From Robert Knapp’s Invisible Romans, which brings to light the laboring men, housewives, prostitutes, freedmen, slaves, soldiers, and gladiators who formed the backbone of the ancient Roman world, and the outlaws and pirates who lay beyond it, all in the face of a persistent historical truth: “Over the centuries, concentration of wealth in the hands of a few has been the norm, rather than the exception.”

I have searched for a term to capture the invisible demographic group that is the subject of this book and have chosen to call them “ordinary people.” This distinguishes them from the elite and leaves their definition open to the wide range of their existence, from fairly wealthy to modestly well-off and downright poor, male and female, slave and free, law-abiding and outlaw. These ordinary people lived in a world dominated by a tiny, self-perpetuating elite that was limited and defined by wealth, tradition, blood, and power. They belonged to one of the three orders or ordines into which they divided themselves. The senatorial order was the most exalted in social and political terms but not always the wealthiest. The equestrian order focused on the acquisition of wealth rather than the power and rank of the senatorial order. The decurial order ran towns and cities across the empire and mirrored the senatorial-equestrian divisions of Rome; these men were generally less wealthy than members of senatorial-equestrian orders, although sometimes local decurials were also equestrians. The three orders amounted to no more than 100,000–200,000 people, less than half a percent of the empire’s population of 50–60 million. Among them only the adult males counted; these numbered about 40,000 and so, as the empire at this time was roughly 2.5 million square miles, there was on average one adult member of the male elite for every sixty or so square miles. As the elites were concentrated in Rome, the proportion elsewhere was even lower. Yet these numerically minuscule and widely scattered leaders controlled almost everything.
