Euryale (English translation: "far-roaming"), in Greek mythology, was one of the Gorgons, three vicious sisters with brass hands, sharp fangs, and hair of living, venomous snakes. She, like her sisters, was able to turn any creature to stone with her gaze. She and her sister Sthenno were immortal, but Medusa, the last of the sisters, was mortal.
They were daughters of Phorcys and Ceto. In many stories, Euryale is noted for her bellowing cries, particularly in the tale of Medusa's death atPerseus' hands.
