Wheels were adapted to many torturous uses. They could be part of a stretching rack, but medieval torturers were far too creative to leave it at that. Early torturers were fond of tying someone to a large wooden wheel, then pushing it down a rocky hillside. A more elaborate method involved a wheel mounted to an A-frame that allowed it to swing freely. The victim would be tied to the wheel, and then swung across some undesirable thing below -- fire was always a good choice, but dragging the victim's flesh across metal spikes also worked well. The wheel itself could also have spikes mounted on it, so the pain came from all directions. Instead of swinging, the wheel might turn on an axle. The difference was likely immaterial to the victims.
One of the most horrible wheel tortures was akin to crucifixion. The victim would have the bones in all four limbs broken in two places by strikes from an iron bar. Then, the shattered limbs were threaded through the spokes of a large wheel. Finally, the wheel would be attached to the top of a tall wooden pole and left out in the sun for days. The victim might be alive for hours, enduring the agony of his or her mangled arms and legs and the relentless sun, not to mention the attentions of crows [source: Hunt].
Next, we'll learn about two torture methods that were still used even after the Middle Ages had ended.
