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;
So be it when I shall grow old,
Or let me die!
The Child is father of the Man;
And I could wish my days to be
Bound each to each by natural piety.
"My Heart Leaps Up", also known as "The Rainbow", is a poem by the British Romantic poet William Wordsworth. Noted for its simple structure and language, it describes joy felt at viewing a rainbow.
