Scientists Suggest Turin Shroud Authentic

A team of researchers from the National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA), Italy, has found that the Shroud of Turin is not a fake and the body image was formed by a sort of electromagnetic source of energy.

Italian researchers in the report, published by the ENEA Research Centre of Frascati, describe their findings obtained during five years of experiments and deny the hypothesis that the Shroud of Turin is a medieval forgery.

The researchers, including Paolo Di Lazzaro, Daniele Murra, Enrico Nichelatti, Antonino Santoni and Giuseppe Baldacchini, successfully achieved a superficial coloration similar to that of the body image embedded onto the Shroud of Turin by excimer laser irradiation (spectrum of the emitted light in the ultraviolet and vacuum ultraviolet) of raw linen fabrics.

They obtained at least one fiber colored across the sub-micrometer depth, comparable with thinnest coloration depth observed in the Turin Shroud fibers. However, they found that the total radiation power, required to color a linen surface corresponding to a human body, makes impossible the reproduction of the Turin Shroud image by using a single laser.

The researchers also produced latent coloration that appears after artificial or natural aging of linen following laser irradiations that at first did not generate any visible effect, and identified distinct physical and photochemical processes, which have played a role in the generation of the body image on the Turin Shroud.

“Our research proves that it is very difficult (almost impossible) replicating today all the main physical and chemical characteristics of the body image embedded into the Shroud of Turin,” says Dr. Paolo Di Lazzaro, lead author on the report and senior researcher at the ENEA Research Centre of Frascati, in his interview with

“As a consequence, it appears unlikely a forger may have done this image with technologies available in the middle Age or earlier. The probability the Shroud is a fake is really very very low. On the other hand, our results, taken alone, cannot prove the Shroud is the burial cloth of Jesus Christ. One should add our results to all the other historical, medical, palinilogical, textile evidences accumulated in the last 35 years.”

“It is possible that the body image was formed by a sort of electromagnetic source of energy. Our experiments show that many (not all) the peculiar properties of the body image of the Shroud are produced by a burst of photons in a very narrow range of parameters (pulse duration, intensity, number of shots). In particular, vacuum ultraviolet photons account for the very thin coloration depth, the hue of color and the presence of image in linen parts not in contact with the body. Obviously, it does not mean the image was produced by a laser. Rather, the laser is a powerful tool to test and obtain the light parameters suitable for a shroud-like coloration.”

Answering to the question on when and how the image on the Shroud of Turin was made, Dr. Di Lazzaro comments: “Our research does not address the problem of when, it gives some hints on how. In fact, in our opinion, the most important question is not when the Shroud was made. Independent of its age, middle age or first century, the most important question, the “question of questions” is how it is possible to do an image like the Shroud body image.”

“For sure, none of the hundreds attempts to obtain a shroud-like image by using chemical contact techniques – i.e. adding chemical substances like colors, powders, etc. – has achieved good results. Usually, the chemical approach gives similar macroscopic results, but it fails when analyzing the coloration with a microscope. At the microscopic level, the contact chemical approach does not give Shroud-like results. On the contrary, attempts using various radiations (vacuum ultraviolet photons, electrons from a corona discharge) give a coloration that looks shroud-like even at the microscopic level,” concludes Dr. Di Lazzaro.
