Robert Langdon Series by Dan Brown

Author: Dan Brown

Robert Langdon is a fictional protagonist of a series of novels, novellas and short stories by American author Dan Brown. A Harvard University professor of religious iconology and symbology (a fictional field related to the study of historic symbols, which is not methodologically connected to the actual discipline of semiotics). Brown's novels that feature the lead character Robert Langdon also include historical themes and Christianity as motifs, and as a result, have generated controversy. Brown states on his website that his books are not anti-Christian, though he is on a 'constant spiritual journey' himself, and says that his book The Da Vinci Code is simply "an entertaining story that promotes spiritual discussion and debate" and suggests that the book may be used "as a positive catalyst for introspection and exploration of our faith."
