OLIVIA

Now, sir, what is your text?

VIOLA

Most sweet lady—

OLIVIA

^₂₀₀A comfortable doctrine, and much may be said of it. Where lies your text?

VIOLA

In Orsino’s bosom.

OLIVIA

In his bosom? In what chapter of his bosom?

VIOLA

To answer by the method, in the first of his heart.

OLIVIA

²⁰⁵Oh, I have read it. It is heresy. Have you no more to say?

VIOLA

Good madam, let me see your face.

OLIVIA

Have you any commission from your lord to negotiate with my face? You are now out of your text. But we will draw the curtain and show you the picture. Look you, sir, such a one I was this present. Is ’t not well done?
