Titans
In Greek mythology, Okeanos embodies the titan who was the son of Uranus and Gaia (according to the Olympian myth), or was the son of Eurynome and Ophion (according to the Pelasgian myth). He was the god of an immense deep current that circled the entire earth.
This "immense deep stream" represented the outer sea to which only gods and heroes had access. While Pontos was the god of the inner sea, accessible to humans.
His siblings were the Titans Koios, Krios, Hyperion, Íapetos, Kronos and the Titans Theia, Rheia, Mnémosyné, Phoibé, Themis and Téthys.
With his wife, and also sister, Thethys had three thousand daughters of the Oceanic women and an equal number of sons. Their children were, for example, Styx, Clymene, Kirké, Métis, Eurynomé, and Thetis.
In the war of the Titans against the Olympian gods, he took no side (as did Themis and Prometheus).
