The spaces to be covered were vast, but the warlike kings of Assyria cut out enough work for their sculptors to keep them always busy. Every campaign, and every battle, every siege or passage of a river, seemed to them worthy of commemoration by the chisel. Those to whom the work was given were forced therefore to multiply figures; the task was complicated and yet had to be finished with extreme rapidity. The sovereign was in a hurry to enjoy the spectacle he had promised himself, he wished to inhabit for as many years as possible the dwelling whose walls, like so many magic mirrors, would reflect his own prowess and glory. And so the sculptor had to produce much and produce fast; we can therefore understand how it was that his creations never lost a certain look of improvisation. They had the good qualities of such a mode of work; namely, force, vitality, and _abandon_, but combined with all its defects, inequality, incoherence, and frequent repetition. In order to cover the surface abandoned to the sculptor as quickly as possible, the work had to be divided; every one who was thought to be capable of wielding a chisel had to be pressed into the service. Sculptors of established fame who had already helped to decorate more than one palace, mediocre artists with more age and experience than talent, young apprentices entering the workshops for the first time, all were enlisted, and each received his share of the common task. Under such conditions, and especially when the utmost expedition was required, the collective work could not help showing signs of the many and variously skilled hands that had been employed upon it. Even with the Greeks, and even, which is still more to the point, with the Athenians of the age of Pericles, something of the same kind is to be noticed. The frieze of that temple of Pallas, which is, perhaps, the most carefully wrought creation of human hands, is not all equally fine in execution. Some parts show the work merely of a skilful carver, while before others we feel that here has been the hand of the great master himself, that the play of the chisel has been governed by the brain that traced the original sketch and thought out the whole marvellous conception.
