During my stay in London, I shall be investigating the symbolic rôle and function of foreigners in imperial Rome. The demography of Rome's non-citizen population recently has been studied intensively; departing from this research, I want to include questions of imperial self-representation, but also the impact of cosmopolitanism on the ways foreigners were incorporated in - or excluded from - the public life in imperial Rome. At the same time, different models of being foreign in imperial Rome - integration, separation, but also rôle-switching according to different contexts, will come into view. It is my hope to come into contact with other researchers in London sharing my interest in the various facets of being a legal alien in an imperial capital.
