A sea-nymph, beloved by Polypheme, but herself in love with Acis. Acis was crushed under a huge rock by the jealous giant, and Galatea threw herself into the sea, where she joined her sister nymphs. Carlo Maratti (16251713) depicted Galatea in the sea and Polypheme sitting on a rock. Handel has an opera entitled Acis and Galatea.
