Modern historians often lament how little we can know about some aspects of the ancient world. ‘Just think of what we don’t know about the lives of the poor,’ they complain, ‘or of the perspectives of women.’ This is as anachronistic as it is deceptive. The writers of Roman literature were almost exclusively male; or, at least, very few works by women have come down to us (the autobiography of the emperor Nero’s mother, Agrippina, must count as one of the saddest losses of classical literature).
