More Twisted Thinking from Shroud of Turin Proponents

Posted by mattusmaximus on December 22, 2011

I shouldn’t be surprised to see this particular headline at this time of the year: The Shroud of Turin Wasn’t Faked, Italian Experts Say.  It’s just too easy, I assume, for the media to take a story like this and run with it during the Christmas season.  Going beyond the headline, I’d like to analyze a couple of specifics from the folks who are behind this latest “research” on the Shroud.

First, they claim – falsely – that it would have been impossible to fake the Shroud…

… Experts at Italy’s National Agency for New Technologies, Energy and Sustainable Development have concluded in a report that the famed purported burial cloth of Jesus Christ could not have been faked. … [emphasis added]

Which is an interesting claim, based upon the fact that in 2009 researcher Luigi Garlaschelli published his methods for replicating the Shroud using only techniques which would have been available in the 13th and 14th centuries (dates to which all available evidence points as the time of origin of the Shroud).  Here’s what he came up with…

Replications of the Shroud of Turin — So much for the claim that it cannot be replicated (oops)

But the worst part of the analysis by the Shroud proponents comes from the next part of the ABC article:

… According to the Vatican Insider, a project by La Stampa newspaper that closely follows the Catholic church, the experts’ report says, “The double image (front and back) of a scourged and crucified man, barely visible on the linen cloth of the Shroud of Turin has many physical and chemical characteristics that are so particular that the staining which is identical in all its facets, would be impossible to obtain today in a laboratory … This inability to repeat (and therefore falsify) the image on the Shroud makes it impossible to formulate a reliable hypothesis on how the impression was made.” … [emphasis added]

Note the last line there.  It is essentially one big argument from ignorance – that’s what this entire “scientific” endeavor basically boils down to: we don’t know whether or not the Shroud is real, so therefore it really was the burial cloth of Jesus Christ!

So because you don’t know, you know???

Seriously?  That’s the argument?  Using such sloppy logic I could just as easily argue that the Shroud was created by invisible leprechauns, but somehow I don’t think the Catholic Church would go with that explanation.  And that’s the silly thing about arguments from ignorance: once you use such thinking as an acceptable method of argumentation, just about any kind of crazy idea (without any evidence to support it whatsoever) becomes fair game.

If this is the best the Shroud proponents can do, color me unimpressed.

More Shroud Science FAIL

Posted by mattusmaximus on November 22, 2009

The Shroud of Turin has been in the news a bit recently, and I blogged about how it can be replicated using completely natural methods (something many Shroud-proponents say cannot be done – whoops).  Well, now the Shroudies are back, with one of them claiming that she has seen ancient writing on the actual Shroud which “proves” it was the funeral covering for Christ’s burial.

Researcher: Faint writing seen on Shroud of Turin

A Vatican researcher has rekindled the age-old debate over the Shroud of Turin, saying that faint writing on the linen proves it was the burial cloth of Jesus. Experts say the historian may be reading too much into the markings, and they stand by carbon-dating that points to the shroud being a medieval forgery.

Barbara Frale, a researcher at the Vatican archives, says in a new book that she used computer-enhanced images of the shroud to decipher faintly written words in Greek, Latin and Aramaic scattered across the cloth.

She asserts that the words include the name “(J)esu(s) Nazarene” — or Jesus of Nazareth — in Greek. That, she said, proves the text could not be of medieval origin because no Christian at the time, even a forger, would have mentioned Jesus without referring to his divinity. Failing to do so would risk being branded a heretic.

Of course, the claim of “proof” here flies in the face of much other evidence which clearly shows the Shroud’s origins as a pious fraud in the 1300s A.D., way past the burial date of Christ.  This includes evidence from independent radiocarbon dating tests, as well as evidence from historical, iconographic, pathological, physical, and chemical sources that points to its inauthenticity. As one of the foremost skeptical Shroud researchers, Joe Nickell, has concluded: the shroud is a 14th century painting, not a 2000-year-old cloth with Christ’s image.  And, concerning these most recent claims of seeing writing in the Shroud, they are dubious for multiple reasons…

Shroud of Turin: It’s Fake, Get Over It!

Posted by mattusmaximus on October 7, 2009

Well, I can’t say that I’m surprised one bit by this piece of news: there is yet another piece of evidence that the much revered Shroud of Turin is a fake.  But don’t tell the “Shroudies” – those who emphatically maintain that it is the “holy cloth” which covered the body of a crucified Jesus in his tomb – because they’re likely to engage in some rather interesting mental gymnastics via special pleading & cognitive dissonance.

Italian Scientist Reproduces Shroud of Turin

This latest research on the Shroud definitely counters the criticism among the Shroudie-true-believers: that there is no known man-made technique which can accurately replicate the features of the Shroud.  That is because the scientist in question, Luigi Garlaschelli, has perfected a method of replicating the Shroud!

“We have shown that is possible to reproduce something which has the same characteristics as the Shroud,” Luigi Garlaschelli, who is due to illustrate the results at a conference on the para-normal this weekend in northern Italy, said on Monday.

A professor of organic chemistry at the University of Pavia, Garlaschelli made available to Reuters the paper he will deliver and the accompanying comparative photographs.

The Shroud of Turin shows the back and front of a bearded man with long hair, his arms crossed on his chest, while the entire cloth is marked by what appears to be rivulets of blood from wounds in the wrists, feet and side. …

… But scientists have thus far been at a loss to explain how the image was left on the cloth.

Garlaschelli reproduced the full-sized shroud using materials and techniques that were available in the middle ages.

They placed a linen sheet flat over a volunteer and then rubbed it with a pigment containing traces of acid. A mask was used for the face.

The pigment was then artificially aged by heating the cloth in an oven and washing it, a process which removed it from the surface but left a fuzzy, half-tone image similar to that on the Shroud. He believes the pigment on the original Shroud faded naturally over the centuries.

They then added blood stains, burn holes, scorches and water stains to achieve the final effect.
