This is a reprint of the second revised edition of the text and translation of the De Administrando Imperio written and compiled by Emperor Constantine VII Porphyrogenitus in the tenth century. It contains a wide variety of information on both foreign relations and internal administration and is one of the most important historical documents surviving from the Middle Byzantine period. Its confidential character and generally honest appraisal of the empire’s political situation enhance its value for students of Byzantium and Europe during this period. The edition includes general and critical introductions, an index of proper names, and an extensive glossary, as well as grammatical notes and an index of sources and parallel passages.

The Diagram as Paradigm is the first book that looks at medieval diagrams in a cross-cultural perspective, focusing on three regions—Byzantium, the Islamicate world, and the Latin West—each culturally diverse and each closely linked to the others through complex processes of intellectual, artistic, diplomatic, and mercantile exchange.

The volume unites case studies, often of little-known material, by an international set of specialists, and is prefaced by four introductory essays that provide broad overviews of diagrammatic traditions in these regions in addition to considering the theoretical dimensions of diagramming. Among the historical disciplines whose use of diagrams is explored are philosophy, theology, mysticism, music, medicine, mathematics, astronomy, and cosmology. Despite the sheer variety, ingenuity, and visual inventiveness of diagrams from the premodern world, in conception and practical use they often share many similarities, both in construction and application. Diagrams prove to be an essential part of the fabric of premodern intellectual, scientific, religious, artistic, and artisanal life.
