Acis and Galatea are characters from Greek mythology later associated together in Ovid's Metamorphoses. The episode tells of the love between the mortal Acis and the Nereid (sea-nymph) Galatea; when the jealous Cyclops Polyphemus kills Acis, Galatea transforms her lover into an immortal river spirit. The episode was made the subject of poems, operas, paintings, and statues in the Renaissance and after.

In Greek mythology, the Nereids or Nereides are sea nymphs, the 50 daughters of the 'Old Man of the Sea' Nereus and the Oceanid Doris, sisters to their brother Nerites. They often accompany Poseidon, the god of the sea, and can be friendly and helpful to sailors.
