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