Amphitrite

In ancient Greek mythology, Amphitrite (Ἀμφιτρίτη) was a sea-goddess and wife of Poseidon. Under the influence of the Olympian pantheon, she became merely the consort of Poseidon, and was further diminished by poets to a symbolic representation of the sea. In Roman mythology, the consort of Neptune, a comparatively minor figure, was Salacia, the goddess of saltwater.
