VIOLA

¹⁵I left no ring with her. What means this lady?

Fortune forbid my outside have not charmed her!

She made good view of me, indeed so much

That sure methought her eyes had lost her tongue,

For she did speak in starts distractedly.

²⁰She loves me, sure! The cunning of her passion

Invites me in this churlish messenger.

None of my lord’s ring? Why, he sent her none.

I am the man. If it be so, as ’tis,

Poor lady, she were better love a dream.

²⁵Disguise, I see thou art a wickedness,

Wherein the pregnant enemy does much.

How easy is it for the proper false

In women’s waxen hearts to set their forms!

Alas, our frailty is the cause, not we,

³⁰For such as we are made of, such we be.

How will this fadge? My master loves her dearly,

And I, poor monster, fond as much on him,

And she, mistaken, seems to dote on me.

What will become of this? As I am man,

³⁵My state is desperate for my master’s love.

As I am woman, now, alas the day,

What thriftless sighs shall poor Olivia breathe!

O time, thou must untangle this, not I.

It is too hard a knot for me to untie!

What is the ring to which Viola refers in the first line (marked line 15)?
