Ceres

Ceres is the Goddess of agriculture. During a drought in 496 BCE, the Sibylline Books ordered the institution of the worship of Demeter, Dionysus and Persephone, called by the Latin names Ceres, Liber and Libera. Ceres was the Goddess of the plebeians: the Ædiles Plebis cared for her temple and had their official residences in it, and were responsible for the games at the Cerealia, her original festival on April 12-19. There was a women's 9-day fast and festival when women offered the first corn harvest to Ceres, originally celebrated every five years, but later - by the time of Augustus - held every October 4.
