Phytolith evidence for the pastoral origins of multi-cropping in Mesopotamia (ancient Iraq)

Multi-cropping was vital for provisioning large population centers across ancient Eurasia. In Southwest Asia, multi-cropping, in which grain, fodder, or forage could be reliably cultivated during dry summer months, only became possible with the translocation of summer grains, like millet, from Africa and East Asia. Despite some textual sources suggesting millet cultivation as early as the third millennium BCE, the absence of robust archaeobotanical evidence for millet in semi-arid Mesopotamia (ancient Iraq) has led most archaeologists to conclude that millet was only grown in the region after the mid-first millennium BCE introduction of massive, state-sponsored irrigation systems. Here, we present the earliest micro-botanical evidence of the summer grain broomcorn millet (Panicum miliaceum) in Mesopotamia, identified using phytoliths in dung-rich sediments from Khani Masi, a mid-second millennium BCE site located in northern Iraq. Taphonomic factors associated with the region’s agro-pastoral systems have likely made millet challenging to recognize using conventional macrobotanical analyses, and millet may therefore have been more widespread and cultivated much earlier in Mesopotamia than is currently recognized. The evidence for pastoral-related multi-cropping in Bronze Age Mesopotamia provides an antecedent to first millennium BCE agricultural intensification and ties Mesopotamia into our rapidly evolving understanding of early Eurasian food globalization.

Ways of Being: Hittite Empire and Its Borderlands in Late Bronze Age Anatolia and Northern Syria

In this paper, I take identity as a characteristic of empire in its periphery, denoting the totality of: 1) the imperial strategies an empire pursues in different regions, 2) the index of empire in each region, and 3) local responses to imperialism. My case study is the Hittite Empire, which dominated parts of what is now modern Turkey and northern Syria between the seventeenth and twelfth centuries BCE, and its borderlands. To investigate the identities of the Hittite imperial system, I explore the totality of the second millennium BCE in two regions. First, I explore imperial dynamics and responses in the Ilgın Plain in inner southwestern Turkey through a study of the material collected by the Yalburt Yaylası Archaeological Landscape Research Project since 2010. Second, I explore the identity of the Hittite Empire in the city of Emar in northern Syria by a thorough study of the textual and archaeological material unearthed by the Emar Expedition. In both cases, I argue that the manifestations of the Hittite Empire were mainly conditioned by the pre-Hittite trajectories of these regions. The strategies that the administration chose to use in different borderlands sought to identify what was important locally, with the Hittite Empire integrating itself into networks that were already established as manifestations of power, instead of replacing them with new ones.

Integrating Satellite, UAV, and Ground-Based Remote Sensing in Archaeology: An Exploration of Pre-Modern Land Use in Northeastern Iraq

Satellite remote sensing is well demonstrated to be a powerful tool for investigating ancient land use in Southwest Asia. However, few regional studies have systematically integrated satellite-based observations with more intensive remote sensing technologies, such as drone-deployed multispectral sensors and ground-based geophysics, to explore off-site areas. Here, we integrate remote sensing data from a variety of sources and scales including historic aerial photographs, modern satellite imagery, drone-deployed sensors, and ground-based geophysics to explore pre-modern land use along the Upper Diyala/Sirwan River in the Kurdistan Region of Iraq. Our analysis reveals an incredible diversity of land use features, including canals, qanats, trackways, and field systems, most of which likely date to the first millennium CE, and demonstrate the potential of more intensive remote sensing methods to resolve land use features. Our results align with broader trends across ancient Southwest Asia that document the most intensive land use in the first millennium BCE through the first millennium CE. Land use features dating to the earlier Bronze Age (fourth through second millennium BCE) remain elusive and will likely require other investigative approaches.

Potters in Transition

For many years, the Late Bronze/Iron Age transition in the southern Levant has been the subject of intense debates concerning chronological matters and cultural developments. Ceramic studies were often the focal point of the discussion, but they usually concentrated on the appearance of Aegean-style pottery in the southern Coastal Plain and the nearby Shephelah, while largely disregarding the indigenous pottery tradition. In this paper, I study the processes of continuity and change in ceramic shape morphology and decoration techniques of three important tell-sites in the Shephelah: Lachish, ʿAzẹqȧ (Tel Azekah) and Ekron. It will be shown that marked innovations took place during the transition to the Iron I. These were most likely triggered by the appearance of foreign potters who produced local Aegean-style wares and seem to have influenced the traditions of the indigenous ceramic workshops. Such insights not only allow a fine-tuning of the relative chronology of the region at the end of the second millennium BCE, but also illuminate the transmission of professional knowledge and cultural traits through the ages.

Mining under the early metal in the context of Kartamysh ore occurrence of Ukrainian Donbas

Purpose is to identify process engineering of mining under the Late Bronze age (18th-13th centuries BCE) in the context of copper deposits in the Eastern Ukraine. Among other things, it concerns analysis of manufacturing artifacts (i.e. ore production and preparation) in Kartamysh archeological area within the copper-ore territory of Bakhmut basin of Donbas. Methods. Following methods have been applied: a comparative historical method supported by typological archaeological approach; statistical procedures; engineering and geological methods to determine extraction volumes and evaluate copper ore extraction from the mines in Kartamysh archaeological area as well as structural and technologic analysis; functional and typological analysis; traceological analysis; experimental modelling; and carbon dating. Findings. Analysis of the specialized mining artifacts in Kartamysh archaeological area as well as mining artifacts within other copper-ore deposits in Bakhmut basin, extracted actively under the Late Bronze age, has made it possible to consider newly a number of important issues connected with process engineering of mining, specialization and labour division of ancient miners as well as evaluate significance of Donbas copper mines for the system of metal production development in the Eastern Europe of the second millennium BCE. Originality.Analysis of Kartamysh archaeological area, where the majority of business performance objects are connected with mining, has helped the authors consider specialization of the industrial systems (i.e. different-purpose mine workings, various mining tools, and areas to prepare ore) right from the viewpoint of the production method. Since similar situation is typical for other Donets complex artifacts, being involved in scientific terminology as the mining and smelting one, it would be more reasonable to represent it as Donets ore mining system owing to its specialization in the integrated copper ore extraction and preparation. Practical implications.The research results develop the history of mining science and engineering inclusive of ancient mining history in the Eastern Ukraine. They may be applied to train mining experts and in the process of creation of museum exhibitions (looking ahead, creation of Kartamysh skansen) while synthesizing technical and humanitarian aspects of engineering activities.

Long-term decrease in Asian monsoon rainfall and abrupt climate change events over the past 6,700 years

Asian summer monsoon (ASM) variability and its long-term ecological and societal impacts extending back to Neolithic times are poorly understood due to a lack of high-resolution climate proxy data. Here, we present a precisely dated and well-calibrated tree-ring stable isotope chronology from the Tibetan Plateau with 1- to 5-y resolution that reflects high- to low-frequency ASM variability from 4680 BCE to 2011 CE. Superimposed on a persistent drying trend since the mid-Holocene, a rapid decrease in moisture availability between ∼2000 and ∼1500 BCE caused a dry hydroclimatic regime from ∼1675 to ∼1185 BCE, with mean precipitation estimated at 42 ± 4% and 5 ± 2% lower than during the mid-Holocene and the instrumental period, respectively. This second-millennium–BCE megadrought marks the mid-to late Holocene transition, during which regional forests declined and enhanced aeolian activity affected northern Chinese ecosystems. We argue that this abrupt aridification starting ∼2000 BCE contributed to the shift of Neolithic cultures in northern China and likely triggered human migration and societal transformation.
