Forget the vows of love you made to me?

GUIDO

I take them back.

DUCHESS

Alas, you cannot, Guido,
For they are part of nature now; the air
Is tremulous with their music, and outside
The little birds sing sweeter for those vows.

GUIDO

There lies a barrier between us now,
Which then I knew not, or I had forgot.

DUCHESS

There is no barrier, Guido; why, I will go
In poor attire, and will follow you
Over the world.

GUIDO

[wildly]
The world's not wide enough
To hold us two! Farewell, farewell for ever.
