The “Crommyonian Sow” (Greek Κρομμυωνία σῦς, translit. Krommyōnía sŷs) was so named because she lived near the town of Crommyon in the region of Corinthia.

Alternate Names

In some later sources, the Crommyonian Sow bore the name “Phaea” (Greek Φαιά, translit. Phaiá; also spelled Φαῖα/Phaîa[1]), meaning “gray.”[2]



The Crommyonian Sow was a sow—a wild female pig—of exceptional size, strength, and ferocity.[3] The creature lived near Crommyon, a small town in the region of Corinthia on the Saronic Gulf (though it was originally part of the Megarid). This fearsome sow harassed the area, killing many people before finally being slain by Theseus.[4]

The Crommyonian Sow was one of Theseus’ less important conquests, but she did occasionally appear in ancient art, especially in Athenian vase painting from the fifth century BCE. She was represented as a creature of prodigious size and usually shown in battle with Theseus. An old woman was often depicted with the sow, no doubt the owner of the terrible beast.[5]


In the earliest traditions, the Crommyonian Sow was a fairly ordinary animal; but later accounts, perhaps hoping to build up her fearsomeness, seem to have embellished her pedigree. The mythographer Apollodorus, for example, reports a tradition in which the Crommyonian Sow was the child of the monsters Typhoeus and Echidna.[6] Another tradition, reported by the geographer Strabo, made the Crommyonian Sow the mother of the Calydonian Boar.[7]


The Crommyonian Sow is best known as one of the foes Theseus faced on his journey to meet his father Aegeus, the king of Athens. These opponents (sometimes referred to as the “Six Labors of Theseus”) plagued the isthmus road—the narrow strip of land connecting the Peloponnese with the rest of mainland Greece. While traveling from his mother’s home in Troezen to his father’s kingdom in Athens, Theseus cleared the isthmus of the dangerous bandits and creatures that infested it.

The Crommyonian Sow was a monstrously strong and large creature, responsible for killing many people. In some traditions, it had been bred by an old woman named Phaea, who instilled in it a thirst for blood. In the end, Theseus fought and killed the beast.[8]

A rationalized variant of the myth of the Crommyonian Sow is recorded by Plutarch. According to this interpretation, the so-called Crommyonian Sow was not a real sow at all, but rather a female bandit from Crommyon named Phaea who had been nicknamed the “Crommyonian Sow” on account of her unfortunate hygiene.[9]

  2. Apollodorus, Epitome 1.1; Plutarch, Life of Theseus 9; Pausanias, Description of Greece 2.1.3; Stephanus of Byzantium, Ethnica, s.v. “Φαῖα (Phaîa).”

  3. Hyginus, Fabulae 38, breaks tradition by describing the creature as a boar—that is, male—rather than a sow. There is also an Attic red-figure cup from ca. 520–510 BCE (British Museum, London, no. E36) that represents Theseus capturing a boar. This may hint at a variant of the myth, or it may be nothing more than artistic license.

  4. See esp. Bacchylides, Dithyramb 18.23–24; Diodorus of Sicily, Library of History 4.59.4.

  5. The name of the creature’s owner is uncertain. Apollodorus called the woman who raised the Crommyonian Sow “Phaea” (Epitome 1.1), but on one red-figure cup by Aison from ca. 420–410 BCE (Archaeological Museum, Madrid, no. L196), the woman is identified as “Crommyo.” On the Crommyonian Sow in ancient art, see Eva Simantoni-Bournia, “Krommyo,” in Lexicon Iconographicum Mythologiae Classicae (Zurich: Artemis, 1992), 6:139–42.

Primary Sources

The earliest literary reference to the Crommyonian Sow comes from a poem by Bacchylides (ca. 520–ca. 450 BCE). The myth and its context is summarized in later works by Diodorus of Sicily (before 90–after 30 BCE), Apollodorus or “Pseudo-Apollodorus” (first century BCE/first few centuries CE), and Plutarch (born before 50 CE, died after 120 CE). A few of these later sources also add that the creature was named “Phaea.”

Additional snippets of information on the Crommyonian Sow can be found in works by the geographers Strabo (ca. 63 BCE–ca. 23 CE) and Pausanias (ca. 115–ca. 180 CE), as well as in later commentaries from the scholia. For further references, see the notes.
