 John of Ephesus records a persecution of Baalbek's pagans as late as 580 and no record apart from copies of Pelagia's hagiography lists a Nonnus as a bishop of Heliopolis, although his story is sometimes conflated with the Nonnus known to have been a bishop of Edessa in Mesopotamia and who attended the 451 Council of Chalcedon.This Nonnus has been further conflated with the contemporary poet Nonnus of Panopolis, but this is probably a mistake.Another Nonnus present at Chalcedon was the bishop of Zerabenna in Arabia, which lay under the jurisdiction of Antioch.
