The purposes of this study were to formulate a definition of the "bob-wheel" stanza in which a number of Middle English and Middle Scots poems were written, to inventory and describe these works, with special attention to the structure of individual stanzas, to identify the genres, the periods, and the dialects in which they were written, and to trace their origin and development between the thirteenth and sixteenth centuries. The dissertation includes a general introduction of the topic, chapters on the influence of Latin and Romance stanzaic structure, a chronological survey of the bob-wheel poems, and a conclusion in which theories concerning the origins, development, and decline of the form are discussed.
