Fans of the movie are well advised to read
the novel. Just like some other novels turned into movies, there are delicious details of the novel that have been adjusted, if not deleted, for the movie: Bernard Gui did not die by falling on one of his torture machines; the girl was eventually burned at the stake; William was not able to save any of the books; the abbey-burning scene was more horrific than as shown in the movie; there was that melancholic scene at the ending of the novel where Adso went back to the ruins of the Abbey years later in one of his return trips to Italy from his Abbey in Melk. He was able to collect bits of burnt parchments he kept as souvenirs. Reading it could be tedious though; almost like reading a research material from the Vatican Secret Archives. Well, consider this on the writer, Umberto Eco, being a scholarly medievalist and a professor of semiotics. There is also
another book on how to get the most from the novel!
