I have to disagree in part to correct a misstatement. There is no facial image on the Sudarium of Oviedo, only blood stains. These stains, and a bloody hand print, however, do bear seventy-two points of congruity with blood stains on the Shroud of Turin. 21 points of congruity is considered a perfect match in fingerprinting. I know. These are not fingerprints.
It is my contention that after the Sudarium was used to cover Jesus head on the cross and while carrying him to the tomb, it was further used by rolling it diagonally into a rope like form and then used to tie "around" his head, passing under his jaw and beard, behind his forelocks and ears, and then tied at the top of his head to keep his mouth closed in death to prevent gaping as part of the bindingsthe other bindings being those needed to keep his arms and legs from flopping after rigor passedthus meeting the statement about the cloth that was "wrapped around his head" that was left apart from the other graves clothes. It was this rolled and tied Sudarium that Jesus pulled from around his head as he walked from the tomb and dropped on his way out. . . a very natural act, freeing himself from the binding around his head.
I have tested this hypothesis with a cloth cut to the exact rectangular dimensions of the Sudarium preserved at Oviedo. When rolled diagonally along the hypotenuse of the 84cm x 53cm Sudarium the resultin "binding" is almost exactly one meter at 99.3cm, which is more than enough to wrap under the chin around behind the ears and then be tied at the crown. The Sudarium has repeated blood stains showing that it was rolled in just such a manner while some of the blood was still fresh enough to transfer across the roll.
Thank you for the correction.
