Latest on carbon dating the shroud
(Another equally famous painting, also claimed to have miraculously appeared on a cloth, cropped up in Mexico in the 16th century, "Our Lady of Guadalupe.") The case for the forged shroud is made most forcefully by Joe Nickell in his Inquest On The Shroud Of Turin, which was written in collaboration with a panel of scientific and technical experts."All empirical evidence and logical reasoning concerning the shroud of Turin will lead any objective, rational person to the firm conclusion that the shroud is an artifact created by an artist in the fourteenth-century."The "shroud" of Turin is a woven cloth about 14 feet long and 3.5 feet wide with an image of a man on it.Actually, it has two images, one frontal and one rear, with the heads meeting in the middle.It is also claimed that the image is not a painting but a miraculously transposed image.Skeptics believe that the shroud of Turin is just another religious relic invented to beef up the pilgrimage business or impress infidels.
A weight of 20th century carbon equaling nearly two times the weight of the Shroud carbon itself would be required to change a 1st century date to the 14th century (see It may interest skeptics to know that many people of faith believe that there is scientific evidence which supports their belief in the shroud's authenticity.Of course, the evidence is limited almost exclusively to pointing out facts that would be true the shroud were authentic.It has been noted that if the shroud were really wrapped over a body there should be a space where the two heads meet.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.
To non-believers, this sounds like an ad hoc hypothesis. The suggestions that modern biological contaminants were sufficient to modernize the date are also ridiculous.
