Among these effects must be included the buzzing in the head and singing in the ears, to which Luther’s letters allude for many a year. When, at the end of Jan., 1529, the violent “agonies and temptations” recurred, the buzzing in the ears again made itself felt. He writes: “For more than a week I have been ailing from dizziness and humming in the head (‘_vertigo et bombus_’), whether this be due to fatigue or to the malice of the devil I do not know. Pray for me that I may be strong in the faith.”[326] He also complains of this trouble in the head in the next letter, dating from early in Feb.[327] He was then unable to preach or to give lectures for nearly three weeks.[328] He goes on to say of himself: “In addition to the buffets of the angel of Satan [the temptations] I have also suffered from giddiness and headache.”[329] It was, however, as he himself points out, no real illness: “Almost constantly is it my fate to feel ill though my body is well.”[330] In the new kind of life he had to lead in the Castle of Coburg in 1530, when, to want of exercise, was added overwork and anxiety of mind, these neurasthenic phenomena again reappeared. He compares the noises in his head to thunder, or to a whirlwind. There was also present a tendency to fainting. At times he was unable even to look at any writing, or to bear the light owing to the weakness of his head.[331] Simultaneously the struggle with his thoughts gave him endless trouble; thus he writes: “It is the angel of Satan who buffets me so, but since I have endured death so often for Christ, I am quite ready for His sake to suffer this illness, or this Sabbath-peace of the head.”[332] “You declare,” he says laughingly in a letter to Melanchthon, “that I am pig-headed, but my pig-headedness is nothing compared with that of my head (‘_caput eigensinnigissimum_’); so powerfully does Satan compel me to make holiday and to waste my time.”[333] Towards the middle of August his head improved, but the tiresome buzzing frequently recurred. Luther complained later that, during this summer, he had been forced to waste half his time.[334] When, from this time onwards, “we hear him ever saying that he feels worn-out (‘_decrepitus_’), weary of life and desirous of death … all this is undoubtedly closely bound up with these nerve troubles.”[335] The morning hours became for him the worst, because during them he often suffered from dizziness. After his “_prandium_,” between nine and ten o’clock, he was wont to feel better. As a rule he slept well. The attacks which occurred early in 1532 must also be noted.
