In the case of the Italian Renaissance the decadence was not due to the same cause. The art of Greece declined gradually in respect of quantity as well as quality, while in Italy after the decay in quality set in, art was as nourishing as ever from the point of view of demand. The change in the character of the art was due entirely to Raphael's achievements. As with the early Greek, nearly the whole of the early Italian art was concerned with religion, though in this case there were very few ideals. The numerous ancient gods of Greece and Rome were long gone, to become only classical heroes with the Italians, and their places were taken by twenty or thirty personages from the New Testament. Incidents from the Old Testament were sometimes painted, but nearly all the greater work dealt with the life of Christ and the Saints. The painters of the first century of the Renaissance distributed their attention fairly equally among these personages, but as time went on and the art became of a superior order, artists aimed at the highest development of beauty that their imaginations could conceive, and hence the severe beauty that might be shown in a picture of Christ or a prominent Saint, had commonly to give way to a more earthly perfection of feature and form, which, suggesting an ideal, could only be given to the figure of the Virgin. And so the test of the power of an artist came to be instinctively decided by his representation of the Madonna. No doubt there were many persons living in the fifteenth century who watched the gradually increasing beauty of the Madonna as depicted by the succession of great painters then working, and wondered when and where the summit would be reached--when an artist would appear beyond whose work the imagination could not pass, for there is a limit to human powers.
