Trojan or Greek

I am trying to view Helen through society's eyes, yet I don't know if I should regard her as Greek or Trojan.. Any ideas?
Thanks,
Amanda

When I'm referring to Ag. and Men. collectively, I know that the plural form of Atride is Atreidae but I'm wondering if they should be called "Atreidae" or "the Atreidae". Thanks.

Tense

If I'm comparing present heroes to past heroes, should I still use the present tense when talking about the Iliad like you said Ms. D, or can I use the past tense since I'm talking about the old way of defining a hero in contrast to the present hero?
