Did I want to see a sample? Yes! The following, appearing in the book, is from a proposal letter that McCrone sent to Fr. Peter M. Rinaldi in 1977. Amazing:
For centuries the Turin Shroud has been a holy relic of the Catholic Church but owned by the Italian House of Savoy. The Shroud rests in a silver chest in the Cathedral of St. John in Turin, Italy. The provenance for the Shroud is known dependably for more than 600 years with considerable evidence extending this date back to the time of Christ.
It would be a tremendous accomplishment if the Shroud could be dated, and a date near the time of Christ would certainly lend considerable weight to the evidence that it is indeed the Shroud of Christ Himself. It is also important to determine the nature of the image on the linen. If the image and the stains that form a part of that image are shown to have been caused by body fluids, this would be further authentication. Finally, success in these two areas (the date and presence of body fluids) would then make it be very difficult not to conclude that the Shroud is indeed that of Christ.
We believe there is an excellent chance that the Shroud can be dated, using very new techniques, and that the chemical nature of the stains can be established. We further believe that this can be done without removing easily detectable samples from the Shroud. We will discuss each of these analytical problems in turn, beginning with the problem of dating very small samples of organic materials such as linen.
So I ordered the book for my dog.
