The idea that witches were members of organized heretical sects or part of a vast diabolical conspiracy crystalized most clearly in a handful of texts written in the 1430s and clustered geographically around the arc of the western Alps. Michael D. Bailey presents accessible English translations of the five oldest surviving texts describing the witches sabbath and of two witch trials from the period. These sources, some of which were previously unavailable in English or available only in incomplete or out-of-date translations, show how perceptions of witchcraft shifted from a general belief in harmful magic practiced by individuals to a conspiratorial and organized threat that led to the witch hunts that shook northern Europe and went on to influence conceptions of diabolical witchcraft for centuries to come.
