Oil paint on glass, produced by David Beauchamp in roughly forty-five minutes while watching stand-up comedy. This painting was the most successful and was used to produce three different images on linen.

More on the Shadow technique of recreating the Shroud of Turin PING!

This is the website where the N. D. Wilson explains how it was done... more pictures, including 3D renderings.

Interesting. I didn't realize that medieval people had windowpane style glass available.

[1john2 3and4]

Man! I'd avoid that comedian next time.

[BushCountry]

The images produced by the Beauchamp painting did not match the finesse of the original, but aptly demonstrated the viability of the technique.

I really get sick and tired of sites like these. There have been hundreds of explanations of how the shroud was created, yet no one, I repeat, no one can duplicate the Shroud exactly. With thousands of years of technological advancements in science, I will not be happy until someone can precisely duplicate the Shroud exactly, using technology from the correct time period. I do not want to hear that it is possible until it can be proved.

Window panes were made by spinning a blob of molten glass on a rod.
I watched a Williamsburg reenacter do it on a TV show once and he said up until very recent times, it was not possible to get more than about a 2 foot circle of "window pane".
Out of that circular more-or-less flat piece of glass, small square or rectangular panes were cut.
That why medieval and ancient windows had so many panes of glass of in them.
It wasn't for "looks"; it was simply because bigger panes of glass weren't possible yet.
My house is almost 300 years old and there are still original panes left in most of the windows.
You can see pontil marks and "bull's eyes" where the glassblower cut it off of the rod.
The glass in the old windows is all "wavy" to some extent and the thickness of each pane varies wildly, even within itself.

I can't imagine where they found a man-sized sheet of glass back then.

A great book on the subject is called "The Resurrection of the Shroud".
I got mine on Barnes & Noble's website, dirt cheap and brand new.
They may still have some copies left.

They wouldn't need a man-sized piece of glass. They'd only need to place several end to end.

Using the sun is a simple process which I've done many times to safely bleach out antique fabric. A solution of salt or lemon juice accelerates the process so the 10 period isn't needed.

Saw the website. The man's irreverence is egregious. ("Watching stand-up comedy," "pirate image.") Swordmaker, what are your thoughts on the length discrepancy of the front and back images? He mentioned it on his faq page, I don't believe I've ever seen it discussed here. (Could be wrong about that!)

[Alamo-Girl]

Thanks for the ping!

This technique is apparently such a bleaching process... however, bleaching from light exposure does not stop. Wilson shadowed certain portions of his linen and exposed the rest through the glass... remove the glass and the rest of the linen should "catch-up" and bleach out as well. The shroud image is now at least 700 years old and shows no signs of having the image bleach out.

Nah. Not gonna touch this one.

Have you ever heard of the 1875 locust plague in the US? Interesting story. In todays dollars, it was a $162 billion loss. The locust here went extinct and no-one is sure why.

That's the part the article explains.

The differences go away when you map the body onto the draped cloth. Experiments conducted by researchers who placed human volunteers on shroud like cloths, mapped the contiguous points of their bodies vertically collimated and found similar length differences.

Prof. ssa Emanuela Marinelli- Co-authored with Alessandro Cagnazzo and Prof. Giulio Fanti a study on this very subject: Computerized Anthropometric Analysis of the Man of the Turin Shroud . This is a PDF file and you will need Acrobat Reader to read it.

I assure you that forensic anthropologists have examined the image on the shrouud and are convinced it is of an actual human body.

They wouldn't need a man-sized piece of glass. They'd only need to place several end to end.

Wouldn't the place where the pieces met leave some kind of imprint on the pattern?

Or would the waves or lumps in the glass?

This seems like something to check.

[Swordmaker]

That's the part the article explains.

But the hypothetical artist would have to understand what he was atempting to paint on glass... adjusting his paint opacity inversely to distance from shroud surface and using the glass's transparency in place of dark paint shadow. This is NOT an intuitive thing to do. Wilson's artist knew what he was attempting to accomplish.

The "photograph" that Wilson produced with his technique is exactly that: a photo-graph - a picture written with light. The image on the shroud shows NO light artifacting... shadows, etc. Its artificiality is very apparent in the mesa like appearance of the 3D effect because the gradient of the paint opacity is artificial.

I am willing to bet that Wilson's sun-bleached photographs will disappear quite rapidly with time and exposure to light because the unbleached linen that comprises his image will bleach out.

To "duplicate" the shroud's image, the proposed example has to meet many criteria to be deemed successful... Wilson's contender meets only two of about 20 requirements.

[Swordmaker]

Wouldn't the place where the pieces met leave some kind of imprint on the pattern? Or would the waves or lumps in the glass? This seems like something to check.

Checking is unnecessary... the Shroud's image has been published and examined minutely... no artifacting of overlapping or butted together glass panes has been observed.

[Salamander]

Not to mention that 21st century man, with all the existing technology available, just *now* came up with this "technique"?
We're supposed to believe, paradoxically, that medieval artists already knew this?
Was it something the alchemists stumbled upon whilst trying to turn lead into gold?

I think they're really stretching for a means to discredit it.

FWIW, personally, I used to be one of the shroud's shrillest, cruelest critics.

[and just to further muddle the hypothetical mix, I'm an artist trained in multiple media and have also spent thousands of hours in the darkroom, playing around with a wide range of "special effects" photography starting with primitive pinhole cameras and ending with Photo-shopping existing images.]

Even perfectly cut and squared pieces of glass would exhibit refraction where the pieces butted together, thereby altering the light rays of the illumination source.
I would guess that the refractions would somehow, if only subtly, leave their distinctive marks on the finished image.
If a camera lens or darkroom enlarger has the slightest scratch or imperfection, that scratch or imperfection will result in imperfect light transmission and -will- show on both the negative and positive.
Let them duplicate their results with panes of glass of a size and quality that would have been available in -that- time period.
