In the East the development of image worship seems to have been earlier than in the West.[471] During the eighth century its corruptions provoked the iconoclastic zeal of the Isaurian Leo; and a general council condemned as idolatrous all symbols of Christ except the holy Eucharist.[472] Their destruction was rigorously prosecuted in the Eastern Empire; but Gregory II. became the champion of image 279 worship in the West, and Italy, adhering to her ancient pagan instincts, substituted this new idolatry for that which she had abandoned. The development of the graven representation of the passion was more gradual than its treatment in graphic art. This was the work of the sculptors. At first the figure of Our Lord was merely painted on a flat surface of wood or metal. This was afterward incised in outline, and exhibited in low relief, as on an ivory diptych of date A. D. 888 in the Vatican Museum. In this the sun and moon, as genii, hold torches above the cross; and by a singular association of ideas, Romulus and Remus, suckled by the wolf, appear at its foot, probably in allusion to Christ’s spiritual subjugation of the Roman Empire.[473] The treatment of this sacred theme passed gradually through the stages of _basso_, _mezzo_, and _alto relievo_, becoming more and more detached, till, in the fourteenth century, the figure of Our Lord upon the cross stood out, the completed and portable crucifix.[474] From this, through rapid stages, we arrive at the gross and ghastly images which abound throughout Roman Catholic Christendom; in every church and at every shrine; in the homes alike of prince and peasant; at the street corners and by the way side; often in popular apprehension endowed with the power of weeping, motion, speech, and working miracles.[475] By such gradations between the soul of man and 280 the living Saviour came the image of the dead Christ, diverting the thoughts from the faith in a living Lord to an idolatrous veneration of a lifeless symbol. Thus, as Dr. Maitland remarks, in painting sight superseded faith, and in sculpture touch superseded sight. But still another resource of sensuousness was to be discovered; and in the year 1223, “when the world was growing cold,”[476] as the Roman Church, with a deeper meaning than it knew, asserted, Saint Francis of Assis is feigned to have received the stigmata of the five wounds of Christ, and thenceforth to have borne about in his body--a living crucifix--the marks of the Lord Jesus. This miracle was afterwards frequently repeated; but the Church, seeking amid the growing darkness of the times to walk by sight and not by faith, wandered ever further and further from the central source of light and power, and lost all ability to communicate to a cold and dying world any spiritual life and warmth.
