And in the "Apollonius of Tyana" by Philostratus, when Apollonius wishes to prove an alibi, he calls to witness the physicians of his sick friend, Seleucus and Straloctes, who were accompanied by their clinical class to the number of about thirty students.(34) But for a first-hand sketch of the condition of the profession we must go to Pliny, whose account in the twenty-ninth book of the "Natural History" is one of the most interesting and amusing chapters in that delightful work. He quotes Cato's tirade against Greek physicians,--corrupters of the race, whom he would have banished from the city,--then he sketches the career of some of the more famous of the physicians under the Empire, some of whom must have had incomes never approached at any other period in the history of medicine. The chapter gives a good picture of the stage on which Galen (practically a contemporary of Pliny) was to play so important a role. Pliny seems himself to have been rather disgusted with the devious paths of the doctors of his day, and there is no one who has touched with stronger language upon the weak points of the art of physic. In one place he says that it alone has this peculiar art and privilege, "That whosoever professeth himself a physician, is straightwaies beleeved, say what he will: and yet to speake a truth, there are no lies dearer sold or more daungerous than those which proceed out of a Physician's mouth. Howbeit, we never once regard or look to that, so blind we are in our deepe persuasion of them, and feed our selves each one in a sweet hope and plausible conceit of our health by them. Moreover, this mischief there is besides, That there is no law or statute to punish the ignorance of blind Physicians, though a man lost his life by them: neither was there ever any man knowne, who had revenge of recompence for the evill intreating or misusage under their hands. They learne their skill by endaungering our lives: and to make proofe and experiments of their medicines, they care not to kill us."(35) He says it is hard that, while the judges are carefully chosen and selected, physicians are practically their own judges, and that of the men who may give us a quick despatch and send us to Heaven or Hell, no enquiry or examination is made of their quality and worthiness. It is interesting to read so early a bitter criticism of the famous "Theriaca," a great compound medicine invented by Antiochus III, which had a vogue for fifteen hundred years. (34) Bk. VIII, Chap.
