The "Witch-hammer" allows an accused to have an advocate, but adds: "If the counsellor defends his suspected client too warmly, it is right and reasonable that he should be considered as far more criminal than the sorcerer or the witch herself; that is to say, as the protector of witches and heretics, he is more dangerous than the sorcerer. He should be looked upon with suspicion in the same degree as he makes a zealous defence." But a trial may be difficult enough without being clogged and hampered by a cunning advocate. In order to confuse such a one and ensnare the accused, it is necessary, says the "Witch-hammer," that a judge should remember the words of the apostle, "_Being crafty I caught you with guile_," and show himself crafty. The "Witch-hammer" informs the judge of five "honest and apostolical tricks" (these are the very words of the book); one of them consists in embodying in the copy of the proceedings which is given to the defending lawyer, a number of facts that have not occurred in the trial, and in mixing the names of the witnesses. "By that means the accused and their lawyer may be so confused that they nowise know who has said any thing, or what has been said."
Among the questions to be put to a person under accusation, the "Witch-hammer" recommends a number, the quality of which may be appreciated by reading the following examples: "Do you know that people hold you to be a witch? Why have you been observed upon the precincts of N. N.? Why have you touched N. N.'s child (or cow)? How did it happen that the child (or the cow) soon after fell sick? What was your business outside of your house when the storm broke forth? How can you explain that your cow yields three times as much milk as the cows of others?"
Sprenger's work gives a detailed account of the treatment to which a person who is accused of sorcery and handed over to the judge must be subjected. Before the trial the accused must be put on the rack in order that his mind may be inclined to confession. Some, rather than confess their guilt, allow themselves to be torn asunder limb by limb; they are "the worst witches," and their endurance is explained by the supposition "that the devil hardens them against their tortures." Others who have been less faithful to him he abandons, and are thus easily induced to confess. "If no confession has been wrung from the witch during the first day"--we quote the "Witch-hammer" literally--"the torture is to be continued the second and the third day. The civil law forbids, to be sure, to _repeat_ the torture, when no proof has been adduced, but it may be _continued_."
