Don Quixote is one of the world's first novels and by far the best-known book in Spanish literature, was originally intended by Cervantes as a satire on traditional popular ballads, yet he also parodied the romances of chivalry. By happy coincidence he produced one of the most entertaining adventure stories of all time and, in Don Quixote and his faithful squire, Sancho Panza, two of the greatest characters in fiction.
