I read some articles on the most recent medieval find of a document stating the Shroud of Turin is a forgery. I could not find any indication of what was so obvious to Pope Clement the VII and to Nicole Oresme. Did they name the forger or the technique used to produce the Shroud? I assume it must have been obvious to both of them. I also read that someone confessed they created the forgery but I see no names. Here is a link: [700-Year-Old Medieval Document Is the Oldest Written Evidence to Claim the Shroud of Turin Is Fake](https://www.discovermagazine.com/a-700-year-old-medieval-document-is-the-oldest-written-evidence-to-claim-the-shroud-of-turin-is-fake-47982) . Perhaps a separate question but of equal interest to me and I may post as another question were the samples used on the Carbon 14 dating from a repaired area with some fibers being medieval origin? I read this has been refuted but am not sure of the source. I also read about a husband and wife team ( Bedford and Merino? ) in Columbus who found the fibers were repaired and this was substantiated by someone on the STURP Team who had a left over sample in his lab. He subsequently passed away. I may have stepped over out of bounds asking two questions in one note.

I did some reading but cannot say for certain I understand. Imagine the fiber is a cylindrical object. Does the stain cover the upper most fiber for 360 degrees around the fiber extrior? And does the back of the Shroud contain the same discoloration 360 degrees around the upper most fiber?
