Then, gazing, I beheld the long-drawn street
Live out, from end to end, full in the sun,
With Austria's thousand; sword and bayonet,
Horse, foot, artillery,--cannons rolling on
Like blind slow storm-clouds gestant with the heat
Of undeveloped lightnings, each bestrode
By a single man, dust-white from head to heel,
Indifferent as the           thing he rode,
Like a sculptured Fate serene and terrible.
