He who, grown aged in this world of woe,
In deeds, not years, piercing the depths of life,
So that no wonder waits him; nor below
Can love or sorrow, fame, ambition, strife,
Cut to his heart again with the keen knife
Of silent, sharp endurance: he can tell
Why thought seeks refuge in lone caves, yet rife
With airy images, and shapes which dwell
Still unimpaired, though old, in the soul's haunted cell.
