burned monasteries and images and turned churches into stables, according to the surviving iconophile sources. In 754 Constantine summoned the Council of Hieria in which some 330 to 340 bishops participated and which was the first church council to concern itself primarily with religious imagery. Constantine seems to have been closely involved with the council, and it endorsed an iconoclast position, with 338 assembled bishops declaring, "the unlawful art of painting living creatures blasphemed the fundamental doctrine of our salvation--namely, the Incarnation of Christ, and contradicted the six holy synods. ... If anyone shall endeavor to represent the forms of the Saints in lifeless pictures with material colors which are of no value (for this notion is vain and introduced by the devil), and does not rather represent their virtues as living images in himself, etc. ... let him be anathema." This Council claimed to be the legitimate "Seventh Ecumenical Council", but its legitimacy is disregarded by both Orthodox and Catholic traditions as no patriarchs or representatives of the five patriarchs were present: Constantinople was vacant while Antioch, Jerusalem, and Alexandria were controlled by Muslims, and Rome did not send a representative. The iconoclast Council of Hieria was not the end of the matter, however. In this period complex theological arguments appeared, both for and against the use of icons. Constantine himself wrote opposing the veneration of images, while John of Damascus, a Syrian monk living outside of Byzantine territory, became a major opponent of iconoclasm through his theological writings. It has been suggested that monasteries became secret bastions of icon support, but this view is controversial. A possible reason for this interpretation is the desire in some historiography on Byzantine Iconoclasm to see it as a preface to the later Protestant Reformation in western Europe, in which monastic establishments suffered damage and persecution. In opposition to this view, others have suggested that while some monks continued to support image veneration, many others followed church and imperial policy. The surviving sources accuse Constantine V of moving against monasteries, having relics thrown into the sea, and stopping the invocation of saints. Monks were forced to parade in the Hippodrome, each hand-in-hand with a woman, in violation of their vows. In 765 St Stephen the Younger was killed, and was later considered a martyr to the Iconophile cause. A number of large monasteries in Constantinople were secularised, and many monks fled to
