Don A. How can I think you should speak truth to me
Who am a witness y' have been false to her,
To whom you now profess so high devotion?

Don O. I false to Porcia! take heed, Antonio,
So foul an injury provokes too much.
But, sir, I must confess I owe you more
Than the forgiveness of one gross mistake.

Don A. Rare impudence! I must not trust my senses.

Don O. If we cannot adjust this competition,
Let's charge our envious fortunes, not our passions,
With this fatal breach of friendship.

Don A. Leave your discourses, and defend yourself;
Either immediately renounce all claims
To Porcia, or this must speak the rest. [Shaking his sword.

Don O. Nay, then I must reply.

[They fight. A noise, as if the door were broken open.

Enter Don Henrique, Don Carlos, Leonido, and Geraldo, with their swords drawn.

Don H. What's this! Antonio fighting with Octavio?
This bravery is excessive, gallant friend,
Not to allow a share in your revenge
To him who's most concern'd: he must not fall
Without some marks of mine.

[Don Henrique makes at Don Octavio, and Don Antonio turns to Don Octavio's side.
