In the debate about the Shroud of Turin
, perhaps the strongest argument that the pro-Shroud side had going for it was that no one could figure out how a medieval forger could have created such a thing. How could the forger have etched a three-dimensional photo-negative image of a crucified man onto a piece of linen? Nathan Wilson has pretty much demolished this pro-shroud argument by showing that it would have been quite easy for a medieval forger to have done this. All he (or she, but probably he) would have needed is some white paint, a large piece of glass, and a piece of linen. You paint a figure of a man on the glass, place the glass over the linen, and leave it out in the sun for a couple of days. The sun then bleaches the material, thereby transferring a three-dimensional photo-negative image of whatever was painted on the glass onto the linen. It's one of those things that seems so obvious when you think about it, and answers so many questions about the shroud, that it has to be the solution. And yet it's taken centuries for someone to figure it out. Wilson has a great (and quite detailed) article in Christianity Today
explaining how he went about solving the mystery. There's also a shorter article about Wilson's 'shadow shroud' on discovery.com
