Clive Staples Lewis - Irish Nocturne

Now the grey mist comes creeping up
From the waste ocean’s weedy strand
And fills the valley, as a cup
If filled of evil drink in a wizard’s hand;
And the trees fade out of sight,
Like dreary ghosts unhealthily,
Into the damp, pale night,
Till you almost think that a clearer eye could see
Some shape come up of a demon seeking apart
His meat, as Grendel sought in Harte
The thanes that sat by the wintry log—
Grendel or the shadowy mass
Of Balor, or the man with the face of clay,
The grey, grey walker who used to pass
Over the rock-arch nightly to his prey.
But here at the dumb, slow stream where the willows hang,
With never a wind to blow the mists apart,
Bitter and bitter it is for thee. O my heart,
Looking upon this land, where poets sang,
Thus with the dreary shroud
Unwholesome, over it spread,
And knowing the fog and the cloud
In her people’s heart and head
Even as it lies for ever upon her coasts
Making them dim and dreamy lest her sons should ever arise
And remember all their boasts;
For I know that the colourless skies
And the blurred horizons breed
Lonely desire and many words and brooding and never a deed.
