The Cornucopia (Latin, ‘horn of plenty’), a spiraling, woven basket overflowing with an abundance of produce, is an ever-present symbol of harvest prosperity. The symbol dates back to an ancient tale of the Nymph Amalthea,* who, as a reward from the infant Zeus for a meal of Goat’s milk, was given an enchanted goat’s horn which gave whatever one wished for.**
The cornucopia became a ubiquitous symbol of fortune and plenty, and was associated with many Goddesses, including Fortuna, the goddess of good fortune, and Ceres, Goddess of agriculture.
