This is a Roman amulet and was worn for many centuries as a charm to attract good fortune. The Cornucopia represents Amaitheia's Horn, and is a symbol of prosperity, abundance and fruitfulness. Amaltheia daughter of Melissus, King of Crete, nursed the infant Jupiter with goats milk. Jupiter afterwards endowed the goats horn with magical properties, and promising that it would supply in abundance whatever she desired, gave it to his nurse. The idea most probably originated from using the horns of oxen and goats as drinking cups.
