Excellent 3D artist’s depiction of Crucifixion.
Someone young and healthy could suffer in the most horrendous agony for two or three days on the cross. Even if given the prescribed 39 lashes with one of the most severe whips ever devised by man, the Roman “Flagellum.”
The Flagellum had small pieces of bone and metal knotted into the leather thongs of the whip and could easily flay the skin and flesh of those it was used on.
