On one unfortunate evening, after Roderick informs the narrator that Lady Madeline has passed on. Eventually he feels certain about the house itself is evil as it was built and lived in by his forefathers, and because he believes there is "sentience all vegetable things" implying that the house consists of such sentient things that has a "terrible influence" on him and Madeline. All of which are meant to indicate Roderick's preoccupation with anything that might help him understand his worries. Although no torches line the walls, a ghastly light radiates from the scene. One of Usher's paintings depicts a long subterranean tunnel with a low ceiling and white walls.
