It seems to me that if the floor was made of mirrors, the picking up the skirt bit was unnecessary. He could have just looked anyway.
The deformed foot angle is interesting, that has been mentioned earlier in the thread. A lot of kings had deformed legs or feet didnt they? I think Odysseus, among others? I ssem to remember some Robert Graves theory about this, he reckoned Jesus had a bad leg or something. It was to do with ritual maiming of the heir apparent for some puropse or other. I think perhaps to do with the maiming of smiths by tribes in the Iron Age.
