This is a collection of Greek and Latin inscriptions and papyri in English translation. They are all primary sources for our knowledge of the history of Rome from the first emperor, Augustus, to Hadrian. The theme of the present collection is the political and military activity of the Roman emperors to the period of Hadrian, the men who carried out their policies, the institutions of their administrations, the wars they conducted, the reaction of their subjects, the imperial ruler cult, their letters and orders. A second part is concerned with the society of the ordinary citizen or provincial subject in his daily life. Brief commentary and notes accompany the translations, making this book a collection of historical material to supplement the major literary sources like Tacitus, Suetonius, Dio and others in the study of Roman imperial history. This book will be useful to students and teachers of Roman history and classical civilisation.
