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 …
This simple nine-line poem describes how the poet is filled with joy when he sees a rainbow, and how he hopes he will always keep that sense of enchantment with the natural world. The poem contains Wordsworth’s famous declaration, ‘The Child is father of the Man’, highlighting how important childhood experience was to the Romantics in helping to shape the human beings they became in adult life.
