With all this activity in Egypt, it is easy to understand that the other great nations of antiquity also have important chapters in the history of medicine. The earliest accounts would seem to indicate that the Chaldeans, the Assyrians and the Babylonians all made significant advances in medicine. It seems clear that a work on anatomy was written in China about the year 2000 B.C. Some of the other Eastern nations made great progress. The Hindoos in particular have in recent years been shown to have accomplished very good work in medicine itself. Charaka, a Hindu surgeon, who lived not later than 300 B.C., made some fine contributions to the medical literature in Hindostani. There were hospitals in all these countries, and these provided opportunities for the practice of surgery. Laparotomy was very commonly done by Hindu surgeons, and one of the rules enjoined by Hindu students was the constant habit of visiting the sick and seeing them treated by experienced physicians. Clinical teaching is often spoken of as a modern invention, but it is as old as hospital systems, and they go back to the dawn of history. It is among the Greeks, however, that the most {365} important advances in medicine, so far as we are concerned, were made. This is, however, not so much because of what they did as from the fact that they were more given to writing, and then their writings have been better preserved for us than those of other nations. The first great physician among the Greeks was AEsculapius, of whom, however, we have only traditions. He is fabled to have been the son of Apollo, the god of music and the arts, and therefore to have been a near relative of the Muses. The connection is rather interesting, because sometimes people try to remove medicine from among the arts that minister to the happiness of man, and place it among the sciences whose application is for his profit. Medicine still remains an art, however. The temples of AEsculapius were the first hospitals, though the priests were not the only ones who practised medicine, for there were laymen who, after having served for some time in the hospitals, wandered through the country under the name of Asclepiads, treating people who were not able to go to the hospitals or shrines. These evidently, then, were the first medical schools in Greece as well as the first hospitals.
