This is the best known (i.e., the most infamous) of the witch-hunt manuals. Written in Latin, the Malleus was first submitted to the University of Cologne on May 9th, 1487. The title is translated as "The Hammer of Witches." Written by James Sprenger and Henry Kramer (of which little is known), the Malleus remained in use for three hundred years. It had tremendous influence in the witch trials in England and on the continent. This translation is in English and was translated by vampire expert Montague Summers The Malleus was used as a judicial case-book for the detection and persecution of witches, specifying rules of evidence and the canonical procedures by which suspected witches were tortured and put to death. Thousands of people (primarily women) were judically murdered as a result of the procedures described in this book, for no reason than a strange birthmark, living alone, mental illness, cultivation of medicinal herbs, or simply because they were falsely accused (often for financial gain by the accuser). The Malleus serves as a horrible warning about what happens when intolerence takes over a society.
