Poised between which alternately she burns

And freezes, while two falcons, wheeling round,

Strive to out-mount her, tilting all along

The fair blue field of heaven for their lists;

Until out-ris’n and stricken, drencht in blood,

Plumb down she falls like to some crimson star;

A rivalry that nature has implanted

Ev’n in the breast of birds.

Enter Pedro.
