from the sarcophagus of Pierre de Corneillan? 

Artist Paul Gell, aka Shroud Solver, writes by way of a comment:

Hello, my name is paul gell, and i have discovered a bas relief match to the shroud of turin! Im trying to get the academic community to notice and investigate my find. I created a 45 minute presentation, and a 5 minute summary. Ive placed my videos on a facebook page i created called “shroud solver”. The videos are also on youtube. Any comments or suggestions on how i am supposed to get real scholars involved would be appreciated! Thanks! Paul Gell

I went looking and found these four videos. Comments?
