The physicians who practised dietetics were like our consultants, only more so. They were above all things philosophers, the recognised successors of the Greek thinkers and theorists, and but too often their imitators. Although they owed their designation to their general authority on régime, they prescribed and invented medicines. The pharmaceutical section came to be called in Latin medicamentarii, and their history corresponds closely with that of our English apothecaries. At first they prepared and administered the medicines which the physicians ordered. But in Alexandria and Rome they gradually assumed the position of general practitioners. To another class, designated by Pliny Vulnerarii, was left the treatment of wounds, and probably of tumours and ulcers. The necessity of a lower grade of medical practitioners in Rome is manifest from a remark of Galen’s to the effect that no physician, meaning a person in his own rank, would attend to diseases of minor importance. It is worthy of note that the Latin designation medicamentarius, which was nearly equivalent to the Greek pharmacopolis, was similarly used to mean a poisoner, while pharmakon in Greek and medicamentus in Latin might mean either a medicine or a poison. It is noted elsewhere (page 52) that the word pharmakeia when it occurs in the New Testament is universally translated in our versions by the term sorcery or some similar word. At the time when the Apostles wrote this was evidently the prevalent meaning attached to the term. But in earlier Greek literature the reputable and the disgraceful ideas associated with the word seem to have run side by side for centuries. Homer uses pharmakon in both senses; Plato makes pharmakeuein mean to administer a remedy, while Herodotus adopts it to signify the practice of sorcery. Apparently this word came from an earlier, pharmassein, which was derived from a root implying to mix, and the gradual sense development was that of producing an effect by means of drugs. They might produce purging, they might produce a colour, or they might produce love. The multiplication of names for the various classes connected with medicine and pharmacy in the Roman world is rather confusing. As the language of medicine up to and including Galen was largely Greek, many of the designations employed were those which had been drawn from that tongue. The name Pharmacopeus, used in Greek to denote certain handlers of drugs, had always a sinister signification. It suggested a purveyor of noxious drugs, a compounder of philtres, a vendor of poisons. The men who kept shops for the sale of drugs generally were called pharmacopoloi. This term was not free from reproach, because it was a common appellation, not only of the shopkeepers strictly so-called, but was also applied to the periodeutes, or agyrtoi, travelling quacks or assembly gatherers, or as they came to be named in Latin, circulatores or circumforanei.
