From depth to height, from height to loftier height,
The climber sets his foot and sets his face,
Tracks lingering sunbeams to their halting-place,
And counts the last pulsations of the light.
Strenuous thro' day and unsurprised by night
He runs a race with Time, and wins the race,
Emptied and stripped of all save only Grace,
Will, Love, - a threefold panoply of might.
Darkness descends for light he toiled to seek;
He stumbles on the darkened mountain-head,
Left breathless in the unbreathable thin air,
Made freeman of the living and the dead, -
He wots not he has topped the topmost peak,
But the returning sun will find him there.

(Christina Rossetti)
