New Garlaschelli and Borrini Study

April 11, 2015 117 comments

imageThere is a new study out by Matteo Borrini, professor of forensic anthropology at John Moores University in Liverpool (UK), and Luigi Garlaschelli University of Pavia, that argues against the authenticity of the shroud. The following is a Google translation from Italian of a UAAR (Union Atheists Agnostics and Rationalists) press release posted in the A Good Reason blog by the UAAR and reposted in AgoraVox:

Press Release:  Shroud: new studies call into question the authenticity: 

imageThe imprint of the body on the Shroud does not match that of a condemned posted in a location similar to the classical representations of the crucifixion. And not even that of a bloody body lying in the tomb.

These are the findings of new studies by Matteo Borrini, professor of forensic anthropology, now at John Moores University in Liverpool (UK), and Luigi Garlaschelli University of Pavia, that for this research has obtained a contribution of the AU.

The work, presented by Borrini at the Conference of the American Academy of Forensic Sciences in Orlando (USA), confirms the findings already last year by a similar study of the two teachers.

As known, the image of the Shroud of Turin are visible, in addition to the faint image of a body, even trace amounts of (alleged) blood resulting from the wounds of passion on his forehead and neck, on the chest, on the feet, and finally on the back of one hand and on the front of the forearms, from wrist to elbow.

The scope of work of Borrini and Garlaschelli was to verify – using forensic techniques of BPA (Bloodstain Pattern Analysis – analysis of the shape of the blood stains) – what should be the posture of a human body so that the rivulets of blood you have as it appears on the footprint human in the Shroud of Turin.

A thin cannula for transfusion, connected to a bag of blood, was applied to the dorsum of the left hand of a volunteer in three different positions of possible leakage of the nail, in agreement with the most common assumptions about the exact anatomical location of the wound as it follows from the Shroud.

In previous studies, the forearm was kept at different inclinations with the aid of a goniometer ballistic – 0 °, the horizontal arm, 90 °, vertical arm – and a modest amount of blood had been made on the back of the hand casting and along the forearm.

All tests had shown that in order that the stream of blood flowing on the outside of the forearm, as visible on the shroud, the angle of the arm itself must be greater than 80 ° and less than 90 °, and then placing it in a position almost, but not totally vertical.

The new tests now conducted have considered other aspects:

  1. The arms were always placed vertically, even with hands over his head, to play the position assumed if the condemned had been crucified in a single vertical pole.
  2. To simulate the hypothesis that the bleeding had occurred (perhaps by a body washed) after death, blood was dripped from the back of the hand of a volunteer lying with his hands on the pubis in the same position of the Man of the Shroud ( both legs stretched that flexed). In none of these tests has achieved a performance of rivulets similar to that seen on the Shroud.
  3. Scholars have finally run a BPA for the wound to the right side. A sponge (of the same size of the alleged injury readable on the shroud) soaked synthetic blood was pressed through a special grip on the torso of a mannequin standing. The trend trickles result in this case is vertical, consistent with that from image front of the Shroud of Turin. However doing the bleeding experimental with dummy lying (for groped to reproduce leaking from image ridge of the Shroud, which also derives from the wound to the chest for bleeding post-mortal), the result was quite different.

Taken together the results of these tests are therefore not consistent with the general trend of the rivulets of blood on the Shroud of Turin and seem to refuse to testify in favor of their authenticity, but rather in an artistic or didactic.

What’s to like over on Colin’s blog right now?

Making Joe Accetta’s idea work?

imageWhat is there to like in the experimentation being live-blogged in Can that weird and wonderful Turin Shroud be modelled? See my hands-on results with dye-imprinting, reported in real time?

Well, for one thing Colin is experimenting, not simply speculating. When Luigi Garlaschelli produced his manufactured images, he was immediately criticized for failing to match many if the shroud’s image characteristics. Luigi had failed. Colin is aware of that and he is taking the image characteristics into account. It is appropriate to note, however, that all of the image characteristics are not completely unchallenged; for instance, how certain are we that there is no image beneath bloodstains? Colin is aware of those issues, as well.

He begins this way:

For background, see the posting immediately preceding this one. It attempts to explain my switch in focus from the ‘scorch’ model to that proposed last year by Joseph Accetta – based on medieval dye imprinting technology. I’ve extended and embellished it a bit, but as the title indicates, this post is about getting ‘hands-on’ experience with dye impriinting off 3D templates, with a view to getting familiar with the pros and cons of the Accetta model, vis-vis the scorch model.

imageThe posting ends this way (at least for now, there is no way of knowing when a post ends with Colin):

Oh dear. This is the reverse side, photographed straight afterwards, and already one can see bleed-through, despite the presence of that thickening agent. Late addition: the gum arabic was then left to evaporate in air until a treacly consistency, that was then painted onto the crucifix. despite the higher viscosity than used with dye, there was immediate bleed-through to the reverse-side of the linen.

Gum arabic is, sad to say,  NOT the answer if one’s attempting to achieve contact-side imprinting only. Maybe there are alternatives that need testing, but they have to fulfil a number of criteria yet to be discussed in detail.

Maybe one needs to test a starch dispersion, or colagen glue from boiling animal bones etc? Suppose it imprinted well, with minimal bleed through. Suppose it was then prone to flaking off with ageing and/or handling, leaving that fainter ghost imagewhich is what we may be seeing today. There’s still work to be done. But first I must report the results of testing out a different scenario by which a ghost image could have formed, one that results in a modification of superficial linen carbohydrates, based on the premise that alum and/or iron sulphates used as mordants could have generated sulphuric acid that at sufficiently high local concentration to react chemically to produce changes not dissimilar to those obtained by thermal means (contact scorching). For that, the experiments moved from kitchen to garage, involving as they did a degree of hazard.

Shroud: The Reasons for the ‘No’

February 11, 2015 99 comments

imageMaria Chiara Strappaveccia, Culture Columnist, has an interesting article in L’Lindro entitled Sindone: le ragioni del ‘no’: Le obiezioni all’autenticità del Telo sintetizzate da Andrea Nicolotti, Luigi Garlaschelli, Antonio Lombatti

(or as Google Translation puts it, Shroud: the reasons for the ‘no’: The objections to the authenticity of the Cloth synthesized by Andrea Nicolotti, Luigi Garlaschelli, Antonio Lombatti)

Here is a rough Google translation of the article:

What are the reasons why many in the debate on the Shroud of Turin, lined up for the authenticity of the Shroud? 

  • There is not reason to believe that the Shroud is medieval?
  • [Is it] true that it is irreproducible?

During the creation of this special dedicated to the Holy Shroud, in view of ‘ exposition of April , we spoke with many scholars of the Cloth, between the so-called ‘non autenticisti’ we discussed, among others, with historians Andrea Nicolotti , scholar of the history of Christianity and researcher at the University of Turin, and Antonio Lombatti , Popular University of Parma, and the chemical Luigi Garlaschelli , Professor of Organic Chemistry at the University of Pavia. From conversations with Garlaschelli and Nicolotti (that for our Special realized some services that will be published in the coming weeks), we extracted a summary of the ‘reasons for not’ the authenticity of the Shroud.  

Archaeology and History

The linen threads of the Shroud have a twisting opposite to that in use in Israel at the time of Jesus; this twisting, however, is the same that was used in Europe in the Middle Ages. Then the shroud is not a fabric produced in Palestine at the time of Jesus .

The flax is woven with the technique twill from 3 Alloy 1, that is, each warp yarn passes over three weft yarns and under the fourth, and so on , alternately, so as to form a diagonal pattern. This trend is mirrored and gives rise to an effect to ‘zig zag’ said ‘herringbone’. It is not known in ancient times , before the Middle Ages, no linen fabric large and complex as the shroud that has been woven with this technique , with which the frames would have been at the disposal of the old extreme complexity to the point of making it almost impossible. No ‘ shroud ‘ and no linen fabric ancient comparable to the shroud is made ​​in this way . The oldest examples found so far, which are technically comparable to the Shroud are all back to the thirteenth century.

The Shroud of Turin is completely different from the various fragments of authentic Palestinian shrouds of the first century known to archaeologists, found in tombs at Masada, ‘En Gedi, Jericho, Akeldama.

It seems that the real shrouds were wrapped around the body and tied , and not placed above and below , and stir well stretched in the longitudinal direction, as seems to be the case for that of Turin. The Shroud is not even consistent with the description of the Gospel , which speaks of various linens and a shroud on the head, smaller and distinguished from other fabrics. Also the Gospels do not say that Jesus was put in a sheet , but that was wrapped and tied in cloth, which is incompatible with what you see in the Shroud of Turin , where there are no signs of ligatures and windings .

The Gospels do not mention no human footprint that would remain etched in the burial cloth of Jesus.

The Shroud of Turin is not known from the first century , in fact, for several centuries, no one ever said that the burial cloth of Jesus had been saved and preserved . It is likely that the Jews of Jesus’ followers have not even touched, because for the Jews of that time as to those of today that has touched a corpse is impure and transmits impurities.

The Shroud of Turin does not resemble any of the shrouds that, from the sixth century AD, began to be described by many pilgrims who visited the holy places and knew the various relics, today recognized almost all false, that they began to be produced at ‘era. It is highly unlikely that a genuine relic with an image of Christ as the Shroud was never mentioned by anyone until the Middle Ages .

The Shroud of Turin is by no means a relic of ancient and unique, because before it appeared there were other ‘shrouds’ elsewhere and most well-known and revered (Rome, Constantinople, Jerusalem, Compiègne, Aachen, Cadouin, Mainz, etc.) , all considered authentic until the modern era.

The Shroud of Turin suddenly appeared in France , in Lirey , in the diocese of Troyes, towards 1355. Immediately Henri de Poitiers , the bishop of the local diocese of Troyes, which was opposed all’ostensione made, considering it an obvious fake. The exhibitions resumed after about thirty years, and yet the new bishop, Pierre d’Arcis , opposed. After a long standoff between him and the dean of the church where the exhibitions took place in 1389, the bishop appealed to Pope Clement VII with a long memorial, in which he tells how his predecessor had even found the artist that ‘ had ‘cleverly painted’.

The Pope allowed the exhibitions only as long as you say every time that it was a representation, and not the true Shroud of Christ. At the time of these fights anyone, neither the Pope , nor the bishops , nor the canons of Lirey neither the owners of the Shroud never claimed that it was true , indeed, everyone called ‘figure’ or ‘representation’ of the true shroud of Jesus .

The luck of the Shroud began only when it was illegally sold to the Duke of Savoy from a woman who died excommunicated for his action. Because of the power of the ducal family, slowly were forgotten and hidden the little noble origins and initial controversy, through a work of falsification of the history of the Shroud that lasted until the early twentieth century. Once in their hands , the Savoys increasingly promoted the cult , as a relic of the royal family, to obtain the endorsement of some popes declared , from Julius II .

Among the thousands of medieval relics (thorns of the crown, wood and nails of the cross, sandals and robes of Jesus, fragments of his umbilical cord of his foreskin, his hair and more), the shrouds, certainly not lacking. Generally were white sheets, as the Gospels do not mention any impression on them. But there were also small towels called ‘Veronica’ or ‘Mandili’, which, according to various legends, Jesus would have left imprinted on his face alive. Perhaps the union of the two concepts of miraculous imprint and shroud, especially from Veronica, who was born the idea of a shroud bearing the imprint of the entire body. 

The image and the wounds

Considering the Shroud image is known the total lack of geometric deformations that would be expected from an imprint left -with any means- by a human body covered by a towel . Several researchers have tried to cover a voluntary colorful painting , and appoggiargli over a sheet . Obviously the result is a horribly deformed, and no halftones and nuances of the real Shroud, but rather a ‘stamp effect’. The image of the Shroud, which seems so perfect, it is absolutely unrealistic: too good to be true .

Abused and inconsistent is the reference to the alleged special ‘ negativity ‘ of the Shroud image , ‘discovered’ in 1898 when the Shroud was photographed for the first time. The discussion on this point also coincides with the birth of the Shroud. In fact the shape of the body presents a reversal of light and shade than the reality ; parts of the body more in relief, those that should be more exposed to light (such as the nose), on the fabric are darker, while those less in relief, and then further away from the fabric and less illuminated by the light (as the orbits eyes) are less dark. This has nothing strange nor means that the author was so clever to know the effect of modern photographic negatives, as often claimed: it is simply the result of a normal decals , just what an architect would have wanted to make to give the ‘impression of a contact between a tissue and a body capable of leaving an image (bloody because, for example).

Many sindonologists ‘autenticisti’ (the terms are in fact become almost synonymous) were and are coroners. In their view, the precision pathologic of wounds and injuries on the Shroud are completely realistic and compatible only with a real corpse. In fact any investigation of a medical nature on a figure stamped and in the absence of the true body is extremely speculative and based on unprovable assumptions . It is evident, however, that are not at all the pretty plausible dripping blood on the hair (which if anything should essersene matted and soaked), nor the existence of an imprint hair themselves , that a person would fall backwards without lying trace on the front side. It has also been experimentally verified that the direction of true dripping blood on the forearms, on the backs of the hands and side follow trends quite different from those depicted on the Holy Cloth. But are the laboratory analyzes those mentioned by now discussed more frequently; for instance as to the presence or absence of blood. Obviously, on a false shroud could find blood, dyes, or both; but a shroud true-even if it had been doctored with colorimetric must necessarily possess traces of blood. A first commission of inquiry set up by Cardinal Michele Pellegrino gave in 1969-1973, however, disappointing results. The forensic analysis laboratory of Professor Giorgio Frache Modena (test chemical, chromatographic and immunological) had only negative results . Microscopic examinations conducted by Guido Filogamo and Alberto Zina showed no traces of red blood cells or other blood corpuscles typical. We saw, however, the granules of a coloring material whose nature there is pronounced. It should also be noted that the ‘ blood ‘ on the shroud is still very red , while it is well known that normally the degradation of hemoglobin makes it very dark in a short time .

In 1978 the then Archbishop of Turin Cardinal Anastasio Ballestrero (assisted by Professor Luigi Gonella Turin Polytechnic as a scientific consultant) allowed 120 hours of analysis in a group self-offertosi of American scientists, the STURP (Shroud of Turin Research Project ), which underwent a series of test chemical, physical and spectroscopic on which even today is discussed.

In contrast with previous results, the chemical STURP John Heller and David Alan Adler said to have established the presence of blood because they had got the typical reactions. In 1980, however, the well-known American microscopist Walter McCrone on fibers that STURP had passed he found no blood, but traces of red ocher, vermilion (red pigment widely used in the Middle Ages) and Alizarin (plant pigment red-pink). McCrone reported, moreover, the presence of a binder for the pigment particles that saw, which could be collagen (gelatin), or egg white. In practice it would tempera paints. The intrinsic characteristics of the image, proven by scientists STURP, are very interesting. L ‘ image is superficial (does not pass on the other side of the sheet) and is not produced by pigments or dyes    -a difference of blood stains, knead that the entire thickness of the canvas with a substance that bonds the fibers, and they are visible red particles. The image is due to a yellowing of the cellulose fibers , in practice to a degradation due to dehydration and oxidation. Analyses STURP indicated that body image has properties very similar to those of the burns , still clearly visible, that the Shroud suffered in the fire in 1532. Both the hypothesis of a slight burn (or singeing) than that of a chemical attack were deemed plausible , although the STURP failed to explain the genesis of an image with these characteristics, which lead many to exclude the work of an artist.

Sindonologists insist that an image with these characteristics can not be achieved with the means available to a medieval craftsman. They therefore concentrate all their efforts to find supernatural mechanisms that explain the genesis. The assumption, however, is not acceptable. Various hypotheses have been put forward on how the Shroud was manufactured (eg using chemical or heat) that certainly would be more easily found on the original, if access is not prevented by its owners.

The radiocarbon

The STURP , among others, recommended the radiocarbon dating of the relic by the method of carbon-14 to settle the question of authenticity. Only ten years later, in 1988, Cardinal Ballestrero and Gonella, under the supervision of the Pontifical Academy of Sciences, chose the three laboratories with more experience in this technique worldwide: Tucson, Oxford and Zurich. Coordinator was Professor Michael Tite of the British Museum, considered a prestigious institution above the parties. Small samples were taken from a corner of the cloth, and the overall results , published October 13, 1988, circumscribed the age of the cloth to the period between 1260 and 1390 .

This means that the radiocarbon dating has fully confirmed the historical data (the Shroud appears suddenly in the middle ages, not before) and technological (the kind of fabric is not attested before the Middle Ages).

Cardinal Ballestrero proved to accept and adapt to the results of the test honestly: " I think it is not appropriate to question the results. Nor is the case of reviewing the skins scientists if their response does not square with the reasons of the heart . " Who did not give the response of independent scientists were the advocates of authenticity to the bitter end, which imbastirono various lines of objections. Some delusional (conspiracy of laboratories with complicity Ballestrero), other laughable (collected fragments of a mending -obviously ever seen by any of the various textile experts who examined the Shroud wire instead of the pro-Shroud). The hypothesis most often repeated is that the levy was polluted by dirt consists of carbon more ‘modern’ that would have rejuvenated the cloth, but this is a topic that does not convince anyone of those who deal with radiodatazioni.

In 1993 a Russian chemist immediately became famous, Dimitri Kouznetsov , stated that during the fire suffered by the Shroud in Chambéry in 1532 the carbon dioxide of the air would be fixed to the cellulose of the linen, making carbon ‘recent’. A careful reading of the works of Kouznetsov showed, however, errors and forcing. Attempts to scientifically reproduce his experiments failed one after the other. But only after careful investigation it was discovered that it was a real quack, who had also invented names of collaborators, magazines, museums and laboratories.

It should be noted that none of the three laboratories of radiocarbon dating has never confirmed the objections of the Shroud. It should also be pointed out that radiocarbon dating is a tried and tested tool for archaeological dating, which each time has been applied to an alleged relic of Jesus provided a medieval dating (Shroud of Oviedo, title of the cross, the shroud of Carcassonne, tunic of Argenteuil, etc.) always rejected by the supporters of these relics.

Other statements ‘wonderful’ of ‘autenticisti’ -fungi grown on the fabric, traces of Roman coins from the time of Pilate, written in various languages ​​[in] visible on the cloth, pollen ancient Middle East, prior to the fourteenth century miniatures depicting the Shroud – are, similarly, not very plausible.

You might try a Bing translation. I could not get it to work.  Google did what seems to be a good job but with some loss of formatting.  I’ve tried to fix that in places.

Put that in your pipe, Luigi Garlaschelli, and smoke it

. . .  I nominate Colin Berry as the best, most qualified, most creative scientist skeptic in the history of the shroud.

I agree. Put that in your pipe, Luigi Garlaschelli, and smoke it.  What was the name of that Chuck Berry song? “Roll Over McCrone”?  No, Joe Nickell only wears a white lab coat like all the other PhDs in English Lit.

And I’m thankful for Colin’s work. And I’m enjoying his new explorations in the area of Maillard Reactions using lemon juice and milk.

Now, I’m not saying he isn’t wrong about a lot of things. I think he is.

And he can be something of a junk yard dog at times.

And I still think the shroud is the burial shroud of Christ. Who knows, maybe Colin will prove me wrong some day. Maybe he’ll come around to my way of thinking.

No, that is not a picture of Colin. It is Luigi. For a picture of Colin visit Colin’s About Me page in Blogger

Moreover, I trust Colin. He doesn’t want me to quote the following paragraph from his very public blog. But it says a lot, so let him be pissed. It is one reason why I trust him:

. . . There is no such thing as an expert in the field of sindonology (or shroudology as I prefer to call it. We are all beginners. Some begin better than others. The TS is a test of our ability to separate the wishful thinking that comes with appealing imagery from that of cold hard reality. Sadly there is no part of the human mind that is devoted to detecting CHR. The human mind is programmed to respond on a more immediate like/dislike response to what it sees. It’s part and parcel of the human condition to instantly add layers of fancy to what cunningly or otherwise seduces, or attempts to seduce the eye.

Maybe he’ll come around to my way of thinking? Probably not, but I think he is honest. Thanks, reader, for writing.

A couple of years ago you wrote a parody of an article about Luigi Garlaschelli. I am preparing a lecture on the Shroud and was thinking of using the fake article as a humorous handout. I have not been able to locate it. Do you have a copy that you can send to me.

Actually, it was five years ago. As I read it now I am embarrassed. It was kind of stupid (nah, maybe it was a bit funny). Here is the boring original news story from Reuters. In tracking it down I found this lead up link to it in PZ Myers’s Pharyngula, unquestionable the leading New Atheists blog out there. Here, below the line, is what I wrote (undoubtedly late at night sitting alone in some Jimmy Buffet Margarita Ville bar that I can’t remember. Feel free to use it. And there is no need to give me the credit.

ROME (Reuters) – An Italian scientist says he has reproduced a human being, a feat that he says proves definitively that humans, which Christians say are made in the image of God, are medieval fakes produced using materials and techniques that were available in the middle ages.

A scientifically-made mannequin, measuring 6 feet, 2 inches tall, looks eerily like Luigi Garlaschelli, the scientist himself.

"We have shown that is possible to reproduce something which has the same characteristics as a human being," 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 mannequin resembles the back and front of a bearded man with long hair with his arms crossed on his chest. He has two hands, two feet and a single head with two eyes and two ears.

Since Darwin, evolutionary biologists have believed that humans evolved along with other animals and plants from a common ancestor. But scientists have thus far been at a loss to explain why some people smoke cherry flavored pipe tobacco since it offers no evolutionary advantage.

Garlaschelli, who received funding for his work by an Italian association of atheists and agnostics, expects people to contest his findings. “They didn’t believe me when I reproduced the Shroud of Turin, Quantum physics and the Egyptian pyramids, thus proving that they, too, were medieval creations. “

“It works for me,” said PZ Myers, pastor of the Morris, Minnesota Pharyngula Church of Fundamentalist Atheists. “I was getting tired of evolution, anyway. I believe everything I read in the newspapers so long as it doesn’t conflict with my beliefs. If humans are manmade, that’s fine. I still don’t need to believe in God.”

Garlaschelli said the funding for his work by his own organization of like-minded atheists had no effect on his results. "I always start with results," he said. “That way, I always arrive at the desired conclusion.”
