What exactly is the famous Shroud of Turin? Archaeologist Shimon Gibson,  a senior research fellow at the  W.P. Albright Institute of Archaeological Research in Jerusalem, recently conducted a major study on a radiocarbon-dated 1st century B.C. burial shroud he and his colleagues excavated in a Jerusalem tomb.  This funerary cloth was  made very differently  from the  Shroud of Turin,  casting yet more cold water on the authenticity of the famous relic.  For more on this,  see my blog post today at Archaeology magazine.
