Procopius

Procopius of Caesarea (c. AD 500 - c. AD 565) was a prominent Byzantine scholar from Palaestina Prima. Accompanying the general Belisarius in the wars of the Emperor Justinian I, he became the principal historian of the 6th century, writing the Wars of Justinian, the Buildings of Justinian and the celebrated Secret History. He is commonly held to be the last major historian of the ancient world.
