LOL!
I'm curious about how the medieval forger matched the blood type (AB, occurring in 3% of the population) with the Eucharistic miracle of Lanciano and the Sudarium of Oviedo. That's a pretty cool trick.
Also, the image-bearing fibers of the Shroud were scorched, not painted.
Like I said, most of the critics here are ignorant of the facts and are involved in Catholic or Christian bashing.
No, Aquinas, the images are not a scorch... the chemistry of the image is now well understood and it is neither a scorch nor a daubing or a painting. It is a coating on the uppermost fibers of the image area composed of starch fractions and saccharides:
. . . the Shroud of Turin's images are the result of a very natural, complex chemical reaction between amines (ammonia derivatives) emerging from a body and saccharides within a carbohydrate residue that covers the fibers of the Shroud of Turin. The color producing chemical process is called a Maillard reaction. This is fully discussed in a peer-reviewed scientific journal, Melanoidins, a journal of the Office for Official Publications of the European Communities (EU, Volume 4, 2003).
If they were scorches they would fluoresce just as the scorches from the 1532 fire flouresce.
