Analysis of I Would I Were the Glow-Worm

I would I were the glow-worm, thou the flower,
That I might fill thy cup with glimmering light;
I would I were the bird, and thou the bower,
To sing thee songs throughout the summer night.

I would I were a pine tree deeply rooted,
And thou the lofty, cloud-beleaguered rock,
Still, while the blasts of heaven around us hooted,
To cleave to thee and weather every shock.

I would I were the rill, and thou the river;
So might I, leaping from some headlong steep,
With all my waters lost in thine for ever,
Be hurried onwards to the unfathomed deep.

I would--what would I not? O foolish dreaming!
My words are but as leaves by autumn shed,
That, in the faded moonlight idly gleaming,
Drop on the grave where all our love lies dead.
