Re that wrongly named Shroud of Turin: let's try rewriting STURP's deplorable 1981 Summary ...





Above is a screen grab of the  1981 STURP SUMMARY  (available on the site of STURP's Documenting Photographer)


CLICK TO ENLARGE!


Below is my annotated version, showing how  I think it should have been presented, given the yawning gaps and uncertainties in the data, given the blind spot for the negative image, given the infatuation with 3D-rendering software, given the tunnel vision where alleged yellowing of largely inert cellulose is concerned as a mechanism for creating the body image ...

STURP's original: black font. My preferred version - blue italics!

STURP Summary

No pigments, paints, dyes or stains have been found on the fibrils. X-ray, fluorescence and microchemistry on the fibrils preclude the possibility of paint being used as a method for creating the image. Ultra Violet and infrared evaluation confirm these studies. 

No conventional pigments, paints, dyes or stains have been found on the fibrils.  X-ray, fluorescence and microchemistry on the fibrils preclude the possibility of  an artist's paint  palette playing a role in creating the image.  Ultraviolet and infrared evaluation confirm these studies. 

What cannot be ignored is the negative (tone-reversed) nature of the body image. Artists would hardly elect to paint a subject as a negative unless wishing to suggest the image had been IMPRINTED onto the linen. But a better more convincing representation of an imprint is obtained, not with freehand brush, loaded with paint, but by actual IMPRINTING. How? Answer: by coating the subject from head to foot with a suitable imprinting agent, and either pressing subject onto linen, or, more probably,  vice versa - by pressing linen down firmly onto the subject!

(Note: nowhere does the STURP Summary make any mention whatsoever of (a) the tone-reversed negative  or (b)  the likelihood of a negative image having been acquired via imprinting- as distinct from painting . Bizarre! Truly bizarre! ) 

Computer image enhancement and analysis by a device known as a VP-8 image analyzer show that the image has unique, three-dimensional information encoded in it.

Computer image enhancement and analysis by a device known as a VP-8 image analyzer show that the  2D image  responds well to 3D-rendering computer software. However, that is equally true of imprints generally, and indeed any 2D figure or graphic with variations in image intensity, the latter being elevated  proportionately onto an imaginary z axis.  That is not say there won't be distortions etc, especially where paintings and photographs are concerned, due largely to shadowing (equally responsive as main image to 3D software!).  Summary: the 3D-response contributes nothing to one's understanding as to how the body image was produced.

 Microchemical evaluation has indicated no evidence of any spices, oils, or any biochemicals known to be produced by the body in life or in death. 

 Microchemical analysis has failed to detect the presence of any spices, oils, or indeed any biochemicals known to be produced by the body, either in life or in death. 

That could be seen as further evidence against the Linen being a burial shroud, whether authentic or simulated, and by default, supplies circumstantial evidence in favour of it as Joseph of Arimathea's actual transport linen, or more probably a  medieval mock-up thereof.

It is clear that there has been a direct contact of the Shroud with a body, which explains certain features such as scourge marks, as well as the blood. 

It is clear there has been a direct contact with a body - or a facsimile thereof - given the dimensions, negative image etc. 

Features such as blood and scourge marks, while serving to reinforce that impression, need to be treated with caution: none of the blood stains, scourge marks included, display any indication of torn or punctured skin in the body image, and may accordingly have been applied separately, either as genuine blood, artificial blood, or a combination of the two, not necessarily simultaneously (e.g. either real or artificial blood as later touching up to restore or enhance colour, given that blood darkens with age).

However, while this type of contact might explain some of the features of the torso, it is totally incapable of explaining the image of the face with the high resolution that has been amply demonstrated by photography.

One noteworthy feature deserving of comment is the imprint of the face: it displays a superior definition than the rest of the body, even if some aspects are distorted - notably a flattened  and somewhat distorted nose. 

It is possible that the imprinting procedure for the face differed from that used elsewhere.  Reasons? One can only speculate, but if the body image was of medieval fabrication, as seems likely (see above), a compromise was reached between conveying the notion of a  seemingly realistic  albeit somewhat fuzzy whole body imprint left in age-yellowed sweat and blood to signal a victim of crucifixion, while communicating greater detail in the face alone to signal that it was indeed a particular victim of crucifixion with beard, moustache, shoulder length hair etc.

The basic problem from a scientific point of view is that some explanations which might be tenable from a chemical point of view, are precluded by physics. Contrariwise, certain physical explanations which may be attractive are completely precluded by the chemistry.

Omit - lacking specifics

 For an adequate explanation for the image of the Shroud, one must have an explanation which is scientifically sound, from a physical, chemical, biological and medical viewpoint. At the present, this type of solution does not appear to be obtainable by the best efforts of the members of the Shroud Team. 

Omit - lacking specifics

Furthermore, experiments in physics and chemistry with old linen have failed to reproduce adequately the phenomenon presented by the Shroud of Turin. 

Omit - lacking specifics

The scientific concensus is that the image was produced by something which resulted in oxidation, dehydration and conjugation of the polysaccharide structure of the microfibrils of the linen itself.  Such changes can be duplicated in the laboratory by certain chemical and physical processes. A similar type of change in linen can be obtained by sulfuric acid or heat. 

The most immediate and obvious recipient of the body image is the linen itself, comprising mainly cellulose, but with minor components as well (hemicelluloses, lignin etc).  

Endowing cellulose with colour is not easy, needing not just dilute sulphuric acid to model in the test-tube, but concentrated  acid (both a powerful chemical dehydrating agent as well as oxidizing agent as well - if hot)- but scarcely realistic or credible. 

So a question mark needs to be placed over chemical modification of the major linen component, and by the same token, heat alone.  In the context of medieval fabrication, in which an imprinting medium may have been deployed, consideration needs to be given to extraneous non-linen components. Candidates? One can but speculate.

However, there are no chemical or physical methods known which can account for the totality of the image, nor can any combination of physical, chemical, biological or medical circumstances explain the image adequately.


There is a possible clue that might guide future research. It is the finding that the body image fibres are bleachable with any of three different chemical reagents - namely diimide, hydrazine and alkaline hydrogen peroxide -  all having something in common (they interrupt colour-conferring conjugated systems of single and double bonds in organic molecules). Firstly that finding should  serve to exclude from consideration inorganic paint pigments referred to earlier. The chromophore is organic, i.e. carbon-based. Dr.Walter McCrone please note!

Thus, the answer to the question of how the image was produced or what produced the image remains, now, as it has in the past, a mystery.

The question as to how the image was produced or what produced the image remains a matter of speculation unless or until that is we have more detailed chemical information on the nature of the body image chromophore. 

Modified cellulose? Improbable!   Maybe a type of extraneous addition  to the linen that lends itself better to introduction of conjugated double bonds, maybe via thermal  or chemical input, and thus development of yellow coloration. Melanoidins?  (High molecular weight   i.e. particulate solid  endproducts of complex Maillard reactions between reduciong sugars and amines involving repeated chemical condensation and polymerization). 

We can conclude for now that the Shroud image is that of a real human form of a scourged, crucified man.

We can conclude that the Shroud image is a representation of the crucified Jesus, imprinted onto Joseph of Arimathea's transport linen. Authentic (1st century)? Or a medieval simulation thereof?  The essential next step is radiocarbon dating.

 It is not the product of an artist. 

It is not the product of an artist (but possibly/probably that of one or more medieval artisans who have deployed whole body imprinting, using an unknown imprinting medium, maybe heat or chemically-assisted to generate a faint tan colour as if ancient age-yellowed sweat.

The blood stains are composed of hemoglobin and also give a positive test for serum albumin.  

The blood stains appear to contain hemoglobin and also give a positive colorimetric test for serum albumin, based on dye-binding.

The image is an ongoing mystery and until further chemical studies are made, perhaps by this group of scientists, or perhaps by some scientists in the future, the problem remains unsolved.

Insufficient data are presently available to identify the image chromophore with certainty, or even to rule in or rule out chemical modifcation of the cellulose or some other linen constituent. 

 Further chemical studies are required. All one can say with certainty is that the chromophore relies on conjugated double bonds for its colour (thus accounting for the bleaching action of the three highly specific double-bond targeting reagents): inorganic paint pigments can be firmly excluded.


If  I had to sum up the '81 STURP Summary in just two words, what would they be?

Answer: woolly obscurantism... yet we're told  recently by STURP's Documenting Photographer (now STERA President and the owner of the shroud,com site)  that it was a model for good science, a shining example for us modern day scientists to follow! 

Er no. The project was shot through  from the word go with  preconceptions and inner contradictions.  (Like later claiming that contact imprinting was out of the question,  that it was imprinted  photograph-like across air gaps, due to lack, we're informed, of inescapable lateral distortion, despite the body image having no sides!

Photo Gallery to follow! (Yes, this posting is a work in progress)



Photo Gallery



Fig 1 : Left:  a negative image of my own hand (but NOT a photograph in the first instance - merely recorded as such for posterity).
  Right: the same image after tone-reversal (which can be achieved either by photography or via digital computer software).

So how was the initial negative image captured, if not by photography? Answer: as a CONTACT IMPRINT. I simply wetted my hand, and pressed it down onto dark-coloured fabric.
 (Note the absence of so-called "lateral distortion" which we were told by STURP's Director precluded imprinting by contact in the case of the so-called Shroud of Turin. Nonsense! Complete and utter nonsense! One simply keeps the sides of the imprinted item away from the cloth: no side contact, no lateral distortion!)



Fig.2:  Performance of those hand imprints of mine (negative and tone-reversed positive) in modern-day 3D-rendering
software (ImageJ)

Observe that both the original negative and the tone-reversed positive display a 3D appearance after applying the 3D software. The 3D-rendering is due to the software - not the input image. All the latter has to do is supply variations in  2D image intensity, no matter how acquired.
The claim in the '81 STURP Summary that the so-called Shroud of Turin body image displays "unique encoded 3D" is also total nonsense. That fallacious claim is trotted out even now,  nearly 40 years later as if established fact. Nothing could be further from the truth. Shame on you STURP for foisting your pseudoscience on the world at large, and continuing to do so, such of you as are still around...




Fig.3: Here's another negative image, again of my hand, and its tone-reversed positive.  But on this occasion it was  not by liquid  - which tends to spread too far - but by SOLID imprinting, using powdered charcoal. Note the near photograph-like quality of the imprint!


Might a powder have been used to capture the body image on the so-called Shroud of Turin?  I say YES!  Which powder? Answer: plain white flour, as used for breadmaking.  How was the yellow colour produced?  Answer: via heat-treatment of course (roasting the imprinted linen in an oven, or even over the glowing  red hot embers of a flame-free open fire).

Fig.4: Here are some flour imprints of my hand (not my best, not my worst) obtained with two different variants of the imprinting technique:



(For some reason the following stays red in red font, despite several attempts to replace red with black!) 
The one on the left employed a thick slurry of flour in water. That on the right was obtained by dusting the oil-smeared hand with dry flour,  shaking off excess flour, then imprinting onto wet linen. Both imprints were then developed with heat to generate the negative images as Maillard browning products.
 Note the different character of the two imprints as regards overall definition, sharpness of image boundaries etc

Fig.5:  Here's an imprint of my face, obtained using the wet slurry technique.



No heat development was needed: photoediting alone was sufficient to enhance the natural faint yellow colour of plain white flour:

Who says the nose makes it impossible to imprint the face?  Not if one presses hard to flatten and distort the nose - as appears to have happened to the nose of the Man on the Linen!

Fig 6:  contact imprint from a miniature plastic figurine, just 14cm in size, obtained via the dry-flour imprinting technique onto wet linen followed by heating of the imprinted linen.





Observe absence of any "lateral distortion" of the image. Why? Because the figurine was first smeared with vegetable oil, and the flour then sprinkled vertically from above, making scarcely if any contact with the sides (which could have been wiped off had that been the case).   As before, the flour imprint was heated in an oven to develop the colour of the negative imprint. The  negative, tone-reversed image you see is, I consider, a miniature of that on the Turin Linen, obtained via essentially the same procedure. In short, it is wrong for numerous websites to claim, as they do, that the body image on the so-called Shroud continues to elude science, 40 years post that hugely flawed STURP investigation . No it does not. It is easily explainable as a contact imprint, one  whose colour has been developed by thermal means.


Fig.7: Imprinting with sweat and blood (whether authentic or 14th century simulation) not a new idea:

See this paper by Dorothy Crispino, with its reference to Cardinal Gorrevod implicating sweat and blood as early as the late 15th century: 




Fig.8: Indeed, the idea of imprinting by contact immediately after descent from the cross, and receiving into Joseph of Arimathea's "fine linen" (whether with bodily sweat,  or possibly anointing oils - see pot in foreground) was taken up by early painters, notably Roviere in the 16th century:





So what happened to cause the  immediate post-crucifixion First Day imprinting narrative  to be summarily dismissed, and be replaced by supernatural Third Day resurrectional auto-photography (mediated we're told by a burst of corpse-generated radiation). 

Answer: look to STURP, notably its Director and prime initiator, John Jackson PhD  plus colleagues, and their allegedly cause-and-effect correlation of image intensity with "cloth-body distance".

Fig.9:



The key sentence in the above paper is this one:  "The frontal image on the Shroud of Turin is shown to be consistent with a body shape covered with a naturally draping cloth in the sense that the image can be derived from a single global mapping function of distance between these two surfaces".

Yes, but stating something to be consistent is not the same as demonstrating a real cause-and-effect relationship. Most if not all textbooks of statistics include a warning about the the danger of spurious correlations (my Yule and Kendall back in the 1960s illustrated with a graph showing a near perfect correlation between year-on-year increase in alcohol consumption and that of schoolteachers' salaries!).

There is an alternative explanation for the APPARENT correlation between image intensity and cloth-body distance, measured on a subject with loosely-draped linen.  It's the model that's wrong, assuming that loosely-draped linen. See my earlier 2018 posting on the subject, one in which linen is pressed firmly down on the subject, with imaging at the contact points ONLY!

Fig.10: Quickie comparison of two rival imaging models: 





(A) the quasi-photographic model of Jackson et al  featuring pro-authenticity loosely-draped linen, permitting imaging across air gaps, see red pointers,  albeit weaker; (B) the  non-authenticity medieval-imprinting model, strictly imaging-by-contact only, where prominences like the nose are subject to greater contact pressure , see yellow pointers, to permit  physical contact with lower relief.

Click on the above link to the Chicago-based McCrone Research Institute, and what do you find?  Be prepared for a surprise. Correction - a cobweb-festooned 40 year old surprise that should  by rights have departed gracefully  from the literature decades ago!




Fig 12:  Yes, McCrone, or rather his survivors, are still maintaining that the tan-coloured body chromophore is "red ochre", i.e. inorganic iron oxide, Fe2O3, would you believe it?

Here's a copy of an email I sent the McCrone Research Institute 6 days ago (blue font, thus far no reply or acknowledgement):


Title: Er, why do you continue to promote your founder's fallacious iron oxide paint pigment claim re Turin Shroud body image?

From: sciencebod01@aol.com>
To: info@mcri.org>
Date: Fri, 16 Aug 2019 


Hello folks

I've just been reading, correction, re-reading your founder's views  re that so-called "Shroud", still prominent in Google rankings.

They start with this statement:

"The faint sepia image is made up of billions of submicron pigment particles (red ochre and vermilion) in a collagen tempera medium. The pigments red ochre and vermilion with the collagen tempera medium was a common paint composition during the 14th century; before which, no one had ever heard of the Shroud."

I can understand the image chromophore being mistaken for iron oxide  (aka red ochre) 40 years ago. But why is that view still being promoted?

40 years ago,  STURP's Adler and Heller showed that the image chromophore was organic, i.e. carbon-based, through being bleachable by reducing agents (diimide, hydrazine, alkaline hydrogen peroxide) that act on conjugated C=C double bonds . One cannot expect an inorganic metal oxide like Fe2O3 to be bleached by any of those three agents!

So why continue to promote an early misidentification, even if understandable at the time?

I personally (a retired PhD biomedical scientist) have been researching the so-called Shroud for well over 7 years. I too believe it to be of medieval manufacture, but NOT a painting (instead a roasted organic whole-body negative IMPRINT, where the final sepia-coloured chromophore is almost certainly a mix of high molecular weight melanoidins, as first proposed by STURP's Chemical Director,  Raymond N.Rogers).  However, I consider your founder was correct about one thing - in identifying the chromophore as solid and microparticulate (sub-micron in size).  

So how about publishing an updated version of your founder's message, ensuring that his particle microscopy does not get dismissed through having been over-hasty with the chemistry?

Let me know if you would consider a joint paper between myself and your research institute as an updated corrective. 

Do you by any chance still have any of Walter McCrone's image fibres from 1978? If so, they could be the basis for a new round of microscopy - focused on the precise location of the body  image chromophore (which I maintain to be inside the SCW cores, not restricted to the PCW as maintained by modern-day sindonologists, keen to promote their miraculous pro-authenticity image-formation mechanisms (corona discharges, uv pulsed laser beams, sub-atomic particles, earthquakes etc etc).

Kind regards

So then, what is the way ahead assuming (a) Turin allows a limited STURP Mk2 (?) and (b) it it's restricted, as before, to - at best - individual image fibres,  maybe dissected out with a blade rather than contaminated with sticky tape?

Answer: not easy, given the likely paucity of specimen for analysis. As before, microscopy would seem to bw the best bet, also given priority in STURP Mk 1 with the dispatch of Rogers'  stripped-off sticky tape sample to microscopist Walter McCrone in the first instance.   However, what mustn't be repeated in a second round is the exclusive focus, at least initially, on microscopy, unaided by microchemistry.  (Thank goodness for Adler and Heller's later testing, notably the  image bleaching studies,  when they finally received samples from McCrone).

So is there a straightforward, previously omitted chemical test that can be applied to image fibres, not to exclude iron oxide (already performed, hat tip to Adler and Heller) but to confirm Rogers' alternative to oh-so-speculative prematurely-aged cellulose, namely those high molecular weight Maillard browning products, aka melanoidins?  I wish I could say there was, but years of literature searching have failed to unearth a simple or even involved test for those pesky entities we call "melanoidins" (read: chemical Mount Everest).

So what's the stand-in solution(s) where any STURP Mk2 is concerned?

There are two that come to mind.

The first is to acquire some tentative evidence at least for a melanoidin chromophore.  Methodology?  Still at the planning stage, maybe exploiting two known properties of melanoidins: (a) their anionic character - due to negative electric charge (carboxyl groups?) and (b) linked to that same anionic character, their ability to bind metal ions, which might  conceivably be exploited to develop a colorimetric or fluorimetric test.

Fig. 13: Here's what I consider might be a useful and potentially informative way forward worth considering for STURP Mk 2. It's a graphic from a posting I did way back in late 2012:




Cellulose, the incredibly resistant polymer that makes up the bulk of the plant kingdom (as cell walls) CAN be dissolved, or at any rate disaggregated as semi-solubilized. How? By adding a solution of copper (II) hydroxide in excess ammonia, which contains the Cu (NH3)4 ++ ion ("cuprammonium ion". What's more, the cellulose fibres can be re-precipitated, merely by acidification.

So how might that chemistry come in handy? It was McCrone's belief that the body image chromophore on the Linen was in the form of minute sub-micron particles, and while his attempts to identify those particles as iron oxide came to naught (and rightly so)  Raymond N.Rogers later offered an alternative more credible explanation - the particles comprise high molecular weight melanoidins , i.e. Maillard browning products.  This scientist will go one stage further and propose that those particles are locked away inside the cores of the SCW (secondary cell wall) of linen fibres. How did they get there? Answer: by entering the fibre cores as a liquid at high temperature, released from roasting white flour imprint, whereupon that liquid then rapidly polymerised and became entrapped in the SCW cores. That's what McCrone saw through his microscope!

Testing the hypothesis: take image-bearing fibres from the Linen. Disperse in the cuprammonium reagent to "dissolve" the cellulose of the SCW, releasing the chromophore particles. Spin off those solid micro-particles to separate from the solution. One then has free liberated chromophore that can then be tested with this or that chemical reagent - or examined with one or other physical technique - in order to pinpoint more precisely the chemical nature of the chromophore.

Fig.14: Here's a pair of graphics  I posted in 2017 to the International Skeptics Forum site, greeted with much derision  (that, namely derisive catcalling,  being the speciality of that now abandoned site !).



Why? Because I deployed a filter available in Windows 10 called "Zeke". What it does is to accentuate anything that is already particulate in nature,  whether body image or blood, allowing it to stand out better from background (artefactual maybe, but useful nonetheless - a kind of contrast-enhancement tool).

Fig.16: As stated elsewhere on many occasions, this investigator believes that the Linen with its imprinted image (as if left on Joseph of Arimathea's 'transport' stretcher) was inspired, nay prompted,  by the pre-mortem Veil of Veronica. Here's a few lines from the wiki entry:

"During the fourteenth century it  (the Veil of Veronica ) became a central icon in the Western Church; in the words of art historian Neil Macgregor: "From [the 14th Century] on, wherever the Roman Church went, the Veronica would go with it." The act of Saint Veronica wiping the face of Jesus with her veil is celebrated in the sixth Station of the Cross in many Anglican, Catholic, Lutheran, Methodist and Western Orthodox churches."

There's a large number of artistic representations of the Veil. I've chosen just one.





Note the way the face responds to 3D-rendering in ImageJ software!  "Unique encoded 3D" as    baldly declared by STURP for the Linen of Turin?

Fig 17: See how an imprint of a 14cm plastic figurine responds to ImageJ software. 




Unique encoded 3D?



Final summary of posting: 

The Linen  (no, NOT Shroud!) of Turin, fabricated in the mid- 14th century as a bigger and better rival to the Veil of Veronica, was NOT intended to be seen as the final burial shroud.
(So let's forget about resurrection imaging on the Third Day etc).

 No, it was  created as a trompe d'oeil, intended to represent the kind of image that might have been left on Joseph of Arimathea's "fine linen", deployed in transport mode from cross to tomb.

 Why is the body image a tone-reversed image?

Answer: because it it was intended to be seen as a body IMPRINT, created in bodily sweat in the first instance, then yellowed by centuries of ageing.

(Explaining the blood is a little more problematical: it does not appear to solely blood, or as some might say "blood". Other ingredients appear to be present (red clay according to microscopist Lucotte and Paris-based colleagues).   Yes, they can be explained, including the "blood first,  image second" chronology deduced by Adler and Heller's experiments with blood-digesting enzyme.

 A possible scenario is as follows: an adult human male was first smeared lightly with vegetable oil from head to foot, then sprinkled lightly FROM ABOVE (while in recumbent, i.e.  lying down mode) with plain white flour. The excess of flour was then shaken off, then a slurry of red clay trickled on to represent blood "in all the right places" to identify the mode of death (crucifixion) and what preceded it (scourging, crown of thorns etc) thus identifying the individual's fate according to Holy Scripture. 
The imprinted linen was then roasted, maybe in a bread-making oven, maybe over the glowing embers of a charcoal fire  - responsible  incidentally for those otherwise mysterious "poker holes" - to develop the body image colour as Maillard browning products. The clay areas were then overlaid with blood (real blood, or something that resembled it closely).

The final step, post-roasting, pre-addition of  ';real' blood, was to wash vigorously with soap and water to remove thick surface encrustation, leaving just a faint, dare one say ghostly image of a man's naked crucified figure.

Scourge marks?  As with bloodstains from "nails",  "crown of thorns" etc, they too show no presence in the body image, i.e. are entirely blood (or "blood"). They could have been added at any time (one still awaits data on whether they too are underneath or, conversely,  on top of the body image).

Claims that the Linen could simply have been "painted" to create the body image overlook one crucial feature - namely the negative (tone-reversed) body image.  STURP itself gave priority to the oh-so- tiresome  "just a painting" claim, which was correctly rejected.

What was  less understandable was the omission of any reference in the '81 Summary to the negative image, or to Adler and Heller's hugely significant finding that the body image chromophore was bleachable by 3 different chemical reagents, known to act on colour-conferring conjugated double bonds, i.e. organic, NOT inorganic chromophores.

The bleaching discovery should (by rights) have consigned the red ochre (iron oxide) claim of Walter McCrone immediately to the dustbin of history (but for unfathomable reasons did not do so, his successors at the  Chicago McCrone Research Institute  robotically continuing to trumpet it 40 years later on their founder's website!).

Let's not beat about the bush: the Turin Linen is a fraud, albeit a very clever one.  Its creators tried to conjure up a "1st century" reproduction of Joseph of Arimathea's 'transport linen' that was as realistic as possible, one that looked as if it had been created 1300 years earlier, one  that looked as it it had naturally aged for the following 1300 years prior to its (unexplained) appearance at a tiny Champagne village, albeit with a monarch-funded private chapel attached to the property of one of his leading knights in the land (read: King's favourite!)

The Linen of Turin is by far and away the most successful forgery in entire human history.

Why? Because it wasn't content to "paint" a facsimile version of Joseph of Arimeathea's transport linen.

Oh no! It set out to reproduce the manner of its making in as realistic a manner as possible, namely by whole-body imprinting, followed by an artificial ageing procedure. In short, it was meticulous in its attention to detail.  In modern terminology it was 'nerdy' and thus 'detail-obsessed'  in the extreme.

 But then bored under-occupied clerics attached to Geoffroi de Charny's chapel,  apparently 6 of them no less (link),  employed merely to pray constantly for his warrior soul,  forever at risk of being detached from his body in knightly mortal combat alongside his King, had to find ways to occupy their time...

They certainly made their mark on history - both 20th and 21st century. They opened the door to endless pseudoscience, introducing a cautionary note to the manner in which  modern-day "science" can either be applied - or MISAPPLIED!

Any time you, dear reader, suspect that "science" is being misapplied, ask yourself the following question: is the proponent of this or that seemingly-unscientific proposition addressing IN DETAIL objections from sceptics and other critics?

Or is their "science" in fact pseudoscience, mere window-dressing  intended as part of a marketing exercise, inviting no comment, no objections?

A new and simple thermal imprinting model for the Turin Shroud needing only plain white flour and a hot iron - in 12 pictures.

1. Make a thin slurry of plain white flour with cold water.
2.Paint skin with slurry
3. Drape linen over coated skin
4. Gently pat linen to mould to contours.
5. Peel back linen. Flour imprint scarcely visible at this stage.
6. But most of the slurry transfers to the linen, being sticky.
7. Press with hot iron on opposite side from imprint (highest temperature setting) on part of the flour imprint. Leave one side cold as control.
8. Result - a faint image, reminiscent of the Turin Shroud.
9. Is the image wash-resistant? Detach a test portion (right)
10.The imprint withstood 15 minutes immersion in cold water
11. Would it withstand washing with soap?
12. Answer - yes, though a little fainter.

This is very simple technology, needless to say, requiring only plain flour and a hot flat iron (smoothing irons must surely have existed in the 14th century, when the Shroud of Turin was first put on public display (Lirey, France, circa 1357).

Regardless of authenticity, this simple demonstration is my answer to those investigators in Italy and elsewhere who claim that the image of Shroud of Turin can never be reproduced under laboratory conditions. It CAN be reproduced, at least as regards macroscopic aspects, in one's own home living room. Microscopic characteristics need further investigation.



Update: Sunday 21 June

Mechanism of enhanced browning in image zone? Presumably a non-enzymatic Maillard browning reaction between reducing sugars and proteins.

 reducing sugars + protein (or free amino acids etc)  ->  complex mix of yellow melanoidins

(The reducing sugars provide reactive carbonyl groups , the protein etc provides reactive amino groups)

But there are 3 combinations that will need to be considered  that are not mutually exclusive, i.e. two or more may be operating simultaneously:

 Reducing sugar (white flour) reacting at high temperature with protein/amino acids (linen fibres)
 Reducing sugar (white flour) reacting at high temperature with protein/amino acids (white flour)
 Reducing sugar (linen fibres) reacting at high temperature with protein/amino acids (white flour)

The fourth combination,  i.e. reducing sugar (linen fibres)/protein/amino acids (linen fibres), is not listed since that would account only for the slight "scorching" of background linen one sees outside the image areas, i.e. background coloration.


There is also the possibility that proteins are not involved, that the tan coloured image is the result of pyrolysis (aka caramelisation) reactions involving carbohydrates only. Expect to see a postscript here shortly (a few days at most) on the effect of replacing whole white flour with gluten-free starch. The latter will use starch granules isolated from white flour by water-washing and sedimentation, as described in an earlier post here in which nitric acid was used for  colour development of the primary imprint, dubbed the "stick 'n' stain" variant of the generic 2-stage imprinting/developing model.


Speaking of which, nitric acid that is, which was the first means of Stage 2 colour development to be reported on this site, its use is emblazoned on the banner of this blogger's specialist Shroud site., despite being a vicious corrosive reagent towards human flesh,.

Present banner (June 2015) on my shroudofturinwithoutallthehype.com site


 But which of the two chief variants of 2-stage imprinting (3 if one counts the promising results with hot limewater) would medieval forgers have been more likely to use:(a)  the use of a hot smoothing iron, as described here, or (b) exposure to nitric acid vapour or solution?

Is the hot iron (or maybe an oven roasting) more likely than treatment with a novelty chemical reagent that was probably little known in the 14th century outside of alchemists' secretive laboratories? Do I need to substitute a collage showing the steps in this posting for the one you see above, if only to flag up the variant that is more user-friendly, i.e. safer to deploy in one's own 21st century home should any readers be minded to check out the claims made here?

I shall make the collage, but may not replace the present one immediately. Better maybe to hold fire on whether the putative forger of the Turin Shroud was more physically or chemically minded. (He did not need to know the chemistry of Maillard reactions to make an educated guess that a hot iron would  scorch a flour imprint more readily than the linen on which it was deposited). (Afterthought: I could make a twin-collage, showing both the "iron" versus "non-iron" method. There's no need to make an instant decision as to which was more probable in the mid-14th century.)

But there again, our medieval forgers, even if alchemist- (aka proto-chemist)- assisted, did not need to know the molecular mechanism as to how nitric acid reacts with proteins to give a yellow colour (xanthoproteic reaction). All they needed to know was its reputation for staining skin yellow, and then have seized on that as a way of simulating an ancient  then 1300 year old whole body imprint (as sweat) by imprinting with ANY convenient organic substance - a proxy for sweat - and developing chemically with any reagent that might turn it a permanent non-fading yellow.

Here's a link to a site on the history of ironing. It's not entirely clear when the box iron, loaded with hot charcoal, first put in an appearance (one trusts they knew to keep the windows open, to avoid deadly carbon monoxide poisoning).

Box irons are still used to this day, e.g. in India:

Box iron with lid raised to show smoking hot charcoal

 Might there not have been a risk of getting red hot embers onto one's prize linen? Is anyone thinking what I'm thinking. Yes, those "L-shaped poker holes".

Were they incorporated right from the start  - when the TS image was created, using a box-iron to develop the colour? If so, then from the symmetry, the linen would have been folded in 4 - lengthwise then width-wise (see above link). It's not impossible that the linen would have been folded before 2nd stage thermal development. Indeed, that might provide an explanation for the divider-like faint longitudinal and transverse 'seams' one sees, somewhat paler than the rest of the body image or background regions.

Later thoughts:  prompted by the result of the wash tests with water then soap/water, one could hypothesize/rationalize as follows. When the imprint is heated with the iron, there are two distinct Maillard reactions - one with the flour "impurity layer" and one with the linen itself, each providing carbohydrate, protein or both. It's the browned coating with its Maillard/caramelized products that washes off with soap and water, but those associated with the linen fibres stay put. It is presumably the latter we see today in the faint, scarcely visible image. Originally, the image would have been more intense, due to the impurity derived carbohydrate and/or protein. For Charles Freeman to claim as he does that investigators have totally ignored image degradation over the centuries (to sustain his scientifically-bankrupt line that the TS is  'just a painting')  is not only wrong. It is insulting. Maybe if he took the time to read the scientific literature, instead of dismissing scientists as art history philistines, which they may or may not be (it being of little consequence and probably irrelevant where the enigmatic TS negative imprints is concerned) he would see that image degradation is something that always has to be factored into everyone's thinking, and indeed is and has been, whether formally acknowledged or not, at least where this investigator is concerned. The man is way, way out of his depth in attempting to brush aside decades of detailed scientific investigation that shows the TS image is UNIQUE, and cannot therefore be subsumed into art history, least of all when that requires the qualifying assumption (read fix) that the original artist's pigment have (conveniently) detached leaving no trace of their original presence, merely an unexplained negative image (which Freeman mistook at least initially to mean left-right reversed, as in a mirror image).  Forgive my saying Charles, but you're an incorrigible time waster.

 Update: 21 June

Have separated starch from gluten, and tested them singly and in combination with a hot iron. No obvious browning reactions were seen.  It might be soluble flour proteins that are needed for a Maillard reaction (gluten protein is highly insoluble, which explains why it's so easy to separate from starch granules, simply by washing out the latter from a stiff dough with water). Soluble reducing sugars of flour may also be needed, with intact starch not substituting, even at high temperature.While it's of interest scientifically to understand the chemistry, in particular to confirm or disprove the presumed Maillard reaction, ignorance of the precise chemistry does not detract from the hypothesis proposed, namely that the TS image was formed by a browning reaction in an extraneous organic material imprinted onto linen, probably flour glue (its adhesive properties making it an imprinting medium par excellence).

Update 22 June

Here's a headline that appeared in yesterday's Daily Mail (or Daily Wail as some prefer to call it!).


Note there was an estimable 127 comments when I did that screenshot a few minutes ago. Some of them are mine (as Colin Steven, the first two thirds of this blogger's full name). Began with a brief plug for the latest 'hot iron' model, it being simplicity itself, though the Mail does not as I recall permit links so I chose not to risk it. Got into a quite upmarket discussion (for the hard-bitten, don't-give-me-that-bullsh*t  regular clientele of the Mail that is) with one "Birchy of Blackburn" who says he knows this blogger from "Mr. Porter's site". Has he left comments there one wonders? Can't say as I recall input from the north of England.

Thank goodness those green up-vote arrows and red down-vote arrows of the Mail are not copied more extensively. They seem to bring out the worst in people. I much prefer systems like Disqus, where a down-vote simply reduces the tally of up-votes.

Speaking of which (Disqus) here's an opportunist comment placed just a minute ago on the Disqus-hosted Telegraph:


The Pope joins the EU in a sad world of make-believe

Title: "The Pope" ... "sad world of make believe".
Fiddlesticks. For one moment I thought that might be a reference to his paying homage to the Shroud of Turin, allowing one shamelessly to plug (without splitting an infinitive) the latest Blue Peter* "Make Your Own Turin Shroud" shamelessly immodest breakthrough discovery. (Link to this posting).

Simply paint a gluey cold water slurry of plain white flour onto one's 3D subject - whether a real person or a bas relief (probably the latter for the face), imprint onto linen, then press the dried imprint with a really hot iron (linen setting). Hey presto, one gets a negative sepia-coloured Shroud-like image of one's subject.Nope, it won't wash out, so may well be permanent. It may even display those 'mysterious' 3D properties if you use dowloadable software (ImageJ etc) that excels in finding "3D" wherever there's tonal contrast in one's 2D image.



Yup, strictly for home (UK) consumption, I call it the Blue Peter model, it being one you can try at home.

"Here's one we made earlier"


Next experiment: the face/head is the major problem as regards contact imprinting. Luigi Garlaschelli said as much, and considered that a bas relief was needed in place of a real face. But why? Most of the face is fairly flat relief, except for (a) the nose and (b) the eye hollows. That's provided one has made a decision NOT to imprint the sides of the face, so as to avoid lateral distortion. It is a simple matter to imprint off the highest relief, simply by patting the linen vertically downwards against 3D relief, never sideways.

Is it mainly the nose that is the problem? What kind of imprint might one obtain if an imprint were taken with linen that had a cut-out, allowing the nose to protrude/poke through? It's a purely theoretical exercise of course, designed to see if the nose is the major problem, and seeing what kind of contact image is obtainable if the nose is prevented from causing too much deformity in the linen.

It was quite difficult to see any 3D imaging of the nose using ImageJ in its Thermal LUT mode. That might be telling  us something (like the substitution of a more forger-friendly bas relief for a real face?)

I shall also try imprinting crossed hands as per Shroud.. There's a simple explanation for why the thumbs are missing.  Try crossing your own hands, dear reader, as per Shroud, in such a way as to lock them together, to prevent one sliding on the other.  Where's the best place to put the thumbs? The 'thumbless' hands may be prima facie evidence for imprinting off a LIVE cooperative subject who's been told to maintain a fixed immobile position  (as if deceased) while imprinting is in progress.

Update Tuesday June 23

Yes those are the next two mini-projects - modelling the crossed hands and "noseless " face, in that order.


The image on the left are the crossed hands one sees with Shroud Scope (Durante, 2002 with added contrast). At first sight it looks as if the subject's right hand is crossed over his left, partly obscuring the latter. But it's an imprint which creates a mirror image (left-right reversed). The image on the right shows how the subject would have looked had one seen him with one's own eyes and/or taken a photograph. So that is the configuration that I (or my partner) will have to adopt prior to pasting with flour glue, draping with linen and then imprinting: left hand will be placed over right. The thumb of the left hand will be slipped out of sight behind the wrist of the right hand, serving as an anti-slide lock (see earlier) so will escape being imaged. Likewise the thumb of the right hand -  which will simply be kept out of sight by hiding behind the fingers of the same hand. Yes, those "missing thumbs" are easily accounted for in a contact imprinting model. Why might a forger not want thumbs "in the picture"? Easy. Look at one's own hand. The thumb is not in the same plane as the fingers, being rotated at almost 90 degrees out of plane.  It also occupies a lower horizontal plane than the fingers unless the hand is pressed flat  against a hard surface. Any attempt to imprint the thumbs risks producing a result that looks a bit "wrong" as an imprint, even if anatomically correct. Solution: tuck the thumbs out of sight, so they don't get imprinted. Summary: left hand will be crossed over right, then the two coated with flour paste. Linen will be draped over and patted gently, with no attempt to imprint right into the junction of the two hands, thereby achieving that gap in the image where the linen has bridged the step between higher and lower levels. I may even place a small  adhesive pad  at the approximate site one would expect a nail to be used if through the palm rather than wrist to see where it appears as a dimple on the imprinted image.

Afterthought: one does not wait for one's partner to be free if one imprints in "LUWU" instead of normal "LOTTO" presentation. LUWU (Linen Underneath With Underlay) is where the linen is draped over something soft, like several thicknesses of bath towel, and the "subject" pressed into it from above. That can be done solo to get a quickie result. What's more it's more likely to have gaps in the image due to bridging across steps in level, because there's no means of manually moulding linen to contours unless in LOTTO mode (Linen On Top, Then Overlay).
 Preliminary result: will appear here shortly.


Flour imprint of my own crossed hands, LUWU mode, before and after photo-enhancement.


The image on the left is the as-is imprint ( no photediting) that stubbornly remained after (a) thorough rinsing and kneading with cold water (b) vigorous brushing of surface with a tiff-bristle toothbrush (c) application of soap and water. In other words, the image, while very faint (as per Turin Shroud!) is one that might still be there in years, decades, mainly longer. The image on the right is the same, after applying my favourite settings in Microsoft Office Picture Manager (mainly an increase in contrast, with minor adjustment to brightness and midtone setting). Note the missing region (as per Shroud!) where the linen has bridged the height-difference between upper and lower hand.

Negative aspects: there is excessive lateral distortion, an effect no doubt of employing the LUWU imprinting mode with too soft and underlay, causing too much contact between linen and the sides of the wrist etc. That can be easily remedied by switching to LOTTO mode (tomorrow), using manual moulding. My wife has agreed to be the subject, but that will require hands folded in the opposite configuration (right over left) to avoid contact between flour paste and rings!.

Update: Have been accused of trolling for the first of 5 comments placed on a Christopher Booker thread in the Telegraph (currently 6737 comments in total!).

Judge for yourselves dear reader whether this blogger is a troll. Here are ALL my comments to that thread in chronological order. That's not counting the hundreds I used to send to the Telegraph some 2-4 years ago on the topic of climate change when it was a main interest.

Methinks there's a certain blogmeister in South Carolina, USA who needs to lighten up. He also needs to stop using that obsessional single-issue site of his to snipe and make wholly unjustified character attacks.

Seems there's been an awful lot of going up - right from the time when CO2 records began, without a single break in the upward trend. Guess we'll just have to be patient and wait for it suddenly to start zig-zagging, and then collapse back again, as you seem to be optimistically forecasting. Ah, those confident forecasts. Seems they exist on both sides of the argument.
















ColinB to SuffolkBoy a day ago 
 

You surely don't think there could have been that amount of fluctuation in the 19th century CO2 levels, i.e. in different parts of the globe, in different years, so as to make the average the same or even higher than today's?
If the state-of-the-art measurements we get today show consistent values centred around 0.039% (? adjusted for geographical location, seasonal effects etc, proximity to volcanoes etc) that are consistently nudging upwards year-on-year then some might think it's scarcely possibly that levels were yo-yoying wildly as your cited chart suggests when Trollope or Dickens were writing their novels, and went on doing so right through to the sudden stabilizing effect of 'Love Me Do' and the Merseybeat.

















ColinB to SuffolkBoy a day ago 
 

Thanks for the clarification. I checked your link. It's a snapshot of course, with a relatively narrow time window - 6 weeks- with most of the extra CO2 coming from south of the equator. Reasons? Maybe biodegrading of old roots and foliage before new growth and/or rainy seasons get underway. Am not sure. But the pattern on that chart is a result, needless to say, of unequal heating of the Earth's surface and the seasonal effects due to the Earth's axis being tilted relative to its plane of rotation about the Sun. Those same effects create climate but also weather of course, i.e. cyclonic updraughts in the tropics, anti cyclonic down-draughts in the more temperate regions, all helping to even out and eventually equalizing the localized excess or deficit of CO2 relative to the global mean. Moral: beware snapshots, even those on 6 weeks long exposure if discussing weather and/or climate. Best to focus on annual averages, where the CO2 chart is a smooth consistently upwards curve, not the sawtooth one we see in plots of month-by-month values.

AGW or not? Here we have a supra-scientific, quasi-theological conundrum, one that is setting one Homo interneticus at the throat of another. But there are far more important issues (well, immediate ones) that need our attention, like external threats to our polity and way of life. Sorry, grandchildren, you'll have to wait your turn in the queue.
We need the equivalent of the First Council of Nicea urgently to thrash out the issues, to adjudicate, and then rule on what's a heresy (or at any rate, a sterile tail-chasing exercise that helps no one) and what's orthodoxy.
Or there again, we could compromise (old English pastime). Let's watch closely what happens to the ice in the Arctic and Antarctic. If there's progressive melting, regardless of what happens to air or sea temperature, then we can conclude the planet is warming dangerously, and take no chances with those GHGs . Get those solar panels installed and quick.
If on the other hand the ice cover were to remain the same, give or take a few good years and bad years, then let's discuss other more important issues affecting our security and welfare, like, say, the current visa-free mass migration via overloaded vessel from Africa into Europe, the progressive sovietization of the eurozone, the imminent incorporation of Greece into the Russian sphere of influence...

Today, I've put up another 7 or so comments on an entirely different topic, but not a single plug anywhere to my new Shroud model. That trolling must have been a passing phase...

Middle-lane hogging is a dangerous act of wilful stupidity


Further update: 21:10  June 23

This comment has just appeared on the shroudstory site from Thibault Heimburger MD.


in response to Dan:

From Colin in “the Telegraph”: “Simply paint a gluey cold water slurry of plain white flour onto one’s 3D subject – whether a real person or a bas relief (probably the latter for the face), imprint onto linen, then press the dried imprint with a really hot iron (linen setting). Hey presto, one gets a negative sepia-coloured Shroud-like image of one’s subject. Nope, it won’t wash out, so may well be permanent. It may even display those ‘mysterious’ 3D properties if you use downloadable software (ImageJ etc) that excels in finding “3D” wherever there’s tonal contrast in one’s 2D image.”

Colin seems to be a very strange person.
Here and on his own blog he looks like a true scientist.
Now, in “the Telegraph” (!!), we have the very simple final answer.
No Colin, your results have nothing to do with the TS image properties.
Is Colin serious or not ?

Yes, Colin is serious, even when he writes to the Telegraph. TH may not be aware, that this blogger has a long association with the Telegraph. It was at a Telegraph/E.on -sponsored BrainsTrust ("Talking Energy") that he got to meet and talk to Sir David King, UK's Chief Scientific Adviser and other influential policy makers on various matters to do with Green initiatives. I'll see if I can find some links (from 5 or 6 years ago).  Yup, here's something unearthed from from the sciencebod archives.


Daily Telegraph Jan 2, 2010


Close-up. lower right. That's your host, who was invited to pen 10 weekly blogs for the main newspaper, and then invited to put the first question to the expert panel.



l.
And yes, Colin is deadly serious about the new simple two-stage imprinting process. It may not have used white flour (which incidentally was available to the well-off in medieval times, being simple to make in principle by sieving stone-ground wholemeal flour) and it may not have used a hot iron, or nitric acid or limewater for Stage 2 colour development. But I do maintain with a high degree of certainty that the image was produced by a two stage imprinting/colour development that resulted in the image appearing to be intrinsic to the linen fibres themselves, whether that is or is not the case. In fact, the fibres from the latest experiment above could serve as a handy model system for investigating that very question, with a view to applying them to the Shroud itself.  So far, I've avoided speculation as to what remains after the washing procedures described - whether it's still modified flour components, modified linen fibres, or a mixture of both.  Researching the TS image has to be a slow and methodical trial-and-error process, given we have no clues whatsoever as to the processes that took place to produce that image. The STURP findings tell us next to nothing about the chemical make-up of the image layer. Thibault Heimburger, sad to say, is not part of the solution. He is part of the problem, being relentlessly negative and non-constructive in his never-ending stream of dismissive observations.

Update: Wed 24 June

Have posted this to the article by Michael Fabricant, MP for Lichfield: entitled "The EU referendunm is a race against time"






"Just a few days ago, an Ipsos MORI poll – if you believe any poll since May 7 – reported that 66 per cent would vote to stay in the EU and only 22 per cent would vote to leave."

Where on earth did the writer get that figure? At the DT's recently updated poll (see link to the Ipsos Mori chart) the gap has narrowed to 55% IN and 45% OUT. What's more the two plot lines are converging!

PS The same chart is at the end of the article. Hover one's pointer over the latest portion to get the actual figures I quoted.

Further postscript (IMPORTANT!): there's something not quite right about the DT's chart. If one moves the pointer slightly, one finds there are TWO snapshot polls given for June 2015, with a big difference between the two. Michael Fabricant MP (who penned this article) has quoted the earlier of the two values, which are those put out recently by the pollsters themselves.
https://www.ipsos-mori.com/res...

Either there's been a mistake in plotting out the IpsosMori data, OR, opinion is shifting rapidly towards OUT, and IM knows that, explaining why there are now two quite different results for June 2015. OK, so opinion polls can be misleading, as shown by the GE results, but there's no need to make them any more misleading than they already are by quoting out-of-date results when things are in a state of rapid flux.

Further update (last on this posting): with help from my wife, yesterday's experiment has been done, but in LOTTO mode(so far at Stage 1 imprint only) I decided finally to use my hands  as the "subject", having tutored my assistant in correct patting technique, use of my camera etc, in the course of which a sudden thought occurred to me which should have come sooner: the way to avoid lateral distortion in this technique is to apply paste only to those parts one wants to be imaged. That way, it doesn't matter if one's assistant is overzealous, gets pat-happy, straying round those forbidden sides! Result,assuming the result is not a total disaster, will be reported on the next posting.

Successful result - a good set of photographs. Draft title for next posting:



Man on the Turin Shroud:  the mystery may finally be solved - at least in principle.
