The book explores five major themes, all subjects of controversy. "Absence" asks why Byzantium is routinely passed over, ignored, or relegated to a sphere of its own. "Empire" reinserts Byzantium into modern debates about empire, and discusses the nature of its system and its remarkable longevity. "Hellenism" confronts the question of the "Greekness" of Byzantium, and of the place of Byzantium in modern Greek consciousness. "The Realms of Gold" asks what lessons can be drawn from Byzantine visual art, and "The Very Model of Orthodoxy" challenges existing views of Byzantine Christianity. Throughout, the book addresses misconceptions about Byzantium, suggests why it is so important to integrate the civilization into wider histories, and lays out why Byzantium should be central to ongoing debates about the relationships between West and East, Christianity and Islam, Catholicism and Eastern Orthodoxy, and the ancient and medieval periods. The result is a forthright and compelling call to reconsider the place of Byzantium in Western history and imagination.
