: The carbon dating, which as you know occurred after the STURP research concluded nearly 30 years ago, is alone enough to impeach that effort. The fact that the shroud-faithful are in denial and carping about the dates from fabric provided by the church doesn't cut any ice. People still trump up "evidence" that there was no moon landing, that God created the world in October of 4004 BC, etc. 

 : I of course will not respond as you demand about direct contact time.  Your demand in fact shows your bias.  The current author asserts that the "shroud" has an anatomically impossible image on it in the following easily visible ways: 
 :* the head is misproportioned, both from normal and from the body 
 :* one forearm is significantly longer than the other 
 :* the posture of the body is also impossible 

 : If you'll just open your own eyes, you'll be able to see that the "shroud" matches the painting style of its day, rather than accurately rendering a human form. 

 : The shroud article, as well as ancillary supporting articles violate NPOV under the guise of adhering to it.  Their specific failing is Npov#Giving_.22equal_validity.22.
