This history of witchcraft and demonology is written by Montague Summers, who spent a period of time serving as a Catholic priest. He makes many references to religion and the Bible in this text and demonstrates the danger and evil in all forms of occultism. He refers to various supernatural events and offers explanations for seemingly inexplicable incidents. First published in 1926, this occultist study is recommended for those who wish to deepen their understanding of witchcraft and other supernatural powers.
