Emperor Jones (1920) is another of O'Neill's forays into expressionist theater. It tells the story of a black man who worked as a railroad porter and eventually ends up in the West Indies where, by a bit of fate, raises himself to the role of emperor.
Arthur Miller's Death of a Salesman (1949) chronicles the life of a salesman who, while harboring delusions of grandeur, is ultimately only a cog in the machine of business. The play examines how his failure to grasp reality impacts both his life and the lives of his family.
