Arizona, Oxford, and Zurich received divisions of one edge strip, not samples from three locations. Threads attributed to the radiocarbon region carried cotton, a dyed plant-gum coating, and chemical differences that led to a repair conclusion. Statistical analyses found heterogeneity and allocation-dependent position trends, while the raw measurements released after a legal request failed homogeneity.

The result therefore does not establish the age of the whole Shroud. The 2026 paper found no repair in two retained Arizona fragments under its methods, but added no new date, no new location, and no physical main-body comparison. See 1988 Carbon Dating and The 2026 Arizona Paper.

STURP tested the image with chemistry, microscopy, photography, infrared, ultraviolet, and X-ray methods. The team found no image pigment, no dye, no paint layer, no brush direction, and no material build-up.

The blood areas tested as real blood, not red paint. The image is a surface change in linen fibers. See STURP 1978 and Image.

Leonardo da Vinci was born in 1452. The Shroud had been publicly displayed at Lirey about a century earlier, and the de Charny family transferred it to the House of Savoy in 1453. The Pray Codex preserves its distinctive body-and-cloth cluster around AD 1192–1195. Leonardo cannot have made an artifact already known before he was born.

The proposed technique also fails materially. No camera coating, silver compound, projection chemistry, or painted negative forms the body image. A famous inventor and a clever photographic story cannot overcome chronology or replace the absent image-forming substance.

The secure Western custody begins at Lirey, but the earlier record is not blank. The Edessa image reached Constantinople in AD 944; a sermon connected it with Christ's side blood; the Pray Codex preserves a Shroud-like burial scene by AD 1195; and Robert de Clari described a body-bearing burial shroud before the sack of 1204. The post-sack ownership gap remains, while Templar custody is only a proposed bridge. See History Before 1356.

Modern reproductions copy the look from a distance, but fail the technical properties together. A painting can reverse tones. A rubbing can make a faint body. Heat or ultraviolet energy can yellow a surface. None combines negative-like behavior, useful spatial information, microscopic surface color, no image medium, real blood laid down first, and the complete wound record on one linen.

“Looks similar” is therefore not the standard. A successful reproduction must explain the material object and its sequence, not merely produce a photograph that reminds the viewer of it. Image Formation tests the proposed routes feature by feature.

A 2025 digital study draped virtual cloth over a full three-dimensional body and a shallow relief. The relief produced a less laterally distorted projection, so the author proposed that a relief could explain the Shroud's body proportions.

The simulation addresses outline geometry only. It did not form an image on linen, reproduce fibril-level surface color, create the measured intensity relationship, or place genuine crucifixion blood before the body image. A sculpted relief would still require pigment, powder, liquid, or heat to mark the cloth, and each route leaves physical effects absent from the Shroud.

The study is a useful geometry exercise, not a reproduction or a forgery mechanism. It cannot transform a digital resemblance into evidence that a medieval relief made the cloth.

No. The d'Arcis memorandum records a bishop's accusation during a dispute over display and jurisdiction; it does not preserve an artist's name, a verifiable confession, a method, or the object allegedly used. Its painted-forgery description conflicts with the cloth's measured lack of an image-forming paint layer, dye, or brushwork. The papal response regulated continued display rather than declaring or destroying a proven fake.

No image-forming paint was established. McCrone interpreted red particles on adhesive tapes as artist's pigment. The broader chemical, spectral, X-ray, infrared, ultraviolet, photographic, and microscopic record found that those particles did not map or supply the body image. The wound areas contain blood material, while the body image is altered linen without a sufficient pigment, binder, brush direction, or applied coating.

No. The modern reconstruction used a body form, pigment, acid aging, heat, and separately added blood-like marks to imitate the Shroud's appearance. It did not reproduce the microscopic surface coloration, lack of image medium, useful body-distance information, or undisturbed real blood beneath the later image. Copying selected visual traits by disclosed modern steps does not reproduce the Shroud's physical process.

It means the Shroud cannot be dismissed by a slogan, a digital outline, or one unrepresentative sample. When each claim is checked against the whole object, its explanatory gaps remain while independent evidence continues to converge. The cloth remains a physical record of Jesus' Passion and burial, consistent with the linens left when He rose, and confirms that the Gospel accounts describe real history.
