There are many other of these old-time Makers of Medicine of whom nearly the same thing can be said. Basil Valentine is only one of a number of men who worked faithfully and did much both for medical science and professional life during the thousand years from the fall of Rome to the fall of Constantinople, when, according to what used to be commonly accepted opinion, men were not animated by the spirit of research and of fine incentive to do good to men that we are so likely to think of as belonging exclusively to more modern times. A man whom he greatly influenced, Paracelsus, took up the tradition of scientific investigation where Basil Valentine had left it. His work, though more successfully revolutionary, was not done in such a fine spirit of sympathy with humanity nor with that simplicity of life and purity of intention that characterized the old monk's work. Paracelsus' birth in the year of the discovery of America places him among the makers of the foundations of our modern medicine, and he will be treated of in a volume on "The Forefathers in Medicine." APPENDIX I ST. LUKE THE PHYSICIAN[32] In the midst of what has been called the "higher criticism" of the Bible in recent times, one of the long accepted traditions that has been most strenuously assailed and, indeed, in the minds of many scholars, seemed, for a time at least, quite discredited, was that St. Luke the Evangelist, the author of the Third Gospel and the Acts of the Apostles, was a physician. Distinguished authorities in early Christian apologetics have declared that the pillars of primitive Christian history are the genuine Epistles of St. Paul, the writings of St. Luke, and the history of Eusebius. It is quite easy to understand, then, that the attack upon the authenticity of the writings usually assigned to St. Luke, which in many minds seemed successful, has been considered of great importance. In the very recent time there has been a decided reaction in this matter. This has come, not so much from Roman Catholics, who have always clung to the traditional view, and whose great Biblical students have been foremost in the support of the previously accepted opinion, but from some of the most strenuous of the German higher critics, who now appreciate that destructive, so-called higher criticism went too far, and that the traditional view not only can be maintained, but is the only opinion that will adequately respond to all the new facts that have been found, and all the recently gathered information with regard to the relations of events in the olden time.
