In Europe, the panic over witchcraft was supported by the "Malleus Maleficarum", published in 1487 by Heinrich Kramer, a German Catholic clergyman. It taught the prosecution of witches and was greatly promoted by the new technology of the printing press. It saw 29 printings before 1669, second only to the Bible. The book says that three elements are necessary for witchcraft. These are the evil intentions of the witch, the help of the Devil, and the permission of God.
