The Twenty-First Canto is mostly another segment from Renaissance Italy, again with the obsession of accounting and financial relationships.

But then, he manages to insert something like this:

And the sea with tin flash in the sun-dazzle,
                                      Like dark wine in the shadows.
” Wind between the sea and the mountains”
  ‘The tree-spheres half dark against sea
                                      half clear against sunset,
The sun’s keel freighted with with cloud,
And after that hour, dry darkness
Floating flame in the air, gonade in organdy,
Dry flamelet, a petal borne in the wind.
Gigneti kalon.
Impentrable as the ignorance of old women.

Dazzling stuff. I notice that much of his most gorgeous writing is about the sea. Did he merely find it particularly inspiring or is there something more to it?
