Palynological and Archaeological Evidence for Ritual Use of Wine in the Kura-Araxes Period at Aradetis Orgora (Georgia, Caucasus)

Pollen and non-pollen palynomorphs found in two zoomorphic Kura-Araxes vessels (ca. 3000 BCE) from Aradetis Orgora suggest they were utilized for the ritual consumption of wine and likely represent the beginning of the enduring tradition of animal-shaped wine-drinking containers in Georgia. This hypothesis is supported by archaeological and geoarchaeological data: the vessels resemble later wine-containing vessels from Georgia and elsewhere and were found in a building whose context is suggestive of a small shrine. Their palynological spectra match those of present-day wine and wine containers of other periods. One of the vessels was intact, with only a small access hole, that hindered the contamination of its contents; consequently, its palynological spectrum can be utilized as a standard for determining the presence of wine in other archaeological vessels. The analysis of pollen and non-pollen palynomorphs from different contexts at the Aradetis Orgora settlement and from its cemetery (Doghlauri) yielded other significant results regarding the practice of viticulture and the cultural relevance of wine during the Kura-Araxes period

Archaeological Investigations at Chobareti in southern Georgia, the Caucasus

International audienceOnce a restricted military zone, the Akhaltsikhe-Aspindza region within the Samtskhe-Javakheti province of Georgia is now the focus of archaeological investigations. This paper brings together the main data from three years of fieldwork at the ancient site of Chobareti, situated at 1610 metres above sea level, which has so far revealed a Kura-Araxes settlement and burials, and a late Antique/Medieval stronghold

Archaeobotanical and isotopic evidence of Early Bronze Age farming activities and diet in the mountainous environment of the South Caucasus: A pilot study of Chobareti site (Samtskhe-Javakheti region)

Recent excavation at the site of Chobareti (1615 m a.s.l., South Caucasus Mountains) reveals an important Kura-Araxes settlement and eleven burials so far, for which a first multi-proxies approach was conducted to understand both exploitation of plants and human dietary practices in this mountainous area. Thanks to the excavation of several pits, in 2011, a well-reasoned sampling for archaeobotanical analysis, including phytoliths, pollen and non-pollen palynomorphs, charcoal, seeds and other plant macroremains was undertaken. In parallel, human, animal bones and wheat seeds were recovered in order to perform stable isotope analysis (δ13C, δ15N). Results show the strong presence of cereals (especially naked wheat, as a hexaploid form, and emmer), highlighting the role played by cereal growing in the Kura-Araxes farming activities. Plant macroremains, but also phytoliths recovered in pits, reflect processing activities on the site. While animal dung seems to have been used to enhance cereal yields, different herding practices can be suggested by δ15N values. Whereas δ13C values and archaeobotanical data agree for a consumption of C3 plants, with no significant input in wheat for both animals and humans, a homogeneous mixed diet, with a great contribution of animal protein source (meat, secondary products) has been observed

New pollen evidence from Nariani (Georgia) for delayed postglacial forest expansion in the South Caucasus

International audienceThe nature and timing of environmental changes throughout the last glacial-interglacial transition in the South Caucasus, and more widely in eastern Europe, are still not fully understood. According to certain pollen records, forest expansion occurred in many areas several millennia after what is considered worldwide as the onset of the Holocene. The current problem we face is that the time lag in forest expansion varies from one sequence to another, sometimes with no delay at all. Moreover, the potential forcing/controlling factors behind this complex pattern, contrary to the almost synchronous global Holocene warming, are still a matter for debate. Accordingly, we revisit the issue of forest expansion through vegetation history obtained in the South Caucasus using a new pollen record, retrieved from the Nariani paleolake (South Georgia). These data attest to a steppic phase, initially dominated by Amaranthaceae-Chenopodiaceae (12,700–10,500 cal yr BP), then by Poaceae (10,500–9000 cal yr BP), culminating with a more forested phase (9000–5000 calyrBP). Although some palaeoclimatic regional reconstructions show a wet early Holocene, we interpret the delay in forest expansion recorded in Nariani (2500 years) as the result of reduced spring precipitation, which would have limited forest development at that time
