A Doctor at Calvary by Pierre Barbet

The subtitle reads the passion of Jesus Christ as described by a surgeon. The book describes what we know about crucifixion from history and archeology. It gives a detailed physiological description of the scourge and the crucifixion of Christ from a doctors perspective. It describes the type of suffering a crucified person experiences and how they die. It explains how the body of Jesus would have been taken down from the cross and transported to the tomb, prepared for burial and entombed.

The book is hard to get a hold of because it's out of print.
