The breaking wheel, also known as the Catherine wheel, was a torture device used in medieval Europe. It consisted of a large wooden wheel with spokes, where the victim's limbs were systematically broken and then woven into the wheel. This method was designed to inflict extreme pain and serve as a public spectacle. The breaking wheel was often used for severe crimes, such as murder or treason, and was intended to deter others from committing similar offenses. Victims could be left on display for hours or even days, highlighting the brutal nature of medieval justice and the harsh penalties imposed by authorities.
