Though so much nearer in time medieval medicine seems much farther away from us than is Greek medicine. Most of us are quite sure that the impression of distance is due to its almost total lack of significance. It is with the idea of showing that the medieval generations, as far as was possible in their conditions, not only preserved the old Greek medicine for us in spite of the most untoward circumstances, but also tried to do whatever they could for its development, and actually did much more than is usually thought, that this story of "Old-Time Makers of Medicine" is written. It represents a period--that of the Middle Ages--that is, or was until recently, probably more misunderstood than any other in human history. The purpose of the book is to show at least the important headlands that lie along the stream of medical thought during the somewhat more than a thousand years from the fall of the Roman Empire under Augustulus (476) until the discovery of America. After that comes modern medicine, for with the sixteenth century the names and achievements of the workers in medicine are familiar--Paracelsus, Vesalius, Columbus, Servetus, Caesalpinus, Eustachius, Varolius, Sylvius are men whose names are attached to great discoveries with which even those who are without any pretence to knowledge of medical history are not unacquainted. In spite of nearly four centuries of distance in time these men seem very close to us. Their lives will be reserved for a subsequent volume, "Our Forefathers in Medicine."
