Peine forte et dure (Law French for "hard and forceful punishment") was a method of torture formerly used in the common law legal system, in which a defendant who refused to plead ("stood mute") would be subjected to having heavier and heavier stones placed upon his or her chest until a plea was entered, or as the weight of the stones on the chest became too great for the condemned to breathe, fatal suffocation would occur.
The common law courts originally took a very limited view of their own jurisdiction. They considered themselves to lack jurisdiction over a defendant until he had voluntarily submitted to it by entering a plea seeking judgment from the court. Obviously, a criminal justice system that punished only those who volunteered for punishment was unworkable; this was the means chosen to coerce them.
Many defendants charged with capital offences nonetheless refused to plead, since thereby they would escape forfeiture of property, and their heirs would still inherit their estate; but if the defendant pleaded guilty and was executed, their heirs would inherit nothing, their property escheating to the Crown. Peine forte et dure was abolished in the Kingdom of Great Britain in 1772, although the last known actual use of the practice was in 1741. In 1772 refusing to plead was deemed to be equivalent to pleading guilty. This was changed in 1827 to being deemed a plea of not guilty. Today, in all common law jurisdictions, standing mute is treated by the courts as equivalent to a plea of not guilty.
The elaborate procedure was recorded by a 15th-century witness in an oft-quoted description: "he will lie upon his back, with his head covered and his feet, and one arm will be drawn to one quarter of the house with a cord, and the other arm to another quarter, and in the same manner it will be done with his legs; and let there be laid upon his body iron and stone, as much as he can bear, or more ..."
The most famous case in England was that of Roman Catholic martyr St Margaret Clitherow, who (in order to avoid a trial in which her own children would be obliged to give evidence) was pressed to death on March 25, 1586, after refusing to plead to the charge of having harboured Catholic (then outlawed) priests in her house. She died within fifteen minutes under a weight of at least 700 pounds (320 kg). Several hardened criminals, including William Spigott (1721) and Edward Burnworth, lasted a half hour under 400 pounds (180 kg) before pleading to the indictment. Others, such as Major Strangways (1658) and John Weekes (1731), refused to plead, even under 400 pounds (180 kg), and were killed when bystanders, out of mercy, sat on them.
The only death by peine forte et dure in American history was Giles Corey, who was pressed to death on September 19, 1692, during the Salem witch trials, after he refused to enter a plea in the judicial proceeding. According to legend, his last words as he was being crushed were "More weight", and he was thought to be dead as the weight was applied. This is referred to in Arthur Miller's political drama The Crucible, where Giles Corey is pressed to death after refusing to plead "aye or nay" to the charge of witchcraft. In the film version of this play, the screenplay also written by Arthur Miller, Corey is crushed to death for refusing to reveal the name of a source of information.
In medieval Europe, the slow crushing of body parts in screw-operated "bone vises" of iron was a common method of torture, and a tremendous variety of cruel instruments were used to savagely crush the head, the knee, the hand, and, most commonly, either the thumb or the naked foot. Such instruments were finely threaded and variously provided with spiked inner surfaces or heated red-hot before their application to the limb to be tortured.
