It was a great room, filled with the appliances and results of art. Many pictures, festooned with cobwebs, were hung carelessly on the dirty walls. Others, half finished, leaned against them, on the floor. Several, in different stages of progress, stood upon easels. But all spoke the cruel bent of the artist's genius. In one corner a lay figure was extended on a couch, covered with a pall of black velvet. Through its folds, the form beneath was easily discernible; and one hand and forearm protruded from beneath it, at right angles to the rest of the frame. Lottchen could not help shuddering when he saw it. Although he overcame the feeling in a moment, he felt a great repugnance to seating himself with his back towards it, as the arrangement of an easel, at which Teufelsbürst wished him to draw, rendered necessary. He contrived to edge himself round, so that when he lifted his eyes he should see the figure, and be sure that it could not rise without his being aware of it. But his master saw and understood his altered position; and under some pretence about the light, compelled him to resume the position in which he had placed him at first; after which he sat watching, over the top of his picture, the expression of his countenance as he tried to draw; reading in it the horrid fancy that the figure under the pall had risen, and was stealthily approaching to look over his shoulder. But Lottchen resisted the feeling, and, being already no contemptible draughtsman, was soon interested enough to forget it. And then, any moment _she_ might enter.
Now began a system of slow torture, for the chance of which the painter had been long on the watch--especially since he had first seen Karl lingering about the house. His opportunities of seeing physical suffering were nearly enough even for the diseased necessities of his art; but now he had one in his power, on whom, his own will fettering him, he could try any experiments he pleased for the production of a kind of suffering, in the observation of which he did not consider that he had yet sufficient experience. He would hold the very heart of the youth in his hand, and wring it and torture it to his own content. And lest Karl should be strong enough to prevent those expressions of pain for which he lay on the watch, he would make use of further means, known to himself, and known to few besides.
