This chapter explores the question, using primarily epigraphic evidence, whether individual, localized Jewish communities, without any obvious connection to each other across the ethnically, linguistically and religiously diverse Roman Empire, can be said to have had, or displayed, a “micro-identity” in addition to their non-local ethnic one, or whether this feature, if not entirely absent in some cases, was indeed overshadowed by their shared history and ethnic origins. The answer offered: in some cases, maybe.
