"As far as anyone knows..." Ah, but there's the rub. Just a couple weeks ago there was a discussion here about a rabbi stating he had proof Jesus was thrown from a building to his death and I was chastised for even questioning the rabbi statements. Everyone claims they have proof but never have DNA or the full documentation to back up that proof. It would be interesting to take DNA samples of the supposed decendents of Jesus in England and France and compare the results to the head wrap and shroud. And about that head wrap, the shroud doesn't show the wrap.
Jesus had no descendents. He died celibate.
From the link at #64:
Jewish tradition demands that if the face of a dead person was in any way disfigured, it should be covered with a cloth to avoid people seeing this unpleasant sight. This would certainly have been the case with Jesus, whose face was covered in blood from the injuries produced by the crown of thorns and swollen from falling and being struck.
It seems that the sudarium was first used before the dead body was taken down from the cross and discarded when it was buried.
This fits in with what we learn from John's gospel, which tells us that the sudarium was rolled up in a place by itself.
The image indicates that the "man of the cloth" was buried with coins on his eyes. The coins are Roman "leptons," struck, coincidentally, during the reign of Pontius Pilate.
