Gorgon (gôrˈgən) [key], in Greek mythology, one of three monstrous sisters, Stheno, Euryale, and Medusa; daughters of Ceto and Phorcus. Their hair was a cluster of writhing snakes, and their faces were so hideous that all who saw them were turned to stone. Only Medusa was mortal. They were much represented in Greek art.
