XLIV. (129) 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. (130) And we must understand in the case of every thing else which is decided on by the external senses, there were elder forms and motions previously existing, according to which the things which were created were fashioned and measured out. For although Moses did not describe everything collectively, but only a part of what existed, as he was desirous of brevity, beyond all men that ever wrote, still the few things which he has mentioned are examples of the nature of all, for nature perfects none of those which are perceptible to the outward senses without an incorporeal model.
