Context: In his book The Crucifixion of Jesus, physician and forensic pathologist Frederick Zugibe studied the likely circumstances of the death of Jesus in great detail. Zugibe carried out a number of experiments over several years to test his theories while he was a medical examiner. These studies included experiments in which volunteers with specific weights were hanging at specific angles and the amount of pull on each hand was measured, in cases where the feet were also secured or not. In these cases the amount of pull and the corresponding pain was found to be significant.
