The Headless Horseman And Other Monsters From The Celtic Underworld

has always feared an array of evil forces, monsters, demons, and

with most cultures, they had their demons as well.
Some of the Celtic “monsters” were originally gods but were later demonized as pagan creatures when many of the Celts became Christians.
