Melanchthon felt himself helpless in presence of the “tumult,” declared that no one save Luther himself could quell the excitement, and eagerly pressed his return. The revolutionary movement was extending beyond Wittenberg, in other towns in Electoral Saxony such as Grimma and Altenberg. Duke George of Saxony, the strenuous defender of the old faith, had been watching the proceedings from the beginning. As early as Nov. 21st, 1521, he had written to John Duke of Saxony, the brother of the Elector, warning him that, against ecclesiastical usage, the Sacrament of the Supper was being dispensed in both kinds in Wittenberg; he had informed him (Dec. 26th) that priests were threatened while saying the Mass; he had brought the “tumultuous deeds” in Electoral Saxony before the _Reichsregiment_ in January, with the result that imperial mandates were sent to the Elector Frederick and to the Bishops of Meissen, Merseburg, and Naumburg, requiring them to take measures to end the disturbances. The Elector was seriously disquieted. His anxieties were increased by a letter from Duke George (Feb. 2nd, 1522), declaring that Carlstadt and Zwilling were the instigators of all the riotous proceedings. He had commissioned one of his councillors, Hugold of Einsiedel, to try to put matters right; but the result had been small. It was probably in these circumstances that he wrote his _Instruction_ to Oswald, a burgher of Eisenach, with the intention that the contents should be communicated to Luther in the Wartburg. The _Instruction_ may have been the reason why Luther suddenly left the asylum where he had remained since his appearance at Worms by the command and under the protection of his prince.(312) If this _Instruction_ did finally determine him, it was only one of many things urging Luther to leave his solitude. He cared little for the influence of the Zwickau Prophets,(313) estimating them at their true value, but the weakness of Melanchthon, the destructive and dangerous impetuosity of Carlstadt, the spread of the tumult beyond Wittenberg, the determination of Duke George to make use of these outbursts to destroy the whole movement for reformation, and the interference of the _Reichsregiment_ with its mandates, made him feel that the decisive moment had come when he must be again among his own people. He started on his lonely journey, most of it through an enemy’s country, going by Erfurt, Jena, Borna, and Leipzig. He was dressed as “Junker Georg,” with beard on his chin and sword by his side. At Erfurt he had a good-humoured discussion with a priest in the inn; and Kessler, the Swiss student, tells how he met a stranger sitting in the parlour of the “Bear” at Jena with his hand on the hilt of his sword, and reading a small Hebrew Psalter. He got to Wittenberg on Friday, March 7th; spent that afternoon and the next day in discussing the situation with his friends Amsdorf, Melanchthon, and Jerome Schurf.(314)
