combined as to produce in each tableau the effect of one general and prevailing tone; so that in many temples there were chambers which can be justly distinguished as the Blue Hall, the Red Hall, or the Golden Hall. So much for the classical period of decoration. [Illustration: Fig. 107.--Wall of a chamber at Denderah, to show the arrangement of the tableaux.] As we come down to later times, these tableaux are multiplied, and under the Greeks and Romans they become so numerous that the smallest wall contained not less than four (fig. 107), five, six, or even eight registers. The principal figures are, as it were, compressed, so as to occupy less room, and all the intermediate space is crowded with thousands of tiny hieroglyphs. The gods and kings are no longer portraits of the reigning sovereign, but mere conventional types without vigour or life. As for the secondary figures and accessories, the sculptor's only care is to crowd in as many as possible. This was not due to a defect of taste, and to the prevalence of a religious idea which decided but enforced these changes. The object of decoration was not merely the delight of the eye. Applied to a piece of furniture, a coffin, a house, a temple, decoration possessed a certain magic property, of which the power and nature were determined by each being or action represented, by each word inscribed or spoken, at the moment of consecration. Every subject was, therefore, an amulet as well as an ornament. So long as it endured, it ensured to the god the continuance of homage rendered, or sacrifices offered, by the king. To the king, whether living or dead, it confirmed the favours granted to him by the god in recompense for his piety. It also preserved from destruction the very wall upon which it was depicted. At the time of the Eighteenth Dynasty, it was thought that two or three such amulets sufficed to compass the desired effect; but at a later period it was believed that their number could not be too freely multiplied, and the walls were covered with as many as the surface would contain. An average chamber of Edfû or Denderah yields more material for study than the hypostyle hall of Karnak; and the chapel of Antoninus Pius at Philae, had it been finished, would have contained more scenes than the sanctuary of Luxor and the passages by which it is surrounded.
