Joe Marino sent along a link to a paper originally presented by François Gazay at the Dallas symposium in 2005. I was there but forgot about the paper until Joe sent me the link. It is quite remarkable. To my way of thinking, this subject has received far too little attention, far to little challenge or verification:
This study suggests that if this Calvary has these remarkable characteristics it is not by chance. The only valid explanation that can [be] advanced is that the sculptor of the Calvary saw the original or an extremely precise copy of the TS « head » very closely and then engraved the various components in the stone of the Calvary.
The representation of Mandylion in the shape of an icon within a landscaped frame similar to the frame of the image of Edessa can be explained only by a precise chronology of the events which made the history of the TS.
In addition, it should be noted that while the Shroud disappeared between 1206 and 1350, a Templar worship of a « magic head » or Baphomet appeared towards 1265. This worship was declared « idolatrous » in 1307 at the time of the arrest of Templars by the King of France Philippe the Beautiful, and was used as the indictment basis for the inquisitors [ the Holy Office during the Trial of the Templars until 1314.
