33 Furthermore observe from what follows that God did not take thought for the Hebrews alone, but though he cared for all nations, he bestowed on the Hebrews nothing considerable or of great value, whereas on us he bestowed gifts far higher and surpassing theirs. For instance the Egyptians, as they reckon up the names of not a few wise men among themselves, can boast that they possess many successors of Hermes, I mean of Hermes who in his third manifestation visited Egypt; while the Chaldaeans and Assyrians can boast of the successors of Oannes and Belos; the Hellenes can boast of countless successors of Cheiron. For thenceforth all Hellenes were born with an aptitude for the mysteries and theologians, in the very way, you observe, which the Hebrews claim as their own peculiar boast. . . .
34 But has God granted to you to originate any science or any philosophical study? Why, what is it? For the theory of the heavenly bodies was perfected among the Hellenes, after the first observations had been made among the barbarians in Babylon. And the study of geometry took its rise in the measurement of the land in Egypt, and from this grew to its present importance. Arithmetic began with the Phoenician merchants, and among the Hellenes in course of time acquired the aspect of a regular science. These three the Hellenes combined with music into one science, for they connected astronomy with geometry and adapted arithmetic to both, and perceived the principle of harmony in it. Hence they laid down the rules for their music, since they had discovered for the laws of harmony with reference to the sense of hearing an agreement that was infallible, or something very near to it.
