Leonardo was fascinated with faces and was known to follow people around town to sketch them. He likely sketched hundreds (if not thousands) of faces. With a log of sketches like that is it believable that he needed to use his own face twice in the Last Supper painting?
I don’t really know much of the specifics about Da Vinci. I did d/l “The Notebooks of ...[LDV]” from Gutenberg a few months ago, but haven’t gotten around to reading it yet.
I was just thinking. It's a wall painting, It's deteriorated over the centuries, and has been repaired a number of times.
My point being that the faces are no longer what Da Vinci created.
From Wiki:
This restoration [most recent] took 21 years and on May 28, 1999 the painting was put back on display, ... When it was unveiled, considerable controversy was aroused by the dramatic changes in colours, tones, and even some facial shapes.
