Put out the light, and then put out the light. If I quench thee, thou flaming minister, I can again thy former light restore Should I repent me; but once put out thy light, Thou cunning'st pattern of excelling nature, I know not where is that Promethean heat That can thy light relume.
William Shakespeare (1564–1616), British dramatist, poet. Othello, in Othello, act 5, sc. 2, l. 7-13.
The "light" is both that of the candle ("flaming minister") he carries and that of Desdemona; Prometheus in Greek legend stole fire from the gods to give it to human beings; "relume" means light again.
