Semiramis also raised in the centre of Babylon a temple consecrated to Jupiter, whom the Babylonians called Bel. It was of an extraordinary height and served for an observatory. The whole edifice was constructed with great art in asphalte and brick. On its summit were placed the statues of Jupiter, Juno, and Rhea, covered with gold.
The Egyptians have always been named as the earliest cultivators of astronomy by the Grecian writers, by whom the science has been handed down to us, and the Chaldæans have even been said to have borrowed from them. The testimony of such writers however is not to be received implicitly, but to be weighed with the knowledge we may now obtain, as we have noticed above with respect to the Babylonians, from the actual records they have left us, whether by actual records, or by words and customs remaining to the present day.
Plate I.—Babylonian Astronomers.
Herodotus declares that the Egyptians had made observations for 11,340 years and had seen the course of the sun change four times, and the ecliptic placed perpendicular to the equator. This is the style of statement on which opinions of the antiquity of Egyptian astronomy have been founded, and it is obviously unworthy of credit.
Diodorus says that there is no country in which the positions and motions of the stars have been so accurately observed as in Egypt (i.e. to his knowledge). They have preserved, he says, for a great number of years registers in which their observations are recorded. Expositions are found in these registers of the motions of the planets, their revolutions and their stations, and, moreover, the relation which each bears to the birthdays of animals, and its good or evil influence. They often predicted the future with success. The earthquakes, inundations, the appearance of comets, and many other phenomena which it is impossible for the vulgar to know beforehand, were foreseen by them by means of the observations they had made over a long series of years.
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.
