Archaeology and conservation at Herculaneum: from the Maiuri campaign to the Herculaneum Conservation Project

Abstract

This article looks at two periods in the history of the archaeological site of Herculaneum (Italy) and the role of the archaeologist there. Amedeo Maiuri was in charge of the first major excavation campaign that uncovered the site from 1927 to 1961, but was also responsible for the site's restoration, presentation and maintenance. Much can be learnt from his approach, particularly with regard to site management – a fixed team of specialists continuously cared for the site – and his creation of what was effectively an open-air museum. The second example looks at the author's experiences with the Herculaneum Conservation Project, where the emphasis is on conservation interventions rather than excavation, but where the archaeologist has an important role in the conservation team and also has the opportunity to make new archaeological discoveries. The article concludes that the role of the archaeologist must evolve to include a professional responsibility for archaeological heritage that extends beyond its excavation.     

The Herculaneum Conservation Project: Introduction

Abstract

This short text places the archaeological site of Herculaneum, Italy and the Herculaneum Conservation Project in context, and introduces the volume of articles on this subject. The author outlines the importance of the site, and the public/private partnership that was launched in order to tackle the problems of decay there.     

A Methodological Approach Towards Conservation

Abstract

Since conservation became a recognized discipline, professionals involved in conservation projects have tried to find the best criteria for their interventions. Often these criteria remain quite vague, based on the idea that every historic building has its own special conditions, which make its problems different from other buildings. This conviction, which is appropriate at one level, has serious consequences due to the lack of a consistent methodology. More than a lack of criteria, we might talk about a lack of 'habit' in identifying values in the Mediterranean region: the concept of values is much more widespread in Anglo-Saxon countries.

If we take a look at the history of conservation, there are a number of cases which are often used as models: for example, the Colosseum or the Arch of Titus in Rome, both interventions which are greatly admired and included in many conservation manuals. More recently there are projects which are widely accepted by the heritage conservation community as well: the paper explores the Palace of the Partal (Granada), the Villa Romana del Casale (Piazza Armerina), the theatre at Orange, and the Insula Orientalis I in Herculaneum. In this article, I suggest that there are constant elements within these conservation projects, reflecting typological, structural, constructional, functional, aesthetic, formal, historical, and symbolic values. These features represent a way of planning a conservation project and a critical methodology to judge the outcomes of the project in an objective manner. The methodology is qualitative rather than quantitative. All historic buildings have a set of values developed from their origins and throughout their history. These values can be analysed to extract the most important elements to be preserved. Analysing the values of our built heritage will allow us to create better decision-making processes.     

Balancing Archaeological Responsibilities and Community Commitments: A Case from Honduras

Abstract

Exploring the implications of a recent discovery in NW Honduras, this paper considers the ethical dilemma that arises when an archaeologist's responsibility to disseminate information conflicts with her/his commitment to protect cultural resources. We suggest that applied archaeology that benefits local communities among which investigations are conducted is a first step toward developing long-term solutions to conservation and stewardship challenges.     

Site Conservation in Morocco: The Emergence of a Practice at Aghmat

Abstract

It is still uncommon for foreign and national archaeological excavations in Morocco to include architectural or site conservators during the excavation and post-excavation periods. The few existing examples of conservation have all been carried out long after the site or the building had been excavated. The site conservation activities during the Aghmat excavations in summer 2006 illustrate how the presence of archaeological conservators, advising the archaeological team and implementing urgent interventions, has ensured a safe excavation and has contributed to the preservation of the physical integrity of the excavated buildings. The excavation of the imposing archaeological features of the medieval bath of Aghmat provided the first opportunity in Moroccan archaeology for Moroccan archaeological conservators to be involved in condition assessment, planning, and provision of conservation activities to preserve the bath.

The primary aim of this paper is to present the site conservation experience in the Aghmat project, which is the first such project to be initiated during an excavation, and to be conducted mainly by a Moroccan team; it aims also to highlight the conservation procedures adopted and to incite discussion.     

Management of Historic Shipwrecks Through a Combination of Significance and Conservation Assessments

Abstract

Corrosion modelling of decay rates of the iron wrecks in Port Phillip Bay, Victoria, has enabled an estimation of the speed at which the historic resource of iron shipwrecks is disappearing. Use of the significance ranking of the iron wrecks, based on the Australian National Standards for significance assessment, provides a useful guide to decision-making, but decisions based solely on these criteria can lead to less than optimal results. From the corrosion rates and the amount of residual metal thickness in structural elements it is possible to determine a conservation ranking that is based on the need for intervention and the chances of being successful in stabilizing the wrecks. The arithmetic product of the significance and conservation rankings defines the treatment score or ranking which forms the basis for rational decision making about deployment of resources.     

Analytical methods for the conservation of the Buddhist temple II of Krasnaya Rechka,Kyrgyzstan

Abstract

The methods employed for selecting the repair material for the Buddhist temple II of Krasnaya Rechka, a site located in the upper Chuy Valley, Kyrgyzstan, are described in this article. The temple is built of mud brick and was excavated during several campaigns between 1938 and 1998 with no provision being made for conservation. The first emergency protective measures were initiated in 2003 during a UNESCO project that included other sites located in the Chuy valley. Most of the eroded walls of the temple were given a temporary shelter coat of mud bricks, a method that has proved effective. The main problem after proving the shelter coat was how to assess the repair material for future conservation work (it is planned to repeat the application of the shelter coat, but with materials with improved performance). Assessment was carried out after extensive laboratory analysis of both historic and repair materials, but also after test wall construction and monitoring. The methods explained here could be of use to conservators working in similar projects in the Middle East or Asia.     

Building survey forms for heterogeneous urban areas in seismically hazardous zones. Application to the historical center of Valparaíso,Chile

ABSTRACT

Building survey is an essential data-collection procedure to feed large-scale seismic vulnerability assessment. The available strategies usually consider survey forms to gather information about the urban buildings. The application of the available survey forms poses important challenges for the case of the heterogeneous urban centers including different structural typologies. This work proposes four specific survey forms for traditional structural typologies constructed with masonry, reinforced concrete, mixed steel-reinforced concrete, and timber. The proposed forms request essential information on the parameters necessary for seismic vulnerability assessment, by evaluating the lateral-load resistant system, regularity, condition of conservation, and existing damages. The survey forms were applied to the study of 111 buildings of the historical center of Valparaíso, Chile. The proposed methodology was complemented with the use of Geographic Information Systems to obtain a complete database with the structural characterization of the most representative typologies for future works of large-scale seismic vulnerability assessment.     

Integrated Investigation,Assessment, Intervention Design,and Implementation as a Model for Conservation Practice

Abstract

The Bibi Jawandi Monument Complex is a site of 15th-century partially collapsed glazed masonry tomb structures located in the ancient city of Uch Sharif, in Pakistan. Conservation of the striking monuments has involved an integrated approach comprising investigations of building materials, structural stability, geotechnical characteristics, as well as management capacity and infrastructural considerations of the site and surrounding city. A primary assessment of the site’s aesthetic, artistic, historical, social, and scientific significance guided the development of interventions and conservation priorities. The holistic approach to the protection of the site, in relation to the surrounding historic town, is one of the first such integrated conservation projects to be undertaken in Pakistan and posed numerous conservation challenges. Work is ongoing and continues, relying on intermittent funding, but the project and site serve as a model in the region for thorough assessment informing conservation decision-making.     

Preservation of Earthen Sites in Remote Areas: the Buddhist Monastery of Ajina Tepa,Tajikistan

Abstract

The Buddhist monastery of Ajina Tepa is one of the most significant in Central Asia as it was fully excavated using up-to-date archaeological methods and was extensively documented. The site is a sophisticated blend of earthen architectural forms, sculptural detail and wall painting decoration, all of which are unique in the area. The site is located in south Tajikistan along the Vahsh valley, about 13 km east from the modern city of Kurgan Tybe.

The aim of the paper is to give an overview of the UNESCO/Japan Trust Fund project 'Preservation of the Buddhist Monastery of Ajina Tepa, Tajikistan (Heritage of the Ancient Silk Roads)'. The paper describes the historical background, the main conservation threats, the analytical work in the selection of repair material, the preparatory work before conservation, the documentation activities, and the conservation work carried out at the site.     

The Byzantine conquest of Crete (961 AD), Prokopios' Vandal War,and the Continuator of the Chronicle of Symeon

Abstract

Historians reconstruct the Byzantine conquest of Crete in 960?961 based largely on the History of Leo the Deacon and two variants of the continuation of the Chronicle of Symeon the Logothete. However, the account in the continuation is modelled closely, in narrative structure, imagery, vocabulary and ideology, on Prokopios' account of the conquest of North Africa by Belisarios in 533?534. This challenges our knowledge of the campaign but sheds interesting new light on the sophisticated use of classical texts that Byzantine ‘chroniclers’ could make.     

Re-visiting the field: Collaborative archaeology as paradigm shift

Abstract

The emphasis of the JFA on field methods resonates strongly with current disciplinary interest in multivocality and participatory research. In this new epistemology of inclusiveness, communities play an active role in the production of archaeological knowledge as well as in the conservation of cultural heritage. From the perspective of archaeologists trained in the U.S. who conduct research in Latin America, we historicize changes in the triadic relationship among archaeologists, contemporary communities, and things of the past. This examination focuses on the evolving social context of archaeological practice. The social milieu within which archaeology is conducted is explored further by reference to a recent survey of archaeologists that elicited comments on grand challenges to archaeology. A few examples of the many forms that an engaged archaeology might take are offered from the Maya region. Although collaborative research poses challenges that emerge as communities entangled with archaeological practice become research partners, we suggest that the enhanced relevance that accompanies this transformation is well worth the effort.     

Some considerations for the reburial of painted lime stucco façdesin the Maya region

Abstract

The conservation of Maya stucco façadesin humid tropical conditions poses significant challenges. Professionals in the region consider that reburial is one of the most easily accomplished and cost-effective conservation options; and reburial of modelled and painted lime plaster façades, in conjunction with the construction of exposed replica façadesoverlying the reburied originals, has been or is being considered as a preservation strategy at a number of sites in the region. This is illustrated by two case studies from Belize and one from Guatemala. However, more research is needed to fully understand the benefits and risks of reburial, and to determine the optimal conditions and techniques specifically suitable for wet tropical climates. The range of issues that must be considered for reburial of stucco façadesin this region include their conservation needs in relation to the susceptibility of ancient materials to climatic conditions, management issues such as visitor and interpretation needs and the problem of looting in the region, the feasibility of solutions in relation to available resources, choice of methods and materials used in interventions, and the impact of reburial on the significance of a site, amongst others.     

Biodiversity and Nature Conservation: Some Common Arguments and Alternative Views

Abstract

The impact of human activities on the environment is perhaps now reaching its greatest level of awareness in human history. There is concern regarding health effects of pollutants generated by industry, climate change related to burning of fossil fuels and effects of anthropogenic activities in terms of promoting the extinction of biological species. Proposals are being put forward at local, national and international levels to preserve biodiversity. It is commonly believed that human activities, if not controlled, will lead to dramatic decreases in the earth's biodiversity. In this report, temporal perspectives of biodiversity (e.g. from palaeontology) are emphasized both as reasons for conservation and as possible errors of reasoning in conservation debates. Questions and novel implications related to an integral view of humans as a part of nature are also presented in the context of related environmental issues.     

Excavations at Houndhill,near Barnsley,Yorkshire

Abstract

A ‘cottage’ weaving industry was established at Houndhill, family seat of the Elmhirsts in Worsbrough, near Barnsley, during the mid-16th century. It ceased early in the 17th century but excavation has shown it was revived under new ownership in the late 18th century. During the 19th century the mill became a general farm store and was totally demolished in the 1930s to permit a garden extension. The excavation was planned to retain any remaining features for conservation as part of the historical interest of the residence.¹     

Protecting a Bloodstained History: Battlefield Conservation in Scotland

Abstract

Scotland's battlefields gained legislative protection in March 2011 with the publication of the Inventory of Scottish Battlefields. The background to the Inventory is explored, with a consideration of how similar issues have been approached in other countries. The paper then goes on to examine the approach taken in the creation of the Inventory, looking at the issues that arose and the solutions adopted.     

THE 20TH-CENTURY REVOLUTION IN TEXTILE MACHINES AND PROCESSES. PART 1: SPINNING AND WEAVING

Abstract

This paper reviews the textile revolution of the mid-20th century, a subject little studied by archaeologists, unlike the developments of the 18th and early 19th centuries. The consequences of this revolution pose new challenges to the industrial archaeologist, since the legacy is not distinctive buildings and urban landscape, but the machinery and fabrics themselves. This is the first instalment of a two-part study, looking at the development of the spinning and weaving in the period 1950–85.     

Issues in Urban Industrial Conservation: The Nottingham Lace Market

Abstract

The preservation of industrial buildings of historic interest is of prime importance to the industrial archaeologist. Yet many of these buildings are to be found within the heart of the great manufacturing cities. How are they to be conserved alongside the built environments within which they were originally set? This article takes the Nottingham Lace Market, which contains some of the finest examples of nineteenth century industrial buildings, and addresses itself to the question of how various public agencies have attempted to make the area economically viable in order to facilitate conservation and preservation work.
