Gods of the seas

Gods of the seas preside over the seas that are nearest to their place or country of origin. Many ancient civilizations were built near a particular sea so these gods were the deities of that sea rather than being a deity of water. Gods of the sea were also sometimes associated with ships, boats, and sailors.
