(1605–1615) A novel by Miguel de Cervantes. The hero, Don Quixote (don is a Spanish title of honor), loses his wits from reading too many romances and comes to believe that he is a knight destined to revive the golden age of chivalry. A tall, gaunt man in armor, he has many comical adventures with his fat squire, Sancho Panza.
