(Till giddy rapture almost doubt

I fly) through circling sciences,

Philosophies and histories!

Should the whirl slacken there, then verse,

Fining to music, shall asperse

Fresh and fresh fire-dew, till I strain

Intoxicate, half-break my chain!

Not joyless, though more favored feet

Stand calm, where I want wings to beat

The floor. At least earth's bond is broke!"
