Using this torture was highly estimated in the times of the Inquisition as a good way of interrogating “taciturn” heretics and wizards. This implement was used in Central Europe, particularly in Nuremberg and in Regensburg. Here regular preliminary inquiries were conducted, up to 1846, where it is was used. The “chairs” had various sizes and shapes, totally covered in spikes, with devices for the painful fixation of the victim or even with iron seats which, if necessary, could be made red-hot. The naked prisoner was seated in the chair in such a pose that any slight movement caused the spikes to pierce into the body. The torture usually lasted several hours, but sometimes was protracted to several weeks. The executioners sometimes aggravated the victim’s torments by puncturing his extremities, using red-hot tongs and other implements of torture.
