A Quick Word... From Achilles Tatius

"All diseases and wounds are usually more severe at night; they attack us more at our rest and increase our pain. When the body is relaxed, then a wound is free to fester. And when the body is inactive, wounds of the soul are all the more painful. During the day the eyes and ears are absorbed in many activities and help take the edge off illness by giving the soul no leisure in which to suffer. But once the body is constrained in quietude, the soul is set adrift in a sea of troubles. For then begins to stir all that until then slept: woes of the sorrowing, worries of the careworn, imperiled men's fears, the fires of men in love."
