Back before Dan Brown had becoming the Most Important Human Ever, even before he published Angels and Demons, my wife and I visited Rosslyn Chapel in Roslin Glen, Scotland. While not actually seeking the Holy Grail, I had been doing some research on Celtic lore, ostensibly where the Grail legend originates, and so we made our way to the remote and (then) desolate site of this unusual church. Officially the Collegiate Chapel of St. Matthew, it is, without doubt, the busiest piece of architectural stonework I have ever witnessed. We went for the grail. We stayed for the art.
The research I had been conducting (finally published just last year as a contribution to a Festschrift for Nicolas Wyatt) involved the Mabinogian, a repository of Celtic mythology, and the legend of Bran. For sharing the name of a healthful breakfast cereal, Bran is renowned for also having had a life-restoring cauldron. He even made a journey to the netherworld and his head kept singing even after having been dissociated from his body. An uncommon hero indeed. All historical indicators, however, point to the cauldron as the original of the Holy Grail. Certainly the Bible does not mention it, nor does it appear very early in Christian mythology.
People, as Dan Brown’s financial independence loudly indicates, like a good conspiracy theory. There is a comfort in believing that a magical object of great power is out there somewhere and that a rather ordinary Harvard professor (!) might be able to find it, yet resist taking it. Far truer to life is Indiana Jones and the Final Crusade; people feel the need to touch, to control the power beyond themselves. Even at the cost of their lives. Despite the fact that the Grail is a fiction, it simply will not disappear — although no one can find it and it has never been seen. Faith tends not to be based on tangibles. This is attested every time Dan Brown makes his way to the bank and the population reads with wonder about meanings that simply don’t exist.
