what he thought he ought to do, regardless of the devious ways of men, even those whom he was generously assisting. While we do not know much of his scientific medicine, we do know that he was a fine example of a practitioner of medicine on the highest professional lines.

With the foundation of the school at Djondisabour in Arabistan or Khusistan by the Persian monarch Chosroes, some Jewish physicians come into prominence as teachers, and this is one of the first important occasions in history when they teach side by side with Christian colleagues. Djondisabour seems distant from us now, lying as it does in the province just above the head of the Persian Gulf, and it is a little hard to understand its becoming a centre of culture and education, yet aceording to wellgrounded historical traditions students flocked here from all parts of the world, and its medical instruction particularly became famous. According to the documents and traditions that we possess, clinical teaching was the most significant feature of the school work and made it famous. As a consequence graduates from here were deemed fully qualified to become professors in other institutions and were eagerly sought by various medical schools in the East.

With the rise of the strong political power of the Mohammedans enough of peace came to the East at least to permit the cultivation of arts and sciences to some extent again, and then at once the eminence of Jewish physicians, both as teachers and practitioners of medicine, once more becomes manifest. The first of the race who comes into prominence is Maser Djawah Ebn Djeldjal, of Basra. To him we owe probably more than to anyone else the preservation of old scientific writings and the cultivation of arts and sciences by the Mohammedans. He prevailed on Caliph Moawia I, whose physician he had become, to cause many foreign works, and especially those written in Greek, to be translated into Arabic. He seems to have taken a large share of the labor of the translation on himself and prevailed upon his pupil, the son of Moawia, to translate some works on chemistry. The translation for which Maser Djawah is best known is that of the Pandects of Haroun, a physician of Alexandria. The translation of this work was made toward the end of the seventh century. Unfortunately the “ Pandects” has not come down to us, either in original or translation, but we have fragments of the translation preserved by Rhazes, the distinguished Arabian medical writer and physician of the ninth century, and there seems no doubt that it contained the first good description of smallpox, a chapter in medicine that is often—though incorrectly-attributed to Rhazes himself. Rhazes quoted Maser Djawah freely and evidently trusted his declarations implicitly.

The succeeding Caliphs of the first Arabian dynasty did not exhibit the same interest in education, and above all in science, that characterized Moawia. Political ambition and the desire for military glory seem to have filled up their thoughts and perhaps they had not the good fortune to fall under the influence of physicians so wise and learned as Maser Djawah. More probably, however, they themselves lacked interest. Toward the end of the seventh century they were succeeded by the Abbassides. Almansor, the second Caliph of this dynasty, was attacked by a dangerous disease and sent for a physician of the Nestorian school. After his restoration to health he became a liberal patron of science and especially medical science. The new city of Bagdad, which had become the capital of the realm of the Abbassides, was enriched by him with a large number of works on medicine, which he caused to be translated from the Greek. He did not confine limself to medicine, however, but also brought about translations of works with regard to other sciences. One of these, astronomy, was a favorite. Le made it a particular point to seareh out and encourage the translation of such books as had not previously been translated from Greek into Arabic. While be provided a translation of Ptolemy be also had translations made of Aristotle and Galen.

It is not surprising, then, that the sehool of Bagdad became celebrated. Jewish physicians seem to have been most prominent in its foundation, and the most distinguished product of it is Isaac Ben Emran, almost as celebrated as a philosopher as he is as a pbysician. One of his expressions with regard to the danger of a patient having two physicians whose opinions disagree with regard to his illness has been deservedly preserved for us. Zeid, an Emir of one of the chief cities of the Arabs in Barbary, fell ill of a tertian fever and called Isaac and another physician in consultation. Their opinions were so widely in disaccord that Isaac refused to prescribe anything, and when the Emir, who had great confidence

in him, demanded the reason, he replied, “ disagreement of two physicians is more deadly than a tertian fever." This Isaac, who is said to have died in 799, is the great Jewish physician, one of the most important members of the profession in the eighth century. His principal work was with regard to poisons and the symptoms caused by them. This is often quoted by medical writers in the after time.

The prominent Jewish physician of the ninth century was Joshua Ben Nun. Haroun al-Raschid, whose attempts to secure justice for his people are the subject of so much legendary lore, and whose place in history may be best recalled by the fact that he is a contemporary of Charlemagne, was particularly interested in medicine. He founded the city of Tauris as a memorial of the cure of his wife. He was a generous patron of the school of Djondisabour and established a medical school also at Bagdad. He provided good salaries for the professors, insisted on careful examinations, and raised the standard of medical education for a time to a noteworthy degree. The greatest teacher of this school at Bagdad was Joshua Ben Nun, sometimes known as the Rabbi of Seleucia. His teaching attracted many students to Bagdad and his fame as one of the great practitioners of medicine of this time brought many patients. Among his disciples was John Masuée, whose Arabian name is so different, Yahia Ben Masoviah, that in order to avoid confusion in reading it is important to know both. Almost better known, perhaps, at this time was Abu Joseph Jacob Ben Isaac Kendi. Fortunately for the after time, these men devoted themselves not only to their own observations and writings bat made a series of valuable translations. Joshua Bez Nu seems to have been particularit zealous in this matter, following the exam of Maser Djawahof Basra.

Bagdad then became a centre for Arabian culture. Mahmond, one oi Haroun 's successors, provided in Bagdad a petuge for the learned men of the East yo were disturbed by the wars and troubles of the time. He became a libera patron of literature and education. When the Emperor Michael III of Coustantinople was conquered in battle, one of the obligations imposed upon lub was to send many camel loads of books to Bagdad, and Aristotle and Plato were studied devotedy and translated into Arabic. The era of eulture affected not only the capital but all the cities, and everywbere throughont the Arabian empire schools and academies sprang up. We have records of tuem at Basra, Samarcand, Ispahan. From here the thirst for education spread to the other cities ruled by the Mohammedans, and each town became affected by it. Alexandria, the cities of the Barbary States, those of Sicily and Provence, where Moorish influences were prominent, and of distant Spaili, Cordova, Sevilie, Toledo, Granada, Saragossa, all took up the rivalry for culture which made this a glorious period in the history of the intellectual life.

Already, in the chapter on “ Great Physicians in Lariy Christian Times,” I have pointed out that many of the teachers of the Arabs were Christian physicians. Here it is proper to emphasize the other important factor in Arabian medicine, the Jewish physicians, who influenced the great Arabian rulers,
