_Luther._--Luther[389] attributed his physical pains and his dreams to the arts of the devil, though all those of which he has left us a description are clearly due to nervous phenomena. He often suffered, _e.g._, from an anguish which nothing could lighten, caused, according to him, by the anger of an offended God. At 27, he began to be seized with attacks of giddiness, accompanied by headaches and noises in the ears, which returned at the ages of 32, 38, 40, and 52, especially when he was on a journey. At thirty-eight, moreover, he had a real hallucination, perhaps favoured by excessive solitude. “When, in 1521,” he writes, “I was in my Patmos, in a room which was entered by no one except two pages who brought me my food, I heard, one evening, after I was in bed, nuts moving inside a sack, and flying of themselves against the ceiling and all round my bed. Scarcely had I gone to sleep, when I heard a tremendous noise, as if many berries were being thrown over; I rose, and cried, ‘Who art thou?’ commended myself to Christ,” &c. In the church at Wittenberg, he had just begun explaining the Epistle to the Romans, and had reached the words, “The just shall live by faith,” when he felt these ideas penetrate his mind, and heard that sentence repeated aloud several times in his ear. In 1507, he heard the same words when on his journey to Rome, and again in a voice of thunder, as he was dragging himself up the steps of the Scala Santa. “Not seldom,” he confesses, “has it happened to me to awake about midnight, and dispute with Satan concerning the Mass,” and he details the many arguments adduced by the Devil. _Savonarola._--But the illustration in every respect most apposite (if it did not seem almost a national blasphemy to say so) is that offered us by Savonarola. Under the influence of a vision, he believed himself, even from his youth, sent by Christ to redeem the country from its corruption. One day, while speaking to a nun, it seemed to him that heaven suddenly opened; and he saw in a vision the calamities of the Church, and heard a voice commanding him to announce them to the people. The visions of the Apocalypse and of the Old Testament prophets passed in review before him. In 1491 he wished to leave off treating of politics in his sermons. “I watched all Saturday, and the whole night, but at daybreak, while I was praying, I heard a voice say, ‘Fool, dost thou not see that God will have thee go on in the same way?’” In 1492, while preaching during Advent, he had a vision of a sword, on which was written, “_Gladius Domini super terram_.” Suddenly, the sword turned towards the earth, the air was darkened, there was a rain of swords, arrows, and fire, and the earth became a prey to famine and pestilence. From this moment, he began to predict the pestilence which, in fact, afterwards came to pass.
