The Roman History · Amm. 21.1.11

Men too, when their hearts are in a state of excitement, foretell the future, but then they are speaking under divine inspiration. For the sun, which is, as natural philosophers say, the mind of the world, and which scatters our minds among us as sparks proceeding from itself, when it has inflamed them with more than usual vehemence, renders them conscious of the future. From which the Sibyls often say they are burning and fired by a vast power of flames; and with reference to these cases the sound of voices, various signs, thunder, lightning, thunderbolts, and falling stars, have a great significance.
