At the risk of bringing the Turin Shroud into this thread, does anyone else think the body proportions are all extremely strange?
Have a good look at the image below and try and replicate the posture. You'll find that unless you have Orang-Utan ancestry or hunch yourself right over your arms are not long enough to cover your nether regions in the manner depicted in the image. The arms appear to have been elongated to cover the private parts of the person depicted. The left hand appears to be stretched and the face and head very thin and a little small. Also is it not also odd that the face depicts the classic image style that is ingrained on us?
I expect there were a few dozen of these variable-quality shrouds knocking around Europe in the 14th century. Doubtless monasteries charged for a quick glance to the pious plebian peasants - they would have been a nice little earner. The Shroud of Turin is probably the most notorious survivor of a medieval lucrative trade in relic-viewing.
