Don Quixote

Don Quixote is a Spanish novel by Miguel de Cervantes. It was originally published in two parts, in 1605 and 1615. Considered a founding work of Western literature, it is often labelled as the first modern novel. Don Quixote is also one of the most-translated books in the world and one of the best-selling novels of all time.
The plot revolves around the adventures of a member of the lowest nobility, an hidalgo[d] from La Mancha named Alonso Quijano, who reads so many chivalric romances that he loses his mind and decides to become a knight-errant (caballero andante) to revive chivalry and serve his nation, under the name Don Quixote de la Mancha. He recruits as his squire a simple farm labourer, Sancho Panza, who brings a unique, earthy wit to Don Quixote's lofty rhetoric. In the first part of the book, Don Quixote does not see the world for what it is and prefers to imagine that he is living out a knightly story meant for the annals of all time. However, as Salvador de Madariaga pointed out in his Guía del lector del Quijote (1972 [1926]), referring to "the Sanchification of Don Quixote and the Quixotization of Sancho", as "Sancho's spirit ascends from reality to illusion, Don Quixote's declines from illusion to reality".
