The riv'n rapt brain: as when in some large lake
From pressure of descendant crags, which lapse
Disjointed, crumbling from their parent slope
At slender interval, the level calm
Is ridg'd with restless and increasing spheres
Which break upon each other, each th' effect
Of separate impulse, but more fleet and strong
Than its precursor, till the eyes in vain
Amid the wild unrest of swimming shade
Dappled with hollow and alternate rise
Of interpenetrated arc, would scan
Definite round.
I know not if I shape
These things with accurate similitude
From visible objects, for but dimly now,
Less vivid than a half-forgotten dream,
The memory of that mental excellence
Comes o'er me, and it may be I entwine
The indecision of my present mind
With its past clearness, yet it seems to me
As even then the torrent of quick thought
Absorbed me from the nature of itself
With its own fleetness. Where is he that, borne
Adown the sloping of an arrowy stream,
Could link his shallop to the fleeting edge,
And muse midway with philosophic calm
Upon the wondrous laws which regulate
The fierceness of the bounding element?
My thoughts which long had grovell'd in the slime
Of this dull world, like dusky worms which house
