In Chapter III of the Second Part of Don Quixote, Bachelor Sansón Carrasco, Don Quixote, and Sancho Panza discuss the First Part of Cervantes’ work. One of the questions addressed is the difference between poetry and history.
“Even so,” responded the bachelor, “some people who have read the history say they would have been pleased if its authors had forgotten about some of the infinite beatings given to Señor Don Quixote in various encounters.”
“That’s where the truth of the history comes in,” said Sancho.
“They also could have kept quiet about them for the sake of fairness,” said Don Quixote, “because the actions that do not change or alter the truth of the history do not need to be written if they belittle the hero. By my faith, Aeneas was not as pious as Virgil depicts him, or Ulysses as prudent as Homer describes him.”
“That is true,” replied Sansón, “but it is one thing to write as a poet and another to write as a historian: the poet can recount or sing about things not as they were, but as they should have been, and the historian must write about them not as they should have been, but as they were, without adding or subtracting anything from the truth.”
The debate that these three men are having centers on an Aristotelian question, treated heavily by 16th and 17th century humanists. In chapter 9 of his Poetics, Aristotle writes:
But it is evident from what has been said that it is not the province of a poet to relate things which have happened, but such as might have happened, and such things as are possible according to probability, or which would necessarily have happened. For a historian and a poet do not differ from each other because the one writes in verse and the other in prose; for the history of Herodotus might be written in verse, and yet it would be no less a history with meter than without meter. But they differ in this, that the one speaks of things which have happened, and the other of such as might have happened.
The poet’s job is to relate what might have happened while the historian’s job is to give an account of what actually happened. But what does Aristotle mean? During the Renaissance, writers try to systematically describe a verisimilitudinous play (i.e. a play that presents events as they might have happened). The 17th century humanist Nicolas Boileau even applies Aristotle to non-theatrical poetry in his Art Poétique (Art of Poetry). The debate concerning the difference between a poet and a historian is also a debate about the role of the public. What does the public expect from a poet vs. from a historian?
Don Quixote, as part meta-fiction, is not only a satire on courtly romance but also a commentary on Renaissance values such as verisimilitude. What does the public expect from a history of Don Quixote? If the story is about a knight errant, should it follow tropes found in the courtly romances that Don Quixote‘s audience know so well? How should Don Quxote act? Don Quixote and Sancho Panza are at once ignorant and self-aware. They behave irrationally, but they know what readers of courtly romance expect. They try to realize in their own lives what a knight or a squire never did historically but might have done poetically. What is ironic about the above conversation is that Don Quixote seems to know that the heroes in his favorite stories were idealized and mythologized, yet he attempts to imitate them anyway. Sancho Panza definitely knows what the public (i.e. Don Quixote) expects because he frequently lies about events to fool and please his master.
