Certain writers seek for a rational explanation of this practice. One school, adopting the only line that comports with philosophy, deny the possibility of making any bargain with hail and buying off storms by paltry presents, true, though it be, that gifts overcome even gods. Others affirm their suspicion that blood itself contains a virtue potent enough to avert and repel a cloud. But how, I ask, should a drop or two of blood possess a virtue to reach on high and influence the clouds? Is it not much easier to say, the whole thing is a parcel of lies? But Cleonae was strict in dealing with its warders who had received charge of looking out beforehand for the storm, if it happened that through their neglect the vineyards had been beaten down or the crops laid. And among ourselves, too, at Rome the laws of the Twelve Tables introduce safeguards against the blighting of a neighbour’s crops by charms. Antiquity as yet untutored entertained the belief that rain could be attracted or repelled by incantations. The impossibility of such fancies is so evident that one need not enter a school of philosophy in order to be taught how to disprove them.
