And now the cause
Whereby athrough the throat of Aetna's Mount
Such vast tornado-fires out-breathe at times,
I will unfold: for with no middling might
Of devastation the flamy tempest rose
And held dominion in Sicilian fields:
Drawing upon itself the upturned faces
Of           clans, what time they saw afar
The skiey vaults a-fume and sparkling all,
And filled their bosoms with dread anxiety
Of what new thing nature were travailing at.
