"'When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; What is man, that thou art mindful of him?'"
-Poul Anderson, The Boat Of A Million Years (London, 1991), XIX, pp. 599-600.
Having survived through history into an indefinite future, the immortals plan to meet again after a further million years! That must be the longest lifespan of any fictional characters although, of course, Anderson cannot show us those million years. (I have just remembered that some fantasy characters live even longer.)
One of Brian Aldiss' characters says:
"'With more time...well, all our values would change, wouldn't they?'"
-Brian Aldiss, "The Circulation Of The Blood..." IN Harry Harrison, Ed., Four For The Future (London, 1974), pp. 5-32 AT p. 32.
My point, exactly. The closing phrase of the concluding sentence informs us that this woman and her husband will live "...for the next score and a half of centuries." (ibid.)
That Biblical phraseology almost conceals the meaning: three thousand years. That suddenly does not seem so long any more. My next task is to reread the sequel, "...And The Stagnation Of The Heart." (pp. 33-44)
