According to Jerome’s version of the Chron., Hermon became bishop in the eighteenth year of Diocletian, a.d. 301; according to the Armenian, in the sixteenth year. The accession of his successor Macharius is put by Jerome in the eighth year of Constantine, a.d. 312. Eusebius’ words seem to imply that Hermon was still bishop at the time he was writing, though it is not certain that he means to say that. Jerome’s date may be incorrect, but is probably not far out of the way. Of Hermon himself we know nothing more.
