How is Mark Antony portrayed in the play "The Tragedy of Julius Caesar"?How is this different to how he is introduced in the play "Antony and...

Antony opens "Julius Caesar" as something of a wild child, during the feast of Lupercal.  He is clearly a favorite of Caesar, as he is asked to touch Julia, the wife of Caesar, so that she might conceive.  While the conspirators realize he is a man of importance to Caesar, they underestimate him, and he proves to be more than a mere limb of Caesar, who can be rendered powerless with out the figurative head of power.  This proves to be fatal mistake in the end.  We see Antony come into his own during the funeral speech.  As power is divvied up, Antony claims what he feels is his, putting him at odds with Octavian, the young, adopted nephew of Caesar. 

As "Antony and Cleopatra" opens, we see an Antony who is in touch with his political power, but the wild child is within sight as he begins this tempestuous affair with the mother of Caesar's son.  He continues in this ill-advised affair that clouds his judgement politically and personally.  Antony believes his own press so to speak because he is a man who is loved by a goddess, which is how Cleopatra is regarded amongst her people.  He, like Caesar, suffers from delusions of grandeur and he, like Caesar, will pay for his hubris with his life.
