Abstract: The Shroud of Turin is an important archaeological textile showing the front and back images of a man with blood marks consistent with scourging and crucifixion. The cloth has been proposed to represent either the burial linen of the historical Jesus of Nazareth or the product of a medieval artist. Almost forty-five years ago, it was reported that enzymatic digestion of blood from fibers taken within a Shroud image area revealed no image-type coloration underneath. Such findings led to the suggestion that blood was transferred to the cloth first, protecting such areas from subsequent image formation. Although often evoked as a form of scientific proof for the Shroud’s authenticity, there has been no further experimentation to explore this interesting concept. Given the peculiar feature of colored fibers existing adjacent to non-colored fibers within image areas of the Shroud, the issue has been raised that prior digestion studies may have been confounded by neighboring uncolored fibers underneath the blood. Additionally, it has been proposed that blood may have a “bleaching effect” on fabric, which could revert colored fibers in a scenario where the blood was added secondarily to a created image. The ordered relationship between blood and image is particularly intriguing given that recent findings using nanosecond pulses of ultraviolet energy to create superficial and Shroud-like coloration on linen were shown to vaporize bloodstains. In the current report, studies were performed to investigate factors that might potentially relate to the sequential order of blood and image addition to the Shroud of Turin. These studies show that addition of blood to acid-treated linen nullifies subsequent coloration, providing an example of no image underneath bloodstains with these conditions. The “bleaching effect” of blood was evaluated and shown to be restricted to only one out of three coloration systems that were examined, leading to the general conclusion that blood added after coloration is unable to reverse it. Finally, these studies document that linen underneath blood (or serum) was affected by energy transfer from radiation, even under conditions corresponding to latent coloration.
