Witch hat
A witch hat (), in popular culture, is the style of hat characterized by a conical crown and a wide brim (like akubras and gats).
The origins of the witch hat as displayed today is disputed. A common theory is that it is an exaggeration of the edgeless hats associated with the Welsh and later the Puritans, or an exaggeration of the conical hats believed to stimulate the brain of the wearer. These "thinking caps" are the precursors to the modern dunce cap. Church despised pointy hats given that the points were often related to those of the devil's horns. The witch hat is a more brimmed version of the cone-shaped hats commonly worn by male-gendered wizards and magicians, as the hat was more brimmed for it to be female-appropriate. As of the Victorian era, fairy tales began depicting black-colored conical hats and crones as symbols of wickedness in their illustrations. Another possibility is that in Luna, a town of the Etruscan civilization, there were coins on one side depicting a goddess commonly associated with witches, named Diana, wearing a brimless, cone-shaped hat.
Mythology of Italy
The Evil Eye is not just an Italian folklore but is present in many different cultures. Each of these cultures have their own versions of the Evil Eye. However, the Evil Eye is very prominent in Italian culture and still a common superstition today among Italians and Italian-Americans. 
The Evil Eye is a look one gives another to put bad luck upon them either causing them misfortune or causing a type of mild physical pain.This look is cast by someone typically because of jealousy and envy.
However Italian culture has two ways to counteract the Evil Eye. These are the Italian Horn, or the “Cornuto” and the “Mano Carnuto”, the hand horn. The Italian Horn is a pendant often worn on a necklace in a shape similar to a chili pepper. This pendant is often in gold or coral and is said to be sacred to the Moon Goddess. This is meant to ward off evil spirits as well. The “Mano Carnuto” is the formation of a hand in a fist with the pinky finger and index finger extended. This is also supposed to ward of negative vibes and the Evil Eye. Both of these counteractions are of Italian origins.
