Gorgon
In Greek mythology, the Gorgons were female monsters that had fangs and serpents for hair with bronze claws. They were the daughters of Phorkys and Keto. The serpents in their hair were special: Everyone who looked at them was turned to stone. There were three Gorgons, named Stheno, Euryale and Medusa. Only Medusa was mortal. She was beheaded by Perseus. Medusa's head was brought to Athena. There are many motives showing Athena with an aegis, and a Gorgon's head on her chest.
