The Soul's Sphere

Come prisoned moon in steep cloud-fastnesses,--
Throned queen and thralled; some dying sun whose pyre
Blazed with momentous memorable fire;--
Who hath not yearned and fed his heart with these?
Who, sleepless, hath not anguished to appease
Tragical shadow's realm of sound and sight
Conjectured in the lamentable night?...
Lo! the soul's sphere of infinite images!

What sense shall count them? Whether it forecast
The rose-winged hours that flutter in the van
Of Love's unquestioning unreveale'd span,--
Visions of golden futures: or that last
Wild pageant of the accumulated past
That clangs and flashes for a drowning man.
