Absolutely wrong! The Shroud has been scientifically studied intensely for several years using modern instruments, and there is NO evidence the image was inked in. Your citing Chaucer when there is modern scientific evidence available?
Just it has been widely known that most relics were at best pious frauds.
And the image is made of red ocre and vermillion... vermillion as a pigment was a fairly new at the time that we have actual records of the Fraud of Turin.
