Another Overwhelming Evidence Argument?

a wide loom, which existed in the Roman Period but not in the Middle Ages

Stephen Jones has just about wrapped up one of his drawn out, serialized postings (he is nine tenths of the way done, he tells us) that are part of his overwhelming evidence drumbeat. Perhaps I should have waited a couple more days for him to finish the posting. But he was drifting away from the main thrust of his argument. Because he had moved from discussing the cloth’s selvedge into a rehash of his outlandish and obsessive conspiracy theory that the carbon dating results for the Shroud of Turin were manipulated by a computer hacker who was probably working for the then Soviet KGB, I concluded that his posting was finished. His posting is out there on his blog and finished as far as I was concerned.

The subject of the post is that the selvedge is overwhelming evidence that the Turin Shroud is authentic. His conclusion:

Problem for the forgery theory. This is yet another part of the problem for the forgery theory, that the Shroud is not medieval (see #1,#3, #4, #5). As we saw above, the two selvedges running down the lengthwise borders of the Shroud prove beyond reasonable doubt that: 1) and the main body of the Shroud and the sidestrip were evidently cut lengthwise from a larger cloth and then joined to form a composite cloth which became the Shroud, with the combined dimensions of 8 x 2 Assyrian standard cubits (see also Dimensions #3); 2) the cloth that the Shroud and sidestrip were cut from had evidently been woven on a wide loom, which existed in the Roman Period but not in the Middle Ages; 3) the sophisticated weaving and tailoring of the Shroud points to it having been manufactured in a textile `factory‘ which are known from Roman period Egypt and Syria but not from the Middle Ages; and 4)the unusual stitching, binding and finishing of the selvedges is, like the stitching of the seam joining the sidestrip to the main body of the Shroud (see Sidestrip #5), known only from the first century Jewish fortress of Masada.

So the shroud could not possibly be medieval?  But aren’t 1, 2, 3 and 4 debatable?
