Medusa
The Gorgon
Medusa was the daughter of Phorkys and Keto, the children of Gaia (Earth) and Okeanos (Ocean). She was one of the three sisters known as the "Gorgons". The other two sisters were Sthenno and Euryale. Medusa was the only mortal out of the three. She was once very beautiful and lived far in the north were the sun didn't shine. Being very curious, she wanted to see the sun, and asked the Goddess Athena for permission to visit the south. Athena refused to allow her to visit. Medusa got angry and dared to say that Athena hadn't given her permission because she was jealous of her beauty. Athena was angered and punished her by turning her hair into snakes and cursing her by making her so ugly that who ever lookes at her eyes would turn into stone.
