ABSTRACT
This chapter examines a case-study-or perhaps better, the central case-studyfor issues relating to pollution and marginality in the Roman city, namely the city of Rome itself. Although it involves discussion of literary, epigraphic and legal evidence, the main focus is topographical, as it seeks to assess what the urban layout of Rome, in particular the area which lies between the Servian and Aurelian Walls, might tell us about the activities which are, for one reason or another, excluded from the city.
