Why do witches have pointed hats?
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.
Ear
The pinnae have an effect on facial appearance. In Western societies, protruding ears (present in about 5% of ethnic Europeans) have been considered unattractive, particularly if asymmetric. The first surgery to reduce the projection of prominent ears was published in the medical literature by Ernst Dieffenbach in 1845, and the first case report in 1881.
Pointy ears are a characteristic of some creatures in folklore such as the French croquemitaine, Brazilian curupira or Japanese earth spider. It has been a feature of characters on art as old as that of Ancient Greece and medieval Europe. Pointy ears are a common characteristic of many creatures in the fantasy genre, including elves, faeries, pixies, hobbits, or orcs. They are a characteristic of creatures in the horror genre, such as vampires. Pointy ears are also found in the science fiction genre; for example among the Vulcan and Romulan races of the "Star Trek" universe and the Nightcrawler character from the X-Men universe.
