The Rosslyn Motet emanates from the crypt as you walk into the chapel. It's playing from a modest little boom box, but the acoustics of the underground chambers are so magnificent that you can hear it clearly from anywhere inside. The already solemn tones sound especially ghostly when the chapel is deserted and you can see your breath, even under the heat lamps.
In the five years since the Mitchells announced to the world that they had solved the Rosslyn code, they've received modest recognition in the media and respectable sales of a professional recording of the work. They shrewdly timed their announcement of the solution to the release of the movie adaptation of The Da Vinci Code, giving reporters and producers a ready-made news peg. Over time, however, their story has faded to a curiosity. Interest in whether it is real has waned.
Stuart and Tommy Mitchell say they don't much care if people believe them. On my last day in Roslin, I met Stuart and his friend Ian Robertson at the chapel. Robertson and his co-author Mark Oxbrow wrote by far the best modern book on Rosslyn Chapel, Rosslyn and the Grail. Mostly, Robertson and Oxbrow debunk the various rumors and legends that have attached themselves to the chapel, including the crazy ones about the Holy Grail and Jesus' head. But when it comes to the Rosslyn Motet, they're more circumspect. "One 'code' that may actually exist within Rosslyn," Robertson and Oxbrow write, "is the mysterious carved cubes that ornament some of the arches in the chapel."
