De Plantatione

And the statement that "the Paradise was in the east," is a proof of what has been here said. For folly is a thing of darkness and setting, and which brings on the night; but wisdom is a most brilliant thing, radiant all around, and in the truest sense of the word, rising. And, as the sun, when it arises, fills the whole circle of the heaven with its light, so in the same manner, when the beams of virtue shine forth, they made the whole place occupied by the mind full of pure light.
