The Book of Halloween: Now Available!
This fine collection of folklore, "The Book of Halloween" by Kelley, is primarily a work of European extraction but details the pagan origins of its obvious subject matter. Written at the dawn of the 20th century, it traces the history of Halloween, Samhain, etc, through to the then-modern era, providing numerous examples from folklore, poems, and historical materials of the lineage of what would eventually become our now-modern day of candy begging and pumpkins. Not surprisingly it mentions Grimm at several points.
Fairies, jack o'lanterns, and other topics are denoted in some degree of detail along with the usual departed spirits and witchery of that special time of year.
