John of Epiphania was a late sixth century Byzantine historian.
John records Khosrau's restoration to the Persian throne by Maurice. However, Khosrau would use Maurice's murder in 602 as an excuse to resume war with the Byzantines. Khosrau is seen here, finally defeated by Heraclius in the Battle of Nineveh.
The Battle of Nineveh was the climactic battle of the Byzantine–Sasanian War of 602–628.
