This achievement was checked by the controversy over the use of graven images, and the proper interpretation of the Second Commandment, which led to the crisis of Iconoclasm or destruction of religious images, which racked the Empire between 726 and 843. The restoration of orthodox iconodulism resulted in a strict standardization of religious imagery within the Eastern Orthodox Church. Byzantine art became increasingly conservative, as the form of images themselves, many accorded divine origin or thought to have been be painted by Saint Luke or other figures, was held to have a status not far off that of a scriptural text.
