Cornucopia

Also called the Horn of Plenty, the cornucopia is often depicted in paintings and on friezes where it symbolizes the notion of boundless abundance, as flowers, fruits, sheaves of wheat, and other produce spill out of a hollow horn or a twisting basket woven in the shape of the horn.

The origin of the cornucopia is found in the Greek myth of Amalthea. Amalthea fed the infant Zeus a drink of goat’s milk and was given the brimming goat’s horn as a reward. Sometimes the infant Zeus is depicted being fed the milk from the horn itself.

The cornucopia, as a symbol of a bounteous harvest, is also associated with Ceres, the Goddess of corn, and also with Fortuna, Goddess of good fortune. The idea of a bottomless, bounteous container has similarities to the symbol of the cauldron.
