The way in which the witch murderers reasoned, and their modes of conducting trials and procuring confessions, were truly infernal. The chief rule was that witchcraft being an "exceptional crime," no regard need be had to the ordinary forms of justice. All manner of tortures were freely applied to force confessions. In Scotland "the boot" was used, being an iron case in which the legs are locked up to the knees, and an iron wedge then driven in until sometimes the bones were crushed and the marrow spouted out. Pin sticking, drowning, starving, the rack, were too common to need details. Sometimes the prisoner was hung up by the thumbs, and whipped by one person, while another held lighted candles to the feet and other parts of the body. At Arras, while the prisoners were being torn on the rack, the executioner stood by, sword in hand, promising to cut off at once the heads of those who did not confess. At Offenburg, when the prisoners had been tortured until beyond the power of speaking aloud, they silently assented to abominable confessions read to them out of a book. Many were cheated into confession by the promise of pardon and release, and then burned. A poor woman in Germany was tricked by the hangman, who dressed himself up as a devil and went into her cell. Overpowered by pain, fear and superstition, she begged him to help her out; her beseeching was taken for confession, she was burned, and a ballad which treated the trick as a jolly and comical device, was long popular in the country. Several of the judges in witch cases tell us how victims, utterly weary of their tormented lives, confessed whatever was required, merely as the shortest way to death, and an escape out of their misery. All who dared to argue against the current of popular and judicial delusion were instantly refuted very effectively by being attacked for witchcraft themselves; and once accused, there was little hope of escape. The Jesuit Delrio, in a book published in 1599, states the witch killers' side of the discussion very neatly indeed; for in one and the same chapter he defies any opponents to disprove the existence of witchcraft, and then shows that a denial of witchcraft is the worst of all heresies, and must be punished with death. Quite a number of excellent and sensible people were actually burnt on just this principle. I do not undertake to give details of any witch trials; this sketch of the way in which they operated is all I can make room for, and sufficiently delineates this cruel and bloody humbug.
