Interpreting the past: Presenting archaeological sites to the public

Abstract

A wide range of methodologies have been applied to promote the conservation of exposed and managed archaeological sites, including shelters. Commonly used as a protective measure in many areas of the world, shelters are not as common in the USA. In addition there have been few efforts to evaluate scientifically their use and efficacy. As a response to the recognized need to further scholarship and dialogue about shelters, a colloquium on the topic was held in Tumacacori, Arizona, in January 2001. The colloquium goals focused on research, exchange of information, the advancement of methodological approaches, incorporation of sheltering concepts into planning processes and identifying field needs. To achieve these aims, the following four themes were developed:

? deciding to shelter

? establishing conservation, design and construction criteria

? designing and constructing shelters

? evaluating shelter performance.

The colloquium followed a course of presentations, site visits and a final plenary session summing up the issues put forth. Participants represented a cross-section of disciplines and a range of international experiences.     

Privatising the public past: The economics of archaeological heritage management

Resumen Los yacimientos prehispánicos de Ca?ada de la Virgen y Teotihuacán, en Méjico, se hayan en el centro de una contienda que mantienen actualmente la arqueología pública, el estado y los intereses privados. Las leyes que protegen el patrimonio cultural de México están siendo pasadas por alto por las políticas de privatización que imponen un valor económico a los yacimientos arqueológicos argumentando que deben aportar un beneficio económico. Las obligaciones de los gobiernos nacionales hacia los yacimientos arqueológicos están siendo socavadas a medida que aumenta el riesgo de privatización de los yacimientos. El público se halla cada vez más desamparado cuando el gobierno, que custodia el patrimonio arqueológico, pone el pasado a la venta. Como evidencian los conflictos de Ca?ada de la Virgen y Teotihuacán estos temas van más allá de lo local, ya que afectan a la globalidad. Los arqueólogos, responsables de proteger el pasado, deben desarrollar una estrategia para frenar esta tendencia, basándose en un mensaje claramente articulado que transmita la urgencia de la crisis que amenaza a los yacimientos arqueológicos.

Résumé Les sites pré-hispaniques du Ca?ada de la Virgen et Teotihuacán au Mexique sont au centre d'une lutte continuelle entre l'archéologie publique, l'état et les intérêts privés. Les lois protégeant l'héritage culturel du Mexique sont détournées par des programmes de privatisation qui imposent une valeur économique sur les sites archéologiques, avec pour but de réaliser un profit financier. Les devoirs des gouvernements envers les sites archéologiques sont sapés alors que les sites sont de plus en plus en plus abandonnés aux aléas des développeurs privés. Le public perd ses droits de concession lorsque les gouvernements, agissant en tant que gardiens du patrimoine culturel permenttent la vente du passé. Les conflits du Ca?ada de la Virgen et Teotihuacán démontrent bien que ces problèmes vont au-delà de la communauté locale à la communauté mondiale. Les archéologues à qui il est donné de protéger le passé doivent développer une stratégie pour aller à l'encontre de ces tendances, stratégie basée sur un message clair portant sur l'urgence de la crise qui menace les sites archéologiques. De nos jours, les sites archéologiques encourent de plus en plus de risques aux mains des gouvernments. Les programmes économiques de privatisation menacent la perte des droits du public sur son propre passé. Ce passé est un capital symbolique pour le public. Pourtant, c'est le gouvernement qui profite de l'échange de ce capital symbolique contre un capital économique. Cettecommunication illustre deux études récentes émanant du Mexique où ont lieu de tels échanges. L'étude de ces cas se termine par un appel aux archéologues pour travailler plus activement avec le peuple en vue de protéger le passé. *** DIRECT SUPPORT *** A00U1004 00005

     

The impossibility of resurrecting the past: Reconstructions on archaeological excavation sites

Abstract

Since the beginnings of archaeological research, scientists have attempted to explain the past to a larger public. In the nineteenth century the quality of reconstruction drawings by architects was high but, after excavations were finished, the sites were left as they were, without conservation, while the movable finds were exhibited in the great museums of the European capitals. Today's mass tourism, however, demands attractions at the original ancient sites. The tourist industry, which brings by far the largest pool of visitors to the sites, sets the standards, but its interests centre on quick and simple ‘consumption’ of impressive ruins. Different methods have been employed in creating tourist attractions – from reconstructing ancient buildings to having museum staff in costume demonstrate elements of daily life in history. But it is the ruins on excavation sites, even in their damaged state, that are the irreplaceable, authentic records of the past. Archaeological preservation, therefore, has to mean uncompromising conservation of the damaged original remains. They should not be sacrificed for the sake of questionable ‘progress’ or popularization.     

Flights into the past: full-waveform airborne laser scanning data for archaeological investigation

Airborne Light Detection and Ranging (LiDAR) is a quite recent (mid-1990s) remote sensing technique used to measure terrain elevation. Recent studies have examined the possibility of using LiDAR in archaeological investigations to map and characterize earthworks, to capture features that may be indistinguishable on the ground and to aid the planning of archaeological excavation campaigns.     

Palynology and archaeological inference: bridging the gap between pollen washes and past behavior

Credible interpretation of pollen recovered from archaeological sites hinges upon understanding how pollen becomes deposited by both the environment and human behavior. The environmental role has been studied to some extent, but how the activities of people have formed the pollen assemblages at archaeological sites is usually just assumed rather than considered explicitly. Moreover, the complexity involved in the interaction between human behavior and pollen ecology is seldom considered. An archaeological case study of grinding tool pollen washes highlights the ambiguities of standard practice because the results confound common assumptions about pollen washes. A series of experimental seed and grinding tool washes designed to test the relationships between the processing of seeds and the deposition of pollen help explain why, for most situations, artifact pollen washes do not provide direct or even faithful records of plant processing. These results highlight the need for further experimental research with pollen so that we are warranted in making behavioral inferences from palynology. This conclusion is easily extended to other microbotanical data classes that archaeologists regularly employ.     

Condition reporting and monitoring of archaeological sites: The use of large-scale vertical aerial photographs in New Zealand

Abstract

Large-scale aerial photographs (approximately 1:2000 to 1:10000 scale on the negative) have a number of virtues for condition reporting. The same site can be photographed at intervals so that rate of change can be measured. The record is objective and it gives sufficient detail to observe not only patterns but also the details of condition in such matters as past repairs, sheep tracking or the existence and state of repair of fences. In addition, photographic prints provide a ready basis for annotation. They are the primary record of condition and may highlight and focus the needs for conservation intervention. Archiving of photographs makes possible future study in the light of new research interests. Monitoring using photographs taken at regular intervals is also recommended.     

Mapping by matching: a computer vision-based approach to fast and accurate georeferencing of archaeological aerial photographs

To date, aerial archaeologists generally apply simple rectification procedures or more expensive and time-consuming orthorectification algorithms to correct their aerial photographs in varying degrees for geometrical deformations induced by the topographical relief, the tilt of the camera axis and the distortion of the optics. Irrespective of the method applied, the georeferencing of the images is commonly determined with ground control points, whose measurement and identification is a time-consuming operation and often limits certain images from being accurately georeferenced. Moreover, specialised software, certain photogrammetric skills, and experience are required. Thanks to the recent advances in the fields of computer vision and photogrammetry as well as the improvements in processing power, it is currently possible to generate orthophotos of large, almost randomly collected aerial photographs in a straightforward and nearly automatic way. This paper presents a computer vision-based approach that is complemented by proven photogrammetric principles to generate orthophotos from a range of uncalibrated oblique and vertical aerial frame images. In a first phase, the method uses algorithms that automatically compute the viewpoint of each photograph as well as a sparse 3D geometric representation of the scene that is imaged. Afterwards, dense reconstruction algorithms are applied to yield a three-dimensional surface model. After georeferencing this model, it can be used to create any kind of orthophoto out of the initial aerial views. To prove the benefits of this approach in comparison to the most common ways of georeferencing aerial imagery, several archaeological case studies are presented. Not only will they showcase the easy workflow and accuracy of the results, but they will also prove that this approach moves beyond current restrictions due to its applicability to datasets that were previously thought to be unsuited for convenient georeferencing.

ZooMS: making eggshell visible in the archaeological record

Avian eggshell is a common component of many archaeological deposits, but its archaeological potential remains largely unexplored. The most obvious reasons are two-fold. Firstly, despite its abundance on many sites, eggshell is often overlooked during excavation. Even when it is recovered, small fragmented remains are difficult to identify taxonomically. Here we introduce a minimally destructive qualitative analytical technique for taxonomic identification of eggshell fragments based on highly sensitive mass spectrometry and peptide mass fingerprinting (ZooMS), and illustrate its application to eggshell recovered from the Viking Age urban site at Hungate, York. We adopt a more extreme version of the method of bleach treating used to prepare ancient eggshell for DNA analysis, followed by conventional peptide mass fingerprinting using MALDI-ToF mass spectrometry. The development of this technique will allow future research to make better use of eggshell fragments recovered from archaeological sites.     

Investigation of past archaeological landscapes using remote sensing and GIS: a multi-method case study from Mount Ida,Crete

Spatial analysis in geoarchaeological applications can be improved by implementing a wider set of geoecological parameters, in order to provide more precise results. The aim of the paper is to show how geoscientific ground-truth and techniques can be adopted for detailed archaeological studies using a comprehensive set of environmental variables that might have influenced ancient settlement patterns. The project focuses on spatial patterns of archaeological sites as well as Bronze Age communication paths in Central Crete by applying a multi-method approach (surveying, remote sensing, DEM analysis, least-cost analysis, candidate site detection, predictive modelling, etc.). In contrast to conventional archaeological GIS applications this enhanced strategy offers promising prospects regarding landscape and settlement modelling.     

Multiple osteochondromas in the archaeological record: a global review

Multiple osteochondromas is an inherited autosomal dominant condition of enchondral bone growth. The paper undertakes the first synthesis study of the 16 known cases of the condition that have been identified in the international palaeopathological record. It also includes information derived from two newly discovered cases of the disease in two adult male individuals recovered from the Medieval cemetery at Ballyhanna, Co. Donegal, Ireland. The formation of multiple osteochondromas is the best known characteristic of the disease but it also involves the development of a suite of orthopaedic deformities. These deformities, which include disproportionate short stature, inequality of bone length, forearm deformities, tibiofibular diastasis, coxa valga of the hip and valgus deformity of the knee and ankle, are discussed in relation to the archaeological cases. Numerous synonyms for the disease have been used within the various publications produced by palaeopathologists, and this can generate confusion among readers. As such, the paper recommends that in future palaeopathologists should follow the guidance of the World Health Organization and use the term multiple osteochondromas when discussing the disease.     

Debating Belarus: A Framing Comment

A British political scientist and eminent specialist on the politics of the post-Soviet states comments on the divergent perspectives offered in the two preceding papers in the symposium on Belarus in the same issue of Eurasian Geography and Economics. He first briefly reviews the diverse approaches to the study of Belarus evident in the academic literature, and the reasons scholars might be led to the country as a topic of study, especially its suitability as a test bed for several issues of importance in comparative studies (e.g., the nature of presidential power and of political "charisma," of governance without political parties, and an economic model that has appeared until now to have resisted the path of accelerated market reform). Probing more deeply, the author identifies issues of the comparative method of particular relevance to the exchange that warrant further investigation, and goes on to present his own survey data (from early 2011 for Belarus and from 2010 in Ukraine and Russia) in an effort to advance the debate on these issues. In concluding, he suggests a line of further enquiry for understanding better the seeming paradox that is Belarus—the role played by retention of "Soviet" institutions (e.g., trade unions, local councils) that offer a means of communication between ordinary citizens and the authorities.     

European Union at the Crossroads: A Framing Comment

In a framing comment embracing the preceding four papers devoted to the enlargement of the European Union in 2004, a prominent American geographer reviews some of the major problems confronting the European continent. The paper, which begins with the author's view of Europe's dilemma in late 2006, covers a number of geographic implications of the May 2004 expansion. Noted are Russia's overland access to Kaliningrad, the addition of ca. 8 million underprivileged Roma (presently the Union's largest minority population), the potentially divisive new boundary with Russia, the future candidate states emerging from the former Yugoslavia, the prospects of Ukraine's possible membership, and the challenge of Turkey's quest for admission to the EU.

Conflicts in the Caucasus and Their Resolution: A Framing Essay

An essay by an experienced scholar-practitioner of conflict resolution in the Caucasus examines the narratives of the interlocking conflicts involving Georgia. The author argues that more complex narratives are necessary for forging constructive paths toward conflict resolution. After outlining the stereotypical arguments presented by the different sides, the author urges a multi-track diplomacy that creates opportunities for the development of more complex narratives. Research, whether by conflict insiders or by external investigators, is presented as a potential contributor to the larger peace processes. In addition to comments on the three preceding articles in the symposium published in Eurasian Geography and Economics, the paper highlights the utility in understanding local context and complexities in order to create more inclusive and complex narratives that can support confidence-building activities and eventual progress on outstanding issues plaguing the conflict-affected populations in the region.
