A Summary of STURP's Conclusions
Editor's Note: After years of exhaustive study and evaluation of the data and the submission of their research to highly regarded peer-reviewed scientific journals, the following official Summary of STURP's Conclusions was written by John Heller (in non-technical language) and distributed at the press conference held after STURP's final meeting in October 1981:
No pigments, paints, dyes or stains have been found on the fibrils. X-ray, fluorescence and microchemistry on the fibrils preclude the possibility of paint being used as a method for creating the image. Ultra Violet and infrared evaluation confirm these studies. Computer image enhancement and analysis by a device known as a VP-8 image analyzer show that the image has unique, three-dimensional information encoded in it. Microchemical evaluation has indicated no evidence of any spices, oils, or any biochemicals known to be produced by the body in life or in death. It is clear that there has been a direct contact of the Shroud with a body, which explains certain features such as scourge marks, as well as the blood. However, while this type of contact might explain some of the features of the torso, it is totally incapable of explaining the image of the face with the high resolution that has been amply demonstrated by photography.
The basic problem from a scientific point of view is that some explanations which might be tenable from a chemical point of view, are precluded by physics. Contrariwise, certain physical explanations which may be attractive are completely precluded by the chemistry. For an adequate explanation for the image of the Shroud, one must have an explanation which is scientifically sound, from a physical, chemical, biological and medical viewpoint. At the present, this type of solution does not appear to be obtainable by the best efforts of the members of the Shroud Team. Furthermore, experiments in physics and chemistry with old linen have failed to reproduce adequately the phenomenon presented by the Shroud of Turin. The scientific consensus is that the image was produced by something which resulted in oxidation, dehydration and conjugation of the polysaccharide structure of the microfibrils of the linen itself. Such changes can be duplicated in the laboratory by certain chemical and physical processes. A similar type of change in linen can be obtained by sulfuric acid or heat. However, there are no chemical or physical methods known which can account for the totality of the image, nor can any combination of physical, chemical, biological or medical circumstances explain the image adequately.
Thus, the answer to the question of how the image was produced or what produced the image remains, now, as it has in the past, a mystery.
We can conclude for now that the Shroud image is that of a real human form of a scourged, crucified man. It is not the product of an artist. The blood stains are composed of hemoglobin and also give a positive test for serum albumin. The image is an ongoing mystery and until further chemical studies are made, perhaps by this group of scientists, or perhaps by some scientists in the future, the problem remains unsolved.
Catania Conference Press Release re 1988 Carbon Dating
Press release, 27/05/2019
after the conference held in Catania on 23/05/2019 entitled
Dating of the Turin Shroud: everything must be redone
Statisticians, historians, physicists, mathematicians and Turin Shroud experts have stated today that we need to reevaluate the history of the Turin Shroud, and it all starts at the University of Catania.
The laboratories that dated the Shroud in 1988 with the radiocarbon dating method produced different results non-representative of the same phenomenon. Their paper was published in Nature on 16/02/1989.
The three laboratories did not mention in the Nature article the presence of conspicuous heterogeneous material, such as ancient cotton or blue and red threads. The existence of this material in the samples was learned via other sources.
The documentation released by the British Museum to independent researcher Tristan Casabianca in 2017 depicts a more complex picture than what was presented in the Nature article: for example, Arizona realized eight measurements and these raw measurements exhibit heterogeneities.
The procedures (chosen after more than ten years of negotiations between archaeologists, textile experts and the Holy See) were very far from perfect. Those are the introductory considerations pointed out by the statistician Prof. Benedetto Torrisi during the meeting held in Catania (Sicily).
The statistical analysis, performed by the research group coordinated by Prof. Torrisi, with Dr. Giuseppe Pernagallo, Prof. Emanuela Marinelli and Tristan Casabianca, was published in Archaeometry on 22 March 2019 (Radiocarbon dating of the Turin Shroud: New Evidence from Raw Data in Archaeometry (2019) ed Oxford University) confirms unequivocally the heterogeneity in the radiocarbon counts used for the dating, probably because of a contaminant not removed by the preliminary cleaning process, a relevant problem in the dating process of textiles, nowadays well established but not considered so relevant in 1988 as confirmed by Prof. Paolo Di Lazzaro, a physicist at ENEA of Frascati. Prof. Marinelli, laureate in Natural and Earth Sciences, says “the selected sample, chosen only from one point of the linen, very contaminated and mended, could not represent the entire cloth.” Torrisi and Pernagallo underline the strong heterogeneity between the three laboratories and inside the laboratories as alarms of non-representativeness, from a statistical point of view, of the textile samples.
Prof. Marco Riani, statistician of Parma University, says that “the statistical tests conducted in 2012 revealed that the dates provided by the three laboratories (Arizona, Oxford and Zurich) were with homogenous variability, but significantly different.”
The strongest evidence comes from the notorious Ward and Wilson test; this test and OxCal (a statistical software used by radiocarbon specialists), confirm the doubts on the official data combinability, strengthening this conclusion and providing further evidence of inhomogeneities for raw data and the individual estimates of the Arizona laboratory.
Casabianca affirms that “The new documentation released by the British Museum also provides insight into the elaboration and acceptation of 1989 article, including the internal (Anthos Bray) and external (Nature) peer review process. For the first time, we explain the Nature review process. The documentation supports the hypothesis of a reproducibility crisis – the difficulty to replicate many scientific studies – partly based on pressure to publish, confirmation bias and data dredging. This crisis might not only affect our current knowledge of the Turin Shroud but also future robust protocols”.
Casabianca strengthens the doubts about the correctness of the results and points out the fact that the reviews, dated and relative to the article of 1989, made by the referees of Nature, now part of this documentation, were too quick (about two months) to correctly evaluate the scientific value of that work.
The mathematician Prof. Bruno Barberis of Turin University affirmed that nowadays the process that caused the formation of the image remains unknown and further empirical and theoretical studies should be performed. Hence the Shroud image must be still considered unreproducible.
The participation from the audience was important. It was asked: the presence of such a great evidence of problems in the dating was already present in 1988, why did nobody individuate what was happening? Anyway, what could be a possible solution today? Barberis answered, “It seems impossible to reconstruct what happened in 1988, I’m not Sherlock Holmes, so it would be interesting to conduct an enquiry, but further research is needed, beyond the raw data obtained by Dr. Casabianca.”
Di Lazzaro says “It is surprising how the statistical expert of the British Museum who worked on the data did not note that in those data there was something wrong. But maybe there is a plausible explanation: in 1988 the accelerator mass spectrometry technique was new; it took the first steps. The people were still learning how to use it.” The alternative was to require another sample, confirming the failure of the technique, so they opted for the easiest alternative! We can just imagine what the consequences would have been in admitting that the technique was not adequate. But now it’s time to move on, and Prof. Di Lazzaro proposes a new possibility. Despite the C14 radiocarbon analysis today, after thirty years, it has evolved, to preserve the integrity of the linen, we could try an alternative route. From a chemical point of view the recent contaminant present in the cloth would be absent in the carbonized threads of the Chambéry fire in 1532, collected in 2002 from different points of the Shroud and preserved by the Turin Curia. That could be the starting point, fixing in mind that science is never definitive and never even aimed to provide the Truth with a capital T. Science can only provide approximations of truth, which we have shown today come closer and closer to the truth.
At this point, what emerges? The conclusions we reach, says Torrisi, are:
-
No doubts should remain: the radiocarbon dating of the Turin Shroud reported in Nature was not correct due to the strong data heterogeneity.
-
The sampling scheme does not offer the correct statistic representativeness of the linen. The heterogeneity among the measures provided by the laboratories depends on the area where the pieces of fabric have been cut.
-
The raw data confirm unequivocally the presence of heterogeneity of the results between the three laboratories.
-
Several statistical tests, parametric and non-parametric, show that the homogeneity problems of the data regard both raw and official data.
-
To increase our knowledge, new multidisciplinary studies should be proposed with the purpose of gathering more data to offer a complete vision of the physical, chemical and biological characteristics of the full Shroud, in order for researchers to work on reliable data.
-
A new dating is therefore necessary.

Chain of Custody: The Shroud of Turin and Its Early History
Daniel Clausen
The Shroud of Turin, an enigmatic and venerated relic in Christian history, has fascinated believers and skeptics alike. Known for its mysterious image of a crucified man believed by many to be Jesus Christ, the Shroud has been the subject of extensive research and is one of the most studied objects in the history of the world. The STURP Project, the only sanctioned study of the Shroud concluded, "We can conclude for now that the Shroud image is that of a real human form of a scourged, crucified man. It is not the product of an artist."
While it gained widespread public attention in the 14th century, numerous references and depictions suggest that it existed long before this period. Here, I will delve into the documented mentions and illustrations of the Shroud prior to its public reveal, tracing its journey through various historical contexts and geographies, clearly antedating the carbon-14 dating. Special thanks to Joe Marino, who collected many of these mentions in his list on Academia.edu, and also to Russ Breault, who also provides an excellent catalogue on Academia.edu, both of which have helped to compile this document.
1st Century - 3rd Century, The Earliest References
The earliest liturgical clue to the Shroud's ancient existence beyond the four gospels may well be The Hymn of the Pearl, also known as the Hymn of the Robe of Glory and can be found in the apocryphal book, The Acts of Thomas (216 AD). It is attributed to the poet Bardesane of Edessa, however its origin may be as early as 1st century:
I saw my image on my burial garment like in a mirror … (image on a linen shroud)
Myself facing outward … (dorsal image)
and myself facing inward … (frontal image)
As though divided, yet one likeness … (single cloth)
Two images, but one likeness of the King of Kings … (double image)
(Dreisbach, "Thomas and the Hymn of the Pearl," p.14)
The poem refers to the burial garment of Jesus, explicitly with his body and likeness. It should be noted that the photographic image that we know so well today would have been unable to be seen, and only the negative that is on the Shroud that provides only a “likeness” of his image.
Additionally, the Gospel of the Hebrews, a lost gospel from the first half of the second century, with some scholars even placing it in the first century, is quoted by Origen of Alexandria (184-253), and to the existence of the linen shroud at the time of its writing, saying: "When the Lord had given the linen cloth to the servant of the priest, he went and appeared to James." (Simon, "The Shroud and the Historical Jesus," p.4)
The Image of Edessa (33AD / 300s)
Many of the earliest potential references to the Shroud are associated with the Image of Edessa, also known as the Mandylion. The Mandylion was reputedly a miraculous image of Jesus' face imprinted on a cloth, which was kept in Edessa (modern-day Urfa, Turkey). This relic was venerated and played a significant role in the Christian East. According to some scholars, the Mandylion could have been part of the larger Shroud, folded in such a way that only the face was visible.
Historical accounts mention the arrival of the Mandylion in Edessa. Eusebius of Caesarea, a 4th-century church historian, recounted the story of King Abgar V of Edessa, who wrote to Jesus seeking a cure for his illness. According to the legend, Jesus responded with a letter and a cloth bearing his image, which miraculously healed the king. This cloth was then preserved in Edessa. The tenth-century Latin sermon "De Imagine Edessena" describes how the cloth was displayed and venerated in a golden chest during major Christian festivals.
The Doctrine of Addai (300s)
Another reference that may pertain to the Shroud is found in the "Doctrine of Addai," a Syriac document from the 4th century which regales the Edessa tradition. This text tells the story of Thaddeus of Edessa, one of the seventy disciples, who brought the sacred cloth bearing the image of Jesus to King Abgar. The description of this cloth closely aligns with the narrative of the Mandylion, suggesting that these early references might be interconnected accounts of the same relic.
The Acts of Thaddeus
The "Acts of Thaddeus," another early Christian text from the 6th century, recounts how Thaddeus (Addai) brought the holy image to Edessa. This text provides additional context to the narrative of the Doctrine of Addai, reinforcing the notion that a sacred cloth bearing the image of Christ was venerated in Edessa. This cloth, believed by some to be the Shroud, was considered a miraculous relic and an integral part of early Christian traditions in the region.
4th Century - Institutional Recognition
Pope Sylvester instituted by papal decree in 325 that the Church should celebrate the holy sacrifice of the Mass, representing the body and blood of Christ, on a linen cloth consecrated by the bishop, as if it were the clean Shroud of Christ. (Dreisbach, "Liturgical Clues to the Shroud's History")
This institution of covering the altar with linen representing the Shroud demonstrates knowledge of its existence and the shape and size of the cloth as a long rectangular linen. It explains a centuries-old tradition practiced in all denominations. Nothing could be more connected to the body and blood of Christ than the burial shroud that wrapped his crucified body represented by the linen covering the altar.
Bishop Theodore of Mopsuestia of Antioch (350-428), developed a Catechism with instructions before the celebration of the Mass: "When they bring up the oblation at the offertory, they place it on the altar for the completed representation of the passion so that we may think of Him on the altar as if He were placed in the sepulcher after having received the passion. This is why the deacons who spread the linens on the altar represent the figure on the linen cloths at the burial." (Dreisbach, "Liturgical Clues to the Shroud's History")
This adds another crucial element. Not only does the previous reference indicate the size and shape of the cloth but now Bishop Theodore establishes how the deacons who carry the cloth down the aisle represent the double image on the linen.
Evagrius Scholasticus (544)
Evagrius Scholasticus, a 6th-century Byzantine historian, provides another early reference to the Shroud. In his ecclesiastical history, he describes a miraculous image of Christ, known as the "acheiropoietos" (not made by human hands), which protected the city of Edessa from Persian invaders in 544 AD. While Evagrius does not explicitly mention the Shroud, his account of a protective image of Christ in Edessa aligns with the narrative surrounding the Mandylion and suggests the presence of a revered cloth image in the city during this period.
6th Century - Scriptural Evidence
A crucial reference appears in the translation of John 20:5-6 from the Mozarabic Rite of Holy Week: "Peter ran with John to the tomb and saw the recent imprints of the dead and risen man on the linens." (Dreisbach, "Liturgical Clues to the Shroud's History")
This is a critical reference as they re-translated scripture to reflect the image seen on the Shroud. It is not in the bible but goes back 1500 years. Why would they choose to translate the verse in this fashion unless it was based on knowledge of the Shroud's existence and what it contained? The previous references indicate an earlier origin, perhaps even 1st century and how the Shroud was integral to the symbolism of the Mass, the central sacrament of the Church.
Arculf in Jerusalem (670)
Another significant early reference comes from the Frankish bishop Arculf, who visited Jerusalem around 670 AD. His testimony, preserved by Adomnán of Iona in De Locis Sanctis, records that he personally saw and kissed a burial cloth of Christ approximately eight feet long, kept in the city under the custody of the Christians but contested by rival groups. Even the Caliph Muʿāwiya is said to have been involved in its adjudication, and the cloth was revered enough that miraculous properties were ascribed to it. This account is remarkable in that it provides an eyewitness report of the relic in Jerusalem within the 7th century—perfectly compatible with the Shroud of Turin if one considers the possibility that it was displayed folded, and that its faint image would not have been noticed at close range.
8th Century - The Iconoclastic Period
By the 8th century, icon images fell out of favor and were thought to be a form of idolatry. These "iconoclast" movements brought on widespread destruction of all sacred images starting in 726 until 787 and the Second Council of Nicea.
The Second Council of Nicea in 787 included the following statement as the basis to restore veneration of sacred images: "In the two years preceding the destruction of Jerusalem by Titus Vespasian, the faithful were warned by the Holy Ghost to leave Jerusalem and go to the kingdom of Agrippa, still allied to the Romans. Thus, going forth from the city, they took with them their most precious objects; this is how the images and other sacred objects were taken to Syria (Edessa) and were to be found there." (Ricci, The Holy Shroud, p. XXII)
The True-Likeness, first brought to Edessa by the Apostle Jude Thaddeus according to Orthodox tradition, was the principal argument to restore veneration of holy icons as a valid religious practice. A powerful advocate of icons was St. Theodore the Studite who referenced the Shroud as a full body image in which the Christ was wrapped and laid down in the sepulcher. (Marinelli and Fasol, Light from the Sepulcher, p. 9)
Regarding why Jude brought the sacred cloth to King Abgar, Theodore said it was: "To clearly grant us His divine features, our Savior who had been covered with it, imprinted the form of His own face and portraying it touching the cloth with His own skin." (Marinelli and Fasol, Light from the Sepulcher, p. 9)
Pope Stephen III gave his full support to restoring images to the revered place they once held with the following statement: "Christ spread out his entire body on a linen cloth that was white as snow. On this cloth, marvelous as it is to see…. the glorious image of the Lord's face, and the length of his entire and most noble body, has been divinely transferred." (Trenn, "The Shroud of Turin: A Parable for Modern Times," p. 5)
The logical inference of these statements is that if Jesus preserved an image of himself on his linen shroud, it was done to offer his likeness as a means of facilitating worship and therefore fully justifies the use of icon images for the same purpose.
The Journey to Constantinople
In the 11th century, significant changes occurred due to political and religious upheavals. The Shroud is believed to have been moved from Edessa to Constantinople, the capital of the Byzantine Empire. Historical records from this period indicate that numerous relics, including the Shroud, were transferred to Constantinople to protect them from invasions and desecration.
One such record, the "Narratio de Imagine Edessena," an anonymous Latin text, notes that the Shroud was kept in Constantinople in a golden case and was shown only to the Emperor, highlighting its significance and the care taken to preserve it. Additionally, the Tarragona Manuscript, dated between 1075 and 1099, confirms the Shroud's survival through the Byzantine iconoclasm and its esteemed status in the imperial relic collection.
10th Century - The Transfer to Constantinople
By 944, Edessa had fallen to Islam and the emperor was concerned over the safety of the most holy relic of Christendom. After trading 200 prisoners of war and bags of silver, the sacred cloth was retrieved from Edessa without bloodshed and brought to Constantinople. Gregory the Archdeacon of the Hagia Sophia delivered a sermon in the palace on August 16, 944. During the ceremony, the cloth was laid out on the emperor's throne and crowned with the emperor's crown. Standing next to the linen Gregory points out the following features:
"The splendor has been impressed uniquely by the drops of agony sweat sprinkled from the face…These are truly the beauties that produced the coloring of Christ's imprint, which has been embellished further by the drops of blood sprinkled from his own side… blood and water there, sweat and image here." (Guscin, "Sermon of Gregory Referendarius," p. 12)
A clear reference to the side wound is proof it was more than a face image. He describes "blood and water" yet on the Shroud we know the side wound shows the separation of blood and serum which appears clear like water and indicates a wound that occurred after death when the blood is no longer circulating. The mention of "sweat" as a cause of the image indicates an absence of paint, just as we see on the Shroud.
11th Century - Full Body Descriptions
A Latin version of the first century Abgar legend shows the following response from Jesus to King Abgar's request for him to come to Edessa to heal the king. Once again, we see a clear reference to the cloth brought to Abgar as a full body image of Jesus, not just his face: "But if you wish to see my face in the flesh, behold I send to you a linen, on which you will discover not only the features of my face, but a divinely copied configuration of my entire body." (Drews, In Search of the Shroud of Turin, p. 46)
The Hungarian Pray Manuscript
A critical piece of evidence supporting the Shroud's existence before the 14th century is the Hungarian Pray Manuscript, created between 1192 and 1195. This manuscript, named after its discoverer György Pray, contains illustrations that remarkably resemble the Shroud of Turin. Among these is the depiction of Jesus with crossed arms over his pelvic area, and thumbs tucked under the hand, details unique to the Shroud. The manuscript also shows what appear to be L-shaped
burn marks, identical to those on the Shroud. These similarities strongly suggest that the Shroud was
known and perhaps even seen by the manuscript's illustrator.
There are 12 specific attributes of the Shroud that are documented in the codex found in the Hungarian Pray Manuscript dated to 1192. The artist who crafted the image was an eyewitness to the Shroud kept in Constantinople sometime between 1160 and 1170 when King Bela III of Hungary served in the court of the emperor. Captured in this document is the exact same size and dimension of the Shroud (a long narrow rectangular cloth enveloping the body lengthwise), the unique herringbone pattern weave, and an "L" shaped pattern of burn holes unique to the Shroud of Turin.
The Menaion
Further supporting the Shroud's existence in the Byzantine period are liturgical references. The "Menaion," a liturgical book of the Eastern Orthodox Church, includes hymns and prayers that reference the burial cloth of Christ. These texts, dating back to the 12th century, describe the cloth in terms consistent with the Shroud, indicating that it was an object of veneration and incorporated into the religious practices of the time.
12th Century - Contemporary Accounts
From Ordericus Vitalis who wrote Ecclesiastical History circa 1141: "A precious linen, on which he had wiped off the sweat from his face, and on which an image of this same Savior shines forth, miraculously painted (imprinted): this image shows to whoever looks upon it the appearance and size of the Lord's body." (Drews, In Search of the Shroud of Turin, p. 47)
The Relics of Constantinople
In the 12th century, the Shroud's presence in Constantinople is further corroborated by various inventories and descriptions of relics. William of Tyre, a medieval historian, documented that during King Amaury I of Jerusalem's visit in 1171, Emperor Manuel I Comnenus displayed numerous relics of the Passion, including the Shroud (referred to as the "sindon"). This entry reinforces the notion that the Shroud was part of the imperial relic collection and venerated as a significant artifact of Jesus' Passion.
The Fourth Crusade and the Sack of Constantinople
The Fourth Crusade's sack of Constantinople in 1204 marked a pivotal moment in the history of the Shroud. The city was ransacked by Crusaders, and many relics were looted and transported to Western Europe. Robert de Clari, a French knight who participated in the Fourth Crusade, wrote in his chronicle that he saw the Shroud of Christ in the Church of St. Mary of Blachernae in Constantinople: "But among the rest [of the churches in Constantinople], there was also another which was called Saint Mary of Blachernae, within which was the shroud wherein Our Lord was wrapped. And on every Friday that shroud did raise itself upright, so that the form of Our Lord could clearly be seen. And none knows - neither Greek nor Frank (French) - what became of that shroud when the city was taken." (Wilson, The Shroud: The 2000-Year-Old Mystery Solved, p. 108)
After the city was sacked and pillaged, Theodore Angelus of Constantinople, brother of the emperor, crafted a letter of protest in 1205 to Pope Innocent III that read: "In April last year, a crusading army, having falsely set out to liberate the Holy Land, instead laid waste the City of Constantine. During the sack, troops of Venice and France looted even the Holy Sanctuaries. The Venetians partitioned the treasures of gold, silver, and ivory, while the French did the same with the relics of the saints and... Most sacred of all, the linen in which our Lord Jesus Christ was wrapped after his death and before the resurrection. We know that the sacred objects are preserved by their predators, in Venice, in France, and other places, the sacred linen in Athens." (Wilson, The Shroud: The 2000-Year-Old Mystery Solved, p. 214)
13th Century - Additional References
From Gervase of Tilbury circa 1213: "The story is passed down from Archives of Ancient Authority that the Lord prostrated himself with his entire body, on the whitest linen, and so by divine power there was impressed on the linen a most beautiful imprint of not only the face, but the entire body of the Lord." (Drews, In Search of the Shroud of Turin, p. 48)
It is important to note how Gervase makes it clear the linen cloth has a long history pre-dating 1213 when he made this statement.
Throughout the 13th century, references to a burial shroud of Christ appear in various texts and inventories across Europe. These references, while not always directly naming the Shroud of Turin, describe a cloth bearing the image of Christ, suggesting that the relic was known and venerated in different locations.
For instance, a 1205 letter from Theodore Angelos, the ruler of Epirus, to Pope Innocent III mentions the sacred burial cloth of Christ. This letter indicates that the relic was highly valued and sought after by Christian leaders during this period.
The Knights Templar and the Shroud
The Shroud's disappearance following the sack of Constantinople in 1204 and its reappearance in the 14th century is a period shrouded in mystery. Researcher Barbara Frale has found evidence in the trial records of the Knights Templar that suggests the Shroud was in the possession of the order before it was suppressed. According to these records, the Shroud had disappeared during the sack of Constantinople and did not surface again until 1353, when it was displayed in a church at Lirey in France by the nephew of Geoffroi de Charney, The Templar Preceptor of France.
Arnaut Sabbatier's Testimony
An intriguing account supporting the Templar possession of the Shroud comes from Arnaut Sabbatier, a young Frenchman who entered the order in 1287. He testified that as part of his initiation, he was taken to a secret place accessible only to the brothers of the Temple. There, he was shown a long linen cloth on which was impressed the figure of a man and instructed to venerate the image by kissing its feet three times. This testimony provides a compelling link between the Templars and the Shroud, suggesting that they may have safeguarded it during the period it was thought to be lost.
The Shroud of Turin Research Project (STURP) and Carbon-14 Dating
In 1988, the Shroud of Turin was subjected to carbon-14 dating by three independent laboratories, coordinated by the Shroud of Turin Research Project (STURP). The results indicated that the linen cloth dated to between 1260 and 1390 AD, suggesting it was a medieval creation rather than a relic from the time of Christ. However, many researchers and scholars have questioned these results, citing potential contamination, repair patches, fire, and the presence of a bioplastic coating on the linen as factors that could have skewed the dating process.
In 2013, Dr. Giulio Fanti conducted infrared dating on threads from the Shroud of Turin, concluding that the fibers dated between 300 BC and 400 AD, potentially placing the Shroud within the timeframe of Jesus' life. More recently, in 2022, Italian scientist Liberato De Caro used a Wide-Angle X-ray Scattering (WAXS) method to date the Shroud. This technique examined the natural aging of cellulose fibers and suggested that the Shroud is around 2,000 years old, aligning with the period of Christ's death and resurrection.
The fact that one sample was cut from the most held and handled part of the cloth documented to have been held up manually for exhibition by church officials over 275 times from 1418 to 1694 is clear they chose the worst possible sample location to determine the cloth's age.
Despite the carbon-14 dating results, the historical references and depictions of the Shroud prior to the 14th century provide compelling evidence for its existence and veneration well before the medieval period. The early references to the Image of Edessa, the accounts of Evagrius Scholasticus, and the illustrations in the Hungarian Pray Manuscript all contribute to a rich historical narrative that supports the Shroud's antiquity. Additionally, new dating techniques such as the infrared test and the WAXS x-ray test have firmly placed the dating of the Shroud in the first century, in a repeatable, testable way.

-
2022 (De Caro, WAXS): Dates it to ~2,000 years old.
-
Combined with history, scientific challenges to C-14 suggest the Shroud's origin plausibly lies in the 1st century.
Conclusion
The Shroud of Turin's history prior to its 14th-century public reveal is supported by a variety of references and depictions from different periods and regions. While the 1988 carbon-14 dating results have sparked controversy and debate, they represent only a single line of inquiry. Against this, we find a web of historical and literary traces stretching deep into Christian antiquity—the Gospel accounts of the burial cloths, possible allusions in apocryphal works such as the Hymn of the Pearl, early references to acheiropoieta (images “not made by hands”), and subsequent Byzantine traditions surrounding a mysterious burial shroud. Taken individually, each of these witnesses might be explained away as referring to other cloths, traditions, or pious inventions. But taken together, they form a cumulative
case that is difficult to dismiss. Even if all of these references do not point with certainty to the Shroud of Turin, it is improbable that none of them preserve a memory of the same relic. Thus, the balance of evidence suggests a pre-medieval existence for the Shroud, standing as a historical counterweight to the contested C-14 test and reinforcing its claim to be not merely an artifact of medieval piety, but a relic with roots in the earliest centuries of Christianity.
