Thus the tombs of the Theban period embody the Egyptian solution of the problem which has always exercised mankind. Their subterranean corridors were a reproduction upon a small scale of the leading characteristics of the under world, and we should commit a great mistake were we to look upon the series of pictures which decorate its walls as mere ornament resulting from a desire for luxury and display. Between the ideal models of these pictures and the pictures themselves the Egyptians established one of those mutual confusions which have always been readily accepted by the faithful. Nothing seemed more natural to the Egyptian, or to the Ethiopian who was his pupil, than to ascribe the power of speech and movement to the images of the gods, even when they had painted or carved them with their own hands. This M. Maspero has shown by an ingenious collation of various texts.[258] The chisel which created such tangible deities gave them something more than the appearance of life. Each god exercised his own proper function in that tomb which was a reproduction in small of the regions of the other world. His gestures and the written formulæ which appeared beside him on the walls, each had their protective or liberating power. To represent the king in his act of self-justification before Osiris was in some measure to anticipate that justification. The reality and the image were so intimately commingled in the mind of the believer that he was unable to separate one from the other. [258] _Recueil de Travaux_, vol. i. pp. 155-159.
