Themes covered by the contributions include: questions of dynasty and imperial families; the imperial court and the emperor’s men; imperial duties and the emperor as ruler; imperial literature (the emperor as subject and author); and the material emperor, including imperial images and spaces. The volume fills a need in the field and the market, and also brings new and cutting-edge approaches to the study of the Byzantine emperor. Although the volume cannot hope to be a comprehensive treatment of the emperor in the Byzantine world it aims to cover a broad chronological and thematic span and to play a vital part in setting the agenda for future work. The subject of the Byzantine emperor has also an obvious relevance for historians working on rulership in other cultures and periods.
