Amphitrite 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. Her Roman equivalent was Salacia.
Though Amphitrite does not figure in Greek cultus, at an archaic stage she was of outstanding importance, for in the Homeric Hymn to Delian Apollo, she appears at the birthing of Apollo among "all the chiefest of the goddesses, Dione and Rhea and Ichnaea and Themis and loud-moaning Amphitrite." Theseus in the submarine halls of his father Poseidon saw the daughters of Nereus dancing with liquid feet, and "august, ox-eyed Amphitrite", who wreathed him with her wedding wreath, according to a fragment of Bacchylides. Jane Ellen Harrison recognized in the poetic treatment an authentic echo of Amphitrite's early importance: "It would have been much simpler for Poseidon to recognize his own son... the myth belongs to that early stratum of mythology when Poseidon was not yet god of the sea, or, at least, no-wise supreme there—Amphitrite and the Nereids ruled there, with their servants the Tritons. Even so late as the Iliad Amphitrite is not yet 'Neptuni uxor'" [Neptune's wife]".
