Dismemberment is the act of cutting, tearing, pulling, wrenching or otherwise removing, the limb of a living thing. It may be practiced upon human beings as a form of capital punishment, as a result of a traumatic accident, or in connection with murder, suicide, or cannibalism. As opposed to surgical amputation of the limbs, dismemberment is often fatal to all but the simplest of creatures.Dismemberment was carried out in the Medieval era by tying a person's limbs to a chain or other constraint, then attaching the restraint to two separate movable entities (eg. a vehicle) and moving them in opposite directions. Also referred to as "disruption" or being "drawn and quartered", it could be brought about by chaining four horses to the condemned's arms and legs, thus making them pull him apart, as was the case with the execution of Robert-François Damiens and François Ravaillac in 1610. Queen Brunhilda of Austrasia, executed in 613 is generally regarded as having suffered the same death,
