Oceanus is the titan of the sea. Many ancient Greeks and (later on) Romans, believed that Oceanus was the divine personification  of the sea, an enormous river encircling the world. In Greek mythology, Oceanus is the son of Gaia and Uranus and was personified as a titan. But in Rome’s mythology, Oceanus was described has a titan that had the upper body of a muscular man with a long beard and horns usually, which were crab claws and the lower body was a serpent. People also believe that Oceanus represents all the bodies of salt water including the Mediterranean sea and the Atlantic ocean. In the story about the war between the gods called the titans Titanomachy, Oceanus, Prometheus, and Themis did not participate in the war nor did they side with the titans. They instead withdrew from the war. In addition to his own revolt against the conflict, Oceanus  refused to help Cronus later on in an uprising against  the father of all of the Titans known today as Uranus.
