William Allingham - After Sunset

The vast and solemn company of clouds
Around the Sun's death, lit, incarnadined,
Cool into ashy wan; as Night enshrouds
The level pasture, creeping up behind
Through voiceless vales, o'er lawn and purpled hill
And hazéd mead, her mystery to fulfil.
Cows low from far-off farms; the loitering wind
Sighs in the hedge, you hear it if you will,--
Tho' all the wood, alive atop with wings
Lifting and sinking through the leafy nooks,
Seethes with the clamour of a thousand rooks.
Now every sound at length is hush'd away.
These few are sacred moments. One more Day
Drops in the shadowy gulf of bygone things.

William Allingham
