Paul Vignon (1865-1943) was a French Professor of Biology [5] and an artist [6]. He discovered there were twenty unique features of the Shroud that were found in these depictions of Christ from the sixth century onwards [7]. But Wilson reduced these to a more definite fifteen. [8] Some of these features are merely wrinkles and imperfections of the fabric of the Shroud and artistically make no sense. [9] Yet the artists slavishly copied these features found on the Shroud, including the imperfections. [10]
