How hard it is to hide the sparks of nature!

Belarius
How hard it is to hide the sparks of nature!
These boys know little they are sons to th’ King,
Nor Cymbeline dreams that they are alive.

The game is up!

They think they are mine, and, though trained up thus meanly,
I’ th’ cave wherein they bow, their thoughts do hit
The roofs of palaces, and nature prompts them
In simple and low things to prince it much
Beyond the trick of others. This Polydor,
The heir of Cymbeline and Britain, who
The King his father called Guiderius—Jove!
When on my three-foot stool I sit and tell
The warlike feats I have done, his spirits fly out
Into my story; say “Thus mine enemy fell,
And thus I set my foot on ’s neck,” even then
The princely blood flows in his cheek, he sweats,
Strains his young nerves, and puts himself in posture
That acts my words. The younger brother, Cadwal,
Once Arviragus, in as like a figure
Strikes life into my speech and shows much more
His own conceiving. Hark, the game is roused!
O Cymbeline, heaven and my conscience knows
Thou didst unjustly banish me; whereon,
At three and two years old I stole these babes,
Thinking to bar thee of succession as
Thou refts me of my lands. Euriphile,
Thou wast their nurse; they took thee for their mother,
And every day do honor to her grave.
Myself, Belarius, that am Morgan called,
They take for natural father. The game is up!
