My heart leaps up when I behold A rainbow in the sky: So was it when my life began; So is it now I am a man … - William Wordsworth

If I should be, where I no more can hear Thy voice, nor catch from thy wild eyes these gleams Of past existence, wilt thou then forget That on the banks of this delightful stream We stood together; And that I, so long A worshipper of Nature, hither came, Unwearied in that service: rather say With warmer love, oh! with far deeper zeal Of holier love. Now wilt thou then forget, That after many wanderings, many years Of absence, these steep woods and lofty cliffs, And this green pastoral landscape, were to me More dear, both for themselves, and for thy sake.

Whither is fled the visionary gleam? Where is it now, the glory and the dream?

No bird, but an invisible thing, A voice, a mystery.
