In Greek mythology, Pontus was an ancient, pre-Olympian sea-god, one of the Greek primordial deities. Pontus was Gaia's son and has no father; according to the Greek poet Hesiod, he was born without coupling, though according to Hyginus, Pontus is the son of Aether and Gaia.

In Greek mythology, Gaia, also spelled Gaea, is the personification of Earth. Gaia is the ancestral mother—sometimes parthenogenic—of all life. She is the mother of Uranus (Sky), from whose sexual union she bore the Titans, the Cyclopes, and the Giants; as well as of Pontus (Sea), from whose union she bore the primordial sea gods. Her equivalent in the Roman pantheon was Terra.
