Rack (torture device)

The rack is a torture device consisting of a rectangular, usually wooden frame, slightly raised from the ground, with a roller at one or both ends. The victim's ankles are fastened to one roller and the wrists are chained to the other. As the interrogation progresses, a handle and ratchet mechanism attached to the top roller are used to very gradually increase the tension on the chains, inducing excruciating pain. By means of pulleys and levers this roller could be rotated on its own axis, thus straining the ropes until the sufferer's joints were dislocated and eventually separated. Additionally, if muscle fibres are stretched excessively, they lose their ability to contract, rendering them ineffective.

One gruesome aspect of being stretched too far on the rack is the loud popping noises made by snapping cartilage, ligaments or bones. One powerful method for putting pressure upon prisoners was to force them to watch someone else being subjected to the rack. Confining the prisoner on the rack enabled further tortures to be simultaneously applied, typically including burning the flanks with hot torches or candles or using pincers made with specially roughened grips to tear out the nails of the fingers and toes. Usually, the victim's shoulders and hips would be separated and their elbows, knees, wrists, and ankles would be dislocated.

The rack was first used in antiquity and it is unclear exactly which civilization it originated from, though some of the earliest examples are from Greece. The Greeks may have first used the rack as a means of torturing slaves and non-citizens, and later in special cases, as in 356 BC, when it was applied to gain a confession from Herostratus, who was later executed for burning down the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World.Arrian's Anabasis of Alexander states that Alexander the Great had the pages who conspired in his assassination, and their mentor, his court historian Callisthenes, tortured on the rack in 328 BC.
