Caesar’s sister is called Octavia

Enobarbus
Caesar's sister is called Octavia.
Menas
True, sir. She was the wife of Caius Marcellus.
Enobarbus
But she is now the wife of Marcus Antonius.
Menas
Pray you, sir?
Enobarbus
‘Tis true.
Menas
Then is Caesar and he forever knit together.
Enobarbus
If I were bound to divine of this unity, I
would not prophesy so.
Menas
I think the policy of that purpose made more in
the marriage than the love of the parties.
Enobarbus
I think so, too. But you shall find the band
that seems to tie their friendship together will be
the very strangler of their amity. Octavia is of a holy,
cold, and still conversation.
Menas
Who would not have his wife so?
Enobarbus
Not he that himself is not so, which is
Mark Antony. He will to his Egyptian dish again.
Then shall the sighs of Octavia blow the fire up in
Caesar, and, as I said before, that which is the
strength of their amity shall prove the immediate
author of their variance. Antony will use his affection
where it is. He married but his occasion here.
Menas
And thus it may be. Come, sir, will you aboard?
I have a health for you.
Enobarbus
I shall take it, sir. We have used our throats
in Egypt.
Menas
Come, let's away.
They exit.
