Archaeometric Clearinghouse XXI

Abstract

A repository of archaeometric research collections and records has been established at the Conservation Analytical Laboratory of the Smithsonian Institution. It will not only preserve analyzed artifactual and raw material that has been bequeathed to the Smithsonian Institution, but also maintain computer files of current and past analytical work in a form accessible to archaeologists and archaeometrists. This is a report on the origin and scope of this new enterprise, and a call to the archaeometric community to contribute information and materials to SARCAR.

‘St Peter in Volders’ and related base metal figurines resembling the famous statue in the Vatican Basilica

Abstract

The reappraisal of an old find from Volders near Innsbruck, Austria, prompted new research on a group of base-metal statuettes that are miniature copies of the famous bronze statue of St Peter in the Vatican Basilica in Rome. Their age has been the subject of debate. This paper examined several examples of such statuettes to solve the issue with the help of archaeometric analysis. The analysis of the manufacturing technique and alloy composition provided important clues on the dating of the statuettes and allowed the historical interpretation of the group as a whole.     

Tremper Mound,Hopewell Catlinite,and Pima Technology

Abstract

Archaeologists have long recognized that the Hopewell period was marked by the movement of exotic raw materials and artifacts across the eastern United States. The use of archaeometric techniques to trace the sources of these materials is well established. However, little work has been done on sourcing the pipestone used in Hopewell pipes. In this research we use Portable Infrared Mineral Analyzer (PIMA) technology to identify the presence of Minnesota catlinite as a raw material used for pipes recovered from the Tremper Mound (33SC4) caches in the Scioto Valley of Ohio. A new radiocarbon date places the deposition of these caches between B.C. 50 and A.D. 79. The presence of catlinite pipes in Ohio and in Wisconsin, but rarely in Illinois, suggests the existence of a direct west-to-east route from the catlinite quarries through Wisconsin to Ohio. This movement of catlinite appears to have been a short-term Hopewellian event and the material was not used again until late prehistoric times.

Archaeometric Clearinghouse

Abstract

In the course of compiling a list of taxonomic experts with interests in, and expertise relevant to, archaeology, a number of professional societies and other organizations have been found whose members have these qualifications. One of them, the International Council of Archaeo-Zoologists (I.C.A.Z.) was described in JFA 5 (1978) 361-70, and since all members of I.C.A.Z. are, by definition, concerned with archaeology, the entire membership list was reprinted by permission.

The following sections deal with several groups whose central purpose is not archaeometric, but among whose members are many who have knowledge pertinent to archaeology and who may be interested in scientific-archaeological collaboration.     

Eco-Archaeometry: Interdisciplinary Applications in Egypt

Abstract

One of the problems currently faced by modern society is the worldwide catastrophic deterioration of archaeological and cultural sites directly exposed to the action of the environment. Frequently, it has proved difficult to identify the processes responsible for these deteriorations, which are often the result of an abrupt change in site specific environmental conditions. To understand them a broad interdisciplinary approach is needed, and consequently, a substantial input from several disciplines, such as archaeology and archaeometric, environmental and conservation sciences, is necessary. Such interaction is particularly necessary on a basic research level, and can best be achieved if the relevant disciplines are drawn together a priori on equal footing into a complementary effort in eco-archaeometry. The primary goal of eco-archaeometry is to identify and quantify physicochemical processes which cause the deterioration of ancient cultural patrimony. Its findings are essential prerequisites for the development of optimum, safe methods for conservation and preservation of ancient monuments. Some examples of the eco-archaeometric approach in Egypt are summarised and it is demonstrated that without an interdisciplinary approach such studies would not have been successful.     

Archaeometric Clearinghouse

Abstract

The “Clearinghouse” continues to evolve in ways designed to enhance its original and continuing purpose: to build bridges between archaeology and archaeometry. An earlier instalment contained a state-of-the-art report on “Direct Detection in Radiocarbon Dating” by E. B. Banning and L. A. Pavlish (JFA 5 [1978] 480–483). This is the first time the column carries an account of original research. Such reports are ordinarily found in the main sections of the Journal, but the paper below presents a methodologically novel approach that promises to further the use of archaeometric analysis of large assemblies of archaeological finds.

One of the limits of sophisticated (read expensive and time-consuming) methods of physical or chemical analysis is that they cannot be routinely applied to tens of thousands of objects, and that a mere handful of analyses out of such large bodies of artifacts may not be representative of the whole. The approach used by Ms. Minzoni-Deroche bridges this gap and should encourage field archaeologists and archaeometrists to join forces in tackling large assemblies of finds that have not seemed to be attractive targets before.     

PANTELLERIAN WARE: A COMPREHENSIVE ARCHAEOMETRIC REVIEW*

Pantellerian ware is a Late Roman cooking ware whose production centre was established on the island of Pantelleria by the pioneering research of Fulford and Peacock almost 20 years ago ( Peacock 1982 ; Fulford and Peacock 1984 ). Archaeological and archaeometric studies carried out by the authors of the present contribution during the past four years have aimed to fully characterize this ceramic class. Recurrent ceramic forms, their distribution over time and space, their petrographic characteristics and their chemical identity, as well as possible raw materials and their technological properties, were considered. The present paper is a comprehensive review of this archaeometric work and aims to establish a ‘reference group’. Using a representative number of samples of Pantellerian ware that were recently discovered in the island through archaeological field surveys or surface and submarine excavations, it was possible to characterize in detail the compositional variability of this ware in terms of chemistry and petrography. Furthermore, the physical properties of this ceramic type have been defined in order to better understand its performance characteristics, mainly in response to induced thermal stress. In the meantime, the experimental mixing and tempering of locally sampled raw materials have shed light on the ancient manufacturing process and have led to an approximation of the original paste.     

ARCHAEOMETRY AT SLOWPOKE‐TORONTO

This paper describes the archaeometric research conducted at the SLOWPOKE Reactor Facility of the University of Toronto (SLOWPOKE‐Toronto) during its existence from 1971 to 1998. The contributions to student teaching and research are described, and the total contribution of the facility to studies of an eclectic assortment of ancient and historic materials is addressed.     

A REVIEW OF SUPERVISED AND UNSUPERVISED PATTERN RECOGNITION IN ARCHAEOMETRY*

Principal component, cluster and discriminant analysis are multivariate statistical methods that are widely used in archaeometry. They are examples of what are known in some literatures as unsupervised and supervised learning methods. Over the past 20 years or so, a wide variety of other learning methods have been developed that take advantage of modern computing power and, in some cases, have been designed to handle data sets more complex than those often used in archaeometric data analysis. To date, these methods have had little impact on archaeometry. This paper reviews, in a largely non‐technical manner, the ideas behind these newer methods; illustrates their use on a variety of data sets; and attempts to assess their potential for future archaeometric use.     

ANALYSING THE VINLAND MAP: A CRITICAL REVIEW OF A CRITICAL REVIEW*

In an attempt to validate the Vinland Map as a genuine15th century work, Garman Harbottle (2008 ) claims to review critically, and thereby discredit, the archaeometric research undertaken on the Map's ink by Walter McCrone (1974–1999) and Brown and Clark (2002 ). In this paper we outline and discuss the numerous arguments that are presented by Harbottle, all of which we find to be misleading or at best highly questionable.     

Microchemical and crystallographic analysis of human bones from Nasca,Peru. A possible method of direct dating of archaeological skeletal material

This paper provides two archaeometric equations obtained by crystal–chemical parameters for dating human bone samples from the archaeological site of Nasca, Peru. Based on radiocarbon dating, the burials span from 500 BC to AD 1000. Crystal–chemical modifications in bone hydroxylapatite over time were compared with a twentieth century skeleton from Italy. Chemical analysis was carried out by means of electron microprobe along a profile from the periosteal to the endosteal border of the midshaft of four human femurs. The results indicate that the Ca/P ratio is linearly correlated with time according to the equation t=7880.68Ca/P−12805.90 (r=0.97; r²=0.95). Bone apatite X-ray powder diffraction analysis showed a systematic increase in the (002) reflection intensity with time, according to the equation t=250.49h/a−1961.86 (r=0.98; r²=0.97). The two independent archaeometric equations permit good accuracy in dating osteoarchaeological remains from the south coast area of Peru. © 1998 John Wiley & Sons, Ltd.     

Environmental adjustment and private economic strategies in reindeer pastoralism: Combining game theory with participatory action research

The aim of this article is to suggest a research approach to be used in studies of common‐pool resource problems and the deterioration of reindeer pasture. A frequent strategy in such studies is game theory based on rational choice assumptions. This approach has been criticised, for instance, for the neglect of local knowledge concerning cultural preconditions and for the political implications damaging Saami reindeer‐ecology. Our contention is that such problems can be handled by combining game theory with participatory action research when studying the subject above.     

OBSIDIAN IN THE MEDITERRANEAN AND THE NEAR EAST: A PROVENANCING SUCCESS STORY

Obsidian provenancing studies comprise one of the most productive and successful research programmes of archaeological science. Obsidian characterization has been successful because workable obsidian is homogeneous on a small scale, analysable by a large number of methods, and is restricted to a small number of mainly readily distinguishable geological sources. Analytical, dating, source, and trade studies within the western Mediterranean, central and eastern Europe, the Aegean, and Anatolia and the Near East during the last 30 years or so are reviewed. Research has shown that distributions are mainly separate in the four regions examined, and that obsidian was traded up to 900km in the prehistoric period. Publications on obsidian in the areas under review reached a peak of frequency in the later 1970s and 1980s, but have now decreased in number. This may reflect changing fashions in archaeometric studies, and a current lack of routine application of the provenancing methods developed.     

‘M GLOW BLUE’: ARCHAEOMETRIC RESEARCH AT MICHIGAN'S FORD NUCLEAR REACTOR

The Ford Nuclear Reactor operated from 1957 to 2003 on the University of Michigan's North Campus in Ann Arbor, Michigan. Over its 45‐year lifespan, the facility played a key role in archaeometric research, fostering early methodological studies using INAA and supporting archaeological materials science investigations of lithics, ceramics, metals and bone. One small part of the FNR's abundant legacy was the initiation of trace‐element studies of Oaxacan ceramics, which are now beginning to shed light on early exchange interactions and the origin of the Monte Albán state in the Valley of Oaxaca, Mexico, between 500 bce and 200 ce .     

COINS,ARTEFACTS AND ISOTOPES—ARCHAEOMETALLURGY AND ARCHAEOMETRY*

Archaeometallurgy is one of the earliest manifestations of archaeometric research, using science‐based approaches to address cultural–historical questions. This review first outlines the extent of the field, defining in some detail the main branches of archaeometallurgy, and their specific methodological approaches. It then looks at some of the early publications pioneering archaeometallurgical research, to set the scene for the publication pattern of archaeometallurgy in general, and the role that Archaeometry played in publishing archaeometallurgical research. The analysis of archaeometallurgy‐themed publications in Archaeometry, their change over time and their relationship to the total range of work done in the field indicates that there is a rather narrowly defined and specific type of archaeometallurgy that gets published in Archaeometry, initially with a strong focus on coin and object analysis, often combined with method developments. The more recent developments in isotope‐based studies in archaeometallurgy find only a limited representation in the journal, despite the leading role that the Isotrace Laboratory played in this discipline, for some considerable length of time. More recently, this Archaeometry‐specific ‘flavour’ of archaeometallurgy seems to weaken, with an increase of papers on iron and on primary production in general, subjects still much under‐represented.     

Changing Ethnic Segregation and Housing Disadvantage in Dundee

Abstract

Dundee has a small black and minority ethnic (BME) population, which has been neglected by previous research, as have BME populations in small towns and cities generally. As in other British cities, the residential locations of the main BME groups are distinct from that of the white population. After briefly reviewing the history of settlement in Dundee, this paper examines the extent to which patterns of ethnic segregation have changed between 1991 and 2001. Some moves towards dispersal and suburbanisation are identified but there are important contrasts between different BME groups. The implications of segregation for housing availability are assessed through Census of Population data. The hypothesis is posed that the consequences of segregation for housing disadvantage are greater in small cities such as Dundee.     

Some Ideas and Reflections on Teaching 'Ideas' in Geography

This paper outlines the characteristics of a seminar on realism which forms part of the teaching of 'ideas and methods in geography' in the department concerned. The seminar requires each of about a dozen students to answer a specific question by reading a single paper, writing a summary answer to the question based on this source, and delivering an oral presentation. The questions are structured to deal with abstract theoretical issues at first, and then to consider the implications of these issues for research practice. The experience of the seminar is intended to help students prepare for an open-book examination, and to develop the research planning for their dissertations. Student feedback is reviewed, and ideas for modification of the seminar structure are discussed.
