From Italy's Corriere della Sera newspaper.
"il primo negativo "fotografico" della storia che ha come matrice un'immagine mentale»
«Così Leonardo creò la Sindone»
La tesi della scrittrice Vittoria Haziel: «Il maestro usò un ferro arroventato e disegnò sulla tela il suo autoritratto»
Interesting for us photographers.
This is not all. I just finished reading, the "Secret Supper" where Leonardo wa purported to be a Cathar a.d the case is made about the symbolysm in his Last Supper. Very interesting book. No matter what anyone says, the Image of John the Baptist is a woman. Some allege that it's actually Mary Magdalene. Go figure.
