Note 1374 — BOOK VII.835 MAN, HIS BIRTH, HIS ORGANIZATION, AND THE INVENTION OF THE ARTS. (continued 2)

There has been much discussion respecting the interpretation of this passage. In the first place, the numbers in the text have extended from 720 and 490 to as many thousands, by the addition of the letter M., against the authority, however, of some MSS. In the next place, in order to curtail the enormous periods thus formed, the years have been supposed to be only lunar, or even diurnal periods. The opinion of Hardouin and Marcus is perhaps the better founded, who reject the proposed alteration, and consider these numbers to indicate, according to their natural signification, periods of years. The principal consideration that has been urged in favour of the alteration of the text is derived from two passages in Cicero’s Treatise de Divin. B. i. c. 19, and B. ii. c. 46, where he refers to the very long periods which the Babylonians employed in their calculations, but which he justly regards as entirely without foundation, and even ridiculous. Pliny, however, professes to follow the opinion of Epigenes whom he styles “gravis auctor,” and who, we may premise, would reject these improbable tales.—B. The reading, 720 thousands, is the one adopted by Sillig.
