Don Quixote

The real subject isn't chivalry, it's reading — Alonso Quixano doesn't so much lose his mind as lose it to books, and Cervantes stages the whole adventure as a referendum on what fiction does to people who take it too seriously. The windmills aren't a joke about delusion so much as a joke about narrative will: a man decides which story he's living in, then bends the world until it supplies the plot. Sancho Panza, the illiterate skeptic who signs on for a donkey and a salary and stays for something closer to love, is the book's real education — by Part II he's fluent in his master's idiom of insulas and honor even as Quixote, coaching him toward the governorship, has absorbed some of Sancho's earthy sense.

Part II, published a full decade after Part I and partly in fury at a hack named Alonso Fernández de Avellaneda who'd rushed out a fraudulent sequel, is what makes the book modern rather than merely funny. Quixote and Sancho now meet people who have read Part I; they're famous inside their own story, and a Duke and Duchess stage elaborate, cruel pranks precisely because they already know the script the 'real' Quixote is supposed to perform. Cervantes even has his characters denounce Avellaneda's counterfeit by name. That's a novel eating its own tail two and a half centuries before anyone had a word for it.

The Duke hands Sancho a fake 'insula' to govern as a cruel joke, expecting a buffoon — and Sancho, to everyone's astonishment, rules with plain, humane justice, untangling property disputes with folk logic sharper than any judge's. What finally breaks him isn't the workload but one prank too many: his tormentors stage a fake 'invasion' of the island and arm him for a battle that turns out to be theater, and Sancho, trampled and terrified, decides no governorship is worth this. He resigns after ten days, exhausted and broke but uncorrupted, telling his tormentors he'd rather go back to the fields 'naked' than govern dishonestly. It's the clearest proof in the book that the line between fool and sage was always Cervantes's real joke, not the one about giants and windmills.
