Neptune is the Roman god of the sea and the Roman equivalent of the Greek god Poseidon. He was originally a god of fresh water and became associated with Poseidon early on in Roman history. He lives in a golden palace at the bottom of the sea, where he holds court over sea gods and goddesses, sea nymphs and sea creatures.
