Viola: Conceal me what I am, and be my aid
For such disguise as haply shall become
The form of my intent. I'll serve this duke:
Thou shall 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.
[William Shakespeare, Twelfth Night, Act I - Scene II. The sea-coast.]
