A philosophical work on contemporary necromancy and the historical relationships between the various methods of divination used from ancient black magic. This included a study on demonology and the methods demons used to bother troubled men. It also touches on topics such as werewolves and vampires. It was a political yet theological statement to educate a misinformed populace on the history, practices and implications of sorcery and the reasons for persecuting a person in a Christian society accused of being a witch under the rule of canonical law.
