It was probably on this account that we so often find more than one statue of the dead man in the same tomb. The more numerous the statues, the greater chance there was that one at least of them would survive down to the day when the Ka should at last be again united to its body and soul. And the priests of Heliopolis discovered yet a further reason for the practice. From time immemorial Ra the sun-god had been invoked there under the form of his seven birdlike “souls” or spirits, and double this number of Kas was now ascribed to him, each corresponding with a quality or attribute which he could bestow upon his worshippers.(19) Symbols already existed in the hieroglyphics for these various qualities, so that it was easy to regard each of them as having a separate and concrete existence, and so being practically a Ka. The funerary statue and the ideas connected with it seem to have been characteristic of Memphis and the school of theology which existed there. At all events, no similar statues have been discovered at Abydos in the tombs of the first two (Thinite) dynasties; they make their appearance with the rise of Memphite influence under the Third Dynasty. And with the disappearance of the old Memphite empire, they too tend to disappear. The disturbed condition of Egypt after the fall of the Sixth Dynasty was not favourable to art, and it was probably difficult to find artists any longer who could imitate with even approximate accuracy the features of the dead. But under the Theban dynasties another kind of image becomes prominent. This was the Ushebti or “Respondent,” hundreds of which may be seen in most museums. They are usually small figures of blue or green porcelain, with a mattock painted under each arm, and a basket on the back. The name and titles of the deceased are generally inscribed upon them, and not unfrequently the 6th chapter of the Egyptian funerary ritual or Book of the Dead. The chapter reads as follows: “O these _ushebtis_, whatever be the work it is decreed the Osirified one must do in the other world, let all hindrances to it there be smitten down for him, even as he desires! Behold me when ye call! See that ye work diligently every moment there, sowing the fields, filling the canals with water, carrying sand from the West to the East. Behold me when ye call!”
