It is quite possible that Aschenbach, in his half-distracted, half-inquisitive examination of the stranger, had been somewhat inconsiderate, for he suddenly became aware that his look was being answered, and indeed so militantly, so straight in the eye, so plainly with the intention of driving the thing through to the very end and compelling him to capitulate, that he turned away uncomfortably and began walking along by the fences, deciding casually that he would pay no further attention to the man. The next minute he had forgotten him. But perhaps the exotic element in the stranger's appearance had worked on his imagination; or a new physical or spiritual influence of some sort had come into play. He was quite astonished to note a peculiar inner expansion, a kind of roving unrest, a youthful longing after far-off places: a feeling so vivid, so new, or so long dormant and neglected, that, with his hands behind his back and his eyes on the ground, he came to a sudden stop, and examined into the nature and purport of this emotion. It was the desire for travel, nothing more; although, to be sure, it had attacked him violently, and was heightened to a passion, even to the point of an hallucination. His yearnings crystallized; his imagination, still in ferment from his hours of work, actually pictured all the marvels and terrors of a manifold world which it was suddenly struggling to conceive. He saw a landscape, a tropical swampland under a heavy, murky sky, damp, luxuriant, and enormous, a kind of prehistoric wilderness of islands, bogs, and arms of water, sluggish with mud; he saw, near him and in the distance, the hairy shafts of palms rising out of a rank lecherous thicket, out of places where the plant-life was fat, swollen, and blossoming exorbitantly; he saw strangely misshapen trees sending their roots into the ground, into stagnant pools with greenish reflections; and here, between floating flowers which were milk-white and large as dishes, birds of a strange nature, high-shouldered, with crooked bills, were standing in the muck, and looking motionlessly to one side; between dense, knotted stalks of bamboo he saw the glint from the eyes of a crouching tiger--and he felt his heart knocking with fear and with puzzling desires. Then the image disappeared; and with a shake of his head Aschenbach resumed his walk along past the fences of the stone-masons' establishments.
