The inside shutter of the iron grating, which the prisoner could open or shut at pleasure, was provided with a thin plate of horn, through which the daylight could scarcely penetrate. This shutter he usually allowed to remain open, unless the night was very cold, and the wind blew in that direction; for it had frequently happened to him, when it was closed, that he had started at midnight from a dreamy sleep, and fancied himself buried alive in the old chapel of his ancestors. But, now, life and every gleam of light and cheerfulness had become hateful to him; and, with a sort of spiteful pleasure, he had deprived himself of the scanty glimmer of daylight that still remained. "Come forth, my brother in misfortune, and teach me to look into the night of my futurity with thy glowing eyes," he muttered. "Let them call thee death's-bird, and corpse-bird, as they will: thou still seest clearly, when we and others are blind; and if thou shouldst now screech of death and misfortune, so much the better! that song now pleaseth me best." Whilst, with subdued voice, he thus gave expression to his gloomy thoughts, he opened the box, and took out the great night-bird, which perched itself familiarly upon his arm, and allowed itself to be caressed. The duke leant back on his pallet, and continued absorbed in moody reveries. The stillness of death reigned throughout the castle. By the faint light through the pane of horn, the prisoner was aware that the moon was shining. He at length closed his eyes, and fell into a slumber, without having first, as usual, shut up the owl. He wist not that he had been asleep, when the same fearful idea, that had before awoke him at midnight, again overwhelmed him: he fancied that he lay in his coffin, in the tomb of his fathers, and, in a kind of agony, half rose on his couch. He was not yet fully awake, when a frightful screech completely aroused him from his dream: he opened his eyes, and, in a ledge of the wall, near the mysterious inscriptions, he again saw the glowing eyes of the corpse-bird. It again screamed, and far more hideously than it was wont, at the same time staring at the dim light through the horn of the closed shutter. The duke looked in the same direction, and, to his astonishment, fancied he caught a glimpse of a face, half concealed in a hat, before the grating. A singular terror seized him, and he remained motionless, half erect, in bed. He now heard a gentle tap on the shutter, and sprang up. "Who is there?" he cried. "If you are human, speak!" The knocking at the shutter became a little louder, and a low, mysterious voice whispered--"Open, Duke Waldemar: a good friend would speak with you." "Is it possible?" he exclaimed: "a man? a good friend? Ha! be thou the Evil One himself, I fear not."
