   La ve¤  rite¤  , comme la lumie'  re, aveugle. Le mensonge, au contraire, est un beau cre¤  puscule qui met chaque objet en valeur. Truth, like light, blinds. A lie, on the contrary, is a beautiful twilight which shows the value of each object.

-Camus, Albert
  La Chute (translated by Stuart Gilbert).

O say, can you see, by the dawn's early light, What so proudly we hailed at the twilight's last gleamingö Whose broad stripes and bright stars, through the clouds of the fight, O'er the ramparts we watched were so gallantly streaming! Keynes And the rocket's red glare, the bombs bursting in air, Gave proof through thenight that our flag was still there; O! say, does that star-spangled banner yet wave O'er the land of the free, and the home of the brave?

An English homeögrey twilight poured On dewy pasture, dewy trees, Softer than sleepöall things in order stored, A haunt of ancient Peace.

-Tennyson
  Poems,'The Palace of Art', stanza 22, l.85^8.

Men, my brothers, men the workers, ever reaping something new: That which they have done but earnest of the things that they shall do: For I dipped into the future, far as human eye could see, Saw the vision of the world, and all the wonder that would be; Saw the heaven fill with commerce, argosies of magic sails, Pilots of the purple twilight, dropping down with costly bales; Heard the heavens fill with shouting, and there rained a ghastly dew From the nations'airy navies grappling in the central blue; Far along the world-wide whisper of the south-wind rushing warm, Ulysses With the standards of the peoples plunging through the thunder-storm; Till the war-drum throbbed no longer, and the battle- flags were furled In the Parliament of man, the Federation of the world.

-Tennyson
  Poems,'Locksley Hall', l.117^28.

Twilight and evening bell, And after that the dark! And may there be no sadness of farewell, When I embark; For though from out our bourne of Time and Place The flood may bear me far, I hope to see my Pilot face to face When I have crossed the bar.

-Tennyson
  'Crossing the Bar', l.9^16.This wasTennyson's last poem.

Out-worn heart, in a time out-worn, Come clear of the nets of wrong and right; Laugh, heart, again in the grey twilight, Sigh, heart, again in the dew of the morn.
