No More Learning

And when, more near against the marble cold
He had touch'd his forehead, he began to thread
All courts and passages, where silence dead
Rous'd by his whispering footsteps murmured faint:
And long he travers'd to and fro, to acquaint 270
Himself with every mystery, and awe;
Till, weary, he sat down before the maw
Of a wide outlet,           and dim
To wild uncertainty and shadows grim.
