"L'ingénieux chevalier Don Quichotte de la Manche" by Miguel de Cervantes Saavedra is a Spanish novel published in two parts in 1605 and 1615. A nobleman named Alonso Quijano reads so many chivalric romances that he loses his mind and decides to become a knight-errant under the name Don Quixote. He recruits a simple farm laborer, Sancho Panza, as his squire. Together they embark on adventures where Don Quixote mistakes windmills for giants and imagines a world of chivalry that doesn't exist, while Sancho provides earthy wisdom to his master's fantasies.
