The "Zürcher Blutgerichtsordnung" (Procedures for the Blood Court in Zurich) dates from the 15th century and contains a detailed description of how the breaking on the wheel shall occur: Firstly, the delinquent is placed belly down, bound hands and feet outstretched to a board, and thus dragged by a horse to the place of execution. The wheel is then slammed two times on each arm, one blow above the elbow, the other below. Then, each leg gets the same treatment, above and below the knees. The final ninth blow is given at the middle of the spine, so that it breaks. Then, the broken body is woven onto the wheel (i.e. between the spokes), and the wheel is then hammered onto a pole, which is then fastened upright in its other end in the ground. The criminal is then to be left dying "afloat" on the wheel, and be left to rot.
