''The Name of the Rose'' (''Il nome della rosa'') is a novel written by Creator/UmbertoEco in 1980, which also received a [[TheFilmOfTheBook movie adaptation]] in 1986, directed by Jean-Jacques Annaud, and starring Creator/ChristianSlater, Creator/FMurrayAbraham, Creator/RonPerlman, Creator/MichaelLonsdale, and Creator/SeanConnery. It was also adapted a year later into an unlicensed [[https://en.wikipedia.org/wiki/La_Abadía_del_Crimen videogame]].

It is set in what has been called the [[MedievalMorons disastrous]] [[TheLateMiddleAges fourteenth century]], during the period of the Medieval Inquisition. The story, described by some as Literature/SherlockHolmes [[RecycledINSPACE IN THE 14th CENTURY]], follows Brother William of Baskerville and his young friar apprentice, Adso of [[UsefulNotes/{{Austria}} Melk]], who go to an abbey where a murder was committed in order to [[DetectiveStory investigate]].

!!Tropes used include:
%% Zero context examples have been commented out. Please provide context before uncommenting.
* AdaptationDistillation: The book is a detective mystery interwoven with 500 pages of incredible detail of the religious and political schism in the church that is nearly inscrutable to anyone without a post-graduate degree in Theology and 14th Century Political History. (Or, reasonably arguably, anyone but Creator/UmbertoEco.) The movie drops most of the Theology, History and Politics in favor of the detective story.
* AdaptedOut: The Swedish monk Benno of Uppsala was cut from the film.
* AndAnotherThing: Realising the Abbot has something on his mind, William waits till the Abbot is leaving before asking him about the freshly dug grave outside. It breaks through his reluctance enough to get him talking.
* AuthorAppeal: InUniverse, Adso mentions his love of TheLongList (and it shows throughout the book).
* ArtisticLicenseHistory: Pretty much the only thing the film version gets right about the historical Bernardo Gui is that he was an Inquisitor during the fourteenth century. While Gui did convict large numbers of heretics during his tenure, only about five percent of them were executed; he far preferred to prove heresies wrong and to reconcile heretics with the church rather than kill them, and he was always more scholar and administrator than zealot and crusader. He's less of a cackling arch-villain in the novel, but not by much. Neither he nor the Inquisition accused people of witchcraft either, for at the time the Church officially disbelieved it existed. Even later, the Inquisitions dealt mainly with heresy.
%% * AwesomenessByAnalysis: William.
* BeAsUnhelpfulAsPossible: This is the attitude of every monk in the abbey toward William's investigation.
* BigBadEnsemble: The SerialKiller [[spoiler:Jorge]] who causes the whole book's manhunt and the sinister Inquisitor Bernando Gui who doesn't really contribute anything to the manhunt other than providing scapegoats and unlike the killer he murders in official and socially acceptable ways, so he doesn't need to hide both in-universe and as far as spoilers are concerned.
%%* BigLabyrinthineBuilding
* BlackAndWhiteInsanity: A caliph is mentioned as having ordered a library burned because either they said what was in the Quran and therefore redundant, or did ''not'' say what was in the Quran and thus heretical.
* TheBlackDeath: At the end of the novel, Adso reveals that William eventually died during the Black Death.
* BlindWithoutEm: {{Downplayed}}. While William can see perfectly well without his spectacles, he is unable to read small text without them. This costs him precious time that results in ever more murders.
%%* BookcasePassage: And tomb passage, too.
* BrickJoke: Novel only. In what seems to be another example of DidDoTheResearch, William discusses an Arabic treatise on hydrophobia (rabies) in dogs in passing. It comes up again during the [[spoiler: trial of the cellarer]] when William claims this is what he was discussing with a murdered monk, going into great detail about how the text describes the twenty-five symptoms of hydrophobia, with which Bernardo Gui is surely familiar. This swipe is a pun on Gui's order, the Dominicans- "domine canes", God's dogs.
* BurnTheWitch: In the film, Brother Salvatore and Brother Remigio are burned at the stake as scapegoats by Father Bernardo Gui, leader of the Inquisition. Gui also tries to burn a local peasant girl, but [[SparedByAdaptation in the film she is rescued]] by [[TheRevolutionWillNotBeCivilized rebellious peasants]] who manage to kill Gui in the resulting chaos. In the book, Gui has the three transported away, and all three of them are executed elsewhere.
* CampGay: Brother Berengar.
* CelibateHero:
** As a Franciscan friar, William is sworn to celibacy.
** Adso is supposed to be this. [[spoiler:He fails, once in his life.]]
* CelebrityParadox: {{Averted}}. Does William of Occam exist in this version? Yes, he's a friend of William of Baskerville.
* CharacterExaggeration: In the film, the transmogrification of the [[PuritySue saintly]] Ubertino da Casale (a minor character) from a well-educated, decent, pious (if slightly fanatical) old man to a [[MadOracle creepy]], [[CrypticConversation obtuse]] ButtMonkey who hits on Adso and is ridiculed by William. Note that the poor guy actually existed.
* CloudCuckooLander: Several, notably the [[MadOracle eccentric]] Ubertino da Casale ''(film only)'', and the deformed Salvatore.
* ColdBloodedTorture: Bernardo Gui plans to use it on the cellarer, but even the mention of torture is enough for him to admit everything, even things he didn't commit.
* CoolOldGuy: William, played by Creator/SeanConnery.
%%* CorruptChurch: The papal delegates.
* CoverInnocentEyesAndEars: When Bernado Gui catches the peasant girl inside the monastery, he rips open her clothes to expose her breasts, causing the monks to avert their gaze in horror or cover their eyes. One monk does both, covering an eye and closing the other, [[CovertPervert which he quickly opens again for a peek]].
* CrypticConversation: Salvatore, Ubertino da Casale, and [[BeAsUnhelpfulAsPossible half the monks]].
* DatedHistory: The final sentence of the book (seen at the top of this page) is a quote from 12th century monk Bernard of Cluny. However, while a few of his manuscripts do say "rosa", based on the relative quality of the various texts the modern consensus is that Bernard actually wrote "Roma", as in the city of Rome, which got lost in transcription. Eco has since admitted he wasn't aware of this.
* DeadlyBook: The novel revolves around a book that apparently contains ThingsManWasNotMeantToKnow; anybody who reads it dies horribly shortly afterward. [[spoiler:It turns out that there's nothing mystical about the book itself, but someone has treated its pages with poison to kill off anyone who reads it and prevent its contents getting about.]]
%%* DefinitelyFinalDungeon: The library tower.
* DescriptionPorn: The book devotes page upon page to descriptions of the church's altar, the entrance to the crypt, Adso's vivid [[spoiler: psychedelic-herb-induced]] visions, and the monastery's relics.
* DestroyTheEvidence: William brings all the evidence he's discovered so far to the Abbot, including a note found by one of the victims revealing the location of the forbidden book. The Abbot informs him the Inquisition is already on the way, then burns the note. Fortunately William was GenreSavvy enough to make a copy.
* DeliberateValuesDissonance: Religious wars declared over whether or not the clergy should be poor, homosexuality being a crime punishable by death, treating other religions (and diferent subsets of the same religion) with unmasked contempt... Welcome to medieval Europe.
* DirectLineToTheAuthor: In a prologue, Eco describes how he "found" Adso's manuscript in the 1960s.
* DownerEnding:[[spoiler: Jorge is never bought to justice, the library burns down and kills what few named characters there are left, and William dies not long after the events of the story.]]
* DueToTheDead: A killer rather hypocritically gives the last rites to the herbalist in the movie.
* TheDungAges: This is how the monastery is portrayed in the movie; moreso the hovel outside its walls, where the peasant girl lives.
* EatTheEvidence: Which in this case also qualifies as [[spoiler: [[CyanidePill suicide]]]].
* EekAMouse: The monks laugh when Berenger does the 'jump up on the chair' version.
* EurekaMoment:
** William has one considering the secret of the library. Adso remembers how Salvatore said "tertius equi", which is CanisLatinicus for "The third of horse" (when he meant "the third horse"). William concludes: "the first and the seventh of the four" really means [[spoiler:"the first and the seventh of the ''word'' four", and "four" is "quatuor" in Latin, so you have to push the letters Q and R!]]
** They had a minor one earlier, when Adso dreamed a story similar to the "Coena Cypriani", a kind of [[Literature/TheBible Bible]] {{parody}}, which helps William to remember that there was a book in the library consisting of four texts, one of them a comment for the Coena Cypriani, another one the book they're looking for.
* EveryManHasHisPrice: Bence of Upsalla is eager to help William with his investigation... until Malachy makes him the new assistant librarian. His ambition fulfilled, he refuses to help any further.
* EvilHasABadSenseOfHumor: To the extent that it is fundamental to the plot. [[spoiler: The murderer is philosophically opposed to laughter, believing that it causes men to stray from the path of God by diminishing and ridiculing the work of the Devil, and commits his murders to conceal the last edition of a work by Aristotle which praises the importance of laughter. Of course, the murderer [[WellIntentionedExtremist believes he is doing the work of God]], but note that he is the one going around murdering people in horrible ways.]]
* TheExoticDetective: A medieval friar.
* FingerLickingPoison: [[spoiler:The page corners of the book have been coated in arsenic, so anyone turning the pages (often licking their finger to help them) will be poisoned.]]
* FirstPersonPeripheralNarrator: The narrator is an older Adso.
%%* FoeYay: [[invoked]] {{Lampshaded}} by Adso in the book as he follows the last dialogue between [[spoiler: William and Jorge]].
* FriendOrIdolDecision:
** Adso, at the end of the film, chooses to follow his master rather than stay with the girl.
** William has to choose between burning to death to save as many books as he can, or abandoning the library.
* FromBadToWorse: The body count grows by the day...and then the main setting burns to the ground.
* GettingCrapPastTheRadar: At one point, Adso describes how William angrily spits out a one-syllable word in his native language (which is English), and comments that he luckily didn't understand the word, because it sounded very much like it means something naughty...
* {{Gonk}}: The abbot, the Greek translator, and Adelmo are pretty much the only three of the Benedictine monks who are not frightfully ugly. The worst is undoubtedly Creator/RonPerlman's Salvatore, who doesn't even look human.
* GratuitousForeignLanguage: Most of the [[AltumVidetur Latin phrases]] are given translations in the back of the book, but the [[GratuitousGerman Gratuitous Middle High German]] is not.
* TheGrotesque: In the movie, Adso is peering fearfully at some hideous gargoyles when the equally hideous Salvatore lurches at him out of the darkness, babbling nonsense.
%%* TheHeretic
* HistoricalDetectiveFiction: Investigating suspicious deaths in a monastery.
* HistoricalDomainCharacter: Bernard(o) Gui(donis), Ubertino da Casale, Michael of Cesena.
* HistoricalVillainUpgrade: While he might not have been a nice guy, Bernardo Gui was much less melodramatic in RealLife.
* ImpaledWithExtremePrejudice: [[spoiler:Bernardo Gui in the film]]. This didn't happen in the book or in RealLife, in which he died quietly of natural causes (he was also older at the time, about 69 or 70) a couple of years after the time in which the movie takes place.
* ImprovisedWeapon: The herbalist is murdered with an astrolabe. [[spoiler:And the book is poisoned, killing anyone who reads it without a protective glove.]]
* InMyLanguageThatSoundsLike: Adso recounts explaining to a German noble that Italians go through the forest with pigs looking for "tartufo" (truffles), which they dig up and eat. The German heard the keyword as "der Teufel" (the Devil) and gave Adso a very strange look after crossing himself. They both had a good laugh about it afterwards.
* InWhichATropeIsDescribed: Every chapter of the novel begins with a flowery summary of the events that will be told. In the intro, the modern day translator comments that they were likely added by an author from the Enlightenment, since the practice is about four hundred years too early for the time the manuscript was written. One chapter heading is even self-referential, noting how summarizing a plot-heavy chapter in a heading would not be very useful.
%%* KarmaHoudini: [[spoiler: Bernardo Guy]] in the book.
* TheKillerWasLeftHanded: Although not the killer, Berenger is shown to have written a note because he's the only left-handed monk.
%%* KnightTemplar: A whole army of them: the killer, the Dulcinians, the Inquisitors...
* TheLastOfTheseIsNotLikeTheOthers
-->'''Adso:''' ''(narrating)'' [[WhoAreYou Who was she?]] Who was this creature that rose like the dawn, was as bewitching as the moon, radiant as the sun? [[SexIsEvilAndIAmHorny Terrible as an army poised for battle.]]
** Which is, however, a direct quotation of the [[Literature/SongOfSongs Canticles / Song of Songs / Song of Solomon]], the Sixth Chapter, the tenth verse. Here-endeth-the-Lesson.
%%* TheLateMiddleAges
* LockedRoomMystery: The first death involves a defenestration beneath a window that cannot be unopened. William easily proves the man jumped from a nearby tower and his body rolled to its final resting place.
* LooksLikeOrlok: The chief librarian monk.
%%* LitFic
* LoveMakesYouCrazy: Adso reads a book where love is described as a [[OurWerewolvesAreDifferent disease similar to lycanthropy]]. The book certainly gives him pause, given that [[SexEqualsLove he's convinced he's fallen in love with the girl.]]
%%* MadOracle: Ubertino is considered to be this in the film.
* MeaningfulName:
** William of Baskerville. The name is a two-part ShoutOut to logician and friar William of Ockham and [[SherlockHolmes a certain fictional detective.]]
** The blind monk Jorge of Burgos is a shoutout to the (blind) Creator/JorgeLuisBorges, an important literary influence for Eco.
* MedievalMorons: William himself and the sensible [[TheWatson Adso]] make everyone else look fanatical or dumb, at least in the movie. In the novel, many people show a great deal of scholarly knowledge and expertise, but William is about the only one who can escape beyond the stagnated and fundamentalist nature of medieval learning.
* MundaneUtility: William using his SherlockScan to tell Adso where the toilet is located.
* {{Metaphorgotten}}: Adso asks William about some of the schisms within the faith, and William comes up with a metaphor involving a river that divides into a delta. When Adso still doesn't get it, William admits he's not really good at parables and tells him to forget the river.
* MindScrew: How to access the secret room in the library. "The hand over the idol?/image?[[spoiler:/mirror!]] should move (how exactly?) the first and the seventh of the four(???)".
* [[ManOnFire Monk On Fire]]: To ensure the book's destruction, the killer holds it over the flames, but his robe catches on fire as well.
* MotiveRant: [[spoiler: Jorge]] gives one at the end. This is less obvious in the movie, where the BigBad is more reactive and less prone to discussion; most of it is held while the [[VillainTeleportation villain is eluding the heroes]] throughout the library.
%%* MythArc: With other Eco books.
* NiceJobBreakingItHero: [[spoiler: If William hadn't deduced that Jorge was the killer, then sure, Aristotle's book on comedy might have stayed hidden, but on the plus side ''the entire library and every manuscript in it'' wouldn't have burned down.]]
* NoNameGiven: The girl Adso has sex with. He mentions that he couldn't even "lament and call out the belovedís name" (as he read in romances of chivalry) when he learned that she's going to die, because he never learned her name.
* NotMyProblem: Another monk is murdered ''after'' Bernard Gui tortures a false confession out of Remigio. He declares that it's not his job to keep order in the monastery and he already did what he came here to do.
* TheNothingAfterDeath: How Adso imagines the afterlife:
-->I shall soon enter this broad desert, perfectly level and boundless, where the truly pious heart succumbs in bliss. I shall sink into the divine shadow, in a dumb silence and an ineffable union, and in this sinking all equality and all inequality shall be lost, and in that abyss my spirit will lose itself, and will not know the equal or the unequal, or anything else: and all differences will be forgotten. I shall be in the simple foundation, in the silent desert where diversity is never seen, in the privacy where no one finds himself in his proper place. I shall fall into the silent and uninhabited divinity where there is no work and no image.
* NothingButSkulls: Someone with a weird sense of humor decided to order the bones in the crypt: in one place, there are NothingButSkulls, in another one nothing but small bones, and in yet another one nothing but hands. This is a [[ShoutOut reference]] to the [[http://en.wikipedia.org/wiki/Capuchin_Crypt surprisingly real-life Capuchin Crypt.]]
* NubileSavage: The peasant girl is a medieval variation on the theme.
* ObfuscatingDisability: Creator/RonPerlman's version of the deformed, mentally disabled hunchback Salvatore is smarter than he seems. Unfortunately it doesn't work on Bernado, who simply tortures him until he gets the answers he wants.
* OccamsRazor: One of William's tricks of the trade, appropriately enough.
* OminousLatinChanting: In the movie, at least. As expected in an abbey, it happens four times in-universe:
** After the first night, ''Urbs Jerusalem beata'':
-->Urbs Jerusalem beata
-->Dicta pacis visio
-->Quæ construitur in caelis
-->Vivis ex lapidibus
-->Et angelis coronata
-->Ut sponsata comite
** When Berengar is missing, ''Laudate Dominum'':
-->Laudate Dominum, omnes gentes
-->Laudate eum, omnes populi
-->Et veritas Domini, manet in aeternum
-->Gloria Patri et Filio et Spiritui Sancto
-->Sicut erat in principio, et nunc, et semper
** When Malachia comes back from the library in the middle of the chanting, ''In Manus Tuas Domine'':
-->Redemisti nos, Domine Deus veritatis
-->Commendo spiritum meum
-->Gloria Patri et Filio et Spiritui Sancto
-->In Manus Tuas, Domine
-->Commendo spiritum meum
** On the way to the burning of Salvatore and the alleged witch, Ominous Greek Chanting with ''Kyrie/Christe, eleison''.
* OutOfGenreExperience: In-genre [[LitFic for the book]], but the film pauses the action for a theological debate between the progressive, liberal Franciscans and the Vatican emissaries over the question of whether Jesus owned the clothes that he wore.
* {{Pride}}: William's fellow monks regard this as his FatalFlaw when he persists with his investigation when it would be wiser to keep a low profile.
* PunnyName: The abbot's name is Abbo.
* PyrrhicVictory:
** In the book [[spoiler:the library burns, the book is destroyed and Bernardo gets away with the torture and unjust execution of three people]]. This was lightened up a little for the movie.
** History buffs and bibliophiles familiar with the period will consider [[spoiler:the burning of the library]] to be an outright DownerEnding (Eco himself pointed out in the Apostilles to The Name of the Rose (essentially a director's track book) that having a library in that period and not [[spoiler:having it burn down]] would have been absolutely unrealistic.)
* QuoteToQuoteCombat: In their debates about whether it's appropriate to laugh, William and Jorge both quote the Bible and various classical authors extensively.
* RaceLift: Venantius in the movie.
* RansackedRoom: The herbalist discovers the book and goes to tell William of Baskerville, who tells him to lock himself in his room and let no-one in until he arrives (Baskerville is held up by the theological debate). On returning to his apothecary, he shocked to find the place ransacked. He bolts the door and quickly goes to check the book is still there. It is -- lying on the floor under a table. The herbalist is relieved ...until he sees a hooded figure step out from behind a curtain and walk toward him...
* RecycledInSpace: The story is basically a medieval SherlockHolmes mystery in addition to the literary elements.
* RedHerring: [[spoiler: The connection between the various deaths and the seven trumpets of Revelation turns out to be a coincidence after all]]. When this theory is discussed openly, the killer decides to run with it, which complicates things further.
* ReducedToRatburgers: Salvatore, though he quite enjoys them. He catches them in the graveyard, which means they've been [[{{squick}} feeding on corpses]].
* RiddleForTheAges: Adso never learns the girl's name.
* SadisticChoice: Gui insists William, a former victim, serve as a judge in [[UsefulNotes/TheSpanishInquisition the Inquisition]]: in the book, William [[spoiler: is a former inquisitor, who wants nothing more to do with it]]; the movie shows that William [[spoiler: refused to convict a witch and got marched out and judged by Guis-this is HollywoodHistory, as the real inquisitors rarely prosecuted any suspected witches, while most actively disbelieved in witchcraft]].
** In the movie William says he defended a man who translated a book that conflicted with church doctrine. Gui accused him of heresy for doing so, and he was tortured until he recanted his decision, leading to the man's death by burning.
* SatelliteLoveInterest: Taken to an almost comical extreme with the girl, at least in the film. She has no name, no dialogue except for moans during sex, and virtually no characterisation beyond throwing herself at Adso, which she immediately does upon the very first time they meet, without having interacted with him in any way beyond the act of intercourse.
* SecurityCling: In the movie Adso clasps William's robe as they're creeping through the crypt. William is decent enough not to snark at him.
* SexEqualsLove: Adso is convinced he's fallen in love with the girl after their CoitusEnsues encounter. Justified as he's a virgin in a religious order that discourages any interaction with women, and the experience is so intense for him.
-->'''William of Baskerville:''' Are you not confusing love, with lust?\\
'''Adso of Melk:''' Am I? I don't know. I want only her own good. I want her to be happy. I want to save her from her poverty.\\
'''William:''' Oh, dear.\\
'''Adso:''' Why "oh dear"?\\
'''William:''' You ''are'' in love.\\
'''Adso:''' Is that bad?\\
'''William:''' [[DeadpanSnarker For a monk, it does present certain problems.]]
%%* ScarilyCompetentTracker: William.
* SecretPath: The only unguarded way into the library is various secret passages.
* SeriousBusiness: The abbey is hosting a council made up of various factions of the Dominican and Franciscan Orders to debate the burning issue: ''Did UsefulNotes/{{Jesus}} own his own clothes?'' In the film, this is used for comedy; in the book it is always clear that they are really discussing the church's approach to poverty and wealth, and that the debate is therefore highly political and momentous. Other monks spend a great deal of time arguing over the question of ''Did UsefulNotes/{{Jesus}} ever laugh?''
* SexyPriest: The girl throws herself at Adso muttering a language he only partly understands, but the gist is "You are young, and handsome" (given that she had to sleep with two remarkably old and/or ugly monks for sustenance). Adso also mentions receiving love letters from an older monk.
* ShaggyDogStory: [[spoiler:If you read carefully and think about it, you'll notice that this is a detective story where the detective isn't very successful - he even admits it near the end - and the BigBad is never brought to justice.]]
* SherlockScan: William of Baskerville, such as at the beginning, when he meets people from the monastery and describes to them the horse they're looking for, though he never saw it.
** William also later lampshades and deconstructs this technique as being rather reliant on lucky guesses.
* ShoutOut:
** Probably a tenth of the book is either quotations or references to actual antiquary or medieval texts. Whole guidebooks have been devoted to illuminating every single reference Eco makes.
** Aristotle's thought is central to the plot, just as it was in medieval scholasticism. Not only that, [[spoiler: the plot functions much like an Aristotlean tragedy. The hero, William, is so determined to uncover the truth, and the villain, Jorge, is so devoted to piety -- both normally worthwhile virtues -- that they end up destroying the monastery and all its books, accomplishing nothing. Eco even comments on this in [[InWhichATropeIsDescribed the chapter header]] where the library burns down, saying it's caused by an "excess of virtue".]]
** The movie mentions a book by Umberto of Bologna-a clear allusion to Umberto Eco.
** The gruesome ossarium is based on the real-life [[http://en.wikipedia.org/wiki/Capuchin_Crypt Capuchin Crypt.]]
** Further, the name "Baskerville" is an obvious allusion to the Literature/SherlockHolmes novel ''Literature/TheHoundOfTheBaskervilles''. Adso's name sounds very similar to Watson's, and Adso's description of William of Baskerville in the "Prologue" is taken almost word-for-word from Watson's first description of Holmes in ''A Study in Scarlet''. In the movie, William has a line that could be rearranged as "Elementary, my dear Adso" (like the famous BeamMeUpScotty relating to SherlockHolmes).
** And William's first name and political beliefs are modeled on [[OccamsRazor William of Ockham]].
** Jorge, the blind librarian, is a clear reference to Creator/JorgeLuisBorges, the Argentinian author who went blind, served as the director of Argentina's National Library, wrote a story about a labyrinthine library, and is generally credited as a stylistic influence on Eco and probably hundreds of other genre-bending postmodernist authors.
%%* ShownTheirWork: Not surprising, as Eco is a scholar of the Middle Ages.
* SingleMomStripper: The girl is probably a medieval version.
-->'''William:''' Certainly she is a girl from the village who, perhaps not for the first time, grants her favors to some lustful monk out of hunger, and receives as recompense something for her and her family to eat.
-->'''Adso:''' A harlot!
-->'''William:''' A poor peasant girl, Adso. Probably with smaller brothers to feed.
* SparedByTheAdaptation: The girl, of course. Also the Abbot.
* TheSpeechless: The girl in the movie.
* StealthInsult: William tells Bernard he credits him with the most important decision of his life. That decision being to quit being an inquisitor...
* TakeThat: [[spoiler: Jorge Luis Borges. While it's obvious Eco has a lot of respect for him as a writer, the historical Borges's support of right-wing dictators like Augusto Pinochet later in his life makes its way into the character Jorge of Burgos being a fierce authoritarian and reactionary, in keeping with the "Years of Lead" subtext of the novel.]]
* ThemeSerialKiller: The killings follow symbolism from the Book of Revelation. [[spoiler:Subverted; it turns out this is mostly by accident.]]
* TheReasonYouSuckSpeech: William gives one to [[spoiler: Jorge]] at the end.
-->You are the Devil. Yes. They lied to you. The Devil is not the Prince of Matter; the Devil is the arrogance of the spirit, faith without smile, truth that is never seized by doubt. The Devil is grim because he knows where he is going, and in moving, he always returns whence he came. You are the Devil, and like the Devil, you live in darkness. If you wanted to convince me, you have failed. I hate you, [[spoiler:Jorge]], and if I could, I would lead you downstairs, across the grounds, naked, with feathers stuck in your asshole and your face painted like a juggler and a buffoon, so that the whole monastery would laugh at you and be afraid no longer. I would like to smear honey all over you and roll you in feathers and take you on a leash to fairs, to say to all: He was announcing the truth to you and telling you that the truth has the taste of death, and you believed not in his words but in his grimness. And now I say to you that in the infinite whirl of possible things, God allows you to imagine a world where the presumed interpreter of the truth is nothing more than a clumsy raven who repeats words learned long ago.
* TitleDrop: The postfacium quote, the last line of the book. The movie however doesn't say it outright but implies the ''girl'' was the rose with its last line, as Old Adso muses that he never learned her name.
* TomeOfEldritchLore: The lost dialogue of Aristotle is assumed to be this. [[spoiler:It's actually poisoned]].
* ToThePain: Bernardo Gui does the "showing the instruments" version in the movie to Salvatore, who shows [[{{Fingore}} clear signs of having been tortured]] when confessing the next day.
* TortureIsIneffective: Discussed by William who used to be an inquisitor, but avoided using torture. He explains that people under torture say not only what the inquisitor wants, but also what they imagine might please him. Later, when Bernardo Gui interrogates the cellarer, the threat of torture is enough for him to admit that he committed all the murders (which he didn't do).
* TheTower: The hidden and locked library looms over the monastery, tall, dark, [[LivingLabyrinth labyrinthine]] and foreboding. Eco helpfully draws a diagram of it for readers.
* TheUnintelligible: Salvatore, played by Ron Perlman, talks in an idiosyncratic mix of Latin, Italian, English, French and Spanish. Even so far as the words can be understood, his ramblings don't seem to make much sense.
--> ''Salvatore'': "Penitenziagite! Watch out for the draco who cometh in futurum to gnaw your anima! La morte è supremos. You contemplatum the apocalypsum. Là-bas, nous avons il diabolo, ugly comme Salvatore" ([[http://www.youtube.com/watch?v=FIMsxTsofMs in this scene]]).[[labelnote:Translation]]"Repent! Watch out for the dragon that cometh in future to gnaw your soul! Death is supreme. You consider the Apocalypse. [[{{Foreshadowing}} Out there, we have the devil, as ugly as Salvatore]]".[[/labelnote]]
* VomitingCop: Adso plays the rookie cop version, fleeing outside from the autopsy of the first murder victim.
* VillainTeleportation: [[spoiler:Jorge]]'s ability to get in and around the library unseen. {{Handwave}}d in the film, as William muses that Jorge must have flown to reach the library before them. Jorge then says that he took the short route.
* WhamEpisode:
** The third day. Adso [[spoiler:finally learns something about Fra Dolcino!]] Also he [[spoiler:gains "carnal knowledge" of some random young lady!]] And, by the way, [[spoiler:Berengar dies.]]
** [[InvokedTrope Invoked]] by the subtitle to the chapter where the villain explains his plan:
--> "''In which, if it were to summarize the prodigious revelations of which it speaks, the [sub]title would have to be as long as the chapter itself, contrary to usage.''"
* WimpFight: {{Subverted}}: William and Jorge are both senescent intellectuals. They know absolutely nothing about fighting... [[NoHoldsBarredBeatdown but will do absolutely anything to win.]]
%%* WitchHunt: Literally.
* WithAllDueRespect: Adso is respectful as befits a novice, but can't help snarking at his mentor with this trope, when pointing out that William never asks him a question to which he doesn't already know the answer.
* WellIntentionedExtremist: Jorge wants to [[spoiler:destroy the last edition of the Poetics of Aristotle in the film, because he feels that it will teach men to approach all matters with laughter and kill fear of the devil and thus, in ''his'' mind at least, render men irreligious.]]
* TheXOfY
* YourMom: During their final argument about laughter, Jorge mentions a story about a Minorite who fell on the ice, and when someone mockingly asked him if he wanted to lie on something better, he answered: "Yes, your wife".
