The night—its silence—its rest, was rent in twain by a savage, a sharp, a shrilly sound that ran from end to end of Thornfield Hall.
Chapter 20 · Narrator
Context
Jane describes the scream that has just shattered the silence of Thornfield, identifying it as something that moved through the entire building.
Analysis
The piling up of three sibilant adjectives—'savage,' 'sharp,' 'shrilly'—makes the sentence itself sound like a hiss, forcing the reader's mouth to mimic the violent sound being described. The personification of 'night' having 'silence' and 'rest' that can be 'rent in twain' frames the scream as an act of violence against peace itself, not just a loud noise.
Essay Tip
Support a thesis that Brontë uses sound as a form of violence in the novel—this quote shows how the scream doesn't just break silence but tears it apart, suggesting that what is hidden at Thornfield does damage even when unseen.
