For what reason does Wolff bring up Aeschylus within the narrative of "Bullet in the Brain"?

By depicting the way in which Anders had been thrilled by his professor's deep understanding of the meaning and context of Aeschylus's work, Wolff is showing that Anders had once recognized great minds alongside his within the world. His professor had shared that Athenian prisoners who could recite Aeschylus had been set free by their Sicilian captors, a detail that had thrilled Anders. He had greatly respected mentors such as his college professor and had found joy in the wonderful ways in which language can act as a form of currency within the world.
