John of Antioch (historian)

John of Antioch (Greek: Ίωάννης Άντιοχείας) was a 7th-century chronicler, who wrote in Greek. He was a monk, apparently contemporary with Emperor Heraclius (reigned 610–41). Heinrich Gelzer identifies the author with the Syrian Orthodox Patriarch of Antioch John of the Sedre, who ruled from 630 to 648.
