Euryale was the second eldest of the Gorgons, three vicious sisters with brass hands, sharp fangs, and hair of living, venomous snakes. She and her sister Stheno, were immortal, where as Medusa was mortal. In some versions of mythology, Euryale also had the ability to turn anyone to stone with her gaze.
They were daughters of primordial sea god and goddess Phorcys and Ceto, who personified the dangers of the sea. In many stories, Euryale is noted for her bellowing cries, particularly in the tale of Medusa's death at Perseus' hands.
