The chapter examines the changing urban landscape of the western Roman Empire and its successor states from approximately 300 to 600. It explores how cities evolved in response to shifting political, economic and social conditions, analysing archaeological evidence and urban-planning trends. The chapter begins with an overview of recent developments in the field and outlines the diverse trajectories of urban centres across the region. Of central importance is the gradual transition from classical urbanism to post-classical forms, marked by the loss and reuse of monumental structures, the fortification of cities and the adaptation of existing infrastructure. Rather than depicting urban change as a straightforward decline, the chapter argues that cities underwent complex transformations, with some centres experiencing contraction while others remained vibrant. It also illustrates how elite participation, religious shifts and administrative restructuring influenced the built environment. Furthermore, attention is given to the role of city walls, which were expanded or reinforced to accommodate new defensive needs. The reuse of materials, including spolia, became a defining feature of late antique architecture. By integrating textual and material evidence, the chapter provides a nuanced perspective on how cities adapted to the challenges of Late Antiquity, maintaining their significance despite profound structural changes.

This overview discusses the development of the catacombs of Rome, focusing on their architectural evolution and their role in Christian burial practices. Tracing the transformation of subterranean cemeteries from the late second to the fourth century, it argues that the catacombs were distinct from contemporary pagan hypogea. Unlike their pagan counterparts, Christian catacombs featured vast networks of interconnected tunnels, a structured layout designed for expansion, and an intensive use of subterranean space. A defining characteristic of these burial sites was the deliberate placement of tombs near those of martyrs, which in turn became focal points for pilgrimage and veneration. The Callixtus catacomb exemplifies this trend, as it was developed with carefully planned access points and designated areas for noble burials. The chapter also challenges earlier assumptions that pagans continued to use catacombs extensively after the legalisation of Christianity. Instead, it argues that these spaces became increasingly exclusive to Christian communities, serving as both burial grounds and sacred spaces that reinforced communal identity and the cult of the martyrs.

This chapter explores the spread of Christianity in Late Antiquity, focusing on archaeological evidence and methodological challenges in tracing its expansion. It examines how Christianity transitioned from a marginalised faith to an institutionalised religion, emphasising regional differences in its adoption across the Mediterranean and beyond. The chapter discusses a variety of materials, including early Christian inscriptions, artefacts, funerary practices and architectural remains such as churches, baptisteries and monasteries. Sites like the house church at Dura Europos and early Christian catacombs provide crucial insights into the religion’s early development. The study also highlights the role of missionary activity and the influence of state policies, particularly after Constantine’s legalisation of Christianity in the fourth century. A major argument is that Christianity spread unevenly, with urban centres adopting it earlier than rural areas. The transition was not uniform, as some regions experienced periods of resistance or syncretism with existing religious traditions. The chapter underscores the difficulty of identifying Christian material culture due to the overlap with pagan symbols. The chapter rounds off by calling for a more critical approach to interpreting archaeological evidence and suggests that future research should focus on regional case studies to refine our understanding of Christianity’s complex expansion.

This chapter examines travel and communication in Late Antiquity, analysing the complexities of movement across the Roman and Byzantine worlds from the third to the eighth century. Rather than viewing this period as one of declining mobility, the chapter argues that travel remained vital, though its dynamics shifted due to political, economic and religious transformations. A major focus is on the infrastructure that supported travel, including roads, bridges, way stations and ports. The cursus publicus, the state-run courier system, is highlighted as a crucial mechanism for imperial communication and administrative efficiency. Trade networks, both maritime and overland, played a fundamental role in sustaining long-distance movement, with Mediterranean seaports, river transport and caravan routes facilitating commercial exchanges. Religious travel, particularly pilgrimage and episcopal councils, became increasingly significant after the rise of Christianity, with the movement of monks, clergy and pilgrims contributing to the spread of religious ideas and artistic traditions. The chapter also addresses migration, discussing the movements of soldiers, officials and entire populations in response to military campaigns, economic opportunities and political upheavals. In this way, this contribution demonstrates that mobility remained central to the late antique world, shaping social, economic and cultural interactions across the empire.

This chapter discusses the evolution of pagan iconography in Late Antiquity, examining how depictions of traditional gods and rituals changed between 300 and 700 CE. It challenges earlier interpretations that associate this period with artistic decline, instead emphasising continuity and transformation in the representation of pagan themes across various media. Drawing on legal, literary, epigraphic and archaeological evidence, the chapter provides a comprehensive perspective on the artistic and religious landscape of the period. It discusses key examples such as the Arch of Constantine, which repurposed older sacrificial motifs, and later fourth-century artworks like the Symmachi ivory diptych, which continued to depict pagan sacrifices despite the growing influence of Christianity. The chapter also examines the selective destruction of pagan imagery, particularly the mutilated reliefs from the Aphrodisias Sebasteion, demonstrating how sacrificial depictions were specifically targeted. The chapter concludes by noting that while sacrificial iconography faded, other pagan motifs – especially those associated with gods like Dionysus and Venus – remained prevalent in mosaics, silverware and textiles. This enduring presence underscores the adaptability of pagan imagery, which continued to influence artistic traditions long after the fall of the Roman Empire.

This chapter examines the production and significance of early Christian sarcophagi, emphasising their role in the development of Christian iconography and funerary practices. It explores a wide range of materials to provide a comprehensive understanding of how these objects were crafted and used. A key argument is that Christian sarcophagi were not a completely new artistic form but evolved from earlier Roman traditions. They were produced using techniques similar to those of their pagan counterparts, with artisans carving reliefs into marble chests, often on commission. However, Christian sarcophagi introduced new imagery, incorporating biblical scenes, martyrs and theological themes that conveyed the Christian hope for resurrection. The chapter challenges the assumption that sarcophagus production declined abruptly, instead demonstrating that Christian sarcophagi remained in use well into the fifth and sixth centuries, particularly in centres such as Rome, Gaul and Constantinople. Ultimately, the chapter argues that early Christian funerary art was both a continuation of tradition and a medium for transformation. Sarcophagi, in particular, were not merely burial containers but also status symbols for the Christian elite, reflecting their social aspirations and religious identity.

This chapter examines the urban development of Alexandria in Late Antiquity, tracing its transformation from a Hellenistic metropolis into a vital centre of Roman and Byzantine administration, commerce and religion. It analyses architectural and archaeological evidence to explore how the city’s infrastructure evolved in response to political shifts and economic changes. Particular attention is given to Alexandria’s grid-plan layout, monumental public buildings and role as a Mediterranean trade hub. The chapter outlines key construction phases, including Ptolemaic urban planning, Roman imperial projects and late antique renovations. Excavations at Kom el-Dikka provide crucial insights into the city’s residential, commercial and academic landscapes, revealing lecture halls, baths and artisanal workshops. This study also examines the impact of religious transformation, documenting the conversion of pagan temples into Christian churches and the rise of new ecclesiastical structures. Further emphasising Alexandria’s role as a major intellectual centre, the study highlights its famous auditoria and the persistence of scholarly activity even after the decline of its classical library tradition. Despite the challenges posed by modern urban expansion, ongoing excavations continue to refine our understanding of Alexandria’s resilience and adaptability in Late Antiquity.

This chapter examines the architectural development of early Christian churches, focusing on their transformation from modest worship spaces into monumental basilicas and centrally planned buildings in Late Antiquity. Drawing on archaeological findings, architectural studies, historical texts and artistic analyses, it traces the evolution of church architecture from the fourth to the seventh century. It argues that early Christian churches did not develop in isolation but were heavily influenced by existing Roman architectural traditions, pointing out that the standard basilica model, with its central nave, aisles and apse, was adapted from Roman civic buildings, while centrally planned churches were inspired by imperial mausolea. The chapter also explores regional variations, such as the preference for polygonal apses in Constantinople and straight-ended churches in North Africa and the Levant, demonstrating how local traditions shaped Christian architecture. A key argument is that church architecture was not only functional but also symbolic, reinforcing Christian identity and imperial authority. The use of precious materials, elaborate mosaics and grand designs reflected the growing prestige of Christianity. The chapter also highlights the influence of emperors, particularly Constantine and Justinian, in shaping the architectural landscape of the early church, setting a precedent for later developments in Byzantine and Western medieval architecture.

This chapter examines the early Islamic period, focusing on the transformation of Iberia, North Africa, the Middle East, Central Asia and Sind following the rise of Islam. It explores how Islamic expansion reshaped these regions, highlighting both continuities with Late Antiquity and the emergence of new cultural, political and religious structures. The chapter discusses vital sources, including chronicles, hadith collections, inscriptions, coins and archaeological findings. It analyses the establishment of early Islamic cities, such as Kufa, Basra and Fustat, and the role of garrison towns in governance. Architectural evidence, including early mosques and urban structures, provides insights into Islam’s growing influence. A central argument is that Islam’s expansion was not an abrupt break from the past but a gradual transformation. Many aspects of administration, language and daily life remained unchanged, while Islam introduced new religious and political dynamics. The chapter also emphasises the role of material culture, including coins and inscriptions, in projecting Islamic identity. In this way, this study illustrates the complex interplay between continuity and change in the early Islamic world, arguing that archaeological research is essential for understanding the period’s long-term developments beyond textual sources.

This chapter explores Byzantine military architecture between 400 and 600, concentrating on the design, function and strategic significance of fortifications. It examines various defensive structures, including urban walls, military forts, civilian refuges and large-scale linear barriers. The chapter argues that fortifications were not merely passive defensive measures but played an active role in military strategy. It challenges the idea that increased fortification indicated imperial weakness, instead asserting that these defensive networks provided greater operational flexibility. Fortifications allowed armies to delay enemy advances, launch counterattacks and protect key urban centres. Additionally, the chapter highlights the evolution of fortification techniques, such as outward-projecting towers, deep ditches, reinforced gate structures and expanded urban wall circuits, demonstrating how these innovations responded to changing military threats. Ultimately, the chapter concludes that Byzantine military architecture was as much about psychological warfare as it was about physical defence. Well-designed fortifications not only deterred invasions but also reinforced imperial authority and boosted the morale of defenders, serving as both strategic and symbolic bulwarks of the empire.

This chapter examines the phenomenon of spolia in Late Antiquity, focusing on the reuse of architectural and sculptural elements in new contexts. It explores examples from Rome, Milan, Ravenna, Thessaloniki and Constantinople, analysing how materials were repurposed for practical, aesthetic and ideological purposes. The contribution differentiates between indiscriminate reuse for construction and the deliberate selection of objects for symbolic or propagandistic reasons. One major discussion centres on the Arch of Constantine (312–15 CE), which incorporates second-century reliefs from monuments dedicated to Trajan, Hadrian and Marcus Aurelius. The chapter considers whether this reuse was driven by practical necessity due to a lack of skilled artisans or intended as an ideological statement aligning Constantine with past emperors. In religious contexts, the Lateran Basilica and Old St Peter’s in Rome reused columns and marbles, transferring imperial grandeur to Christian spaces. This study also investigates the role of spolia in fortifications, with repurposed materials found in city walls, cisterns and military installations. Highlighting how this practice continued into the medieval period, when spolia became more prominent in church facades and mosques, the chapter argues that reuse in Late Antiquity was not simply a result of economic constraints but a deliberate process that shaped architectural and artistic traditions.

This chapter examines glass production in Late Antiquity, with a particular focus on technological advancements, economic significance and regional variations. Drawing on archaeological evidence, chemical analyses, typological studies and historical texts, it traces the evolution of glass manufacturing and distribution across the Roman and Byzantine worlds. The authors argue that glass production in Late Antiquity was highly adaptable, responding to shifts in economic structures, raw material availability and technological innovations. A key factor in this development was the dominance of large-scale glass furnaces in Egypt and the Levant, which supplied raw glass to secondary workshops throughout the empire. The chapter also explores how glassmakers refined shaping and decorating techniques, incorporating blown glass, engraved patterns, gold-leaf applications and coloured blobs. In terms of function, it demonstrates that glass was used across a wide range of contexts, from everyday tableware to luxury drinking vessels, lamps and even windowpanes. Regional differences are evident, with eastern Mediterranean workshops favoring elaborate embellishments, while western traditions drew inspiration from ceramic and metal vessels. A key conclusion is that glass was not only a practical commodity but also a marker of status and innovation.

This chapter examines migration in Late Antiquity, focusing on the movement of peoples and its role in shaping the post-Roman world. It challenges traditional narratives of mass invasions, instead emphasising the complexity of migration processes and their varied effects on political, social and cultural transformations. The chapter draws on archaeological evidence, including settlement patterns, burial practices and material culture, alongside historical sources such as chronicles. It highlights key migration episodes, including the movements of the Goths, Anglo-Saxons and Slavs, analysing how their settlements and artefacts reflect patterns of mobility, integration and adaptation. The chapter also considers new methodologies, such as isotope and aDNA analysis, to refine our understanding of ancient migrations. Central is the notion that migration was not always a violent invasion but often a gradual, negotiated process. While some groups displaced populations, others integrated with existing societies. The chapter stresses that the scale and nature of migration varied and calls for an interdisciplinary approach, combining archaeology, history and scientific methods, to better assess the role of migration in the transition from the Roman world to medieval Europe.

This chapter examines the urban and architectural transformation of Carthage in Late Antiquity, focusing on how the city evolved under Roman, Vandal and Byzantine rule between the fourth and seventh centuries. It discusses Carthage’s role as a political, economic and religious hub in the Mediterranean, emphasising the continuity of its strategic and commercial significance, particularly as a centre for grain production and trade. The study details how Carthage’s harbours, warehouses and marketplaces adapted to shifting imperial priorities. It also explores urban planning, noting how the city’s grid layout, monumental basilicas and elite residences reflected both Roman traditions and late antique adaptations. Religious transformation is another central theme, with a focus on the growth of Christian architecture, including churches, martyr shrines and cemetery basilicas. The chapter reassesses the impact of Vandal rule (439–533 CE), challenging traditional narratives of decline by presenting evidence of continued economic activity and urban maintenance. Under Byzantine rule (533–698 CE), Carthage experienced renewed investment in fortifications, infrastructure and religious buildings, though signs of urban contraction emerged by the seventh century. Thus this chapter demonstrates that Carthage remained a dynamic and resilient city despite political upheavals and its eventual conquest by Islamic forces.

This chapter explores the transformation of coinage in Late Antiquity, examining its economic, political and cultural significance between the third and eighth centuries. It analyses a wide range of numismatic materials, including Roman, Byzantine and early Islamic coinage, to trace how monetary systems evolved in response to imperial policies and economic shifts. The study emphasises the transition from the traditional Roman denarius system to the solidus-based economy introduced by Constantine, in which the solidus became the dominant currency across the Byzantine world. It also examines how coinage functioned as a tool of imperial propaganda. A central argument is that changes in coin iconography reflect broader cultural and religious transformations. The adoption of Christian symbols such as the Chi-Rho and crosses on Byzantine coinage marked a shift from classical motifs to explicitly religious imagery. The chapter also highlights how early Islamic rulers adapted Byzantine coin models, gradually replacing human portraits with inscriptions emphasising monotheism. By considering regional variations, the study examines the persistence of local minting traditions and the interaction between different monetary economies. Thus, it demonstrates that coinage in Late Antiquity was more than a medium of exchange – it was a powerful instrument of ideological messaging and state control.
