In This Study, Marcello Mogetta Examines the Origins and Early Dissemina- Tion of Concrete Technology in Roman Republican Architecture Cambridge University Press 978-1-108-84568-7 — The Origins of Concrete Construction in Roman Architecture Marcello Mogetta Frontmatter More Information THE ORIGINS OF CONCRETE CONSTRUCTION IN ROMAN ARCHITECTURE In this study, Marcello Mogetta examines the origins and early dissemina- tion 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 monu- ments and private domestic architecture that previously have been 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 scientific 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. marcello mogetta is a Mediterranean archaeologist whose research focuses on early Roman urbanism in Italy. He conducts primary fieldwork at the sites of Gabii (Gabii Project) and Pompeii (Venus Pompeiana Project), for which he has received multiple grants from the National Endowment for the Humanities, the Loeb Classical Library Foundation, the AIA, and the Social Sciences and Humanities Research Council. He coordinates the CaLC-Rome Project, an international collaboration that applies 3D mod- eling and surface analysis to the life cycle of ceramic vessels from the Esquiline necropolis in Rome. He is the editor of Élite Burial Practices and Processes of Urbanization at Gabii (JRA Suppl. 108, 2020), and coeditor of A Mid-Republican House from Gabii (2016) and Domitian’s Rome and the Augustan Legacy (forthcoming). © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-108-84568-7 — The Origins of Concrete Construction in Roman Architecture Marcello Mogetta Frontmatter More Information THE ORIGINS OF CONCRETE CONSTRUCTION IN ROMAN ARCHITECTURE TECHNOLOGY AND SOCIETY IN REPUBLICAN ITALY MARCELLO MOGETTA University of Missouri, Columbia © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-108-84568-7 — The Origins of Concrete Construction in Roman Architecture Marcello Mogetta Frontmatter More Information University Printing House, Cambridge cb2 8bs, United Kingdom One Liberty Plaza, 20th Floor, New York, ny 10006, USA 477 Williamstown Road, Port Melbourne, vic 3207, Australia 314–321, 3rd Floor, Plot 3, Splendor Forum, Jasola District Centre, New Delhi – 110025, India 79 Anson Road, #06–04/06, Singapore 079906 Cambridge University Press is part of the University of Cambridge.

SCOTT**, ANN GLENNIE*, ALLISON SMITH* COSA (ORBETELLO, GR): 70 YEARS OF EXCAVATIONS AND NEW DIRECTIONS Le Terme pubbliche di Cosa, localizzate al centro del tessuto urbano della colonia, sono oggetto di indagini da parte della Florida State University a partire dal 2013. Gli scavi sono condotti con lo scopo di mettere a fuoco la funzione e il ruolo dell’esteso complesso, utilizzato tra il I e il II secolo d.C., e di comprendere a pieno le soluzioni tecniche adottate dai coloni per risolvere i problemi di approvvigionamento idrico. Le attività di indagine stratigrafica sono supportate da una campagna di rilievo di ortofoto funzionali alla ricostruzione dello scavo, di indagini geofisiche e di ricostruzione paleoambientale. INTRODUCTION: HISTORY OF THE EXCAVATIONS AND OF THE COLONY This year we celebrate an important milestone, with the past excavation season (2018) marking the 70th anniversary of investigation at the site of Cosa1. For many years the flagship of American archaeology in Italy, study of Cosa began in 1948 under the auspices of the American Academy in Rome and the direction of Frank Brown. Brown and his students conducted a series of campaigns between the 1950s and 1980s and investigated major environs of the colony including the Forum2, the Arx3, the Port4, and some house blocks5. 1) Thanks to the Soprintendenza Archeologia, Belle Arti e Paesaggio per le province di Siena, Grosseto e Arezzo for inviting us to present the ongoing work at Cosa.

  • Roman Population Size: the Logic of the Debate
    Princeton/Stanford Working Papers in Classics Roman population size: the logic of the debate Version 2.0 July 2007 Walter Scheidel Stanford University Abstract: This paper provides a critical assessment of the current state of the debate about the number of Roman citizens and the size of the population of Roman Italy. Rather than trying to make a case for a particular reading of the evidence, it aims to highlight the strengths and weaknesses of rival approaches and examine the validity of existing arguments and critiques. After a brief survey of the evidence and the principal positions of modern scholarship, it focuses on a number of salient issues such as urbanization, military service, labor markets, political stability, living standards, and carrying capacity, and considers the significance of field surveys and comparative demographic evidence. © Walter Scheidel. [email protected] 1 1. Roman population size: why it matters Our ignorance of ancient population numbers is one of the biggest obstacles to our understanding of Roman history. After generations of prolific scholarship, we still do not know how many people inhabited Roman Italy and the Mediterranean at any given point in time. When I say ‘we do not know’ I do not simply mean that we lack numbers that are both precise and safely known to be accurate: that would surely be an unreasonably high standard to apply to any pre-modern society. What I mean is that even the appropriate order of magnitude remains a matter of intense dispute. This uncertainty profoundly affects modern reconstructions of Roman history in two ways. First of all, our estimates of overall Italian population number are to a large extent a direct function of our views on the size of the Roman citizenry, and inevitably shape any broader guesses concerning the demography of the Roman empire as a whole.

    Brief History of the Roman Empire -Establishment of Rome in 753 BC (or 625 BC) -Etruscan domination of Rome (615-509 BC) -Roman Republic (510 BC to 23 BC) -The word 'Republic' itself comes from the Latin (the language of the Romans) words 'res publica' which mean 'public matters' or 'matters of state'. Social System -Rome knew four classes of people. -The lowest class were the slaves. They were owned by other people. They had no rights at all. -The next class were the plebeians. They were free people. But they had little say at all. -The second highest class were the equestrians (sometimes they are called the 'knights'). Their name means the 'riders', as they were given a horse to ride if they were called to fight for Rome. To be an equestrian you had to be rich. -The highest class were the nobles of Rome. They were called 'patricians'. All the real power in Rome lay with them. Emperors of the Roman Empire -Imperial Period (27BC-395AD) Augustus: Rome's first emperor. He also added many territories to the empire. Nero: He was insane. He murdered his mother and his wife and threw thousands of Christians to the lions. Titus: Before he was emperor he destroyed the great Jewish temple of Solomon in Jerusalem. Trajan: He was a great conqueror. Under his rule the empire reached its greatest extent. Diocletian: He split the empire into two pieces - a western and an eastern empire. -Imperial Period (27BC-395AD) Hadrian: He built 'Hadrian's Wall' in the north of Britain to shield the province from the northern barbarians.

  • Ancient Concrete Works
    Ancient concrete works Amelia Carolina Sparavigna Dipartimento di Fisica Politecnico di Torino It is commonly believed that the ancient Romans were the first to create and use concrete. This is not true, as we can easily learn from the Latin literature itself. For sure, Romans were able to prepare high-quality hydraulic cements, comparable with the modern Portland cements. In this paper, we will see that the use of concrete is quite older, ranging back to the Homeric times. For instance, it was used for the floors of some courts and galleries of the Mycenaean palace at Tiryns. Introduction On April 12, 2011, in concurrence with an exhibition in the Oxford’s Ashmolean Museum of some ancient treasures of Greece, the BBC announced that Macedonians created cement three centuries before the Romans [1]. Unearthing some tombs of a royal complex belonging to Alexander the Great and his father Philip, at Vergina, archaeologists determined that Macedonians were “not only great warriors but revolutionary builders as well“, since they used concrete before the Romans. This information is quite interesting because shows the location of an early use of concrete. Unfortunately, if we want to shed light on the origin of the material, this simple comparison between Macedonian and Roman concretes is a little bit misleading. Moreover, it is raising another question: were Macedonians the first people using concrete? The answer is negative. Concrete was older even than Alexander the Great. Let me show you how we can deduce this fact from some Latin essays and their English translations and from the reports of Schliemann’s excavations of Mycenaean archaeological sites.

  • The Population of Cisalpine Gaul in the Time of Augustus1
    The Population of Cisalpine Gaul in the time of Augustus1 In order to put the arguments of this article into a realistic perspective, I want to start by making it clear that we do not know and will never know for certain how many people lived in Cisalpine Gaul during the late Republic and early Empire.2 In theory, then, this could be the shortest article on ancient demography ever written. The reason why I have nevertheless decided to devote a short piece to this seemingly unpromising topic is quite simply that there are, in my view, many interesting things to say about the population of Cisalpine Gaul that have never been said before. It is also my contention that even though the new considerations that will be put forward in this paper do not in any way prove a low-count interpretation of Italy’s demographic history to be correct, they at least highlight some difficulties in the high count that have not received the attention they clearly deserve. My attempt to shed new light on these issues will centre on the shape of the urban network and on the size of the aggregate urban population. I shall begin by looking at the physical size of the towns of Cisalpina and by examining some of the variables that are likely to have influenced the number of town-dwellers per hectare. My next step will be to discuss briefly the problem of urbanization rates. In theory, if it were possible for us to recover both the approximate number of town-dwellers (POPurb) and the overall urbanization rate (URB.RATE) for Cisalpina, the overall population of the North could be extrapolated from the urban population, using the following formula: POPtot = (100: URB.

    The Committee on Ancient Roman Concrete, JSCE (Com-No. 114) Mt. Vesuvius The Committee on Roman Concrete (Com-No. 114) is one of the special subcommittees in the Concrete Committee, Japan Society of Civil Engineers (JSCE). This committee has been chaired by Prof. E. Sakai, Tokyo Institute of Technology, and advanced by seven active members. Also, this committee is supervised by Dr. M. Aoyagi, Director-general of the National Museum of Western Art of Japan and Dr. Matsuyama, University of Tokyo. Pompeii The purpose of this committee is to investigate the long-term durability of concrete, focusing especially on the material phase. In addition, the important mission of this committee is to reflect the results of these investigations for the development of society, public welfare, growth of civil engineering, and concrete engineering. This committee also relates to the standard specifications for design and construction of concrete structures such as huge concrete structures for storage of nuclear waste which Ancient Roman Concrete in Pompeii greatly require long-term durability performance. It is well known that concrete deteriorates due to rain, CO2 in the air, and chloride ion in seawater. Therefore, the properties of concrete remarkably change due to their long history of exposure condition, although their performances were the same at the initial stage. From these viewpoints, it is quite important to collect as much aged concrete samples as possible. Ancient Roman concrete would Huge concrete structures for storage of surely contain many useful and important nuclear waste in Japan information.
