In fact, Miltitz brought letters addressed to the Elector and his counsellors, to the bishops and to the burgomaster of Wittemberg. He was also provided with seventy apostolic briefs. Should the flattery and the favours of Rome attain their object, and Frederick deliver Luther into her hands, these seventy briefs were to serve as a kind of passports. He was to produce and post up one of them in each of the towns through which he had to pass, and hoped he might thus succeed in dragging his prisoner, without opposition, all the way to Rome.[10] [10] Per singula oppida affigeret unum, et ita tutus me perduceret Romam. (L. Op. Lat. in Præf.) The pope seemed to have taken every precaution. The electoral court knew not well what course to take. Violence would have been resisted, but the difficulty was to oppose the chief of Christianity, when speaking with so much mildness, and apparently with so much reason. Would it not be the best plan, it was said, to place Luther somewhere in concealment until the storm was over?... An unexpected event relieved Luther, the Elector, and the Reformation, from this difficult situation. The aspect of affairs suddenly changed. [Sidenote: CIRCUMSTANCES FAVOURABLE TO THE REFORMATION.] On the 12th of January, 1519, Maximilian, the Emperor of Germany, died, and Frederick of Saxony, agreeably to the Germanic constitution, became regent of the empire. From this time the Elector feared not the schemes of nuncios, while new interests began to engross the court of Rome--interests which, obliging her to be chary of giving offence to Frederick, arrested the blow which Miltitz and De Vio were undoubtedly meditating. The pope earnestly desired to prevent Charles of Austria, already King of Naples, from ascending the imperial throne. A neighbouring king appeared to him more formidable than a German monk; and in his anxiety to secure the Elector, who might be of essential service to him in the matter, he resolved to give some respite to the monk that he might be the better able to oppose the king. Both, however, advanced in spite of him.
