The life-work of Augustus and its memory is usually illustrated by the Res gestae as well as the historical pieces of Tacitus, Suetonius and Cassius Dio. This cultural memory omits the Augustus-portrait of the chapters 147–150 of Book 7 of the Naturalis Historia, which summarize the life or more exactly the misfortunes of the life of Rome’s first emperor. This anti-Res gestae divi Augusti is unique not only in ancient literature but in the context of the Naturalis Historia as well. Critics have advocated different explanations. This paper is devoted to an analysis of these chapters in the context of the textual unit that organically contains them, and which culminates in them.
