In this abbey Abbot Abbot explains to William the discovery of a monk named Adelmo in a ravine; dead, hit by the rocks as he fell, thrown from one of the windows of the abbey building. He authorizes Guillermo to investigate the case. It authorizes you to do everything necessary to clarify the case, unless you enter the library, the best library of all the abbeys, whose entry was totally forbidden to everyone except the librarian, Malachi.
In the abbey there is an old friend of William, called Ubertino da Casale, they talk about the times they spent together. While Guillermo and Adso are in the chapel of the abbey with Ubertino, a perverse-faced monk appears, named Salvatore, who lives in this abbey because he was saved by Ubertino.
That same day Guillermo also spoke with the herbalist monk, severino. Guillermo asked him if he had dealings with Adelmo, the deceased, he said no, that Adelmo lived with other monks, with those who frequented the scriptorium.
They visited the scriptorium where they met Malachi. At that time there was a conversation between monks in which they spoke of Adelmo, Guillermo saw that Berengario, the assistant of the librarian and Venancio maintained a good relationship with Adelmo. Here they also met Jorge, a very old and blind monk.
Guillermo and Adso are taken to a cell where they eat discussing the event of the horse. Without being warned by the abbot, Adso listens to a conversation between him and Guillermo in which in addition to discussing about theological issues, the abbot tells the tragedy of the death of Adelmo, one of the monks, whose mystery Guillermo was sent to discover. The abbot forbids William to enter the library of the abbey. Finally, Guillermo decides to visit his old friend Ubertino who is in the church.
Guillermo and Adso go to the church where Ubertino is and after admiring the cover of this, a strange-looking monk named Salvatore approaches and speaks to them in an incomprehensible language, Guillermo has slight suspicions about him. Already in the church they hold a talk with Ubertino about politics, theology and the current situation of the Franciscans, which will be resolved in a meeting in the following days between the delegates of the Pope and the Franciscans.
Guillermo and Adso are at the exit of the church with Severino, the herbalist, and hold a constructive conversation about herbs and the gardens of the abbey, then this leads him to the building showing him on the way some
Guillermo and Adso direct the scriptorium where they meet with Malaquías de Hidelchein the librarian, who introduces them to many monks who are there; He tells them about the library and shows them the work of the monk who died. Jorge, an old monk waiting for the Antichrist, arrives and begins a controversial conversation with some of the monks present about the drawings and laughter.
Then they met Nicola, the glassmaker monk. Once they entered into conversation, Nicola told Guillermo that very strange things happened in the abbey, especially in the library. That he saw lights at night, that it was very strange, that he did not know if they were will-o’-the-wisps, or the glow of the dead librarians.
Guillermo and Adso leave the library and while the monks carry out their religious services, they go through the rest of the monastery. In the smithy they have a conversation with Nicola da Morimondo, the glazier of the abbey, who explains his theory about the mystery of the library. Once alone, Guillermo and Adso draw their own conclusions about Adelmo’s death, and then head to the dining room.
Many of the monks of the abbey attributed the events to machinations of the evil one, that is, of the devil. But Guillermo did not believe that this was so, nor that the young Adelmo was killed, but rather it was a suicide
While all were praying, alarmed three servants went to the abbot saying there was a dead man. They approached the hog pigs and in a jar filled with pig’s blood was a lifeless man who turned out to be Venancio, the Greek specialist in the library, whom Guillermo met the day before.
They took him to the herbalist’s lab and examined his body. They thought he had been poisoned. Guillermo asked Severino, the herbalist, if he had potions to poison, to which Severino replied that yes, that in the laboratory he had everything, but that he had not missed anything.
Guillermo interrogates two monks, Benció and Berengario, about the death of Adelmo. Benció told him that there was a discussion between Venancio, Adelmo, Berengario and Jorge about a book written by Aristotle which Jorge said did not exist and then Venancio and Adelmo and went to ask something to Berengario. Berengario tells him that he saw Adelmo before he died, walking like a ghost through the cemetery. Guillermo thinks that Adelmo committed suicide because he was tormented by something bad he had done and he blamed it on Berengario whom he saw in the cemetery before his death, who was so frightened that he thought it could have been a vision.
Another monk, Aymaro, also complains that many strange things happen in the abbey, especially in the library.
Then they went up to the scriptorium where Guillermo had a long dialogue with Jorge about laughter, in which Jorge expresses that Christ did not laugh and that laughter is bad they also talk about Aristotle’s book where he talks about laughter but Jorge comments that this book does not exists. After Guillermo approaches the library’s anteroom and approaches the table of the late Venancio to see if he finds any clue about his death, but Bencio tells him to stop the investigation and to follow him, that he has something very important to tell him. After talking to him, Guillermo and Adso, they hesitate if Bencio really wanted to tell them something or what he wanted was to take them away from Venancio’s table.
Bencio tells Guillermo how one night he saw Adelmo running out of Berengario’s cell and how he was chasing him. Then he went to the cemetery and another monk, Venancio, had also observed these actions. The next morning the body of Adelmo appeared. It follows that Berengario was attracted to Adelmo and had some sexual contact that night. Guillermo and Adso decided that it was necessary to enter as it was in the library if they could.
Later Guillermo and Adso talk to the oldest monk in the whole abbey and manage to get him out of the way as the library can be reached once the doors are closed.
At night they enter the scriptorium through an altar of the church and go to the table of Venancio where they find a scroll with phrases in Greek and when approaching it to the flame they see symbols appear, they realize that someone he is atoning for them, he realizes that they have seen him and escapes. Guillermo and Adso chase him but they can not catch him. When Guillermo arrives again at the table of Venancio realizes that his glasses have been stolen, they also miss a book that was on a table.
They get into the library and see that it is built in the form of a labyrinth, with mirrors that distort the image and rooms where you can breathe a smoke that makes you see visions after a long time find the exit of chance. When they left, they met the abbot who told them that he did not know where Berengario was. They looked for him all over the abbey and could not find him. When they go to his cell they see that it is empty but they find a cloth full of blood.
Also engages in a conversation with Salvatore in which he sees that he had been a heretic before arriving at the abbey.
This day Adso has a long conversation with the friar Ubertino where he tells him long stories about Friar Dulcino, a friar who thought that since Christ was poor, all the rich had to be killed. That night Adso finds a village girl in the kitchen, she is surprised, but when they see each other they make love and enjoy their bodies and when all this ends the girl escapes running, Adso discovers horrified a big bleeding heart, wrapped in cloth wrapped cloths that the girl had left. It was an animal heart.
After matins, the abbot orders to find Berengario. A monk finds in his cell a cloth stained with blood. Guillermo goes to the smithy where Nicola the glassmaker to ask for some new glasses, meanwhile also is still asleep.
Also, upon awakening, goes to the scriptorium where he observes the monks as he reflects on the history of his order and the obsession of the monks with the books in the library. At lunchtime he goes to the kitchen.

-One of the points is the library, where it is represented as: the center of the
Knowledge of everything that has been written and that has been saved as part
Of the heritage of humanity. But this is the image of those who do not want
Make this knowledge known by having an erroneous idea; for that reason they prefer
Hide it and get to the point of committing atrocities to avoid revealing
Which they consider to be detrimental to their own interest.
-The theme of the search for truth and the desire to explore what is
Considered “forbidden”, brings consequences for those who want to know what
Had been written in the pages of Aristotle’s book. The subject of what
