Robert Southey - Sonnet 07

(to the rainbow)

Mild arch of promise! on the evening sky
Thou shinest fair with many a lovely ray
Each in the other melting. Much mine eye
Delights to linger on thee; for the day,
Changeful and many-weather'd, seem'd to smile
Flashing brief splendor thro' its clouds awhile,
That deepen'd dark anon and fell in rain:
But pleasant is it now to pause, and view
Thy various tints of frail and watery hue,
And think the storm shall not return again.
Such is the smile that Piety bestows
On the good man's pale cheek, when he in peace
Departing gently from a world of woes,
Anticipates the realm where sorrows cease.

Robert Southey
