First published in 1726 as Travels into Several Remote Nations of the World, Jonathan Swift's most famous book presents itself as the plain memoir of Lemuel Gulliver, a ship's surgeon with a gift for being shipwrecked somewhere impossible.
Four voyages carry him to Lilliput, where a court of six-inch people wages war over which end of an egg to crack; to Brobdingnag, where he becomes a giant queen's curiosity and finds English politics looking very small indeed; to the floating island of Laputa and the ruined academies below it; and at last to the country of the Houyhnhnms, rational horses whose decency leaves him unable to bear the company of his own species.
Swift wrote it as a parody of the popular travel narrative, and the joke holds: the deadpan reporting of marvels is exactly what makes the satire land. Beneath the adventure is a steady interrogation of pride, faction, empire and the reasoning animal's high opinion of itself.
