Nature had indeed endowed Luther from his cradle with that rare talent of humour which, amidst the trials of life, easily proves more valuable than a gold mine to him who has it. During his secular studies at Erfurt he had been able to give full play to this tendency as some relief after the hardships of early days. His preference for Terence, Juvenal, Plautus and Horace amongst the classic poets leads us to infer that he did so; and still more does Mathesius’s description, who says that, at that time, he was a “brisk and jolly fellow.” Monastic life and, later, his professorship and the strange course on which he entered must for a while have placed a rein on his humour, but it broke out all the more strongly when be brought his marvellous powers of imagination and extraordinary readiness in the use of the German tongue to the literary task of bringing over the masses to his new ideas.

Anyone desirous of winning the hearts of the German masses has always had to temper earnestness with jest, for a sense of humour is part of the nation’s birthright. The fact that Luther touched this chord was far more efficacious in securing for him loud applause and a large following than all his rhetoric and theological arguments.

Humour in his Writings and at his Home

It was in his polemics that Luther first turned to account his gift of humour; his manner of doing so was anything but refined.

The first of his German controversial works against a literary opponent was his “Von dem Bapstum tzu Rome wider dem hochberumpten Romanisten tzu Leiptzk”[1247] (the Franciscan Alveld or Alfeld), dating from May and June, 1520. Here he starts with a comical description of the “brave heroes in the market place at Leipzig, so well armed as we have never seen the like before. Their helmets they wear on their feet, their swords on their heads, their shields and breastplates hang down their back, and their lances they grip by the blade.... If Leipzig can produce such giants then that land must indeed be fertile.” On the last page of the same writing he puts the concluding touch to his work by telling Alveld, the “rude miller’s beast,” that he does “not yet know how to bray his hee-haw, hee-haw”; were I, says Luther, “to permit all the wantonness of these thick-heads even the very washerwomen would end by writing against me.” “What really helps it if a poor frog [like this fellow] blows himself out? Even were he to swell himself out to bursting-point he would never equal an ox.”

In his first German booklet against Emser, viz. his “An den Bock zu Leyptzck” (1521),[1248] he plays on the motto of Emser’s coat-of-arms “Beware of the goat.” There was really no call for Emser to inscribe these words on his note-paper, for from his whole behaviour there was no doubt that he was indeed a goat, and also that he could “do no more than butt.” Luther’s reply to all his threats would be: “Dear donkey, don’t lick! But God save the poor nanny-goats, whose horns are wrapped in silk, from such a he-goat; as for me, so God wills, there is no fear. Have you never heard the fable of the ass who tried to roar as loud as the lion? I myself might have been afraid of you had I not known you were an ass,” etc.

It is certainly not easy to believe his assertion, that it was only against his will that he had recourse to all this derision which he heaped on his adversaries in religious matters of such vital importance. He has it that his words, “though maybe biting and sarcastic,” are really “spoken from a heart that is breaking with grief and has been obliged to turn what is serious into abuse.”[1249] As a matter of fact the temptation to use just such weapons was too great, and the prospect of success too alluring for us to place much reliance in such an assurance. His “grief” was of quite another kind.

At a later date his humour, or rather his caustic and satirical manner of treating his opponents, looked to him so characteristic of his way of writing, that as he said, it would be quite easy to tell at a glance which were the polemical tracts due to his pen, even though they did not bear his name. This was his opinion of his “satirical list” of the relics of the Cardinal of Mayence.[1250] Writing of this work to his friend Jonas he says: “Whoever reads it and has ever been familiar with my ideas and my pen will say: Here is Luther; the Cardinal too will say: This is the work of that scamp Luther!... But never mind; if they pipe then I insist on dancing, and, if I survive, I hope one day to tread a measure with the bride of Mayence [the Cardinal].” He had still “some sweet tit-bits” which he would like “to lay on her red and rosy lips.”[1251] This last quotation may serve as a specimen of the rough humour found in his controversial letters.

The reader already knows how the Papacy had to bear the brunt of such jests and of an irony which often descends to the depths of vulgarity. (Above, vol. iii., p. 232-235; vol. iv., pp. 295 f., 304 f, 318 ff.)

But it was not only in his polemics that his jests came in useful. The jovial tone which often characterises his domestic life, the humour that seasons his Table-talk (even though too often it oversteps the bounds of the permissible) and makes itself felt even in his business letters and intimate correspondence with friends, appears as Luther’s almost inseparable companion, with whose smile and whose caustic irony he cannot dispense.
