"Concrete construction represents Rome's major contribution to the history of ancient architecture and engineering. Scholars have touted the modern character of this man-made material, which gave planners the ability to cast structures wherever they were needed, emphasizing the inextricable link between building medium and building forms. Observation of the durability and longevity of concrete features, and particularly their survival in hostile environments such as seawater, has stimulated the scientific study of the material in order to identify the constituent elements and to describe the mechanical, chemical and physical characteristics for possible reproduction. As a result, the systematic testing of ancient samples has greatly improved our understanding of how Roman builders of the Late Republican and Imperial periods exploited raw materials. Moreover, the approach has shifted to concentrate on the step-by-step examination of the construction process, and standardized procedures have been developed to quantify the costs of construction, thus allowing for a contextualization of the building industry within the broader Roman economy"--

In this study, Marcello Mogetta examines the origins and early dissemination of concrete technology in Roman Republican architecture. Framing the genesis of innovative building processes and techniques within the context of Rome's early expansion, he traces technological change in monumental construction in long-established urban centers and new Roman colonial cites founded in the 2nd century BCE in central Italy. Mogetta weaves together excavation data from both public monuments and private domestic architecture that have been previously studied in isolation. Highlighting the organization of the building industry, he also explores the political motivations and cultural aspirations of patrons of monumental architecture, reconstructing how they negotiated economic and logistical constraints by drawing from both local traditions and long-distance networks. By incorporating the available evidence into the development of concrete technology, Mogetta also demonstrates the contributions of anonymous builders and contractors, shining a light on their ability to exploit locally available resources.

One marker of the majesty of ancient Rome is its surviving architectural legacy, the stunning remains of which are scattered throughout the circum-Mediterranean landscape. Surprisingly, one truly remarkable aspect of this heritage remains relatively unknown. There exists beneath the waters of the Mediterranean the physical remnants of a vast maritime infrastructure that sustained and connected the western world’s first global empire and economy. The key to this incredible accomplishment and to the survival of structures in the hostile environment of the sea for two thousand years was maritime concrete, a building material invented and then employed by Roman builders on a grand scale to construct harbor installations anywhere they were needed, rather than only in locations with advantageous geography or topography. This book explains how the Romans built so successfully in the sea with their new invention. The story is a stimulating mix of archaeological, geological, historical and chemical research, with relevance to both ancient and modern technology. It also breaks new ground in bridging the gap between science and the humanities by integrating analytical materials science, history, and archaeology, along with underwater exploration. The book will be of interest to anyone interested in Roman architecture and engineering, and it will hold special interest for geologists and mineralogists studying the material characteristics of pyroclastic volcanic rocks and their alteration in seawater brines. The demonstrable durability and longevity of Roman maritime concrete structures may be of special interest to engineers working on cementing materials appropriate for the long-term storage of hazardous substances such as radioactive waste. A pioneering methodology was used to bore into maritime structures both on land and in the sea to collect concrete cores for testing in the research laboratories of the CTG Italcementi Group, a leading cement producer in Italy, the University of Berkeley, and elsewhere. The resulting mechanical, chemical and physical analysis of 36 concrete samples taken from 11 sites in Italy and the eastern Mediterranean have helped fill many gaps in our knowledge of how the Romans built in the sea. To gain even more knowledge of the ancient maritime technology, the directors of the Roman Maritime Concrete Study (ROMACONS) engaged in an ambitious and unique experimental archaeological project – the construction underwater of a reproduction of a Roman concrete pier or pila. The same raw materials and tools available to the ancient builders were employed to produce a reproduction concrete structure that appears to be remarkably similar to the ancient one studied during ROMACON’s fieldwork between 2002-2009. This volume reveals a remarkable and unique archaeological project that highlights the synergy that now exists between the humanities and science in our continuing efforts to understand the past. It will quickly become a standard research tool for all interested in Roman building both in the sea and on land, and in the history and chemistry of marine concrete. The authors also hope that the data and observations it presents will stimulate further research by scholars and students into related topics, since we have so much more to learn in the years ahead.

Since antiquity, Roman architecture and planning have inspired architects and designers. In this volume, Diane Favro and Fikret Yegül offer a comprehensive history and analysis of the Roman built environment, emphasizing design and planning aspects of buildings and streetscapes. They explore the dynamic evolution and dissemination of architectural ideas, showing how local influences and technologies were incorporated across the vast Roman territory. They also consider how Roman construction and engineering expertise, as well as logistical proficiency, contributed to the making of bold and exceptional spaces and forms. Based on decades of first-hand examinations of ancient sites throughout the Roman world, from Britain to Syria, the authors give close accounts of many sites no longer extant or accessible. Written in a lively and accessible manner, Roman Architecture and Urbanism affirms the enduring attractions of Roman buildings and environments and their relevance to a global view of architecture. It will appeal to readers interested in the classical world and the history of architecture and urban design, as well as wide range of academic fields. With 835 illustrations including numerous new plans and drawings as well as digital renderings.

Concrete Vaulted Construction in Imperial Rome examines methods and techniques that enabled builders to construct some of the most imposing monuments of ancient Rome. Focusing on structurally innovative vaulting and the factors that influenced its advancement, Lynne Lancaster also explores a range of related practices, including lightweight pumice as aggregate, amphoras in vaults, vaulting ribs, metal tie bars, and various techniques of buttressing. She provides the geological background of the local building stones and applies mineralogical analysis to determine material provenance, which in turn suggests trading patterns and land use. Lancaster also examines construction techniques in relation to the social, economic, and political contexts of Rome, in an effort to draw connections between changes in the building industry and the events that shaped Roman society from the early empire to late antiquity. This book was awarded the James R. Wiseman Book Award from the Archaeological Institute of America in 2007.

A survey of building techniques & architecture from the 3rd century B.C. through the fifth century A.D., this volume explores how the Greeks of the classical period & later the Romans created a complex & innovative built environment.

With 835 illustrations including numerous new plans and drawings as well as digital renderings.

This book on Roman construction explains why and how Roman builders employed a set of unusual vaulting techniques and explores why each is confined to a particular area of the Empire. It is written to be accessible to advanced students as well as experts in the field.

This book presents the legislation that formed the basis of Roman law - The Laws of the Twelve Tables. These laws, formally promulgated in 449 BC, consolidated earlier traditions and established enduring rights and duties of Roman citizens. The Tables were created in response to agitation by the plebeian class, who had previously been excluded from the higher benefits of the Republic. Despite previously being unwritten and exclusively interpreted by upper-class priests, the Tables became highly regarded and formed the basis of Roman law for a thousand years. This comprehensive sequence of definitions of private rights and procedures, although highly specific and diverse, provided a foundation for the enduring legal system of the Roman Empire.
