Book excerpt: In 1665 an anonymous treatise was added to a book skeptical of witchcraft. That book, "The Discoverie of Witchcraft", compiled by Reginald Scot and published in 1584, defended those accused of witchcraft. It also included so many examples of rituals and charms that it became popular with magical practitioners themselves. Although the"Discoverie" has since been reprinted several times, the anonymous material has not been available for over a hundred years. This material features a combination of ceremonial magic, Paracelsian thought, pagan folk rituals, and spirits from John Dee's "A True & Faithful Relation", all mixed into a synthetic whole. "The Magitians Discovered" Volume I is an analysis of who the authors of the anonymous material were, what their worldview was, and what their motivations may have been in assembling and inserting the anonymous material.
