The Gorgons were three monsters in Greek mythology, daughters of Echidna and Typhon, the mother and father of all monsters respectively. Their names were Stheno, Euryale, and the most famous of them, Medusa. Although the first two were immortal, Medusa was not. Weirdly, Medusa was also not considered the child of Echidna and Typhon, but of Phorkys and Keto. Their faces were ugly and their hair was replaced by snakes; anyone who would gaze into their eyes would be turned to stone instantly. and she was killed by the hero Perseus.
