gy are neither few nor unworthy of credit, so that there is more reason for investigation than incredulity.[1]
Ah! said Scipio, I wish we had our friend Panætius with us, who is fond of investigating all things of this kind, but especially all celestial phenomena. As for ray opinion, Tubero, for I always tell you just what I think, I hardly agree in these subjects with that friend of mine, since, respecting things of which we can scarcely form a conjecture as to their character, he is as positive as if he had seen them with his own eyes and felt them with his own hands. And I cannot but the more admire the wisdom of Socrates, who discarded all anxiety respecting things of this kind, and affirmed that these inquiries concerning the secrets of nature were either above the efforts of human reason, or were absolutely of no consequence at all to human life.
But, then, my Africanus, replied Tubero, of what credit is the tradition which states that Socrates rejected all these physical investigations, and confined his whole attention to men and manners? For, with respect to him what better authority can we cite than Plato? in many passages of whose works Socrates speaks in such a manner that even when he is discussing morals, and virtues, and even public affairs and politics, he endeavors to interweave, after the fashion of Pythagoras, the doctrines of arithmetic, geometry, and harmonic proportions with them.
That is true, replied Scipio; but you are aware, I believe, that Plato, after the death of Socrates, was induced to visit Egypt by his love of science, and that after that he proceeded to Italy and Sicily, from his desire of understanding the Pythagorean dogmas; that he conversed much with Archytas of Tarentum and Timæus of Locris;
- ↑ This phenomenon of the parhelion, or mock sun, which so puzzled Cicero's interlocutors, has been very satisfactorily explained by modern science. The parhelia are formed by the reflection of the sunbeams on a cloud properly situated. They usually accompany the coronæ, or luminous circles, and are placed in the same circumference, and at the same height. Their colors resemble that of the rainbow; the red and yellow are towards the side of the sun, and the blue and violet on the other. There are, however, coronæ sometimes seen without parhelia, and vice versa. Parhelia are double, triple, etc., and in 1629, a parhelion of five suns was seen at Rome, and another of six suns at Arles, 1666.
