On the occasion of the French expedition to Egypt, a long passage was discovered leading from Karnak to Lucksor. This passage was adorned on each side of the way with a range of 1600 sphinxes with the body of a lion and the head of a ram. Now in Egyptian architecture, the ornaments are never the result of caprice or chance; on the contrary, all is done with intention, and what often appears at first sight strange, appears, after having been carefully examined and studied, to present allegories full of sense and reason, founded on a profound knowledge of natural phenomena, that the ornaments are intended to record. These sphinxes and rams of the passage were probably the emblems of the different signs of the Zodiac along the route of the sun. The date of the avenue is not known; but it would doubtless lead us to a high antiquity for the Egyptian observations. The like may be said of the great pyramid, which according to Piazzi Smyth was built about 2170 B.C. Certainly there are no carvings about it exhibiting any astronomical designs; but the exact way in which it is executed would seem to indicate that the builders had a very clear conception of the importance of the meridian line. It should, however, be stated that Piazzi Smyth does not consider it to have been built by the Egyptians for themselves; but under the command of some older race. There seem, however, to be indications in various festivals and observances, which are met with widely over the earth's surface, as will be indicated more in detail in the chapter on the Pleiades, that some astronomical observations, though of the rudest, were made by races anterior even to those whose history we partially possess; and that not merely because of its naturalness, but because of positive evidence, we must trace back astronomy to a source from whence Egyptians, Indians, and perhaps Babylonians themselves derived it. The Chinese astronomy is totally removed from these and stands on its own basis. With them it was a matter concerning the government, and stringent laws were enforced on the state astronomers. The advance, however, that they made would appear to be small; but if we are to believe their writers, they made observations nearly three thousand years before our era. Under the reign of Hoangti, Yuchi recorded that there was a large star near the poles of the heavens. By a method which we shall enlarge upon further on, it can be astronomically ascertained that about the epoch this observation was said to be made there was a star ([Greek: a] Draconis) so near the pole as to appear immovable, which is so far a confirmation of his statement. In 2169 the first of a series of eclipses was recorded by them; but the value of their astronomy seems to be doubtful when we learn that calculation proves that not one of them previous to the age of Ptolemy can be identified with the dates given.
