The chief temple, when explored by the French expedition, was deeply buried in the sand. In the front part of it, covering the ceiling, before one enters the temple itself, there is displayed the square zodiac, so called, to which I shall have to refer briefly. The temple was pointed within a few degrees of north; at the north-east corner of the zodiac is a device, since found to represent the sunlight falling upon a statue of the Goddess of the Shrine. Investigations have shown that the zodiac includes a reference to a great many celestial phenomena of the utmost importance. There is no difficulty in recognising some of the zodiacal signs, but there the resemblance to the modern zodiac ends, for the reason that each of the strange processions of mythological personages represents not only constellations, with some of which we may be familiar, but a great deal more. It is noteworthy that the illustration of the very first astronomical point which we have to consider brings out the fact that it is impossible to disconnect Egyptian mythology from astronomy. In the southern half of the zodiac, the lower part is occupied by stars represented in the guise of different mythological personages, sailing along in boats; and above them we get half of the zodiac with the signs of the Fish, the Ram, the Bull and the Twins represented. In the middle section the sun's course in different parts of the day, and different parts of the year, is given: whilst, outermost of all, we get the twelve solar positions, occupied by the sun each hour from rising to setting, represented by twelve boats. It may be here mentioned that in ancient Egypt, as in the modern Eastern world, both day and night always consisted of twelve hours; unequal, of course, the length of the hours varying according to the time of the year. [Illustration: NORTHERN HALF OF THE SO-CALLED SQUARE ZODIAC OF DENDERAH.] Now, if we take the opposite side, that is the north-west corner, we find that we have to do chiefly with the opposite part of the sky, including the signs of the Lion, the Scales, and Sagittarius, and below them other stars are represented as mythological personages in boats. The courses of the sun and moon are next given, and some of the lunar mythology is revealed to us. We see Osiris represented by the moon, and by an eye at the top of fourteen steps, which symbolise the fourteen days of the waxing moon.
