Res Gestae

And although very many writers flourished in early times as well as these whom I have mentioned, nevertheless not even to-day is learning of various kinds silent in that same city; for the teachers of the arts show signs of life, and the geometrical measuring-rod brings to light whatever is concealed, the stream of music is not yet wholly dried up among them, harmony is not reduced to silence, the consideration of the motion of the universe and of the stars is still kept warm with some, few though they be, and there are others who are skilled in numbers; and a few besides are versed in the knowledge which reveals the course

Moreover, studies in the art of healing, whose help is often required in this life of ours, which is neither frugal nor sober, are so enriched from day to day, that although a physician’s work itself indicates it, yet in place of every testimony it is enough to commend his knowledge of the art, if he has said that he was trained at Alexandria.

But enough on this point. If one wishes to investigate with attentive mind the many publications on the knowledge of the divine, and the origin of divination, he will find that learning of this kind has been spread abroad from Egypt through the whole world,

There, for the first time, long before other men, they discovered the cradles, so to speak, of the various religions, and now carefully guard the first beginnings of worship, stored up in secret writings.
