Anecdotes
In Greek mythology, Stheno is the eldest of the three Gorgons. Along with her sister Euryale, she is immortal, while the third, Medusa, is the only one of the three who is mortal. It is this distinction that will allow the hero Perseus to kill Medusa, but never her two sisters.
Her name, in Ancient Greek Σθενώ (Sthenố), derives from the word “sthenos” meaning “strength” or “power.” According to certain ancient traditions recorded later, Stheno was said to be the deadliest of the three sisters, having killed more men on her own than her two sisters combined.
Like her sisters, Stheno is described with a head of snakes, boar's tusks, hands of bronze, and sometimes wings of gold. Anyone who met her gaze was turned to stone, a terrifying power shared by all three Gorgons.
The Gorgons, including Stheno, are the daughters of the primordial sea deities Phorcys and Ceto. They belong to a lineage of monstrous creatures that also includes the Graeae, their grey-haired sisters who guard the path leading to the Gorgons.
After Medusa was beheaded by Perseus, her two immortal sisters, Stheno and Euryale, set off in pursuit of the hero to avenge their sister, but could not reach him because he wore the helmet of invisibility of Hades (the kunee).
Primary Sources
Phorcys, mating with Ceto, fathered the fair-cheeked Graeae, [...] and the Gorgons who dwell beyond glorious Ocean, at the edge of night: Stheno, Euryale, and Medusa of the sorrowful fate. She alone was mortal, while the other two were immortal and ageless.
The Gorgons were Stheno, Euryale, and Medusa. Medusa alone was mortal; that is why Perseus was sent to fetch her head. They had heads encircled with the scales of dragons, great tusks like boars', hands of bronze, and golden wings on which they flew.
Perseus's account of the Gorgons, whose gaze turned to stone anyone who beheld them, and of the birth of Pegasus and Chrysaor from the blood of the beheaded Medusa.
An evocation of Perseus slaying the Gorgon and of the mournful song raised by her immortal sisters, a lament that Athena imitated when she invented the flute (the *aulos*) of many voices.
Key Places
According to Hesiod, the Gorgons dwell at the edges of the world, beyond the river Ocean, near the realm of Night. A mythical place marking the boundary of the world known to the Greeks.
Several ancient traditions, notably in Herodotus and the Roman authors, place the lair of the Gorgons at the edges of Libya, at the far west of the Mediterranean world.
A mythical region of the far West associated with the domain of the Gorgons, close to the place where Atlas holds up the sky. Perseus passes through it during his quest.
An island of the Cyclades from which Perseus sets out on his quest for the head of Medusa. It is the starting point of the adventure that seals the fate of the Gorgons.
Site of the oldest surviving monumental Greek pediment, decorated with an enormous Gorgon (around 580 BC). A major testimony to the iconography of the Gorgons.
Typical Objects

Emblematic attribute of the three Gorgons, including Stheno: a head of hair made of living snakes that writhe around their heads. It symbolizes their monstrous and terrifying nature.

According to Apollodorus, the Gorgons have hands of bronze, a token of their superhuman strength. This attribute underscores their power, especially in Stheno, “the mighty one.”

The Gorgons are endowed with golden wings that allow them to fly. These wings enable Stheno and Euryale to pursue Perseus after the death of Medusa.

Great tusks resembling those of boars adorn the mouths of the Gorgons in their archaic depictions. They heighten the bestial and frightening aspect of these creatures.

A mask or head of a Gorgon used as an apotropaic amulet in the Greek world, believed to ward off the evil eye. It appears on shields, temple pediments, and coins.

A power shared by all three Gorgons: their gaze turns to stone anyone who meets it. It is the most formidable weapon of Stheno and her sisters.

Daily Life
Morning
As a mythological figure, Stheno has no human daily routine. The texts describe her living at the edges of the world, beyond the Ocean, in an isolated dwelling she shares with her sisters Euryale and Medusa, far from the eyes of mortals.
Afternoon
The tales attribute to the Gorgons an existence as fierce guardians of their forbidden territory. Later tradition makes Stheno the most warlike of the three, feared for the number of mortals she is said to have petrified or killed.
Evening
Hesiod places their dwelling “at the edges of the night,” a place of eternal gloom near the realm of darkness. The mythical evening of the Gorgons merges with the permanent obscurity of these remote regions.
Food
No ancient source describes the diet of the Gorgons, monstrous creatures beyond human needs. Their demonic nature places them outside the ordinary cycle of mortal nourishment.
Clothing
Archaic iconography does not really clothe the Gorgons in costumes: they are defined by their bodily attributes — a hair of serpents, tusks, golden wings and bronze hands — rather than by garments.
Housing
The Gorgons inhabit a mythical land at the far west of the world, sometimes located beyond the Ocean, sometimes in Libya or near the Hesperides. This inaccessible place symbolizes the boundary between the human world and the monstrous beyond.
