Chapter 17.--Origin of the Legend of the Nine Muses.
27. For we must not listen to the falsities of heathen superstition, which represent the nine Muses as daughters of Jupiter and Mercury. Varro refutes these, and I doubt whether any one can be found among them more curious or more learned in such matters. He says that a certain state (I don't recollect the name) ordered from each of three artists a set of statues of the Muses, to be placed as an offering in the temple of Apollo, intending that whichever of the artists produced the most beautiful statues, they should select and purchase from him. It so happened that these artists executed their works with equal beauty, that all nine pleased the state, and that all were bought to be dedicated in the temple of Apollo; and he says that afterwards Hesiod the poet gave names to them all. It was not Jupiter, therefore, that begat the nine Muses, but three artists created three each. And the state had originally given the order for three, not because it had seen them in visions, nor because they had presented themselves in that number to the eyes of any of the citizens, but because it was obvious to remark that all sound, which is the material of song, is by nature of three kinds. For it is either produced by the voice, as in the case of those who sing with the mouth without an instrument; or by blowing, as in the case of trumpets and flutes; or by striking, as in the case of harps and drums, and all other instruments that give their sound when struck.
Chapter 18.--No Help is to Be Despised, Even Though It Come from a Profane Source.
28. But whether the fact is as Varro has related, or is not so, still we ought not to give up music because of the superstition of the heathen, if we can derive anything from it that is of use for the understanding of Holy Scripture; nor does it follow that we must busy ourselves with their theatrical trumpery because we enter upon an investigation about harps and other instruments, that may help us to lay hold upon spiritual things. For we ought not to refuse to learn letters because they say that Mercury discovered them; nor because they have dedicated temples to Justice and Virtue, and prefer to worship in the form of stones things that ought to have their place in the heart, ought we on that account to forsake justice and virtue. Nay, but let every good and true Christian understand that wherever truth may be found, it belongs to his Master; and while he recognizes and acknowledges the truth, even in their religious literature, let him reject the figments of superstition, and let him grieve over and avoid men who, "when they knew God, glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, and changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things." [1803]

Chapter 19.--Two Kinds Of Heathen Knowledge.
29. But to explain more fully this whole topic (for it is one that cannot be omitted), there are two kinds of knowledge which are in vogue among the heathen. One is the knowledge of things instituted by men, the other of things which they have noted, either as transacted in the past or as instituted by God. The former kind, that which deals with human institutions, is partly superstitious, partly not.
Chapter 20.--The Superstitious Nature of Human Institutions.
30. All the arrangements made by men for the making and worshipping of idols are superstitious, pertaining as they do either to the worship of what is created or of some part of it as God, or to consultations and arrangements about signs and leagues with devils, such, for example, as are employed in the magical arts, and which the poets are accustomed not so much to teach as to celebrate. And to this class belong, but with a bolder reach of deception, the books of the haruspices and augurs. In this class we must place also all amulets and cures which the medical art condemns, whether these consist in incantations, or in marks which they call characters, or in hanging or tying on or even dancing in a fashion certain articles, not with reference to the condition of the body, but to certain signs hidden or manifest; and these remedies they call by the less offensive name of physica, so as to appear not to be engaged in superstitious observances, but to be taking advantage of the forces of nature. Examples of these are the earrings on the top of each ear, or the rings of ostrich bone on the fingers, or telling you when you hiccup to hold your left thumb in your right hand.
31. To these we may add thousands of the most frivolous practices, that are to be observed if any part of the body should jump, or if, when friends are walking arm-in-arm, a stone, or a dog, or a boy, should come between them. And the kicking of a stone, as if it were a divider of friends, does less harm than to cuff an innocent boy if he happens to run between men who are walking side by side. But it is delightful that the boys are sometimes avenged by the dogs; for frequently men are so superstitious as to venture upon striking a dog who has run between them,--not with impunity however, for instead of a superstitious remedy, the dog sometimes makes his assailant run in hot haste for a real surgeon. To this class, too, belong the following rules: To tread upon the threshold when you go out in front of the house; to go back to bed if any one should sneeze when you are putting on your slippers; to return home if you stumble when going to a place; when your clothes are eaten by mice, to be more frightened at the prospect of coming misfortune than grieved by your present loss. Whence that witty saying of Cato, who, when consulted by a man who told him that the mice had eaten his boots, replied, "That is not strange, but it would have been very strange indeed if the boots had eaten the mice."
