The purpose of this thesis is to show, through the identification of various Sancho figures in American novels, that Don Quixote exerts a continuing tradition in and influence on the novel. The original Sancho can be defined and characterized according to the following: his education; his individuality, made up of equality, democracy, and existentialism; his supposed cowardice; his commitment to Don Quixote; and his attitude toward women (excluding them from the quest). All of these identifying features will be shown to exist in the major character of six selected novels. in Brackenridge's Modern Chivalry, Teague is shown to be the Sancho figure. He is, however, negative in many of the ways that Sancho is positive. He is therefore an unadmirable Sancho. Also, Brackenridge conceives of Sancho's rise as a farce and this affects the characterization of Teague. Huckleberry Finn, in Twain's Adventures of Huckleberry Finn, is an adolescent Sancho Panza whose education and individuality very nearly parallel the original. Hank Morgan emerges as the Sancho figure in Twain's A Connecticut Yankee in King Arthur's Court, sharing most notably his education and individuality. In Steinbeck's Of Mice and Men, George is Sancho to a mentally defective Don Quixote. He shares with Lennie the dream of an island and commits himself completely to his companion. Yossarian is the Sancho figure in Heller's Catch-22 and proves it is possible to have a Sancho without an accompanying Don Quixote. This is possible because of the merging of the character traits of the two originals. Kesey's One Flew Over the Cuckoo's Nest is an example of a contemporary work in which the Sancho and Don Quixote figures are readily identifiable. Chief Bromden and McMurphy play their roles as madmen in an asylum rather than on the plains of Spain. Their exploits appear to be very much influenced by the original Don Quixote. Three of the novels mentioned above are rather recent and indeed show that the figure of Sancho Panza is present in the modern American novel. This indicates that Don Quixote continues its influence on and tradition in the American novel.
