Langdon is granted access to the Vatican Archives where he believes a document containing the clues to the Path of Illumination is located. The clues to the Illuminati markers are placed inside Galileo's famous book called 'Diagramma.' Langdon then sets off on the Path of Illumination in hopes of saving the preferiti and recovering the antimatter canister.
