The first martyrs, Henry Voes and John Esch of Brussels, said Erasmus, made many Lutherans by their death. Luther wrote a hymn on the subject and published an open letter to the Christians of the Netherlands. [Sidenote: 1524] Censorship of the press was established in Holland in vain, for everything goes to show that Lutheranism rapidly increased. Popular interest in the subject seemed to be great. Every allusion to ecclesiastical corruption in speeches or in plays was applauded. Thirty-eight laborers were arrested at Antwerp for assembling to read and discuss the gospel. [Sidenote: 1525] Iconoclastic outbreaks occurred in which crucifixes were desecrated. In the same year an Italian in Antwerp wrote that though few people were openly Lutheran many were secretly so, and that he had been assured by leading citizens that if the revolting peasants of Germany approached Antwerp, twenty thousand armed men would rise in the city to assist them. [Sidenote: July 31] When a Lutheran was drowned in the Scheldt, {243} the act precipitated a riot. In 1527 the English ambassador wrote Wolsey from the Netherlands that two persons out of three "kept Luther's opinions," and that while the English New Testament was being printed in that city, repeated attempts on his part to induce the magistrates to interfere came to nothing. Protestant works also continued to pour from the presses. The Bible was soon translated into Dutch, and in the course of eight years four editions of the whole Bible and twenty-five editions of the New Testament were called for, though the complete Scriptures had never been printed in Dutch before. [Sidenote: October 14, 1529] Alarmed by the spread of heresy, attributed to too great mildness, the government now issued an edict that inaugurated a reign of terror. Death was decreed not only for all heretics but for all who, not being theologians, discussed articles of faith, or who caricatured God, Mary, or the saints, and for all who failed to denounce heretics known to them. While the government momentarily flattered itself that heresy had been stamped out, at most it had been driven under ground. One of the effects of the persecution was to isolate the Netherlands from the Empire culturally and to some small extent commercially.
