The second revelation was that the walls of these temples, and of many funereal buildings, were, for the most part, covered with inscriptions in the language which was then but gradually emerging from the unknown, its very alphabet and syllabary being still incomplete. Hence there was not only a great wealth of temple buildings, but a still more wonderful wealth of temple inscriptions. [Illustration: THE CENTRAL PORTION OF THE CIRCULAR ZODIAC OF DENDERAH.] There was even more than this, and something more germane to our present purpose. In several temples which were examined, zodiacs--undoubted zodiacs, representing a third group of finds--were discovered; these, also, were accompanied by inscriptions of an obviously astronomical nature. At the first blush, then, it seemed to be perfectly certain that we had to deal with a people of an astronomical turn of mind; and here was the opportunity for the astronomer, which indeed the French astronomers did not fail to make use of. Where the philologist was for the moment dumb, it seemed as if the astronomer could be of use, giving explanations, fixing probable dates on the one hand; while, on the other, he would certainly be gaining a fresh insight into, and possibly filling a tremendous gap in, the history of his science. The figure on the preceding page gives an idea of the method of presentation generally employed in these zodiacs. I shall show in the sequel--for I shall have to deal with this part of my subject at full length in a subsequent chapter--that many of the animal forms represent at once mythological personages and actual constellations. CHAPTER III. THE ASTRONOMICAL BASIS OF THE EGYPTIAN PANTHEON. It will be abundantly clear from the statements made in the foregoing chapter that, as I have said, the main source of information touching things Egyptian consists no longer in writings like the Vedas, but in the inscriptions on the monuments, and the monuments themselves. It is true that, in addition to the monuments, we have the Book of the Dead, and certain records found in tombs; but, in the main, the source of information which has been most largely drawn upon consists in the monuments themselves--the zodiacs being included in that term. It has been impossible, up to the present time, to fix with great accuracy the exact date of the earliest monuments. This should not surprise us. We must all feel that it is not a question of knowing so little--it is a question of knowing anything at all. When one considers that at the beginning of this century not a sign on any of these monuments was understood, and that now the wonderful genius of a small number of students has enabled Egyptologists to read the inscriptions with almost as much ease and certainty as we read our morning papers: _this_ is what is surprising, and not the fact that we as yet know so little, and in many cases lack certainty.
