John Henderson focuses on three key Letters visiting three Roman villas, and reveals their meaning as designs for contrasting lives. Seneca brings the philosophical epistle to Latin literature, creating models for moralizing which feature self-criticism, parody, and animated revision of myth. The Stoic moralist wrests writing away from Greek gurus and texts, and recasts it into critical thinking in Latin terms, within a Roman context. The Letters embody critical thinking on metaphor and translation, self-transformation and cultural tradition.
