Beyond the Da Vinci Code: From the Rose Line to the Bloodline : The truth behind a work of fiction that incited a movement to disprove it. As controversial as it was popular, The Da Vinci Code sparked an intrigue that spanned religious, cultural, mathematical and literary domains. Was Jesus married? Did Leonardo da Vinci bury âcluesâ to the truth of the bloodline in his art? Is there a secret organization that protects the whereabouts of the Holy Grail? Proving that a number of the novel's most radical claims are historically sound, and exposing the spurious nature of others, Sangeet Duchane compares the early and modern Church, analyzes Dan Brown's use of symbols, explores origins of the Grail myth, and ends with a tour through the significant locales of the novel as well as a reflection on the reasons it has touched so many and the meaning of modern myth.
