He painted a 3D image?
No one really knows how he did it but the best guess is an early form of photography. Being that it was made to fool people in the first place there are no records of its creation. Fake religious icons were big money makers for local churches.
As to 3D you must consider the simple fact that if the shroud was placed on a body that the entire image would be “three times wider” as you must account for the space present on the SIDES of the body. The image on the shroud is simply far, far too skinny.
Also look at the full image of the shroud and look at the space between the face and the back of the head. Now mentally wrap it around a human head. If this was a real shroud then Jeasus would be about one inch thick from front to back.
So you are saying DaVinci invented photography? This has already been disproven.
