Технологические и культурные традиции гончарства в среднем неолите Байкало-­Енисейской Сибири

Abstract

Introduction. The lack of known Middle Neolithic burial complexes in Baikal-Yenisei Siberia makes pottery finds from archaeological sites a key source to explore the cultural and historical situation in the region. According to AMS 14C-dates in the range of ~6,8–6,3 ka cal BP in the territory of Baikal-Yenisei Siberia, two types of ceramics are widespread — Posolsk and Ust-Belaya types. Goals. The study seeks to identify technological and cultural traditions of Middle Neolithic pottery. Materials and methods. The work examines Ust-Belaya and Posolsk type pottery samples from fifteen excavated sites of Baikal-Yenisei Siberia. The paper describes morphological and decorative patterns inherent thereto, provides technical and technological analyses following the methodology of A. Bobrinsky. The molding masses of eighteen Ust-Belaya type vessels and sixteen Posolsk type vessels have been studied with the aid of a binocular microscope. Results. In all cases, ferruginous sandy clay containing quartz sand had served as initial plastic raw material. Molding masses are characterized mainly by an unmixed one-component composition without artificial additives. In two cases, quartz grus has been identified, in another there are traces of organic matter (possibly added intentionally). Vessels of the Posolsk type have closed paraboloid forms with a weak profiling of the upper part and a sharpened bottom. The ornament is localized in the upper part of the vessel and is represented by horizontal ‘receding stick’ rows or drawn lines. The composition below ends with separate shapes, such as triangles or short vertical lines. The rim is decorated with prints of a comb stamp and has a line of round holes which is located over the line made by stick through drawing or receding techniques. The study of molding masses of sixteen Posolsk vessels demonstrates an unmixed one-component composition. In all cases, ferruginous sandy clay had been used as initial plastic raw material. The analysis of the modeling features of Middle Neolithic ceramics makes it possible to formulate hypothetical production programs of theirs. To check the latter, experiments were carried out to model the Ust-Belaya and Posolsk types of vessels. Technical and technological analyses, experiments conducted, and comparisons of models with archaeological vessels reveal technological traditions generally characteristic of Middle Neolithic pottery, such as the method of zonal patchwork modeling in combination with walls knocking out techniques, as well as the use of other vessels as base forms. So, Ust-Belaya vessels could have been completely made on such base forms, while upper parts of Posolsk vessels were profiled after removal from such forms. Knocking out tools for Posolsk ceramics included cord and carved shovels, and for Ust-Belaya type — smooth shovels sometimes wrapped with a woven net. Design patterns of the rim are also different. Conclusions. For the preparatory stage of Middle Neolithic ceramics production, there was a stable tradition of using local sandy clays without additives. The modeling principles common for the two types, along with the absence of flat-bottomed forms, reflect the same level of technological development and similar ideas about the making and functions of vessels, which does not necessarily indicate any ethnocultural closeness of culture bearers. Different traditions of morphology, techniques and decoration indicate that the pottery types belong to different populations. In Posolsk ceramics, there are autochthonous features bringing it closer to the Early Neolithic Khaita pottery. Ceramics of the Ust-Belaya type has no visible origins in the Early Neolithic of the region, which indicates its non-local origin. In addition, the materials of the campsites indicate that the bearers of these traditions had tended to choose different habitats.
