One of the most in-depth and scholarly attempts to explain the phenomenon of the Celtic belief in fairies. The mysticism and fairy folklore of Celtic England, Scotland, the Isle of Man, Brittany, and Wales is explored through interviews conducted with everyday citizens about their beliefs, sightings, and encounters in the early 20th century, followed by an anthropological examination of evidence. It is an exploration of the spirit world, of the Sidhe, the “good people,” who are claimed to interact mischievously with the populace - sometimes even abducting them and leaving only the victims' clothes behind, transporting them far distances, and killing their livestock. Narrated with an engaging sense of wonder, this volume offers a valuable resource for students of anthropology and Celtic lore, as well as hours of delightful reading for fairy enthusiasts.
