Count Thurn immediately summoned a convention of six delegates from each of the districts, called circles in Bohemia. The delegates met at Prague on the 16th of March, 1618. An immense concourse of Protestants from all parts of the surrounding country accompanied the delegates to the capital. Count Thurn was a man of surpassing eloquence, and seemed to control at will all the passions of the human heart. In the boldest strains of eloquence he addressed the assembly, and roused them to the most enthusiastic resolve to defend at all hazards their civil and religious rights. They unanimously passed a resolve that the demolition of the church and the suspension of the Protestant worship were violations of the royal edict, and they drew up a petition to the emperor demanding the redress of this grievance, and the liberation of the imprisoned deputies from Brunau. The meeting then adjourned, to be reassembled soon to hear the reply of the emperor.
As the delegates and the multitudes who accompanied them returned to their homes, they spread everywhere the impression produced upon their minds by the glowing eloquence of Count Thurn. The Protestant mind was roused to the highest pitch by the truthful representation, that the court had adopted a deliberate plan for the utter extirpation of Protestant worship throughout Bohemia, and that foreign troops were to be brought in to execute this decree. These convictions were strengthened and the alarm increased by the defiant reply which Matthias sent back from his palace in Vienna to his Bohemian subjects. He accused the delegates of treason and of circulating false and slanderous reports, and declared that they should be punished according to their deserts. He forbade them to meet again, or to interfere in any way with the affairs of Brunau, stating that at his leisure he would repair to Prague and attend to the business himself.
The king could not have framed an answer better calculated to exasperate the people, and rouse them to the most determined resistance. Count Thurn, regardless of the prohibition, called the delegates together and read to them the answer, which the king had not addressed to them but to the council of regency. He then addressed them again in those impassioned strains which he had ever at command, and roused them almost to fury against those Catholic lords who had dictated this answer to the king and obtained his signature.
