I have just spoken of that morbid condition of the auditory nerve which rendered all music intolerable to the sufferer, with the exception of certain effects of stringed instruments. It was, perhaps, the narrow limits to which he thus confined himself upon the guitar, which gave birth, in great measure, to the fantastic character of his performances. But the fervid _facility_ of his _impromptus_ could not be so accounted for. They must have been, and were, in the notes, as well as in the words of his wild fantasias (for he not unfrequently accompanied himself with rhymed verbal improvisations), the result of that intense mental collectedness and concentration to which I have previously alluded as observable only in particular moments of the highest artificial excitement. The words of one of these rhapsodies I have easily remembered. I was, perhaps, the more forcibly impressed with it, as he gave it, because, in the under or mystic current of its meaning, I fancied that I perceived, and for the first time, a full consciousness on the part of Usher of the tottering of his lofty reason upon her throne. The verses, which were entitled “The Haunted Palace,” ran very nearly, if not accurately, thus: I. In the greenest of our valleys, By good angels tenanted, Once a fair and stately palace— Radiant palace—reared its head. In the monarch Thought’s dominion— It stood there! Never seraph spread a pinion Over fabric half so fair. II. Banners yellow, glorious, golden, On its roof did float and flow; (This—all this—was in the olden Time long ago) And every gentle air that dallied, In that sweet day, Along the ramparts plumed and pallid, A winged odor went away. III. Wanderers in that happy valley Through two luminous windows saw Spirits moving musically To a lute’s well-tunéd law, Round about a throne, where sitting (Porphyrogene!) In state his glory well befitting, The ruler of the realm was seen. IV. And all with pearl and ruby glowing Was the fair palace door, Through which came flowing, flowing, flowing, And sparkling evermore, A troop of Echoes whose sweet duty Was but to sing, In voices of surpassing beauty, The wit and wisdom of their king. V. But evil things, in robes of sorrow, Assailed the monarch’s high estate; (Ah, let us mourn, for never morrow Shall dawn upon him, desolate!) And, round about his home, the glory That blushed and bloomed Is but a dim-remembered story Of the old time entombed.
