow was a big, human-killing, wild pig (or wild boar as stated in other sources) that couldn’t be stopped. Its dark brown hide and its unnatural size made it look like a terrible monster. According to a version of the myth, the boar’s name was Phaia (meaning ‘grey’), named after a wicked woman who originally owned the beast. Yet, another tale mentions that the monster that oppressed the Crommyon region was in fact a violent woman bandit called ‘The Sow’ because of her foul-mouthed nature and her overweight offspring.

The hero

The great Theseus, The Founding Hero Of Athens, who was destined to slay the mighty Minotaur, a half-man, half-bull monster and become the king of Athens, was traversing the crossing of Corinth when he encountered the Crommyonian Sow. Having vanquished murderous rogues and bandits along the way, Theseus couldn’t let this deadly menace roam free. Either with his sword or with his bare hands the young hero was able to kill the beast and at long last rid the land of its troublesome presence.


Facing Theseus or standing by the side of Phaia, the Crommyonian Sow is represented as an immense tuskless boar.

The Crommyonian Sow had no other role but to wreak havoc on the farm fields and cast its threatening shadow over the Crommyon village.
