Some of the torture inflicted on those suspected of witchcraft was truly horrible.
For instance, water torture was not like the modern water-boarding. Back then, water was funneled down the throat until the victim's stomach was distended to the extreme. One can only imagine how painful that would be.
The strappado was a hanging by the arms, with the arms extended behind the back, designed to disclocate the shoulders. The torture rack, probably the best-known form of torture, was also designed to stretch the victim to the point of disclocation.
Others were placed on The Wheel, lying prone while tied to a large spinning wheel while their limbs were beaten with clubs, again resulting in dislocation and disfigurement.
The list goes on and on. All in the name of religion.
