Lælius. “Let us rather hear you, unless Manilius thinks, that some decree by way of compromise between these two suns may be adjusted; so that each may keep possession of its own part of the firmament.” “You love still to banter that science, Lælius, in which I am proud to excel,” replied Manilius, “and without which no one could know his own possession from anothers. But of that by and by. Let us now listen to Philus, who I perceive has a case of greater difficulty referred to him, than ever came before me or P. Mucius.”
XIV. “I shall lay nothing new before you,” said Philus, “nor any thing discovered or thought of by myself. I remember, however, that C. Sulpicius Gallus, a very learned man as you know; when this same phenomenon was stated to have been seen, being by chance in the house of M. Marcellus, who had been in the consulate with him; ordered a sphere to be placed before him, which the ancestor of M. Marcellus had taken from the conquered Syracusans, and brought out of their wealthy and embellished city; the only thing he had possessed himself of among so great a spoil. I had heard a great deal of this sphere, on account of the fame of Archimedes, but did not admire the construction of it so much; for another which Archimedes also had made, and which the same Marcellus had placed in the temple of virtue, was more elegant and remarkable in the general opinion. But subsequently, when Gallus began very scientifically to explain the nature of the mechanism; the Sicilian appeared to me to possess more genius, than human nature would seem to be capable of. Gallus said, that the other solid and full sphere was an old invention, and was first wrought by Thales of Miletas: but afterwards was delineated over with the fixed stars in the heavens by Eudoxus, the Cnidian, a disciple of Plato. The which adorned and embellished as it was by Eudoxus, Aratus who had no knowledge of astronomy, but a certain poetical faculty, many years afterwards extolled in his verses. The mechanism of this sphere, however, on which the motions of the sun, moon, and those five stars which are called wandering and irregular, are shown; could not be illustrated on that solid sphere. But what appeared very admirable in this invention of Archimedes was, that he had discovered a method of producing the unequal and various courses, with their dissimilar velocities, by one revolution. When Gallus put this sphere in motion, the moon was made to succeed the sun by as many revolutions of the brass circle, as it actually took days to do in the heavens. From which the same setting of the sun was produced on the sphere as in the heavens: and the moon fell on the very point, where it met the shadow of the earth, when the sun from the region * * * *

I remember when I was but a boy, being with my father, who was then consul in Macedonia; that while we were encamped, our army was struck with a religious dread, because the full and splendid moon in the serenity of the night, was suddenly eclipsed. He being then our lieutenant, the year just before that in which he was declared consul, did not hesitate the following day, to pronounce openly in the camp, that it was no prodigy. And that what had then taken place, would always occur in future at those particular periods, when the position of the sun was such, that its rays could not fall upon the moon. “But how could he,” asked Tubero, “make men half wild, comprehend such matters, or venture to speak of them before the unenlightened?”

XVI. There was an occurrence similar to this during the great war, which the Athenians and Lacedemonians waged against each other with so much inveteracy. Darkness being suddenly produced by the obscuration of the sun, and a prodigious fear taking possession of the minds of the Athenians. Pericles, the first man in the city, in authority, in eloquence, and in council; taught the citizens what he had himself learnt from Anaxagoras, whose pupil he had been: that it was an unavoidable appearance at the particular period, when the moon had placed herself immediately before the orb of the sun: and although it did not take place every lunar period; it could nevertheless be occasioned only by the moon’s motion. Having convinced them by reasoning, he delivered the people from their apprehension. For it was then a strange and unknown reason to give for an eclipse, that the sun and moon were in opposition to each other, which it is said, was first observed by Thales the Milesian. At a later period, this had not escaped our Ennius, who wrote about the year 350 of the building of Rome, in the nones of June; that “the moon and night stood before the sun.” So great, however, is the advancement of knowledge in these matters, that from this day, which we find noted in the principal annals, and by Ennius; the previous occultations of the sun are fixed up to that which took place in the reign of Romulus, in the nones of the fifth month. During which darkness, Romulus, whom the laws of nature indeed would have carried to the tomb, is said to have been borne by his virtue to heaven.
