It appears then that the ancient Aryan scheme, though possibly supplying us with the origin of one of the widest spread of our words, is not universally allowed to do so. This origin, however, appears to derive support from the apparent occurrence of the original of another well-known ancient classical word in the same scheme, that is Varuna, obviously the same word as Οὐρανος, and Uranus, signifying the heavens. Less clearly too perhaps we may trace other such words to the same source. Thus the Sun, which according to these primitive conceptions is the husband of the Earth, which it nourishes and makes fruitful, was called Savitr and Surya, from which the passage to the Gothic Sauil is within the limits of known etymological changes, and so comes the Lithuanian Saull, the Cymric Haul, the Greek Heilos, the Latin Sol, and the English Solar. So from their Nakt, the destructive, we get Nux, Nacht, Night. From Glu, the Shining, whence the participle Glucina, and so to Lucina, Luena, Luna, Lune.
Turning from the ancient Aryans, whose astronomy we know only from poems and fables, and so learn but little of their actual advance in the science of observation, we come to the Babylonians, concerning whose astronomical acquirements we have lately been put in possession of valuable evidence by the tablets obtained by Mr. Smith from Kouyunjik, an account the contents of which has been given by Mr. Sayce (Nature, vol. xii. p. 489). As the knowledge thus obtained is more certain, being derived from their actual records, than any that we previously possessed, it will be well to give as full an account of it as we are able.
The originators of Babylonian astronomy were not the Chaldæans, but another race from the mountains of Elam, who are generally called Acadians. Of the astronomy of this race we have no complete records, but can only judge of their progress by the words and names left by them to the science, as afterwards cultivated by the Semitic Babylonians. These last were a subsequent race, who entering the country from the East, conquered the original inhabitants about 2000 B.C., and borrowed their civilization, and with it their language in the arts and sciences. But even this latter race is one of considerable antiquity, and when we see, as we shortly shall, the great advances they had made in observations of the sun and moon, and consider the probable slowness of development in those early ages, we have some idea of the remoteness of the date at which astronomical science was there commenced. Our chief source of information is an extremely ancient work called The Observations of Bell, supposed to have been written before 1700 B.C., which was compiled for a certain King Saigou, of Agave in Babylonia. This work is in seventy books or parts, and is composed of numerous small earthen tablets having impressed upon them the cuneiform character in which they printed, and which we are now able to read. We generally date the art of printing from Caxton, in 1474, because it took the place of manuscript that had been previously in use in the West; but that method of writing, if in some respects an improvement on previous methods of recording ideas as more easily executed, was in others a retrogression as being less durable: while the manuscripts have perished the impressions on stone have remained to this day, and will no doubt last longer than even our printed books. These little tablets represented so many leaves, and in large libraries, such as that from which those known have been derived, they were numbered as our own are now, so that any particular one could be asked for by those who might wish to consult it. The great difficulty of interpreting these records, which are written in two different dialects, and deal often with very technical matters, may well be imagined. These difficulties however have been overcome, and a good approach to the knowledge of their contents has been made. The Chaldæans, as is well known, were much given to astronomy and many of their writings deal with this subject; but they did practical work as well, and did not indulge so much in theory as the Aryans. We shall have future occasion in this book to refer to their observations on various points, as they did not by any means confine themselves to the simplest matters; much, in fact, of that with which modern astronomy deals, the dates and duration of eclipses of the sun and moon, the accurate measurement of time, the existence of cycles in lunar and solar phenomena, was studied and recorded by them. We can make some approach to the probable dates of the invention of some part of their system, by means of the signs of the Zodiac, which were invented by them and which we will discuss more at length hereafter. We need only say at present that what is now the sign of spring, was not reckoned so with them, and that we can calculate how long ago it is that the sign they reckoned the spring sign was so.
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.
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.
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
