Also called the Cornu, Cornicello, Wiggly Horn, Unicorn horn, Lucifer’s horn, or Leprechaun staff. The ancient magical charm or amulet worn in Italy as protection against “evil eye” has also been linked to Celtic and Druid myths and beliefs. Other traditions link it to sexual power and good luck. It is often worn with a cross for double protection or luck. In pre-Christian Europe, animal horns pointed to the moon goddess and were considered sacred.
