Frei, who once pronounced the forged "Hitler Diaries" to be genuine, probably introduced the pollen grains himself or was duped and innocently picked up pollen grains another pious fraud had introduced (Nickell).
The shroud is a 14th century painting, not a 2000-year-old cloth with Jesus's image.
Mc Crone's theory is that "a male model was daubed with paint and wrapped in the sheet to create the shadowy figure of Jesus." The model was covered in red ochre, "a pigment found in earth and widely used in Italy during the Middle Ages, and pressed his forehead, cheekbones and other parts of his head and body on to the linen to create the image that exists today.
"All empirical evidence and logical reasoning concerning the shroud of Turin will lead any objective, rational person to the firm conclusion that the shroud is an artifact created by an artist in the fourteenth-century."The "shroud" of Turin is a woven cloth about 14 feet long and 3.5 feet wide with an image of a man on it.
Actually, it has two images, one frontal and one rear, with the heads meeting in the middle.
But, since there is no blood on the shroud of Turin and there is no good reason to accept Danin's assumption that the pollen grains were on the Shroud from its origin, this argument is spurious.
In any case, the fact that pollen grains found near the Dead Sea or Jerusalem were on the shroud means little.
Some have noted that the head is 5% too large for its body, the nose is disproportionate, and the arms are too long. In any case, the image is believed by many to be a negative image of the crucified Jesus and the shroud is believed to be his burial shroud. Apparently, the first historical mention of the shroud as the "shroud of Turin" is in the late 16th century when it was brought to the cathedral in that city, though it was allegedly discovered in Turkey during one of the so-called "Holy" Crusades in the so-called "Middle" Ages.
Most skeptics think the image is not a burial shroud, but a painting and a pious hoax. In 1988, the Vatican allowed the shroud to be dated by three independent sources--Oxford University, the University of Arizona, and the Swiss Federal Institute of Technology--and each of them dated the cloth as originating in medieval times, around 1350.
Since the Sudarium is believed to have existed before the 8th century, according to Danin, there is "clear evidence that the shroud originated before the eighth century." The cloth is believed to have been in a chest of relics from at least the time of the Moorish invasion of Spain.
It is said to have been in the chest when it was opened in 1075.
Avinoam Danin, a botanist from Hebrew University of Jerusalem claims he has identified pollen from the tumbleweed Gundelia tournefortii and a bean caper on the shroud.
