<snippage>Re #2: For one thing, the alleged 14th century artist claiming responsibility for the Shroud allegedly claimed it was a painting. If the Shroud wasn't painted, we can pretty much discard this alleged person's alleged claim (and, there are more reasons for being highly suspicious of his claim, anyway), and a little bit of evidence for the dating being correct can be tossed.
More of the same self-serving nonsense. You have failed to show that:
- the shroud image couldn't have been painted
- the shroud image wasn't painted on
- that there is any blood residue on the shroud
Yet despite this, you feel able to dismiss the inconvenient evidence of the reproducibility of the shroud and of the contemporary investigation of it's origin.
I note that despite using your usual weasel words ("there are more reasons for being highly suspicious of his claim, anyway") you fail to show your alleged evidence. Again.
For another thing, Walter McCrone -- the one hand's-on scientist (other than those involved in the carbon dating) claiming the Shroud to be a fake -- claimed that there was no blood on the Shroud, and that the Shroud was painted. Consequently, we can probably toss his testimony -- about the date of the Shroud -- as well.
For what I believe is the eleventh time,
you have shown no evidence of blood residue on the shroud. Yet despite this you dismiss the expert, detailed and lengthy analysis by McCrone. While you and your fellow shroudies have nothing to show that their is blood trace.

Hell, even most of STURP don't believe there is blood on the cloth. That's despite the outright lies that group has come out with.........
Otherwise, I'll need to introduce some more premises in order to complete my logical picture. Hopefully, I'll be able to lay out my extended syllogism, and start providing more (for some reason, the other members of this forum would replace "more" with "some") evidence for my different premises before I get distracted.
How about you stop wasting time on puerile methodological and proceedural nonsense and get on with showing the evidence you've been claiming to have for so long?
Now, I'm going to repeat myself as Jabba ignored me the last time I posted these inconvenient facts.
Here is a
summary of McCrone's examination; there are more details in his book
Judgement Day for the Turin Shroud (well worth reading; detailed and thorough). In brief: artist's pigments were found on the cloth, blood residue was not. Page 166 of that book covers the mistakes of Schwalbe, Roger, Heller and Adler in detail showing why their claims of blood are (to use McCrone's words) "incomprehensible nonsense". Specifically the Becke line test for refractive index.
His (peer reviewed) article '
The Shroud of Turin: Blood or Artist's Pigment?' (note: large PDF), was published in Accounts of Chemical Research in 1990.
He also published four other peer-reviewed papers on his examinations of the shroud in various journals; they are uniformly dismissive of it's authenticity. That's more than the shroudies have managed, even using their dubious tactics.
McCrone also carried out one of the first attempts to recreate the shroud using techniques of ~1350. Which Jabba repeatedly denies ever happened.
“By spectroscopic and chemical tests (conversion of heme to a porphyrin), we have identified the presence of blood in the alleged blood areas of the Shroud of Turin.” (John Heller and Alan Adler, 1980, p. 2742)
Reality: Untrue. Even Heller and Adler accept that their test in this paper was inconclusive, since all they did was prove the presence of a porphyrin, of which there are many in nature, including plants. In a second paper, they were deceived by false positive reactions to the presence of iron and protein in the alleged blood pigment and binder. Walter McCrone’s specific tests for blood were all negative, as were the tests of earlier unbiased Italian investigators. All these facts have been repeatedly pointed out to shroudies and are usually ignored or handwaved.
"The blood stains are composed of hemoglobin and also give a positive test for serum albumin.” (STURP Summary)
Reality. Not even remotely true. There is no hemoglobin, serum albumin, or blood of any kind on the Shroud. The supposed blood is composed mainly of vermilion and red ochre pigments. The proteins and albumin detected by STURP are from boiled parchment and possibly egg used as binder in the tempera pigment.
"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." (STURP Summary)
Reality: The Shroud was either painted or, more likely, was once in direct contact with a bas-relief sculpture, carving, or cast. The image is too undistorted to be the result of any natural means of image transfer from a human body. The "blood" was artistically applied after the image was laid down on the linen cloth.
"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. 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." (STURP Summary)
Reality: Blatant lies. Even before the STURP report was published McCrone and others had duplicated it. Skeptics have demonstrated that the Shroud could easily have been created by an artist using materials and techniques available in early fourteenth century France several times since then.
Summary:
Perhaps a change of colour will help?
All competent, properly-conducted microanalytical tests for blood or hemoglobin on the Shroud have been negative.
No amount of handwaving on the part of Jabba or the other shroudies changes this.
[Again many thanks to Steven Schafersman for his excellent work in collecting and collating information on the shroud.]
