In E.A Poe's "The Fall of the House of Usher" there was a artist mentioned.
" For me at least - in the circumstances then surrounding me - there arose out of the pure abstractions which the hypochondriac contrived to throw upon his canvass, an intensity of intolerable awe, no shadow of which felt I ever yet in the contemplation of the certainly glowing yet too concrete reveries of Fuseli''

Henry Fuseli - Switzerland's romantic painter, who created unforgettably nightmarish paintings.

I think, it is very good to analyse what author is mentioning in the text, it is really helpful, when trying to emphasize what he was imagining, what feeling he tries to produce etc.
