An Alternate Hypothesis for the Image Color by Raymond N. Rogers [Written 11 September 2001, Published 31 August 2013]

In July 2013, Joe Marino sent me a scan of a paper he and Sue Benford received from Ray Rogers on September 11, 2001. When I reviewed it I realized that, although parts of the paper had been included in several other papers by Ray, as well as in his book, A Chemist's Perspective on the Shroud of Turin, nothing else Rogers wrote included all his observations and thoughts about image color in one dedicated article. So, with Joan Rogers' participation, we proof read and reformatted the paper and replaced the images with higher quality versions, and are making it available here on Shroud.com.

Ariel Agemian Biography by Annig Agemian Raley [15 July 2011]

Without doubt, the painting created by Armenian artist Ariel Agemian and based on the image of the Shroud, is world famous and has become one of the most beloved and iconic portrayals of Jesus of the 20th century. Although the image itself is well known, very few of us know much about the artist himself. I was fortunate to be contacted by his daughter, Annig Agemian Raley, who was kind enough to write a detailed biography of him that she has kindly allowed me to share here with you.

Authentication of the Turin Shroud, The: An Issue in Archaeological Epistemology by William Meacham

Reprinted from the June 1983 edition of CURRENT ANTHROPOLOGY, this article not only makes an interesting argument for the authenticity of the Shroud, circa 1983, but also provides us with excellent insight into the workings of Shroud science. Included after the article itself is a Comments section, with a variety of critiques from many noted Shroud researchers. This includes a rather heated debate by experts on both sides of the authenticity argument, followed by the author's direct and often pointed reply to their comments. However, it provides a great perspective on the nature of Shroud science itself and I am pleased to be able to make it available to you. It is illustrated and includes eleven images. A special word of thanks to the University of Chicago Press for giving me permission to reprint it on this website and Maurizio Marinelli for digitizing the text and images.


Autopsy on the Man of the Shroud, An by Robert Bucklin, M.D., J.D.
Autopsia sobre el Hombre de la Sábana Santa - En Español

This paper was first presented at the May 1997 Nice Symposium in Nice, France, and can also be reached via the "Shroud Conferences & Symposia" page of this website. The author was a world renown forensic pathologist and medical examiner, and formerly Deputy Coronor of Los Angeles, California and Las Vegas, Nevada. He was an avid Shroud researcher for over 50 years and provided a clear and expert medical interpretation of the man depicted on the cloth. In 1978, Dr. Bucklin was a member of STURP, the team that performed the first ever in-depth examination of the Shroud. He died on September 19, 2001. I was very proud that he allowed me to include his important work on this website.

C-14 Debate from the Shroud Newsgroup: alt.turin-shroud - Roger Sparks and William Meacham

This article is compiled from a series of postings that appeared on the Shroud Newsgroup, alt.turin-shroud. In it, Rodger Sparks, a carbon dating expert from New Zealand, and William Meacham, archaeologist and Shroud researcher from Hong Kong, debated some of the theories that have been proposed regarding possible inaccuracies in the 1988 test results. My thanks to them both for their kind permission in allowing me to reprint their comments here on the website.


Chemistry of Autocatalytic Processes in the Context of the Shroud of Turin, The by Ray N. Rogers  (.pdf format) [37k] [October 2002]

This article by Ray Rogers, retired pyrolysis chemist from Los Alamos National Laboratories and original member of the STURP team, is somewhat technical but very important and well worth reading. It discusses the damage to the cloth resulting from the fire of 1532 and concludes that it posed no immediate or ongoing threat to the Shroud. Reportedly, the fear of additional damage to the Shroud by autocatalysis in existing burn and scorch areas prompted the July 2002 restoration.


Chronological History of the Evidence for the Anomalous Nature of the C-14 Sample Area of the Shroud of Turin by Joseph G. Marino and Edwin J. Prior  (.pdf format) [145k] [November 2008]

This excellent summary article is co-authored by noted Shroud scholar Joseph Marino and retired NASA scientist Edwin Prior. It provides compelling, detailed evidence supporting the theory that the 1988 c-14 dating of the Turin Shroud used an anomalous sample not representative of the main Shroud cloth.


EDITOR’S NOTE: Since this article was first written, the authors found considerable additional information to further document the evidence supporting this theory and have compiled it into an Addendum to their original article. You can find the addendum at this link:

Coloured Dissolved Organic Matter (CDOM) contamination, mould damage, biocides and the carbon-14 dating of the Shroud of Turin by Pamela Moon [May 2013]

(Excerpt from Introduction): It is the argument of this paper that the Shroud of Turin was contaminated by water which could be, and most probably was, groundwater, floodwater or bacterially compromised holy water. Coloured dissolved organic matter (CDOM) commonly found in contaminated water sources and the consequences of the introduction of the dissolved matter, could affect the carbon-14 dating.

Concept of Negativity Through the Ages, The vs. The Negative Image on the Shroud by Isabel Piczek

This paper was first presented at the May 1997 Nice Symposium in Nice, France and can also be reached via the "Shroud Conferences & Symposia" page of this website. It gives Isabel Piczek's unique perspective on this important aspect of Shroud research and is profusely illustrated, as all Isabel's presentations are. Isabel is a noted monumental artist and physicist and a well respected Shroud researcher. It may take a few minutes to fully download the article with its many illustrations, but it is well worth the wait.


Concerning the Side Strip on the Shroud of Turin by Alan D. Adler and Alan & Mary Whanger

This paper concludes that the samples used to carbon date the Shroud in 1988 may have been taken from a part of the cloth that was rewoven in medieval times. This paper was first presented at the May 1997 Nice Symposium in Nice, France and can also be reached via the "Shroud Conferences & Symposia" page of this website. It includes three highly magnified x-rays made during the 1978 examination to illustrate its hypothesis. Dr. Adler is an internationally known and well respected Shroud researcher and worked with the late Dr. John Heller in 1979 to complete the chemical analysis that proved the bloodstains on the Shroud were actually blood. He is currently an advisor to the Archbishop of Turin regarding future conservation efforts of the cloth. Alan and Mary Whanger are noted Shroud researchers that have done extensive studies regarding secondary images on the Shroud and were participants in the recently announced discovery of flower images on the cloth.


Conservation of the Shroud of Turin by Alan D. Adler and Larry A. Schwalbe

A realistic evaluation of the conservation problems that must be confronted and resolved in order to preserve the Shroud of Turin and its unique image. Alan Adler, Professor of Chemistry at Western Connecticut State University, is a well known and respected Shroud researcher who worked with the late John Heller in evaluating the blood stains on the Shroud. Both he, and Larry Schwalbe of Los Alamos Laboratories, were original team members of STURP. You will find references to more of their published Shroud papers on the "1978 Scientific Examination" page of this website, in the Bibliography of STURP's Published Papers. This article is reprinted courtesy of Dorothy Crispino, Publisher and Editor of Shroud Spectrum International, the first refereed scientific journal dedicated exclusively to Shroud of Turin research.


Conservation of the Shroud of Turin: Optical Studies, The by Paolo Di Lazzaro, Daniele Murra, Antonino Santoni, Enrico Nichelatti - ENEA Report 2012. [21 January 2013]

Abstract: The ancient linen cloth of the Shroud of Turin is one of the archaeological objects most studied in history, mainly because of the unexplained nature of its image. We have recently irradiated linen fabrics by excimer laser pulses obtaining a Shroud-like coloration, and have recognized photo-chemical processes that may have played a role in the formation of the image embedded into the Shroud. Our results suggest some actions aimed at a long-term conservation of the Shroud and its image.


Consideration to the Uniformity and Effects of the Fabric in the Shroud of Turin by Donna Campbell, M.A., Thomas Ferguson Irish Linen - published by Pam Moon on her Shroud of Turin Exhibition website in September 2014 [5 October 2014]

Pam Moon contacted Thomas Ferguson Irish Linen, a world renowned textile firm (also once employed by Benford and Marino*), and asked them to evaluate the Shroud textile using photographs of the Oxford radiocarbon samples. In her comments regarding mending Campbell concludes, "...there are signs in the Shroud sample that direct the notion of mending or reweaving of the actual woven fabric."


Cotton In Raes/Radiocarbon Threads: The Example of Raes #7 by Thibault Heimburger (.pdf format) [234k], [601k], [417k] [May 2009]

This latest article from Thibault, dedicated to the memory of Sue Benford, is based on his careful analysis of the Raes #7 sample which was provided to him at 2008's Ohio Shroud Conference. His results add further confirmation to the observations and conclusions made by Benford & Marino, Ray Rogers, John Brown, Robert Villarreal and others. As it includes many color photomicrographs, it is broken into three parts to keep the individual files sizes (and consequently, download times) to a minimum. You will find a link at the end of each part of the article that allows you to continue to the next part.


Could the Shroud of Turin be an effect of post-mortem changes? by Lucia Tattoli, Michael Tsokos, Claas Buschmann

This paper was published in the February 2014 issue of Forensic Science, Medicine, and Pathology and bases its theories on an actual forensic case in which a dead body left an imprint on the floor. The authors propose this might be a parallel to the image on the Shroud of Turin. The first two pages of the article can be previewed at the above link but the complete text is behind a pay wall.


Crucifixion of Jesus, The: review of hypothesized mechanisms of death and implications of shock and trauma-induced coagulopathy by Joseph W. Bergeron, M.D. [July 2011]

Debunking The Shroud: Made by Human Hands by Gary Vikan

This article appeared in the November/December 1998 issue of Biblical Archaeology Review and includes a sidebar titled, The Shroud Painting Explained by Walter C. McCrone. The controversial article spawned a wide gamut of responses from the magazine's readers, which were printed in their Letters to the Editor column in a later issue. These are included following the article. A number of other responses were submitted to BAR that were not published, probably due to their length. These included an in-depth collaborative response titled, Deconstructing the "Debunking" of the Shroud, authored by Prof. Dan Scavone, Prof. Karlheinz Dietz, John Markwardt, Mario Latendresse, Rev. Albert Dreisbach, Mark Guscin, Joseph Marino, Emanuela Marinelli and Gino Zaninotto and a separate response titled, Comments on the Radiocarbon Dating of the Turin Shroud by Dr. Stephen Mattingly. These are published here for the first time. Just added is a previously unpublished personal letter from noted Shroud researcher, Dr. Alan Whanger to Mr. Hershel Shanks, Editor of BAR, responding to the Vikan article.


Deep Ultraviolet Radiation Simulates the Turin Shroud Image by Paolo Di Lazzaro, Daniele Murra, Antonino Santoni and Giulio Fanti

Detailed Critical Review of the Chemical Studies on the Turin Shroud, A: Facts and Interpretations by Thibault Heimburger, M.D. (.pdf format) [569k] [January 2008]

This paper offers a detailed synthesis of all the data gathered and the scientific testing performed by John Heller and Alan Adler compared side by side with the analysis performed by Walter McCrone on tape samples taken from the Shroud of Turin in 1978 by the STURP team. It directly addresses the two major questions posed by the researchers: 1) Is the Shroud of Turin a painting? and 2) Is the blood really blood? Thibault's direct comparison includes an evaluation of the effectiveness of the techniques and procedures used for the analysis by all the researchers, their validity for the type of samples being tested, the quality (and credibility) of their respective conclusions and much more. Thibault gets technical, but does so in the simplest and most direct terms. This paper will help the reader fully understand the significance of Heller and Adler's work, recognize the flaws in McCrone's techniques and conclusions and gain a clear, credible, scientific answer to both questions.


Did Geoffroy I de Charny Obtain the Present Turin Shroud on the Smyrna Campaign of 1346 by Prof. Daniel Scavone (.pdf format) [72k] [2005]

In this paper, Dan revisits the theories about the first documented owner of the Shroud, Geoffroy 1 de Charny, and where he might have acquired the relic. In several areas, he disagrees with other Shroud historians on certain aspects of the de Charny theories and makes a valid case for his conclusions.

DNA on the Shroud of Turin: Distinguishing endogenous versus exogenous DNA by Kelly P. Kearse [21 January 2013]

Here is the full Abstract for this paper: "In the late 1990s it was reported that human DNA existed on the Shroud of Turin, and although in a generally degraded state, certain regions were sufficiently intact to clone and sequence three genes from bloodstained fibers: human betaglobin, amelogenin X and amelogenin Y. An unknown variable in such studies is the extent of contamination by exogenous DNA, transferred to the Shroud by persons or objects that have come in contact with cloth. Indeed, the abovementioned genes are not exclusive to blood cells, but are also found within other cell types, including skin cells. Here, a simple experimental approach is described for distinguishing endogenous versus exogenous DNA, which may help establish that DNA in the blood areas of the Shroud of Turin originated from white blood cells (lymphocytes) present on the cloth."


DNA Analysis and the Shroud of Turin: Development of a Shroud CODIS by Kelly P. Kearse [21 January 2014]

This is Kelly's fourth paper on our site and once again, he has taken a very technical subject and made it interesting and understandable for everyone. In this article he clearly explains how the latest refinements in DNA analyses could be applied to the Shroud.


Doubts Concerning the Coins Over the Eyes by Antonio Lombatti

This article originally appeared in the "Letters To The Editor" section of the June/July 1997 issue (#45) of the British Society for the Turin Shroud (BSTS) Newsletter and is available via the "British Society for the Turin Shroud" page of this website. It sparked a lively e-mail debate amongst Shroud researchers, which, through the courtesy of all the participants, is reprinted following the article.

Electronic Archiving and Distribution: The Value of the Internet and CD-ROM Technology  by Barrie M. Schwortz (.pdf format) [22k] (From The 1998 Dallas Meeting of American Sindonology) - Almacenamiento y Distribución Electrónica: El Valor de Internet y de la Tecnología en CD-ROM (En Español)

This presentation started with an overview of the Shroud of Turin Website for those who had never seen it. Using a computer video projector (courtesy of Russell Breault), I was able to project the image directly from my laptop computer to a large screen. I demonstrated many of the website's features, including the use of the "Shroud Library" page to navigate the website. I was also very proud to demonstrate, for the first time ever in public, "The Virtual VP-8" Segment from the Shroud of Turin CD-ROM. This is the most dynamic and interactive portion of the disc, and allows each viewer the opportunity to manipulate the 3-D characteristics of the Shroud image. This moment was made even more exceptional for me when I discovered that Peter Schumacher, an expert on the VP-8 Image Analyzer, was in the room!


Empirical evidence that the blood on the Shroud of Turin is of human origin: Is the current data sufficient? by Kelly P. Kearse [21 January 2013]

Here is an excerpt from the Abstract: "Previous studies have established that the blood areas on the Shroud of Turin consist of real blood and are not composed of artistic pigments. It is commonly reported that the blood is of human origin, but just how substantial is the evidence to support this conclusion? Here, the empirical evidence for the human origin of the Turin Shroud bloodstains is evaluated.... The potential usefulness of additional testing methods, many developed since the original studies were performed approximately thirty years ago, is also discussed."


Evidence for the Shroud in Constantinople prior to 1204 by Daniel C. Scavone  (.pdf format) [32k] (From the 1999 Richmond Conference)

Evidence for the Skewing of the C-14 Dating of the Shroud of Turin Due to Repairs by Joseph G. Marino and M. Sue Benford  (.pdf format) [235k] (From the "Sindone 2000" Orvieto Worldwide Congress) (Includes 8 illustrations)

This article presents carefully documented evidence that the section of the Shroud of Turin from which the 1988 C-14 samples were removed, was in fact, a portion of the cloth that was rewoven and repaired in medieval times. If proven true, this evidence would provide the simplest explanation for the medieval age of the cloth arrived at by the three C-14 laboratories that performed the tests.


Evidence Is Not Proof: A Response to Prof. Timothy Jull by Mark Oxley [21 January 2011]

This article was written in response to a paper titled Investigating a Dated Piece of the Shroud of Turin by the University of Arizona's Rachel Freer-Waters and Prof. Timothy Jull that was published in the December 2010 issue of their peer reviewed journal, Radiocarbon. In part it concluded: "In contrast to other reports on less-documented material, we find no evidence to contradict the idea that the sample studied was taken from the main part of the shroud, as reported by Damon et al. (1989). We also find no evidence for either coatings or dyes, and only minor contaminants."

Mark Oxley's article is a carefully written, clear, concise and thoughtful response to the paper.

Evidences for Testing Hypotheses About the Body Image Formation of the Turin Shroud by Giulio Fanti et al  (.pdf format) [113k] [September 2005] (From the 3rd International Dallas Conference) (24 Co-authors)

This paper, representing the combined efforts of 24 researchers who participate regularly in an online Shroud Science forum, was originally scheduled to be presented at the Dallas Conference, but the authors were notified at the last moment that its acceptance had been revoked because it was deemed to be "too controversial.” Ultimately, it was presented on Saturday evening of the conference by Giulio Fanti to a large group in Dan Porter's Hospitality Suite. However, since the paper was accepted and listed in the Conference Program, I am including it here.


Fathers of American Sindonology, The by Dorothy Crispino

In this fascinating article, Dorothy relates the story of the men who formed the Holy Shroud Guild, the first group to promote Shroud research in the United States. It introduces the men whose efforts ultimately helped STURP obtain permission to perform the 1978 scientific examination of the Shroud. Dorothy was the Publisher and Editor of Shroud Spectrum International, the first peer reviewed journal in the United States dedicated exclusively to the study of the Shroud (Sindonology). This presentation was originally delivered at the 1996 Esopus Conference.

Fire and the Portrait, The by Jack Markwardt - Czech Translation by professional translator Daniela Milton

This paper proposes to resolve, and to reconcile, two of the Shroud's most tantalizing mysteries: When and how did it incur the fire damage now generally referred to as the "poker holes" and when and why was it converted into the portrait known as the Image of Edessa. This paper was originally delivered at the 1998 Turin Symposium.

Editor's Note: See the article on this website titled The Red Stains on the Lier and Other Shroud Copies by Remi Van Haelst. It includes four detailed color photographic closeups of the burn holes discussed in this paper, as well as the transmitted light image of the Shroud mentioned in the footnotes.

Further Studies on the Scorches and the Watermarks by Aldo Guerreschi  (.pdf format) [437k] [September 2005] (From the 3rd International Dallas Conference) (40 photographs and illustrations)

As always, Aldo Guerreschi's thoughtful, thorough and empirical approach to Shroud research is evidenced in this, his latest contribution to our knowledge of the Shroud. In this newest paper, perhaps the best presented at the 2005 Dallas conference, Aldo recreates the fire of 1532 and provides a highly credible explanation for the infamous burn holes and scorches on the Shroud. Long thought to be caused by molten silver dripping onto the cloth from the superheated silver-covered reliquary, this theory was not borne out by the data gathered in 1978 by STURP, as their spectral analysis found no silver residue in any of the burned or scorched areas. Aldo's most recent work provides what may be the best answer to this problem.

Historical Support of a 16th Century Restoration in the Shroud C-14 Sample Area by M. Sue Benford and Joseph G. Marino  (.pdf format) [92k] [August 2002] (Includes 4 illustrations)

One of the main criticisms leveled at Marino and Benford's original proposal was the credibility of their claim that such an "invisible" reweaving method even existed, let alone was good enough to avoid detection by the experts who have studied the Shroud in the last century. Their second paper directly addresses this issue and documents the art of invisible reweaving in great detail.

Image Formation and the Shroud of Turin by Dr. Emily A. Craig and Dr. Randall R. Bresee  (.pdf format) [315k]

This article first appeared in the peer-reviewed Journal of Imaging Science and Technology, Volume 38, No. 1, p.59-67. (1994). It presents a method by which the carbon-dust drawing technique can be modified to produce an image that the authors claim has the same physical characteristics as the image on the Shroud of Turin. The authors are quick to point out that this method and theory do not prove that someone DID produce the image on the Shroud of Turin. They do claim however, that with this method someone actually COULD have created such an image. The original article stresses the concept that a medieval artist could have created the image, but perhaps the most compelling new "twist" to this theory is found in the previously unpublished preface added here by Dr. Craig. Dr. Craig (Kentucky State Medical Examiner's Office) is an internationally recognized expert in forensic anthropology, which includes three-dimensional reconstruction of human faces on skulls as well as the analysis of skeletal trauma and decomposition. Dr. Craig also has over 25 years of experience as a professional medical illustrator with national and international awards for painting, sculpture, and photography. Dr. Bresee is a professor of textile science (University of Tennessee in Knoxville) and an internationally recognized expert in the field of forensic textile analysis.

Imprint, The by Peter Carr (.pdf format) [63k]

This paper provides a fascinating account of the Jospice Mattress imprint. Although this is not directly about the Shroud of Turin, it is still significant in that it is the only scientifically documented case in modern times of a dead body leaving an unexplainable imprint on a piece of cloth. Although the image is different than that on the Shroud, it still provides solid evidence that these type of unexplainable phenomena can occur. You should find it interesting, as the story of the image and the man that left it is well documented.


Inscriptions on the Shroud, The by Mark Guscin (.pdf format) [15k] (Reprinted from the BSTS Newsletter, No. 50, November 1999)

Mark Guscin is a member of both the BSTS and the Centro Español de Sindonologia (CES) and is the noted linguist and historian that wrote the definitive book on the Sudarium of Oviedo. This article challenges the theories of Marion and Courage, two French researchers who claim they have discovered new "inscriptions" on the Shroud.


Investigating a Dated Piece of the Shroud of Turin by Rachel Freer-Waters and Prof. Timothy Jull, Radiocarbon Vol 52, No.4, p. 1521-1527, December 2010

Abstract: We present a photomicrographic investigation of a sample of the Shroud of Turin, split from one used in the radiocarbon dating study of 1988 at Arizona. In contrast to other reports on less-documented material, we find no evidence to contradict the idea that the sample studied was taken from the main part of the shroud, as reported by Damon et al. (1989). We also find no evidence for either coatings or dyes, and only minor contaminants. (Note: This link is to a Subscriber Only page and only the abstract is accessible to the public.

Is The Shroud of Turin a Medieval Photograph? A Critical Examination of the Theory by Barrie M. Schwortz  (.pdf format) [308k] (From the "Sindone 2000" Orvieto Worldwide Congress) (illustrated with 7 photographs)

In this paper the "proto-photography" theory of Nicholas Allen is examined in detail by a professional photographer. Allen proposes that the Shroud image is actually the product of a medieval photographer who used a camera obscura with a crystal lens to "photograph" a corpse onto linen cloth and Allen actually produced such an image using medieval raw materials. In this paper, Allen's results are evaluated in a side-by-side comparison with the image on the Shroud and some of the more sophisticated properties of the Shroud image are explained in detail. A preliminary version of this paper was presented at the May 2000 Imaging Conference in San Felice Circeo, Italy.

Language and Sensibility of Research Papers in Sindonology, The by Agnes Sam  (.pdf format) [33k]

This article discusses the language and semantics used by sindonologists. The author suggests there has been a lack of consistency in the language sindonologists use to describe the 'man' on the Shroud, and consequently, a resulting lack of respect for the spiritual and religious aspects of the image. She recommends the adoption of a style sheet to encourage this consistency and presents her own suggestions to sindonologists for just such a style sheet. Agnes is open to discuss her ideas with interested viewers and encourages scholars to write her directly with their comments. A link to her e-mail address is included at the end of the article.

He compares the image on the Shroud of Turin to the written descriptions of the crucifixion and reaches some interesting conclusions. The article first appeared in the January 1970 edition of Medicine, Science and the Law.


The Lier Shroud and Lucas Cranach the Elder by Pam Moon

Recently published on Pam's Shroud of Turin Exhibition website [7 June 2014]. "This paper argues that the artist who created the Shroud of Turin copy known as the Lier (or Lierre) Shroud may be Lucas Cranach the Elder (1472-1553)... It examines the signature on the Shroud and compares it with the different ways Cranach signed his name."


Life-size Reproduction of the Shroud of Turin and its Image by Luigi Garlaschelli

This paper was published in the Journal of Imaging Science and Technology, July/August 2010, Volume 54, Issue 4, pp. 040301-(14) (Abstract Only).

Editor's Note: In October 2009, in response to a major media release by Professor Garlachelli claiming he had "reproduced" the Shroud image, I wrote and published an editorial titled Science By Press Release? In it I was critical of the fact that scientific claims are rarely if ever released to a major media outlet BEFORE being published in the peer-reviewed scientific literature, as was the case with Professor Garlaschelli's work. His original press release stated that the article would be published in such a journal "next week" Now, almost a year later, his work has finally been published in the above journal. You might also wish to read Comments About the Recent Experiment of Professor Luigi Garlaschelli by Thibault Heimburger. For this article, Thibault consulted directly with Professor Garlaschelli and provides a detailed overview of his techniques, along with a point by point comparison between Garlaschelli's results and the image on the Shroud (November 2009) (Full Paper Available).


Man Of The Shroud Was Washed, The by Frederick T. Zugibe, M.D., Ph.D.

This paper provides a scientific basis for the hypothesis that the Man of the Shroud had been washed prior to placement on the Shroud. Dr. Zugibe is a professor of anatomy and the Senior Medical Examiner of Rockland County, New York. His studies are based on the analysis of antemortem and postmortem blood flow patterns on cadavers and their comparison to those on the Shroud. A number of relevant facets of scripture and Jewish customs are also discussed. This article first appeared in Sindon N. S. in 1989. Three somewhat graphic photographs accompany the article. Parental Discretion Advised.

Microscopical Investigation of Selected Raes Threads from the Shroud of Turin by John L. Brown  (.pdf format) [190k] [January 2005]

John L. Brown was the Principal Research Scientist at the Georgia Tech Research Institute's Energy and Materials Sciences Laboratory at the Georgia Institute of Technology until his retirement in 1984. He is an expert microscopist specializing in the field of forensic analysis of material failures, and was enlisted by Ray Rogers to examine samples of selected Raes threads taken from the Shroud in 1973. These threads are important because they were taken from the area immediately adjoining the sample used for carbon 14 analysis of the Shroud in 1988. In this article, John provides an independent review of the samples he examined, along with seven previously unpublished photomicrographs and scanning electron microscope views that supplement and support the conclusions drawn by Ray in his recent peer reviewed paper, "Studies on the radiocarbon sample from the Shroud of Turin," Thermochimica Acta Vol. 425, Issues 1-2, 20 January 2005, Pages 189-194.

The Missing Corners and the Radiocarbon date of the Shroud of Turin by Pam Moon

Recently published on Pam's Shroud of Turin Exhibition website [7 June 2014]. "This paper looks at the mystery of the missing corners on the Shroud of Turin. Two corners were removed at some time and two are intact... This paper argues that the corners were removed because of water damage from douse water used to put out the fire that partially burned the Shroud in 1532. The contaminated douse water led to the formation of mould and bacteria on the cloth."

Natural Factors Affecting the Apparent Radiocarbon Age of Textiles by Mario Moroni and Remi van Haelst

The authors present a series of experiments and a statistical analysis of the Carbon dating that concludes "the C14 content may not be the same over the whole surface of the Shroud" and that "a single radiocarbon dating result... cannot be regarded as conclusive evidence for a mediaeval date for the Shroud of Turin." This article originally appeared in Shroud News No. 100 (February 1997). Remi van Haelst also presented another paper titled "The Lier Shroud" at the May 1997 Nice Symposium.


Natural Textile Fibres - Optical Activity, Racemization and Epimerization by Dr. Silvio Diana and Prof. Emanuela Marinelli Paolicchi

New Radiocarbon Hypothesis by John Jackson, A by John Jackson  (.pdf format) [11k] [May 2008]

David Rolfe's 2008 BBC documentary features physicist John Jackson, co-founder of the 1978 STURP team and founder of the Turin Shroud Center of Colorado, and discusses his new hypothesis regarding the 1988 radiocarbon dating of the Shroud, based on possible c14 enrichment of linen due to the CO (carbon monoxide) in the atmosphere. According to Jackson, a 2% contamination could skew the resulting date by as much as 1400 years. Rather than attempt to describe Jackson's theory myself, I asked John to write a short article to describe it in his own words.

Pattern recognition after image processing of low-contrast images, the case of the Shroud of Turin by Paolo Di Lazzaro, Daniele Murra and Barrie Schwortz - Journal: Pattern Recognition, available online December 31, 2012.

Abstract: We discuss the potentially misleading effect of software techniques for elaborating low-contrast images. In particular, we present the example of the stains embedded into one of the most studied archaeological objects in history, the Shroud of Turin. We show for the first time that image processing of both old and recent photographs of the Shroud may lead some researchers to perceive inscriptions and patterns that do not actually exist, confirming that there is a narrow boundary between image enhancement and manipulation.

CAUTION: The subject of this paper is crucifixion and it contains graphic illustrations. PARENTAL DISCRETION IS ADVISED.


Point of Nuclear Physics About the Shroud of Turin, A by Gildas Rouvillois

In this short article, the author disagrees with the tentative explanation of the controversial carbon dating of the Shroud by J.B.Rinaudo. Rinaudo surmised that simultaneous fluxes of protons and neutrons could explain both the image on the cloth (by the protons) and the 13-century slip of time of the carbon14 nuclei (by the neutrons).

Professional Arts and the Principle and Practice of Conservation, The - Restoration Versus the Turin Shroud by Isabel Piczek

In this paper the author expresses her concerns as a professional artist over future conservation plans for the Shroud and demonstrates why regarding the image as a painting will have serious impact on its preservation. This paper was originally presented at the 1998 Turin Symposium.


Gli scatti proibiti della Sindone (The Prohibited Photographs of the Shroud) - La Stampa 12 September 2013

This is an Italian language article published on September 12, 2013 in the newspaper La Stampa that reported that new evidence reveals an unauthorized series of photographs was made of the Shroud the night before Secondo Pia made the first official photographs in 1898! I expect we will be hearing more about this in the future. Here is a Google translation of the opening paragraphs:

The first official photos taken in the Cathedral of the Holy Shroud of Turin by Secondo Pia May 28, 1898, after two tests made May 25, were preceded by a series of illegal shots, so far unknown, made by an unauthorized photographer, A. Gallo, who acted the night before on 27 May and developed his plates on 1 June. This was announced by the Museum of the Holy Shroud, directed by Gian Maria Zaccone, who has received the gift of the photographs from the descendants of Gallo, the family Beltramo Ceppi of Milan.


Proposal for High Resolution Colorimetric Mapping of the Turin Shroud, A: Analysis of Metrological Problems by Giulio Fanti

The author is a professor in the Department of Mechanical Engineering at the University of Padua in Italy. Included here is the paper he presented at the Nice (France) Symposium in May of 1997. It proposes the use of high resolution digital colorimetric mapping of the Shroud to create a database that could be used for further scientific analyses and possibly lead to a better understanding of the image formation mechanism . In the article, which includes six illustrations, he describes the experiment and apparatus, discusses some of the problem areas that might be encountered and suggests possible solutions.


Prospects of Research of the Turin Shroud in Russia by Alexander Belyakov

The author is an orthodox physicist and graduate of Moscow University who is currently director of the Moscow Center of the Turin Shroud. Included here is the text of his presentation made at the Shroud conference in San Felice, Italy, on August 24-25, 1996. In it he discusses how changing ideologies have opened the door to Shroud research in Russia. He then presents his theories on the image formation mechanism of the Shroud. Also included at the end of the article is the text of another short presentation he made that discusses the reversed perspective rule in Orthodox iconography and its "genealogical" linkage of the Shroud of Turin to the Orthodox Mandylion.


Pyrolysis/Mass Spectrometry Applied to the Shroud of Turin by Ray Rogers

A technical paper from Ray Rogers that explains how Pyrolysis/Mass Spectrometry was used to detect impurities (like painting mediums) on samples of the Shroud of Turin. Interestingly, a gum coating was found on the fibers of the Raes Sample, a section cut from the Shroud in 1973 from an area directly adjoining the 1988 c14 sample. However, this gum coating was not found on any fibers from anywhere else on the Shroud. The tests provided quantitative evidence that the Raes sample and consequently, the adjoining 1988 c14 sample, were both anomalous and different from the rest of the Shroud. With this, and a significant amount of other corroborative scientific evidence, the validity of the 1988 c14 dating of the Shroud is even further in doubt.


Radiocarbon Dating of the Shroud of Turin, by P. E. Damon, D. J. Donahue, B. H. Gore, A. L. Hatheway, A. J. T. Jull, T. W. Linick, P. J. Sercel, L. J. Toolin, C.R. Bronk, E. T. Hall, R. E. M. Hedges, R. Housley, I. A. Law, C. Perry, G. Bonani, S. Trumbore, W. Woelfli, J. C. Ambers, S. G. E. Bowman, M. N. Leese & M. S. Tite.

This is the paper, reprinted from "Nature," the weekly journal in which it first appeared in February 1989, that concluded the Shroud is of medieval origin and dated the cloth to around 1325 A.D. It has had more impact on Shroud research than any other paper ever written on the subject. When first released, it was given considerable publicity and much of the world accepted its conclusions, virtually bringing all other Shroud research to a halt. In the last few years however, new evidence has suggested the possibility that a contaminant, in the form of a bioplastic coating, might have caused a skewing of the resultant date. Others have criticized the protocol followed by the laboratories, which was changed at the last minute from the one recommended by a panel of experts. Critically absent, according to several researchers, was any chemical analysis of the samples prior to testing. This has led a number of scientists to challenge the conclusions of the paper, which claims a "95% certainty" for the results. They point out that in biochemistry, total chemical analysis of a biological product is the first thing done to assure the reader that you have what you think you have. Anything less than that must be regarded as a preliminary characterization and should be so stated. They also point out that "Nature" is not a peer-reviewed journal. This is the first time the paper has ever appeared on the Internet. Considering the number of articles critical of the paper found on this website, I am pleased to give everyone an opportunity to finally read the actual paper for themselves. I am grateful to "Nature" for allowing me to reprint it and to Mr. Timothy Jull, of the University of Arizona, for providing me with an excellent copy and helping me get permission to include it here. I consider it an important addition to this website.

Editor's Note: I recently received a note from Mr. Jull in which he made the following comments:

"I looked at the Shroud website recently and noted the addition of the Nature article. I noted some of the editorial remarks - I have a comment on one at this time. It is TOTALLY INCORRECT to state that Nature is not a peer-reviewed journal (I realize your comments attribute this remark to others...). This is not true. All papers for Nature are reviewed in the normal way for scientific publications. You can confirm from the editors of Nature this is correct. I think you should note this assertion is wrong on your web page. Otherwise, I find your site very interesting."


Radiocarbon Dating The Shroud of Turin - A Critical Statistical Analysis by Remi Van Haelst

First published after the release of the radiocarbon dating of the Shroud in 1988, this was one of the first papers to scientifically refute the claimed 95% confidence for the mediaeval age of the cloth. I should point out that this is a very technical paper and may be somewhat difficult for some viewers to understand. This is an updated version done in 1997.


Radiocarbon Dating The Shroud of Turin - The Nature Report by Remi Van Haelst (.pdf format) [94k]

The author's newly updated response that scientifically refutes the 1989 carbon dating article that appeared in the weekly journal "Nature." Remi's articles are usually quite technical, and this one is no exception. For experts.


Radiocarbon Measurement and the Age of the Turin Shroud: Possibilities and Uncertainties by William Meacham

This is one of the first published scientific papers that dealt with carbon dating the Shroud of Turin. It was presented by William Meacham, a noted archaeologist, at the 1986 Shroud Symposium in Hong Kong. In it, the author expresses his concerns that "contamination is a very serious problem in interpreting the results of radiocarbon measurement," and examines the issue of the reliability of C-14 testing to produce an 'absolute date' on the Shroud. Meacham took part in the Turin Workshop in late September 1986 at which the carbon dating protocol was determined, but was ultimately excluded from any further involvement in the dating of the Turin Shroud.

Red Stains on the Lier and Other Shroud Copies, The by Remi Van Haelst

Remi Van Haelst is a researcher from Belgium and is also a member of CIELT, the group that sponsored the May 1997 Nice Symposium where this paper was first presented. His paper discusses many of the known Shroud replicas and copies and compares them to the original. He also discusses the four sets of "L shaped" burn holes in the Shroud that probably predate the 1532 fire. The article includes four detailed color photographic closeups of the burn holes as well as a transmitted light image of the Shroud. Since Remi used several of my photographs for his research, I have taken the liberty of annotating certain portions of the text and adding a graphic to the article for further clarity.


Report on the Czechia Shroud Copy by Dr. Leo Bazant-Hegemark

Dr. Leo Bazant-Hegemark, a Shroud researcher in Austria, recently made a field trip to Czechia to examine the previously unknown Shroud copy discovered there in January 1999. Dr. Bazant was kind enough to send me a letter with details from his trip journal, along with a number of photographs of the hand painted cloth. A letter of authenticity signed by the Archbishop of Turin was also found with the copy, which was originally made in 1651. I have included excerpts from Dr. Bazant's letter (along with five color photographs), in this informal article. My sincere thanks to Dr. Bazant for his kindness in sharing this information with us.

Shroud in the News for Christmas 2011, The - An Editorial Response by Barrie Schwortz [January 21, 2012]

Editorial response addressing the many Shroud stories that permeated the news just before Christmas 2011.


Shroud-like Coloration of Linen by Nanosecond Laser Pulses in the Vacuum Ultraviolet by P. Di Lazzaro, D. Murra, E. Nichelatti, A. Santoni, G. Baldacchini - ENEA Report. A similar paper by the same authors also appeared in the peer reviewed journal Applied Optics, Vol. 51, Issue 36, pp. 8567-8578 (2012), titled Superficial and Shroud-like coloration of linen by short laser pulses in the vacuum ultraviolet. [21 January 2013]

Abstract: We present a survey on five-years experiments of excimer laser irradiation of linen fabrics, seeking for a coloration mechanism able to reproduce the microscopic complexity of the body image embedded onto the Shroud of Turin. We achieved a superficial Shroud-like coloration in a narrow range of irradiation parameters. We also obtained latent coloration that appears after artificial or natural aging of linen following laser irradiations that at first did not generate any visible effect. Most importantly, we have recognized distinct photo-chemical processes that account for both coloration and latent coloration. These processes may have played a role in the generation of the body image on the Shroud of Turin.


Shroud "Make Over", The: Science or Marketing? by Bruno Barberis

On October 6, 2009, Italian Prof. Luigi Garlaschelli issued a press release to the Reuters News Service, announcing he had "reproduced" the Shroud image using medieval technologies, thus proving it a fake.

The Shroud of Turin - A Critical Assessment by Atle Ottesen Søvik

This article is a translation of the article “Likkledet i Torino – en kritisk vurdering," published in Teologisk Tidsskrift (Journal of Theology), no 3, 2013: 266-294 [7 June 2014] - This article discusses the question of whether the Shroud of Turin is the real burial cloth of Jesus, and it consists of four parts. First I present facts about the Shroud. Then I discuss whether the image comes from a corpse or is artificially produced another way, and conclude that it comes from a corpse. This means that if it is a forgery, a corpse was used to create the image. After that, I briefly discuss whether it may be the burial cloth of an unknown crucified man, and argue that it must be the burial cloth of Jesus or a forgery meant to resemble Jesus. Finally, I discuss the crucial question of when the image was formed: is it a forgery from the fourteenth century or is it the real burial cloth of Jesus from AD 30?

Shroud of Turin, The: An Amino-Carbonyl Reaction (Maillard Reaction) May Explain The Image Formation by Raymond N. Rogers and Anna Arnoldi  (.pdf format) [196k] [July 2004] (Includes 4 color illustrations).

This paper originally appeared in Melanoidins vol. 4, Ames J.M. ed., Office for Official Publications of the European Communities, Luxembourg, 2003, pp.106-113. The paper demonstrates that a complex but well documented, naturally occurring chemical reaction may explain all of the known image chemistry of the Shroud of Turin and provide us with an important clue in determining the actual image formation mechanism. Ray's work is detailed and scientific and necessarily, quite technical in nature. Even if you don't have a degree in chemistry, the points he makes are quite understandable, the papers are well researched and well written and the conclusions are very clear.


Shroud of Turin and Its Radiodating, The by Maria-Grazia Siliato from the 1993 Rome Shroud Symposium - Translation by Dr. Augusto Monacelli [5 October 2014]

This paper was originally presented at the 1993 Rome Shroud Symposium, long before Benford and Marino conducted their research. In it, Siliato discusses evidence of repairs and extraneous woven materials detected in Shroud samples and states, among other things, "It was manipulated many times for mending and restoration works."


Shroud of Turin, The: Genuine Artifact or Manufactured Relic? by Jack Kilmon

This is a link to an article that appeared in "The Glyph," the Journal of the Archaeological Institute of America (San Diego). Mr. Kilmon argues in favor of authenticity and offers a comprehensive review of the scientific facts about the Shroud, siting references for many of them. The article includes closeup photographs of the Shroud and an illustration of the entombed and enshrouded Jesus of Nazareth found in a prayer book from Budapest known as the Pray Manuscript. Kilmon states, "The illustration not only depicts the unique "L" pattern of burn holes but also the unique weave pattern of the shroud. There can be no mistake that the Pray Manuscript of 1192 was modeled from the Shroud of Turin."


Shroud of Turin, The: A Historiographical Approach by Tristian Casabianca (Abstract Only) [May 2013]

Criteria of historical assessment are applied to the Turin Shroud to determine which hypothesis relating to the image formation process is the most likely. To implement this, a ‘Minimal Facts’ approach is followed that takes into account only physicochemical and historical data receiving the widest consensus among contemporary scientists.

In the last months of his life, Ray was able to obtain a new source for irradiating linen with various types of radiation. Using this source, he performed a series of experiments and observations and wrote this final article detailing his conclusions regarding radiation as an image formation mechanism on the Shroud. It includes 12 color and b&w photomicrographs.


Sight and brain: an introduction to the visually misleading images by Daniele Murra [May 2010] (From the Proceedings of the 2010 Frascati Conference)

This paper clearly explains how the limits of human visual perception come into play when studying the image(s) on the Shroud of Turin. I consider it a must read for any serious Shroud scholar.


Some Details About the STURP Quad Mosaic Images by Barrie Schwortz [May 2013]

This article was originally written in 2003 and was made available only to the online Shroud Science Group. Ray Rogers had pointed out in a posting to the group that this image is another important piece of scientific evidence supporting the belief that the area sampled for the C14 dating in 1988 was anomalous. I wrote the article with the assistance of Jean Lorre, original STURP imaging team member from the Jet Propulsion Laboratory, who had performed the image processing. I updated it in 2011 since the topic of the STURP Quad Mosaic images continues to be discussed and debated.

Studies on the Radiocarbon Sample from the Shroud of Turin by Raymond N. Rogers [January 2005] (Full Paper) [Sept 2010]
Studies on the Radiocarbon Sample from the Shroud of Turin by Raymond N. Rogers [January 2005] (Abstract Only)

This is a link to Ray's final peer reviewed paper on the Shroud in Thermochimica Acta . It was published on January 20, 2005, only five weeks before his death. In it, Ray proved that the sample used for the radiocarbon dating of the Shroud in 1988 was anomalous. This is probably the most important research paper Ray ever published on the Shroud and is arguably, the most important scientific paper published on the Shroud in last 18 years period. It is the first peer reviewed science to openly challenge the radiocarbon dating of 1988.

Remi's articles are usually quite technical, and this one is no exception. For experts.


O Sudário de Turim: Entre a história da arte e a Datação do Carbono 14 (The Shroud of Turin: Between Art History and Carbon 14 Dating) by by Antônio Jackson de Souza Brandão

This link is to the complete paper (in pdf format) of a Portuguese language article published in the online Brazilian journal Lumen et Virtus, nº 10, vol. v, March 2014. Here is a synopsis: When published in 1989, the test results of carbon 14 of the Turin Shroud, led many scientists, agnostics and theists of various religious associations to celebrate their results on the "unmasking" of the strange relic. They forgot, however, that the history of art, documented for centuries, demonstrates exactly the opposite, its imagery making inconceivable [dates] between 1260 to 1390, a period appointed as its probable creation.


Sudarium of Oviedo, The by Mark Guscin

This paper discusses in detail the Sudarium, a bloodstained cloth from Oviedo, Spain that some believe is the "face cloth" that wrapped the head of Jesus in the tomb. It was first presented at the Nice Symposium in May 1997 and can also be accessed via the "Shroud Conferences & Symposia" page of this site. Mark is a member of CIELT, the French organization that sponsored the symposium, as well as a member of the Centro España de Sindonología, the organization directly responsible for research on the sudarium. This fascinating paper describes the sudarium in detail and explains its relationship to the Shroud of Turin. It includes five color photographs.


Sudarium of Oviedo, The: A Study of Fiber Structures by Raymond N. Rogers  (.pdf format) [219k] [Written 2004, Published 2008] (Includes 7 color photomicrographs)

This paper was originally written in 2004, when Ray Rogers examined linen fiber samples from the Sudarium of Oviedo at the request of the Oviedo authorities. He submitted this paper to them for their approval, which they gave, and Ray planned to ultimately have it published on this website. Sadly, he set it aside for other Shroud research and it almost was lost after his death, but thanks to Joanna Emery, noted Shroud author who discovered its existence during her correspondence with the Oviedo authorities, it was "found" again and read (by Joanna) at the August 2008 Ohio Shroud Conference. I am pleased to finally be able to include it here.


Summarizing a Set of Radiocarbon Determinations: A Robust Approach by Dr J.A. Christen

This paper was published in Applied Statistics, Vol. 43, No. 3. (1994), pp. 489-503, in 1994 and corroborates the findings of the 1988 radiocarbon dating of the Shroud. The above link takes you to a page where one can only read the Abstract and Introduction. The Shroud-related section of the article (Example 2 page 498), is only available by purchasing the entire article.

In my May 2008 correspondence with Dr. Christen, he made the following statement regarding the article:

You could include my paper in your list as an early analysis before the origin of the samples themselves were questioned.

Yes, my analysis corroborates the results of the 1988 dating, but this is only conditional of the fact that the dated material was indeed part of the Shroud. This latter fact is now disputed, as I understand. I don't think there is any substantial error in the c14 dating and its subsequent analysis, but apparently the samples did not belong to the Shroud itself. The C14 labs had no chance whatsoever.

The Turin Shroud Body Image: The Scorch Hypothesis Revisited by Thibault Heimburger [21 January 2013]

In recent months, the rather dated Scorch Hypothesis of image formation has found some new and rather vocal supporters on the Shroud blogs. This excellent article by noted Shroud researcher Thibault Heimburger reviews the known data, details his latest experiments and presents his newest evidence (including many color photographs) that challenges this hypothesis in great detail. It was originally posted on Dan Porter's blog in October 2012. Here is an excerpt from Thibault's conclusions: "The TS image is not a scorch, even a light scorch. In fact, this old hypothesis is very easy to rule out definitively as the body image formation mechanism with some basic experiments and a microscope." Make sure to read Thibault's follow up article published in April 2014 titled, The Scorch Hypothesis: New Experiments.

This is an in-depth article with complete text and illustrations. Dr. Allen, who concludes that the Shroud is an actual photograph produced using 13th century technology, is the author of a soon to be released book on the subject. He appeared recently in a BBC television program where he demonstrated his theories and results. This is one of a number of Shroud-related articles on Dr. Allen's website.

Walter C. McCrone and the Max Frei Sticky Tapes of 1978: A Background Study by Paul C. Maloney

This article encapsulates and updates the much more extensive paper Paul originally presented at the 1999 Richmond Shroud Conference titled, History of Botanical Research on the Shroud of Turin. [Editor's Note: That paper is currently not available online but was published in the Proceedings of the 1999 Shroud of Turin International Research Conference - Richmond, Virginia - WALSH, Bryan J. (Ed.) - Magisterium Press, Glen Allen, Virginia (USA) 2000].


Was The Shroud In Languedoc During The Missing Years? by Jack Markwardt

This paper presents an interesting historical hypothesis. It was first presented at the May 1997 Nice Symposium in Nice, France and can also be reached via the "Shroud Conferences & Symposia" page of this website. It focuses upon the "Missing Years" in the history of the Shroud of Turin, presents a hypothetical reconstruction of several of the more mysterious chapters in the cloth's biography, and suggests that the sindonic path between Constantinople and Lirey runs directly through Languedoc.
