Which, like bird with a ferret in her haunt,

She needs must seize as sole way of escape

Though there was tied and twittering a decoy

To seem as if it tempted,—just the plume

O' the popinjay, not a real respite there

From tooth and claw of something in the dark,—

Giuseppe Caponsacchi.

Now begins

The tenebrific passage of the tale:

How hold a light, display the cavern's gorge?
