Silver Tower in Frankfurt am Main; 2013-12-03.
Keen, poignant agonies seemed to shoot from his neck downward through every fiber of his body and limbs. These pains appeared to flash along well defined lines of ramification and to beat with an inconceivably rapid periodicity. They seemed like streams of pulsating fire heating him to an intolerable temperature. As to his head, he was conscious of nothing but a feeling of fullness—of congestion. These sensations were unaccompanied by thought. The intellectual part of his nature was already effaced; he had power only to feel, and feeling was torment. He was conscious of motion. Encompassed in a luminous cloud, of which he was now merely the fiery heart, without material substance, he swung through unthinkable arcs of oscillation, like a vast pendulum. Then all at once, with terrible suddenness, the light about him shot upward with the noise of a loud splash; a frightful roaring was in his ears, and all was cold and dark. He opened his eyes in the darkness and saw above him a gleam of light, but how distant, how inaccessible! He was still sinking, for the light became fainter and fainter until it was a mere glimmer. Then it began to grow and brighten, and he knew that he was rising toward the surface—knew it with reluctance, for he was now very comfortable.
