Oceanus

Oceanus was believed to be the world-ocean in classical antiquity, which the ancient Romans and Greeks considered to be an enormous river encircling the world. In Greek mythology, this world-ocean was personified as a Titan, 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 torso of a serpent. Oceanus, and a fish in one hand and a serpent in the other, gifts of bounty and prophecy.

Oceanus' consort is his wife Tethys, and from their union came the ocean nymphs, also known as the three-thousand Oceanids, and all the rivers of the world, fountains, and lakes. From Kronos, of the race of Titans, the Olympians gods have their birth, and Hera mentions twice in Iliad book xiv her intended journey "to the ends of the generous earth on a visit to Okeanos, whence the gods have risen, and Tethys our mother who brought me up kindly in their own house."

In most variations of the war between the Titans and the Olympians, or Titanomachy, Oceanus, along with Prometheus and Themis, did not take the side of his fellow Titans against the Olympians, but instead withdrew from the conflict. In most variations of this myth, Oceanus also refused to side with Kronus in the latter's revolt against their father, Uranus.
