History of the Wars, Books I and Ii: the Persian War (Dodo Press): 1-2

Procopius of Caesarea (c. 500-c. 565) was a prominent Eastern Roman scholar of the family Procopius. He is commonly held to be the last major ancient historian. The writings of Procopius are the primary source of information for the rule of the Roman emperor Justinian. He was the author of a history in eight books of the wars fought by Justinian I, a panegyric on Justinian's public works throughout the empire, and a book known as The Secret History of the Court of Justinian that claims to report the scandals that Procopius could not include in his published history. Although it is not as famous as The Secret History of the Court of Justinian, Procopius' History of the Wars is clearly his most important work. The first seven books, which were published as a unit, seem to have been largely completed by 545, but were updated to mid-century before publication, for the latest event mentioned belongs to early 551. Later, Procopius added an eighth book which brings the history to 552/553, when a Roman army led by the eunuch Narses finally destroyed the Ostrogothic kingdom.
