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, Uranus, sometimes written Ouranos, is the personification of the sky and one of the Greek primordial deities. According to Hesiod, Uranus was the son and husband of Gaia (Earth), with whom he fathered the first generation of Titans. However, no cult addressed directly to Uranus survived into classical times, and Uranus does not appear among the usual themes of Greek painted pottery. Elemental Earth, Sky, and Styx might be joined, however, in solemn invocation in Homeric epic. Uranus is associated with the Roman god Caelus.
