It would seem that it was not very long before the Egyptians saw that the paths of the sun and stars above the horizon were extremely unequal: in the case of the sun, at different times of the year; in the case of the stars, depending upon their position near the equator or either pole. In this way, perhaps, we may explain a curious variant of the drawing of the goddess Nu-t, in which she is represented double, a larger one stretching over a smaller one. Not only the Sun-gods, but the stars, were supposed to travel in boats across the firmament from one horizon to the other. The underworld was the abode of the dead; and daily the sun, and the stars which set, died on passing to the regions of the west, or Amenti, below the western horizon, to be born again on the eastern horizon on the morrow. In this we have the germ of the Egyptian idea of immortality. [Illustration: THE GODDESS NU-T.] Among other gods which may be mentioned are Chnemu, the "Moulder," who was thought to possess some of the attributes of Rā; and Ptah, the "Opener," who is at times represented with Isis and Nephthys, and then appears as a form of Osiris. We can now begin to glimpse the Egyptian mythology. Seb, the Earth, was the husband of Nu-t, the Sky; and the Sun-and Dawn-gods and-goddesses were their children, as also were Shu representing sunlight, and Tefnut representing the flames of dawn. Maāt, the goddess of law, was the daughter of Rā. [Illustration: THE GODDESS NU-T REPRESENTED DOUBLE.] [Illustration: VARIOUS FORMS OF SHU.] We know several points regarding Egyptian customs independently of the astronomical inscriptions, properly so-called, to which I have called attention. We know that there were sacrifices at daybreak; we know that stars were watched before sunrise, and heralded the dawn; we know that these observations were among the chief duties of the sacrificial priests, and it is obvious that a knowledge of star-places, as well as star-names, must have been imperative to these morning watchers, who eventually compiled lists of decans--that is, lists of belts of stars extending round the heavens, the risings of which followed each other by ten days or so. These are the exact equivalents of the moon-stations which the Indians, Arabians, and other peoples invented for the same purpose. We also find, more or less indeterminately from inscriptions in some graves at Thebes, that the daily risings of the chief stars were observed very carefully throughout the year. Unfortunately the inscriptions in question are very difficult indeed to co-ordinate. There have been various efforts made to connect them with certain stars, but, so far, I am afraid they have resisted all efforts to get a complete story out of them, though certain very important points have been made out. These points I shall consider later. [Illustration: FORMS OF PTAH, THE GOD OF MEMPHIS.]
