Crucify means to execute someone by nailing them to a cross with metal spikes. Their hands are stretched out on the crossbeam with spikes driven through their wrists or hands. Their feet or ankles are attached to a cross with a metal spike. The weight of the victim's body tends to force the air out of his lungs. To raise up to breathe, the victim has to put weight on the wounds, and use a lot of strength. The victim is nailed to the cross while the cross is on the ground, then the cross is raised up and dropped into a hole, thus jarring the wounds. Before crucifiction, the victim was usually whipped with a Roman cat of nine tails, which had bits of glass and metal tied to its ends. This caused chunks of flesh to be removed and open wounds to be placed against the raw wood of the cross. The victim was made to carry the heavy crossbeam of his cross from the place of judgment to the place of crucifixion, but often was physically unable after the scourging, so another person would be pressed into involuntary service to carry the cross for him. Roman crucifixion was generally done totally naked to maximize both shame and discomfort. Eventually, the pain, weakness, dehydration, and exhaustion of the muscles needed to breathe make breathing impossible, and the victim suffocates.
