The Shroud of Turin or Turin Shroud (Italian: Sindone di Torino) is a length of linen cloth bearing the image of a man who appears to have suffered physical trauma in a manner consistent with crucifixion. There is no consensus yet on how the image was created. It is believed by some to be the burial shroud of Jesus of Nazareth, despite radiocarbon dating tests from 1988 dating it to the Medieval period. The image is much clearer in black-and-white negative than in its natural sepia color. The negative image was first observed in 1898 on the reverse photographic plate of amateur photographer Secondo Pia, who was allowed to photograph it while it was being exhibited in the Turin Cathedral.
