''Baudolino'' is a 2000 novel by Creator/UmbertoEco.

During the sacking of Constantinople in 1204, Baudolino of Alessandria finds historian Niketas Choniates and saves his life. They decide to hide, along with other people, for as long as the sacking of the city continues. To pass the time, Baudolino decides to tell Niketas of his journeys and adventures in the mythical world of 12th century Europe, as a member of the court of Frederick Barbarossa and more. But as a caveat, he warns Niketas that he [Baudolino] has lived his whole life lying through his teeth every chance he had. After that, he starts…
!! ''Baudolino'' provides examples of the following tropes:

* AccidentalTruth: Many of the more outlandish elements of Baudolino's letter turned out to be true. If Baudolino was telling the truth in the first place.
* AllJewsAreCheapskates: Well, at least the one that appears prominently.
* BeenThereShapedHistory: Baudolino is apparently responsible for quite a few of Barbarossa's decisions.
* BelievingTheirOwnLies: This is one of the main themes of the book. Baudolino and his friends go on a quest to find the kingdom of Prester John, even though they have no evidence that it exists; most people think it does because of a fake letter made by Baudolino's group. [[spoiler:And if Baudolino made up the whole quest, he still falls victim to this trope at the end, when he rides away alone in search of the mythical land again.]]
%%* BewareTheNiceOnes:
%%** The Archpoet.
%%** Baudolino.

* DeathSeeker: In the kingdom of Deacon John, there are a group of warriors who all want to die in battle, because they believe that then they'll go to heaven. The main characters think that this will make them good fighters in an impending war, since they won't be afraid. They are wrong, because they don't even fight, just ask the enemy to kill them.
* DirectLineToTheAuthor: ''Baudolino'' alleges to be [[spoiler:a DeletedScene of sorts from the real Niketas's chronicles, which he removed on the advice of the sage Paphnutius. However, Paphnutius tells Niketas that one day, an even greater liar than Baudolino will tell the ostensibly true story of Baudolino reciting his fictional tale to Niketas, i.e. Umberto Eco himself.]]
