Rousing myself, and half smiling at this temporary weakness, I resolved to brave it out in the true spirit of the hero of the enchanted house; so, taking lamp in hand, I sallied forth to make a tour of the palace. Notwithstanding every mental exertion the task was a severe one. I had to traverse waste halls and mysterious galleries, where the rays of the lamp extended but a short distance around me. I walked, as it were, in a mere halo of light, walled in by impenetrable darkness. The vaulted corridors were as caverns; the ceilings of the halls were lost in gloom. I recalled all that had been said of the danger from interlopers in these remote and ruined apartments. Might not some vagrant foe be lurking before or behind me, in the outer darkness? My own shadow, cast upon the wall, began to disturb me. The echoes of my own footsteps along the corridors made me pause and look round. I was traversing scenes fraught with dismal recollections. One dark passage led down to the mosque where Yusef, the Moorish monarch, the finisher of the Alhambra, had been basely murdered. In another place I trod the gallery where another monarch had been struck down by the poniard of a relative whom he had thwarted in his love. A low murmuring sound, as of stifled voices and clanking chains, now reached me. It seemed to come from the Hall of the Abencerrages. I knew it to be the rush of water through subterranean channels, but it sounded strangely in the night, and reminded me of the dismal stories to which it had given rise. Soon, however, my ear was assailed by sounds too fearfully real to be the work of fancy. As I was crossing the Hall of Ambassadors, low moans and broken ejaculations rose, as it were, from beneath my feet. I paused and listened. They then appeared to be outside of the tower--then again within. Then broke forth howlings as of an animal--then stifled shrieks and inarticulate ravings. Heard in that dead hour and singular place, the effect was thrilling. I had no desire for further perambulation; but returned to my chamber with infinitely more alacrity than I had sallied forth, and drew my breath more freely when once more within its walls and the door bolted behind me. When I awoke in the morning, with the sun shining in at my window and lighting up every part of the building with his cheerful and truth-telling beams, I could scarcely recall the shadows and fancies conjured up by the gloom of the preceding night; or believe that the scenes around me, so naked and apparent, could have been clothed with such imaginary horrors. Still, the dismal howlings and ejaculations I had heard were not ideal; they were soon accounted for, however, by my handmaid Dolores: being the ravings of a poor maniac, a brother of her aunt, who was subject to violent paroxysms, during which he was confined in a vaulted room beneath the Hall of Ambassadors.
