47. You have demanded fifteen slaves to support an accusation of magic; how many would you be demanding if it were a charge of violence? The inference is that fifteen slaves know something, and that something is still a mystery. Or is it nothing mysterious and yet something connected with magic? You must admit one of these two alternatives: either the proceeding to which I admitted so many witnesses had nothing improper about it, or, if it had, it should not have been witnessed by so many. Now this magic of which you accuse me is, I am told, a crime in the eyes of the law, and was forbidden in remote antiquity by the Twelve Tables because in some incredible manner crops had been charmed away from one field to another. It is then as mysterious an art as it is loathly and horrible; it needs as a rule night-watches and concealing darkness, solitude absolute and murmured incantations, to hear which few free men are admitted, not to speak of slaves. And yet you will have it that there were fifteen slaves present on this occasion. Was it a marriage? or any other crowded ceremony? or a seasonable banquet? Fifteen slaves take part in a magic rite as though they had been created _quindecimvirs_ for the performance of sacrifice! Is it likely that I should have permitted so large a number to be present on such an occasion, if they were too many to be accomplices? Fifteen free men form a borough, fifteen slaves a household, fifteen fettered serfs a chain-gang. Did I need such a crowd to help me by holding the lustral victims during the lengthy rite? No! the only victims you mentioned were hens! Were they to count the grains of incense? or to knock Thallus down?
