I also agree with Daveb. He summarises the evidence that counters a medieval date for the shroud admirably, and uses, entirely reasonably, words like “ambiguous” and “unproven”, and explains that he is persuaded of authenticity. I, on the other hand, am not persuaded of authenticity. I think that’s fine. The Shroud will not become authentic, or medieval, on the basis of what Daveb or I am persuaded, and it is good that together we can work towards removing some of the ambiguity of the evidence, whichever way it leads.
The “also agree” is agreeing with John Klotz who packed it into six words:
As usual, Daveb says it all.
And what Daveb said:
Until proper representative sampling is carried out in accordance with a valid sampling protocol, the validity of the results from the single grab sample in 1988 must remain ambiguous and debated, whatever the cause might be of the mismatch from an earlier date, in view of other indications that the Shroud is the authentic burial cloth of Jesus of Nazareth. These indications may include: 1) Fanti’s mechanical testing suggesting the possibility of a 1st century date; 2) Historic arguments that the Shroud was in Constantinople in 1204; 3) Indications from the Hungarian Pray manuscript that distinctive features of the Shroud were known in 1195, prior to the alleged C14 dating; 4) Forensic arguments that the image is that of a real crucified person who suffered the punishments reported in the gospels including a crown of thorns and percussio wound to the chest; 5) the otherwise inexplicable cause of the image; 6) the unsmeared blood stains; 7) Presence of Jerusalem limestone; Etc, etc!
The assertion of homogeneity of the cloth remains unproven, in light of reputable assertions of occasional mending, and in that case a single grab sample is insufficient, even though it might be a routine practice for testing of other cloths (e.g. mummy wrappings) for which there would be no cause to presume mending. Rogers, whatever shortcomings there might be in his chemistry knowledge, and also reputed to be an agnostic, was the chemist with the greatest familiarity with Shroud chemistry. His investigations persuaded him that there were anomalies indicative of highly skilled mending.
Should perchance representative sampling demonstrate that the single grab sample was in fact adequately representative of the whole, then some other explanation for this peculiar result might then have to be considered. The forensic arguments, together with the enigmatic cause of the image, seem to me to be particularly persuasive of authenticity.
I’m not sold on numbers 1 and 6, but I am sold overall. And I think that the historic argument is much more than Constantinople in 1204. I find the Hymn of Pearl very persuasive, for instance.
That Rogers might have been agnostic doesn’t weigh on me. And if it did, it might impress on me a measure of objectivity. However, Joan Rogers, Ray’s wife, has publically stated in the past that they were both Protestants.
