Latin term derived from two words, cornu meaning horn and copia meaning plenty. The horn of plenty is usually shown overflowing with nuts and fruit. Figuratively, it symbolizes prosperity. It assumes mythological importance because of a goat named Amalthea which nursed Zeus. The infant Zeus plucked a horn from the goat's head and endowed it with the ability to overflow with whatever its owner wished for.
