The iconoclast, was emperor 740-775.
His son Gegnesius in 722 was taken to Constantinople, where he won over to his opinions the iconoclast emperor, Leo the Isaurian.
The iconoclast emperor Leo V., an Armenian, persecuted the sect afresh, and provoked a rising at Cynoschora, whence many fled into Saracen territory to Argaeum near Melitene.
The worship of images never seems to have taken root among Armenians; indeed they supplied the Greek world with iconoclast soldiers and emperors.
But the tide of conquest was stemmed by the iconoclast emperors, and the Arab expeditions, excepting those of Harun al-Rashid, 781 and 806, and of elMotasim, 838, became simply predatory raids.
