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.     

DATING THE AEGEAN LATE BRONZE AGE WITH RADIOCARBON: ADDENDUM

Additional comment on the new high-precision calibration curves and tables published after this article (Archaeometry 29 (1), 1987, 45–49) was in press.     

ARCHAEOMAGNETISM IN ARCHAEOMETRY— A SEMI‐CENTENNIAL REVIEW*

The journal Archaeometry and its first co‐editor Martin Aitken played key roles in the development of archaeomagnetism. This paper briefly reviews all papers published in Archaeometry, and a few others, dealing with archaeomagnetic secular variation, archaeomagnetic dating, archaeointensity studies and related applications of magnetic studies to archaeology, to indicate some of the major developments over the past 50 years.     

RADIOCARBON DATES FROM THE OXFORD AMS SYSTEM: ARCHAEOMETRY DATELIST 2

In an effort to make measurements readily available as soon as possible, dates from the Oxford Radiocarbon Accelerator will now be published regularly in Archaeometry. These datelists will not be a substitute for final publication in Radiocarbon, which is desirable for all dates, but are intended to serve as a formal interim publication of dates, so that they can be cited.     

ARCHAEOMETRY AND MUSEUMS: FIFTY YEARS OF CURIOSITY AND WONDER*

Artefacts and works of art kept in museum collections originated in many cases from ancient private collections. In such cases, a partial or total absence of historical information may create additional problems concerning their authenticity. The study of museum collections and their preservation requires the use of analytical techniques but also combined examination techniques not commonly necessary for the study of archaeological objects. This paper gives an overview of the importance of museum items for the understanding of the past, the difficulties relating to their authentication and the significant advances brought about by science‐based techniques, in particular those cases discussed in Archaeometry during the past 50 years.     

COPPER AND COPPER ALLOYS IN ANCIENT TURKEY: SOME NEW ANALYSES

This note presents some new analyses for 13 early copper and bronze artefacts from Turkey in the Collection of the Ashmolean Museum, Oxford. They were not included in a small programme of early copper and bronze objects from Iraq, Syria and Palestine (Moorey and Schweizer 1972, Archaeometry 14 (2), 177–198) and conclude this pilot-project.     

Spartan dependence on Laurion lead

This article presents contextual evidence for the interpretation of lead isotope analysis (LIA) of artefacts from the Archaic Greek Mediterranean. In particular, I make a response to Wood’s suggestion in Archaeometry (2022, first view, ‘Other ways to examine the finances behind the birth of Classical Greece’) that the end of the production of lead votive figurines in Sparta might have been caused by Athenian restrictions to Laurion lead exports, drawing on new LIA of the Spartan lead votives and wider considerations concerning the trade, cost and volume of lead in the 7th to 5th century bce Mediterranean.     

DETECTING TRENDS IN THE PREDICTION OF THE BURIED PAST: A REVIEW OF GEOPHYSICAL TECHNIQUES IN ARCHAEOLOGY*

Geophysical survey techniques are a highly visible part of the scientific toolkit that is now used by archaeologists. In this paper, the history of the use of geophysical techniques in archaeology will be discussed, as will significant research themes associated with the most widely used prospecting devices. It is apparent that while the use of geophysical techniques is at an all‐time high, there are many key areas where prospecting is rapidly developing. Some of the advances relate to fundamental aspects of the techniques, while others dictate how we undertake survey in the future. There is a movement away from pre‐gridded survey areas towards real‐time GPS for navigation. This allows greater integration, or fusion, of disparate data sources using visualization techniques derived from associated disciplines. The analysis of landscapes has become a major component of the application of new technology and there are many challenges to be tackled, including how to analyse and interpret significant archaeology within large‐scale, data‐rich, multi‐technique investigations. The reflective nature of the review acknowledges the important role of Archaeometry in the development of archaeological geophysics.     

Identifying stone tools used in mining,smelting, and casting in Middle Bronze Age Cyprus

Abstract

Metallurgical production sites are often difficult to identify in the archaeological record because ore beneficiation and slag processing in the past involved the use of ground stone tools that were similar to those used in other contexts to prepare cereals and foods. Analysis of the ground stone assemblage from a Middle Bronze Age copper mining and production site at Ambelikou Aletri in Cyprus provided an opportunity to distinguish industrial and domestic ground stone tools and to identify the types of tools used in different stages of metal production. A comparison of tool morphologies, raw materials, and wear and breakage patterns from Ambelikou Aletri with those from contemporary domestic contexts, suggests that distinctions in the nature and structure of industrial and domestic tool kits do exist and those distinctions have an important role to play in identifying mining, smelting, and casting sites in the future.     

Archaeometric analysis of the ‘greco scritto’ marble slabs from the Edificio dei Triclinii at Murecine (Pompeii,Italy)

This paper presents the results of the archaeometric analysis of the greco scritto marble slabs from the Edificio dei Triclinii, an inn or statio negotiatorum discovered at Murecine in Pompeii’s suburbs in 1999–2000. A total of 14 samples were collected and subjected to standard X-ray diffraction (XRD), optical microscopy (OM) on thin sections and stable isotope ratio analysis (SIRA) to assess the stone’s identity and provenance. The results of this study substantiate the hypothesis (already put forward and based on a macroscopic identification by Perna and Scognamiglio) that the stone originates from the Hasançavuşlar quarries near Ephesus in Asia Minor, and represent the first step towards a systematic contextual and geochemical study of Ephesian greco scritto in Roman contexts and its respective contribution to the Roman stone trade.     

COLD NEUTRON PROMPT GAMMA ACTIVATION ANALYSIS—A NON‐DESTRUCTIVE METHOD FOR CHARACTERIZATION OF HIGH SILICA CONTENT CHIPPED STONE TOOLS AND RAW MATERIALS*

Recently, several archaeometrical projects have been started on the prehistoric collection of the Hungarian National Museum. Among the analytical methods applied, non‐destructive prompt gamma activation analysis has a special importance. We have also tested the potential of this method on chipped stone tools, with the aim of determining their exact provenance. On the basis of major and trace element components, characterizations of stone tools and their raw materials—silicites (flint, chert, radiolarite and hornstone) as well as volcanites (felsitic porphyry and obsidian)—were performed. We discuss some important results concerning each group, as case studies. Compiling the data set of different PGAA analysis series, compositions of 110 samples are reported, including 76 archaeological pieces. In the future, we plan to extend the number of investigated objects in each class.     

The Epipaleolithic (Iberomaurusian) from Grotte des Contrebandiers,Morocco

First identified 100 years ago, the Iberomaurusian is an Epipaleolithic industry that was described from a number of sites across western North Africa. One of these is Grotte des Contrebandiers (Smugglers’ Cave) in Morocco, where Abbé Jean Roche recovered Iberomaurusian materials in excavations in the late 1950s. Although the lithics were published in the early 1960s, subsequent changes in methods and in assessing the interpretive potential of lithic assemblages necessitated a restudy of these collections from Contrebandiers. This study led to a better understanding of the lithic types present and of the use of particular stone raw materials. Iberomaurusians emphasized lithic strategies that maximized use of fine-grained stone to the extent that pièces esquillées should be, among others, a defining criterion for this lithic industry.     

DNA AND PROTEIN RECOVERY FROM WASHED EXPERIMENTAL STONE TOOLS*

Traces of protein and DNA are preserved on stone tools used to process animals. Previous research documents the identification of protein residues from tools sonicated in 5% ammonium hydroxide, but it remains untested whether the same treatment yields useable DNA. In this study we report both DNA and protein recovery using 5% ammonium hydroxide from residues on stone tools. We extracted 13‐year‐old residues from experimentally manufactured stone tools used to butcher a single animal. We also show that surface washing procedures typically used to curate stone tools remove only a small fraction of the DNA and protein deposited during animal butchery.     

Evaluation of Fe isotope values as a provenance tool for chert artefacts from the north-eastern United States

Iron (Fe) isotope compositions of prehistoric stone tools and geological sources were compared to evaluate the robustness of this isotopic fingerprinting technique. Artefacts and source materials were collected from the Hatch site in central Pennsylvania, United States, where both veined chert (Bald Eagle chert) and stone tools coexist within several metres. Yellow artefacts (δ⁵⁶Fe = 0.38 ± 0.1, n = 7) and source materials (δ⁵⁶Fe = 0.42 ± 0.1, n = 8) isotopically matched within error. The source values also overlap yellow chert samples from three other Bald Eagle chert locations in the area. These values are different from six other chert locations in the north-eastern United States. These data suggest that the Fe isotope composition of chert artefacts reflect distinct geological sources. To enhance the mechanical characteristics of the stone tools, the chert experienced heat treatment, which induced a phase shift of the Fe oxide mineral goethite to hematite. This phase shift changes the colour of the chert to red. The red chert artefacts and source material also have overlapping Fe isotope values, but are 0.2‰ higher than the initial yellow chert. Experimental work where cherts were heated with different clays shows that Fe exchange with site soils induces the +0.2 fractionation. These data demonstrate that predictable Fe isotope fractionation occurs during heating, resulting in isotopically distinct artefacts.     

BUILDING MATERIALS OF THE THEATRE OF MARCELLUS,ROME*

The building materials of the Theatre of Marcellus, 44–11 bce , reflect Roman builders' careful selections of tuff and travertine for dimension stone and volcanic aggregates for pozzolanic concretes. The vitric–lithic–crystal Tufo Lionato tuff dimension stone contains a high proportion of lava lithic fragments, which increase its compressive strength and decrease water sorption, enhancing durability. Sophisticated installations of travertine dimension stone reinforce the tuff masonry, which is integrated with durable concrete walls and barrel vaults. The pozzolanic mortars of the concretes contain harenae fossiciae mainly from the intermediate alteration facies of the mid‐Pleistocene, scoriaceous Pozzolane Rosse pyroclastic flow. They have pervasive interpenetrating pozzolanic cements, including strätlingite, similar to high‐quality, imperial era mortars. Concrete walls are faced with refined Tufo Lionato opus reticulatum and tufelli, and opus testaceum of fired, greyish‐yellow brick. The exploratory concrete masonry, which includes some of the earliest examples of brick facings and strätlingite cements in Rome, and the integration of these materials in complex architectural elements and internal spaces, reflect the highly skilled workmanship, rigorous work‐site management and technical supervision of Roman builders trained in republican era methods and materials.     

QUANTIFICATION AND DISCRIMINATION OF LITHIC USE‐WEAR: SURFACE PROFILE MEASUREMENTS AND LENGTH‐SCALE FRACTAL ANALYSIS*

This experimental programme employs length‐scale analysis of measured profiles to quantitatively discriminate the surface textures of stone flakes manufactured from East Anglian chalk flint used on four contact materials (shell, wood, dry hide and soaked antler). It presents a method for evaluating texture characterization parameters based on their ability to discriminate wear types, and to determine a level of confidence to the discrimination, using the F‐test. The results of this experimental work demonstrate that relative lengths, over certain scale ranges, can discriminate the stone tool surface wear profiles produced by the different contact materials.     

Special Studies: The Pre-Chavín Stone Sculpture of Casma and Pacopampa

Abstract

In a recent article, “Early Carving From Pampa de las Llamas-Moxeke, Casma Valley, Peru,” Thomas Pozorski and Shelia Pozorski (Journal of Field Archaeology 15 [1988] 114–119) describe an important stone sculpture discovered in their 1987 excavations of Huaca A at Pampa de las Llamas-Moxeke, Casma Valley, Peru. They argued that it was the oldest securely-dated sculpture in Peru based on a radiocarbon date of 1565 b.c. (unrecalibrated), and deemed it unique on the basis of comparisons with the corpus of early stone sculptures from Peru. The dual purpose of this short contribution is to: 1) suggest that on the basis of radiocarbon measurements available it cannot be demonstrated that the Huaca A sculpture is older than the hundreds of stone sculptures from Cerro Sechin in Casma; and 2) draw attention to some intriguing similarities between the Huaca A sculpture and a stone carving from Pacopampa in the Chotano Valley of the Peruvian highlands. These two points highlight the inadequacy of our understanding of the origins of stone sculpture in Peru.     

The Problem of the Missing Harbour of Evagoras at Salamis,Cyprus: a review of the evidence and pointers to a solution

This article summarises the archaeological evidence for the existence of Evagoras' naval harbour at Salamis in North Cyprus, which ancient texts credit him with building c.410–400 BC. Based on a critical examination of previous surveys and his own on‐site observations, the author concludes there is indicative evidence of a constructed harbour c.800 m long, which was divided into two basins by a stone jetty, separated from the city by a stone wall and with some evidence of ship‐sheds at its north end. © 2012 The Author     

The beads of Indian Knoll

ABSTRACT

Busycon discs, barrels, rings, and columellas, Leptoxis and Prunum shell beads, and stone and coal beads from Webb and Moore excavations at Indian Knoll (15OH2) are discussed in this paper as the author seeks to determine how beads were deployed to convey social information during the Archaic period. After wrestling with the count of beads (ca. 27,337) and the number of burials (ca. 260) with beads, the types of beads are tallied and measurements given based on the author’s examination of beads. The presence and distribution of beads in the shell-bearing stratum and the hardpan, and their distribution among women, men, and subadults, are explored. The beads appear to have been assembled rather than manufactured as sets. An argument is made that shell beads were used at Indian Knoll as regalia for members of and victims of a hunt god/spirit cult. Leptoxis sashes are identified in 36 burials and discussed as regalia. Bead co-occurrence with atlatls, faunal species, and violent death is examined as part of the hypothesized cult rituals.
