Salacia

In ancient Greek mythology, Amphitrite (not to be confused with Aphrodite) was a sea-goddess. 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.
