Ceres was the goddess of farming and the harvest. Her daughter, Proserpina was kidnapped by Pluto who wanted to marry her. As a result, Ceres stopped fertilising the soil. Faced with a situation that would quickly become critical for the mortals, a compromise was found: Proserpina would live in Hell with Pluto but be able to come to the surface for 9 months to see her mother, which would make the soil fertile once more. Thus were created the seasons.
