This case study will analyse various ways of integration in the harbour city of Rome through inscriptions, archaeological material, and literary sources, to study how Jewish immigrants and inhabitants of the city were integrated into Roman culture and the urban society of Ostia. To give examples of different ways of integration, we present four inscriptions from Ostia that tell us more about the Jewish inhabitants in the city. These four inscriptions make it possible for us to discuss in greater detail the role of the Jewish inhabitants as members of the Ostian society, their participation in the various activities of the Ostian community, as well as their social roles. For this ‘case study’, the names of the individuals reveal information about both their background and their personal history.
