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.

How did the conical hat go from being associated with high status, religious or learned women to being a symbol of scorn or evil? By the late Middle Ages, centuries of war and feudalism began to take their toll on societies. With economic and political unrest, social unrest followed. Fearful of what a disaffected peasantry could do to challenge their power, the Catholic Church along with the Noble families of Europe found convenient scapegoats for the ills of society in their pursuit of witches. It also proved quite profitable. It was during the Inquisition that the conical hat first became associated with something shameful. Those who were accused of heresy, teachings that went against church doctrine, were made to wear the capirote to humiliate them. It is thought very likely by many scholars that the Church deliberately chose this symbol in order to undermine the authority of those in European society who were respected for their knowledge when that knowledge came from any source other than the Catholic Church. Women, particularly, made easy targets. High born women were then attacked for their vanity and sinfulness. Those who made dresses too ornate were punished, and the conical hats quickly disappeared from fashion as being sinful indulgences. Having already successfully reduced an ancient symbol of wisdom to one of vanity and then to shame, it was not such a far step for the Church to further turn it into a symbol of evil and magic.
