The university of Cracow had been reinstituted under Jagello in A.D. 1400, and organized after the model of that of Prague. Although the most flourishing period of this institution was the sixteenth century, yet it presented during the fifteenth to the Polish nobility a good opportunity of studying the classics; and it is doubtless through this preparatory familiarity with the ancient writers, that the phenomenon to which we have alluded must be principally accounted for. It was moreover now the epoch, when the genius of Christian Europe made the most decided efforts to shake off the chains which had fettered the freedom of thought. The doctrines of the German Reformers, although the number of their professed disciples was in proportion smaller than in Bohemia, had nevertheless a decided influence upon the general direction of the public mind. The wild flame of false religious zeal, which in Poland also under the sons and immediate successors of Jagello, had kindled the faggots in which the disciples of the new doctrines were called to seal the truth of their conviction with their blood, was extinguished before the milder wisdom of Sigismund I; although the early part of his reign was not free from religious persecution. The activity of the inquisition was restrained. But the new doctrines found a more decided support in Sigismund Augustus. Poland became, under his administration, the seat of a toleration then unequalled in the world. Communities of the most different religious principles formed themselves, at first under the indulgence of the king and the government, and finally under the protection of the law. Even the boldest theological skeptics of the age, the two Socini, found in Poland an asylum.[17]
