In Roman religion and myth, Ceres (Latin: "Cerēs") is the goddess of agriculture, especially the growing of grains and cereals, fertility and motherly relationships. The Roman counterpart of Demeter, Ceres was the central deity of the Plebeian or Aventine Triad, comprised of her, Liber and Libera. She was the mother of Proserpine, who was married to Pluto, the god of the underworld. At Roman weddings, a boy carried the torch of Ceres to light the way to marital happiness. The dwarf planet Ceres is named for her.
