Oceanus
The great Titan who personified the vast river believed to encircle the entire world. Father of all the rivers, springs, and ocean nymphs.
The Myth of Oceanus
Oceanus was the eldest of the twelve Titans, son of Ouranos and Gaia. He personified the great freshwater river the Greeks believed encircled the flat earth. Unlike the salt sea ruled by Poseidon, Oceanus was the source of all freshwater — every river, spring, and stream flowed from him. With his wife Tethys he fathered three thousand river gods and three thousand Oceanids, nymphs of springs and streams. Among his daughters were Metis, first wife of Zeus, Styx, by whose waters the gods swore oaths, and Clymene, mother of Prometheus and Atlas. Uniquely among the Titans, Oceanus did not fight against Zeus in the Titanomachy and was spared imprisonment in Tartarus. In Aeschylus, he visits Prometheus chained to the rock and urges submission. He continued to flow around the world, a force older than the Olympian order — primordial, patient, and unbroken.
