Computer Generated Young Jesus From Image on Shroud

Philip Willan writing in The Times:

Italian police are accustomed to “ageing” photographs of wanted gangsters to help them track down fugitive.

Now they have reversed the process to generate a photofit image of Jesus Christ as a child, using as their starting point the adult man captured in Turin’s famous shroud, believed by many Catholics to represent the face of the crucified Christ.

The computer-generated images were released to mark a two-month exhibition during which the 14-foot-long sheet, normally kept in a sealed container in a chapel next to Turin Cathedral, will remain on public display in the city. Pope Francis is due to visit . . .

Might tactile chemography prove to be the super-model?

April 26, 2015 63 comments

These are early days, but I’m (how shall we say?) quietly confident.

— Colin Berry

imageNo wine before its time.  And don’t read Colin Berry’s posts in his blog before they have aged for a few days to match his unorthodox posting style.  Now is the time. Fine wine indeed if you like something acidic. Give it time to breath. That doesn’t mean, of course, that you or I will like it. It is time to read Might this be how the Turin Shroud was faked, using medieval alchemy?

Colin writes in his blog:

Here it is folks: the best I can offer after more than 3 years  of almost non-stop experimentation : Model 9  ("the nitric acid model").

Alternative name (afterthought, added 25th April): this new technique produces what might be called a "tactile chemograph".  Maybe there was only one ever produced (the image that we now call the Turin Shroud).  The tactile chemograph may be thought of as a forerunner of the photograph. (In both instances, one produces a latent image from a real person without harming them in any way, one that can then be developed in a bath (or vapour chamber) with the appropriate developing chemicals.

There was the moment that Thibault Heimburger asked Colin to “explain in detail the advantages of your new hypothesis with regard to your ‘old’ scorch hypothesis.”  Colin provided ten points. You should read them all. Here are two to temp you:

6. The technique allows for blood (or blood substitute) to be applied at the same time as body-imprinting medium, provided the blood or substitute stays red in nitric acid fumes (real blood does not – it quickly turns a brown colour). Blood would have been applied after. i.e. directly on top of the gooey imprinting medium to account for there being no body image under Shroud “blood”.

and

8. When applied to new linen, the technique has a side-effect that would be seen as a bonus – artificial ageing of the linen. Centuries later, pro-authenticity chemists and others would be delighted to find there was less potential vanillin and more mechanical weakness than would be expected of medieval linen a mere 700 years old.

Jumping to the conclusion (maybe, for there is no predicting with Colin):

The Turin Shroud. was this the world’s first and only tactile chemograph (think of it as a primitive ‘photographic’ negative, except for one tiny detail. Neither light not any other kind of elect6romagnetic radiation played any part in its production. It relied on the human touch (well, gentle massage actually).

What finally persuaded this blogger to abandon thermal scorching, and move to liquid (or semi-liquid) imprinting? It was that paper that Joe Accetta PhD presented at the St.Louis gathering, 2014, in which he propsoed that the TS image had been produced by woodblock imprinting. Up till that time I’d always been sceptical re the use of any kind of liquid imprinting medium, considering that would risk a reverse-side image. But I concocted my own equivalent of Joe’s "oak gall" imprinting ink, in which the iron salts probably have a mordant action, as well as creating the ink by reaction with plant tannins. Here’s an image produced, substituting tannin-rich pomegranate rind extract for oak galls, supplemented with iron (II)sulphate.

That ‘wet’ image was as good, if not better than anything produced by scorching. Yes. there was some reverse-side penetration, but might that not be minimized by suitable modification of technique, or simply by using thicker linen (and the TS linen IS thick, as Hugh Farey has observed).

Once liquid imprinting was permitted as an option, then a host of new experimental options were opened up. Thanks Joe Accetta. You weaned me of those thermal scorches (but they were useful in other ways, showing that ANY negative imprint can model certain key features of the TS, notably negative image and 3D-enhancibility). Models in science do not need to tick all boxes simultaneously. One can run different models in parallel, each earning its keep in one or other respect, while patiently waiting for the day when the super-model suggests itself, one  that combines the best features of its precursors, not only mine, but those of Garlaschelli and Accetta in particular. Hugh Farey and Adrie van der Hoeven added some useful and thought-provoking grist to the mill too, though whether they and the previous two would approve of the end-result is another matter.

Might tactile chemography prove to be the super-model? We shall see. These are early days, but I’m (how shall we say?) quietly confident.

Oh oh! You can’t put the cork back in, can you?

Do go read Might this be how the Turin Shroud was faked, using medieval alchemy?

Flat Earth Society, Shroud of Turin Research Project (STURP) and Other Partisans

April 25, 2015 71 comments

imageTwo days ago, Joe NIckell posted an article, Fake Turin Shroud Deceives National Geographic Author, on the CSI website (formerly known as CSICOP but now CSI,  The Committee for Skeptical Inquiry).

Joe begins:

When a great magazine like National Geographic speaks, the world naturally listens. We were especially glad this is so when—for its March 2015 cover article, “The War on Science”—it cited such attacks as those on climate change, evolution, vaccinations, and genetically altered food, as well as the moon landing. “Thanks, National Geographic,” we said (2015) in our magazine, Skeptical Inquirer.

And yet science—and truth—have since come under attack by an online article that bears the imprimatur of National Geographic. Written by Frank Viviano, the article “Why Shroud of Turin’s Secrets Continue to Elude Science” (2015) is so misleading, so replete with falsehoods, so lacking in basic facts about the notorious “shroud” that it is an affront to the proud name of National Geographic.

It is also a glaring example of how not to approach a controversy. Just as one would not get information about the curvature of the Earth from the Flat Earth Society alone, one should not primarily get “facts” about the Turin cloth from The Shroud of Turin Research Project (STURP) and other partisans. STURP’s leaders served on the executive council of the Holy Shroud Guild, which is devoted to the “cause” of the reputed relic. Viviano tells us in glowing terms of the “scientific disciplines” covered by STURP, without being aware that it lacked experts in art and forensic chemistry. We shall see presently why this matters, but let’s first look at the shameful portions of the shroud’s history that Viviano shamelessly omits.

And Joe concludes:

Scholarship and science have proven the Turin “shroud” a fake, from its incompatibility with first century burial cloths and procedures, its lack of historical record, and a bishop’s report that the forger had confessed, to the suspicious-looking “blood” that is really tempera paint, pigments making up the body image, and the radiocarbon dating that confirms the cloth originated at the time of its documented appearance in the fourteenth century—when it was fraudulently claimed to the be Holy Shroud of Christ. Such evidence against any secular object would be considered clear proof of inauthenticity.

Frank Viviano’s article is a disservice to science and unworthy to appear under the respected name National Geographic.

Of course, Joe is the model for unbiased information. Visit joenickell.com by clicking on his picture.

Student Newspaper Article About the Shroud

April 24, 2015 1 comment

imageThere is an interesting perspective on the shroud by Nathanael Jones in Southern Accent, the student newspaper of Southern Adventist University, a Seventh Day Adventist school. The article is  What the Shroud of Turin and you have in common:

As the school year comes to a close and it’s time to start summer ministries, I was looking for a bit of new inspiration. Where is God? How can I know He’s with me? How can I see Him, know for sure that I’m not taking part in a make-believe ministry?

According to the Wall Street Journal, this past Sunday the Shroud of Turin was displayed for the first time in five years. The Shroud is a Catholic relic that they believe to be the burial cloth of Jesus Christ. Over 1 million people reserved tickets to see it and the Pope has plans to pray in front of it in the coming months.

“Relics are proof that God shared our history,” said Paul Badde, a well-known Catholic author.

All of this got me thinking about whether protestant Christians have proof that God shared our history, since we don’t keep physical relics of God’s Holiness on earth, and if we do, what it is?

[. . . ]

To my way of thinking, there is a bit of misunderstanding about Catholics, Protestants in a broader context, the shroud as a relic and the meaning of proof. But I like the measure and spirit of the article.
