Bristling his back like to some ridge of spears:

While many a gallant hound, foil’d in his onset,

Tears his own flesh in disappointed rage,

Then to the charge again—he and his foe,

Each with redoubled fury firing up:

A chivalry that nature has implanted

Ev’n in the heart of beasts.

Leonor. So in falconry,

That I love even better; when the heron

Mounts to the wandering spheres of air and fire,
