The knowledge and observations of these Cullers of simples and Compounders of balsams, if indeed as a rule they really possessed the former, or knew how to make the latter, necessarily perished on their decease, or at best were passed on by tradition to their successors in the doctor’s shops, without professional Physicians or medical Science being one whit advantaged. To such men it was a matter of perfect indifference what was the origin of the disease for which they sold their powders and decoctions, for as _Plato_ (De legg. IV. 720) says, they paid no attention to the existing conditions of disease, and did not care to give a thought to any such thing. But at any rate,—and this was the chief point,—the patient was spared a humiliating confession, and was glad enough to buy the privilege even at the cost of possible ruin to his health. We must further remember that the “filles de joie” in Greece and at Rome were mostly slave-women, who from the very fact of their status could make no claim to treatment by free-born physicians, and that during the flourishing period of Greek medicine under the Hippocratic school it was chiefly persons of the lowest station or else sailors and foreign traders and the like who sought enjoyment in the arms of prostitutes. Such men by their constant change of abode made all continued observation a simple impossibility, so that the very imperfect knowledge possessed by the scientifically trained Physicians with regard to diseases of the genitals and their consequences need occasion little surprise. It is true of course that at the period of universal degradation of morals Physicians must have found no lack of opportunities for observation; but the great majority of them were incapable of utilizing these, actually blocked the way of set purpose, as we shall see presently, that led in the direction of more accurate investigation, or else troubled their heads little about the cultivation of Science or the systematic record of observations. The latter, if they had published them, whether in writing or orally, could only have been detrimental, particularly in the case of physicians of the character of Charidemus’ medical attendant,[277] to their own interests. In fact they were bound to call all their subtlety into play for the express purpose of concealing the true cause of diseases of this type, a circumstance which no doubt we have to thank for a large number of the extravagant and often more than ludicrous statements regarding the origin of Venereal disease in the XVth. and XVIth. Centuries.
