Antony and Cleopatra - Regions

In the context of Antony and Cleopatra, I do believe that Egypt is an "other" region. The only characters that go back and forth between Rome and Egypt constantly are Antony and Enobarbus, who both ultimately meet their deaths. This indicates that Egypt is not a good place to be when you're a Roman. And yes, Cleopatra and Charmian both commit suicide due to their involvement with the Romans. I believe that this shows that Egypt and Rome should be singular. Due to the way Shakespeare portrays Egypt, I believe he wants to hold it up as an equal to Rome. Just look at the way Enobarbus talks about Egypt in this quote:

"I will tell you.

The barge she sat in, like a burnished throne,

Burned on the water. The poop was beaten gold;

Purple the sails, and so perfumed that

The winds were love-sick with them; the oars were 

silver,

Which to the tune of flutes kept stroke, and made

The water which they beat to follow faster,

As amorous of their strokes. For her own person,

It beggar'd all description: she did lie

In her pavilion—cloth-of-gold, of tissued— 

O'erpicturing that Venus where we see

The fancy out-work nature. On each side her

Stood pretty dimpled boys, like smiling Cupids,

With divers-colored fans, whose wind did seem

To glow the delicate cheeks which they did cool,

And what they undid did. (2.2.226-242)"

This beautiful description of Egypt and its ruler is never made in regards to Rome. Though the other characters may see Egypt and it's queen as a vile place, Shakespeare wants to portray it in a way that makes us root for its success. 

I believe some of Antony's admiration toward Cleo is due toward her charm and character. She constantly is manipulating him to "love" her. Though I think part of his attraction toward her is due to the decadence that comes with being a powerful individual in Egypt. Does he actually love her? I don't know. I don't think so but hey who am I to say.

If anything, I think Antony completely burns the bridges that connect Egypt and Rome. Though during the end of the play, Caesar tries to make amends with Cleopatra (see quote) and exist peacefully, but Antony's postmortem influence over Cleo is what ultimately causes her to commit suicide. Ultimately, I think it's the leaders of each region that determine how relations are. Part of the conflict, I think, is that Antony is Alexandrian, but his duty is toward Rome. This, I believe, is ultimately the biggest conflict of the play. There is no way to get away from your identity without considerable effort, and as a influential Roman after the death of Julius, he cannot be an Alexandrian no matter how hard he tries.

CAESAR QUOTE:
"You may see, Lepidus, and henceforth know,
It is not Caesar's natural vice to hate
Our great competitor. From Alexandria
This is the news: he fishes, drinks, and wastes
The lamps of night in revel, is not more manlike
Than Cleopatra, nor the queen of Ptolemy
More womanly than he; (1.4.1-7)"
