"Don Quichot van La Mancha" by Miguel de Cervantes Saavedra is a Spanish novel published in two parts in 1605 and 1615. A minor nobleman reads so many chivalric romances that he loses his grip on reality and decides to become a knight-errant himself. Renaming himself Don Quixote, he recruits a simple farmer as his squire and sets out to revive chivalry. Together they embark on adventures where Don Quixote's delusions transform windmills into giants and inns into castles, blurring the line between fantasy and reality.
