The Da Vinci Code is a mystery/detective novel by American author Dan Brown, published in 2003 by Doubleday Fiction. It is a worldwide bestseller with more than 60.5 million copies in print (as of May 2006) and has been translated into 44 languages. Combining the detective, thriller and conspiracy fiction genres, the book is part two of a trilogy that started with Brown's 2000 novel Angels and Demons, which introduced the character Robert Langdon. In November 2004, Random House published a "Special Illustrated Edition", with 160 illustrations interspersed with the text.
The plot of the novel involves a conspiracy by the Catholic Church to cover up the "true" story of Jesus. In the book, the Vatican knows it is living a lie but continues to do so to keep itself in power. The novel has helped generate popular interest in speculation concerning the Holy Grail legend and the role of Mary Magdalene in the history of Christianity. Fans have lauded the book as creative, action-packed and thought-provoking. Critics have attacked it as poorly written, inaccurate and creating confusion between speculation and fact. From a religious point of view, some critics consider it sacrilegious, and decry the many negative implications about the Catholic Church and Opus Dei.
Dan Brown's novel was a smash hit in 2003, even rivaling the sales of the highly popular Harry Potter series. [citation needed] It spawned a number of offspring books and drew glowing reviews from the New York Times, People Magazine and the Washington Post [1]. It also re-ignited interest in the history of the Catholic Church. As well as re-invigorating interest in the church, The Da Vinci Code has also spawned numerous "knockoffs" (as they are referred to by Publishers Weekly) [2], or novels that have a striking resemblance to The Da Vinci Code, including Raymond Khoury's The Last Templar, and The Templar Legacy by Steve Berry.
Sony's Columbia Pictures has adapted the novel to film, with a screenplay written by Akiva Goldsman, and Academy Award winner Ron Howard directing. The film was released on May 18, 2006, and stars Tom Hanks as Robert Langdon, Audrey Tautou as Sophie Neveu, and Sir Ian McKellen as Leigh Teabing. The Da Vinci Code has also inspired webquests.
The Holy Blood and the Holy Grail (retitled Holy Blood, Holy Grail in the United States) is a controversial book by Michael Baigent, Richard Leigh, and Henry Lincoln, which was based in large part on Pierre Plantard's Priory of Sion secret society.
The book was first published in 1982 by Jonathan Cape in London. The book was a follow up of a BBC TV documentary. There was a sequel to the book called The Messianic Legacy, in 1987. It was reissued in an illustrated hardcover version in 2005. One of the books, according to the authors, which influenced the project was L'Or de Rennes (later re-published as Le Trésor Maudit), a 1967 book by Gérard de Sède.
In summary, the authors argue that there is evidence that Jesus married Mary Magdalene, had one or more children, and that those children or their descendents emigrated to what is now southern France. Once there, they intermarried with the noble families that would eventually become the Merovingian dynasty, which is championed today by a secret society called the Priory of Sion.
An international bestseller upon its release, The Holy Blood and the Holy Grail spurred interest in a number of ideas related to its central thesis. Response from mainstream historians and academics, however, was nearly universally negative. Critics argued that the bulk of the claims, ancient mysteries and conspiracy theories presented as fact, are pseudohistorical.
