Biblical Archeological Review on mysterious images
The editors of Biblical Archeological Review on the problem of the mysterious images:
. . . although radiocarbon tests have dated the shroud to 1260-1390 A. D., no one has been able to account for the shadowy image of a naked 6-foot-tall man that appears on the shroud. With bloodstains on the back, wrists, feet, side and head the image appears to be that of a crucified man. The details - the direction of the flow of blood from the wounds, the placement of the nails through the wrists rather than the palms - displays a knowledge of crucifixion that seems too accurate to have been that of a medieval artist.
