Archaeology and Authenticity in South African Heritage Locales and Public Spaces

Abstract

This article investigates the construction, display and consumption of archaeological authenticity at two museums and two heritage-themed entertainment locales in South Africa. I consider authenticity not simply as intrinsic, but as strongly framed by physical and conceptual locations, before audience experiences and post-colonial priorities. I use as case studies the Maropeng visitor centre at the Cradle of Humankind, the Origins Centre Museum at the University of the Witwatersrand, Sun City's Lost City, and the Monte Casino entertainment complex in northern Johannesburg.     

Casting Identity in the Cultural Tourism Industry: Greek Tourist Guides in a 'Mission' of Heritage Interpretation

Abstract

The focus of this article is on how identity on a local level is expressed through cultural heritage interpretation and negotiated in an environment of globalization, but also multiculturalism and promotion of locality, like the European Union (EU). Interpretation is public communication of perceptions and values attached to heritage, and a main component of cultural tourism. Tourist guides in Greece, where guiding is strictly regulated, have been confronted with the EU on several occasions. Through the examination of this conflict, issues such as rights of interpretation, the projected image and identity of place and people, otherness and identity realization, the role of education and especially archaeology in governing, as perceived by the Greek tourist guides, are examined and analysed in the contexts of audience, state and the EU.     

Digging Franco's Trenches: An Archaeological Investigation of a Nationalist Position from the Spanish Civil War

Abstract

As part of a project on the archaeology of the civil war and dictatorship in Spain, a Nationalist position was excavated in the village of Abánades (Guadalajara), which was occupied between March 1937 and the end of the war. The sector that was excavated comprised a trench, two dugouts, and a stone-and-concrete covered trench. The findings reveal more about daily life in General Franco's trenches, while they also offer insights into totalitarian ideology, international involvement in the conflict, and the war economy.     

Isolation and Isotopic Analysis of Individual Amino Acids from Archaeological Bone Collagen: A New Method Using Rp‐hplc

This paper presents a new method for the isolation and isotopic analysis of some individual amino acids from proteins. The technique and its constituent steps are discussed; then isotopic analyses of amino acids from several samples of bone collagen from the Late Roman site of Poundbury, Dorset, UK are presented. The applications of the method are discussed, as well as some advantages of this technique relative to other methods. Although developed for use with archaeological bone collagen, the technique is equally applicable to other proteinaceous materials. The use of reversed‐phase HPLC avoids problems of isotopic fractionation inherent in using ion‐exchange HPLC. Amino acids are isolated preparatively, allowing both carbon and nitrogen isotopic values to be measured on a single sample using CF‐IRMS. Since amino acids are isotopically analysed in an underivatized form (unlike GC‐C‐IRMS), the method also presents the possibility of collecting the CO₂ generated during CF‐IRMS: this would allow the subsequent dating by ¹⁴C‐AMS of individual amino acids isolated from archaeological samples.     

EVALUATION OF ARCHAEOLOGICAL LAYERS AIDED BY SPECTROMETRY AND ROBOTICS*

All archaeologists have faced the problem of interpreting stratigraphy. While this task can sometimes be very clear and unambiguous, this is far from always being the case. Because human beings are limited in their appreciation of soil by subjectivity and by the ability of their senses, it can be useful to turn to technology for help. Here, we present our research on the characterization of archaeological soils by spectrometric analyses, and we demonstrate the perspectives offered by robotics to excavate in fieldwork and to record the stiffness of the earth.     

IDENTIFYING AND CLASSIFYING VEIN QUARTZ ARTEFACTS: AN EXPERIMENT CONDUCTED AT THE WORLD ARCHAEOLOGICAL CONGRESS, 2008

Worldwide, vein quartz was used as a raw material for stone tools, and in many regions quartz was the dominant raw material, if not the only raw material. While using quartz was not necessarily problematic for the communities in question, and was often preferred over other materials, the ‘problem’ with quartz is for archaeologists attempting to analyse the material, especially with coarse‐grained quartz. This paper presents the results of a quartz recognition experiment conducted on volunteer participants at the 2008 World Archaeological Congress (WAC) conference held in Dublin, Ireland. The results have shown that the identification and classification of vein quartz artefacts is particularly challenging, even for analysts with substantial experience in quartz artefact analysis.     

COMPUTER VISION‐BASED ORTHOPHOTO MAPPING OF COMPLEX ARCHAEOLOGICAL SITES: THE ANCIENT QUARRY OF PITARANHA (PORTUGAL–SPAIN)

Ancient quarries are intriguing archaeological sites, but their detailed recording is complex. This paper presents a cost‐effective approach to mapping of the Roman quarry site of Pitaranha (Portugal–Spain). First, aerial photographs were acquired using a radio‐controlled digital reflex camera attached to a Helikite, which allowed the acquisition of the necessary low‐altitude aerial footage in the very unstable wind conditions above the quarry. Using computer vision algorithms, the resulting set of photographs was semi‐automatically transformed into a Digital Surface Model (DSM) and a corresponding orthophotograph. Besides focusing on the acquisition and processing method, this paper evaluates the accuracy of the generated products. The orthophotograph proved to be satisfactorily accurate for 1:200 hard‐copy mapping.     

X‐RAY SUB‐MICRON TOMOGRAPHY AS A TOOL FOR THE STUDY OF ARCHAEOLOGICAL WOOD PRESERVED THROUGH THE CORROSION OF METAL OBJECTS

Wood preserved in the corrosion layer of two early medieval iron objects was examined using X‐ray tomography. A state‐of‐the art multi‐resolution X‐ray tomography set‐up ( http://www.ugct.ugent.be ) provided virtual cross‐sections of the archaeological wood samples at sub‐micron resolution. These were compared with scans of samples of similar modern wood. These scans demonstrate the power of sub‐micron X‐ray tomography for wood identification, although the process of mineralization pushes this technique to its limits. Furthermore, this technique facilitated appraisal of the mineral content of the archaeological wood, which is useful in selecting the most appropriate strategy for the (preventative) conservation of the archaeological object.
