In the nineteenth century, American tourists, scholars, evangelists, writers, and artists flocked to Palestine as part of a 'Holy Land mania.' Many saw America as a New Israel, a modern nation chosen to do God's work on Earth, and produced a rich variety of inspirational art and literature about their travels in the original promised land, which was then part of Ottoman-controlled Palestine. In American Palestine, Hilton Obenzinger explores two 'infidel texts' in this tradition: Herman Melville's Clarel: A Poem and Pilgrimage to the Holy Land (1876) and Mark Twain's The Innocents Abroad: or, The New Pilgrims' Progress (1869). As he shows, these works undermined in very different ways conventional assumptions about America's divine mission.
