Classic Poem

I have heard whispers that I cannot speak,
Melodies, whose uncapturable tone
Drifted by starlight out of the unknown,
And left me shaken with beauty, and faint and weak.
And in the midnight when the timbers creak
Dreams have possessed me, greater than my own,
And in my solitary heart alone
I have seen grails I never will dare seek.

Why thunder the incalculable wings
About me so, if I am not to fly?
Why do the voices yet within me cry
Melodious? Why do the wild lights gleam,
And spill strange beauty over common things?
I am not visionary. Do I dream?
