ABSTRACT Large-scale Lidar surveys have revitalized interest in regional settlement studies in the Maya Lowlands. Remotely identified features in Lidar imagery must be verified on the ground, with results of ground-truthing studies forming the basis of reliable, comparative databases for understanding ancient Maya land use and modification. The El Pilar Project integrates data generated by established survey methods with Lidar imagery to construct more complete pictures of settlement distribution, landscape modification, and human-environment interactions. This paper describes the results of Lidar-guided survey at El Pilar along with the protocol our project developed to systematize data collection and increase the efficiency of survey. The methods we describe have proven effective for investigating Maya settlement patterns at the site scale and locating features difficult to discern in Lidar imagery.

ABSTRACT Sb was frequently used as a raw material, both in ancient glass-making (as an opacifier and decolouriser) and metallurgy (either as an alloying element or as a pure metal). Despite this ubiquity, antimony production has only occasionally been studied and questions concerning its provenance are still not satisfactorily answered. This study evaluates the suitability of Sb isotope analysis for provenance determination purposes, as experiments under lab conditions have revealed fractionation occurring during redox processes in oxidising stibnites and in making opacified glasses. The results of this paper help to evaluate the possible influence of the pyrotechnological processes on the antimony isotope composition of glass artefacts. This paper focuses on the Caucasus as case study by applying mineralogical, geochemical and isotopic analysis to Georgian ores (mainly from the Racha-Lechkumi district) and Late Bronze Age (LBA; 15th–10th century BCE) metallic Sb objects found at the sites of Brili and Chalpiragorebi.

ABSTRACT The amount of prehistoric metal items discovered in the Maltese archipelago during the BronzeAge very limited in number. The majority of the artifacts are traditionally considered Aegean imports from nearby Sicily. Nineteen objects, currently on display in the National Archaeological Museum of Valletta, and dated between the 17th and 12th century BCE, represent the main evidence of metalwork in Malta during the Bronze Age. Daggers, axes, vessels, rings, pins and an ingot were found in Early and Middle/Late Bronze Age sites and were traditionally interpreted as made from bronze solely on the account of a direct visual exam. The aim of this contribution is to present the results of research carried out on those artifacts applying non-destructive portable X-ray fluorescence spectrometry (pXRF) in order to ascertain their chemical composition, to compare the data with those available for Sicily and the Aegean and discuss the archaeological implications of such outcomes.

ABSTRACT The collection Manuscripta Americana in Berlin consists of fragmented codices acquired by Alexander von Humboldt in Mexico. Some of these Humboldt Codices are published as hieroglyphic writings of the Aztecs in “Vues des Cordilleres et Monuments des Peuples indigènes de l’Amerique”. Starting from a special compilation of seven fragments on plate 36 in the “Atlas”, we investigated the corresponding original fragments using material analysis in order to clarify their historical relations. The analyses were carried out with X-ray fluorescence analysis, VIS spectroscopy, and infrared spectroscopy in diffuse reflection and revealed typical indigenous colors like cochineal, indigo, and organic yellows (e.g. mangrove and zacatlaxcalli). Four fragments under investigation show exactly the same material and thus must once have belonged together in one compendium. An additional manuscript from Mizquiahuala also shown on plate 36 can be matched to another one that is not published in the “Atlas”.
柏林收藏的美国手稿由亚历山大·冯·洪堡在墨西哥获得的碎片抄本组成。这些洪堡抄本中的一些被作为阿兹特克人的象形文字出版在“Vues des Cordilleres et Monuments des peoples indigires de l ' america”。我们从《地图集》第36版七段碎片的特辑开始，用材料分析的方法考察了相应的原始碎片，以厘清它们之间的历史关系。通过x射线荧光分析、可见光谱和漫反射红外光谱进行分析，发现了典型的土着颜色，如胭脂虫红、靛蓝和有机黄(如红树林和zacatlaxcalli)。正在调查的四个碎片显示出完全相同的材料，因此一定曾经属于一个纲要。第36版上还显示了另一份来自米兹奎瓦拉的手稿，可以与《地图集》中未发表的另一份手稿相匹配。

ABSTRACT In archaeological research about feeding modes of past societies, different interests and methodologies have been developed. In their search for knowledge about Mayan foods and cooking methods, scholars such as Herrera Flores and Götz [2014. “La alimentación de los antiguos mayas de la Península de Yucatán: Consideraciones sobre la identidad y la cuisine en la época prehispánica.” Estudios de Cultura Maya 43 (43): 69–98. doi:10.1016/S0185-2574(14)70325-9] have paid attention to available resources, diet, and cuisine. Food is more than food intake, as it also relates to other aspects like health, identity, gender roles, worldview, memory, and emotions. For the Classic Maya site of Sihó, Yucatan, our case study, the research is oriented towards the gastronomy of the elites. Through the study of chemical residues and identification of starch granules in ceramic fragments of five types of containers namely dishes, bowls, jars, vases, and basins. This study aimed at identifying related ingredients, preparation processes and service practices, suggesting particular ways of cooking and consumption patterns. The test results were compared and supplemented with zooarchaeological evidence, iconography, historical and ethnographic records.

ABSTRACT An analytical study is presented, aimed to determine the elemental composition of copper-based artefacts dated back from Copper Age to Early Iron Age (mid-fourth millennium to the VIIIth century B.C.), found on the Tyrrhenian side of the peninsula, corresponding to the Lazio region. The objects belong to different archaeological contexts and had various functions. They were analysed by the X-ray fluorescence technique. The results highlight the experimental character of Copper Age metallurgy, which will later evolve in the established use of copper-tin alloys. Regarding the Bronze Age, despite the typological and functional heterogeneity of the artefacts and the wide chronological range, the alloys are relatively homogeneous in composition, with regular changes that appear related to chronology, according to what is already known for the Italian peninsula. Such changes are supposedly due to variations in the availability of tin, which was not locally mined. Early Iron Age metallurgy is represented by the Selvicciola Hoard solely, which restricts the possibility of generalizing the conclusions. A striking feature of the alloys is the great compositional difference between the complete and the fragmented artefacts. The formers are made of tin bronze, whereas in the latter tin is replaced by antimony and/or lead. The use of such unusual alloys is unlikely due to lack of metallurgical knowledge. Considering the urbanized communities that arose in the Middle-Tyrrhenian area during the Early Iron Age, we suppose that such variability in a single context might be related to a production system capable of using alloys of different quality and value to satisfy a diversified demand.

ABSTRACT Excavated glass artifacts are usually environmentally impacted, causing spatial inhomogeneity which poses great challenges for accurate and non-destructive chemical characterization. Here, we present our study on accurate characterization of archaeological glass with Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS), a high-precision and minimally destructive analytic method. Using three corroded glass beads excavated from Guangnan, Yunnan, Southern China as examples, we discuss the issues that may be involved when observing signal curves of highly inhomogeneous archaeological glass, as well as provide chemical characterization for the intact pristine body. Results indicate that these Indo-Pacific monochrome beads are of the potassium silicate glass type and used mineral potash source, and that they contain copper as the colorant. By discussing the breadth and depth types of inhomogeneity and focusing on perturbation endured by major elements, we identify the extent of environmental alteration and describe how different elements and matrices can respond differently to the archaeological environment, leading to various corrosion behaviors. For such samples LA-ICP-MS is shown to be an advantageous tool to provide archaeologically relevant information, or to probe artifact conditions for conservation purposes. A good understanding of sample conditions, and close attention to the experimental and calibration process are required to overcome inhomogeneity when tackling archaeological glass.

ABSTRACT Cobalt was commonly used as a colourant in the Egyptian glass industries of the 18th dynasty, dark blue glass being a regular find at palatial and settlement sites, including Amarna and Malqata. The main source of cobalt ore used during this period has been identified in the Egyptian western desert, around the oases of Kharga and Dakhla. In order to better understand the chaîne opératoire of Late Bronze Age glass production and -working, in particular with regard to cobalt ore, at Amarna, chemical analysis by portable X-Ray fluorescence was carried out in the field. This was done on contextualised archaeological material excavated at the site of Amarna, which cannot be exported from Egypt for analysis. The results of this study demonstrate how cobalt ore was used in the various known workshop sites at Amarna, resulting in a deeper understanding of raw materials use and exchange across this settlement.

ABSTRACT The composition of lead inclusions in modern and ancient leaded tin bronzes was studied by X-Ray Diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) in Scanning Electron Microscope (SEM). Lattice parameter of lead inclusions in all bronzes was smaller than the lattice parameter of pure lead. This determination indicates that lead inclusions in bronzes are nothing else but Pb–Sn solid solutions. Tin concentration in lead inclusions in modern bronzes was not less than 3 at% in accordance with the Pb–Sn phase diagram, tin concentration in lead inclusions of ancient bronzes was as low as 1 at%. This difference enables a distinction between ancient bronze artefacts and modern products including the most sophisticated fakes. On the other hand, our work demonstrates that the generally accepted Pb–Sn phase diagram corresponds to an incomplete equilibrium state and only after centuries-long aging at ambient temperatures does the Pb–Sn solid solution reach real equilibrium.

On the other hand, our work demonstrates that the generally accepted Pb–Sn phase diagram corresponds to an incomplete equilibrium state and only after centuries-long aging at ambient temperatures does the Pb–Sn solid solution reach real equilibrium.","PeriodicalId":21858,"journal":{"name":"STAR: Science & Technology of Archaeological Research","volume":"19 1","pages":"29 - 35"},"PeriodicalIF":0.0,"publicationDate":"2019-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77957085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Ancient monuments are puzzling from an evolutionary perspective. It is obvious that their construction would have been costly in terms of energy, but it is not clear how they would have enhanced reproductive success. In the late 1980s, Robert Dunnell proposed a solution to this conundrum. He argued that wasting energy on monuments and other forms of what he called “cultural elaboration” was adaptive in highly variable environments. Here, we report a study in which we used an agent-based model to test Dunnell’s hypothesis. We found that the propensity to waste was subject to strong negative selection regardless of the level of environmental variability. At the start of the simulation runs, agents wasted ca. 50% of the time but selection rapidly drove that rate down, ultimately settling at ca. 5–7%. This casts doubt on the ability of Dunnell’s hypothesis to explain instances of cultural elaboration in the archaeological record.
