Nathaniel Hawthorne,
Doctor Grimshawe's Secret: A romance…
(1882)
“ There is no window; but it seems to come through a stone, or something like it,--a dull gray medium, that makes noonday look like evening twilight. Though sometimes there is an effect as if something were striving to melt itself through this dull medium, and--never making a shadow--yet to produce the effect of a cloud gathering thickly over the sun. ”
