For centuries, the Shroud of Turin has puzzled its critics and advocates. But in the last three decades, examination of the Shroud has revealed even more complexities: a three-dimensional image which no one has been able to explain or duplicate with medieval methods - until now. In this lecture, Nathan Wilson demonstrates how medieval forgers could have easily created a photo negative image of a man, three-dimensionally encoded on linen, by using only painted glass and sunlight. Mr. Wilson also gives an entertaining overview of the Shroud's history, its controversies, and its most ardent defenders and detractors.
