Part of the Cornucopia’s interesting history...
The cornucopia became the attribute of several Greek and Roman deities, particularly those associated with the harvest, prosperity, or spiritual abundance, such as personifications of Earth (Gaia or Terra); the nymph Maia; and Fortuna, the goddess of luck, who had the power to grant prosperity. In Roman Imperial cult, abstract Roman deities who fostered peace (pax Romana) and prosperity were also depicted with a cornucopia, including Abundantia, "Abundance" personified, and Annona, goddess of the grain supply to the city of Rome. Pluto, the classical ruler of the underworld in the mystery religions, was a giver of agricultural, mineral and spiritual wealth and in art often holds a cornucopia to distinguish him from the gloomier Hades, who holds a drinking horn instead.
