Voice of Reason: Exposing the Da Vinci Hoax

The record bestseller, Dan Brown's 2004 The Da Vinci Code, has renewed interest in the quest for the Holy Grail, restyling the medieval legend for a public that often gorges itself on a diet of pseudoscience, pseudo-history, and fantasy.

Unfortunately, the book is largely based on obscure, forged documents that have now deceived millions.

The adventure tale begins with Paris police summoning Robert Langdon, an Indiana Jones type, to the Louvre to view the corpse of curator Jacques Saunier. Saunier has been murdered in bizarre circumstances. Soon Langdon and beautiful cryptanalyst Sophie Neveau lead readers on a page-turning treasure hunt across France and England, propelled by a series of puzzles and clues. Along the way, the pair search for a hidden "truth" that challenges mainstream Christianity. Brown drew heavily on the 1982 bestseller, Holy Blood, Holy Grail, written by Michael Baigent, Richard Leigh, and Henry Lincoln (1996), with Lincoln as the conceptual author.

Brown's novel is predicated on a conspiracy theory involving Jesus and Mary Magdalene. Supposedly the old French word sangreal is explained not as san greal ("holy grail") but as sang real ("royal blood"). Although that concept was not current before the late Middle Ages, Holy Blood, Holy Grail argues that Jesus was married to Mary Magdalene, with whom he had a child, and even that he may have survived the Crucifixion. Jesus' child, so the "non-fiction" book claims, thus began a bloodline that led to the Merovingian dynasty, a succession of kings who ruled what is today France from 481 to 751.

Brown seizes on Leonardo--borrowing from "The Secret Code of Leonardo Da Vinci," chapter one of another work of pseudo-history titled "The Templar Revelation." This was co-authored by "researchers" Lynn Picknett and Clive Prince, whose previous foray into nonsense was their claim that Leonardo had created the Shroud of Turin--even though that forgery appeared nearly a century before the great artist and inventive genius was born!

Among the "revelations" of Picknett and Prince, adopted by Dan Brown in The Da Vinci Code, is the claim that Leonardo's fresco, Last Supper, contains hidden symbolism relating to the sang real secret. They claim, for instance, that St. John in the picture (seated at the right of Jesus) is actually a woman--Mary Magdalene!--and that the shape made by "Mary" and Jesus is "a giant, spreadeagled 'M,'" supposedly confirming the interpretation. By repeating this silliness, Brown provokes critics to note that his characterizations reveal ignorance about his subject.

Of course, Dan Brown--with the authors of Holy Blood, Holy Grail and The Templar Revelation--was also duped by the Priory of Sion hoax, which he in turn foisted onto his readers. But he is apparently unrepentant, and his apologists point out that The Da Vinci Code is, after all, fiction, although at the beginning of the novel, Brown claimed it was based on fact. Meanwhile, despite the devastatingly negative evidence, The Da Vinci Code mania continues. Perhaps Brown should go on his own quest--for the truth.
