Ordeal by fire was one form of torture. The ordeal of fire typically required that the accused walk a certain distance, usually or a certain number of paces, usually three, over red-hot ploughshares or holding a red-hot iron. Innocence was sometimes established by a complete lack of injury, but it was more common for the wound to be bandaged and re-examined three days later by a priest, who would pronounce that God had intervened to heal it, or that it was merely festering—in which case the suspect would be exiled or put to death. One famous story about the ordeal of ploughshares concerns Edward the Confessor's mother, Emma of Normandy. According to legend, she was accused of adultery with Bishop Ælfwine of Winchester, but proved her innocence by walking barefoot unharmed over burning ploughshares.
