It's worth noting that the Shroud of Turin did not attract much attention around the world until the end of the 19th century. The reason for this is simple: the Shroud itself did not seem to be all that spectacular -- it was an ancient piece of fabric with what appeared to be the image of a man on it.

What changed all of this was the advent of photography. An Italian photographer named Secondo Pia received permission to photograph the Shroud during one of its rare public displays, and while he was developing the film he produced a negative that had far more detail than the original image (the image you see at the top of this thread is the negative, not the original).

The implication of this was immediately clear to Pia: The "negative" he was looking at was actually the real image, and the "original" image on the Shroud was actually the negative -- which meant that whatever process was used to produce that image was identical to a photographic process that the world had only discovered recently!

"Identical" may be an overstatement. How about similar?
