The Shroud of Turn Research Project

The French researcher who published this article is Tristan Kazabianka. He goes into all the details as a fascinating story. The bottom line is that they use a sample from the top left corner of the shroud, which we know to be anomalous. It's just not representative of the rest of the shroud. They lumped them together and gave us this big arc 1260 to 1390, 95% sure that this is the time period from which the shroud hails. And so it's fake.
