Accordingly, on the 7th September, all the labourers of the country round were engaged, under the direction of the engineer Wilkin von Stedingen, in raising the walls and digging the trenches. The work was carried on with vigour by relays of peasants; nevertheless, the undertaking was on so great a scale, that several months must elapse before it could be completed.[211] [211] Kerssenbroeck, p. 75 _et seq._; Heresbach, p. 132. The cost of this terrible siege had already risen to 600,000 florins, the treasury was empty, and the country could bear no further taxes. Francis of Waldeck appealed to the Elector Palatine, the Electors of Cologne, Mainz, and Trèves, to give help and subsidies; he had recourse also to the princes and nobles of the Upper and Lower Rhine; and it was decided that a diet should assemble on the 13th December, 1534, to make arrangements for the complete subjugation of the insurgent fanatics. All the princes, Catholic and Protestant, trembled for their crowns, for the Anabaptist sect ramified throughout the country, and if John of Leyden were successful in Münster, they might expect similar risings in their own principalities.[212] [212] _Ibid._ p. 75; Bussierre, p. 372; Hast, p. 366. Whilst the preparations for the blockade were in progress, John Bockelson, inflated with pride, placed no bounds to his prodigality, his display, and his despotism. He frequently pronounced sentences of death. Thus Elizabeth Holschers was decapitated for having refused her husband what he demanded of her; Catherine of Osnabrück underwent the same sentence for having told one of the preachers that he was building his doctrines upon the sand; Catherine Knockenbecher lost her head for having taken two husbands. Polygamy was permitted, but polyandry was regarded as an unpardonable offence.[213] [213] Kerssenbroeck, p. 75; Bussierre, p. 372. However, the people chafed at the tyranny they were subjected to, and murmurs, low and threatening, continued to make themselves heard; whereupon, by King John's order, Dusentscheuer announced from the pulpit, "that all those who should for the future have doubts in the verities taught them, and who should venture to blame the king whom the Father had given them, would be given over to the anointed of the Lord to be extirpated out of Israel, decapitated by the headsman, and condemned to eternal oblivion." Amongst those who viewed with envy the rise and splendour of the tailor-king was Knipperdolling. He had opened his home to the prophet, had patronised him, introduced him to the people of Münster, and now the draper was eclipsed by the glory of the tailor. Thinking that the time was come for him to assume the pre-eminence, he made an attempt to dethrone Bockelson.
