First comes the legible signature “_Doctor Martinus_” in Luther’s handwriting; below this, also quite legible, stands “_Doctor Luther_,” possibly denoting his wife, as Thiele very reasonably conjectures; finally we have the questionable “_Doctor plenus_.” To read “Hans” instead of “_plenus_,” is, according to Denifle, “quite out of the question,” as I also found when I came to examine the facsimile published by G. Evers in 1883.[1040] On the other hand, to judge by the facsimile, it appeared to me that “_Johannes_” might possibly be the true reading, and the Latin form also seemed to agree with that of the previous signatures. When I was able to examine the original in Rome in May, 1907, I convinced myself that, as a matter of fact, the badly formed and intertwined characters could be read as “_Johannes_”; this reading was also confirmed by Alfredo Monaci, the palæologist.[1041] Hence the reading “_Doctor plenus_,” too confidently introduced by Evers and repeated by Enders, though with a query, in his edition of Luther’s letters, may safely be consigned to oblivion. Even had it been correct, it would merely have afforded a fresh example of Luther’s jokes at his own expense, and would not necessarily have proved that his mirth was due to spirituous influence. In one letter of Luther’s, which speaks of the time he passed in the Castle of Coburg, we hear more of the disagreeable than of the cheering effects of wine. “I have brought on headache by drinking old wine in the Coburg,” he complains to his friend Wenceslaus Link, “and this our Wittenberg beer has not yet cured. I work little and am forced to be idle against my will because my head must have a rest.”[1042] In the Electoral accounts 25 Eimer of wine are set down for the period of Luther’s stay at the Coburg;[1043] seeing that he and two companions spent only 173 days there, our Protestant friends have hastened to allege “the frequent visits he received” in the Coburg.[1044] It is true that he had a good many visitors during the latter part of his stay. However this may be, the illness showed itself as early as May, 1530. His own diagnosis here is no less unsatisfactory than the accounts concerning the other maladies from which he suffered. No doubt the malady was chiefly nervous.
