Sometimes a single phrase in a single text raises a question that generates references to an unmanageable number of other texts.
How will the end of the world be announced - or presaged? Is "the world" Earth or the universe? Do we mean the end of everything or only of the present world order? Will the end, in whichever sense, arrive unannounced?
In Paris, on the Left Bank overlooking the Boulevard St. Germain, in 1902:
"Everard tried not to remember that in a dozen years this world would crash to ruin."
-Poul Anderson, The Shield Of Time (New York, 1991), PART ONE, 1902 A. D., p. 119.
The precursors of the Jehovah's Witnesses had predicted the end of the world - or at least the end of the present sinful world order - in 1914 and subsequently, of necessity, reinterpreted it. Thus, a supernatural event occurred then but the end will come soon.
In Anderson's After Doomsday, spaceships re-enter the Solar System after Earth has been sterilized. Its inhabitants would have had no warning. In his Tau Zero, the crew of a relativistic spaceship sees the universe fading and contracting. However, the sterilized Earth will be re-seeded and the contracted universe re-expands so is there an end? In Anderson's Harvest Of Stars and Genesis, the latter a highly appropriate title, consciousness and intelligence might survive the heat death of the universe.
(A British TV program is just now showing the East window in York Minster which begins with (the Biblical) Genesis and ends with Apocalypse.)
Before the Ragnarok, three cocks crow, in Jotunheim, Hel and Asgard, respectively. See
Cockcrow,
Addendum.
I could also reference James Blish, Isaac Asimov, Alan Moore and Neil Gaiman but perhaps Anderson alone, plus Voluspa and Apocalypse, is comprehensive enough?
This post was initiated by a passage in which James Bond reflects that Goldfinger, funding SMERSH, is:
"...piling up the surplus for the day when the trumpets would sound in the Kremlin and every golden sinew would be mobilized."
-Ian Fleming, Goldfinger (London, 1959), CHAPTER 7, p. 64.
So the free world would have ended when, metaphorically of course, trumpets sounded in the Kremlin? Unlikely and, in any case, did not happen.
