The proscribed, in the guise of Marranos, and under the hospitable shelter of their new homes, could not be banished from literary Spain, even in its newest departures. Indeed, for a long time Spanish and Italian literatures were brought into contact with each other only through the instrumentality of Jews. Not quite half a century after the expulsion of Jews from Portugal and their settlement in Italy, a Jew, Solomon Usque, made a Spanish translation of Petrarch (1567), dedicated to Alessandro Farnese, duke of Parma, and wrote Italian odes, dedicated to Cardinal Borromeo. At the zenith of the Renaissance, Jews won renown as Italian poets, and did valiant work as translators from Latin into Hebrew and Italian. In the later days of the movement, in the Reformation period, illustrious Christian scholars studied Hebrew under Jewish tutorship, and gave it a place on the curriculum of the universities. Luther himself submitted to rabbinical guidance in his biblical studies. In great numbers the Spanish exiles turned to Turkey, where numerous new communities rapidly arose. There, too, in Constantinople and elsewhere, Jews, like Elias Mizrachi and Elias Kapsali, were the first to pursue scientific research. We have now reached the days of deepest misery for Judaism. Yet, in the face of unrelenting oppression, Jews win places of esteem as diplomats, custodians and advocates of important interests at royal courts. From the earliest period of their history, Jews manifested special talent for the arts of diplomacy. In the Arabic-Spanish period they exercised great political influence upon Mohammedan caliphs. The Fatimide and Omayyad dynasties employed Jewish representatives and ministers, Samuel ibn Nagdela, for instance, being grand vizir of the caliph of Granada. Christian sovereigns also valued their services: as is well known, Charlemagne sent a Jewish ambassador to Haroun al Rashid; Pope Alexander III. appointed Yechiel ben Abraham as minister of finance; and so late as in the fifteenth century the wise statesman Isaac Abrabanel was minister to Alfonso V., of Portugal, and, wonderful to relate, for eight years to Ferdinand and Isabella, of Spain. At this time Jewish literature was blessed with a patron in the person of Joseph Nasi, duke of Naxos, whom, it is said, Sultan Selim II. wished to crown king of Cyprus. His rival was Solomon Ashkenazi, Turkish ambassador to the Venetian republic, who exercised decisive influence upon the election of a Polish king. And this is not the end of the roll of Jewish diplomats and ministers.
