An Iris Murdoch poem about a “class” on this play teases a three-volume commentary on this play by Eduard Fraenkel. This play is the source of a saying in its original language that “there is no wisdom without pain.” A woman in this play chastises the chorus for believing a herald but not her “victory-howl.” This play’s title character inspired Civil War general Ezra Mannon in The Homecoming, (15[1])the first play in a cycle by (*) Eugene O’Neill. This play’s (-5[1])protagonist is persuaded by his wife to walk on a carpet of red robes, foreshadowing that she will stab (10[1])him and his lover Cassandra to death in the bathtub, an act that drives the plot of this play’s sequel, The Libation Bearers. For 10 points, name (-5[1])this play in which Clytemnestra murders the title king of Mycenae, the first play of Aeschylus’s Oresteia. (10[1])■END■ (10[1])
