A treatise on witchcraft, first published in 1487 by Heinrich Kramer and Jacob Sprenger. Often referred to as 'The Hammer of Witches,' it was a comprehensive guide for identifying, prosecuting, and torturing witches, and was highly influential during the witch trials in Europe for centuries.
Malus Maliporum, you know, the hammer of the evildoers. That was the first book on witches.
""A speaker mentions 'Malus Maliporum' (Malleus Maleficarum) as 'the first book on witches' in the context of early printing press publications."
