Don Quixote is a comedy, which could only have been written by the hitherto obscure genius later in life after he had suffered injury on the battlefield and was subject to periods of harsh confinement in prison. The comedy is bittersweet about this everyman who lives strictly by a code of ancient ethical ideals that inspire him to fits of lunacy, folly and madness. Lucid, indeed inspired, when the subject is anything but knight errantry, Quixote's commitment to his ideals brings him insult, injury, poverty and ridicule.It's a book that everyone must have in his shelve.
Cervantes's Don Quixote (Bloom's Modern Critical Interpretations)
Widely regarded as the world's first modern novel, and one of the funniest and most tragic books ever written, Don Quixote chronicles the famous picaresque adventures of the noble knight-errant Don Quixote de La Mancha and his faithful squire, Sancho Panza, as they travel through sixteenth-century Spain. Unless you read Spanish, you've never read Don Quixote.
