In Greek mythology, Euryale was the second eldest one of the Gorgons. She and her sister Stheno, were immortal, where as Medusa was mortal. According to some versions, Euryale was transformed into a Gorgon because of standing with her sister Medusa, who was raped by the sea god Poseidon in the Temple of Athena. In many stories, Euryale is noted for her bellowing cries, particularly in the tale of Medusa's death at Perseus' hands.
