A medical doctor provides a physical description:
The cross is placed on the ground and the exhausted man is quickly thrown backwards with his shoulders against the wood. The legionnaire feels for the depression at the front of the wrist. He drives a heavy, square wrought-iron nail through the wrist deep into the wood. Quickly he moves to the other side and repeats the action, being careful not to pull the arms too tightly, but to allow some flex and movement. The cross is then lifted into place. The left foot is pressed backward against the right foot, and with both feet extended, toes down, a nail is driven through the arch of each, leaving the knees flexed. The victim is now crucified.
