Natalia Shishlina Eurasian Steppe Bronze Age nomadism: main research achievements (A) Economy of Eurasian Steppe Bronze Age nomadism as a specific adaptive system. ●● We discuss the economy of the Caspian Steppes and environmental changes in the time interval of 4300 – 2000 BC. The results are based on the study of the soils buried under barrows, pollen and phytolith data. Six time intervals have been identified, including a period of the environmental disaster at 2400-2300 calBC. ●● A large number of samples from buried soils under barrows have been analyzed (pollen and phytolith analyses, flotation) but no domesticated cereals have been found. The economic model discussed was based only on animal husbandry (sheep, cattle and horse); collection of steppe plants and roots; fishing and hunting played a secondary role. The importance of horse has been identified. ●● The system of grassland seasonal use has been identified (based on complex analyses of animal and human teeth, pollen, egg-shells). Seasonal short and long distance movements have been identified for different cultures. Several models of seasonal cycles have been proposed. ●● A specific food acquisition system has been identified through: 1) pollen and phytolith analyses of the specific archaeological context, i.e. vessel residue, stomach area residue as well as human inter-dental space residue, 2) 13C and 15N measurements for human and animal collagen, 3) analyses of human bones (palaeo-pathology) The main results are the following: 1) all edible plants were wild, there is no evidence (at least, for the eastern part of the Eurasian Steppe) of domesticated cereal use in the diet in all cultures, including the Steppe Majkop population; 2) the use of drugs in the diet has been identified, such as Cannabis, Ephedra and Artemisia, 3) the stable isotope ratio of humans from different cultures shows that all individuals had a diet based largely on river and lake food (fish, water plants, molluscs). Production in steppe societies ●● 1) The textile industry of Eneolithic – Bronze Age cultures has been studied for many years. Weaving and plaiting were important crafts in everyday life of pastoralists. There are no data on wool fibres used by Yamnaya weavers. All wool and cotton cloth obtained from Majkop kurgans were imported from the Near East. Wild plants were used for making threads. Wool fibres did not appear in the Steppes until the Catacomb culture, i.e. after 2400 calBC. Primitive looms have been reconstructed; 2) A project devoted to the (Steppe and the North Caucasus) production of faience beads has been carried out. Local production of faience beads has been identified. Some beads were imported (from the South Caucasus, the Central Asia); 3) A bone tool industry has been reconstructed. Exchange systems ●● Multi-stage exchange transactions have been reconstructed, dictated by the need to obtain metal, metal tools and weapons as well as social position and status indicating objects, such as jewellery, between the Steppe and the Caucasus populations. In exchange for prestige goods and scarce materials, the steppe population could offer smoked and dry meat and fish, dairy products, home-made products, i.e. leather and textile items and bone jewellery. Hence, a complex model of the Eurasian pastoralist economy has been developed. (B) Excavation of Bronze Age – Early Iron Age sites ●● The site exploitation territory has been identified. ●● Environmental conditions of the site (through pollen and phytolith analyses of buried soil and soils taken from the inter-dental space of animals) have been identified. ●● Seasonality of pastoral camp-sites has been defined. (C )Chronology of Bronze Age Eurasian steppe cultures ●● 14C dating of different samples obtained from Eneolithic-Early Iron Age sites has been carried out. ●● The reservoir effect in the human bone collagen of all cultures discussed has been defined. ●● The reservoir effect correction for Bronze Age cultures of the Eurasian Steppes has been proposed.
