Don Quixote has become so entranced by reading chivalric romances that he determines to become a knight-errant himself. In the company of his faithful squire, Sancho Panza, his exploits blossom in all sorts of wonderful ways. While Quixote's fancy often leads him astray—he tilts at windmills, imagining them to be giants—Sancho acquires cunning and a certain sagacity. Sane madman and wise fool, they roam the world together, and together they have haunted readers' imaginations for nearly four hundred years.

With its experimental form and literary playfulness, Don Quixote has been generally recognized as the first modern novel. The book has been enormously influential on a host of writers, from Fielding and Sterne to Flaubert, Dickens, Melville, and Faulkner, who reread it once a year, "just as some people read the Bible."

Miguel de Cervantes y Cortinas, later Saavedra was a Spanish novelist, poet, and playwright. His novel Don Quixote is often considered his magnum opus, as well as the first modern novel.

It is assumed that Miguel de Cervantes was born in Alcalá de Henares. His father was Rodrigo de Cervantes, a surgeon of cordoban descent. Little is known of his mother Leonor de Cortinas, except that she was a native of Arganda del Rey.

In 1569, Cervantes moved to Italy, where he served as a valet to Giulio Acquaviva, a wealthy priest who was elevated to cardinal the next year. By then, Cervantes had enlisted as a soldier in a Spanish Navy infantry regiment and continued his military life until 1575, when he was captured by Algerian corsairs. He was then released on ransom from his captors by his parents and the Trinitarians, a Catholic religious order.
