In Greek mythology Medusa, (“guardian, protectress”) was a monster, a Gorgon, generally described as having the face of a hideous human female with living venomous snakes in place of hair. Gazing directly upon her would turn onlookers to stone. Most sources describe her as the daughter of Phorcys and Ceto, though the author Hyginus interposes a generation and gives Medusa another chthonic pair as parents.Medusa was beheaded by the hero Perseus, who thereafter used her head as a weapon until he gave it to the goddess Athena to place on her shield. In classical antiquity the image of the head of Medusa appeared in the evil-averting device known as the Gorgoneion. Medusa was originally a ravishingly beautiful maiden, “the jealous aspiration of many suitors,” but when she was caught being raped by the “Lord of the Sea” Poseidon in Athena’s temple, the enraged Athena transformed Medusa’s beautiful hair to serpents and made her face so terrible to behold that the mere sight of it would turn onlookers to stone. In Ovid’s telling, Perseus describes Medusa’s punishment by Minerva (Athena) as just and well earned.
