Amphitrite was one of the sea nymphs Nereids, fifty sisters in total and daughters of Nereus and Doris. She was the wife of Poseidon and had two children with him; a son named Triton, a merman; and Rhode. Amphitrite also gave birth to other children, such as seals and dolphins. Initially, she was considered an important deity, as mentioned in the Homeric Hymn, when she was present at the birth of Apollo, alongside Dione, Rhea and Themis. Gradually, she became less important and in the end, the poets used her name as a mere representation of the sea. Her Roman counterpart was Salacia, the goddess of saltwater.
Amphitrite is also called Salacia.
