Ceres
Ceres found out the spelt wheat (Latin far), the yoking of oxen and ploughing, the sowing, protection and the young seed, the gift of agriculture to human beings. Before this, man were going here and there without houses or rules. She had the power to fertilize, multiply and make plants bear fruit and animals produce seed. Her rules protected all the activities of the agricultural cycle. In January, Ceres (alongside the earth-goddess Tellus) was offered spelt wheat and a pregnant sow. It was done at the movable Feriae Sementivae. This was almost done before the annual sowing of grain. The divine part of sacrifice was the entrails (exta) put in a clay pot (olla). In villages, Cato the Elder describes the offer to Ceres of a porca praecidanea (a pig, offered before harvesting). Before the harvest, she was offered some grains (praemetium). Ovid tells that Ceres "is content with little, provided that her offerings are casta" (pure).
