With pasture slopes, and flocks just visible; Then, further still, soft wavy wastes of forest, In all the varied tints of sylvan verdure, Descending to the plain; then, wide and boundless, The plain itself, with towns and cultured tracts, And its fair river gleaming in the light, With all its sweepy windings, seen and lost, And seen again, till through the pale grey tint Of distant space, it seem'd a loosen'd cestus From virgin's tunic blown; and still beyond, The earth's extended vastness from the sight Wore like the boundless ocean.
