A staggeringly popular work of fiction, Dan Brown's The Da Vinci Code has sold in its millions. But this fast-paced mystery is unusual in that the author states up front that the historical information in the book is all factually accurate. But is this claim true?

Did Emperor Constantine select for the New Testament - from some eighty contending Gospels - the only four that stressed that Jesus was divine? And did Christ really marry Mary Magdalene?
