Malleus Maleficarum
The Malleus Maleficarum, usually translated as the Hammer of Witches, is the best known treatise about witchcraft. It was written by the German Catholic clergyman Heinrich Kramer and first published in the German city of Speyer in 1486. Some describe it as the compendium of literature in demonology of the 15th century. Kramer presented his own views as the Roman Catholic Church's position.
