This book explores how Virgil uses his three major works to construct a systematic, evolving discourse on the nature of virtue, authority, and moral responsibility in the new Augustan world. The trajectory of his poetic career is itself a deliberate moral and artistic ascent, mirroring the traditional rota Virgilii (the wheel of Virgil) that moves from the humble, low-style pastoral world to the middle style of agricultural epic, and finally to the high style of national foundation myth. In each of these generic spaces, Virgil redefines what it means to be a moral agent in a changing political landscape.
