In Greek mythology, Medusa (Greek: Μέδουσα (Médousa), "guardian, protectress") was a gorgon, a chthonic female monster; gazing upon her would turn onlookers to stone. She was beheaded by the hero Perseus, who thereafter used her head as a weapon until giving it to the goddess Athena to place on her shield. In classical antiquity and today, the image of the head of Medusa finds expression in the evil-averting device known as the Gorgoneion. She also has two gorgon sisters.
