<DIV><DIV>With its superlative stone carvings and strong Templar and Freemasonic connections, Rosslyn Chapel—a 15th-century Gothic masterpiece that appeared in <I>The Da Vinci Code</I>—represents an absorbing historical puzzle. Alan Butler and John Ritchie believe that its walls once sheltered a holy relic: the skull of St Matthew. They lay out their startling evidence, complete with formerly unpublished images, and embark on an unprecedented exploration of the Chapel's history, as a Christian church and as something more: a reconstruction of King Solomon's Temple and an astronomical observatory.</DIV><DIV><BR> </DIV></DIV>
