According to tradition Cervantes first conceived his comic masterpiece in jail - his avowed intent being to debunk the romances of chivalry. From first publication Don Quixote was a best-seller, initially taken as a knockabout account of a mad Spanish gentleman and his cowardly peasant squire, but later reinterpreted as an enlightenment text, a representation of universal human nature, a myth of a tragic hero defending man's nobler aspirations, a study in alienation, a spiritual autobiography, a metaphor for Spain's imperial decline, an experimental novel that shaped later prose fiction, a tragedy and comedy in one, and a demonstration that ambiguity and uncertainty can lie at the centre of great art and that great art can be comic.
