THE 149th Chapter ot the Ritual suffices of itself to demonstrate the astronomical nature of the Egyptian mythology after it had passed out of the first elementary phase. This chapter, said to be the most profoundly mystical and absolutely incomperable is the “Book of instructing the Spirit, the Delight of the Sun, who prevails as Atum, and is rendered great as Osiris.” “There is not known any other such, at any time, or anywhere. No men hath spoken it; no eye hath perceived it; no ear hath heard it; not any other face hath looked in it to learn it. Do not thou multiply its chapters,1 or do not thou let any face except thy own see it and eat thy heart, doing it in the midst of the Hall of Clothes (the Judgement Hall). It is put forth by the God with all his power. It is a true Secret; when it is known all the providers in all places supply the dead (Spirit) in Hades; food is given to his soul on earth; he is made to live for ever; nothing prevails against him.”2 The contents of this chapter show that the secret of its revelation, considered to be of such supreme importance in the eschatological phase, belonged to the Gnosis of the celestial allegory, the earliest formation of the starry heavens, and a knowledge of the Seven Cows and the Bull; the Four mystical Eyes; the Four paddles of the boat of the Sun, which are arranged according to the four corners or points of the compass.
