Fifteen years ago, historians of the Roman world were in the process of dismantling the hierarchical structure of their subject that had endured since the beginning of scholarly discourse about the Roman Empire. In the late sixties and early seventies, scholars began to move away from work concentrating on the dominant social and political group that had produced the bulk of the surviving literature. They were experimenting with the possibility that groups such as women, slaves, children, peasants, the urban poor, and even soldiers might have a history that was not dictated solely by the interests of people like the younger Pliny. Work by archaeologists, epigraphists and papyrologists had begun to show how it was possible to recover voices from outside the literary tradition. Even within the traditional, philological core of the subject there were signs of change. It was in the late sixties that lively debate erupted over the nature of the Greek literature of the Roman Empire.
