Amphitrite

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.

[Greek] The queen of the sea, variously given as the daughter of Oceanus and Tethys or of Nereus and Doris. When the sea god Poseidon wanted her as his bride, she declined the honor and hid from him in the Atlantic Ocean. A dolphin not only located her, but also brought her back to him, and he married her. The dolphin was awarded a place in heaven. Their son is the fish-man Triton. Amphitrite was portrayed on Greek amphoras together with her consort, riding in a chariot pulled by sea creatures, or sitting on a sea creature, surrounded by Tritons. She is decorated with the attributes of a queen, her waving hair covered with a net, and sometimes with the pincers of a lobster attached to her temples. The Romans referred to her as Salacia.
