2011 Reprint of 1928 Edition. The Malleus Maleficarum (Latin for "The Hammer of Witches") is a famous treatise on witches, written in 1486 by Heinrich Kramer, an Inquisitor of the Catholic Church, and was first published in Germany in 1487. Jacob Sprenger is also often attributed as an author. The main purpose of the Malleus was to attempt to systematically refute arguments claiming that witchcraft does not exist, discredit those who expressed skepticism about its reality, to claim that witches were more often women than men, and to educate magistrates on the procedures that could find them out and convict them. This edition of Malleus Maleficarum is here translated into English for the first time. It contains a note upon the bibliography of the Malleus Maleficarum and includes bibliographical references. Translated, with introductions, bibliography and notes by Montague Summers.
