The De Thematibus ('on the themes') of Constantine VII Porphyrogenitus

This volume presents an English translation of The De Thematibus, shedding light on the military provinces of the Byzantine Empire and their historical significance.

The treatise titled The De Thematibus ('on the themes') of Constantine VII Porphyrogenitus delves into the military provinces, known as 'themes', of the Byzantine Empire during the 10th century. This work is particularly intriguing due to its blend of historical geography, imperial propaganda, and various legends drawn from ancient sources. Although attributed to Emperor Constantine VII, the authorship remains a topic of debate among scholars, raising questions about the accuracy and intent behind the text.

The purpose behind the creation of The De Thematibus is not entirely clear, as it does not provide a comprehensive historical account of the themes' evolution nor does it utilize available administrative resources that could have informed its content. This ambiguity adds to the enigmatic nature of the work, making it a fascinating subject for both historians and enthusiasts of Byzantine studies.

Despite its significance, The De Thematibus has remained untranslated into English, limiting access for students and non-specialists alike. This volume aims to bridge that gap by offering a translation accompanied by detailed notes and three introductory chapters. These chapters provide essential context regarding the historical background of the text, Byzantine geographical concepts, and the discussions surrounding the themes, making this work more accessible to a broader audience.
