Analysis of L'Avenir

I saw the human millions as the sand
Unruffled on the starlit wilderness.
The day was near, and every star grew less
In universal dawn. Then woke a band
Of wheeling winds, and made a mighty stress
Of morning weather; and still wilder went
O'er shifting plains, till, in their last excess,
A whirlwind whirled across the whirling land.
Heaven blackened over it; a voice of woes
Foreran it; the great noise of clanging foes
Hurtled behind; beneath the earth was rent,
And howling Death, like an uncaverned beast,
Leaped from his lair. Meanwhile morn oped the East,
And thro' the dusty tumult God arose.
