“A Brief History of Helen of Troy” is a retelling of the Trojan War from the point of view of a Hermione figure. Figures representing Zeus, Clytemnestra, Odysseus, Menelaus, and Paris all amalgamate across the delusions of the forgotten daughter, having been mythologically abandoned with an epic to hear that she cannot participate in. But the play’s strength is beyond the script. The props accumulate across the stage, reminders of the evoked pain. The sets and technicals are starkly professional. The actors’ deliveries are as haunted as the audience’s winces.
