sun's brightness upon the clouds, and reproducing the brightness of its circle from them. Now this does not always take place, but only when the opportunity is presented by the rarefaction of moistened clouds. And consequently, when the clouds again are condensed and unite, the form of the bow is dissolved and vanishes. Finally, the bow never is seen without sun and clouds, just as the image is not produced, unless there be the type, and wax, or some other material. Nor is it wonderful if God the Creator in the beginning made types, from which forms and species may now be expressed. But this is similar to that, that in the beginning God created insensible elements, which He might use for forming and developing all other things. But even those who form statues, first make a mould of clay or wax, and from it the figure of the statue is produced. And then afterwards a shadow is also produced from the statue, which shadow always bears the form and likeness of the statue. What shall we say then? That the insensible statue forms a shadow finished with as diligent care as the statue itself? Or shall the finishing of the shadow be unhesitatingly ascribed to him who has also fashioned the statue?
Chap. xliii.—Things apparently useless and vile made by God.
"If, then, it seems to you that this is so, and what has been said on this subject is enough, let us come to inquire into other matters; or if you think that something is still wanting, let us go over it again." And the old man said: "I wish you would go over this again, since there are many other things which I see to be made in like manner: for both the fruits of trees are produced in like manner, beautifully formed and wonderfully rounded; and the appearance of the leaves is formed with immense gracefulness, and the green membrane is woven with exquisite art: then, moreover, fleas, mice, lizards, and such like, shall we say that these are made by God? Hence, from these vile objects a conjecture is derived concerning the superior, that they are by no means formed by the art of mind." "You infer well," said Aquila, "con-
