For such disguise as haply shall become
The form of my intent. I'll serve this Duke:
Thou shalt present me as an eunuch to him:
It may be worth thy pains; for I can sing,
And speak to him in many sorts of music,
That will allow me very worth his service.
What else may hap to time I will commit;
Only shape thou thy silence to my wit.
Cap. Be you his eunuch, and your mute I'll be:
When my tongue blabs, then let mine eyes not see.
