It will be noticed that the Classical age did not commence until about the time of the completion of the last books of the Old Testament; so we do not find any reference in Holy Scripture to the astronomical achievements of that period, amongst which the first attempts to explain the apparent motions of sun, moon, stars, and planets were the most considerable.

We have a complete history of astronomy in the Modern and Classical periods, but there was an earlier astronomy, not inconsiderable in amount, of which no history is preserved. For when Eudoxus commenced his labours, the length of the year had already been determined, the equinoxes and solstices had been recognized, the ecliptic, the celestial equator, and the poles of both great circles were known, and the five principal planets were familiar objects. This Early astronomy must have had its history, its stages of development, but we can only with difficulty trace them out. It cannot have sprung into existence full-grown any more than the other sciences; it must have started from zero, and men must have slowly fought their way from one observation to another, with gradually widening conceptions, before they could bring it even to that stage of development in which it was when the observers of the Museum of Alexandria began their work.

The books of the Old Testament were written at different times during the progress of this Early age of astronomy. We should therefore naturally expect to find the astronomical allusions written from the standpoint of such scientific knowledge as had then been acquired. We cannot for a moment expect that any supernatural revelation of purely material facts would be imparted to the writers of sacred books, two or three thousand years before the progress of science had brought those facts to light, and we ought not to be surprised if expressions are occasionally used which we should not ourselves use to-day, if we were writing about the phenomena of nature from a technical point of view. It must further be borne in mind that the astronomical references are not numerous, that they occur mostly in poetic imagery, and that Holy Scripture was not intended to give an account of the scientific achievements, if any, of the Hebrews of old. Its purpose was wholly different: it was religious, not scientific; it was meant to give spiritual, not intellectual enlightenment.

An exceedingly valuable and interesting work has recently been brought out by the most eminent of living Italian astronomers, Prof. G. V. Schiaparelli, on this subject of "Astronomy in the Old Testament," to which work I should like here to acknowledge my indebtedness. Yet I feel that the avowed object of his book,[7:1]—to "discover what ideas the ancient Jewish sages held regarding the structure of the universe, what observations they made of the stars, and how far they made use of them for the measurement and division of time"—is open to this criticism,—that sufficient material for carrying it out is not within our reach. If we were to accept implicitly the argument from the silence of Scripture, we should conclude that the Hebrews—though their calendar was essentially a lunar one, based upon the actual observation of the new moon—had never noticed that the moon changed its apparent form as the month wore on, for there is no mention in the Bible of the lunar phases.

The references to the heavenly bodies in Scripture are not numerous, and deal with them either as time-measurers or as subjects for devout allusion, poetic simile, or symbolic use. But there is one characteristic of all these references to the phenomena of Nature, that may not be ignored. None of the ancients ever approached the great Hebrew writers in spiritual elevation; none equalled them in poetic sublimity; and few, if any, surpassed them in keenness of observation, or in quick sympathy with every work of the Creator.

These characteristics imply a natural fitness of the Hebrews for successful scientific work, and we should have a right to believe that under propitious circumstances they would have shown a pre-eminence in the field of physical research as striking as is the superiority of their religious conceptions over those of the surrounding nations. We cannot, of course, conceive of the average Jew as an Isaiah, any more than we can conceive of the average Englishman as a Shakespeare, yet the one man, like the other, is an index of the advancement and capacity of his race; nor could Isaiah's writings have been preserved, more than those of Shakespeare, without a true appreciation of them on the part of many of his countrymen.

But the necessary conditions for any great scientific development were lacking to Israel. A small nation, planted between powerful and aggressive empires, their history was for the most part the record of a struggle for bare existence; and after three or four centuries of the unequal conflict, first the one and then the other of the two sister kingdoms was overwhelmed. There was but little opportunity during these years of storm and stress for men to indulge in any curious searchings into the secrets of nature.

Once only was there a long interval of prosperity and peace; viz. from the time that David had consolidated the kingdom to the time when it suffered disruption under his grandson, Rehoboam; and it is significant that tradition has ascribed to Solomon and to his times just such a scientific activity as the ability and temperament of the Hebrew race would lead us to expect it to display when the conditions should be favourable for it.

Thus, in the fourth chapter of the First Book of Kings, not only are the attainments of Solomon himself described, but other men, contemporaries either of his father David or himself, are referred to, as distinguished in the same direction, though to a less degree.

"And God gave Solomon wisdom and understanding exceeding much, and largeness of heart, even as the sand that is on the seashore. And Solomon's wisdom excelled the wisdom of all the children of the east country, and all the wisdom of Egypt. For he was wiser than all men; than Ethan the Ezrahite, and Heman, and Chalcol, and Darda, the sons of Mahol: and his fame was in all nations round about. And he spake three thousand proverbs: and his songs were a thousand and five. And he spake of trees, from the cedar-tree that is in Lebanon even unto the hyssop that springeth out of the wall: he spake also of beasts, and of fowl, and of creeping things, and of fishes. And there came of all people to hear the wisdom of Solomon, from all kings of the earth, which had heard of his wisdom."
