The Malleus Maleficarum, first published in 1486-7, is the standard medieval text on witchcraft and it remained in print throughout the early modern period. Its descriptions of the evil acts of witches and the ways to exterminate them continue to contribute to our knowledge of early modern law, religion and society. Mackay's highly acclaimed translation, based on his extensive research and detailed analysis of the Latin text, is the only complete English version available, and the most reliable. Now available in a single volume, this key text is at last accessible to students and scholars of medieval history and literature. With detailed explanatory notes and a guide to further reading, this volume offers a unique insight into the fifteenth-century mind and its sense of sin, punishment and retribution.
