Procopius of Caesarea (Greek: Προκόπιος ὁ Καισαρεύς, Latin: Procopius Caesarensis; c. AD 500 – c. AD 560) was a prominent late antique scholar from Palaestina Prima. Accompanying the Roman general Belisarius in the wars of the Emperor Justinian, 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 Western world.
