PRIMERA CARACTERIZACIÓN ARQUEOMÉTICA DE LADRILLOS TARDORROMANOS DE LA CUENCA DEL RÍO DNIÉSTER Y COMPARACIÓN CON EL MATERIAL ALTOMEDIEVAL

The paper presents the results on archaeometric characterization of a test sample of building materials from the settlements of the Late Roman period Komariv and Buzovytsia-1 in the middle course of the Dniester river. The parameters of raw material and technology of bricks from the two sites are compared and the first reconstruction of features of operational chains are offered. Also, the first comparison of the Late Roman period materials with same-function artifacts of the Middle Ages (Old Rus’ Culture) has been made. The development of petrographic and geochemical classification of archaeological building ceramics from the sites of the Central and South-West Ukraine was started.El artículo presenta los resultados de la caracterización arqueométrica de una muestra preliminar de materiales de construcción de los asentamientos de la época romana de Komariv y Buzovytsia-1 en el curso medio del río Dniéster. Se comparan los parámetros de la materia prima y la tecnología del zócalo de los dos sitios y se ofrece la primera reconstrucción de las características de las cadenas operativas. También se ha realizado la primera comparación de los materiales del periodo romano tardío con los artefactos de la misma función de la Edad Media (la antigua cultura de la Rus). Se inició el desarrollo de la clasificación petrográfica y geoquímica de la cerámica de construcción arqueológica de los monumentos del centro y suroeste de Ucrania

Shifts in the Genetic Landscape of the Western Eurasian Steppe Associated with the Beginning and End of the Scythian Dominance

The Early Iron Age nomadic Scythians have been described as a confederation of tribes of different origins, based on ancient DNA evidence [1-3]. It is still unclear how much of the Scythian dominance in the Eurasian Steppe was due to movements of people and how much reflected cultural diffusion and elite dominance. We present new whole-genome sequences of 31 ancient Western and Eastern Steppe individuals, including Scythians as well as samples pre- and postdating them, allowing us to set the Scythians in a temporal context (in the Western, i.e., Ponto-Caspian Steppe). We detect an increase of eastern (Altaian) affinity along with a decrease in eastern hunter-gatherer (EHG) ancestry in the Early Iron Age Ponto-Caspian gene pool at the start of the Scythian dominance. On the other hand, samples of the Chernyakhiv culture postdating the Scythians in Ukraine have a significantly higher proportion of Near Eastern ancestry than other samples of this study. Our results agree with the Gothic source of the Chernyakhiv culture and support the hypothesis that the Scythian dominance did involve a demic component.status: publishe
