The roaring fountain, hurling an Atlantic
Of liquid ice that flashed with flame and foam?
An opal spirit, various and many formed,—
In whose clear heart reverberant fire stormed,—
Seemed its inhabitant; and through pale halls,
And deep diaphanous walls,
And corridors of whiteness,
Auroral colors swarmed,
As rosy-flickering stains,
Or lambent green, or gold, or crimson, warmed
