I noticed that you have responded to my criticism of your posting, The Shroud of Turin: 2.6. The other marks (5): Coins over eyes, with an inline addendum. You begin:

Response to Dan Porter In a post, "The Forger and the Coins: One in a Gazillion with 13 Zeroes," Dan Porter, owner of the Shroud of Turin Blog, has criticised my post above, dismissing the evidence for the coins over the eyes of the man on the Shroud as "pure pareidolia":

"… But this is so only if you believe that the images of coins are there. I’ve spent years considering this question; I don’t believe they’re there. What people see, I think, is pure pareidolia.

But pareidolia is (my emphasis):

"…a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant … Common examples include seeing images of animals or faces in clouds …"[126]

"… the imagined perception of a pattern or meaning where it does not actually exist, as in considering the moon to have human features"[127].

Stephen, if you don’t like the term pareidolia – and I still do – then how about visual noise?

You continue:

However, in this Porter is simply ignoring the evidence above, for example, that Jackson, et al. found on their VP-8 Image Analyzer three-dimensional `relief map’ of the Shroud, images of two, round, flat objects over the eyes, which were the same size and shape of Pontius Pilate leptons.

Round flat objects? Let’s look at several images:

image1) This is perhaps the most famous of the images. It is a VP8 image prepared by Jackson. One might say the images over the eyes seem like flat disks. There might be something there. It’s hard to tell. Barrie Schwortz says,

I do not argue that there appears to be something on the eyes of the man of the Shroud, and it may well be coins or potshards . . .

But, I’m not even sure of that.

clip_image0012) In the photo Stephen, you provide, seemingly (I agree with you on this) sourced from Giovanni Tamburelli of the Centro Studie Laboratori Telecomunicazioni S.p.A., Turin, Italy, we see, as you put it, “small, round, raised, object over each eye.” These certainly don’t appear like, “two, round, flat objects.” These could very well simply be eyelids.

You continue:

They did not "imagine" them-the images really are there. And this was confirmed by others using different three-dimensional computer processing. Even if the details on the face of those two objects could not be seen, it would still be a reasonable conclusion that they are Pontius Pilate leptons.

Look! How can this possibly be a reasonable conclusion? Potshards? Um, maybe. Nothing but the normal curvature of eyes, perhaps swollen eyes? It seems so.

3) The History Channel provides an image prepared by Ray Downing during the making of the Real Face of Jesus. I think this provides good confirmation that “two, round, flat objects” ARE NOT clearly (conclusively) there.

If anything, the 3D images, and there are others as well, argue against the presence of coins over the eyes.

But Stephen, you continue:

And Porter is simply ignoring the improbability that a lituus shape and even one letter, in the correct order and angle of rotation around the lituus (both of which can be clearly seen on the Shroud – see above) `just happen’ to be chance patterns in the Shroud weave, which `just happen’ to be over the eye of the man on the Shroud, is of the order of 1 in 1.1216 x 1015. Not to mention that the `chance patterns’ are three-dimensional, round and flat!

If I thought that what constituted particular shapes and letters was completely or mostly the same chemical product that constitutes the image of the man on the shroud, I might think the statistical argument has merit. But I don’t think so.

imageThe statistic that you refer to were based on observations made on the 1931 Giuseppe Enrie photographs, beautiful and detailed, technically wonderful and absolutely wrong for this kind of analysis of small details. Why? Because the film was high resolution orthochromatic film. The problem was compounded when Enrie coupled this film choice with near-raking light thus creating countless miniscule patterns and shapes from the shadows between threads of the weave. Since orthochromatic film basically only records black or white, any mid-tone grays that existed on the cloth as image, background banding patterns in the ancient the linen, and accumulations of centuries’ worth of dirt particles caused more miniscule imaging.

The picture on the right is an approximation of banding found in the face area. The dark horizontal band about a quarter of the way down goes right through the eyes. Vertical banding lines also go through both eyes. Before you can do any statistics you must adjust for the banding noise, shadow noise and visible contamination noise.

It helps to quote from something Barrie Schwortz wrote in 2009:

. . . the high resolution orthochromatic film used by Enrie, coupled with the extreme raking light he used when making the photographs, created an infinite number of patterns and shapes everywhere on the Shroud. Since orthochromatic film basically only records black or white, any mid-tone grays of the Shroud image were inherently altered or changed to only black or only white, in essence discarding much data and CHANGING the rest.

The grain structure of orthochromatic film itself is distinctive: It is not homogenous and consists of clumps and clusters of grain of different sizes that appear as an infinite myriad of shapes when magnified. It is easy to find anything you are looking for if you magnify and further duplicate the image onto additional generations of orthochromatic film, thus creating even more of these shapes.

Although Enrie’s images are superb for general views of the Shroud (they look great), they contain only a small part of the data that is actually on the Shroud so they are much less reliable for imaging research purposes and have a tendency to lead to "I think I see…" statements. I would feel much more confident if these claims were based on the full color images of the Shroud which contain ALL the data available.

As I used to try and explain to Fr. Francis Filas, who first "discovered" the rather dubious coin inscriptions over the eyes and who had enlarged and duplicated the Enrie images (through at least five generations – and always onto orthochromatic film), there is a fine line between enhancement and manipulation. Fr. Filas first presented his findings to the STURP team in 1979 and frankly, not one of the STURP imaging scientists accepted his claims.

And now Stephen, you suggest something that just isn’t true.

From other things Porter has written, for example, his preferring a naturalistic explanation of the Shroud’s image, I assume that he does not want there to be images of coins over the Shroud man’s eyes because that would be more problems for a naturalistic explanation of the Shroud’s image, and further evidence for a supernaturalistic explanation of it.

No. No. I don’t “prefer” a naturalistic explanation. I only prefer a true explanation. Less than a month ago I posted So which hypothesis, of all those ever proposed, do I prefer? in which I wrote:

I consider any image caused by radiation, of any kind, naturalistic. The only question is where the very natural radiation came from. I remain totally unconvinced from any evidence or by any argument so far presented that miracles produce energetic byproducts.

So which hypothesis, of all those ever proposed, do I prefer? None!

Let me repeat what I said: None!

Actually, I have a gut feeling that the image is miraculous in ways none of us have yet imagined (supernatural if you prefer that term). How is not something I am ready or able to articulate. I doubt the image was caused by the resurrection or by any energetic byproduct of the resurrection just as much as I doubt it is the accidental product of a pre/non-resurrection chemical reaction. 

Stephen, you conclude:

Therefore Porter blithely dismisses all the evidence above that there are Pontius Pilate coins over the eyes of the man on the Shroud with the `magic’ word "pareidolia"! But in so doing he goes far beyond what the word "pareidolia" means. However, Porter is welcome to his beliefs and I don’t see my role as convincing him, or anyone, but just presenting the evidence and letting my readers make up their own minds.

Blithely? You mean, lacking due thought or consideration? Talk about going beyond the meaning of a word.

I know there are still a few people who think there are images of coins over the eyes. That’s unfortunate.
