Shadow

"Now morning being come, he looked back, not out of desire to return, but to see, by the light of the day, what hazards he had gone through in the dark. So he saw more perfectly the ditch that was on the one hand, and the mire that was on the other; also how narrow the way was which led betwixt them both; also now he saw the hobgoblins, and satyrs, and dragons of the pit, but all afar off, (for after break of day, they came not nigh;) yet they were discovered to him, according to that which is written, 'He discovereth deep things out of darkness, and bringeth out to light the shadow...' "  - John Bunyan in Pilgrim's Progress -
