In Greek mythology, Phorcys (Greek: , Phorkus) is a god of the hidden dangers of the deep. He is a primordial sea god, generally cited (first in Hesiod) as the son of Pontus and Gaia. According to the Orphic hymns, Phorcys, Cronus and Rhea were the eldest offspring of Oceanus and Tethys. 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 fore-legs and red-spiked skin.
