"Medusa" (Adobe Illustrator) #1 in the "Mythology Series"

In a late version of the Medusa tale (related by the Roman poet Ovid) Medusa was originally a beautiful woman. She had sex with Poseidon in Athena's temple. Upon discovery of the desecration of her temple, Athena changed Medusa's form as punishment. Medusa's hair turned into snakes and her glance would turn all living creatures to stone.
