3000 years ago, in Celtic Ireland, October 31st marked the end of the year. Once darkness fell on October 31st, the new year, Samhain, began. The moment between the end of the old year and the beginning of a new year is a loophole, a moment of confusion, a door opening to the spirit world. The spirits of the dead roam freely, crossing into the world of the living. Not all of them were welcomed. Some of these spirits might be pooka, changelings who kidnap the souls of the living, leaving an evil spirit in its stead. Or the witch-like banshees, the omens of doom. How can you protect yourself from these potentially evil spirits??
Trick 'em! Confuse 'em! Warn them to stay away!
But they knew better than to wear a goofy Orphan Annie costume. Their costumes were much, much scarier.
They wore their clothes- INSIDE OUT!!! ahhhhhh!
(Fun fact: that's also how people dressed for the first Mardi Gras in Louisiana- 300 years ago!)
Some Celts with more time on their hands might make their costumes out of animal parts...
Who looks more menacing?
