The Shroud of Turin (or Turin Shroud) is an ancient linen cloth bearing the image of a man who appears to have been physically traumatized in a manner consistent with crucifixion. The image can not be seen on the shroud with the naked eye and for several centuries the shroud had been displayed without it. The image was first observed in 1989 on the reverse photographic plate when amateur photographer Secondo Pia was unexpectedly allowed to photograph it. Some believe it is the cloth that covered Jesus when he was placed in his tomb. Skeptics contend the shroud is a medieval hoax or forgery.
