More often, I think, the "stipes" was permanently situated, whereas the wrists of the delinquent were nailed to the "patibulum" which was laying on the ground. Afterwards all ropes holding the arms were removed, so even a light movent afterwards causes incredible pain, for example when a rope was fixed to lift the victim, who was first forced in a sitting position and then had to use the leg muscles for standing up. Now, with the patibulum on his shoulders, the naked delinquent offered his body for further tortures like kicks, cuts, hot iron, penetrated anus, and when writhing and trembling the agony was multiplicated. When further lifted, the probably screaming victim will hang only by the wounds and may be dropped to the stipes free from the hight of about 30-40 cm, later the feet of the squiirming crucified were nailed flat to the crossbeam, thus causing soon steady muscle cramps...
