Quote #10

(Athena) (coming forward now the jurors have finished voting): It is my business in this case to give my judgment last; and I shall cast this vote of mine for Orestes. (She drops it into one of the urns.) I do so because there is no mother who have me birth, and I approve the masculine in everything—except for union with it—with all my heart; and I am very much my father's: so I will set a higher value on the death of a woman who killed her husband, a house's guardian." (734-740)

There you have it, pure sexist prejudice on the part of Athena, patron goddess of Athens. Is there any other good argument for letting Orestes off the hook, aside from this sexist one? If not, why do you think Aeschylus chose to give this idea such prominence at the end of his Oresteia trilogy?
