This thesis presents four categories of form basic to all of Stephen Crane's poetry: antiphons, apologues, emblems, and testaments. A survey of previous shortcomings in the critical acceptance of Crane as a poet leads into reasons why the categorization of form here helps to alleviate some of those problems. The body of the thesis consists of four chapters, one for each basic form. Each form is defined and explained, exemplary poems in each category are explicated, and specifics are given as to what makes one poem better than the next. The thesis ends with an elevation of Crane's worth as a poet and a confirmation of the merits of this new categorization of form.
