In Athens, Athena arranges for Orestes to be tried by a jury of Athenian citizens, with her presiding. The Erinyes appear as Orestes' accusers, while Apollo speaks in his defense. The trial becomes a debate about the necessity of blood vengeance, the honor that is due to a mother compared to that due to a father, and the respect that must be paid to ancient deities such as the Erinyes compared to the newer generation of Apollo and Athena.
