The Cornucopia was a horn overflowing with produce. The cornucopia was associated with many deities related to harvest, prosperity and agriculture, such as Gaia, Demeter, Abundantia, Fortuna and Plutus. It is used as a symbol of abundance and material prosperity.
In Greek mythology, the cornucopia was created when Alpheus fought Heracles. Alpheus transformed into a bull, but one of his horns was broken off by Heracles. Another myth relates that while Zeus was being raised in a cave on Mount Ida, Crete, he was suckled by Amalthea; a goat. Zeus accidentally broke off one of Amalthea's horns, which he then blessed to forever overflow with produce.
