Oceanus

In Greek mythology, Oceanus (Greek: Ωκεανος, Okeanos, "river ocean"), also known as Ogenus (Greek: Ωγηνος, Ogenos) or Ogen (Greek: Ωγην), was one of the Titans and the Titan of the sea. He presided over the River Ocean, the largest river that encircled the world. The Ancient Greeks viewed the world differently than how the world actually is and envisioned their land circled by the River Ocean. Certain scholars theorize that Oceanus presided over all salt water, while his wife presided over all fresh water.

As a Titan, Oceanus was a son of Uranus and Gaea, notably the eldest of the Titans. He married his sister, Tethys, and from their union they produced the Oceanides, the Potamoi, and the Aurae. With his sister Theia, Oceanus fathered the Kerkopes, and with his mother, he fathered Creusa.

When the Olympians waged war against the Titans, Oceanus, along with Themis and Prometheus, did not side with the Titans. Oceanus did not fight on either side. Oceanus also refused to rebel with Cronus against their father.
