Photography of the shroud by Secondo Pia in 1898 indicated that the image resembled a photographic 'negative' and represents the first modern study.
Subsequently the shroud was made available for scientific examination, first in 19 by a committee appointed by Cardinal Michele Pellegrino .
The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.
The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.
The Vatican, tiptoeing carefully, has never claimed that the 14-foot linen cloth was, as some believers claim, used to cover Christ after he was taken from the cross 2,000 years ago.
Despite numerous investigations and tests, the status of the Shroud of Turin remains murky, and the nature of the image and how it was fixed on the cloth remain puzzling.

As Controls, three samples whose ages had been determined independently were also dated.
Slide Show: The Shroud of Turin Through History The Shroud of Turin, the controversial piece of linen that some believe to be the burial cloth of Jesus Christ, could finally be dated accurately.
A new method "stands to revolutionize radiocarbon dating," according to research presented on Tuesday at the National Meeting of the American Chemical Society (ACS) in San Francisco.
