The Hellenizing Jewish physicians inoculated the Arabs with learning on their first meeting with them in Alexandria, obtaining a private and personal influence with many of khalifs, and from that central point of power giving an intellectual character to the entire Saracenic movement. We have already seen that in this they were greatly favoured by the approximation of their unitarianism to that of the Mohammedans. The intellectual activity of the Asiatic and African Jews soon communicated an impulse to those of Europe. The Hebrew doctor was viewed by the vulgar with wonder, fear, and hatred; no crime could be imputed to him too incredible. Thus Zedekias, the physician to Charles the Bald, was asserted to have devoured at one meal, in the presence of the court, a waggon-load of hay, together with its horses and driver. [Sidenote: Writings of Jewish physicians.] The titles of some of the works that appeared among them deserve mention, as displaying a strong contrast with the mystical designations in vogue. Thus Isaac Ben Soleiman, an Egyptian, wrote "On Fevers," "On Medicine," "On Food and Remedies," "On the Pulse," "On Philosophy," "On Melancholy," "An Introduction to Logic." The simplicity of these titles displays an intellectual clearness and a precision of thought which have ever been shown by the Israelites. They are in themselves sufficient to convince us of the strong common sense which these men were silently infusing into the literature of Western Europe in ages of concealment and mystification. Roger Bacon, at a much later time, gave to one of his works the title of "The Green Lion;" to another, "The Treatise of Three Words." Since it was by the power and patronage of the Saracens that the Jewish physicians were acting, it is not surprising that the language used in many of their compositions was Arabic. Translations were, however, commonly made into Hebrew, and, at a subsequent period, into Latin. Through the ninth century the Asiatic colleges maintained their previous celebrity in certain branches of knowledge. Thus the Jew Shabtai Donolo was obliged to go to Bagdad to complete his studies in astronomy. [Sidenote: Foundation of colleges.] As Arabian influence extended itself into Sicily and Italy, Jewish intelligence accompanied it, and schools were founded at Tarentum, Salerno, Bari, and other places. Here the Arab and Jew Orientalists first amalgamated with a truly European element--the Greek--as is shown by the circumstance that in the college at Salerno instruction was given through the medium of all three languages. At one time, Pontus taught in Greek, Abdallah in Arabic, and Elisha in Hebrew. A similar influence of the Arab and Jew combined founded the University of Montpellier.
