The volume as a whole speaks, very broadly, to the organization of human space in the ancient world. Part I describes over and over the relationship between institutions and individuals; Individuals make up institutions, but institutions alter and mediate behaviors. This is made abundantly clear in Fagan’s article on the ludi while Slootjes’ article shows that the institution of the diocese was incomplete in the fourth century since individuals had not yet been affected by it. The second part focuses on the organization of space and time, the evolution of knowledge, and its organization. Contributors highlight the fundamentally social nature of chronological and geographical space, from the fact that, in Boatwright’s contribution, the Regio VII could become a microcosm of socially-acceptable imperial representations, to the liturgical role that sundials played.
