QUOTE : Crucifixion was a widespread and exceedingly common form of execution in antiquity, one used by Persians, Indians, Assyrians, Scythians, Romans, and Greeks. Even the Jews practiced crucifixion; the punishment is mentioned numerous times in rabbinic sources. The reason crucifixion was so common is because it was so cheap. It could be carried out almost anywhere; all one needed was a tree. The torture could last for days without the need for an actual torturer. The procedure of the crucifixion—how the victim was hanged—was left completely to the executioner. Some were nailed with their heads downward. Some had their private parts impaled. Some were hooded. Most were stripped naked. It was Rome that conventionalized crucifixion as a form of state punishment, creating a sense of uniformity in the process, particularly when it came to the nailing of the hands and feet to a crossbeam.
