My opinion it is if this Shroud is not the Holy Mandylion looted by the Crusaders from Constantinople then it is a copy of the Greek church's Holy Mandylion from Constantinople.

I consider those two options quite plausible, the first more plausible than the second. Like I said, my opinion is that it's either authentic or a copy of something that was authentic, leaning heavily toward authentic.

Thank you. That was my whole point in the first place. This relic called the Shroud of Turin may very well be the that relic which the Greek church called the Manydlion. If it is a copy (and I prefer copy to forgery) it was a highly skilled work and that kind of copy could only come from the Byzantine workshops. And I must stress again - copies were not viewed as forgeries - they were authentic ways of duplicating relics so they can be transported. There are several relics claiming to be shrouds or cloths with the image of Jesus on them.

Byzantine reports mention "one original and two copies".
