In 1977, American scientists Eric Jumper and John Jackson processed electronically a negative photographic image of the shroud and discovered that it produces a three-dimensional image, a feature that is not possessed by normal paintings or photographs. According to the tests, the shroud dates back between 1260 and 1390. But the form chosen for the tests caused a lot of debate, and the problem is still open today. These days, no other tests are in progress. But the results obtained earlier indicate that the human image on the shroud isn't necessarily a painting.
Most scientists agree the image was produced by an oxidation-dehydration of the cellulose fibers.
In their 1997 book The Second Messiah Christopher Knight and Robert Lomas claim it's the body of Jacques de Molay, who died in 1307. They say the Catholic Church should allow new tests.
