Medusa
In Greek mythology, the most famous of the monsters known as Gorgons. Anyone who looked directly at Medusa turned to stone. She was the only Gorgon who was mortal. The hero Perseus, looking only at her reflection in a shield given to him by Athena, killed her by cutting off her head. Perseus later gave the severed head to Athena, who placed it in her shield; according to another account, he buried it in the marketplace of Argos.
