He was the Greek god for wine and celebration.
Demeter, the Greek Goddess of fertility and the harvest, has a daughter called Persephone. Persephone was accidentally forced to spend half of the year in the Underworld with Hades as his wife, and that is why Autumn and Winter are cold and infertile, as Demeter mourns for her daughter.
