The Rainbow by William Wordsworth.March 26, 1802.

My heart leaps up when i behold

A rainbow in the sky:

So it was it when my life began;

So is it now i am a man;

So be it when I shall grow old, Or let me die!

The Child is the father of the Man;

And i could wish my days to be 

Bound each to each by natural piety.
