"Daemonologie. by King of England James I" is a philosophical dissertation published in 1597. Written in response to skeptical works questioning witchcraft's existence, this dialogue between two characters explores necromancy, demonology, and the methods demons use to trouble humanity. King James, influenced by his involvement in the North Berwick witch trials, presents biblical and historical evidence to prove witchcraft's reality while endorsing witch hunting. The work served as a major source for Shakespeare's "Macbeth." (This is an automatically generated summary.)
