"Such total involvement got its reward especially in his [Hall’s] participation in the dating of the Shroud of Turin in 1988 … `There was a multi-million-pound business in making forgeries during the 14th century,’ he bluntly told a British Museum press conference. `Someone just got a bit of linen, faked it up and flogged it.’"
and then in telling us:
… And in a sense Hall was right! If the Shroud were a medieval forgery, then the forger, to maximise his profit, would have "just got a bit of linen." That is, he would have used the least expensive "bit of linen" he could find that would still deceive his prospective buyers (and that wouldn’t require much-see #3). But the Shroud is not just any "bit of linen." As we have seen above the Shroud would have been expensive and rare in the first century. And it would have been even more expensive and rare in the 14th century, of which there is only one known other example, but in fragments as opposed to the ~4.4 x 1.1 metre Shroud. So the medieval forger would have been most unlikely to have obtained a fine linen herringbone twill sheet the size of the Shroud in the first place.
