But the night's black was burst through by a blaze—
Thunder struck blow on blow, earth groaned and bore,
Through her whole length of mountain visible:
There lay the city thick and plain with spires,
And, like a ghost disshrouded, white the sea.
So may the truth be flashed out by one blow,
And Guido see, one instant, and be saved.
Else I avert my face, nor follow him
Into that sad obscure sequestered state
Where God unmakes but to remake the soul
