There is an article on www.bbc.co.uk/news/magazine-33164668 today about the Turin shroud, an interesting medieval icon.
I don't understand, if, as some claim, it is genuinely the shroud in which Jesus was wrapped when taken down from the cross, how come the image on it is two-dimensional, not three-dimensional. Surely the parts touching at the sides of the face and body would be marked, not just the front and back like a photograph?
It seems more likely to me that someone was experimenting with making an image using silver nitrate (which was known about then) and the result was taken up enthusiastically by a seller of "bits of the true cross" and similar relics.
