Classic Poem

I saw my dream beyond a mountain height;
it was a stretch of pallid light, with trees
of such a green, as ne'er before the sight, nor after, sees.

First the resounding shower, with veiling screen
of clouds of deepest black, obscured the air:
and then the sun bared all things, to be seen equally fair.

And yet that dream of mine, by morning light,
shone to me in a flash, then was not seen,
so that the sky was no more dark, nor quite wholly serene.
