Poseidon

According to Greek mythology, Poseidon was the god of the sea and the earthquakes, in the same pantheon with Eros and Hephaestus, (TV: Planet of Fire) as well as the son of the titan Kronos and the god of Atlantis, where a temple was dedicated to it. (TV: The Time Monster)

Romans adopted it in their pantheon under the name of Neptune. (PROSE: Byzantium!)
