Sonnet: O my companion, O my sister Sleep

O my companion, O my sister Sleep,
The valley is all before us, bear me on.
High through the heaven of evening, hardly gone,
Beyond the harbour lights, beyond the steep,
Beyond the land and its lost benison
To where, majestic on the darkening deep,
The night comes forward from Mount Aurion.
O my companion, O my sister Sleep.

Above the surf-line, into the night-breeze;
Eastward above the ever-whispering seas;
Through the warm airs with no more watch to keep.
My day’s run out and all its dooms are graven.
O dear forerunner of Death and promise of Haven.
O my companion, O my sister Sleep.
