Ceres was the Roman name of the great Greek goddess Demeter, the protrectress of agriculture and the fruits of the earth. Her worship was borrowed by the Romans from the Greek colonies in Sicily. Her first temple in Rome was established by the dictator A. Postumius Albinus (496 B.C.) to avert a great famine that threatened the city.
A Great festival with games, the Cerealia, was held in honour of the goddess Ceres, and her worship acquired great importance in the city. The decrees of the Senate were deposited in her temple for the inspection of the Tribunes and the People. The word cereal is derived from the name of this god.
