City of God: Chapter 11

Chapter 11.—Concerning the Surnames of Jupiter, Which are Referred Not to Many Gods, But to One and the Same God.

They have called him Victor, Invictus, Opitulus, Impulsor, Stator, Centumpeda, Supinalis, Tigillus, Almus, Ruminus, and other names which it were long to enumerate.  But these surnames they have given to one god on account of diverse causes and powers, but yet have not compelled him to be, on account of so many things, as many gods.  They gave him these surnames because he conquered all things; because he was conquered by none; because he brought help to the needy; because he had the power of impelling, stopping, stablishing, throwing on the back; because as a beam 272 he held together and sustained the world; because he nourished all things; because, like the pap, 273 he nourished animals.  Here, we perceive, are some great things and some small things; and yet it is one who is said to perform them all.  I think that the causes and the beginnings of things, on account of which they have thought that the one world is two gods, Jupiter and Janus, are nearer to each other than the holding together of the world, and the giving of the pap to animals; and yet, on account of these two works so far apart from each other, both in nature and dignity, there has not been any necessity for the existence of two gods; but one Jupiter has been called, on account of the one Tigillus, on account of the other Ruminus.  I am unwilling to say that the giving of the pap to sucking animals might have become Juno rather than Jupiter, especially when there was the goddess Rumina to help and to serve her in this work; for I think it may be replied that Juno herself is nothing else than Jupiter, according to those verses of Valerius Soranus, where it has been said:

“Almighty Jove, progenitor of kings, and things, and gods,

And eke the mother of the gods,” etc.

Why, then, was he called Ruminus, when they who may perchance inquire more diligently may find that he is also that goddess Rumina?

If, then, it was rightly thought unworthy of the majesty of the gods, that in one ear of corn one god should have the care of the joint, another that of the husk, how much more unworthy of that majesty is it, that one thing, and that of the lowest kind, even the giving of the pap to animals that they may be nourished, should be under the care of two gods, one of whom is Jupiter himself, the very king of all things, who does this not along with his own wife, but with some ignoble Rumina (unless perhaps he himself is Rumina, being Ruminus for males and Rumina for females)!  I should certainly have said that they had been unwilling to apply to Jupiter a feminine name, had he not been styled in these verses “progenitor and mother,” and had I not read among other surnames of his that of Pecunia [money], which we found as a goddess among those petty deities, as I have already mentioned in the fourth book.  But since both males and females have money [pecuniam], why has he not been called both Pecunius and Pecunia?  That is their concern.
