Mano cornuta and corna
A hand sign with index and little finger raised, used in Italy to ward off the evil eye and elsewhere as an insult.
Also: horned hand, corna, devil horns, fare le corna
The mano cornuta, horned hand, extends the index and little fingers while the others are folded. In Italy it is made pointing downward to ward off the evil eye or bad luck, and a charm in the shape of a horn, the cornicello, serves the same purpose. In Italy and Spain the same sign pointed at a person can mean he is a cuckold, so gestures are read by context. The sign appears in ancient Mediterranean art. Buddhist art shows a similar hand in a mudra that is held to drive away evil. Rock musicians made the sign a symbol of their music from the 1970s, and singer Ronnie James Dio is often credited with spreading it. In Texas it is the Longhorns sign.
