While an exile from Constantinople, the twelfth-century Byzantine functionary and canonist John Zonaras culled earlier chronicles and histories to compose an account of events from creation to the reign of Alexius Comnenus. For topics where his sources are lost or appear elsewhere in more truncated form, his testimony and the identification of the texts on which he depends are of critical importance. For his account of the first two centuries of the Principate, Zonaras employed now-lost portions of Cassius Dio. From the point where Dio’s History ended, to the reign of Theodosius the Great (d. 395), he turned to other sources to produce a uniquely full historical narrative of the critical years 235-395, making Books XII.15-XIII.19 of the Epitome central to the study of both late Roman history and late Roman and Byzantine historiography. This key section of the Epitome , together with Zonaras’ Prologue , here appears in English for the first time, both complemented by a historical and historiographical commentary. A special feature of the latter is a first-ever English translation of a broad range of sources which illuminate Zonaras’ account and the historiographical traditions it reflects. Among the authors whose newly translated works occupy a prominent place in the commentary are George Cedrenus, George the Monk, John of Antioch, Peter the Patrician, Symeon Magister, and Theodore Scutariotes. Specialized indices facilitate the use of the translations and commentary alike. The result is an invaluable guide and stimulus to further research for scholars and students of the history and historiography of Rome and Byzantium.
Joannes or John Zonaras (Greek: Ἰωάννης Ζωναρᾶς Iōánnēs Zōnarâs; 1074 - 1159) was a Byzantine Greek historian, chronicler and theologian who lived in .
Under Emperor Alexios I Komnenos he held the offices of head justice and private secretary (protasēkrētis) to the emperor, but after Alexios' death, he retired to the monastery on the Island of Hagia Glykeria,(Incir Ada, in the Aegean Sea), where he spent the rest of his life writing books.
His most important work, Extracts of History (Greek: Ἐπιτομὴ Ἱστοριῶν, Latin: Epitome Historiarum), in eighteen books, extends from the creation of the world to the death of Alexius (1118).
The earlier part is largely drawn from Josephus; for Roman history he chiefly followed Cassius Dio up to the early third century.
Contemporary scholars are particularly interested in his account of the third and fourth centuries, which depend upon sources, now lost, whose nature is fiercely debated. Central to this debate is the work of Bruno Bleckmann, whose arguments tend to be supported by continental scholars but rejected in part by English-speaking scholars.[
An English translation of these important sections has recently been published.[The chief original part of Zonaras' history is the section on the reign of Alexios I Komnenos, whom he criticizes for the favour shown to members of his family, to whom Alexios entrusted vast estates and significant state offices.
