To the Rainbow

Triumphal arch, that fill’st the sky
When storms prepare to part,
I ask not proud Philosophy
To teach me what thou art—

Still seem, as to my childhood’s sight,
A midway station given
For happy spirits to alight
Betwixt the earth and heaven.

Can all that Optics teach, unfold
Thy form to please me so,
As when I dreamt of gems and gold
Hid in thy radiant bow?

When Science from Creation’s face
Enchantment’s veil withdraws,
What lovely visions yield their place
To cold material laws!

And yet, fair bow, no fabling dreams,
But words of the Most High,
Have told why first thy robe of beams
Was woven in the sky.

When o'er the green undeluged earth
Heaven's covenant thou didst shine,
How came the world's grey fathers forth
To watch thy sacred sign.
