This chapter examines the concept of heresy through the growth of papal decretals, canon law and conciliar legislation during the High and Late Middle Ages (eleventh to fifteenth centuries). It explores the growth of medieval heresy during a period of burgeoning papal power and examines how popes both reacted to and constructed ideas of heresy and heretics.

The rapid development of international law post-World War II also coincided with greater reliance upon treaties as a source of international law. Treaties had always been recognised as a source of international law, and their status was confirmed in art 38 of the ICJ Statute. It was the development of the UN, with its emphasis upon international law and focus upon treaty-making as a means of not only peaceful resolution of disputes but also multilateral agreement between States on matters of common concern, that was the catalyst for a greater reliance upon treaties in the conduct of international relations. This chapter begins by examining the growth of treaty-making, before considering what a treaty is, including the nature of 'instruments of less than treaty status'. It then covers treaty negotiation, creation and entry into force; reservations, objections and declarations to treaties; and legal obligations arising once a treaty has entered into force. The chapter then turns to treaty interpretation, and then examines how treaties are voided or ended through invalidity, suspension or termination. The chapter concludes with a discussion of amendment and modification of treaties.

This chapter explores late antique portraiture, centring on its stylistic evolution, its cultural significance and shifting scholarly interpretations. It examines a diverse range of materials, including sculptural portraits, reliefs, mosaics and coins, alongside historical texts that shed light on how portraiture was perceived and utilised during this period. The chapter traces the transition from the naturalistic imperial portraiture of the Roman era to the more stylised and symbolic depictions of the Late Antique and Byzantine periods. It analyses how portraiture evolved from realistic likenesses to abstract, hierarchical representations, particularly as a response to Christianity’s growing influence and the changing political landscape, and argues that late antique portraits should be viewed not as signs of artistic decline but rather as part of a broader transformation in both artistic and ideological expression. The chapter concludes that portraiture in Late Antiquity was not merely about depicting individuals; it played essential political, religious and social roles, reinforcing imperial authority and Christian ideals.

This chapter examines the transition of pagan architecture and religious practices in Late Antiquity, focusing on the treatment of Roman temples under Christian emperors. Drawing on legal texts, literature, inscriptions and archaeological findings, it evaluates whether temples were preserved, repurposed or destroyed. Challenging the common assumption of widespread temple destruction, it argues that such actions were neither systematic nor state-enforced. Instead, the chapter presents a nuanced perspective, demonstrating that many temples remained intact and were gradually adapted for secular or Christian purposes. Archaeological evidence suggests that abandonment and natural decay played a greater role in their decline than deliberate demolition. It also highlights how Christian emperors often sought to suppress pagan rituals while preserving architectural heritage, with legal measures typically prohibiting sacrifices rather than mandating temple destruction. By emphasising regional variations in temple transformations and critically assessing sources that exaggerate instances of destruction, the chapter challenges traditional narratives, offering a more complex understanding of religious and architectural change in Late Antiquity.

This chapter examines the reciprocal accusations of heresy between the Byzantine East and Latin West: such accusations were only sporadically made during the first millennium but increased exponentially from the twelfth century onwards on the Byzantine side and, to a lesser extent, from the thirteenth century on the Latin side (where they were generally subsumed under the accusation of schism or ‘disobedience’). The notions of ‘heretic’ and ‘schismatic’, which ought to be distinct and precisely defined according to canon law, increasingly overlapped within the polemical discourse and were collectively applied to the opposite population, in a process of construction of religious otherness.

This chapter explores the development of funerary archaeology in Late Antiquity, examining how burial practices evolved and how they have been interpreted over time. It argues that these practices were far more complex than previously assumed, shaped by a range of factors including religious beliefs, social status and local traditions. The chapter challenges earlier assumptions that grave goods were exclusively linked to pagan burials, demonstrating that Christians also placed objects in graves. It also examines the influence of nationalism and antiquarianism on the interpretation of burial sites, particularly in the nineteenth and early twentieth centuries. One of its key conclusions is that burial practices varied significantly and cannot be neatly categorised along religious or ethnic lines. Additionally, cemeteries served not only as places of interment but also as spaces for reinforcing social identity, political claims and communal memory. By integrating modern archaeological techniques with historical analysis, the chapter offers a more nuanced understanding of late antique funerary customs, moving beyond simplistic narratives of religious transformation.

Chapter 1 provides an overview of the central argument of the book. Medical anthropology, psychology, and psychiatry must steer a course between realism and constructivism, integrating the useful features of both perspectives. Metaphor theory and 4-E cognitive science provide ways of integrating cognitive and socio-cultural processes. Metaphor production and comprehension involves cognitive and emotional processes embodied and enacted through rhetoric and social discourse. These practices constitute a hermeneutic circle that can be traced from body to person to social world and back. They show how symbols and things live in the same world. This work has implications for understanding the ways illness experience and healing practices are embedded in larger systems of knowledge/power. The metaphors that arise in individuals’ struggles to make sense of their predicaments and to heal from affliction are borrowed from everyday concepts of mind and body, as well as the political language of power, resistance, and dissent. Every metaphor lends power to a particular view of the world. We must judge the value of metaphors on their moral, political, aesthetic, and pragmatic implications.

This chapter examines the relationship between the Roman Empire and northern European ‘barbarian’ societies from the fourth to the mid seventh century, challenging the view that they were entirely separate. Instead, it argues that these regions remained deeply interconnected with Rome, even after the empire’s collapse. The discussion draws on archaeological evidence – settlements, burial customs and trade patterns – alongside historical sources like Gregory of Tours and Tacitus. Findings reveal growing Roman cultural influence in barbarian lands, reflected in changing burial rites, settlement structures and material culture. Roman imports in Germanic territories and diplomatic payments to frontier leaders further highlight this integration. The chapter contends that Rome’s fall was not a sudden rupture but a gradual transformation that reshaped northern Europe’s political landscape. The rise of new confederacies, including the Franks, Alamanni and Saxons, underscores this shift. Additionally, the chapter explores the spread of Christianity and its role in shaping post-Roman societies. Rather than viewing ‘barbarian migrations’ as simple population movements, the study emphasises a complex interplay of Roman policies, local power struggles and cultural evolution. A key takeaway is that Northern Europe’s integration into the post-Roman world was a fluid process, in which continuity and change coexisted.

I met Kilalo, then ninety years old, for the first time in 2010. He lived – and was later buried – in one of the villages that make up Monigi. Back then, it was close to the city, but still Goma’s rural hinterland. Since that time, the city of Goma has been rapidly encroaching on Monigi, as recurrent waves of violence have brought ever more people to the city in search of refuge. From the entrance of Kilalo’s small house, Rwanda was always visible, even if during the dry season the dust in the air only revealed the contours of its first hills. During one of our first conversations, he told me: “When my friend from Rwanda comes here, and I have a piece of land, why not give it to him? Like today, the Congolese refugees who are in Rwanda, they also went without UNHCR [UN’s Refugee Agency].”
