“The use of the Corno, or Devil’s Horn, is a curse of impotency or of the cuckold. The twisted phallic red coral, gold or silver amulet (cornicello) is often worn or carried by men to ward off curses on their “manliness” or mojo. Although many claim the amulet represents one of the horns of the devil, the Corno predates Christianity by thousands of years. The horned god Faunus was known for his wild nature and interest in fertility. The ancient Romans knew well Cernunnos, the horned Celtic god of fertility, life, animals, wealth, and the underworld. The horns of an African eland most resemble the original amulets.
