Procopius
The writings of Procopius are the primary source of information for the rule of the Roman emperor Justinian. Procopius was the author of a history in eight books of the wars fought by Justinian I, with information on Justinian's public works throughout the empire, and a book known as the Secret History (Greek: Anekdota) that claims to report the scandals that Procopius could not include in his published history.
