Portia vs. Calpurnia

Portia vs. Calpurnia

Portia and Calpurnia were both noble women during Julius Caesar's time period.  They were both married to men of authority during this time.  Portia was married to Brutus, while Calpurnia was married to Caesar himself.  Although these are some similarities between the two women, there are also differences. 
For example, Portia and Brutus's marriage was based on treating each other as equals.  Calpurnia and Caesar's marriage was typical of the Roman marriages, the man was in charge.  During the play, when Portia asks Brutus to trust her, she wins his trust and slashing her thigh actually has an affect on him.  When Calpurnia tries to tell Caesar to stay home in the play, he agrees with her, but is then very easily persuaded to go to the capital.
In conclusion, Portia and Brutus definitely have the better relationship that would be more welcome during our time period.  Calpurnia and Caesar on the other hand, have the more traditional relationship in the Roman time period.
