When, however, the Brothers arrived in Prague, they found that the Committee of the Masters of Arts intended to administer a rebuke, without hearing the defence of the accused parties. Against this injustice the Brothers protested; and at last the nobles and citizens succeeded in persuading the Masters to withdraw, before the accused persons were introduced. When, then, the Brothers appeared to answer the charges against them, they found themselves in the presence only of the nobles and citizens, who informed them that their mere appearance in Prague was all that was required of them, and that they might now go home again. This result was considered to be, in the main, a victory for the Brothers. But some of them were more indignant at the time which had been wasted than pleased at their escape from condemnation; and Lukas and his friends followed up this visit by an energetic war of pamphlets. A new weapon, it must be remembered, was now at the service of all promoters of new teaching. The invention of printing had quickly spread to Bohemia; and, in 1468, the fourth printing-press ever established in Europe had begun to work at Pilsen. The Brothers quickly saw the advantage of the new discovery; and, in 1500, they established a printing-press at Mláda Boleslav. More than one lady of rank joined the Brotherhood; and at least one Catholic noble found the new creed rapidly spreading among his dependants. Ladislaus now recognised the mistake which he had made in ignoring the constitutional methods of procedure. He therefore resolved to appeal to the regular Assemblies for support in his war against heresy; and he believed that he would find his best chance in Moravia. The Moravian Assembly, unlike the Bohemian, admitted the clergy to a special representation as a fourth estate; the Bishop of Olmütz had been active in the propaganda against the Brotherhood; and the great power which the Germans and Catholics had obtained in Moravia during the wars, seemed to point to an easy victory in the Moravian Assembly. But again the King had miscalculated. The victories of the Germans and Catholics had excited against them a bitterness, both national and religious, far more intense than was to be found in other parts of the kingdom. The cruelties of Sigismund, the Germanising zeal of Albert of Austria, and the many injustices of Sternberg and the Catholic League, had consolidated against them a mass of Moravian feeling, which, if unable to secure victories on the battlefield, was eminently calculated to give strength to an opposition in the Assembly. To the Bohemians of the western province the Catholics and Germans were enemies, whom they had met on equal terms and often thoroughly routed; to the Moravians they were victorious tyrants, whose rule was to be thrown off at the first opportunity.
