A few amber clouds floated in the sky without a breath of air to move them. The horizon was of a fine golden tint, changing gradually into a pure apple-green, and from that into the deep blue of the mid-heaven. – Washington Irving, “The Legend of Sleepy Hollow”

Look out into the July night, and see the broad belt of silver flame which flashes up the half of heaven, fresh and delicate as the bonfires of the meadow-flies. Yet the powers of numbers cannot compute its enormous age,—lasting as space and time,—embosomed in time and space. – Ralph Waldo Emerson, “Progress of Culture”

It was very dark; but in the murky sky there were masses of cloud which shone with a lurid light, like monstrous heaps of copper that had been heated in a furnace, and were growing cold. – Charles Dickens, Martin Chuzzlewit, Chapter XLII
