This chapter examines the role of technology in Late Antiquity. It challenges the traditional view that the period was marked by technological stagnation. It argues that instead of focusing solely on innovation, historians should consider the continued use, adaptation and repurposing of existing technologies. It also highlights the survival and refinement of older methods, emphasising that technological choices were often influenced by social, political and environmental factors rather than pure efficiency. One of the chapter’s central discussions focuses on military technology, particularly the development of catapults. Analysing textual sources such as Vegetius’ Epitoma rei militaris and De rebus bellicis alongside archaeological evidence, the study reveals that military engineering remained highly sophisticated. The construction of catapults, their adaptation for different battlefield scenarios, and the organisation of state-run fabricae (weapons workshops) demonstrate that technological knowledge continued to be refined. Additionally, the chapter critiques the historiographical tendency to equate technological progress with economic growth, arguing that many technological decisions were driven by factors beyond economics. It concludes that Late Antiquity was not a period of decline but one of transformation, in which technological continuity and adaptation played a crucial role in maintaining societal structures.

The artes, in the sense of systematic treatises on various disciplines of specialized knowledge, are not well understood today because they are usually studied in isolation from one another. This book argues that the artes of the early Roman Empire—the period of the greatest flourishing of this kind of literature—belong to a common intellectual culture and ought to be studied together. Their unity stems ultimately from a shared preoccupation with relating theory to practice vis-à-vis disciplinary expertise. Within the artes, the theory–practice problem stimulated the emergence of theories of knowledge and theories of nature embedding Roman specialized knowledge in a broader understanding of the world. Indeed, the artes crystallize a uniquely Roman scientific culture that has not been previously recognized as such. The aim of this book is to study this scientific culture.

The artes of the early Roman Empire are much more than manuals or handbooks intended to communicate the elements of practical expertise: they are vehicles for the articulation of Roman understandings of nature, knowledge, and society. This intellectual culture is premised on a theoretically sophisticated notion of ars that developed in the late Republic. It deserves to be regarded as a scientific culture because inter alia the artes elaborate different theories of nature and knowledge, draw upon many branches of ancient scientific inquiry, and employ methods characteristic of ancient scientific thought and practice. The artes Romanize specialized knowledge insofar as they plot their scientific contents along the geographic and temporal axes of Roman power. Ultimately, the artes constitute a unified intellectual phenomenon and should be studied as a part of the scientific culture to which they belong.

This chapter traces key moments in the rhetorical tradition in the context of which the problematic relationship of difference and similarity between rhetorical and poetic discourse is evoked and discussed. The competing claims of affinity and difference between poetic and rhetorical discourse in Gorgias’ Helen, Isocrates, Aristotle, Cicero, Kant and others are analyzed as aspects of rhetoric’s self-definition.

This chapter focuses on the strategic evocation of the appropriate boundaries between rhetorical and poetic speech in Quintilian’s Institutio Oratoria. If Quintilian’s exhortation to use poetic models judiciously in books 8 and 10 is read side by side with his elaborate deployment of poetic metaphors to represent both his work and that of the orator throughout the work, a far more complex picture emerges, one in which poetry is not simply a repository of sentences to be emulated but a source of cultural authority to be subsumed by the rhetorical medium.
