The Gorgons in Greek mythology: Stheno, Euryale and Medusa

The Gorgons are three monstrous sisters in Greek mythology: Stheno, Euryale and Medusa. Daughters of the sea deities Phorcys and Ceto, they live beyond the river Ocean at the edge of the world, and anyone who looks at them is turned to stone. Two of them are immortal. The third, Medusa, is not, and she is the one Perseus beheads. This page is about the group as a whole: who the sisters are, where they live, how ancient writers and artists pictured them, and how a trio slowly turned into a single famous face. Medusa’s own story, from her transformation to the birth of Pegasus, has its own entry.

The three Gorgons and their names

The earliest full account is in Hesiod’s Theogony (270-283). After the Graeae, Ceto bears Phorcys “the Gorgons who dwell beyond glorious Ocean, at the world’s edge toward Night, where the clear-voiced Hesperides are”. Hesiod names them as Sthenno, Euryale and Medusa, “who suffered a grievous fate”, and then states the rule that drives the whole myth: Medusa was mortal, while her two sisters were “deathless and ageless”.

Stheno and Euryale have almost no stories of their own. They appear only around their sister’s death, first to chase her killer and then to mourn her. The trio works as a unit with a single weak point, and Perseus’ quest is built around that one gap.

Their names say the same thing. Stheno points to strength, Euryale to wide range (perhaps the wide sea, fitting for daughters of sea gods), Medusa to guarding or ruling. None of them describes ugliness. These are names for powers, not for freaks.

Family and home at the edge of the world

The Gorgons belong to the brood of Phorcys and Ceto, the line Hesiod reserves for beings of the margins. Their sisters are the Graeae, born gray-haired. Hesiod names only two, Pemphredo and Enyo; Aeschylus and Apollodorus count three and give them one eye and one tooth to share. The next lines of the Theogony describe the birth of Echidna, but the pronoun that names her mother is ambiguous. Most readers take it to mean Ceto, which would make Echidna another sister of the Gorgons.

Location matters as much as lineage. Hesiod puts the Gorgons in the far west, where the sun sets, next door to the Hesperides. It is the zone where the inhabited world gives way to Night. Aeschylus, in Prometheus Bound, speaks instead of the “Gorgonean plains of Cisthene” somewhere along Io’s fabulous wanderings. The place shifts, but it always lies beyond the known world.

Later writers move the Gorgons to Libya. Apollonius of Rhodes and Ovid both say that drops of blood falling from Medusa’s head as Perseus flew over that land became its desert snakes. Pausanias (2.21.5-6) gives a rationalized version in which Medusa was a queen of the peoples around Lake Tritonis, killed at night by Perseus, with her head buried under a mound in the agora of Argos. Diodorus of Sicily (book 3) goes further and turns the Gorgons into a nation of warrior women, rivals of the Libyan Amazons.

What did the Gorgons look like?

Their appearance is built up by successive authors, each adding a layer.

The Shield of Heracles, a poem attributed to Hesiod but composed later, describes a scene worked on the hero’s shield (216-237). Perseus flees with the head in his bag and the cap of Hades on his head, while behind him the two Gorgons, “unapproachable and unspeakable”, rush to catch him. Two snakes hang from their belts, flicking their tongues and gnashing their teeth, and the shield seems to ring with the noise of the chase.

Aeschylus (Prometheus Bound, 798-800) calls them winged and snake-haired, loathed by mortals: no man can look at them and keep his breath.

Apollodorus (Library, 2.4.2) gives the fullest portrait: heads wreathed in dragon scales, great tusks like a boar’s, hands of bronze, and golden wings to fly with. Anyone who sees them is turned to stone.

The result is a composite creature, part woman, part snake, part boar and part bird. That mix explains much of the archaic image: before the Gorgon became a face, she was a pile of signs of aggression.

The chase and the lament

The immortal sisters only come into view at Medusa’s death. In Perseus and Medusa, they wake to the killing and set off after the hero, who escapes them in the cap that makes him invisible. Apollodorus says Perseus found all three asleep and, with Athena guiding his hand, struck while watching their reflection in a bronze shield; the adamantine sickle came from Hermes.

Archaic vase painters loved the chase. The name vase of the Nessos Painter (Athens, National Archaeological Museum, around 620 BC) shows two Gorgons running at full stride while Medusa’s headless body collapses. Perseus is not even in the picture: the whole scene is the sisters’ pursuit.

Pindar gives their grief an unexpected sequel. His twelfth Pythian, written for a pipe player from Acragas, tells how Athena heard the dirge rising from Euryale’s jaws and from the snakes’ heads, and invented a melody for the aulos to imitate it, the “many-headed tune”. Music is born from the Gorgons’ mourning. The same poem calls Medusa “fair-cheeked”, which shows that a beautiful Gorgon was already imaginable in the early fifth century BC.

One Gorgon or three? Homer and Euripides

Homer has no trio, and he does not connect Perseus to the Gorgon. The Iliad knows a single head: on Athena’s aegis is “the Gorgon’s head, a dread monster” (5.741-742), and Agamemnon’s shield bears a grim-eyed Gorgo flanked by Terror and Rout (11.36-37). In the Odyssey (11.633-635), Odysseus leaves the underworld in a hurry for fear that Persephone will send up the Gorgon’s head against him. For Homer, the Gorgon is an image and a threat rather than a character.

Euripides offers a different origin in Ion (989-997). There the Gorgon is a monster born of Gaia at Phlegra to help the Giants against the gods, and Athena herself kills it and wears its hide as her aegis. This version cuts Perseus out entirely and makes the killing the goddess’s own deed, which fits the title Gorgophone, “Gorgon-slayer”, that Euripides gives her in the same play.

The gorgoneion: from grimace to beauty

The gorgoneion, the Gorgon’s face on its own, is among the most common images in Greek art. It appears on shields, breastplates, roof antefixes, coins and the inside of drinking cups.

The archaic type is frontal and grotesque: bulging eyes, lolling tongue, bared teeth and sometimes tusks, with snakes for hair or belt. The most monumental example is the west pediment of the Temple of Artemis on Corfu (around 580 BC, now in the Corfu Archaeological Museum). A giant Gorgon in running pose fills the center between two great cats, with Pegasus and Chrysaor beside her, even though they were born at her death. The image does not tell a story; it stands guard.

In later art the face softens. The Medusa Rondanini, a Roman marble copy in the Munich Glyptothek after a Greek original whose date is debated (Classical or Hellenistic), shows a calm young woman with snakes knotted under her chin. This “beautiful Medusa” leads to Ovid (Metamorphoses, 4.772-803), where Medusa is a girl turned into a monster after Poseidon rapes her in Minerva’s temple. From then on, the group fades behind a single figure.

The Gorgon’s blood

Gorgon blood cuts both ways. According to Apollodorus (3.10.3), Asclepius received from Athena the blood from the Gorgon’s veins: what flowed from the left side was deadly, what flowed from the right side saved life, and he used it to raise the dead. Euripides’ Ion (999-1017) knows the same split: two drops, one that cures disease and one that kills, passed from Athena to Erichthonius and then to Creusa in a golden bracelet.

How to read the Gorgons

The oldest reading is apotropaic: the Gorgon wards off evil by showing it. That is already how the aegis and Agamemnon’s shield work in Homer. Modern scholars have added other readings. In La Mort dans les yeux (1985), Jean-Pierre Vernant argued that the Gorgon’s face, always shown head-on, embodies radical otherness: to look at the Gorgon is to meet death looking back at you. Psychoanalytic and historical readings have also been proposed. None rests on an ancient text that hands over the key, so they are best treated as hypotheses.

What the ancient sources say

• Homer (Iliad, 5.741-742 and 11.36-37; Odyssey, 11.633-635) knows a single Gorgon, reduced to a frightening head on the aegis or in the underworld.
• Hesiod (Theogony, 270-283) fixes the trio, their parents, their home near the Hesperides and Medusa’s lone mortality.
• The Shield of Heracles (216-237) pictures the two sisters chasing Perseus.
• Pindar (Pythian 12) derives Athena’s aulos tune from Euryale’s lament.
• Aeschylus (Prometheus Bound, 798-800) makes them winged and snake-haired.
• Euripides (Ion, 989-1017) has the Gorgon born of Gaia, killed by Athena, and gives her blood a double power.
• Apollodorus (Library, 2.4.2-3 and 3.10.3) supplies the standard portrait and the link with Asclepius.
• Ovid (Metamorphoses, 4.772-803) centers everything on Medusa as a punished young woman.
• Pausanias (2.21.5-6) and Diodorus (book 3) offer rationalized versions set in Libya.

Further reading

For the one mortal Gorgon, read Medusa, then the full story of Perseus and Medusa. For the hero, see Perseus and, for the next stage of his journey, Andromeda. The Gorgons’ sea-born family is covered in Phorcys, Ceto and Echidna, and their western neighbors in the Hesperides. The goddess who wears the head on her aegis is Athena. For the wider picture, start from Greek mythology.
