Charles Freeman on Tetradiplon and the Video on shroud.com

imageHe wrote in a comment a few hours ago:

… Someone please tell Ian Wilson so that he can revise his text for any new edition of the Shroud. This should go along with his correction of the illustration of tetradiplon as you cannot translate it as ’doubled in four’ alongside an illustration showing it doubled to make eight ( alas a mistake repeated in the video that Barrie has just posted).

Better leave out the tetradiplon issue altogether as it only refers to the cloth BEFORE Christ wiped his face with it and there is no indication in the text that it was refolded as such afterwards. Having ploughed my way through 150 examples of Greek words where tetra was added, the most likely translation is doubled four times- which is exactly the way they folded the Parthenon cloth as seen in the Parthenon frieze in The British Museum. But that would cut through the face of the Man on the Shroud and so would destroy Wilson’s argument. Better just to edit all this out to save Wilson further loss of credibility among the Byzantine experts.

At the Heart of the Shroud Exposition is a Great Mystery

Doubtless Pope Francis will have some arresting and unexpected things to say
when he arrives next month. . . .

imageThe Economist’s blog, Erasmus: Religion and Public Policy has published what I think may be so far the best exposition-time article on the shroud. The Shroud of Turin: Both visible and hidden is fair, perhaps more so than I unfairly expected when I began to read it:

And at the heart of all this activity is a great mystery. The last few popes have spoken of the shroud with awe and encouraged people to contemplate it, but the Vatican has in recent years avoided any pronouncement on whether the cloth really is the one that covered Jesus. In 1988, carbon-dating tests were carried out in laboratories in three countries, and concluded that the fabric had been constructed in the 13th or 14th century; it was a medieval fake. But believers in the shroud’s authenticity point to countervailing evidence: traces of pollen from plants found only in the east Mediterranean, for example. It has been argued that extraneous matter, or radioactivity, could have skewed the carbon-dating results.

To the naked eye, images of the front and back of a slim, dignified man are only dimly visible. But in certain ways, the picture on the Shroud has become more accessible over the past century or so, as it has been subjected to different forms of photographic analysis, and the three-dimensional qualities of the image have been studied. The image does correspond with the Biblical account of a man who was lashed all over his body with a particular kind of whip, commonly used in Roman times, and crowned with thorns which caused heavy bleeding. It also looks clear that the victim was hung up to die after nails were driven through his wrists, not his palms as most religious art would have it. If this was a forgery, it was an ingenious and anatomically intelligent one.

Book Review of the John Klotz’s The Coming of the Quantum Christ

imageIt is a MUST READ, Jack Markwardt’s insightful book review of The Coming of the Quantum Christ—The Shroud of Turin and the Apocalypse of Selfishness by John Klotz.

It’s a must read from the first sentence . . .

Readers drawn to literary efforts which provide both intellectual stimulation and eclectic variety will undoubtedly enjoy The Coming of the Quantum Christ—The Shroud of Turin and the Apocalypse of Selfishness, a delightful concoction blended by its author, John Klotz, from such disparate ingredients as the environment, quantum mechanics, and a world-famous relic.

. . . to the last . . .

In doing so, he has effectively thrown a gauntlet at the feet of his skeptical adversaries, challenging them either to concede that the renowned relic is indeed genuine or to submit a counter-closing argument, based upon relevant probative evidence, which not only establishes its medieval origin but also explains the manner in which its mysterious image was created.


With this review, John Klotz is offering a 15% discount for online purchases of his printed book as a special savings for viewers of shroud.com. You need a special code that will allow you to order the book from Create Space (an Amazon Company) for $39.94 (plus shipping).  No, I can’t tell you what the code is.

Embarrassed Left: Medieval Shroud of Turin Presented to Gullible Masses

Majorettes in Prada-like gear, politicized puppies, even acrobats  &  

shabby rural Catholics who have shown up to adore the Shroud of Turin


clip_image001Indicative, perhaps, of how little anybody cared about it, it took until May 4th for the Huffington Post to cover May Day in Milan and Turin. If that wasn’t enough not-enough, what happened to have not happened was.  Jasmina Tesanovic tells us:

Early in the morning, the traditional May Day demonstration hour for the Turin working class, dark rumor was spreading: Milan is going to go wild, riots just like Baltimore.  A mother confessed: My daughter crept out early this morning to protest against the EXPO in Milan, and I am so worried. Not that I approve of the Expo, but  those protests nowadays run out of control. Yet somebody has to protest.  I used to do it  myself.  It’s her turn now.

Milan? Well:

In downtown Milan, some shops were smashed, banks were trashed and cars were burned. Nobody died, though there were injuries and arrests.  This was classic domestic Italian political violence.  Nobody but Italians is at all upset about Milan staging a big world exposition….

… the next day the Milanese spontaneously cleaned up their city’s riot mess, and life went on, more or less….

Turin?  Well, that is another non-story:

In the Turin May Day demonstrations, all the demonstrators seemed to have found or invented ingenious badges, T-shirts, slogans, or insignia, probably to distinguish themselves from the crowds of pious, shabby rural Catholics who have shown up to adore the Shroud of Turin.  The May Day parade in Turin was quite a show, with beautiful  royal squares and boulevards covered with dignified walking bands, with elegant flag bearers and majorettes in Prada-like gear, politicized puppies, even acrobats. The wary police also sported exotic insignia, with specialized antiterrorist troops, the Alpini mountain battalions, even civilian volunteers in emergency orange gear. 

Turin finds it rather difficult to riot when the city plays host to the pious faithful: the miracle-seekers, desperate souls, youthful catechism classes fresh off the church bus, people on crutches, the sick and the stricken, the people in wheelchairs… Even the Pope is scheduled to show up. He’s rather popular.  No one wants to upset Francis.

Of course a certain "No Expo" sentiment is also present in Torino — it embarrasses the Left that the medieval Shroud of Turin is presented to the gullible masses, a commercialized fake, a literal relic.   But Faith is as blind as Love, and scolding a Shroud true-believer is like telling him his girlfriend is ugly: it just won’t help anything, so why be rude.  This is Italy, after all.

Shroud and Sudarium Blood Agreement

speaking of the meeting of the Centro Internazionale di Sindonologia

imageThis, just appearing on San Francesco, a news outlet of the Sacred Convent of Assisi:  Shroud and Sudarium of Oviedo: "Traces of blood superimposed".  What follows is a Google translation:

‘All information made by the study and research "on the Shroud of Turin and the Sudarium of Oviedo" are in agreement with what, from the point of view of forensic medicine, one should expect that to happen on the canvas with these features if they covered the head of a corpse with all the injuries he suffered Jesus of Nazareth, just as it is told in the Gospels. " This was stated today the Spanish forensic doctor Alfonso Sánchez Hermosilla at the conference of the International Centre Sindonologia which was held today in Turin, dedicated to updates on the "major issues" concerning the Shroud.

It is not a public meeting, but reserved to the members of the Center and this year extended to groups and organizations around the world collaborate with the Turin Centre. Are in fact arrived from France, England, Spain, Peru, Mexico, Brazil and Bolivia more than 300 scholars and experts. "This time," said Gian Maria Zaccone, scientific director of the Museum of the Shroud, "the focus of debate and action, is not the subject of the authenticity of the Shroud.The purpose of the meeting is to review progress on some issues of Shroud research needing further study, such as the role of research palynological and significance of historical research and information on the Shroud. "

Among the experts took the floor also Sánchez Hermosilla, director of EDICES (Group of Investigation of the Spanish Center of Sindonologia), the forensic doctor who continued the studies undertaken in the sixties by Monsignor Giulio Ricci on the Sudarium of Oviedo. "The similarity in morphology and size of the spots of the same with the Shroud of Turin," made him think of Ricci "who had actually found the relic mentioned by St. John" in his Gospel, when he mentions the shroud in the tomb. "From the point of view of forensic anthropology and forensic medicine – continued Sanchez – all information highlighted scientific investigation, are compatible with the hypothesis that the Shroud of Turin and the shroud covered the corpse of the same person ‘ .

The Shroud of Oviedo is a relic preserved in the cathedral of "El Salvador" in Oviedo, Spain, in the House Santa used as a chapel of the palace during the reign of King Alfonso II, an annex to the palace and built with the intention to house the Shroud along with other relics from the king himself. "This painting is located in this region of northern Spain from the year 812 or 842 ‘and’ is packaged in linen; It has a size of about 84 + 54 cm ‘. The textile structure of the Shroud and the Shroud "have the same composition, concretely linen, the same thickness of the fibers are spun by hand and with a twist in the" Z ", although they were woven in different ways: serge spike for the Shroud and why orthogonal (taffeta) for the Shroud. "

In the Shroud it does not appear anything like the mysterious image in the Shroud and prodottasi after the body wrapped in a sheet of blood had stained and fluids. There are in fact only traces of blood and other body fluids "from a human corpse," as he had already said in 1985 Professor Pierluigi Baima Bollone, confirming also that the blood group was AB, as was subsequently confirmed by Dr. José Delfín Villalaín Blanco.

"The morphological study of the spots on the two paintings – said Sánchez – show a clear similarity between them, the cause is due to the fact that the corpse that originated was treated with much care either way." Of course, the Spanish scholar admits, "we must take into account that this morphological similarity between the bloodstains could not be relevant: different heads can give very similar stains, as well as a same head can give very different spots. Nevertheless – he insists – both teams will match very well, if you compare both relics, both for its location and for the surface dimension, to which must be added the correlation distance between injuries that originated stains. "

Hermosilla Sánchez pointed out that the Shroud of Oviedo "hid the face of the corpse," before it was wrapped in the Shroud of Turin. "From the point of view of forensic medicine, it appears a large number of agreements between the injuries that you see in the image Shroud, and those that can be observed in the study of the Shroud of Oviedo criminalistic. Moreover, all these injuries, agree with the findings that, in his day, he realized the STURP through the use of VP8. "

Among the evidence that the Spanish doctor considers most important, we note the bloodstains attributed to the thorns of the crown that "appear in both the relics with a great similarity in the distance separating each other." The area "occupied by the nostril in both paintings is very similar, in the Shroud of Oviedo occupies an area of ​​2,280 m², and the Shroud of 2,000 m². So even in the middle of the right region of the nose is an inflamed area with an area of ​​100 mm² and 90 mm² in the Shroud in the Shroud. "

In addition, one of the spots of the Shroud of Oviedo "seems consistent with some of the wounds caused by flagrum Taxilatum" – the scourge used to hit the man Shroud – "on the right side of the neck, and turns out to be compatible with some of the footprints of the Shroud turin attributed to the same reason. In the occipital region appear bloodstains vital, that spilled when the convict was still alive, are very similar in both paintings and seem to relate to the injuries of the scalp, also it appears to be consistent with those that would produce a crown of thorns ».

"At the height of the 7th cervical vertebra, or vertebra prominens, the Shroud of Oviedo – continues the scholar – a spot appears that takes the shape of a butterfly, and that it could rise as a result of precise stitching canvas Oviedo hair the corpse anointed blood still fresh. This way of sewing the cloth to the hair it produced the form which can be seen in the image Shroud and that some authors believed they identify with a kind of tail or even a braid, providing further proof of the influence that had the use Front Shroud compared to the Shroud. On either side of this spot will appear caused by other fluids cadaverous, and which are similar in the Shroud and the Shroud. "

Sanchez also said that on the Shroud of Oviedo located just a spot appears in the lower left corner of the back of the canvas, "which may have been produced as a result of the outlet of the wound caused by the spear, this spot has its equivalence in the Shroud Turin and could have passed unnoticed until then to its morphological similarity with the spots assigned to scourging. In addition to this spot, appearing indirect signs of the spear, as well as the abundant fibrin clot that appear in the so-called spot and stain spread like an accordion. "

The three-dimensional reconstructions of the face of the man on the Shroud are compatible with the spots in the Shroud. "After knowing the proportions craniometric present in both relics, and once made their comparison, it appears that they are in agreement, what allowed the sculptor D. Juan Manuel Lopez Miñarro to make a reconstruction of the face of the Man of the Shroud . This reconstruction is fully compatible with the face of the Man of the Shroud, not only for his anthropometric proportions, but also in traumatic injuries that have both. "

"In fact, there was also the compatibility of the face once carved, since it is colored in the anatomical regions that are stained with blood in the Shroud of Oviedo, above them was placed a painting very carefully in order to find out, and then check the result; footprints resulting appeared very similar to the canvas of Oviedo. "

Finally, encrusted in a clot of blood from the Shroud of Oviedo, "it turned out a grain of pollen that was morphologically identified by biologist dell’EDICES Marzia Boi as belonging to the botanical genus Helicrisum, and is compatible with other pollens found to be similar Other investigators on the Shroud of Turin. This finding, as well as showing a further analogy between the two relics, could support the hypothesis of Marzia Boi that the pollen could be arrived at tele proceeding ointments which was wrapped the corpse.

The Experts of the Shroud in Conference

That would be the Centro Internazionale di Sindonologia

imageNow, suddenly featured on the home page and listed, undated, on the News page of the Holy Shroud Official Site, is this article:  The experts of the Shroud in the conference from all over the world.  What follows is a Google translation:

Over 300 experts of the Shroud arrived today from France, England, Spain, Peru, Mexico, Brazil, Bolivia to the study conference of the International Centre Sindonologia which was held at the Holy Face. A meeting is not public, but for the members of the Center extended its Italian groups, as well as organizations and research centers from around the world collaborate with the agency in Turin.  "This is our annual meeting – says Professor Bruno Barberis , director of the Center – which normally organize around the feast of the Holy Shroud, set on May 4. " "This time – as set by Sindonologia Center – the focus of debate and action, is not the theme of authenticity the towel. " "The purpose of the meeting – says Professor Barberis – is take stock of the progress of our studies on the Shroud, divided by areas of interest."Some research issues Shroud in particular need of further study, such as the role of ‘ palynological investigation and colors, and the significance of historical research and information on the Shroud.During the work the scholars have been achieved by the archbishop, Monsignor Cesare Nosiglia, papal custodian of the Shroud, which has got to to commend the work. After the meeting they then attended Mass in the Cathedral, celebrated by Monsignor Giuseppe Ghiberti, former president of the Diocesan Commission for the Shroud, and Don Roberto Gottardo, current president of the Diocesan Commission for the Shroud. Finally, the passage before the Shroud for a break of silence and contemplation. "We wanted to take this opportunity Exposition as a ground for closer collaboration – concluded Professor Barberis – Get together around the Shroud confirms the direction of our efforts and represents a moment of great unity.

Very Nice Article About Russ Breault in Baton Rouge Paper

image…by Terry Robinson in the Advocate, Baton Rouge edition. The title is Faith Matters: Fascination with Shroud of Turin lifelong:

“It really does peel back all the science and mystery and the controversy and addresses the question: Could this be the burial shroud of Jesus? Of course, that’s nothing that we can prove in a definitive fashion, but my position based on the evidence is I think it could be,” he said.

Breault, who lives in Atlanta, has presented the Shroud Encounter all over the United States and Canada.

“As someone once said, if this had been the shroud of Julius Caesar, no one would care. But since this is potentially the shroud of Jesus — probably the central figure of human history — that makes it profoundly significant,” said Breault, president and founder of the Shroud of Turin Education Project Inc., which works to raise awareness of the shroud.

Russ is …

bringing his passion and knowledge of the shroud to Baton Rouge. The Shroud Encounter presentation is set for 6 p.m. Saturday, May 9, at Sacred Heart of Jesus Catholic Church, 2250 Main St.

Comment by Hugh Farey on Aging

imageHugh writes in Might tactile chemography prove to be the super-model?:

Some people think that the “effects of aging” are that an originally bright clear image has faded/flaked to what it is now; and others that an originally completely invisible image became visible by darkening – those who habitually place their experiments in an oven for “aging.” We need to be clear about what “aging” really does.

What happens to non-modern linen bleached by different methods, over time under many different conditions: light, temperature both normal and extreme, moisture, natural radiation, all manner of pollutants in the air or in reliquaries and so forth.

There are the questions: do some or all of these things act differently on “imaged” fibers and non-imaged fibers?  How does age act on banding, whatever that is, because it has a visual affect on the image. In fact, is banding a symptom of aging? Why?

Colin Berry: Yes, it’s vitally important to match every tiny detail

Inés San Martín, a Vatican correspondent for Crux has written an interesting article: Is the Shroud of Turin real? Some say it doesn’t matter

Therein we find Joe Nickell saying:

Proponents lack any viable hypothesis for the image formation, and have dismissed re-creations that others have found convincing.

and Barrie Schwortz saying:

Despite being the most studied artifact in history …  modern science is still unable to explain the image or how it was made.

and also saying:

… no one in the past 40 years has been able to duplicate it or create any image with the same chemical and physical properties.

Well, yeah, duh, to what Nickell is saying. In every case there have been problems with the re-creations. It is all about details. That’s why they have been dismissed. 

But then isn’t Barrie’s argument stale. That’s not a criticism of Barrie, it is the situation. Just as we say that no one has figured out how the image was formed – which every student of logic knows is a big fat fallacy – we haven’t figured out anything better to say about the image except what it is not and to keep bringing up those chemical and physical details.

Why?

The Rev. Andrew Dalton, a Legionaries of Christ priest who’s a shroud expert, told Crux that although the Church respects the autonomy of the scientific community, there are details that simply couldn’t have been forged centuries ago.

Details like what?

Isn’t Colin Berry trying to figure out how the image was maybe formed by a forger with Thibault Heimburger reminding him about those pesky little details that “that simply couldn’t have been forged centuries ago.” Inés San Martín should be interviewing them. Here, right out of this blog, let’s look at two comments.

Thibault Heimburger (April 29, 2015 at 3:32 pm):

Colin,

“These aspects of the TS that the new model is supposed to match” are very important.

Your new model, at the end, must match (or at least be compatible with) the fundamental surface distribution properties of the TS: superficiality (at fabric, thread and fiber level), uniformity of the image (no “hot point”, no spot, no “hole”), half tone and fuzzy contours, and bundles of fibers adjacent to uncolored fibers…

Now, if you think that these facts are not proved, despite the many photos you have, I can’t add anything.

If you think that those properties are not important at all, please explain…

The ” ‘scattered colored spots” (also seen in Garlaschelli’s shroud) is only my description of your hand imprint.

I’ll be in Turin until Sunday.

Colin Berry (April 29, 2015 at 10:25 pm):

Yes, it’s vitally important to match every tiny detail of the TS, as it existed when first produced. My new project will attempt to simulate in the kitchen the effect of centuries of subtle degradation on an image of unknown provenance, whether 700 or 2000 years old.

Seriously, TH, one has to recognize the limitations of any attempts at model building. That’s what we scientists, as distinct from physicians, engineers, technologists etc do – we build models. Recognizing the limitations of models, we are concerned primarily with the principles, especially when there are so many who claim for example that a 200nm thick image in unexplainable by conventional science (wrong, it is).

I am not trying to produce a facsimile copy of the TS (forgery Mark 2?) merely to show that its defining characteristics are consistent with medieval forgery. That’s as a counter to those pseudoscientific agenda-pushers who say they are not. (That’s my agenda – anti-pseudoscience). “Defining characteristic” must not turned into a trail (trial?) with no ending.

Hat tip to Joe Marino for sending the Crux article along.

Having Nightmares

clip_image001In an email, Russ Breault writes:

I had a dream last night.  For some reason I was dreaming of Charles Freeman and his painting theory.  I remembered conversations with Isabel Piczek at her studio.  She always develops her paintings, which are large scale murals, with a "cartoon" as she calls it.  I would call it a sketch that becomes the guide for where and how she would apply the paint.  I assume that almost all artists start with an outline, cartoon or sketch.  So in the case of Freeman’s theory, if all the paint has now flaked off, where is the outline?  Where is the underlying sketch? 

First of all, dreaming of Charles Freeman and his painting theory is not merely a dream, it’s a nightmare.

Anyway, when I first read about the shroud, I often read about how the image on the shroud had no outline. Isabel was often quoted and I found myself using the lack of an outline as an argument.  Then one day, I was on Fifth Avenue along the edge of Central Park in Manhattan. There is along this famous avenue, where the sidewalk is as wide as the road, an area where local artists sell their works hanging on a fence or spread out on the pavement. Occasionally, you will find an artist painting portraits of tourists. I watched one such artist at work.  He began with a smattering of seemingly random brush strokes with random colors from his palette. It was, for most of the time that he was painting, a work of pure chaos.  Then the portrait emerged, slowly at first. The was the moment of I think I see the face. Then, it was, of course that is a face. Finally, after maybe ten minutes, it was as hyper realistic as Albrecht Dürer’s self portrait, ca. 1500 AD (above). Watching this artist work was like watching the Harlem Globetrotters. No one shoots baskets like that. No one paints like that, without even a hint of an outline.

But they do. Ever watch Bob Ross on TV?  I’m thinking these days that some artists use outlines and some do not. That the shroud does not appear to have a surviving outline doesn’t impress me all that much any more. Link is https://www.youtube.com/watch?v=VlucWfTUo1A

Computer Generated Young Jesus From Image on Shroud

image

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?

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

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.
