This is Rupert Brooke's 'The Charm'. You can decide for yourself whether this, or this, or this, represents the best of his 'sleeping lover' poems...
In darkness the loud sea makes moan;
And earth is shaken, and all evils creep
About her ways. Oh, now to know you sleep!
Out of the whirling blinding moil, alone,
Out of the slow grim fight,
One thought to wing -- to you, asleep,
In some cool room that's open to the night
Lying half-forward, breathing quietly,
One white hand on the white
Unrumpled sheet, and the ever-moving hair
Quiet and still at length!...
Your magic and your beauty and your strength,
Like hills at noon or sunlight on a tree,
Sleeping prevail in earth and air.
In the sweet gloom above the brown and white
Night benedictions hover; and the winds of night
Move gently round the room, and watch you there.
And through the dreadful hours
The trees and waters and the hills have kept
The sacred vigil while you slept,
And lay a way of dew and flowers
Where your feet, your morning feet, shall tread.
And still the darkness ebbs about your bed.
Quiet, and strange, and loving-kind, you sleep.
And holy joy about the earth is shed;
And holiness upon the deep.
