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).
