 Thank you. I guess it's obvious that the Roundbarrel Mound or Barrel Hüggigrat or Mojilla or Tumul is probably the most common type of archaeological object covering Europe, where Timutudar will identify the Atlantic, Nordic, Central, Mediterranean and Eastern European Barrels regions. The results I would like to share with you are connected with my country of the region, Republic of Moldova, which is part of the last one, Eastern European Zone. This study I started together with our national agency for archaeology of Moldova and the main task was the monitoring of the Barrel Mounds of Moldova of the region for further protection. Then I expanded the area of research to have more relevant picture and now the area of study is limited to the territory of so-called historical Bessarabia or Northwest Pontic region and is located between Danube, Brut and Nista rivers. It consists of western part of Republic of Moldova and Odessa region of Ukraine. It is known that the earliest Barrels appear first of all in the zones of close interaction of various cultural communities, so the northwestern Black Sea region is no exception. And being the most western periphery of Pontic-Caspian steppe, northwest coast of Black Sea surrounded by Capitan mountains, Danube river and Black Sea. And this led to the fact that the cultural landscape since early per history was influenced by three main factors. The first one, southeastern European or the Balkans, East European steppe factor and Central European forest steppe or even forest region. Therefore, the area of interest could be treated during the various periods like frontier or contact zone or the territory where the cultures meet, clash and grapple with each other, often in the context of highly asymmetrical relations of power. And all this led to the fact that this territory has become an archaeological condyke or the land of the Barrels. According to my calculations, using various satellite images like Astrodem and Google Earth and others, almost 11,000 of Barrel mountains are located on this territory of Nista-Brut, with about 6,300 on the territory of Republic of Moldova and about 4,400 on the territory of Ukraine. And there are about 2.5 Barrels per 100 square kilometers between Nista-Brut, while the average density of Barrel mountains from Moldova is much lower than the percentage and density of the Ukrainian part. The concentration of Barrels also differs in various regions of Ukraine and Moldova. The maximum density was recorded in southern part, it's obvious because it's steppe, and regions of Moldova and Ukraine. The minimum density is documented in the central part, it's also obvious for us because it's forest zone and is associated with forest zone of so-called Kodri of Moldova. And it's clearly seen that the Barrel mountains generally follow a linear pattern and are stretched in lines up to 20 or even 30 kilometers long and are closely related to the relief located on the ridges, watersheds, high plateaus along the rivers. Of course, it is impossible to understand how the territory surrounding Barrel mountains or Barrel grounds is arranged without explaining the role of the Barrels in the ancient landscape. And on the one hand, the Barrel Mount or the Barrel itself could be considered as a social and cultural marker, indicating the presence of cultural communities and the boundaries of these communities. And on the other hand, the reuse of mountains, the expansion of these Barrel lines in following periods by other cultural communities gave the Barrel centers an active mnemonic role in the landscape. The linear nature of the patterns along which the Barrels were constructed doesn't exclude the probable connection with the ancient roads marking probably the roots of migrations or season migrations. And for the study of the plenography of Barrel centers, a sort of cities of debt may also reveal some urban patterns for the communities which did not create long-term settlements. And most of Barrel mountains excavated in the research area are up to 100 meters diameter with an average size of 36 meter. And more than three quarters of all excavated Barrels were constructed once. 13% have the second construction level, 6% have the third, 3% the fourth. A small number of Barrels have five construction levels and there is one exceptional case with seven construction levels. And on average the number of Barrels in one mound is about seven in two-thirds of the excavated mounds. In two-thirds of excavated mounds is the number of documented graves is about 10. There are at least 10 Barrels without any Barrels. Apparently if they were built in Roman period in so called Samatian period and probably for other ritual purposes. More than 30 Barrels in one Barrel were recorded on the Lowered Nester, it's also steppe region. But the biggest number comes from the southern part of Moldova, but the biggest number comes from Ukraine. So an exceptional example was recorded on the Lowered Nester of Ukrainian part. It's 163 graves fixed in one Barrel, you see it's number 14, it's Mologe Barrel ground, Barrel number two. The practice of erecting Barrels in our region in the north-west Pontic area appeared probably not later than in 3900s. In 3800 BC or even earlier in 5th millennium BC. Later the Barrel became an important part of the funeral practice of the various communities. Bronze Age, Iron Age, Roman period, Middle Ages and even in modern period of 18th, 19th century AD. And by the way some of the Barrels are still in use in Moldova because you could see some examples of the first one is monument of the Soviet soldiers. The second one is the music festival around probably the biggest Barrel in Moldova. And the third is a modern cemetery, modern Moldavian cemetery in modern Moldavian village, which lies on the Barrel. Yeah, it's about contemporary use of Barrels. Anyway, we have data on about 400 Barrels excavated on the right-bank territory of Moldova and about 400 Barrels for the territory of Ukraine. So the total number is about 780 of the Barrels. So if we compare to my previous calculations that's less than 7% of excavated Barrels. And according to my data, 2% of Barrel mounts are associated with the initial Neolithic period. Almost a half belong to early Bronze Age and about 10% to the late Bronze Age. The Iron Age including the Perseven and Sermetian periods is less than 3%. Later the number of funeral compensates increases in Roman time. It's about 7% in Middle Ages, about 11%. But it should be noted that at least 10% or 290 graves due to the absence of grave boots or some characteristic signs remain unidentified both culturally and chronologically. And most of the Barrel mounts, about 40%, belong to so-called Yamna or pit grave culture of early Bronze Age. But Yamna leads not only in the absolute number of the graves, but also in its chronological density. Besides the demography, the explanation of this phenomenon probably lies also in the fact that the Barrel was the only Barrel tradition for the Yamna culture. And the proportion of Barrels of other cultures doesn't exceed 10%. The late medieval nomads take the second place with 12%. The third with 8% goes to Middle Bronze Age, followed by Sermetians with 7%, and Catacombs culture of early Bronze Age with also 7%. And the statistics regarding to the primary Barrel slightly differs. And at least two cases are known when the Barrels were constructed into a natural feature, like natural hill, the feature of natural region. And at least 20 cases that the primary Barrel was impossible to identify. But the number of Barrels constructed in the inolithic period is bigger. The proportion of the primary Barrels of the early Bronze Age is also higher compared to the secondary Barrels. It's about 60% more than half. But in the middle, Bronze and late Bronze Age is lower. So the percentage of the primary Barrels for the Iron Age is about 7. Roman time is also 7 and is higher in comparison with secondary Graves. And the bulk of Barrels was erected by the Barrels of Yamna culture. So it's about 56% forward by a wide margin. The Sermetians with 8% and Sivians about 5%. And other communities like Late Bronze Age or Middle Bronze Age doesn't exceed 3%. Thus, we could allocate two main periods of the construction of the Barrel Mountains. The early Bronze Age and the so-called Sivian-Sarmatian period. Anyway, it should be noted that the Barrel activity of the Sivians and Sarmatians is noticeably lower compared to the early Bronze Age. Well, the preliminary data on the moundscape of the territory between Danube, Root and Nister rivers show the exceptional unevenness of the Barrel distribution, chronological, cultural and, of course, spatial one. The next steps of this research are to exemplify how the funeral landscape of the Nord-West Pontic area was organized to reveal the patterns in the construction of the Barrels and using them later by other communities. Or, in other words, how the prehistoric and proto-historic communities shaped the natural landscape according to the ideological beliefs and how the very idea of tumulus was changing during the existence of this cultural practice. Thank you.
