Also, one thing has always puzzled me, if the body were lying down I would not expect the hair to be framing the face as shown, it would have fallen back.

Tests on living persons and cadavers have shown that with the "napkin bound about his head" (under the jaw and around the head by the ears) the long hair exhibits EXACTLY that pattern... it is supported by the rolled up napkin (othonia). This is especially true if the hair is (as in this case) matted and stiff with blood and sweat.

I went back and looked at the photos again and the hair appears to continue down past the chin line, so I don't see how that portion of the hair would have stayed in place even if it were stiff.
