Colin has an interesting piece on his blog. Unfortunately due to his unconventional way of posting, what should have been, by itself, a posting is an unrelated addendum to a different topic. You will need to go to his posting, Might John P.Jackson have been right in thinking the frontal and dorsal images of the Man on the Turin Shroud are subtly different? Different imprinting configurations ("LOTTO" v "LUWU")? and scroll down, way-way down, until you see a picture of a man and his wife.
What does Colin see that is 3D in this? He asked the question, not me. He doesn’t answer. He shows us a picture but I see nothing. Am I supposed to?
Purpose of exercise: medieval (and modern folk too) are quite happy to take their brass rubbings, and see them for what they are – negative replicas that have an unusual quality, no longer life-like, but interestingly different. Few if any will feel a need to do what I have just done, using 20th/21st century technology, simply to get more life-like images of the original subjects.
Could have fooled me. . . but I had my morning coffee. CLICK HERE to see quite a few brass rubbings, both negative and positive.
