Moreover, they say that all these fiery bodies, and all the other stars, receive nutriment; the sun from the vast sea, being a sort of intellectual appendage; and the moon from the fresh waters, being mingled with the air, and also near the earth, as Posidonius explains it in the sixth book of his Discourses on Natural Philosophy. And all the other stars derive their nourishment from the earth. They also consider that the stars are of a spherical figure, and that the earth is immovable. And that the moon has not a light of her own, but that she borrows it from the sun. And that the sun is eclipsed, when the moon runs in front of it on the side towards us, as Zeno describes in his work on the Universe; for when it comes across it in its passage, it conceals it, and again it reveals it; and this is a phenomenon easily seen in a basin of water. And the moon is eclipsed when it comes below the shadow of the earth, on which account this never happens, except at the time of the full moon; and although it is diametrically opposite to the sun every month, still it is not eclipsed every month, because when its motions are obliquely towards the sun, it does not find itself in the same place as the sun, being either a little more to the north, or a little more to the south. When therefore it is found in the same place with the sun, and with the other intermediate objects, then it takes as it were the diameter of the sun, and is eclipsed. And its place is along the line which runs between the crab and the scorpion, and the ram and the bull, as Posidonius tells us. LXXII. They also say that God is an animal immortal, rational, perfect, and intellectual in his happiness, unsusceptible of any kind of evil, having a foreknowledge of the world and of all that is in the world; however, that he has not the figure of a man; and that he is the creator of the universe, and as it were, the Father of all things in common, and that a portion of him pervades everything, which is called by different names, according to its powers; for they call him Δία as being the person (δι’ ὃν) everything is, and Ζῆνα, inasmuch as he is the cause of life, (τοῦ Ζῆν), or because he pervades life. And Ἀθηνᾶ, with reference to the extension of his dominant power over the æther (εἰς αἰθέρα). And Ἥρα, on account of his extension through the air (εἰς ἀέρα). And Ἥφαιστος, on account of his pervading fire, which is the chief instrument of art; and Ποσειδῶν, as pervading moisture, and Δημήτηρ, as pervading the earth (Γῆ). And in the same way, regarding some other of his peculiar attributes, they have given him other names.[91]
