Poland in 1558, and was first a teacher in the Calvinistic gymnasium at Pińczów and later principal of the Calvinistic school in Cracow, conducting a bookstore at the same time. Owing to his fame as a bookdealer, he won the honor of being designated by King Stephen Batory in 1578 as court bookdealer.[214] Estienne Le Riche, known also as Stephen Dives, of Lyons, seems to have succeeded Tenaud, and was an important intermediary in the book business between Poland and the West.[215] As a result of this active book trade in Poland in the sixteenth century, the writings of Luther and Calvin and of other reformers were speedily imported into Poland and received wide circulation. As early as 1520 Luther’s books were brought to Cracow, sold in the university buildings to the students, and were read and discussed by them with the tacit approval of the faculty until they were condemned by Pope Leo X.[216] In the spread of intelligence regarding the new religious movement the Polish magnates, favoring and supporting the Reformation, played also an active and important part. A number of them established printing presses of their own for the distinct purpose of religious propaganda. Thus, for instance, Michael Radziwill, the Black, an ardent supporter of Calvinism, founded a printing press at Brześć-Litewski, where Calvinistic literature was printed, and where in 1563 the Radziwill Bible was published. John Kiszka, starosta of Żmudź, established presses at Łosk and Nieśwież. These together with Raków and for a time with Pińczów were publication centres for Arian literature. At Nieśwież in 1572 Budny’s Arian Bible was published. The presses at Pińczów were maintained by the Oleśnickis. Moreover, we must not fail to bear in mind that one of the earliest, most prolific and most influential Polish Protestant publication centres was Königsberg in East Prussia, where Prince Albert had established one of the best and largest printing and publishing enterprises of the time for the dissemination of the Reformation doctrines both in his own duchy and throughout Poland.[217]
