Book excerpt: A study of the last drama of Aeschylus' trilogy concerned with the fortunes of the house of Laius that ends with the story of Oedipus' sons, the enemy brothers, who self-destruct in mutual fratricide but thereby save the besieged city of Thebes. The book's findings, however, far exceed these limits to explore the relationships between language and kinship, as between family and city, self and society, and Greek ideas about the nature of human development and identity.
