Contexts for Conflict: Conceptual Tools for Interpreting Archaeological Reflections of Warfare

Abstract

There has been a long history of interest in the material remains of conflict, but in the last two and a half decades archaeologists have made strides in the study of war and warfare. Techniques have been developed, refined, and borrowed to expose the material record of combat. Sites associated with other military undertakings have been discovered and the material culture of conflict has been documented. This growth has expanded an understanding of past conflicts and challenged previously held ideas about warfare. Although archaeologists do not currently have interpretive frameworks to link the diverse sites and objects that form the archaeological record of war, modern military planners have developed such models. This paper uses sites from the North American Great Plains to suggest that military models of conflict analysis can contribute to a synthetic archaeological interpretation of conflict.     

EVALUATION OF THE APPLICABILITY OF CONVENTIONAL METHODS FOR THE CHEMICAL CHARACTERIZATION OF WATERLOGGED ARCHAEOLOGICAL WOOD

A series of 112 waterlogged archaeological wood samples of different provenances, wood species, burial times and states of preservation were analysed with the aim of assessing the validity (in terms of limits and reliability) of procedures conventionally used in the pulp and paper industry, to evaluate the state of preservation of decayed wood. In particular, the extent of any damage wrought on decayed wood tissue by the repetitive cycles that characterize these procedures was evaluated as a function of the degradation of the samples. The results indicated that standard methodologies give reliable measurements regardless of the extent of wood decay. However, it is essential to compare these data with those of non‐decayed wood that has been measured using the same procedures to take account of the errors that are inherent in these methodologies and that affect measurements.     

Crema Ware and Elite Power at Monte Albán: Ceramic Production and Iconography in the Oaxaca Valley,Mexico

Abstract

During the Terminal Formative, or Monte Albán II period (ca. 100 B.C.-A.D. 200), the Zapotec state was centered in the Oaxaca Valley, Mexico. Reassessment of ceramic data from excavations at the Zapotec capital of Monte Albán, in conjunction with data acquired from recent investigations at a secondary center (Cerro Tilcajete) and a tertiary center (Yaasuchi) in the Oaxaca Valley, sheds light on the production and distribution of elaborately decorated crema- (cream-) paste ceramics. This analysis suggests that such ceramics were produced at Monte Albán as prestige goods and distributed to local elites residing at administrative sites throughout the valley. The distribution of decorated crema vessels—and in particular, bowls bearing incised lightning motifs associated with the preeminent Zapotec deity, Cociyo—via gift-giving networks represented an attempt by elites at the capital to control local elites and integrate them into the regional sociopolitical hierarchy. Data from Cerro Tilcajete and Yaasuchi indicate that local elites at these centers acquired and used some crema vessels. These vessels were fewer in number and less varied than the cremas enjoyed by elites at the capital. Elites at Cerro Tilcajete and Yaasuchi apparently sponsored the local production of ceramics intended to imitate crema vessels. By supplementing the flow of true crema ceramics from Monte Albán, the production of local imitations would have subverted attempts by elites at the capital to control both the distribution of prestigious ceramics and the subordinate elites who desired them. This regional study of ceramics in the Oaxaca Valley illustrates the intersection of economy and ideology in state society, as well as the role that prestige goods can play in the creation and legitimization of—as well as resistance to—institutionalized sociopolitical difftrences.     

STAINING OF ARCHAEOLOGICAL GLASS FROM MANGANESE‐RICH ENVIRONMENTS*

It has been suggested that both internal and external sources of manganese may produce the black or brown staining that often occurs in buried archaeological glass. Modern potash glass of a manganese‐free medieval composition was scratched, etched and immersed in an aqueous solution containing dissolved manganese. After several weeks, immersion samples were sectioned and examined by SEM–EDX. Manganese was shown to be present in fissures and cracks within in the glass, where alkali had been depleted. Manganese from an external source is capable of blackening buried medieval potash glass.     

NEW EVIDENCE FOR EARLY SILK IN THE INDUS CIVILIZATION*

Silk is an important economic fibre, and is generally considered to have been the exclusive cultural heritage of China. Silk weaving is evident from the Shang period c. 1600–1045 bc , though the earliest evidence for silk textiles in ancient China may date to as much as a millennium earlier. Recent microscopic analysis of archaeological thread fragments found inside copper‐alloy ornaments from Harappa and steatite beads from Chanhu‐daro, two important Indus sites, have yielded silk fibres, dating to c. 2450–2000 bc . This study offers the earliest evidence in the world for any silk outside China, and is roughly contemporaneous with the earliest Chinese evidence for silk. This important new finding brings into question the traditional historical notion of sericulture as being an exclusively Chinese invention.     

NON‐DESTRUCTIVE ANALYTIC METHOD USING XRF FOR DETERMINATION OF PROVENANCE OF ARCHAEOLOGICAL OBSIDIANS FROM THE MEDITERRANEAN AREA: A COMPARISON WITH TRADITIONAL XRF METHODS*

A non‐destructive analytical method using wavelength‐dispersive X‐ray fluorescence (WDXRF) that allows the establishment of the provenance of archaeological obsidians was developed and a comparison with the classical XRF method on powders is discussed. Representative obsidian samples of all the geological outcrops of archaeological interest of the Mediterranean area (Lipari, Pantelleria, Sardinia, Palmarola and the Greek islands of Melos and Gyali), were analysed with the normal procedures used in rock analysis by XRF (crushing, powdering and pelletizing). The non‐destructive XRF analysis was instead conducted on splinters taken from the original geological pieces, with the shape deliberately worked to be similar to the refuse usually found at archaeological sites. Since the analysis was conducted on the raw geological fragment, intensity ratios of the suitably selected chemical elements were used, instead of their absolute concentrations, to avoid surface effects due to the irregular shape. The comparison between concentration ratios (obtained by traditional XRF methods) and the intensity ratios of the selected trace elements (obtained from the non‐destructive methodology) show that the different domains of the chemical composition, corresponding to the geological obsidians of the source areas, are perfectly equivalent. In the same way, together with the geological splinters, complete archaeological obsidians, from Neolithic sites, may be analysed and their provenance may be determined. The proposed non‐destructive method uses the XRF method. Due to its sensitivity, low cost and high speed, it is surely an extremely valid instrument for the attribution of the provenance of the archaeological obsidian from Neolithic sites.     

NEUTRON ACTIVATION ANALYSIS OF ARCHAEOLOGICAL MATERIALS: AN OVERVIEW OF THE ITN NAA LABORATORY,PORTUGAL

Instrumental neutron activation analysis (INAA) has been applied to archaeological samples at the Portuguese Research Reactor (RPI) since 1973, and the number of samples analysed has increased steadily since the mid‐1990s. Archaeometric applications of INAA at RPI include the analysis of archaeological ceramics and the stones used in monumental architecture (menhirs) and other historical monuments. A programme of analysis also exists for measuring the precision of and contributing to the certified values of geochemical reference samples. In addition, the study of interference factors is performed to obtain better accuracy in the determination of concentrations of some elements (e.g., corrections for spectral interferences from uranium fission products in the determination of barium, rare earth elements and zirconium).     

Traces of Fatty Acids from a Byzantine Sounding Lead Recovered off the Israeli Coast

Fatty acids, typical to large herbivores, were isolated from a 7th century Byzantine sounding lead recovered from a shipwreck off Dor, an ancient anchorage in Northern Israel. The fatty acids survived by being sheltered in an anaerobic environment provided through a site formation process induced by the disintegrating wreck. Previously established identification criteria for fatty acids, absorbed in ceramics, were used to show that tallow was used in this navigational instrument in the Eastern Mediterranean during late antiquity.     

MANGANESE STAINING OF ARCHAEOLOGICAL GLASS: THE CHARACTERIZATION OF Mn‐RICH INCLUSIONS IN LEACHED LAYERS AND A HYPOTHESIS OF ITS FORMATION

During the study of a large number of archaeological glass fragments, manganese‐rich inclusions in leached layers were observed in a limited number of cases. This phenomenon occurs only in black‐coloured leached layers. Since the formation mechanism of such manganese‐rich inclusions is still unclear, a combination of several analytical techniques was used in order to investigate this phenomenon and, more specifically, to obtain more information on (a) the composition and morphology of the inclusions, (b) the chemical state of Mn and (c) the 3D morphology of the inclusions. A mechanism that might explain the formation of these inclusions is proposed.
