This literary productivity was largely stimulated by the rapid growth of Jewish typography in Poland. The first Jewish book printed in that country is the Pentateuch (Cracow, 1530). In the second half of the sixteenth century two large printing-presses, those of Cracow and Lublin, were active in publishing a vast number of old and new books from the domain of Talmudic, Rabbinic, and popular-didactic literature. In 1566 King Sigismund Augustus granted Benedict Levita, of Cracow, the monopoly of importing into Poland Jewish books from abroad. Again, in 1578, Stephen Batory bestowed on a certain Kalman the right of printing Jewish books in Lublin, owing to the difficulty of importing them from abroad. One of the causes of this intensified typographic activity in Poland was the papal censorship of the Talmud, which was established in Italy in 1564. From that time the printing-offices of Cracow and Lublin competed successfully with the technically perfected printing-presses of Venice and Prague, and the Polish book-market, as a result, was more and more dominated by local editions. 4. SECULAR SCIENCES, PHILOSOPHY, CABALA, AND APOLOGETICS The Talmudic and Rabbinic science of law, absorbing as it did the best mental energies of Polish Jewry, left but little room for the other branches of literary endeavor. Among the daring "swimmers in the Talmudic ocean," contending for mastery in erudition and dialectic skill, there were but few with deeper spiritual longings who evinced an interest in questions of philosophy and natural science. The only exceptions were the physicians, who, on account of their profession, received a secular education at the universities of that period.
