The Shroud is true, here is the evidence ...

1) The body image of the Shroud is a false negative: technology discovered and used in photography only in 1850.
2) The nails are fixed in the wrists of the man of the Shroud: but in all the ancient representations of the crucifixion the nails are planted in the hands, even if in this way the body could not remain hung on the cross. The hypothetical medieval counterfeiter could not have known or in any case would have had no reason to contradict the representations of tradition, thus risking giving rise to suspicions.
3) The image of the left leg is shorter than the right: a consequence of the nailing method of the feet and the sudden cadaveric rigidity, two aspects unknown in the Middle Ages, having been discovered only in recent times.
4) On the right side of the ribcage there is a large stain of blood and serum: no hypothetical medieval counterfeiter could have known that this is a consequence of the instantaneous death by breaking the wall of the heart, a recent discovery of medicine.
5) The bloodstains are clear and under them there is no body image: these characteristics are incompatible with an artistic work.
6) There are numerous bloodstains on the forehead and on the skull: the traditional representation of Jesus has always been with a crown of thorns while the wounds on the Shroud presuppose a helmet of thorns, an unknown fact until recent times. Once again, no counterfeiter would have had reasons to contradict the traditional representation out of the blue.
7) The body image is absent in some places such as the right part of the face and forehead and other parts of the body: only recently has the reason explained that it is connected to the ritual formalities of the burial.
8) The body image contains three-dimensional information: the paintings and photos are generally flat and, apart from the technical difficulties of reproduction, the reasons that may have led the hypothetical forger to create such an unnecessary and unknown effect are not explained. in the history of art.
9) The body image is extremely superficial and consists of sepia-colored fibrils which are oxidized and dehydrated: for known ancient chemical and physical techniques it would not have been possible, while there is a compatible modern optoelectronic technique.

It is deduced, therefore, that "the Shroud is not a fake, much less medieval, and actually contained the dead body of a man crucified in ancient times".

The other hypothesis is that the Shroud contained a body of a stranger, not that of Jesus, who was also crucified in the same way more or less at the same time. A thesis once again unreasonable, because:

1) The funeral sheet used to wrap the corpse was precious and expensive: similar linens were used in Israel only for people of real rank and / or high social position, and in this case history would have talked about it.
2) The man of the Shroud was methodically flogged on the whole surface of the body: there are evident signs of Roman scourge in such a large number that, apart from the Gospels, no historical document has ever reported them for any other condemned.
3) The man of the Shroud was crowned with a crown / helmet of thorns: there are evident signs of the wounds of the thorns and no other crucifixions occurred with this singular addition historically.
4) The side has been pierced by a spear: there is a showy stain of blood and serum in the right side of the man caused by a spear wound, a rather irrelevant fact.
5) The legs of the man of the Shroud are intact, while those of those sentenced to crucifixion were generally broken to hasten his death, which would have occurred only much later due to suffocation.
6) The Shroud does not contain traces of putrescent liquids and gases: these signs are produced after about 40 hours from death, and therefore the body was no longer there before then but not too much earlier, due to the blood stains that have it took some time to form for the liquefaction of the already coagulated blood, hemolysis process.
7) The body has not been removed manually: there are no traces of entrainment at the blood spots.

According to the false hypothesis, it should be assumed that «another person was subjected to the same tortures as the Jesus described by the Gospels, bearing in mind however that no one at the time knew the consequences of such actions, and that it would have been practically impossible to reproduce the same temporal and spatial conditions ". The most logical explanation is that "the Shroud was actually the sheet used to cover the corpse of Jesus about 2.000 years ago, after being scourged and crucified in a city in Galilee called Jerusalem, as was described in the canonical Gospels".
