the Ocean
Oceanous was the titan of the seas. He married Gaea after her first husband, Uranus had died from Gaea's son Cronus.
Gaea is the Goddess of Earth. She is the first god/goddess in Greek mythology. Before her was only empty space called Chaos. She had her first son, Uranus, then married him. Gaea first bore him Armored Giants. Feared of these Giants, Uranus ate them. They went down to the Underworld, where they never died because they are Gods. Then Gaea bore Cyclops. Feared of their power and strength, Uranus ate them. Then Gaea bore 6 Titans. Uranus did not eat them because he felt stronger than them for they did not appear strong. There is a lot left to the story you can read in the book, Mythology And You. There are many different interpretations on exactly how the story went but this one was that book's interpretation. Some think that the Titans were born first and the Zeus was Uranus' son. But most say that Zeus was his grandson. You should really read about it.
