1. "Researchers, in large numbers, now believe that in the 16th century, a corner of the Shroud had been expertly repaired using a mending technique known as “invisible reweaving.” It was from this repaired corner that the carbon 14 samples were taken. This resulted in a mixed sample of both new and old fibers leading to erroneous carbon 14 dating in 1988." ↩ ↩

2. "In 2002, Turin undertook a secret restoration of the Shroud. Archeologists, scientists, and scholars of all sorts were horrified when they learned of it after the fact. It was reckless. Bill Meacham called it disastrous. It cannot be undone. Some scientists suggest that the restoration may have created problems that could potentially damage the cloth sometime in the future." ↩

1. "The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.  The strip came from a single site on the main body of the shroud away from any patches or charred areas." ↩

In contrast to the blood area, there is no evidence of cementation between fibers or capillary flow of liquids in image fibers." ↩ ↩

Evaristo writes:  "According to the testimony of King Umberto II of Savoy (later recalled by friends, the exiled Monarch entertained in the 1950s, at Villa Italia, in Cascais, Portugal), oral tradition in the Savoy Royal Family confirmed that the Custodians of the Holy Shroud, from the earliest medieval period, had sporadically made copies of the Shroud, but also removed fragments from all around the outermost edges of the Burial Cloth, even as far inward as 10 centimeters and distributed these to close relatives, devotees and allies.  That a mysterious seam or pronounced crease mark is visible all along one length of the Shroud is a fact that has baffled Scientists, some of whom have gone as far as to ridiculously (?) propose that a removed section was used to bind the Shroud to the Body at the chin, hands and feet and then sewn back onto the sheet, at a later date.  What could also be probable is that this thick, long strip of the original cloth was removed at one point [and] cut up into sections for distribution in reliquaries.  Another possible scenario is that this strip was used in a transfer boiling ritual or else separated, thread by thread, so as to have been incorporated into Ex Extractum copies of the Holy Shroud.  Any one of these processes could have been carried out by the Canons guarding the Shroud at Lirey or Chambery without the consent or knowledge of whoever owned the Sacred Relic.  Once carried out or the abuse discovered, the section could have ordered or rewoven, back onto the original whole or else the section in question was substituted with another piece of similar cloth.  According to King Umberto II, the pious practice of sharing Major Relics of the Holy Shroud was, according to tradition, continued by the first three Savoy Lords who possessed it, although they, unlike some of their predecessor Guardians, never purposely removed fragments from their areas with the image of the Corpus Sancti (Holy Body.)  Another fact confirmed by His Majesty was that it was traditionally affirmed, that at one point in the past, the edges of the Lenzuoli (Sheet) had become so tattered as to cause embarrassment or criticism of the Custodians, and those areas were repaired and rewoven using identical techniques, but obviously with similar, yet newer, materials containing dyes and other medieval manufacturing ingredients, in an attempt to better blend the new sections in, as best possible, with the original fabric.  In truth, the presence of medieval dyes was detected in these areas and this fact has been already pointed out by Scientists as additional proof of the inaccuracy of the 1988 Carbon 14 dating test results that placed the samples taken from these areas, as having been fabricated sometime in the middle ages.  In truth, any one of the aforementioned practices alone would also account, for not only the contamination of the fabric resulting in inaccurate Carbon 14 dating results, but also, the different types of linen, dyes, resins and fabric patches, discovered to have been present on the outermost edges of the sheet that usually held by Bishops during the exposition of the Sacred Relic to the public for veneration."
From pages 265-267:  "The removal of all patches and of the reinforcement Holland Cloth backing of the Holy Shroud, in the year 2002, confirmed what King Umberto had stated, namely that small sections of the repaired and rewoven edges, had continually been removed from the Sacred Relic and probably as late as the second half of the 17th century. That the practice of removing small fragments and even full length or width threads from the outer edges [of] the Holy Shroud, was a family tradition only finally suppressed by Duke Vittorio Amedeo II of Savoy, was another fact Umberto II of Savoy confirmed to Blue Army Founder and Shroud Devotee John Mathias Haffert, in the mid 1960’s.  It was the same Vittorio Amedeo II, who along with his wife, the Infanta Anna d’Orleans, personally assisted Blessed Sebastiano Valfre on June 6th, 1694, in repairing the Sacred Burial Cloth of the The Christ, shortly before transferring the Sacred Relic to the new Chapel of the Guarini. Later, it became a tradition on June 6th of each year for the Savoy Royal Family to distribute relics of the backing cloth.  It was in 1694, that in accordance to the Savoy Family tradition, some of the removed sections of thread were then woven into full size replicas of the Sindone (Shroud) for private or public veneration in Convents and Cathedrals during popular Holy Week celebrations.  Unlike the meticulous repair work that had been carried out in previous centuries by religious expert weavers following the damage caused to the Shroud by fires and which left little trace of the removed sections, the intervention of the Savoy and the Blessed was aimed primarily at replacing the cloth backing of the Relic giving it added thickness and strength and also a better contrast to the image.  The last intervention by religious sisters had been considered poor by the various members of the House of Savoy since, rather than reweaving the areas nearest the outermost edges that were either missing or had frayed from manipulation and wear, they had camouflaged them with cloth coverings and patches.  The backing of black cloth added by Blessed Sebastiano Valfre was later removed by Princess Maria Clotilde di Savoia, (1843-1911) Consort of Prince Napoleon, who substituted it for a pink silk on April 28th, 1868, on account of the backing having also become deteriorated from manipulation and removal of pieces for relics." ↩ ↩ ↩ ↩ ↩

1. "[Gilbert] Raes was clearly dealing with a seam and its sewing thread and with fabrics of different quality particulars on either side. If, however, one examines large photographs of the Shroud, the place where Raes' sample was taken can be seen between the main area of the Shroud and a rectangular patch. (This is close to the lower right foot of the frontal image.) This patch is below the ‘edging strip’ and appears in photographs as different in tone and hue to the main area. There is therefore some doubt as to whether the sample described by Professor Raes as ‘Piece II’ is the edging strip or part of a patch. It is important that this matter be resolved if it is intended that the forthcoming carbon dating tests are to be made on Raes' sample. The patch is probably mediaeval." ↩ ↩ ↩

1. "For the Shroud, there is a 600-year history in a number of different environments and unknown handling situations, and a possible further 1300-year existence during which the object could have been in contact with virtually any natural or man-made substance in the areas it was held. To measure Shroud samples, one must therefore consider every possible type of contamination and attempt to identify and counter them all, before the measurement is made and a "radiocarbon age" assigned. Clearly, this result can only be considered as a possibility, at best a good probability, but hedged by many uncertainties. It would not be an absolute calendar date, and it would not "prove" the Shroud to be authentic or a forgery." ↩ ↩

2. "Finally, the original sample was taken [by Gilbert Raes in 1973] at the junction of the side strip (believed by some scholars to be a later addition) and the (selvage?) border (possibly treated to prevent unraveling, and certainly more subject to contamination than the main body of the cloth). It could not be considered as a typical or representative sample of the relic." ↩ ↩ ↩

3. "[T]he choice of sampling sites on the relic should be governed by considerations of possible contamination and by the desirability of measuring both typical and atypical samples... My own tentative proposal for dating the Shroud is that at least five samples be taken: 1) a single thread from the middle of the cloth, between dorsal and ventral images; 2) a small piece cut just in from the edge next to the site of Raes' piece I; 3) a piece of the charred cloth; 4) a piece cut from the side strip next to the site of Raes'; 5) a piece of the backing cloth sewn on in 1534... Selvage edges would be avoided."  A selvage is an edge produced on fabric to prevent it from unraveling. ↩

4. "Like charcoal, the open cellulose structure of linen, especially aged linen, is highly porous, with large surface areas, and is particularly absorbent of organic substances in solution 'which can subsequently only be dislodged with difficulty... possible contamination always represents an element of uncertainty which no amount of laboratory pretreatment or measurement can totally efface.'" ↩

5. "No responsible field archaeologist would trust a single date, or a series of dates on a single feature, to settle a major historical issue, establish a site or cultural chronology, etc. No responsible radiocarbon scientist would claim that it was proven that all contaminants had been removed and that the dating range produced for a sample was without doubt its actual calendar age. The public and many non-specialist academics do seem to share the misconception that C-14 dates are absolute." ↩

2. "It was the Belgian textile specialist at Ghent University, Gilbert Raes, who, in 1973-1974 studied a sample removed from the Shroud in 1973 and published his findings of cotton spun inside the linen yarns. (25). Later, however, the French textile expert, Gabriel Vial expressed his opinion, following his own examination of the Shroud, that the cotton was superficial on the cloth--not spun inside and therefore not really relevant to the issue. The reason for this lack of clarity is that, in fact, there is a lot of extraneous cotton on the surface of the Shroud. This is verified in my own studies of the Max Frei sticky tapes taken from the Shroud in 1978... One has to carefully discern the difference between the fibers from the cotton gloves Max Frei was wearing from the other extraneous cotton found on the tapes.  Usually this can be determined by the coloration and the length of fibers. Whereas the cotton from the Frei gloves [incidently, the white gloves he wore were borrowed from STURP (Personal communication, R. H. Dinegar)], other cotton will be an off-white or even a beige to “brownish” cast. And sometimes even dyed or pigmented cotton fibers will be seen. The fibers are rarely more than a few millimeters in length on the tapes. All these are clearly surface phenomena)." ↩ ↩

3. "I was in attendance at the New London, Connecticut conference held on Oct. 10-11 of 1981. I distinctly remember a remark made by Joan Janney (now Mrs. Ray Rogers) that STURP found cotton spun into the linen threads in the Raes Corner/radiocarbon sample area of the Shroud.  I recently consulted with Barrie Schwortz about this and he confirmed that STURP was finding a lot of cotton inside the linen yarns there as opposed to the main body of the Shroud were none was found.  But this discovery was poorly understood then and so it was thought that the “Raes’ Corner” area would not make a good candidate for radiocarbon test samples which was then being designed by a committee headed up by the late Robert Dinegar.  It clearly raised the question over whether any sample from that corner would be considered homogeneous and therefore suitable for testing."
   "On March 22, 1988, nearly a month before the April 21 sample removal session, I sent a copy of this paper to Pope John Paul II... a minimum of three samples must be taken from three different areas on the Shroud." ↩ ↩ ↩ ↩ ↩ ↩ ↩

4. On page 14, Maloney shares a personal communication from STURP lead chemist Ray Rogers:
   "I believe that important amounts of cotton exist in the sampling area.  There is a big difference in importance between a few foreign cotton fibers found on the outside of a sample and cotton mixed throughout the sample.  I have found copious amounts of cotton at the core of all of the yarn segments I have dissected." ↩ ↩

5. Chemist Ray Rogers provides a comment to Maloney on page 38: "Remember there are blood spots all over the cloth, and sulfoproteins evolve H2S at low temperatures and they evolve hydroxyproline through roughly the same temperature ranges. Only blood spots near the scorches showed degradation. Your figure 3 shows a t/T curve. The same applies to the other compounds on the cloth. For example, pentose impurities on the non-image areas A (or even the hexose ketoses) would have shown degradation within 4 hrs at 100C." ↩

6. "The manual [Frenway System of French Reweaving] shows with drawn illustrations and with clearly written text each step one must take to reproduce the technique known as “French Reweaving”. Perhaps the single most significant feature of this method is that it uses no knots and therefore would not likely show up clearly on the x-rays unless one knew what they were looking for."
   ...
   "To this information Linda Eaton, curator for textiles at the Winterthur Museum adds: '…high quality re-weaving would not have knots on the back, but it is immensely difficult, if not impossible, for it to be done so that it remains invisible to close and careful examination, with or without a microscope. This is not something that you can do from photographs, either, as sometimes it is so good that you have to feel it too.'" ↩

1. "The patterns seen in Figure 1 are all distinguishably from one another clearly indicating differences in their chemical composition.  These compositional differences were further confirmed by peak frequency analysis utilizing the computer software that generates the spectral data.  In particular the radiocarbon samples are not representative of the non-image samples that comprise the bulk of the cloth.  This difference was also supported by the scanning elecron microprobe data that showed gross enrichment of the inorganic mineral elements in the radiocarbon samples, even compared to the waterstain fibers taken from the bulk of the cloth.  In fact, the radiocarbon fibers appear to be an exaggerated composite of the waterstain and scorch fibers, thus confirming the physical location of the suspect radiosample site and demonstrating that it is not typical of the non-image sections of the main cloth.  How much these differences in chemical composition actually affected the accuracy of the radiodate is not clear... considering the presence of the selvage edge, this area may contain newly woven material as a repair." ↩ ↩

2. Page 85:  "Numerous copies of the Shroud of Turin exist and it has now been thoroughly historically documented that several of these painted copies were "sanctified" by being pressed to the original.

1. Page 191:  "All threads from the Raes sample and the yarn segments from the radiocarbon sample show colored encrustations (or coatings) on their surfaces (Figs. 2 and 3). The coating material is not removed by nonpolar solvents, but it swells and dissolves in water. There was absolutely no coating with these characteristics on either the Holland cloth or the main part of the shroud.  When Raes and radiocarbon-sample threads were teased open at both ends with a dissecting needle, the cores appeared to be colorless, suggesting the color and its vehicle were added by wiping a viscous liquid on the outside of the yarn.  A marked difference between inside and outside fibers is characteristic of both the Raes and radiocarbon samples.  The yellow–brown coating on the outside of the radiocarbon warp sample is so heavy that it looks black by transmitted light." ↩ ↩

2. "Pyrolysis-mass-spectrometry results from the sample area coupled with microscopic and microchemical observations prove that the radiocarbon sample was not part of the original cloth of the Shroud of Turin. The radiocarbon date was thus not valid for determining the true age of the shroud." ↩ ↩

3. Page 192:  "The presence of alizarin [a red pigment from madder root] dye and red lakes in the Raes and radiocarbon samples indicates that the color has been manipulated. Specifically, the color and distribution of the coating implies that repairs were made at an unknown time with foreign linen dyed to match the older original material. Such repairs were suggested by Benford and Marino. The consequence of this conclusion is that the radiocarbon sample was not representative of the original cloth." ↩ ↩

4. Page 192:  "Calcium compounds produce blue colors, and a few blue lakes can be seen on some gum-coated fibers. They are removed with 6N HCl." ↩ ↩

5. "The presence of aluminum in the coating material is consistent with the results of Adler, Selzer, and DeBlase, who performed X-ray elemental analyses on different shroud materials, including fibers from radiocarbon-sample warp threads. They reported concentrations of aluminum on the radiocarbon sample 20-times those on shroud fibers." ↩ ↩

6. "When Raes and radiocarbon-sample threads were teased open at both ends with a dissecting needle, the cores appeared to be colorless, suggesting the color and its vehicle were added by wiping a viscous liquid on the outside of the yarn. A marked difference between inside and outside fibers is characteristic of both the Raes and radiocarbon samples. The yellow–brown coating on the outside of the radiocarbon warp sample is so heavy that it looks black by transmitted light (Fig. 2). Chemical tests on both the radiocarbon and Raes samples show their coatings to consist of a plant gum containing alizarin dye present in two forms. Some is dissolved in the gum, giving it a yellow color." ↩ ↩

7. Page 191: "The radiocarbon sample contains both a gum/dye/mordant coating and cotton fibers. The main part of the shroud does not contain these materials." ↩ ↩

8. Page 191 left:  "The Raes threads, the Holland cloth, and all other medieval linens gave the test for vanillin wherever lignin could be observed on growth nodes.  The disappearance of all traces of vanillin from the lignin in the shroud indicates a much older age than the radiocarbon laboratories reported... No samples from any location on the shroud gave the vanillin test." ↩ ↩ ↩ ↩ ↩

9. Page 192, bottom right:  "The fact that vanillin can not be detected in the lignin on shroud fibers, Dead Sea scrolls linen, and other very old linens indicates that the shroud is quite old.  A determination of the kinetics of vanillin loss suggests that the shroud is between 1300- and 3000-years old. Even allowing for errors in the measurements and assumptions about storage conditions, the cloth is unlikely to be as young as 840 years" ↩ ↩ ↩

10. Page 192:  "A gum/dye/mordant coating is easy to observe on Raes and radiocarbon yarns. No other part of the shroud shows such a coating. The early thermal evolution of furfural during pyrolysis/ms analyses, the relatively easy water solubility, the yellow color formed with iodine, and the easy hydrolysis suggest gum Arabic... Its presence as a major component in the coatings on the Raes and radiocarbon samples is not a surprise, because it has long been a common vehicle in tempera paints. The radiocarbon sample had been dyed. Dyeing was probably done intentionally on pristine replacement material to match the color of the older, sepia-colored cloth." ↩

11. Page 193:  "The dye found on the radiocarbon sample was not used in Europe before about a.d. 1291 and was not common until more than 100 years later." ↩

12. Page 192:  "The gum coating was quickly hydrolyzed by either concentrated HCl or 2N NaOH."

1. "The administrators of the radiodate sampling, L. Gonella and G. Riggi, kindly provided three threads from the radiocarbon sample for our study. Two were warp threads from the outer and inner edges of the trimmed sample and the third was a -weft thread from the middle of this sample. Five fibers were taken from each of these samples for comparison with those collected from the sticky tapes. Interestingly, under microscopic investigation, these samples resembled exaggerated versions of the waterstained specimens. They were non-fluorescent, unevenly colored from dark yellow to splotchy brown, roughly surfaced (even showing patchy encrustations in spots) and showed a very strong and variably multicolored birefringence pattern. Considerable microdebris was also evident."
   ...
   "[A] great deal of variability was evidenced in the radiocarbon samples. Some of the patchy encrustations were so thick as to mask the underlying carbon of fibers whose continuity were clearly obvious in the microscope images." ↩ ↩

2. "It should be noted that there is more variation in the patterns of the radiocarbon samples representing an area of a few square centimeters than in those of the non-image samples taken from areas a whole body-image length apart."
   ...
   "The peak patterns and relative intensity patterns in other regions of the spectra are also consistent with the conclusion that the spectral patterns of these fibers are all distinguishably different from one another. Note this is specifically true for the radiocarbon fibers and the non-image fibers from the bulk of the cloth, thereby demonstrating that the area selected for the radiocarbon sampling is atypical and is not clearly representative of the rest of the Shroud." ↩

1. Page 2:  "The thread has a yellow-brown coating with the exception of indented regions which are white. These indented regions are at the intersection with the warp [vertical] thread. The weave was tight enough that the application of a relatively viscous gum/mordant/dye solution did not penetrate the intersection of the threads.  This would appear to be obvious evidence of a medieval artisan’s attempt to dye a newly added repair region of fabric to match the aged appearance of the remainder of the Shroud." ↩ ↩ ↩ ↩

1. "The three samples that we looked at have cotton and were taken from the carbon dating area. The main shroud is linen. Ray Rogers identified cotton in the Raes thread and the radiocarbon fibers. Cotton fibers can easily be identified because of their flat tape-like shape and presence of several reversals and twists, about 1.2 millimeters apart and the absence of bamboo-like growths as evidenced in linen. In general, flax fibers vary in length from 20-350 centimeters while cotton is about 1.5 to 5.5 centimeters. Clearly there is no cotton in the main body of the Shroud cloth."

The density variations of the material are apparently associated with the Shroud, because they are not visible in the cut-out portion in which only the backing cloth is present. The distinct weft structure is continuous across the seam joining the two panels and strongly suggests that the side strip and the main section were of a single manufacture." ↩

1. "The fabric from the main piece, designated as Piece I, and that from the added strip, designated as Piece II, were examined separately... It must be pointed out, however, that in some of the preparations from the warp as well as from the weft of Piece I, traces of cotton fibers were observed.  It would seem that the linen threads had been spun where cotton had also been spun... It has sometimes been remarked that these were superficial fibers having come upon the Shroud at times of the numerous expositions. If this were the case, it is scarcely probable that all the cotton fibers would be of the Gossypium herbaceum variety." ↩ ↩

"Managing director Peter South explains: 'It was while the sample was undergoing tests at the radiocarbon acceleration unit in Oxford that Professor Edward Hall noticed two or three fibers which looked out of place. He mentioned this to his friend Sir James Spooner, chairman of Coats Vihella, to which our firm belongs. Consequently, after several telephone calls, the minute samples, which looked like human hair, were sent to us.' The strange fibers were magnified 200 times under a microscope and were immediately identified as cotton. 'The cotton is a fine, dark yellow strand, possibly of Egyptian origin and quite old. Unfortunately, it is impossible to say how it ended up in the Shroud, which is basically made from linen,' said Mr South. "It may have been used for repairs at some time in the past, or simply became bound in when the linen fabric was woven. It may not have taken us long to dientify the strange material, but it was unique amongst the many and varied jobs we undertake." ↩ ↩

9. Page 17:  "The outside of Raes thread #14 showed the heaviest encrustation and deepest color of any of the samples. The encrustation is heaviest on cotton fibers, it is the vehicle for the yellow-brown color, and it suggests that the cotton was added to enable better control of dyeing or staining operations. When I teased threads open at both ends with a dissecting needle, the cores appeared to be nearly colorless. This observation suggests that the color and its vehicle were added by wiping a viscous liquid on the outside of the yarn in order to match the color of new material to the old, sepia color of the Shroud."" ↩

10. "The Raes samples show a unique splice. Raes thread #1 (figure 17) shows distinct encrustation and color on one end, but the other end is nearly white... Fibers have popped out of the central part of the thread, and the fibers from the two ends point in opposite directions. This section of yarn is obviously an end-to-end splice of two different batches of yarn. No splices of this type were observed in the main part of the Shroud." ↩

12. "We had been puzzled by the Raes report at the time of the 1978 STURP observations in Turin. We could not find more than traces of cotton on the cloth. The Shroud appeared to be pure linen. We used cotton gloves during the STURP studies of 1978 to protect the relic, and they could have been responsible for the traces of modern cotton found on a few Shroud sampling tapes. Samples from the main part of the cloth are significantly different from the Raes samples with regard to cotton content." ↩ ↩ ↩

"After conducting analysis at high vacuum with the ToF-SIMS, the 'spliced thread''broke into three distinct pieces; a fuzzy end (Region 1), a tight woven end (Region 2), and a micro-sized circular cocoon-shaped brown crust that seemed to be connecting the two end pieces. The ToF-SIMS results were the first to show that the spectra from the two ends were similar to cotton rather than linen (flax)... The results of the FTIR analysis on all three threads taken from the Raes sampling area (adjacent to the C-14 sampling corner) led to identification of the fibers as cotton and definitely not linen (flax).

Note that the paper is not peer reviewed and Theimberger admits in the acknowledgements "I am not an expert," but thanks those who were who helped him with the paper. ↩ ↩

1. In Part 3:   "First, it must be recalled that Gilbert Raes found no cotton in Piece (or Part) 2 of his sample contrary to Piece 1. Piece 2 was the smallest part of his sample and was in the so-called “side-strip” of the Shroud. Different studies have shown that the side-strip pertains to (or at least is continuous with) the original Shroud." ↩ ↩

2. From the Appendix which was written by Giulio Fanti and sent to Heimburger in 2009:  "Giulio Fanti studied many fibers and threads coming from the TS (Turin Shroud); in particular fibers coming from dusts vacuumed from the back of the TS in correspondence of Face, Hands, Buttocks, Feet and 1988/C-14 area were compared among them and with threads coming from the 1988/C-14 area (in proximity of the “Riserva” sample)... From a first sight, looking at an optical microscope at 150x-600x no cotton fibers, such to hypothesize an external contamination, were easy to see on the threads surface... From Figures F2 and F3 it is not easy to detect the possible presence of cotton fibers also because it is possible the presence of some pieces of defective linen fiber that could be perhaps confused with a cotton fiber. In any case with higher magnification 4 cotton fibers were detected in F15001 TS thread, see Figure F4. They are parallel to the linen fibers and this fact leads to think that the cotton fibers were woven together with the linen fibers. The relatively small percentage of cotton fibers of (4/188=) 2.1% is in agreement with the hypothesis that cotton was a contaminant in the ambient where linen threads were prepared."
   Mirrors:  Archive.org ↩ ↩ ↩

3. In the beginning of Part 1, Heimburger explains where Ray Rogers obtained threads and fibers from various parts of the Shroud:  "In 1978, as member of the STURP team and professional chemist at Los Alamos National Laboratory (LANL) until 1988, Raymond Rogers took 32 adhesive-tape samples from all areas of the Shroud (some were from the Holland backing cloth and patches). In 1979, he received 14 yarn segments of the Raes sample from Prof. Luigi Gonella. The Raes threads were photographed and labeled from Raes #1 to Raes #14. According to Rogers, it is likely that all of them were from Piece 1 of the Raes sample. Finally, on December 12, 2003, Rogers received “samples of both warp and weft threads that had been taken from the radiocarbon sample by Professor Luigi Gonella before it was distributed for dating. He [Prof. Gonella] reported that he excised the threads from the center of the radiocarbon sample. A “chain of evidence” has been maintained on those threads, and it is certain that they were truly removed from the radiocarbon sample.” ↩

4. Last page of part 1:  "there is about 28% of cotton in R7A (14/50), 12% in R7B (2/17) and no cotton in R7C (0/30). The total amount of “complete” cotton fibers in the outer part of R7 is therefore about 15%... This “old cotton”, even if it is found in the outer part of the thread, is clearly not a contamination. It is part of the thread. All cotton fibers are similar and from the same species and are very different from modern cotton." ↩

5. In Part 3:  "Cotton fibers are not at all evenly distributed: taking in account only the more or less “complete” cotton fibers (i.e., fibers forming long bundles or sometimes “nodes” or individual relatively long fibers) there is about 15% of cotton in the outer part (from 0% to 28% depending on the location studied) and about 10% of cotton in the core of the thread. In addition many short pieces of broken cotton fibers are found everywhere. ↩ ↩

6. In part 3: "It is impossible to see the cotton on the whole tight thread “as received”, even with polarized light microscopy: it is necessary to separate many fibers... High resolution microscopy (at least about 400x) is necessary to differentiate with a high degree of certainty this old cotton from some particular types of flax fibers." ↩ ↩ ↩

1. "Cotton fibers were observed on three occasions, with one isolated shown in Figure 4... The presence of a few cotton fibers is not unusual. It is possible cotton fibers are present from wrapping the textile in a cotton cloth, a practice that is still used in textile storage. It is also possible that processing of the fibers or the loom contained remnants of cotton fibers, which contaminated the shroud. We can also state that the linen fibers observed in this study have only low levels of contamination by a few cotton fibers, consistent with the original observations on the shroud (e.g. Raes 1976) that there are a few cotton fibers on (or in) the shroud." ↩ ↩

2. Rogers writes:  "With the Shroud, neither the radiocarbon investigators nor the authorities in Turin have cooperated in attempts to resolve the ‘dating problem.’ The church officials appear to be content to have society view the Shroud as a medieval hoax, and the radiocarbon laboratories have refused to consider the possibility that they were given a spurious sample.  In a manner uncharacteristic of rigorous scientists, they refuse to allow observations on retained samples. They also refuse to do their own simple chemical observations. They refuse to discuss or show any photomicrographs of samples they might have."

1. "Perhaps more compelling is that most of the shroud lacks vanillin, a breakdown product of the lignin in cotton fibres. There is vanillin in the Holland cloth, and in other medieval linen.

Page 10, bottom left: "not only is the Raes and C-14 sampling region anomalous in comparison to the main Shroud cloth, but the piece of Holland cloth in the ventral [front] corner is also significantly different from the rest of the Holland cloth. The most probable scenario is that the original smaller section of Holland cloth was extracted for relics. This section was most likely replaced with newer material that did not match the exposed dorsal section of Holland cloth. Also consistent with the data is the hypothesis that the person(s) responsible for taking this section of Holland cloth also extracted a small section of main Shroud cloth directly adjacent to the side seam and missing ventral corner, e.g., the C-14 sampling area (see Figure 13; additional details available in reference 2). To hide the extraction, the missing material would have been patched and surfaced dyed, along with the newer backing material, such that it would not have been detected." ↩ ↩

Franco Faia recounts:  "Unfortunately, Gove, perhaps he didn't realize, was sometimes playing both sides without knowing it.  Sometimes in his thoroughly researched book there are examples of tremendous ingenuity.  At Trondheim [a meeting between six radiocarbon labs] he [Gove] was maneuvering to try and exclude STURP." ↩ ↩

4. At 45:43, forensic medical expert Pierluigi Baima Bollone recounts: "A French Monk named Bonnet-Eymard asked the radiocarbon dating laboratory in Arizona to show him the photograph of the piece of the Holy Shroud that was examined.  That photograph is not the Holy Shroud.  Recently I found out from the well-known German theologian Professor Werner Bulst that he too had obtained a photograph of the little piece of the Holy Shroud examined by the Zurich laboratory.  According to what Werner Bulst told me this second sample does not correspond to the Holy Shroud's textile implantation." ↩ ↩

5. At 20:44 in the documentary, experimental technician Franco Faia recounts how Harry Gove used deceptive tactics to orchestrate the Carbon dating procedure at the three labs, while hiding his influence:  "He [Gove] involved the head of the British Museum getting him to sign something without being aware of what it was, etc, etc.  From all over the world, the Church was blackmailed, being told, 'Either you let us examine it, or else it means you're scared and it's false!"
   "And there is even proof in Gonella's archives that the three laboratories sent three absolutely identical letters with the same text, written, obviously, on three different typewriters from three different addresses, but the text was identical to that sent by Gove.  But what was even more serious is that the letter from the Zurich laboratory from Professor Willi Wolfli has the address of Zurich Polytechnic, CH, etc, but it was posted in Rockchester [New York].  In other words, Professor Harry Gove had an envelope sent to him, he posted it, it's postmarked, to give you an idea of the level we had sunk to." ↩

6. At 37:01, "The Daily Telegraph of 25 March 1989 spoke of a million pounds donated to the Oxford laboratory by 45 businessmen and rich friends.  The money was then used for the establishment of a new chair of archaeology, that was filled by Michael Tite." ↩

7. Protestant minister David Sox, who was present at the Zurich lab, wrote a book about how the shroud was a fake, publishing it only two weeks before Oct 13, 1988 when the 1988 carbon date was announced.  He wrote about how Z3 (supposedly from the mummy) had a twill weave and Z1 (supposedly the Shroud) was slightly lighter than previously measured:  "The next step was the most difficult.  Carefully Jaggi removed the tiny pieces of aluminium, and each small sample of linen was placed in plastic containers and weighted in a high precision weighing scale, Mettler AE 163.  Wolfi noted the sample Z1 appeared minutely smaller than Turin's calculations.  'Mouisture loss in flight?' someone suggested.  The others corresponded to the previous calculations made on 21 April in Turin.  The samples were photographed by normal and microphotography.  By this time Wolfi and several others had a good look at the three.  Anyone who knew the texture of the Shroud was aware which was from the Relic, Wolfi joked.  All you would need is to look at the pictures in the National Geographic.  It didn't take me long to know--Z1.  Z1 and Z3 were both twill weave.  Z2 was a tabby weave like mummy cloth.  Unlike Z1, Z3 had irregular edges.  Z1 was a carefully trimmed piece as if to make absolutely clear it was an exact third."  The video shows this segment at 46:35 and 46:52. ↩ ↩

Bill [Meacham, an archaeologist] pointed out all the things that you could screw up if you didn’t have an archaeologist involved in the sampling, to advise you what to do and what not to do.  And a chemist, to tell you what to do and what not to do, before you start sampling. That was all in the original protocol. They didn’t follow it." ↩ ↩

A prominent Shroud researcher, who does not want to be identified, has told only afew other Shroud researchers, including myself, about a curious phone call he had received oneday at about 1:30 in the morning. His recollection was that it was not long after the C-14 datingresults were announced in October 1988 and sometime in the spring. I will call the researcher“Harry.” Harry indicated the (male) person, who did not apologize for calling so late, sounded distraught. The person told Harry he had been involved in falsifying the results of the 1988 dating. Harry thought the accent might have been German and thought the person may have been in his 40s but wasn't sure because of the accent and emotional nature of the call. The person would not reveal his name (the person claimed it wasn't important) or from where he wascalling. He kept asking Harry if he would forgive him for having done a disservice to humanity. The person even mentioned the word "espionage" in relation to the event. The only detail he gave about the procedure was saying that the real Shroud sample was thrown in the trash. Harry tried repeatedly to get the man to identify himself and when he tried to get more details, the man said he couldn’t say more as he could get in some real trouble. Harry said the person said he also planned to call other Shroud researchers, but as far as we know, no one ever did receive a call. Harry has wondered over the years whether the call itself could have been a fraud, but he is firm that the person sounded distraught to the point that Harry said he wouldn't have been surprised if the guy would have said "I've got a gun and I'm going to shoot myself."  Even now, Harry just isn't sure what to think." ↩

Berchi, M.  "Un test molito indiscreto."  in Il Sabato, November 19-25.  1988.On Page 29. Cited and translated by Emanuela Marinelli.  Marinelli writes:  "[Luigi] Gonella [professor of Physics Instrumentation at the Polytechnic of Turin and scientific consultant of the Cardinal] accuses the laboratories of 'intoxication by success' and adds: 'Misconducts there were tons. The colleagues of the 14C behaved in a disgusting manner. Those scientists have hatched a true plot to discredit the Shroud. At first, when they did ask us to examine a sample of the Shroud, assured us of the utmost seriousness and completeness of the analyses, along with the collaboration with the Custodian of the Shroud, that is the Bishop of Turin, and his scientific advisor, i.e. the undersigned. Driven by celebrity fever, those scientists began to turn their backs on their own commitments: no more interdisciplinary examinations, only 14C. They flooded even Rome with pressures so that Turin had to accept their conditions. They used the then president of the Pontifical Academy of Sciences, professor Chagas, to get the undersigned out of the way and go their own way”. It is natural to ask Gonella: then why did the Holy See and Cardinal Ballestrero accept it? 'Because Chagas - the professor of the Polytechnic says - acted alone, bypassing other academics. The Vatican was continually threatened by the laboratories themselves, who went on repeating: if you don’t leave it to us, only to us, the results will not be acceptable. So, in the end, Ballestrero had to surrender, though suffering badly. And I to submit. Also because these gentlemen did everything to support the argument that the Church was throwing a spanner in the works of science.'  Gonella explains: 'It was blackmail. They put us up against the wall just with a blackmail. Either we accepted the test of 14C on the terms imposed by the laboratories, or it would break out a campaign of accusations saying the Church fears the truth and is an enemy of Science.'" ↩ ↩

Petrosillo, Orazio.  "Clandestine Sample."  The Holy Shroud is Authentic.  1989.  Mirrors:  Local copy.  "The removal of eight square centimeters from the Shroud cloth took place on the 21 April 1988 in the sacristy of the duomo of Turin in the presence of thirty or so people among whom were the guardian of the piece, Cardinal Anastasio Ballestreror, the scientific guarantor of the operation of curator of the British Museum, Michael Tite, as well as seven representatives from the three laboratories."
"On a souvenir photo of the sample-taking, we see Tite with a tray on which have been placed the nine small containers.  The third control sample - the one we have designated as semiclandestine - is not there.  Giovanni Riggi, who actually cut the fragment from the Shroud, describes in his 'Rapporto-Sindone' every phase of the operation but makes no mention of a third control sample.  Yet the day following the sample-removal, an official communique was sent to the Holy See, the owner of the Holy Shroud, in which there was mention of a 'sample provided as an additional control," without specifying where it came from.'"
"Tite turned to Jacques Evin, director of the Radiocarbone laboratory of the University of Lyon, requesting a sample of mediaeval cloth from the 13-14 century, resembling the Holy Shroud as closely as possible. After a laborious search, Evin found in the cope [cloak] of Saint Louis d'Anjou the sample corresponding perfectly to Tite's request: made of linen, of herringbone weave, yellowed with age and from the end of the 13 Century." ↩ ↩

1. Michael Tite said, "A mediaeval sample is very difficult to find. There was none in the British Museum that we were permitted to destroy. I asked Vial, Evin, Wilson and others. When I arrived in Turin I learned that Evin had found some mediaeval threads." ↩

2. Michael Tite is asked "Why was the blind test not carried out according to the protocol?"  He responds:  "There were two aspects. We decided in January that we would rather not have a blind test because that could be done only by unravelling the samples, and that makes it much more difficult to clean. The decision to abandon the blind test was made in Turin at the moment of the cutting. As for Ballestrero and I going into a separate room, that was quite unnecessary." ↩

   Thank you very much for your most helpful and encouraging letter of February 8. Certainly, limiting the number of laboratories involved in dating the Shroud makes my task somewhat easier. I would certainly very much welcome any assistance that you can give in obtaining a mediaeval control sample, which is as similar as possible in terms of weave and colour as the Shroud, since at present, I am not certain whether the British Museum will be able to provide such a sample. Firstly, therefore, to answer your specific questions:
   1: The total sample would need to be 6 sq. cms, (i.e. about 120 mg)
   2: The material of the sample should be linen. I enclose a photocopy of some photographs which give some indication of the weave of the Shroud.
   3: We are looking for a sample which dates from the 13th or the 14th century AD., preferably the latter.
   4: The historical precision should obviously be as good as possible, but one would certainly consider samples with an age range of fifty to a hundred years.
   5: There is no need for the sample to come from a well known piece of textile.
   6: I suppose that I could come to France to collect the sample. The idea certainly appeals to me. But I do not really think this would be necessary. It would probably be satisfactory to use the postal service.
   7: I think that one would want to include the name of the museum that provided the sample in the final publication, if this was at all possible.
   On the basis of these answers, it would seem that your third suggestion as a source of possible material, that is, the Cluny Museum in Paris, would be most suitable. I have therefore written a letter to Mme. Joubert-Caillet — copy enclosed — asking her if she would be able and willing to help in this matter. Again, thank you very much indeed for your kind offer of assistance, which is very much appreciated. As you say, I hope that the project will give us an opportunity to meet again.
   With best wishes,
   Yours Sincerely,
   Signed: M. S. Tite." ↩ ↩

So he and one, Gabriel Vial, went along to the Basilica of SaintMaximin at Var and pulled some tufts out of the cope known to have been worn by St. Louis d'Anjou (d. 1297)."

1. "The same New York Times article states that an unnamed French monk charged that the British Museum official who coordinated the radiocarbon measurements substituted snippets of 14th century cloth for the postage-size shroud samples. The only time the samples removed from the shroud in the Sacristy at Turin Cathedral on the morning of April 21, 1988 were out of the sight of representatives of the three laboratories was when they were taken to the adjacent Sala Capitolare to be divided and sealed inside numbered stainless steel containers (Donahue, pers commun June 1989). During this time only the representative of the British Museum and the Archbishop of Turin were present (Damon et al 1989).  In addition to this charge by the unnamed French monk, serious questions have been raised by R Halisey (pers commun Aug 14,1989) as to why the sampling of the shroud and the sealing of the samples took place in two separate locations since that opens the possibility that a substitution could have been made of the shroud samples. This sample sealing procedure was apparently not videotaped although all the other operations were (Damon et al 1989)." ↩ ↩

Part II"  2016.This paper is not published in a peer reviewed journal, but author Joe Marino is a leading experts on the shroud of Turin, prominent for first discovering evidence the radicarbon dated corner of the shroud was in a rewoven / repaired area. He describes his credentials as of 2022: "I have studied the Shroud of Turin for over forty-five years and innumerable hours. I have read all the major works on it in the English language. I have written two books and dozens of articles about it. I have made presentations at international conferences and know some of the scientists that did hands-on testing of it. I have one of the largest personal English-language collections of Shroud materials in the world and make it a point to scour the Internet for the latest information constantly. The Shroud is something I think about a lot. It is a solitary focus in my life." ↩ ↩

1. Marino writes:  "Ballestrero and Tite took the samples into a private area, out of view of all the people in attendance and of the camera, and put them into vials labeled with numbers. These vials were then brought out and presented to the representatives of the three labs. This secrecy gave rise to the allegation, quite  8 absurd on the face of it, that Tite had conducted some sleight of hand and switched the real Shroud samples with others of medieval age. There are still quite a few Europeans who believe to this day that the samples were substituted and the C-14 date that was later obtained is not from a piece of the Shroud." ↩ ↩

1. Schwortz comments:  "Even Dr. Jull admitted to me that the 1988 tests were rather poorly performed. Arguing over the sample site, leaving the room for 30 minutes and returning with sealed, stainless steel (opaque) containers rather than glass, failure to perform chemical analyses on the samples (required by their own protocol) or release the raw data or explain mathematical inconsistencies in the process, etc., etc., have led to many conspiracy theories. I still personally prefer to look for a credible, scientific answer (like the reweave theory) than to resort to conspiracies." ↩ ↩ ↩

2. Schwortz comments: "To date, I have received no answer from Dr. Jull to the several e-mails I sent him to follow up on photographing the remaining sample. I am still prepared to photograph it should it be made available. According to the experts I spoke with, most labs would never destroy or use all of an existing sample but would typically keep some small pieces in reserve."

2. Page 176, bottom:  "Rogers also fails to understand that his radiocarbon samples were on the edge of a water stain.  This, too, was not only stated by Vernon Miller from his above examination in 1989, and supported by STURP chemist, Alan Adler, by his above examination in 1996 and 1997, but the normal photograph of this region taken in 2002 during the Shroud's restoration clearly shows this in fig 125.  The edge of a water stain is where much of the depris acquired by or contained in the flow of water is going to be deposited.  Adler's FTIR and scanning electron microprobe date shows gross enrichment of the inorganic minteral elements in the radiocarbon samples.  Adler stated, 'In fact, the radiocarbon fibers appear to be an exaggerated composite of the water stains and scorch fibers.'  Both the water stain's edge and the scorch at this location would better explain the different chemical composition of the samles than an undocumented, invisible reweave neer seen by the eyes of scores of experts or photomicroscopy.  The edge of the water stain at this location also means the cloth material at the radiocarbon site had to have been present when the water flowed over this and its adjacent areas.  (Making an invisible reweave or spices without permanent attachment is difficult enough, but even reweave advocates do not contend the original Shroud material had a water stain that was replaced with new material also containing a perfectly matching water stain.)  However, as seen in Chapter Four, evidence and anaysis presented by photographer Aldo Guerreschi and Michele Salcito at international conferences held on the Shroud in Paris in 2002 and in Dallas in 2005 indicate that these particular water stains are not from the fire of 11532.  The authors show that when the Shroud is folded so that its burn hoels and scorch markes from the fire of 1532 line up over each other within its folds, many water stains on the cloth also line up within this folding pattern.  However, the water stains along the bottom row ofthe Shroud, including the one just off the letter A in Fig 126., and other water stains on other parts of the Shroud, do not line up with thos fold configuration.  According to the authors, these water stains line up in an accordin style fold patter while the long cloth was kept inside a container, which acquired a small amount of water on the bottom. SEe Figs. 127-130.  This indicates the Shroud was in two different folding configurations at the time it received the two different sets of water stains.  The Shroud's history in Europe since the 14th century is well documented and no staining incidents other than the 16th century one in 1532 are recorded.  Unlike the water stains from 1532, the stains near the radiocarbon site are not associated with any fire or other damage requiring the Shroud to be repaired.  These water stains have occurred centuries earlier."  Fig 125 photo Copyright 2003 ODPF. ↩

3. Page 176, top:  "Yet, if the Raes samples (the only non-image area from which Rogers used a sample) were in a lightly scorched area, as the radiocarbon samples were, bonds broken during the scorching of the cellulose may have allowed furfural to be released at lower temperatures.  This, Rogers' subjective observations and interpretations are the primary support for his erroneous conclusions."  Note:  Antonacci is incorrect to say Rogers' only non-image fibers were from Raes threads.  He also had threads from the carbon-dated sample area and various places on the main body of the Shroud. ↩

4. Page 175:  "They [UV fluorrescant photographs] revealed that Rogers' samples from the radiocarbon site were in the middle of a scorch mark.  This observation was made in 1989 by Vernon Miller, chief photographer of the 1978 Shroud investigation, after examining the above imaging.  It was also confirmed by STURP chemist, Dr. Alan Adler, who compared 15 threads from the raciocarbon area with 19 fibers from non-image, image, water stain, scorch, backing cloth and serum-coated locations on the Shroud by Fourier Transform Infrared (FTIR) micro spectrophotometry and by scanning electrom microprobe.[27]"  For source 26, Antonacci cites his previous book, "The Resurrection of the Shroud" (2000) pages 168 and 304.  For source 27 Antonacci cites "Updating Recent Studies on the Shroud of Turin" by Alan Adler in 1996, "Concerning the Side Strip on the Shroud of Turin" by Adler in 1997, and personal communication with Adler in 1998 and 1999.  However, Adler's 1996 paper posits (contra Antonacci) that the carbon dated corner "may contain newly woven material as a repair."  Likewise the in the 1997 paper, Adler speculates, "Maybe the radiocarbon sample is simply rewoven material from the time of this repair [made by the De Charney family]." ↩

1. Barrie Schwortz recalls his 2012 visit to the radiocarbon lab in Arizona:  "At the beginning of the summer I was contacted by Helmut Felzmann, noted Shroud researcher and author from Germany. He asked if I would be willing to go to the University of Arizona Radiocarbon Dating Laboratory in Tucson, Arizona, one of the three labs that dated the Shroud in 1988, and photograph their remaining samples. As you probably know, each of the three laboratories saved some of their original samples and kept them in reserve. This included not only the remaining Shroud samples, but the remaining reference samples as well.  Helmut was researching the samples and had already contacted Dr. Timothy Jull, the current Director of the laboratory, to make the preliminary arrangements for the samples to be photographed.  The day I was to make the photographs, Dr. Jull informed me that one (or more?) remaining samples would not be available for the photography session. These were currently in the possession of Dr. D.J. Donahue, the retired former Director of the laboratory, who was away due to a family emergency. I am hopeful they can be made available at some future date so they can be photographed using the same techniques and equipment and added to the collection." ↩

Ramsey writes:  "As yet there is no direct evidence for this - or indeed any direct evidence to suggest the original radiocarbon dates are not accurate.  There is a lot of other evidence that suggests to many that the Shroud is older than the radiocarbon dates allow and so further research is certainly needed. It is important that we continue to test the accuracy of the original radiocarbon tests as we are already doing. It is equally important that experts assess and reinterpret some of the other evidence." ↩

1. From the carbon dating section on page 48:  "We request permission to take samples from several different non-image locations on the Shroud.  Two hundred milligrams (200mg) from each of the burned areas under and aroudn the patches (excluding the dorsal shoulder foldmark intersection area) will be trimmed away.  This material can be removed without affecting the visual appearance of the relic or causing damage to the fabric structure.  Conservatively, this quantity will provide three samples for each participating laboratory.  We also request 200-mg samples from the presumed side strip, one patch, and the lower right-hand corner of the Shroud.  Each sample is the equivalent of about two square inches (10 cm²) of material  We also request a 200-mg-sample from the Holland backing cloth.  This latter forms an internal standard of known date to go with our unknown." ↩

1. Fearing that the Shroud's reputation was about to be totally ruined by a very poorly planned and quite possibly incorrect carbon dating, I composed a letter to the British Museum...  3. Why did it agree to only one sampling site, thereby raising the possibility of an anomalous zone being dated?  4. Why did it agree to the sampling of a scorched area of the cloth, again in conflict with the recommendation of the Turin Commission? ... 6. Why did it not follow its own guidelines in the inter-comparison experiment and insist that samples be taken well away from selvedges? Or is 2-3 cm. considered to be ‘well away’?" ↩ ↩

1. "The fact that the white light photographs show a different coloration in this area, along with the UV fluorescence photography images which clearly show different fluorescence properties in exactly the same areas, coupled with Ray Rogers' detailed chemical and microscopic analyses and the MarinoBenford textile evidence that has been presented over the last few years, all make me believe that the 1988 c14 samples of the Shroud were taken from an anomalous portion of the cloth." ↩

2. "These color images should be interpreted as chemical composition maps... We don't know from the images what these chemicals are, only that they are not the same everywhere. The same color in two locations indicates a likelihood that the same chemistry exists at both locations. Beware that these are radiometrically uncalibrated cameras. One must be cautious in over interpreting them since we had to struggle to get them into a form we could enhance, a process requiring some creativity" ↩

3. "Jean points out that these [spectrographic images] actually indicate differences in chemical composition. So the similarities in the patch in the lower left corner and the areas immediately adjoining it, actually indicate those areas are similar in chemical composition and different from other areas of the Shroud. Of course, we would expect the patches to be different because we know they are made of different material than the rest of the Shroud. However, notice that the area adjoining the patch (where the c14 sample was taken from, and ostensibly part of the actual Shroud) is also mostly the same color of green. This is further convincing, supportive, scientific evidence that this area is inherently different in composition than the rest of the Shroud." ↩

4. "The images were originally r,g,b color separations as you describe. There was a strong illumination brightness falloff from the center. This was eliminated by dividing each image by a flat field. The flat field was composed of the sums of all the images added together, flipped left to right and top to bottom, in all combinations in order to generate a featureless illumination model. After flat field correction the images were flat and, when viewed in color, were gray with slight color variations." ↩

1. Rogers writes "I was given 14 threads by Prof. Gonella, as you can see in the record photograph I sent you --- not 20 as you said 23 October. The record photograph was taken to prove (in court, if necessary) what I had been given: it was not intended to be great art or achieve technical perfection. My reasons for believing that those 14 yarn segments came from the Raes sample are the following: 1) Prof. Luigi Gonella (at that time the Cardinal's scientific advisor) told me they were from the Raes sample, and 2) their cotton content, the variety of cotton, and the textile characteristics agree with those reported by Gilbert Raes in 1973. I believe that the evidence for the sample's validity is much stronger than a supposition based on appearances.  If you doubt the provenience, you should question Prof. Gonella." ↩ ↩

2. Ray Rogers discusses how the radiocarbon corner looks different under fluorescent light:  "The main non-image area of the Shroud fluoresces, as you can see in the upper right part of the photograph. Scorches, water stains, and image do not fluoresce in the visible range of light. The photograph was taken in 1978; therefore, the unfortunate radiocarbon sample had not yet been cut out of the cloth. The area cut in 1988 was immediately above the small, white, triangular area. That white triangle is where the Raes sample was cut in 1973. Notice that the entire area above the Raes sample and along the seam is darker than the main part of the cloth. IT DOES NOT FLUORESCE. That is NOT a shadow. Its chemical composition is different from the Shroud. That is exactly the area sampled for the 1988 dating fiasco.  Although more arcane chemical evidence exists to prove the invalid nature of the radiocarbon sample, I find this photograph especially revealing. The radiocarbon sample was invalid. No strange, magical events are needed to explain the invalid date. I do not know what the real date is, but I know the sample used in 1988 did not yield a valid date. The poor preparation for sampling in 1988, the poor verification of the sample, the failure to follow written protocols, and the unrealistic claims made about "unreliable" radiocarbon dating have done great damage."  Unfortunately, the photo to which Rogers' refers has been lost. ↩

3. "Then, while reviewing my notebook and notes, I noticed that on 27-28 March 1980 I did some testing for pentose sugars on Raes and Shroud samples. STURP was gathered at the Air Force Academy to run tests on the tape samples, Zina thread (which had mysteriously disappeared from its package), and Raes samples. I had hypothesized that it might be possible to detect the glycosidic sugars from S. officinalis on the Shroud, which would prove ancient technology for the linen. I used Bial's reagent (300 mg orcinol, 100 ml con. HCI, and 0.25 ml 10% ferric 11 chloride). It did not perform as claimed in the literature; however, when diluted 1: 1 with water, it gave a test with furfural and authentic pentoses. At the time, we did not know there was a large difference between the Raes sample and the main part of the Shroud: considerable confusion resulted. I am still trying to straighten it out. The Bial's test made me very confused, and we did not come to any final decision regarding the presence of pentose sugars on the Shroud. The facts were that I got some positive and some negative tests on Raes sample fibers. Gum Arabic will hydrolyze in HCI to give arabinose, a pentose sugar. Gum Arabic on the Raes fibers would ultimately give a positive test in Bial's reagent.  Unfortunately, I did not attempt to construct alternate hypotheses, and I didn't pay enough attention to the results." ↩

4. Ray Rogers describes a report from Alan Adler:  "Al Adler obtained three threads from the radiocarbon area from Gonella and Riggi. Two threads were from the warp and one was from the weft. He reported analyses in the Proceedings of the 1998 Dallas Shroud Symposium [or see "The Orphaned Manuscript" by Dorothy Crispino]. He noted that "Some of the patchy encrustations were so thick as to mask the underlying carbon of fibers whose continuity were clearly obvious in the microscope images." The radiocarbon sample certainly had the same kind of polymeric coating I observed on the Raes sample. However, Al also did SEM x-ray analyses on the radiocarbon samples. He found that one warp thread had an aluminum content of 2 weight % while the other contained 1.1 wt%. That is an amazing amount. The weft contained 0.2 wt% aluminum (still high). This agrees perfectly with my observations of a hydrous aluminum oxide mordant being used with the Madder root dye." ↩

5. "[Thread] Number 12 was given to Al Adler. It was a good, long, colored warp thread. I have been told that it was used for an unauthorized attempt at dating. Can anyone comment 9 on that? I had sworn that none of the samples would be used for dating, and all members of STURP were aware of this legal document. Several conflicting claims have been made." ↩

6. Joe Marino comments on an email, "Regarding Rogers’ comment to me in #4 above, it should be noted that the three textile experts Sue and I approached were not told that it was a picture of the Shroud. All independently expressed the opinion that the area had somehow been manipulated. That fact, I believe, gives their opinions more credibility." ↩

7. Ray Rogers wrote in August 2003, "Mechtild Flury-Lemberg did not see the gum layer and was fooled by the color match. She has declared that the radiocarbon-sample area is valid; however, she did not do any analyses. She has completely stopped any communications with the cardinal or any of the other custodians of the Shroud." ↩

8. Ray Rogers wrote, "I would remind you that the diocese of Turin holds most of my original tape samples. Why can't they provide samples? Why can't they provide samples from the 2002 "restoration"? Why can't they get fibers from the threads Baima Bollone cut in 1978? The cardinal's scientific advisor told me (I saved the message) that even he did not have access to my samples. Why?" ↩

9. "Rogers’ own attempts to contact Turin were all met with silence." ↩

10. Ray Rogers wrote in August 2003, "It is highly unlikely that we could obtain additional samples from the radiocarbon area. I cannot get responses from any of the persons in Turin who have access to samples." ↩

1. "Msgr. Ghiberti does not have to rely on my chemistry to observe a difference between the radiocarbon sample and the main part of the Shroud.  He can look at the ultraviolet fluorescence photographs taken by Vern Miller in 1978. They show the sampling area as a dark zone, proving that its chemical composition was not the same as the main cloth. The dark area is not a result of dirt or a shadow. I can explain fluorescence in great detail, but it is based totally on chemical composition." ↩

2. "I received some of the 1973 Raes threads from Luigi Gonella on 14 October 1979. If they were spurious, a person I consider to be a good scientist, Luigi, lied to me. The fact that they agreed with Raes' observations seems to confirm their validity. Their location on the Shroud shows that they must share at least some yarn segments with the radiocarbon sample. They proved to my satisfaction that the radiocarbon sample was spurious. I then received samples of the authentic radiocarbon sample on 12 December 2003. Their composition was identical to that of the Raes threads, proving the relationship between the samples. AMSTAR received the authentic radiocarbon samples from Luigi. Unless he lied again, they are authentic samples. The fact that they show identical compositions to the Raes samples seems to confirm their provenience. Incidentally, I am not a member of AMSTAR, they did not fund my work, and they did not have any control over my methods or conclusions. I also have many fibers from different parts of the Shroud and the Holland cloth that I took with adhesive tape in 1978. I marked them in Turin, and I know they are authentic. The radiocarbon sample can be compared against real fibers from the Shroud as well as real samples from the Holland cloth, which certainly has a known age." ↩ ↩

"The microscopic survey revealed that there were a large variety of fibrils and particulates present in the samples along with occasional assorted "incidental" debris found in limited quanties such as insect parts, pollen, spores, wax, modem synibetic fibrils, red and blue silk, wool, and flair tip pen dye marks (due to a previous investigalor). The red and blue silk fibrils appear to be from backing cloths and borders and are present in almost every sample. This illustrates that there has been transposition of materials from one area of the cloth to another, as it was folded and unfolded numerous times through the ceniuries (as first noted by John Jackson). Therefore, we have arbitrarily set a minimum threshold of 15 specimens of a particular set of characteristics to constitute a class of fibrils and particles typical of a specific location on the cloth." ↩

The last photo is Rudy Dichtl purchasing the infamous “white cotton gloves” that left modern cotton on the surface of the Shroud." ↩

1. "Since 1989, scholars interested in the TS have often requested the raw data from the laboratories, without success (Pourrat 1991). This denial of access led to controversy and hindered the assessment of the analysis performed by the British Museum (Marinelli 2012; Rinaldi 2012). In 2017, several Freedom of Information Act (FOIA) requests to the institutions involved in the TS radiocarbon dating were made. The British Museum replied favourably and made all its files, ‘not dated or arranged in any order’, available. On 18 July 2017, the British Museum electronically sent a file of 211 pages and in September 2017, one of the authors (T.C.) visited the British Museum and scanned more than 500 new pages. ↩

2. "We learned that Zürich performed 4 × 10 measurements for each of their five TS subsamples. Oxford performed five measurements, and while the detailed measurements were not sent to the British Museum, a mean was provided for two measurements, resulting in only three radiocarbon dates. The Arizona report shows that 40 measurements (5 × 8) were made. Several scholars already disclosed the eight Arizona radiocarbon dates (Van Haelst 2002), but these dates have never been confirmed. We are now certain that the eight disclosed dates (designated Arizona raw 2) were correct. However, previously, Arizona modified the errors of two of its eight dates (designated Arizona raw 1)." ↩

1. "In 1982 an unauthorized Carbon-14 dating test was conducted on a single thread from the Raes sample. The experimental thread was provided by Dr. Alan Adler and given to Dr. John Heller. At the time, Adler was unaware that an agreement had been signed by STURP members not to do further testing on Shroud samples. Heller delivered the thread to the California Institute of Technology (CalTech) for dating by world renowned mineralogist Dr. George R. Rossman. Adler informed Rossman that one end of the thread contained, what appeared to be, a “starch contaminate.” Thus, Rossman cut the thread in half and, using what Adler described as Fourier-transform ion cyclotron resonance mass spectrometry (FTMS), dated each end of the thread separately."
   ...
   "Rossman found that the non-contaminated end of the thread dated to 200 AD while the starched end dated to 1200 AD. Although Rossman did not publish these data, Adler had confidence in his capabilities to accurately measure the age of the sample.  Adler stated that Rossman is the “world’s expert in it and there’s no arguing with him . . . if he says these are the dates he got . . .” (10) In a personal conversation with one of the authors (Benford), Rossman confirmed that he was, indeed, the person who carried out the 1982 C-14 testing on the Raes thread provided by Adler." ↩

1. "[A] single weft thread has been extracted at about the midway level of where the Raes sample was removed, beginning about 1 cm medial to the rolled seam that reattached the Shroud to the backing cloth. The space of the missing thread appears to be about 8 cm in length. We do not know the history of this particular thread, but Dr. Alan Adler had a thread about 8 cm in length that came from the Shroud that he acquired in the early 1980s from an unidentified source. He detected what he referred to as starch on one end of this thread. He then had a very unofficial and admittedly inadequate radiocarbon dating done on each end of this thread in 1983. Reportedly, the starched end tested about AD 1000 and the other end of the same thread tested about AD 200. At a minimum, this would indicate that carbon dating the Shroud might be very technically problematic. Assuming that the thread that Dr. Adler had might have been the one that had been extracted at this site, we may have a highly significant, even if inadequate, finding, since the lateral 1 to 2 cm of this thread would have been in the continuation of the area from which the 1988 specimen was extracted. If this scenario is correct, we may not only have evidence that the 1988 sample-extraction-area is abnormal, but we may also have a much more accurate dating of the body of the Shroud, namely, in the range of AD 200." ↩

1. Page 13:  "The irregularities in the spun weft and the thread count have been commented on by observers, especially after the X-rays straddling the two parts of the shroud.  Beginning in the main piece, these irregularities extend into the sidestrip. We can deduce that this was resewn onto the main piece very soon after it had been cut, and in any case while the two lengths were still identical, permitting an almost perfect alignment. That the sidestrip comes from the same original fabric as the main piece can be confirmed by a systematic thread count (at least 20 or so) taken symmetrically from the two pieces of the document." ↩

2. Page 11:  "Some thread counts were taken at different places on the cloth... One can therefore estimate the thread count of the warp to be approximately 38 threads per cm." ↩

1. "Sue took photographs of both the Zurich and uncut C-14 samples to European-trained weaver David Pearson, owner of the French Tailors in Columbus, Ohio. Pearson, who was not told that they were photographs of the Shroud, immediately recognized the disparate weave pattern and differences in thread size, stating "there is no question that there is different material on each side. [i.e. left to right orientation]. […] It is definitely a patch"...  He said that medieval European weavers would typically try to match the original cloth and then hand-stitch approximately ½ inch of new material into the old, such that it was invisible to all but the trained eye. This would ensure the long-term integrity of the material, while maintaining aesthetic consistency throughout the fabric. In addition, this type of detail to repairs would be consistent with the wealth and devotion of the Savoy family, who owned the Shroud at the time.  Sue also sent photos to two other institutions without telling them that they were from the Shroud. A blinded analysis of a photograph of the Zurich C-14 sample, by Thomas Ferguson & Co. Ltd, world-renowned makers of Double Damask Linen, resulted in their perception that the sample was "touched up to prevent unraveling." They further observed, "We have to say that we see the twill pattern clearly on both sides, but still there is something different left versus right." In a third blinded analysis of the Zurich C-14 sample, by Albany International, Louise Harner remarked that “the float is different on either side of the sample. It forms a thick/thin, thick/thin pattern on the right side, whereas the left is much more consistent throughout” (Albany International Research Company, 2000). “Float” is defined as “a length of yarn on the surface of a woven fabric between two consecutive intersections of the yarn with the yarns woven at right angles to it.” ↩

2. "On July 20, 2003, we sent a long, detailed letter by “snail mail.” It was basically the same proposal we had submitted in 2000 when church authorities had asked for them.

1. On page 61 the authors describe a telephone interview conducted with textile expert Gilbert Raes, who had previously cut a sample from the Shroud in 1973 for study.  Raes stated:   "I have compared the specimen which I received in 1973 with Prof Wolfli’s photos. I must state that the general appearance is quite different. What could be the reason for this difference? In each case the main difference lies in the differing number of threads per centimeter in the directions of warp and weft. It is not easy to count the number on a photograph, but I did not find the same number as on the piece I received in 1973. I may conclude from it that the two specimens cannot come from the same item."

1. In response to this assertion by Flury-Lemberg, the authors contacted the president and owner of Without A Trace, Inc. (www.withoutatrace.com) in Chicago, IL, Mr. Michael Ehrlich. Without A Trace has provided invisible mending services for over 20 years. Mr. Ehrlich’s response to Flury-Lemberg’s statement was that the modern-day, time-saving technique for large repairs, called “Inweaving,” would indeed be invisible from the surface but easily recognizable from the back as she claimed. However, the technique used in 16th Century Europe, called “French Weaving,” is an altogether different technique from Inweaving. French Weaving, now only done on small imperfections due to its extensive cost and time, results in both front and back side “invisibility.” According to Mr. Ehrlich, French Weaving involves a tedious thread-by-thread restoration that is undetectable. Mr. Ehrlich further stated that if the 16th Century owners of the Shroud had enough material resources, weeks of time at their disposal, and expert weavers available to them, then they would have, most definitely, used the French Weave for repairs. As will be described later in this paper, the House of Savoy, which was the ruling family in parts of France and Italy, owned the Shroud in the 16th century, and possessed all of these assets. ↩

Lennard, Frances. et. al.  "Tapestry Conservation: Principles and Practice."  2005.From page 8, bottom left:  "Historically, reweaving was not carried out through a support fabric, and was often executed so skillfully that it is not always recognisable as a later addition, although differences in the rate of dye fading have often revealed its presence...  Evidence of reweaving would now usually be left deliberately visible on the reverse of the tapestry by the presence of warp ends and knots."  The use of the word usually implies that sometimes a repair would not be left visible.  The authors point to Figure 1.4, a tapestry from the late 17th to early 18th century where a reweave was not revealed until after some time when new dyes faded at different rate than the original coloring.

1. "But the image on the shroud, which still cannot be duplicated, appears to be a scorch, indicating that the body radiated light and/or heat. It may also have radiated neutrons, which would have irradiated the shroud and changed some of the nuclei to different isotopes by neutron capture." ↩

2. "This flux of neutrons should have other measurable consequences. The neutron irradiation would probably not have been uniform, for example, so the 14C/'C ratio should vary in different parts of the shroud. In addition, other unstable isotopes should have been formed. Several of these isotopes have half-lives long enough that they would still be present, yet short enough that they are not found naturally. The unstable isotopes most likely to be found in the shroud are '"Cl and 41Ca. The presence of either would confirm that the shroud had been irridated with neutrons." ↩
