[129] [cap.44] So Moses, summing up his account of the creation of the world, says in a brief style, “This is the book of the creation of the heaven and of the earth, when it took place, in the day on which God made the heaven and the earth, and every green herb before it appeared upon the earth, and all the grass of the field before it sprang up.” Does he not here manifestly set before us incorporeal ideas perceptible only by the intellect, which have been appointed to be as seals of the perfected works, perceptible by the outward senses. For before the earth was green, he says that this same thing, verdure, existed in the nature of things, and before the grass sprang up in the field, there was grass though it was not visible.
