If thus the social condition of the rabbis, who drew no income from their religious duties, induced them to combine the practice of medicine with their pursuits, great facilities had arisen for mental culture through the establishment of so many schools. Henceforth the Jewish physician is recognised as combining with his professional skill a profound knowledge of theology, mathematics, astronomy, philosophy, music, law. In a singular manner he stands aloof in the barbarian societies among whom he lives, looking down like a philosopher upon their idolatries, permitting, or even excusing them, like a statesman. [Sidenote: Writings of the Spanish-Jewish physicians.] Of those who thus adorned the eleventh century was Rabbi Solomon Ben Isaac, better known under the abbreviation Raschi--called by his countrymen the Prince of Commentators. He was equally at home in writing commentaries on the Talmud, or in giving instructions for great surgical operations, as the Cæsarean section. He was the greatest French physician of his age. Spain during the same century, produced a worthy competitor to him, Ebn Zohr, physician to the court of Seville. His writings were in Hebrew, Arabic, Syriac, and both in prose and verse. He composed a treatise on the cure of diseases, and two on fevers. In singular contrast with the superstitious notions of the times, he possessed a correct view of the morbific nature of marsh miasm. He was followed by Ben Ezra, a Jew of Toledo, who was at once a physician, philosopher, mathematician, astronomer, critic, poet. He travelled all over Europe and Asia, being held in captivity for some time in India. Among his medical writings was a work on theoretical and practical medicine, entitled "Book of Proofs." Through the wars arising in Spain between the Mohammedans and Christians, many learned Jews were driven into France, imparting to that country, by their presence, a new intellectual impulse. Of such were Aben Tybbon, who gave to his own profession a pharmaceutical tendency by insisting on the study of botany and art of preparing drugs. Ben Kimchi, a Narbonnese physician and grammarian, wrote commentaries on the Bible, sacred and moral poems, a Hebrew grammar. Notwithstanding the opposition of the ecclesiastics, William, the Lord of Montpellier, passed an edict authorizing all persons, without exception, to profess medicine in the university of his city. This was specially meant for the relief of the Jews, though expressed in a general way. [Sidenote: Maimonides.] Spain, though she had thus lost many of her learned men, still continued to produce others of which she had reason to be proud. Moussa Ben Maimon, known all over Europe as Maimonides, was recognized by his countrymen as "the Doctor, the Great Sage, the Glory of the West, the Light of the East, second only to Moses." He is often designated by the four initials R. M. B. M., that is Rabbi Moses Ben Maimon, or briefly Rambam. His biography presents some points of interest.
