Chapter 5 layers in investigation of notions of empire and longevity, examined here through the lens of more mundane and pervasive structures—its streets and public highways—to reckon with the attenuated and amalgamated temporalities that these infrastructures construct through the accumulation of large- and small-scale acts of maintenance and repair and the referencing of those interventions by milestone monuments in the extra-urban landscape.

Chapter 6 digs deeper into the textual conventions deployed in many of the monumental inscriptions set up on restored structures. In particular, it points to how they responded to and influenced the experience of the inexorable degradation of time through a rhetoric of ruin and fragmentation that both naturalized and justified the form or extent of rebuilding and in late antiquity shifted to increasingly vivid, sensorially affective forms.

Chapter 3 focuses on the mechanisms through which certain special temple buildings were invested with an essential "prospective" role for empire and how in the face of crisis—especially the physical destruction of the buildings along with the challenge to the claims for continuity and security that came with them—those mechanisms were renewed or transformed.

Buildings frequently change over their lifespans as they are adapted to new needs and affected by damage and decay, yet our approaches to architectural history often fail to account for the material and cultural effects of interventions on existing structures or to pursue the critical questions they raise about temporality and urban environments. The book’s Introduction orients readers to diachronic approaches to architectural history, that is, beyond the moment of initial construction, oriented to the perspective of historical actors. In recognizing moments of architectural revision and rebuilding as inflection points, it stresses the importance of accounting for architectural fabrics composed of variously dated elements and of examining the ways that architectural change shapes audience perception of the site’s history and their own era’s relationship to it. Close examination of two exceptionally long-lasting structures, the Pantheon in Rome and the Hagia Sophia/Ayasofia in Constantinople/Istanbul present a compelling contrast to most modern forms of architectural restoration and illustrate central themes of the book. The chapter situates study of historical architecture within current approaches to cultural time and to material culture and places architectural change in dialogue with text-based approaches to Roman temporality.

The first set of chapters operates at the level of patrons and their communities—imperial and local—to grapple with architectural rebuilding as a mechanism through which shared pasts, presents, and futures were articulated and substantiated. Chapter 1 examines architectural rebuilding as an ideological virtue. In particular, it looks to evidence from Roman and late antique histories, coins, and inscribed statue bases to chart the place and shape of architectural rebuilding (in comparison with and juxtaposition to new construction projects) within the broader commemorative landscape of honor and virtue in cities across the Mediterranean.

Moving from revised buildings’ monumental texts to their material surfaces and spatial arrangements, the book’s final section expands our investigation into "unmarked" ways in which new contexts reframed old elements. Chapter 7 argues that change over time was regularly characterized and symbolized in terms of vividly contrasting architectural substances, in which marble (especially) was used to chart (and critique) urban progress and to modulate a balance between tradition and innovation.

The suite of chapters comprising Part II homes in on monumental building inscriptions as central means through which individual buildings shaped perceptions of their own architectural histories and of temporal change more broadly. The first of these, Chapter 4, investigates assemblages of epigraphic records of architectural interventions that accumulated on buildings over their long ancient lives. The chapter’s analysis of these encrusted epigraphic environments charts a range of strategies that benefactors adopted in setting up their own commemorative texts vis à vis those of earlier patrons and considers the effects of those decisions on the inscriptions’ reception by contemporary audiences.
