It would doubtless appear strange to most readers of this brief sketch of the history of medicine if some reference were not made in this place to Luke, the author of the gospel which bears his name and of the Acts of the Apostles, and who was also the companion of Paul on his journey to Rome and during a portion of the latter’s stay in that city. Luke was a native of Antioch, in Syria, and not a Jew. He was a physician and tradition says that he was also a painter. It is not known where he received his medical training, but it is not at all unlikely that he studied at Alexandria, in Egypt, where the greatest facilities for such training, obtainable at that period, were to be found. His style of writing shows plainly that he was a man of considerable cultivation and endowed with a clear and logical mind; and if he had not possessed a genial personality he would hardly have been known as “the beloved physician”; nor could any other motive but those of loyal, self-sacrificing friendship for his friend, and a desire to promote the cause of Christianity, have led him to share with Paul the dangers and discomforts of the journey to Rome. _The Medicine of India, China and Japan._--It would be too much of a departure from the plan which is being followed in the writing of this history to attempt to describe, even in the briefest manner, the mode of development of the science and art of medicine in India, China and Japan. Unquestionably the earlier physicians of these countries made many valuable contributions to medical knowledge, but they were made at such a period of time, or under such conditions, that they could not have exerted an appreciable influence upon the development of medicine in ancient Greece,--certainly no such influence as was exerted by Assyria and Persia, and especially by Egypt. It therefore seems permissible to speak of the medicine of these more remote countries only incidentally, and not as an integral part of the series of centres of learning which made the medicine of ancient Greece the direct ancestor--if I may use such a term--of European medicine.[11] In conformity with this idea it will be well to mention here briefly a few of the more important facts relating to the achievements of the physicians of the three countries named. The most celebrated medical authors in India were Caraka, Súsruta and Vagbhata--“The ancient trinity,” as they were called. Caraka probably lived during the early part of the Christian era, Súsruta during the fifth century, and Vagbhata not later than during the seventh century A. D. It is apparent, therefore, that none of the treatises written by these authors could have exerted the slightest influence upon the growth of medical knowledge in ancient Greece.
