A few weeks later Luther related, not without pride, how the students “in the Carnival days made the Pope figure in the show [the students being dressed up to play the part], seated on a car with great pomp; it was really too droll. At the stream in the market-place they allowed him to escape with his Cardinals, bishops and attendants; he was then chased through various parts of the city: everything was well and grandly planned; for the enemy of Christ is deserving of such mockery, since he himself mocks at the greatest Princes and even Christ Himself. The verses which describe the whole scene are now being printed.” This was how Luther wrote to Spalatin, who was then with the Elector at the Diet of Worms.[123] Evil things were in store for Luther at Worms. It seemed that his summons thither was unavoidable, since Pope Leo X, in the new Bull, “_Decet Romanum Pontificem_,” of January 3, 1521, had declared that Luther, owing to his persistent contumacy, had, _ipso facto_, incurred excommunication and become liable to the penalties already decreed by law against heretics. Certain historians have extolled the great calmness which Luther preserved even during the stormy days when the excommunication arrived; they will have it that his composure of mind never deserted him. He himself, however, speaks otherwise. According to his own statements contained in the letters which give so speaking a testimony to the state of his mind, he frequently did not know what he was doing, and blindly obeyed the impulse which drove him onward. Luther’s behaviour at that time was the very reverse of the clear-sighted, enlightened and self-controlled conduct of holy and virtuous Churchmen when in the midst of storm and stress. He himself confessed with regard to his polemics: “Yes, indeed, I feel that I am not master of myself (_compos mei non sum_). I am carried away and know not by what spirit. I wish evil to none, but I am not on my guard against Satan, and it is to this that the fury of my enemies is due.”[124] To explain this inward turmoil we must take into account, not only the excommunication, but also the unexampled overexertion which at that time taxed his mental and physical powers. He was necessarily in a state of the utmost nervous tension. “Works of the most varied kind,” he says, in the letter quoted, “carry my thoughts in all directions. I have to speak publicly no less than twice daily. The revision of the Commentary on the Psalms engages my attention. At the same time I am preparing sermons for the press, I am also writing against my enemies, opposing the Bull in Latin and in German and working at my defence. Besides this I write letters to my friends. I am also obliged to entertain my ordinary visitors at home.” At this time Luther not unfrequently kept three printing-presses at work at once.
