One of three monsters in Greek mythology , the most famous of which was Medusa .
According to Hesiod , the three Gorgons were daughters of the sea god Phorcys. Another tradition held that they were created by the earth goddess, Gaea , to aid her sons, the Titans , in their struggle with the gods. Classical art depicts them as winged females with snakes for hair.
