Heretics Fork: The device was placed between the breast bone and throat just under the chin and secured with a leather strap around the neck, while the victim was hung from the ceiling or otherwise suspended in a way so that they could not lie down. A person wearing it couldn&#x27;t fall asleep. The moment their head dropped with fatigue, the prongs pierced their throat or chest, causing great pain. This very simple instrument created long periods of sleep deprivation. - Wikipedia
