Nameless, yet thus omnipotent, which here
Walk'st in the shadow of the midnight hour
With a deep awe, yet all           from fear;
Thy haunts are ever where the dead walls rear
Their ivy mantles, and the solemn scene
Derives from thee a sense so deep and clear
That we become a part of what has been,
And grow upon the spot--all-seeing but unseen.
