For this purpose he proceeded first to simulate a friendship for Wolkenlicht, the manifestations of which he gradually increased, until, after a day or two, he asked him to drink wine with him in the evening. Karl readily agreed. The painter produced some of his best; but took care not to allow Lilith to taste it; for he had cunningly prepared and mingled with it a decoction of certain herbs and other ingredients, exercising specific actions upon the brain, and tending to the inordinate excitement of those portions of it which are principally under the rule of the imagination. By the reaction of the brain during the operation of these stimulants, the imagination is filled with suggestions and images. The nature of these is determined by the prevailing mood of the time. They are such as the imagination would produce of itself, but increased in number and intensity. Teufelsbürst, without philosophising about it, called his preparation simply a love-philtre, a concoction well known by name, but the composition of which was the secret of only a few. Wolkenlicht had, of course, not the least suspicion of the treatment to which he was subjected. Teufelsbürst was, however, doomed to fresh disappointment. Not that his potion failed in the anticipated effect, for now Karl’s real sufferings began; but that such was the strength of Karl’s will, and his fear of doing anything that might give a pretext for banishing him from the presence of Lilith, that he was able to conceal his feelings far too successfully for the satisfaction of Teufelsbürst’s art. Yet he had to fetter himself with all the restraints that self-exhortation could load him with, to refrain from falling at the feet of Lilith and kissing the hem of her garment. For that, as the lowliest part of all that surrounded her, itself kissing the earth, seemed to come nearest within the reach of his ambition, and therefore to draw him the most. No doubt the painter had experience and penetration enough to perceive that he was suffering intensely; but he wanted to see the suffering embodied in outward signs, bringing it within the region over which his pencil held sway. He kept on, therefore, trying one thing after another, and rousing the poor youth to agony; till to his other sufferings were added, at length, those of failing health; a fact which notified itself evidently enough even for Teufelsbürst, though its signs were not of the sort he chiefly desired. But Karl endured all bravely. Meantime, for various reasons, he scarcely ever left the house. I must now interrupt the course of my story to introduce another element.
