The centrality of Italy and its importance for the printing revolution cannot be exaggerated. Cities in Italy—especially Venice—rapidly became the most important centers of the new industry already in the late fifteenth century. As Brian Richardson opens his book on print in Renaissance Italy:
The introduction of the printing press to Italy in or shortly before 1465 had profound consequences for all users of the written word. Books now became available in much larger quantities than before, they cost much less, and texts could thus be disseminated more quickly and more widely. The sale of copies of a text could also be controlled, in principle, to the benefit of its author. Texts in printed books were presented differently in some respects from those in manuscripts, and new texts were produced with new sets of readers in mind.
This description is also an accurate assessment of the Hebrew printing enterprise. Italy was the central focus for Hebrew book production from the late fifteenth century through the middle of the sixteenth century and remained one of the most important centers of Jewish printing in the later sixteenth, the seventeenth, and the eighteenth centuries. During the incunabula period, of 139 certain Hebrew editions produced by 40 different presses, more than 60 percent of those presses were in Italy.
It is well known in all the lands of exile that the printing coming from Venice is the most correct and accurate of all printing done today anywhere on earth. Rabbi Abraham ibn Migas, sixteenth-century Jewish physician and scholar from Istanbul.
The quality, sophistication, and novelty of Venetian Hebrew printing considerably surpassed that of other centers, for example, the Ottoman Empire and Eastern Europe, a view widely held among early modern Jewish intellectuals and their readers.
Italy housed innovative printer-publishers like Gershom Soncino and Daniel Bomberg, who made major advances in the Hebrew book in both typography and format. Of course, Italy’s importance in printing in general in the fifteenth and sixteenth centuries plays a role as well: It is somewhat beside the point to ask whether Soncino and Bomberg were in Italy because Italy was an important center of book production or whether they made Italy an important center of book production.
Centers of particular industries tend to attract talent and in turn produce more. The printing industry in Italy demanded talent—skilled editors, typesetters, proofreaders, and printers—and capital to produce books; Italy both attracted talent and capital and produced more of it. Italy’s importance was magnified by its geographic centrality in the Jewish world.
The Jews of northern Italy traded with Jews throughout the early modern Jewish world, from Germany and Poland-Lithuania to the Ottoman Empire and North Africa, by way of ports in Venice and other cities and overland routes across the Alps. Books printed in Italy circulated to all these areas, and books printed in the farther reaches of Jewish settlement made their way to Italy.
Moreover, northern Italy drew in Jews from a wide variety of Jewish communities—from Iberia, southern France, southern Italy, former Byzantine lands, Germany, and the Middle East—who brought with them their medieval traditions and manuscripts, leading to rich possibilities for textual production and publication.
Italy continued to be an important print center into the later seventeenth and eighteenth centuries, although it was no longer dominant—the locus of Hebrew and Yiddish printing had shifted to Amsterdam and other areas in the Ashkenazi kulturbereich.
