14 Now concerning rubbing, Asclepiades as if he were the inventor of the practice has treated it in his volume, entitled "Common aids," at such great length, that, though making mention only of three such aids, namely, Rubbing, Water-drinking, and Rocking, yet he has taken up the greatest part with the first-named subject. Now on such matters recent writers ought to have credit where they have made discoveries, or where they have rightly followed others; yet we must not omit to attribute to their true authors teaching found among the more ancient writers. And it cannot be disputed that Asclepiades has taught when and how rubbing should be practised, with a wider application, and in a clearer way, although he has discovered nothing which had not been comprised in a few words by that most ancient writer Hippocrates, who said that rubbing, if strenuous, hardens the body, if gentle, relaxes; if much, it diminishes, if moderate, fills out. It follows, therefore, that in the following cases rubbing should be employed, when either a feeble body has to be toned up, or one indurated has to be softened, or a harmful superfluity is to be dispersed, or a thin and infirm body has to be nourished. Yet when examined with attention (although this no longer concerns the medical man) the various species of rubbing may be easily recognized as all dependent on causing one thing, depletion. For an object is toned up when that is removed, which, by its presence was the cause of the laxness; and is softened when that which has been producing induration is abstracted; and it is filled up, not by the rubbing itself, but by the nutriment, which subsequently penetrates by some sort of dispersal to the very skin itself after it has become relaxed. The cause of the different results lies in the degree.
