The most common instrument of torture was the "strappado", which was a simple rope and pulley system. With the pulley attached to ceiling of the chamber, the lifting rope was tied to the wrist of the victim, whose hands were tied behind their back. Subsequently, the victim was raised to the ceiling and then lowered using a jerking motion causing dislocation of the shoulder joints. To increase the suffering caused by the strappado, weights were attached to the feet of the victim.
