Quite a trick. Did Da Vinci also invent a time machine to create the Shroud 100 years before he was born? Thats what is required since the Shroud first appeared in Lirey, France, in 1352. . . but Leonardo Da Vinci wasnt born until 1452, 100 years later. Lynn Pincknet and Isabel Piznek came up with that cockamamie idea to sell a book and make a documentary to make money. They made their money based on NOTHING. No evidence. Nothing. Zip, Nada. Its Isabel and Lynn in Wonderland!
There are representations of the Shroud with known provenance before the 12th Century and descriptions of it in the 10th Century. So much for Da Vinci and the Shroud.
Please inform of the frauds the shroudies have pulled. I am quite interested as I follow the science and scholarship. I dont give much weight to the people who work outside their fields of real expertise, such as failed stage magicians with degrees in English Literature or Geology telling world class forensic specialists they dont know what they are talking about in physiology, blood science, or people with double doctorates in blood studies that the blood they are working on is really paint. . . especially when the skeptical scientists have never gotten their hands on so much as an iota of a sample to test.
The book explains the early versions as well. Their theory is that the Church approached DaVinci to make a more realistic one than the obvious frauds floating around, which were an embarrassment.
As for their claim of “Shroudie” frauds, I’ll have to find the book and get back to you.
