Joe had commented in Cat Among the Pigeons:
Some clarifications about the order and circumstances of the invisible reweave theory.
We did not start out with the Quad Mosaic photos when we first presented our theory in 2000. We had shown some experts photos that included a very high-quality photo of the C-14 area that’s in the excellent book by Gino Moretto (of the Shroud Museum in Turin) called Shroud Guide. It was only brought out in 2008 in the Chemistry Today article from 2008 and the presentation made at the Ohio Shroud conference that year.
Regarding the experts we showed it to, one was Thomas Ferguson & Co. Ltd, world-renowned makers of Double Damask Linen, another was Louis Harner of Albany International Research Company, and the third was European-trained weaver David Pearson, owner of the French Tailors in Columbus, Ohio, who was very familiar with the French invisible reweave technique. I will leave it to others to decide if the fact that they aren’t academics is significant.
Going back to the Quad Mosaic, there’s a very fine article on Barrie’s site about it at http://www.shroud.com/pdfs/quad.pdf, with some important comments by the late Jean Lorre, an imaging expert from the Jet Propulsion Laboratory in Pasadena, California.
