The Shroud of Turin and the Bas-Relief Hypothesis

A Multi-Disciplinary Response to Cicero Moraes

It’s not every day that an ancient piece of cloth inspires passionate debate across scientific, historical, and theological domains. The Shroud of Turin—believed by many to be the burial cloth of Jesus of Nazareth—remains one such artifact. Recently, 3D forensic modeler Cicero Moraes offered a theory suggesting that the Shroud’s image could have been formed by a bas-relief or similar artistic method. His approach, while visually creative and technically polished, falls short under close multidisciplinary scrutiny. This post offers a distinct response to Moraes’s claims, building on scientific, historical, and theological insights not commonly explored in rebuttals.

This blog is best read in tandem with my full-length research paper, Sacred Threads: The Shroud of Turin in Scriptural and Jewish Context, which explores the Shroud’s alignment with first-century Jewish burial customs, historical testimony, and theological implications.

What Moraes Proposes

Moraes, known for facial reconstructions using forensic 3D modeling, applies his expertise to suggest that the Shroud image could have been produced via a bas-relief or similar physical object pressed into contact with cloth. He argues that variations in image intensity correspond with relief depth, implying an artistically engineered result. Even if a digitally draped image resembles the Shroud visually, it does not replicate the chemical, microscopic, or physical properties confirmed by direct testing.

While Moraes claims his method accounts for the image’s anatomical realism and general proportions, this theory commits a fundamental flaw: it presumes that physical contact explains the Shroud’s image without adequately accounting for multiple properties of the image that physical contact alone cannot replicate.


1. Spatial Encoding: A Property No Artist Could Have Predicted

Perhaps the most baffling feature of the Shroud image is its three-dimensional spatial encoding. The image intensity correlates directly with cloth-body distance—not pressure, not ink density, not pigment layering. This was first revealed through analysis with the VP-8 Image Analyzer in 1976. Unlike typical photographs or paintings, which distort when subjected to 3D mapping, the Shroud’s image produced a coherent 3D relief.

No other known ancient image demonstrates this property. Not the Mona Lisa. Not the Fayum portraits. And certainly not any medieval bas-relief artifact. If this were an artist’s invention, it would be a feat of engineering far ahead of its time—yet without precedent or replication.¹


2. Top-Down Image Formation: Superficial Yet Precise

Under microscopic analysis, the image resides only on the outermost 1–2 microns of the linen fibrils—less than the thickness of a red blood cell (about 200 nanometers deep). There is no evidence of capillary action or ink penetration. In fact, the image does not fluoresce under ultraviolet light, unlike known burns or scorches.²

Even more remarkable, the image was not formed by any pigments, paints, dyes, or binders. STURP (the Shroud of Turin Research Project) confirmed this through X-ray fluorescence, infrared spectroscopy, and microchemical testing.³ A contact image like Moraes’s model would almost certainly leave behind more than just surface discoloration—it would involve deformation, capillary wicking, and distortion.

None of that is present.


3. The Draping Problem: Undistorted Yet Impossible

One of the most overlooked difficulties for contact theories like Moraes’s is the issue of cloth draping. When a fabric is laid over a three-dimensional form—like a human face or torso—it conforms to topography, creating distortion. Yet the Shroud image is not distorted. Dr. John Jackson’s cloth-draping experiments, conducted using life-sized manikins and laser-mapped topography, revealed that a contact model would produce severe horizontal distortions, especially around the cheeks, sides of the face, and body flanks.⁴

Moraes’s model does not address this. He simply assumes contact transfer without distortion, despite this being a physical impossibility.


4. The Blood Is Not the Image

In Moraes’s renderings, it appears that the image and bloodstains emerge as part of the same modeling exercise. This assumption ignores a fundamental detail: the blood is not part of the image. The bloodstains on the Shroud are anatomically accurate, distinguishable under spectroscopy, and precede the image.⁵

Furthermore, the blood itself is consistent with human, complete with bile pigments and serum separation.⁶ High-resolution UV fluorescence photography revealed serum halos consistent with postmortem clotting—a phenomenon an artist in the 13th century could not have anticipated, let alone replicated.


5. Medical Forensics: The Signature of Death

The man of the Shroud shows evidence of rigor mortis, postmortem blood flow, and anatomical consistency with Roman crucifixion practices—such as injuries to the wrist (not palms), scourge marks consistent with a Roman flagrum, and separated shoulder joints. These forensic details were confirmed by multiple pathologists, including Pierre Barbet and Dr. Robert Bucklin.⁷

A static bas-relief would be hard-pressed to incorporate such dynamic physiological details—especially those visible only to modern forensic science.


6. Historical Inconsistency: The “Mask of Agamemnon” Error

Moraes likens the Shroud to the Mask of Agamemnon, discovered in Mycenae. But this analogy is flawed. The mask is a hammered gold funerary covering—not a contact image, not a cloth-based medium, and not comparable in its material or formation process. It is akin to comparing a fingerprint to a coin impression: both have contours, but their origins and features are categorically different.

Additionally, no artistic tradition—Byzantine, Romanesque, Gothic, or otherwise—shows any precedent for the unique properties of the Shroud. There is no evolutionary trail, no lesser prototypes, and no workshop records for such a technique.


7. Dating and the WAXS Revolution

Moraes leans on the 1988 radiocarbon dating that placed the Shroud in the medieval period. However, subsequent textile studies (including those using Wide-Angle X-ray Scattering, or WAXS) have called this conclusion into serious question. Dr. Tristan Casabianca and others have published peer-reviewed analyses showing that the original 1988 samples were likely taken from a repaired section of the cloth.⁸

Dr. Liberato De Caro’s 2022 WAXS study dated Shroud fibers to the 1st century with 95% confidence.⁹ These results are not alone. FTIR and Raman spectroscopy studies also indicate ancient linen aging consistent with a 1st-century origin.


8. Image Replication Experiments: Every Attempt Falls Short

Countless scientists and artists have attempted to replicate the Shroud using radiation, heat, pigments, or chemical reactions. None have succeeded in reproducing all the known properties:

  • Superficiality to the top 1–2 microns
  • No fluorescence
  • No pigment or binder
  • Correct 3D spatial encoding
  • Anatomical realism
  • No distortion from draping
  • Bloodstains that predate the image

For instance, Giulio Fanti’s corona discharge models produced partial similarities, but failed to account for the blood-image separation and lacked consistency in fibril coloration. Luigi Garlaschelli’s painting attempts were visible under microscopy as having pigment residue, and failed UV tests.¹⁰

In science, replication is key. The Shroud remains an unreplicated artifact.


9. Philosophical Honesty: When the Evidence Pushes Back

Moraes is undoubtedly skilled in digital modeling. But science demands more than plausible rendering—it demands explanatory power.

When an artifact defies replication, resists simplistic categorization, and produces multiple layers of interdisciplinary anomaly, the burden is not on defenders of authenticity to explain everything with finality. Rather, the burden shifts to the skeptic to produce a model that explains all the data better. Moraes’s model does not come close.

One may rightly remain agnostic about the Shroud’s full origin. But if one is to speak honestly, scientifically, and historically, then Moraes’s bas-relief theory fails the test of coherence, completeness, and explanatory rigor.

As John 1:14 says, “The Word became flesh and dwelt among us.” If the Shroud is what it appears to be, then it is not only an object of curiosity—but a signpost pointing toward that Incarnation.


Conclusion

Moraes’s paper may impress with its digital artistry, but it fails to grapple with the depth of the data.

This is simply an already disproven hypothesis dressed in new digital clothing. It recycles contact-based theories that have long been shown inadequate—and gives them a fresh look without fresh substance. The headlines may be new, but the assumptions are not. And unfortunately, this is where the media leads, not where the science does.

Decades of research—especially from the STURP team—have already demonstrated that the image on the Shroud is not the result of painting, burning, scorching, or any known artistic method. As STURP concluded in 1981:

“The image is not the result of any known mechanism—be it rubbing, painting, scorching, or vapor contact.”
—STURP Final Report

A valid theory of the Shroud must explain not just what we see,
but how we see it—and how it got there.

The Shroud is not just mysterious. It’s measurable. And the more we measure,
the more it pushes back against every naturalistic explanation.

      Dear Mr. Moraes,

      Thank you again for your thoughtful reply and for sharing your publication. I did in fact read your article prior to writing my blog, and I found it both visually compelling and intellectually engaging. Your modeling skills are truly exceptional, and I deeply respect the creative and technical precision of your work.

      That said, I wrote my post precisely because your approach sparked important questions that I believe deserve further exploration—especially in light of the data from the STURP investigation and subsequent forensic studies. If you’re open to it, I’d love to continue this exchange with a few specific points that I hope you might consider engaging with:

      STURP’s Conclusion Against Artistic Methods
      As you know, the 1978 Shroud of Turin Research Project concluded that “the image is not the result of any known artistic technique.” They found no evidence of pigments, binders, or dyes. The image itself is superficial—only penetrating the top 1–2 microns of the outer fibrils—and exhibits no directional strokes or mechanical deformation. Given these findings, I wonder how your modeling hypothesis might engage with STURP’s conclusion that the image is not a product of artistic application or transfer.
      Blood First, Image Second
      Chemical analysis by Heller and Adler confirmed that the bloodstains on the Shroud are real human blood and contain high levels of bilirubin, consistent with severe trauma. More significantly, there is no image underneath the blood—indicating that the blood transferred first, and the image formed afterward. I would be interested to know how your model accounts for this important forensic sequence.
      Distinction from the Bas-Relief Hypothesis
      While your method is clearly digital and rooted in modern 3D facial reconstruction, some readers have likened it to a variation of the bas-relief hypothesis. That approach has already faced strong critique due to its inability to replicate the Shroud’s consistent image depth, negative properties, and undistorted proportions. Could you help clarify how your method differs from bas-relief models, and whether it avoids those known limitations?
      Burst of Energy Hypothesis (Di Lazzaro et al.)
      Research by Dr. Paolo Di Lazzaro and the ENEA team has shown that brief, high-intensity bursts of UV laser light can produce superficial image discoloration on linen fibers that closely resemble those on the Shroud. While no natural process is currently known to generate that kind of energy, the experiments at least demonstrate a mechanism that can replicate the physical properties of the image without contact or pigment.
      I wonder—do you see any way your modeling work could be adapted to explore or align with this kind of energy-based hypothesis? Could your forensic reconstructions be paired with scenarios that support sudden photonic or radiant image formation? I ask not in opposition to your work, but out of genuine curiosity and a desire to explore areas of convergence rather than divergence.

      Again, I ask these questions with sincere respect. Your work is clearly the product of great expertise, and I’d be honored to continue this dialogue in a spirit of collegial inquiry. Thank you again for your gracious tone and your willingness to engage.
