Tim Vasen on "Troy: After and Before"

At McCarter’s Berlind Theatre, two ancient Greek plays explore a bloody story tying family values to international politics. In “Iphigenia at Aulis” by Euripides, Iphigenia is sacrificed by her father for the cause of war; in “Agamemnon” by Aeschylus, his life is taken in turn. Susan Wallner talks to Princeton University director Tim Vasen about the production and its relevance to today’s headlines.
