The Pit and the Pendulum. Edgar Allan Poe (1809-1849). First published in 1842 in the literary annual The Gift: A Christmas and New Year’s Present for 1843.
The story is about the torments endured by a prisoner of the Spanish Inquisition, though Poe skews historical facts. The narrator of the story describes his experience of being tortured. The story is especially effective at inspiring fear in the reader because of its heavy focus on the senses, such as sound, emphasizing its reality, unlike many of Poe’s stories which are aided by the supernatural.
"And then there stole into my fancy, like a rich musical note, the thought of what sweet rest there must be in the grave." - from "The Pit and the Pendulum"
