The River at the Edge of the World
Oceanus was the eldest of the twelve Titans, children of Uranus and Gaia. To the early Greeks he was not the sea as we picture it but a vast freshwater river that flowed in an endless circle around the rim of the flat earth, the source of every spring, stream, and ocean current. From his waters the sun, moon, and stars were thought to rise and set.
His name, Okeanos, is of uncertain and possibly pre-Greek origin; it gave us the very word "ocean." With his sister-wife the Titaness Tethys he fathered the three thousand river-gods and the Oceanid nymphs who personified the world's waters.
Unlike his brother Cronus, Oceanus took no part in the rebellion against Uranus or the later war against the Olympians. Remaining neutral in the Titanomachy, he was spared imprisonment in Tartarus and continued, in Greek imagination, to circle the world forever.
Homer calls Oceanus "the begetter of gods" (Iliad 14.201), reflecting an old tradition in which the world-river was the ultimate source of all divine and earthly life, older even than the other Titans. Among his three thousand daughters, the Oceanid nymphs, were some of Greek myth's most consequential figures: Metis, first wife of Zeus and mother of Athena; Doris, mother of the fifty Nereids; Clymene, wife of Iapetus and mother of Prometheus; and Styx, whose underworld river became the gods' most binding oath.
Because Oceanus represented the boundary of the known world, ancient poetry and maps alike placed distant or fantastical peoples along his banks — from the Ethiopians in the far south to the Hyperboreans in the far north — making him as much a mythic horizon as a literal deity.

Common Questions
Is Oceanus the same as Poseidon?
No. Oceanus is an older Titan personifying the world-encircling river, while Poseidon is the Olympian god who later ruled the sea. Oceanus belongs to the primordial generation that preceded Poseidon's rise.
Why was Oceanus not imprisoned in Tartarus?
Oceanus stayed neutral during the Titanomachy rather than siding with Cronus. Because he did not fight the Olympians, he was spared the imprisonment that befell most of the male Titans.
Who were the Oceanids?
The Oceanids were the three thousand daughters of Oceanus and Tethys, nymphs who personified springs, streams, clouds, and other freshwater sources across the Greek world. Several, including Metis, Doris, and Styx, played major roles of their own in later mythology.
