Carbon dating and the shroud of turin
It has also been noted that there is a space where the front and back of the head meet, and that what appears to be the outline of the back of the head is a water stain.
The shroud allegedly was in a fire during the early part of the 16th century and, according to believers in the shroud's authenticity, that is what accounts for the carbon dating of the shroud as being no more than 650 years old.
(CNN) -- An Italian scientist says he has reproduced one of the world's most famous Catholic relics, the Shroud of Turin, to support his belief it is a medieval fake, not the cloth Jesus was buried in.
Luigi Garlaschelli created a copy of the shroud by wrapping a specially woven cloth over one of his students, painting it with pigment, baking it in an oven (which he called a "shroud machine") for several hours, then washing it.
"As a hobby I am interested in mysteries, and the Shroud of Turin is obviously a very mysterious object," he said.
He described himself as a rationalist, but said he is not specifically anti-religious.
