Procopius of Caesarea was born in the latter years of the fifth century at Caesarea in Palestine. He originated from the land-owning provincial upper class and, like Zosimus, became a civil servant. As early as A.D. 527, before the emperor Justin's death, Procopius became counsellor, assessor, and secretary to Belisarius, whose fortunes and campaigns he followed for the next twelve or fifteen years. Small wonder he became very knowledgeable of military affairs through this service. He has long been respected as a historian of the emperor Justinian’s wars, and in fact he is reckoned the greatest of the later Greek historians. Procopius was finally raised to the dignity of an illustrius, and died not earlier than A.D. 562.
