How Old is the ‘Shroud’?

By J. Douglas Kenyon

Brought to Europe, it is believed, during the Crusades, the Shroud of Turin, Italy has been an object of veneration among the faithful ever since. Measuring 4.4 by 1.2 meters, the famous burial garment, alluded to in the New Testament, bears the subtle reversed image of a crucified man. The image, say believers, was burned into the cloth at the moment of resurrection. Whether or not that view is correct, most scientists, at least agree that, while they do not know how the image was made, it is clear that it could not have been painted or printed.

But, is the Shroud actually old enough to be direct physical evidence for—as many Christians believe—the historical death and resurrection of Jesus Christ…or not…?


Alas, in 1988, radiocarbon tests, made by laboratories in Oxford, UK; Zurich, Switzerland; and Tucson, Arizona, yielded a date of: from AD 1260 to 1390. That study was published in the journal Nature. Skeptics immediately trumpeted that the Shroud had thus been proved a medieval fraud, possibly made to boost the lucrative pilgrimage business. At that point, many believed, the long-running debate over the authenticity of the Shroud of Turin had finally been put to rest. Over 40 years later, however, the Shroud doesn’t yet appear ready to ‘rest’ from the flames of controversy.


Indeed, a new 2022 study by respected Italian scientist Liberato DeCaro, utilizing a revolutionary technique called “Wide-Angle X-Scattering” (WAXS) now declares definitively, the Shroud is at least 2,000 years old (https://www.mdpi.com/2571-9408/5/2/47). And this is not the first time that serious doubt has been cast upon the 1988 report. At least one of the scholars who participated in that study publicly conceded a big mistake had been made and that the Shroud is old enough to have been what it is advertised to be.


In a video recording made shortly before he died of cancer in 2005, and shown later on the Discovery Channel, Dr. Raymond Rogers revealed that the part of the shroud used for carbon-14 tests was actually dyed cotton, skillfully ‘rewoven’ into the original linen to repair a damaged section. Rogers said that indeed his own tests showed the Shroud is much older, dating to between 1,300 and three thousand years ago. Rogers had initially argued, following the 1988 study, that the cloth was a medieval hoax—an assertion for which he repented in his Discovery Channel video.
To obtain carbon for measurement, the dating of any artifact requires taking a small sample which is ultimately burned and destroyed. The amount of carbon 14 still present, decaying at a known rate, gives a reliable indicator of an object’s age. The need to destroy part of an artifact, though, has always been a strong arguments against such dating, and has inspired interest in alternative, non-destructive, testing.


In 2019 Rogers’ conclusions were corroborated by a French-Italian study (https://onlinelibrary.wiley.com/doi/full/10.1111/arcm.12467) after a Freedom-of-Information-Act (FOIA)-requested examination of the raw data used in the 1988 test and kept at the British Museum. The conclusion was, that since only pieces from the edges of the cloth had been tested, the dating was unreliable.


Another mystery in Shroud history has to do with its possible connection to the secretive chivalric order of the Knights Templar. Paleographer Barbara Frale, a long-time research scholar in the Vatican’s secret archives, and an authority on the Templars, found evidence that, during the thirteenth century—a time when most historians had been unable to account for its whereabouts—the Shroud was secretly kept and venerated by the Knights Templar (The Templars: The Secret History Revealed). It had disappeared from history during the sack of Constantinople in 1204, not to reappear until the middle of the fourteenth century. But, according to Frale, a young Frenchman Arnaut Sabbatier who entered the order in 1287, testified to being shown a linen cloth on which appeared the figure of a crucified man, and being told to venerate the image by kissing the feet three times.


Previously Frale had made headlines with her discovery in the Vatican library of the Chinon Parchment, a document revealing that Pope Clement V did not condemn the Templars for heresy as had been believed for centuries. Like the Dan Brown novel and movie, The Da Vinci Code, Frale suggested a hitherto unsuspected behind-the-scenes role in church history for the Templars, and a special significance for the Shroud in conferring religious legitimacy. There are some who believe the Shroud might, in fact, be the ‘Holy Grail,’ long reputed to be in Templar custody.


The catholic church has taken no position on the Shroud’s authenticity but, nevertheless, continues to guard it very carefully, rarely permitting public showings. It was last displayed in 2,015 and is not scheduled to be seen again until 2025.

The Trials of the Shroud

X Ray Show Turin Shroud 2000 Years Old

The Shroud of Turin is arguably the most important relic of Christianity. According to tradition, it is the sepulchral sheet that would have wrapped the body of Jesus after the crucifixion. In 1988 the carbon 14 dating of some samples taken from the Shroud, carried out by three distinct laboratories, indicated that it should have only about 7 centuries of history, all in Europe. Therefore, the sheet would be inauthentic since, apparently, it dates back only to the Middle Ages. Now, in a new peer-reviewed study “X-ray Dating of a Turin Shroud’s Linen Sample” published in March 2022, by MDPI Heritage (https://www.mdpi.com/2571-9408/5/2/47), Italian scientist Liberato De Caro has reported that fabric tests show the Shroud is indeed 2,000 years old. De Caro and his colleagues made the discovery by utilizing a technique called “Wide-Angle X-ray Scattering” (WAXS). With such an analysis, it is possible, they say, to evaluate the structural degradation due to natural aging of the cellulose that makes up the fibers of the linen threads.


Textile samples, says the study, are especially vulnerable to contamination of all kinds, which are not always possible to control and to completely remove from the artifact to be dated. Molds and bacteria, colonizing textile fibers, and dirt or carbon-containing minerals, such as limestone, in the empty spaces between fibers represent about 50% of the volume, that at a microscopic level, can be difficult to completely eliminate in the sample cleaning phase. All of that can distort the dating. In fact, the fabric can include new carbon 14, assimilated through epochs subsequent to the one in which the textile originated. Textile samples indeed are the most at risk of contamination for radio dating, and are difficult to eliminate, since the surface per unit of weight exposed to the interaction with the outside is very high, due to the small diameter of the microfibers (10-20 micrometers) and the high number of microfibers per thread (about 200). About half the volume of a natural fiber yarn is actually empty, interstitial space, filled with air or anything else, between the fibers that compose it. Everything that enters the fibers must be carefully removed. If this does not happen, carbon 14 dating is not reliable.


It cannot be ruled out that such a thing could have happened in the 1988 study, a fact confirmed by the fact that moving from the periphery towards the center of the sheet, along the longer side, there is a significant increase in carbon 14. In this way, it is possible to date with X-ray analysis the ancient tissues from which the samples were taken. Starting from the results obtained in the 1988 study, on comparative samples taken from linen fabrics of varying age between 3000 BC and 2000 AD, it was possible to date a sample of the Shroud thread. According to the De Caro study, the Shroud sample analyzed consists of a wire taken near the 1988 / radiocarbon area (angle corresponding to the foot area of the frontal image, near the so-called Raes sample). The size of the linen sample analyzed is approximately 0.5 mm × 1 mm. The integrated WAXS data profiles, obtained on the Shroud sample (orange curve in the figure), are compatible with the similar measurements obtained on a linen sample whose dating, according to historical documents, is 55-74 AD, siege of Masada, Israel (green curve in the figure). The degree of natural aging of the cellulose that constitutes the linen of the investigated sample, obtained by X-ray analysis, showed that the Shroud fabric is much older than the 7 centuries proposed by the radiocarbon dating of 1988.
