Letters on Demonology and Witchcraft was written by Sir Walter Scott when educated society believed itself in enlightened times due to advances in modern science. The book, however, revealed that all social classes still held beliefs in ghosts, witches, warlocks, fairies, elves, diabolism, the occult, and even werewolves. Sourcing from prior sixteenth and seventeenth century treatises on demonology along with contemporary accounts from England, Europe, and North America (Cotton Mather's Magnalia Christi, for one), Scott's discourses on the psychological, religious, physical, and preternatural explanations for these beliefs are essential reading for acolytes of the dark and macabre; the letters dealing with witch hunts, trials, and torture are morbidly compelling.
