Considering the metadata mentions themes of madness and isolation, how do the opening paragraphs—particularly the narrator's solitary journey and the description of the house as having "vacant eye-like windows"—begin to establish these themes before any characters are even introduced?

From the book

sher? It was a mystery all insoluble; nor could I grapple with the shadowy fancies that crowded upon me as I pondered. I was forced to fall back upon the unsatisfactory conclusion, that while, beyond doubt, there are combinations of very simple natural objects which have the power of thus affecting us, still the analysis of this power lies among considerations beyond our depth. It was possible, I reflected, that a mere different arrangement of the particulars of the scene, of the details of the picture, would be sufficient to modify, or perhaps to annihilate its capacity for…

poetic, sentiment, with which the mind usually receives even the sternest natural images of the desolate or terrible. I looked upon the scene before me--upon the mere house, and the simple landscape features of the domain--upon the bleak walls--upon the vacant eye-like windows--upon a few rank sedges--and upon a few white trunks of decayed trees--with an utter depression of soul which I can compare to no earthly sensation more properly than to the after-dream of the reveller upon opium--the bitter lapse into everyday life--the hideous dropping off of the veil.

In this there was much that reminded me of the specious totality of old wood-work which has rotted for long years in some neglected…

this intolerable agitation of soul. I have, indeed, no abhorrence of danger, except in its absolute effect--in terror. In this unnerved--in this pitiable condition--I feel that the period will sooner or later arrive when I must abandon life and reason together, in some struggle with the grim phantasm, FEAR." I learned, moreover, at intervals, and through broken and equivocal hints, another singular feature of his mental condition. He was enchained by certain superstitious impressions in regard to the dwelling which he tenanted, and whence, for many years, he had never ventured…

the door of iron, made our way, with toil, into the scarcely less gloomy apartments of the upper portion of the house. And now, some days of bitter grief having elapsed, an observable change came over the features of the mental disorder of my friend. His ordinary manner had vanished. His ordinary occupations were neglected or forgotten. He roamed from chamber to chamber with hurried, unequal, and objectless step. The pallor of his countenance had assumed, if possible, a more ghastly hue--but the luminousness of his eye had utterly gone out. The once occasional huskiness of his tone…
