Oceanus

Oceanus was the divine personification of the ocean, an enormous river encircling the world.

Strictly speaking, Oceanus was the ocean-stream at the Equator in which floated the habitable hemisphere. He is personified as a son of Uranus and Gaia. In Hellenistic and Roman mosaics, this Titan was often depicted as having the upper body of a muscular man with a long beard and horns (often represented as the claws of a crab) and the lower body of a serpent. On a fragmentary archaic vessel of circa 580 BC, among the gods arriving at the wedding of Peleus and Thetis, is a fish-tailed Oceanus, with a fish in one hand and a serpent in the other, gifts of bounty and prophecy. In Roman mosaics he might carry a steering oar and cradle a ship.

Oceanus' consort was his sister, Tethys, and from their union came the ocean nymphs, also known as the Oceanides, and all the rivers, fountains, and lakes of the world.

In most variations of the war between the Titans and Olympians, Oceanus, along with Prometheus and Themis, did not take the side of the Titans, but instead withdrew from the conflict. Oceanus also refused to side with Cronus in their revolt against their father, Uranus.
