This declaration satisfied his friends, though it did not satisfy the members of the diet. Luther was permitted to retire. He had gained the confidence of the nation. From that time, he was its idol, and the acknowledged leader of the greatest insurrection of human intelligence which modern times have seen. The great principles of the reformation were declared. The great hero of the Reformation had planted his cause upon a rock. And yet his labors had but just commenced. Henceforth, his life was toil and vexation. New difficulties continually arose. New questions had to be continually settled. Luther, by his letters, was every where. He commenced the translation of the Scriptures; he wrote endless controversial tracts; his correspondence was unparalleled; his efforts as a preacher were prodigious. But he was equal to it all; was wonderfully adapted to his age and circumstances. [Sidenote: Imprisonment at Wartburg.] About this time commenced his voluntary imprisonment at Wartburg, among the Thuringian forests: he being probably conducted thither by the orders of the elector of Saxony. Here he was out of sight, but not out of mind; and his retirement, under the disguise of a knight, gave him leisure for literary labor. In the old Castle of Wartburg, a great part of the Scriptures was translated into that beautiful and simple version, which is still the standard of the German language. [Sidenote: Carlstadt.] While Luther was translating the Scriptures, in his retreat, Wittemberg was the scene of new commotions, pregnant with great results.

Such a party ever exists in all reforms; for there are some persons who are always inclined to ultra and extravagant courses. Carlstadt was a type of such men. He was learned, sincere, and amiable, but did not know where to stop; and the experiment was now to be tried, whether it was possible to introduce a necessary reform, without annihilating also all the results of the labors of preceding generations. Carlstadt's mind was not well balanced, and to him the reformation was only a half measure, and a useless movement, unless all the external observances of religion and the whole economy of the church were destroyed. He abolished, or desired to abolish, all priestly garments, all fasts and holydays, all pictures in the churches, and all emblematical ceremonies of every kind. He insisted upon closing all places of public amusement, the abolition of all religious communities, and the division of their possessions among the poor. He maintained that there was no need of learning, or of academic studies, and even went into the houses of the peasantry to seek explanation of difficult passages of Scripture. For such innovations, the age was certainly not
