First, thanks for your extraordinarily informative response. Even where I disagree, still much appreciate & enjoy it.
Now, on Wikipedia -- I always turn to Wikipedia first, because it invariably represents "conventional wisdom," and more often than not, "conventional wisdom" is as good as we can get. In other words, where Wikipedia is wrong, it's usually because a awful lot of people are also wrong.
In this example, I don't defend Wikipedia except to say that many people apparently don't know the facts. Seems that someone more knowledgeable might work on re-writing that Shroud article?
"Several researchers have stated that, under enhancement, the outline of a small phylactery appears to have been attached to the forehead between the eyes. This is the "open square" or "U" above the bridge of the nose in the image."
I see it now.
"That U or Square has been commented as appearing in many Iconic images that are thought to be created in the image of the Man on the Shroud such as the Christ Pantocrater."
Here is the oldest known Christ Pantocrater, from St. Catherine's Monastery, Mt. Sinai:
Compare to:
Compare to Zeus at Ephesus:
"...all related to forensic proportional body size tables, were presented in peer-reviewed science published actual measurements of the image on the Shroud put the height of the man at about 174cm ±2cm (5'8.5" +/-1")."
I'll take that as authentic.
"From the comparison among the anthropometric indices characteristic of different human races with those of the Man of the Shroud it was possible to point out that the Semitic race is the closest one to the characteristics obtained. "
Not sure how to take that -- note the word "possible."
