Actually, from the Shroud, it appears that his nose may have been broken.
Actually, from the Shroud, viewed as it actually exists, in a “folded over the head with both ends at the feet” panoramic, it appears that the man depicted has a two-dimensional head.
Look at full-length photos of the whole thing, not a cropped and flipped side-by-side view, and you’ll see that the man in the cloth’s forehead seems to touch the back of his head. The shroud’s subject’s skull has no crown. The shroud was folded lengthwise over the body, starting under the heels, running up the back, flipped over the crown of the head, and spread down over the face and anterior torso to the toes, but either about 4 inches of cloth are missing from the center of the fold, or the “Jesus” shown had a skull shaped somewhat like a transversely-peaked roof.
