Medusa

In Greek mythology Medusa 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 into her eyes 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.
