30. All the arrangements made by men to 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.
