Mention of the well-known fact that the Hebrew studies prosecuted by Christians in the eighteenth century were carried on under Jewish influence brings us to the threshold of the modern era, the period of the Jewish Renaissance. Here we are on well-worn ground. Since Jews have been permitted to enter at will upon the multifarious pursuits growing out of modern culture, their importance as factors of civilization is universally acknowledged, and it would be wearisome, and would far transgress the limits of a lecture, to enumerate their achievements. In trying to show what share the Jew has had in the world's civilization, I have naturally concerned myself chiefly with literature, for literature is the mirror of culture. It would be a mistake, however, to suppose that the Jew has been inactive in other spheres. His contributions, for instance, to the modern development of international commerce, cannot be overlooked. Commerce in its modern extension was the creation of the mercantile republics of mediæval Italy-Venice, Florence, Genoa, and Pisa--and in them Jews determined and regulated its course. When Ravenna contemplated a union with Venice, and formulated the conditions for the alliance, one of them was the demand that rich Jews be sent thither to open a bank for the relief of distress. Jews were the first to obtain the privilege of establishing banks in the Italian cities, and the first to discover the advantages of a system of checks and bills of exchange, of unique value in the development of modern commerce. Even in art, a sphere from which their rigorous laws might seem to have the effect of banishing them, they were not wholly inactive. They always numbered among themselves handicraftsmen. In Venice, in the sixteenth century, we find celebrated Jewish wood engravers. Jacob Weil's rules for slaughtering were published with vignettes by Hans Holbein, and one of Manasseh ben Israel's works was adorned with a frontispiece by Rembrandt. In our own generation Jews have won fame as painters and sculptors, while music has been their staunch companion, deserting them not even in the darkest days of the Ghetto. These certainly are abundant proofs that the Jew has a share in all the phases and stages of culture, from its first germs unto its latest complex development--a consoling, elevating reflection. A learned historian of literature, a Christian, in discussing this subject, was prompted to say: "Our first knowledge of philosophy, botany, astronomy, and cosmography, as well as the grammar of the holy language and the results of biblical study, we owe primarily to Jews." Another historian, also a Christian, closes a review of Jewish national traits with the words: "Looking back over the course of history, we find that in the gloom, bareness, and intellectual sloth of the middle ages, Jews maintained a rational system of agriculture, and built up international commerce, upon which rests the well-being of the nations."
