If you’d been around for the earliest Halloween celebrations, you might have worn animal skins and heads.

According to ancient Roman records, tribes located in today’s Germany and France traditionally wore costumes of animal heads and skins to connect to spirits of the dead. This tradition continued into modern day celebrations of Samhain, the Celtic holiday that inspired Halloween in America. On this day, merry-makers often dressed as evil spirits simply by blackening their faces. The leader of the Samhain parades wore a white sheet and carried a wooden horse head or a decorated horse skull (a modern Welsh version of this costume is shown above). Young people also celebrated by cross-dressing.
