But if the charge of duplicity against Hus is founded mainly on ignorance of human nature, the accusation of violence which was brought against the Bohemian reformers may have been partially due to a confusion between two contests which were taking place at the same time, and in which the same parties were to some extent involved. For, while the Germans and Bohemians were struggling for supremacy in the University of Prague, Wenceslaus was devoting his energies to the punishment of the Archbishop and clergy for their championship of Gregory XII. In this, as in every other case, Wenceslaus soon damaged his cause by his utter want of self-restraint. Mobs were let loose upon the clergy, many acts of violence were committed, and a general sense of insecurity prevailed. Zbynĕk, who had plenty of that bull-dog courage which one might expect from an ex-soldier, replied to the king’s violence by putting Prague under an interdict. How the king might have met this defiance one may guess from his previous conduct; but the Archbishop and his clergy were saved from the fate of Nepomuc by a sudden change of circumstances. The Council of Pisa had agreed to depose the two existing claimants of the Papacy; and, after some discussion, they chose a new Pope, under the name of Alexander V. At first, of course, this Pope was not very favourably inclined to an Archbishop who had steadily opposed his election; but, when Zbynĕk accepted his authority, and showed his appreciation of him by sending him rich gifts, Alexander became alarmed at the spread of heresy in Bohemia, and granted a commission for inquiry into the writings of Wyclif, and a permission to Zbynĕk to remove those writings from the eyes of the faithful.
