A small question" HOW could it be faked? So far no one has been able to replicate the shroud. Even a medieval artist armed with en camera techniques. would have also have to be armed with techniques we don't know about in order to make something like this.
A small question" HOW could it be faked?
Don't know. That's why I suggested commissioning an art forger to try to make a fake shroud. Maybe nobody who knows what they're doing has tried the experiment before. This is the same idea as getting a professional magician to investigate people claiming to be mind readers or spoon benders or faith healers (James Randi's specialty).
Would it work? Maybe, maybe not.
