Comment promoted: what are we to make of the second face on the reverse side of the Turin Shroud?

Site banner: see how a simulated sweat imprint (my wet hand pressed down onto dark fabric) responds magnificently to 3D-rendering computer software (ImageJ) before and after tone-reversal (negative back to positive image). Remind you of anything? Like those supposedly “unique”  and “encoded” 3D-properties of the Shroud of Turin body image? For a more realistic aged/yellowed sweat imprint, see the many postings on this site since 2014 obtained with the aid of my Model 10 (imprinting off  parts, notably head and hands, of a real body (mine!) onto linen with white wheaten flour, followed by heat-development of the image to generate carbon-based and thus bleachable straw-coloured melanoidins via Maillard reactions between wheat proteins and reducing sugars). 


This comment was supplied by Matt a couple of days ago:

Good day Colin, I’ve been reading your blog and you’ve revealed things to me I never knew about the shroud given all the hype that’s out there. Just wanted your opinion on something. What do you make of the “second face” on the reverse side claim. I’ve heard even some pro-shroud people deny it. Do you have a post about it? Thanks.

From the Independent, April, 2004:

Independent April 2004 second face on Turin Shroud


Here’s my immediate (stalling!) reply:

Hello Matt.

No, I’ve never addressed the claim for partial  obverse reverse-side  images as yet, notably face and hands, feeling as I do that I needed to be better informed as to the nature of the topside image first. When I say images, I mean ones that can or cannot be seen with photographs alone, rather than those problematical computer-aided reconstructions reported by Giulio Fanti and his team.

Mario Latendresse put a couple of photos up on his site a while ago. I’ve taken the face, shown first “as is” and then after photoenhancement in my unsophisticated MS Office Picture Manager, using just the 5 controls in brightness and contrast.



Durante-verso-face duplicate -45,100,-50,30,-100


What do you reckon Matt? Is there an image on the opposite side of the linen or not? Mario says there’s not…

(There’s probably no point our discussing THAT claimed image unless agreed on whether there really is one or not!).

PS: Beware: the photoedited one has also been left/right reversed, unlike the ‘as is’. Apols for that (it was done for future use, when comparing with topside image).

Matt came back with this:

Well if there is no image, where is the hair coming from unless the front image isn’t as superficial as they’re saying?  It’s hard for me to believe a lot of the pro-shroudies given the spurious nature of a lot of their claims. I saw your comment on Dan Porter’s site about the graphite background and the picture of the red painting on linen. Could this be a light phenomena? assuming the images are as superficial as they say. In any case, I’m convinced that the shroud is a fake. I think the image of the hair may come from the outlines of the painted blood and perhaps some oil substance staining through which adds to the paredolia.

In the big picture I think this is the last thing Christianity has seeing that they’ve lost when it comes to creationism, geocentrism and Adam and Eve. Seeing that all these things have been debunked. I think the shroud will follow.

What say you?


I replied with this (having to postpone for now comment on the “graphite and red painting” which has slipped my memory):

Yes, the pro-authenticity folk in general (Mario L a notable exception – see his site) seem to be relaxed about an image that is on both faces of the Shroud, albeit exceedingly faint on the obverse side, yet say there’s nothing in between! That takes quite a bit of explaining, wouldn’t you say, and I don’t recall seeing any attempts as yet to come up with a cogent explanation?

I have one, and it’s tentative, so am pleased to see your thinking is at least partly along the same lines.

Yup, we’re talking about OIL.

My flour imprinting works best when there’s vegetable oil present, not just to attach flour to the skin initially, but to help colour development in the oven too.

The oil helps to ‘micro-fry’ the particles of flour, which then proceed to turn brown due to Maillard reactions.  A small surplus of oil then acts as a liquid vehicle, allowing that cocktail of yellow/brown Maillard products to penetrate the weave of the linen. The likely route for capillary migration is the narrow channels BETWEEN the fibres, as can be easily modelled with ink ( I did a clip for YouTube back in 2015 , enter “dynamic penetration of ink” into your search engine), so the brown cocktail can get from one side of the linen to the other INSIDE the threads, out of sight, and then, if there’s sufficient, proceed to stain the opposite face where they emerge.

So why an image (of sorts) on the opposite face, rather than a mere oil stain?

Maybe the Maillard cocktail deposits solid polymeric highly-pigmented melanoidins on its short journey. The latter attach strongly to the fibres, so that the migrating oil gets cleaner and cleaner, finally scarcely visible in the cloth, leaving the pigmented image on the obverse side roughly the same shape and size as the topside, but not exactly the same (which might explain Fanti’s curious finding that the main and subsidiary image were not quite identical in his computer-assisted imaging).

Thanks for the interest Matt. Let me know if you have any further insights. Right or wrong they are all grist to the mill.


Thanks for the appreciative reply,  Matt, and for giving this  Shroud investigator an opportunity to finally grasp – after 5 long years – that particular nettle as regards the reverse-side face!   Feel free to call in again – anytime. Informed comment is especially welcome.

If I have any afterthoughts on that reverse-side face, I’ll tack them on the end here in the coming days or weeks.

Comments invited. ( Warning:  the site’s WordPress host requires me to vet a contributor’s first-time comment before it can appear. Thereafter they are displayed immediately).

Rapid but short-lived transport of Maillard products also accounts for the peculiar  characteristics of image threads  and their fibres as seen under a low power microscope (see Mark Evans photomicrographs).


Yup, I refer to (a) the so-called half-tone effect and (b) abrupt discontinuities in fibre coloration.

The half-tone effect (an unhelpful – and probably over-simplistic term in my view) is shorthand for saying there are – or may be – only two kinds of image fibres  – coloured (full tone) and uncoloured (no tone) – with no in-betweens.  (Think of it as akin to the use of binary numbering  (o, 1 only ) in digitized imaging).  Discontinuites refers to the presence of cut-offs in coloration  along certain fibres for no obvious reasons.

Both these effects are explicable if it’s assumed that there’s a limited supply of hot, briefly-liquified  Maillard reaction products from the heated flour imprint that migrate rapidly for a short distance only along and between the fibres of linen threads. That results in even-staining of some but not all fibres (half-tone effect) with abrupt cut-offs in coloration (discontinuities) when the supply of liquid from the superficial thermal zone is exhausted.

Update : 17:00 hours, UK time, March 20

Here I am,  some 36 hours after posting, and STILL the major search engine has failed to spot this latest posting.

Had I posted it on my sciencebuzz site (Google -hosted) it would have appeared almost instantly!

Oops. Mustn’t  be seen to have a down on the internet Google giant, must I?

Nope. Microsoft’s Bing site  also fails to show it in its first 20 listings under a (shroud of turin ) search. (But then  Microsoft’s Bing has NEVER listed this site – to the best of my knowledge.

There’s something distinctly rotten (or at any rate, PC-obsessed) in the Stateside search engines  –  Google, Bing etc, something  we Brits and Europeans have to be content with, no local alternatives being available.

Musn’t offend your Stateside  Catholics, must we, Google, Bing etc?

PC-obsessed , ideas-stifling Stateside PC rules OK?  (Or should that be  multi-billion $ e-commerce income ?).

Update: Tuesday 21st March, 2017

07:30: Have just used the Feedback facility on Bing to send the following message:

Here’s a link to my specialist Shroud of Turin site.

It has been running for more than 5 years, has well over 400 postings, advances new models and theories, yet continues to show up NOWHERE in your listings under a (shroud of turin) search. It’s currently listed on Page 5* of returns.

Why are you effectively censoring me, preventing my original research and ideas from reaching Bing searchers? Is it because my views are anti-authenticity? Is it because you are keen to spare the feelings of those whose religion predisposes them to favouring authenticity? Since when has it been the job of a search engine to protect anyone from the real world?


s of t page 5 google- old post still listed 48 hrs after posting second face



Yahoo?  I’ve just searched the first 20 pages of Yahoo under (shroud of turin). No listing for this site, confirming previous experience over the years. Why not?  Who knows?

What I do know is that there was no mechanism for sending the same message to Yahoo as the one I sent Bing earlier this morning.  (There was a word limit – unannounced upfront!). What I did find was a page that invited me to “submit” my site as if Yahoo were doing me a favour  (nope, it’s web site creators who are doing YOU a favour, Yahoo) but that would require “registration”.

So I went back to the Suggestions tab, ignoring all the copious blurb about what they want and don’t want, and sent this short sweet message:





Update, Tuesday 15:00

Hey ho. Google has finally spotted this latest posting, which (for all its faults) says a lot more for Google than it does for the deeply-suspect Bing or Yahoo.

google page 4 listing of new post 21 march pm s of t search


Thank you Google. You came through for me (at last!).

Update: Thursday March 23

But there’s a downside to the world’s favourite search engine where this site is concerned, but it needs a sharp eye to spot it.

Search for (turin shroud) on Stateside (enter if outside mainland USA, “ncr” specifying “no country redirect) and here’s what you will  currently see – or something very similar:

google dot com turin shroud see page 5 my site 23 march 17


Yup, that’s this site, shown 3 entries down on Page 5 of returns.

So what would you expect to see if you had entered (shroud of turin), which I suspect a majority of folk will do, with or without the unnecessary “of”.  You would expect to get a similar or identical result, yes?

Well, you don’t. You will get the same result as the one I discovered and announced many months ago. You will find NO RETURNS FOR THIS SITE, at least on the first two dozen pages or so, even assuming the search engine allows you to access so many pages.

Yup, this site is invisible Stateside to anyone searching (shroud of turin) Stateside – which according to this site’s flag counter is where most of the interest in the Shroud resides –  way , way above my own largely Shroud-indifferent country (UK)

I’ve sent one final, despairing email to the search engine, using its Feedback facility, attaching my name and email address, asking it to correct this anomaly forthwith. If there’s no reply by the end of the day, I’ll reproduce the email here, and then think about acting on my threat to devote a full posting to the iniquity of being deprived of clicks, readers and  page-ranking by the perverse nature of what I’ve described above.

At least I get a listing of sorts, which is more than one can say for  Bing and Yahoo (see earlier), those two blights on the blogosphere who continue year after year to display their hugely suspect  -and I assume partisan – blind spot for this site. (Yahoo I’ve discovered currently lists 5 or 6  different postings from  a rival pro-authenticity  Australia-based Shroud blog scattered throughout the first 20 pages of returns  – which basically says all one needs to know about its impartiality and professionalism).

It’s now 2100 hours on Thursday March 23.  I’ve jusr rechecked the page rankings on Stateside No change. If one searches under (turin shroud) this site appears on Page 5. If one searches under (shroud of turin) my sciencebuzz site appears on Page 18, but this site appears NOWHERE. That’s despite logging a complaint many months ago. Nothing’s been done. Is it any wonder this site has near zero impact in the USA, since most folk there probably make “shroud” the first word in their search.

Here’s a copy of the communication that Google received from me first thing this morning UK time via its feedback facility:

Hello Google

Yet again, I see my UK-based site listed on Stateside under (turin shroud) but curiously and perhaps significantly NOT under (shroud of turin).

This is at best bizarre, but it’s also deeply worrying, indeed suspicious, since you are depriving me of searchers and readers, which then means I don’t get the Stateside ranking that I believe my site deserves after hundreds of postings over 5 years.

I’ve made this same complaint to you before, via this Feedback facility and online, but nothing has been done.

I’ll wait 24 hours, and if I’m still not listed on under (shroud of turin) then I’ll make a separate posting of this strange anomaly on the part of your allegedly algorithm-driven search engine. I shall be flagging up my strong suspicion of ‘dirty tricks’ by those who attempt to influence Google listings and rankings – Stateside especially – under (shroud of turin) but who have carelessly it seems overlooked the alternative (turin shroud) – arguably a smoking gun.

Please deal with it NOW, not next week or next year!

Colin Berry, UK


Update: Friday March 24

Have discovered that this, my latest posting,  DOES appear on a Stateside search under (shroud of turin) but not under the default “Any Time”. One has to specify “Past week” or “Past month”, accessed via the Tools tab (which I suspect few general users ever deploy).

So the crawler and algorithm are picking up the existence of this site, and displaying it briefly, albeit to the cognoscenti wanting to know what’s new, but filtering it off from the main “Any Time” shop window.

Well, I’ve long suspected that Google goes in for window-dressing , correction, BIG correction, window-EXCLUSION, on entry-level searches, giving the lie to any suggestion that page rankings are determined purely by an algorithm  (at least an algorithm that is responsive to objective criteria only, making no value pre-judgments as to likely ‘mass  appeal,  special-interest appeal’, outside interest  credit-card flashing appeal  etc.).

Google etc claim to be search engines, not mere e-commerce trade directories, so should perform as such, and indeed should be made to do so,  via regulatory agencies, at least when ranking sites beyond their own shores, regardless of where those rankings are displayed!

In short, this site, MY site,  is being partially-discriminated against, failing to appear when a Stateside  searcher enters (shroud of turin) into his or her default-setting My own countrymen and women in the UK face no such filter. Big deal!

I accuse you Google of cyber-colonialism. You are wilfully  preventing my site from receiving Stateside attention and visitors  which I believe it warrants after 5 years and hundreds of postings. Indeed, I would be saying the same if my site were brand new! The Shroud of Turin is of international interest, whether seen from a religious or scientific perspective. No one should be denied the right to know what is being thought and said  online by folk in other countries that contributes to the worldwide debate.

As others have been saying in recent days in regard to other more serious matters to do with your modus operandi,  Google, notably your placing  UK taxpayer-funded ads onto anti-Semitic, neo-Nazi YouTube videos, it’s time you cleaned up your act, across the board.

I repeat: it’s time you cleaned up your act, Google, across the board. (As for Bing and Yahoo, words fail me).


Monday 27th March 2017

See this link to a BBC scrutiny of the mighty Google, and the way it has come not only to dominate search, but what folk are allowed to see and not see:

Just google it: How one company came to dominate search

Here’s a choice passage that says it all:

Trying to figure out how to please Google’s algorithm is rather like trying to appease an omnipotent, capricious and ultimately unknowable god.

You may say as long as Google’s top results are useful to searchers, it’s tough luck on those who rank lower – and if those results stop being useful, then some other pair of students at Stanford will spot the gap in the market and dream up a better way. Right?

Maybe – or maybe not. Search was a competitive business in the late 1990s. But now, it may be a natural monopoly – in other words, an industry that is extremely hard for a second entrant to succeed in.

The reason? Among the best ways to improve the usefulness of search results is to analyse which links were ultimately clicked by people who previously performed the same search, as well as what the user has searched for before.

Google has far more of that data than anyone else. That suggests the company may continue to shape our access to knowledge for generations to come.

Professor Brian Cox thinks carefully before saying: “It is important for people in my position – by which I mean scientists that have some sort of public voice – to say that not all opinions are equal.” The 49-year-old physicist, TV presenter and all-round cheerleader for rational thought has seen long-held facts under fire of late. Last week, basketball supremo Shaquille O’Neill expressed his view that the Earth is flat;  Donald Trump’s former rival, now colleague, Ben Carson says he doesn’t believe in the Big Bang. ..

Update: Tuesday March 28

Still on my anti- (so-called) search engine rant, I got to wondering if it was just Stateside that was preventing entry-level (shroud of turin) searchers from accessing this site.

Answer: NO!  The same applies to searchers on Canada’s and Australia’s That’s on the default “anytime” setting (I may be visible on past week, past month etc  which few will use).

I then had  a sudden thought (when using Why have I never seen Mario Latendresse’s splendid  site with its invaluable Shroud Scope when searching on or even, at least not in the first dozen or even 20 pages? Has Mario been given the same blackball treatment as this investigator, despite being pro-authenticity (indeed, a founder member of the Shroud Science Group)?

Answer: YES!. Search (shroud of turin) on his own country’s, and he’s not listed anywhere on the first 20 pages!

I was right not to entertain dark conspiracies about sindonology (aka shroudology) being at the root of this exclusion from All Time Google listings. If that were the case, Mario would be getting special treatment. He’s not! There now seems little doubt that it’s Google deciding what entry-level searchers under (shroud of turin) should be allowed go see, and not see. In short, Google is not acting as a search engine pure and simple. It’s either manually ‘curating’ what comes from its allegedly algorithm-driven crawler OR has cleverly programmed the algorithm to reject sites that fail certain Google-ordained criteria.  And what might those criteria be, one wonders?  Might they be an aversion to facts, to ongoing research, to (dare one say) SCHOLARSHIP, the latter having no part  to play in its e-commerce promoting business model, one that delivers billions of $$$$$$  each year via pay-per-click?

Yup, I suspect that to be the answer. Google (and its minor competitors like Bing and Yahoo) are all in the business of dumbing-down internet search, killing the true spirit of enquiry.

You are a disgrace to Western civilization, Google et al, founded as it is on a respect for free speech, for new thinking …

Something has to be done about these ethically-blinkered, greed-obsessed control-freak Californians, and soon!!!

This site is presently listed at the bottom of Page 5 listings under a (shroud of turin)  search on That’s despite several hundred postings over the last 5 years. many highlighted on other sites, notably  Dan Porter ‘s up till Dec 2015 and elsewhere, and many links to other sites (which Google says are crucial).

Yet when one looks at the top of current Page 5 listings, here’s the kind of site that Google decides to give precedence:

Shroud of Turin — Watchtower ONLINE LIBRARY

This is an authorized Web site of Jehovah’s Witnesses. It is a research tool for publications in various languages produced by Jehovah’s Witnesses.

Yes. a one-off posting by the Jehovah’s Witnesses, with no long-term interest in the Shroud, or indeed any obvious reason to be interested, is allowed to push a specialist long-term interest site such as this down to the bottom of Page 5. Indeed, many such one-off ‘passing interest’ sites have been allowed to do this, thanks to the deplorable Google algorithm (with or without human intervention) making this and other more informed, on-the-ball sites scarcely visible.

This site was set up 5 years ago with the aim of reporting online, in real time, the progress of an investigation into the how and why the Turin Shroud could have been fabricated in such a way as to fool modern-day scientists (or “scientists”) into thinking it was authentic 1st century provenance, allegedly and mistakenly a genuine image of the crucified Jesus.

Thanks to Google and other California-based so-called search “engines” I now realize that the internet was not the hoped-for  means of delivering new research, new thinking, new ideas, new theories into the public domain. The page rankings are a cesspit of  accumulated human-deposited crap.

Yup, these last 5 years have been a complete and utter waste of this investigator’s time, thanks to his  trust and reliance on search engines to transmit findings under a simple straightforward (shroud of turin) internet search.


Goodbye sordid, disreputable Google et al.  I regard you as enemies of human enlightenment and progress, indeed of Western civilization.  You will henceforth be treated here with the contempt you richly deserve – and ignored completely.

If I do another posting, it will be negative in its take on all things sindonological, given the array of vested interests that refuse to LISTEN to opposing opinions.

Probable title for next posting: “Turin Shroud: so how come STURP managed to get it so COMPLETELY wrong?” 

It’s half-written already.

  1. Colin Berry says:

    Hiya jman

    Yup, I’ve seen it, and to say I was truly appalled at the gross liberties taken with the use of physical techniques to probe forensic microchemistry and biology would be a massive understatement. I inserted this brief statement into my July 1 posting (the one preceding yesterday’s “infrared” posting):

    Saturday July 8th

    See (or better still, don’t) this latest Fanti et al bit of fantisy masquerading as analytical chemistry:

    LInk to: Atomic resolution studies detect new biologic evidences on the Turin Shroud

    Sindonological pseudoscience does not get much worse than this. Which referees on Plos One allowed this paper through? Name them!


    Nuff said methinks…

    Thanks for your interest (and visit).

  2. jman98 says:

    Hi Colin are you aware of a recent scientific article released around June 30th showing new research on samples obtained from the shroud? It was revealed that blood was found from these samples and they reveal chemical coumpounds that are released into the blood stream during a traumatic injury on the body. Im skeptical of course as too how prevelant these chemical conpounds really are in the blood stream. Also if real human blood is found how would that play into the hoax or creation of the shroud? Did the creator cut his own hand lol! Seems as though you are greatly educated on the subject and the only skeptic who is consistently doing research into the subject. Thanks for your great work I plan to continue to read through it and learn more about this subject. Heres the original research paper: Just wanted to know your thoughts, thanks!

  3. Colin Berry says:

    Hello again Matt

    Are you still around (I’d understand if you weren’t, you being as you’ve said a busy fellow with a wide range of interests)?

    I think I’m now able to explain the ‘second face’ in a way that is backed up with experimental data. See my current posting dated July 1 : “My Model 10 – thermal imprinting with white flour onto linen – can account for the curious properties of the Turin Shroud body image”

    Previously I thought it was a mechanism operating entirely from the imprinted side, relying on capillary transport in the narrow channels between the closely packed linen fibres within each linen thread. I’ve now had to revise that view.

    I now think there’s something going on INSIDE each linen fibre, maybe involving even narrower capillary channels between cellulose microfibrils within linen fibres (maybe not) and that effects of oven heat on the most superficial hottest parts of the reverse side of the linen are activating that mechanism so as to produce the second reverse-face image. See my latest photomicrograph copied/pasted from the end to the start of the posting. In short, the ‘second face’ effect depends on simultaneous heat BOTH sides of the linen: a preponderance of heat reaching the reverse side of the linen favours a more intense reverse-side image as can be shown experimentally using different geometries inside the oven as regards position of linen relative to source of oven heat.

    These are early days experimentally – there is much more to be done. For now, let me leave you and other site visitors with this thought: if the reverse side image on the newly-created Shroud was anything like my model system, then it comprised highly superficial coloured fibres mixed in with many uncoloured ones, giving an overall impression of faint straw colour. But those coloured fibres were fragile and brittle, and over the centuries many will have snapped off as a result of handling and fallen away, leaving the merest hint of reverse side colour that we see today! For all we know, the early owners of the Shroud did not care for the reverse side image, and may have hastened its disappearance with gentle brushing, snapping off those brittle reverse-side fibres!

    That reverse side image, or rather modelling thereof, is providing a valuable and unexpected research tool – but I’m not expecting ‘sindonology’ to display the slightest interest, whether at Pasco next week or thereafter. Sindonology has no time – and indeed nothing but contempt – for any thinking that does not presuppose a 1st century provenance and authenticity. On that basis alone, sindonology is for the most part PSEUDOSCIENCE…

    Google has dropped this site from its ‘any time’ listings for a (shroud of turin) search where it used to appear anywhere between pages 3 and 7. I wonder why…

    The pen used to be considered mightier than the sword. But the online keyboard is sadly not mightier than the world’s favourite search engine, not while the latter pursues its own mysterious self-interested agenda, no doubt influenced by outside pressures ..

    Today’s headline in the London Times, July 13, 2017:

    Google pays academics millions for key support
    Researchers get secret funds

    Google has paid millions of dollars to academics at British and American universities for research that it hoped would sway public opinion and influence policy in favour of the tech giant. A watchdog identified 329 pieces of research funded directly or indirectly by Google since 2005 in key…

  4. Matt says:

    Btw, whats the vertical line that looks like a fold running down the length of the Shroud on the one side. I looked at shroud scope and it looked like its part of the original cloth, is that a fold or something? Someone was trying to prove to me along time ago that that was the (already debunked) “invisible reweaving area”. Could you fill me in on that?

    • Colin Berry says:

      It’s the so-called side strip, approx 6 inches wide Matt. The weave is continuous with the main body of the Shroud, with some suggesting there’s been no separation – the seam being a tuck to create piping, others that for reason or reasons unknown, the edge was cut completely off then reattached to preserve the original alignment.

      Nobody can call themselves a real sindonologist until they have racked their brains on the side strip, then produced a pdf full of ifs and buts leaving the reader none the wiser. I’ve yet to cross that particular bridge.

  5. Colin Berry says:

    Thanks again Matt. I’ll start with your 5, order still to be decided, probably posting the first on Saturday pm am (UK time). First I have to compose a preamble, making clear how and why things have gone seriously off-beam in sindonology.

    The rot began to set in with the 1981 STURP summary*, the background to which can be found towards the end of John Heller’s 1983 book on his involvement with the STURP project. Wild and inaccurate ‘acid-fixated’ chemical speculation involving atmospheric oxygen, essentially mimicking the natural ageing of linen cellulose, was promoted in the STURP Summary as if established fact, discouraging more promising lines of experimental modelling, notably those involving THERMOchemical as distinct from mere chemical ones.Then the propaganda started against anything that could be tagged as a “scorch hypothesis”, with the ludicrous claim that “all scorches fluoresce under uv”. It’s time that someone started to set the record straight. I guess that someone will have to be me.

    * See this passage in particular:

    “The scientific concensus (sic) 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.”

  6. Colin Berry says:

    Thanks Matt. Any thoughts on which to tackle first (first 5 or so)?

    • Matt says:

      I was interested in 8 and 23 (I would call it a failure, instead of ill judged) the whole vanillin “dating” has every flaw that creationists level against radiometric dating and I’m willing to bet a lot of these shroudies are creationists (maybe not all). 19 and 2 especially 2 because its a laughable argument like looking at a whale and calling it a monkey. There IS “blood” on the hair. 29 as well. In summary 8, 23, 19, 2 and 20 where the ones that stuck out the most.

  7. Colin Berry says:

    Hello again Matt. Are you still looking in? If so, here’s a progress report. I’ve listed some 27 points – see below – re STURP’s performance (plus later authenticity-promoting ‘sindonologists’) that I consider represent a hugely irritating and frustrating non-enlightenment as regards the nature of the Turin Shroud. Let’s not mince our words: most could have been avoided by more careful selection and screening of personnel, more objective, less bedazzled by things such as so-called “encoded 3D properties” (just one of many instances of galloping pseudoscience)).

    My next posting, to be started at the weekend, will take each of those 27 points from the outline skeleton and develop them more fully. It will take days, probably weeks, to do justice to them all, but I’ve decided to make it a single posting. To keep length to a tolerable minimum there will be a few images only (I may decide to set up a separate image archive elsewhere, having 2 other semi-dormant websites to choose from).

    Here we are: 27 points (maybe more to come!):

    1. Dispensing with the cylindrical, wrap-around distortion objection to imprinting via direct contact.
    2. Addressing the claim that blood not really on the hair, used in Trojan horse strategy to claim image and blood are out of stereoregister, then used to implicate radiation as imaging mechanism
    3. Failure to recognize that ‘neck crease’ is no ordinary crease, failure to appreciate the clue it provides to imprinting mechanism that utilizes direct contact and applied pressure.
    4. Failure to consider the evidence for thermal imprinting mechanism, indeed contemptuous dismissal thereof. Failure to do experiments with model scorch imprinting (3d, bas relief etc).
    5. Failure of STURP to recognize that blood stains are too good to be true. Coroner Robert Bucklin’s inability to recognize that blood stains cannot necessarily be equated with wounds.
    6. Failure to recognize that a subset of bloodstains – the scourge marks – are also too good to be true, with near-perfect imprinting of the metal bead tips of one or more Roman flagra.
    7. The radiocarbon dating: why the opposition to repeat testing (St.Louis conference, 2014) coming from STURP team leader and other big shot attendees at Discussion forum no less.
    8. The ‘just a painting’ nonsense from someone with no scientific credentials -and scarcely any significant ones as a historian either. Shame on ‘History Today’ for allowing that shallow, ill-informed nonsense into the public domain.
    9. STURP’s failure to prioritize, to go to Turin with one or more positive models.
    10. STURP’s failure to ensure proper sampling methods for blood and body image. Rogers’ fait accompli re “Mylar sticky tape” and the severe practical problems it posed for himself and others, notably those charged with blood testing.
    11. STURP’s failure to properly characterize the presence of authentic human porphyrin, despite late recruiting of porphyrin specialist Alan Adler. Adler’s self re-invention as a physiology/medicine expert re blood clotting, liver metabolism etc. Ouch,
    12. The premature embrace of radiation models, ones that go beyond any known science (like auto-emission of electromagnetic or nuclear radiation from a corpse).
    13. The cursory attempt to dismiss any kind of imprinting by direct-contact, based on self-serving models.
    14. Failure to grasp the implications of the negative image.
    15. Gross overhyping of so-called ‘encoded 3D properties’. Failure to experiment with model imprints that would distinguish between 3D properties and 3D response in computer software programmed to read and re-map image density as height on an imaginary z axis with virtual shadowing as an optional 3D-enhancing extra.
    16. Failure to recognize that the TS was seen by early viewers as a body IMPRINT left on J of A’s linen by SWEAT and blood, and could thus have been designed as such in the 14th century.
    17. Failure by STURP and later sindonologists to recognize that the biblical account does not permit one to assume that the linen, whether authentic or not, was used and intended as a BURIAL shroud, when its purpose was probably for improvised ‘stretcher’ ‘/bodybag’ transport between cross and tomb.
    18. Overhyping of alleged image superficiality, the justification for resort to radiation, lasers etc. Failure to place microscopic transverse sections of threads or even single fibres into the public domain, assuming (optimistically) they were ever part of the experimental protocol.
    19. Attempts to use uv fluorescence or lack thereof – with no experimental data – as a means of dismissing the ‘scorch hypothesis’ (some scorches? all scorches? all thermal imprinting mechanisms?) . Meaning of “scorch”?
    20. Certain of the more over-hyped aspects of the “blood stain” story, like why the blood looks too red to be authentic blood (“extraordinary levels of bilirubin”) , the ‘blood-before-image’ mantra etc etc. Unrealistic scenarios re behaviour of detached blood clots etc.
    21. Heller and Adler’s failure to recognize the real significance of their important diimide bleaching finding. Its use to inflict an over-dogmatic identification of the image chromophore as “conjugated carbonyl” with an untested oxidation model, failing to recognize that double bond formation is achievable by chemical dehydration of sugars alone, not needing oxidation. Inappropriate unrealistic model for chemical dehydration (conc. H2SO4) that sidelined thermal dehydration. Assumption that cellulose is the only target for fibre coloration, ignoring other endogenous or exogenous compounds.
    22. Rogers’ alternative Maillard hypothesis. Pros and cons. Inappropriate deployment of 60 degrees C in his model system, having claimed his Maillard chemistry would work at rock cave temperatures. Failure to make clear how starch can serve as source for “reducing sugar”; questionable substitution of dextrins (semi-hydrolysed starch) for starch in model system. How quietly tweaked self-serving models risk undermining research credentials.
    23. Ill-judged attempts to substitute chemical for radiocarbon clocks by Rogers (vanillin) and Fanti (spectral changes, mechanical strength testing) all of which are invalidated if image formation required an oven-heating stage (accelerated ageing).
    24. To be announced later.
    25. Rogers’ inadequately documented claim for blood hydroxyproline as a marker for Shroud having not been exposed to heat. Likely confusion between blood and connective tissue collagen etc., between free and protein-incorporated hydroxyproline.
    26. Rogers’ claim for crystalline supposedly ‘native ordered’ cellulose as a marker for Shroud linen not having been exposed to heat. Failure to recognize phenomenon of retrogradation (i.e recrystallization after ‘melting’) as pointed out by Adrie van der Hoeven.
    27. The controversial involvement of microscopist Walter McCrone, with claims that the body image could be entirely accounted for as paint pigment, notably red ochre (iron oxide). Failure of STURP to shoot that down at the earliest opportunity with the diimide finding, allowing the mistaken notion to take root, surviving to the present day as the risible attention-seeking pseudo-scientific, pseudo-historical ‘just a painting’ dross.

    The Shroud image is said to be super-superficial, yet I have still to see any quantitative measurements to justify the alleged 200nm thickness. Do they exist, or are we being conned with still more fanciful, self-serving pseudoscience (“too superficial to be man-made”)?

    The obvious way to measure image thickness would be to look at a cross-section of an image fibre under the microscope, maybe with added contrast, to make the faint yellow coloration appear as dark brown. That’s a cross- section note, since one can learn next to nothing about image thickness from a longitudinal section, e.g STURP’s Mark Evans photomicrographs.

    I have yet to see sindonology display an image fibre cross-section. Why not?

    That’s one more black mark to STURP and its so-called ‘documenting photographers’. Microscopic cross-sections play a hugely important role in science.

    If anyone knows of an image fibre cross-section, please supply a link.

    PS (added Tue April 4). I should have said “cross section of entire thread“, it being important to know if there’s coloration in the tiny channels between the fibres, initially narrow air-filled cavities, as my flour-imprinting, thermal-cocktail-exuding Model 10 would predict.

    Any time you feel like doing a guest posting, Matt, you have only to say, given we’re both on the same wavelength. It would give me a few more days in which to continue sketching out my next posting where I finally sit in judgement on the whole of STURP and subsequent sindonology (a thankless unedifying task, believe me, given the almost totally non-joined up thinking).

    One or maybe two thousand words, more or less if you prefer, to

    Please say YES!

      I’d love to, but my time is limited, I’m a busy guy. Not only that I’m still learning the science (or lack thereof) behind the Shroud. Needless to say you are definitely more equipped to post about the subject. I do write on my spare time about a load of topics, mainly refuting young-earth creationism and miracle claims from the Catholic Church. I haven’t posted any of it on any forum since my writings are just for me to organize my thoughts. There’s a lot of b.s out there for sure and many instances of these religious zealots lying through their teeth to stir the fears and the “feelies” of the faithful. However, I will keep your offer in mind if I write anything that would possibly be of value for this blog.

      But I’m not kidding, would the people who own the Shroud allow you to take samples if you asked?

      Also, I just viewed your post “Modeling the Shroud of Turin with White Flour, Olive oil and a real face” and saw the pictures of the hands

      I was amazed by the detail and shroud like images (I was surprised Thibault was impressed too). However, my question is, were these images as superficial as the actual shroud image and/or your experiments on the “To all those who persist in claiming the Shroud image is far too superficial…”

      Thanks for the feedback, and I will keep your offer in mind.

  10. Matt says:

    They’re all pseudoscientists, in every sense of the word. And they want to keep it a mystery and exaggerate their claims and pretend the radiocarbon date was wrong and pretend there’s blood on it, and pretend it’s a photographic negative, and pretend some more.. It seems they want to keep it a mystery and get the feelies and keep the circus going. Btw, you’re a scientist, have you ever thought about getting your hands on the Shroud of Turin and do your own examinations? Or do they only allow believers.

  11. Colin Berry says:

    Thanks Matt.

    That posting is in preparation as we speak. It’s taking longer than expected. Why? Well, it means having to re-examine some of the claims of folk who have passed on and thus no longer around to defend themselves. That either strains my highly undeveloped diplomatic skills to breaking point, and/or risks blunting the intended message. One shall endeavour to err on the side of hitting where it hurts (the living) or no longer hurts (the dead)! There’s been too much kid glove treatment if you ask me, an essential component of keeping negative comment in the family and/or sanctifying dear departed relatives, and thus keeping the authenticity-promoting, playing-to-the-gallery show/circus on the road to continue its journey unhindered by the likes of we callow sceptics. (One has only to look at the provisional self-serving programme for July’s grandly titled “International Conference” in Pasco, Washington State to see what I mean. How do you like your image-forming and/or radiocarbon date-skewing body-emitting neutrons served up – by nuclear engineer Bob Rucker or lawyer-turned-celebrity-author Mark Antonacci, neither of whom responds to my emails) .

    Provisional plan is to post a skeleton version, hopefully by the end of the week, and then flesh it out in additional bite-size instalments – in other words to become by degrees a gradual living, breathing thing – one that makes best use of the informal open-to-all, feel-free-to-criticize blogging format chosen to report this still-ongoing raspberry-blowing project in real time.

    Hey, thanks for dedicating a post to my comment. I didn’t know it was worth that much. Looking forward to reading,“Turin Shroud: so how come STURP managed to get it so COMPLETELY wrong?”.
