Like a tennis ball, the hypotheses are whacked back and forth. One scientist proposes a new idea of how the mysterious Shroud could have been produced only to have another researcher argue that it was impossible.
In the Shroud was subjected to carbon dating technology which dated it to the 13th century. Predictably, the result has been criticised for a range of reasons. The most recent critique argues that the samples used for the test were taken from an edge of the Shroud that was not simply patched in the middle ages, but patched with a difficult-to-detect interweaving.
The Carbon tests it is argued were therefore compromised. A different sort of dating test was conducted by Giulio Fanti of Padua University in This technology uses infra-red light and spectroscopy to measure the radiation intensity through wavelengths, and from these measurements a date can be calculated.
However, a good detective does not rely on one piece of evidence.

Instead he gathers and weighs all the facts. Here are the pieces of evidence which I find compelling.
It is not a stain, nor is it painted on the Shroud. It is not burned on in a conventional heat application method. Instead it is seared on to the cloth with a technology that has yet to be explained. The image of the man on the Shroud can be read by 3D imaging technology.
Paintings fail this test.
Pollen from the Shroud is not only from the Jerusalem area, but from Turkey and the other places the Shroud is supposed to have resided. Dust from the area of the image by the knees and feet is from the area around Jerusalem. The Shroud details are perfectly consistent with first-century Jewish burial customs. There are even microscopic traces of the flowers that would have been used in the burial-flowers that grew locally and were known to be used for burial.

In addition, traces of the spices used for Jewish burial have been discovered. The bloodstains on the Shroud are real human blood, not paint. The samples were then taken to the adjacent Sala Capitolare where they were wrapped in aluminium foil and subsequently sealed inside numbered stainless-steel containers by the Archbishop of Turin and Dr Tite.
Samples weighing 50 mg from two of the three controls were similarly packaged. The three containers containing the shroud to be referred to as sample 1 and two control samples samples 2 and 3 were then handed to representatives of each of the three laboratories together with a sample of the third control sample 4which was in the form of threads.

All these operations, except for the wrapping of the samples in foil and their placing in containers, were fully documented by video film and photography. The laboratories were not told which container held the shroud sample. Because the distinctive three-to-one herringbone twill weave of the shroud could not be matched in the controls, however, it was possible for a laboratory to identify the shroud sample. If the samples had been unravelled or shredded rather than being given to the laboratories as whole pieces of cloth, then it would have been much more difficult, but not impossible, to distinguish the shroud sample from the controls.
With unravelled or shredded samples, pretreatment cleaning would have been more difficult and wasteful. Because the shroud had been exposed to a wide range of potential sources of contamination and because of the uniqueness of the samples available, it was decided to abandon blind-test procedures in the interests of effective sample pretreatment.
But the three laboratories undertook not to compare results until after they had been transmitted to the British Museum. Also, at two laboratories Oxford and Zurichafter combustion to gas, the samples were recoded so that the staff making the measurements did not know the identity of the samples.
Controls The three control samples, the approximate ages of which were made known to the laboratories, are listed below. Two were in the form of whole pieces of cloth samples 2 and 3 and one was in the form of threads sample 4. Plumley for the Egypt Exploration Society in On the basis of the Islamic embroidered pattern and Christian ink inscription, this linen could be dated to the eleventh to twelfth centuries AD.
This corresponds to a calendar age, rounded to the nearest 5 years, of cal BC - AD 75 cal at the 68 per cent confidence level 5 where cal denotes calibrated radiocarbon dates. Measurement procedures Because it was not known to what degree dirt, smoke or other contaminants might affect the linen samples, all three laboratories subdivided the samples, and subjected the pieces to several different mechanical and chemical cleaning procedures.
All laboratories examined the textile samples microscopically to identify and remove any foreign material. Zurich precleaned the sample in an ultrasonic bath. After these initial cleaning procedures, each laboratory split the samples for further treatment. The Arizona group split each sample into four subsamples. One pair of subsamples from each textile was treated with dilute HCL, dilute NaOH and again in acid, with rinsing in between method a. The second pair of subsamples was treated with a commercial detergent 1.
The Oxford group divided the precleaned sample into three.Science Proves Shroud Of Turin Is Authentic
Two of the three samples were then bleached in NaOCL 2. The Zurich group first split each ultrasonically cleaned sample in half, with the treatment of the second set of samples being deferred until the radiocarbon measurements on the first set had been completed.
The first set of samples was further subdivided into three portions. One-third received no further treatment, one-third was submitted to a weak treatment with 0. After the first set of measurements revealed no evidence of contamination, the second set was split into two portions, to which the weak and strong chemical treatments were applied.
