Father Z posted a link yesterday to a news story about some Italian scientists who claim to have successfully replicated the image on the Holy Shroud of Turin using materials available to medieval artists. I did some digging around and found the negative image they had produced. Despite some obvious criticisms one could make- the image is relatively crude, blood imaging is superimposed on the "body" image etc., I feel I have to agree that this appears to be the most plausible attempt yet made. One thing the experiment demonstrates quite clearly is the likelihood of the original image resulting from contact with a real human body. Significantly, in neither case, is there any obvious distortion of the kind one might expect to result from the "contact printing" process. Nevertheless, while the question of the relationship of "blood" and "body" images by no means rules out the possibility of its being a forgery I am still not persuaded. Some indication of my reasoning may be found here.
