In Greek mythology, the Graeae were three sisters who had gray hair from their birth and shared one eye and one tooth among them. They were also called the Grey Sisters and the Phorcides

In Greek mythology, Phorcys or Phorcus is a primordial sea god, generally cited as the son of Pontus and Gaia (Earth). Classical scholar Karl Kerenyi conflated Phorcys with the similar sea gods Nereus and Proteus. His wife was Ceto, and he is most notable in myth for fathering by Ceto a host of monstrous children. In extant Hellenistic-Roman mosaics, Phorcys was depicted as a fish-tailed merman with crab-claw legs and red, spiky skin.
