This article analyses how otherness and a politics of affect emerge from the presence of a new Latino migration to Rome, Italy. Looking at processes around Catholic evangelisation and plural migrant itineraries, the paper argues that different and contradictory forces such as narratives of centrality and periphery are mirrored in the presence and history of the Sacred Heart. Exploring and counterposing de Certeau's ideas on migrations and mystics, and the urban as a space of enunciation, I suggest that we should explore a modality of ethnography that combines and mirrors revelatory and analytical apprehensions of the world.
