Little-Ease
From The Fall : To be sure, you are not familiar with that dungeon cell that was called the little-ease in the Middle Ages. In general, one was forgotten there for life. That cell was distinguished from others by ingenious dimensions. It was not high enough to stand up in nor yet wide enough to lie down in. One had to take on an awkward manner and live on the diagonal; sleep was a collapse, and waking a squatting. * I believe this little-ease is in the Tower of London: [From Wikimedia Commons]
