日本泉屋博古馆所见先秦私文书——商青铜私文书的兴起

日本泉屋博古馆收藏并展示的我国早年流散到海外的部分先秦青铜器,是中国先秦文化不可缺少的重要内容之一。商青铜私文书只是先秦私文书的一部分,并非是我国最早的私文书。“九五”期间国家重大科研课题“夏商周断代工程”的某些研究成果表明,商以前就已有文书记录产生,如再加以考古出土实物印证,夏就有可能是先秦私文书的起源时期,为此,笔者将商只作为中国青铜私文书的兴起阶段。     

Dietary Variability During Bronze Age in Central Italy: First Results

This research aims at delineating the dietary practices in Central Italy during the Bronze Age. The study of food choices is a mean for investigating palaeoenvironmental agricultural and economic activities and social relationships, which have been little explored until now in Italy from this specific perspective. Recent researches have showed that the Middle Bronze Age is a crucial period of dietary changes in Italy. Following these first observations, we studied three Bronze Age sites in Tuscany and Latium: Grotta dello Scoglietto, Grotta Misa and Felcetone. Analyses of stable carbon, nitrogen and sulphur isotopes on 38 human and 22 animal collagen samples were performed. The results show three different dietary patterns. Data from Grotta dello Scoglietto (Early Bronze Age) indicate a high‐protein intake, with a probable consumption of fish. Additionally, sulphur results let us infer the presence of some non‐local people. Individuals from Felcetone (Initial phase of the Middle Bronze Age) show a terrestrial diet dominated by plant proteins, which suggests a low δ¹⁵N food intake, namely legumes, as well as C₄ plant, such as millet. Finally, values from Grotta Misa (Middle Bronze Age) highlight a mixed terrestrial diet and the consumption of millet. Given the variety of the obtained results, we are able to conclude that the transition from the Early to the Middle Bronze Age represents a moment of change, which is reflected by the presence of different dietary patterns.

European Pond Turtles from Obříství (Bohemia,Czech Republic)

The paper describes and analyses recent finds of the European pond turtle (Emys orbicularis) from the archaeological sites at Obříství (Mělník District, at the confluence of the Elbe and Moldau rivers in the Bohemian Basin, Czech Republic). Turtle remains were found in three sunken features dated to the Late Bronze Age or to the Hallstatt period, and in one feature dated to the Neolithic. The high number of osteological finds, particularly the number of individuals found in one place, is unique within Bohemia and very rare for the Bronze Age to Iron Age in Europe. A large number of shell remains were identified, from at least 12 individuals in feature 1480, and from at least 5 individuals in feature 1483. The high numbers support the hypothesis that the European pond turtle was once a regular feature of the local fauna, even though the Bohemian basin is surrounded by mountains, which will have presented difficulties for the process of postglacial recolonization by semiaquatic thermophilous reptiles. The findings from Obříství show evidence of the exploitation of turtles for food. Signs of culinary procedures and the human consumption of turtles include anthropogenic chop marks, signs of burning and the apparently intentional segmentation of the turtle bodies. The quantity of turtle bones is still negligible, however, compared with those of mammals. Copyright © 2015 John Wiley & Sons, Ltd.     

Human Response to Climate Change during the Umm an‐Nar/Wadi Suq Transition in the United Arab Emirates

Stable oxygen isotope ratios in archaeological human dental enamel represent an under‐utilised tool in the examination of changing climatic patterns in the ancient world. In the Oman Peninsula at the end of the third millennium bc , rapid aridification was accompanied by a breakdown in interregional trade relations; however, the human response to these changes is poorly understood. At the Bronze Age necropolis at Shimal in the United Arab Emirates, dental enamel from individuals interred in both Umm an‐Nar (ca 2700–2000 bc ) and Wadi Suq (ca 2000–1300 bc ) tombs underwent oxygen, strontium and carbon isotope analyses to examine how local inhabitants of southeastern Arabia responded to both environmental and socioeconomic change. While individuals from Shimal exhibit a clear shift in mean δ¹⁸O_c(VPDB) values from the Umm an‐Nar (−3.5 ± 0.6‰, 1σ) to the Wadi Suq (−2.4 ± 0.9‰, 1σ), corresponding ⁸⁷Sr/⁸⁶Sr and δ¹³C_ap signatures display homogeneity indicative of continuity in Bronze Age lifeways. Together, these data highlight the ability of local communities to successfully adapt to their changing environs (in lieu of societal collapse or a shift to a more mobile lifestyle) in an effort to maintain their way of life.

The provenance and distribution of Early Bronze ceramics in the Kolyaei Plain,central Zagros,Iran

Within Iran, there is little archaeological evidence for relationships between newly arrived Early Trans-Caucasian (ETC) or Kura-Araxes settlers and earlier inhabitants and contact with neighbouring cultures, or for their apparently abrupt end. Based on the evidence, the Iranian Kura-Araxes was not a simple ‘copy' of the Caucasian Kura-Araxes package. Ceramic traditions show local peculiarities, and all are elements suggesting that the Kura-Araxes traditions went through processes of adaptation, change and re-elaboration according to local tastes and technologies. In this study, an archaeometric approach to ceramics in the Kolyaei Plain of central Zagros contributes to the discussion of contact and exchange between indigenous communities and several cultural spheres of influence on the Early Bronze Age (beginning in the fourth millennium bce ). Morphological data, as well as the mineralogical and chemical composition of ceramics, were applied to determine the major and trace elements of the pottery shards. Based on the trace element profiles, it can be suggested that all the pottery shards are in the same group and they strongly are local products. The ceramic provenance indicates the same patterns of material interactions during the ETC or Kura-Araxes in all the sites within the Kolyaei Plain.     

Dating and provenance of glass artefacts excavated from the ancient city of Tall Zirā‛a,Jordan

Fourteen glass objects recovered from excavations at the ancient city of Tall Zirā‛a, Jordan, were analysed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to determine the period and origin of manufacture. The composition of glasses manufactured in the Late Bronze Age (LBA) and Iron Age are distinctly different, therefore major element analysis can be used to distinguish between the groups relatively easily. The LA-ICP-MS analysis provided quantitative trace element data which were used to determine the provenance of those glasses identified as LBA. This research discusses the implications of the presence of both Egyptian and Mesopotamian LBA glasses and examines the varying compositions and colour strategies employed in both the LBA and Iron Age objects. Specifically, glass in the LBA was considered to be one of the highest status items attainable, playing an instrumental role in diplomatic gift-giving. When considered with the archaeological information, the significance of these finds at Tall Zirā‛a indicates that this city was a settlement of high status, not primarily a convenient trading stop on the Transjordan route.
