The Malleus Maleficarum by Kramer and Sprenger, 1489, Excerpts
In the town of Waldshut on the Rhine, in the diocese of Constance, there was a certain witch who was so detested by the townsfolk that she was not invited to the celebration of a wedding which, however, nearly all the other townsfolk were present. Being indignant because of this, and wishing to be revenged, she summoned a devil and, telling him the cause of her vexation, asked him to raise a hailstorm and drive all the wedding guests from their dancing; and the devil agreed, and raising her up, carried her through the air to a hill near the town, in the sight of some shepherds. And since, as she afterwards confessed, she had no water to pour into the trench (for this, as we shall show, is the method they use to raise hailstorms), she made a small trench and filled it with her urine instead of water, and stirred it with her finger, after their custom, with the devil standing by. Then the devil suddenly raised that liquid up and sent a violent storm of hailstones which fell only on the dancers and townsfolk. And when they had dispersed and were discussing among themselves the cause of that storm, the witch shortly afterwards entered the town; and this greatly aroused their suspicions. But when the shepherds had told what they had seen, their suspicions became almost a certainty. So she was arrested, and confessed that she had done this thing because she had not been invited to the wedding: and for this, and for many other witchcrafts which she had perpetrated, she was burned.
