 Ladies and gentlemen, dear colleagues, I'll just go to the start. Together with the rise of the Ernfeld cultures in Bronze Europe, we can see a dominance of cremation as the primary or, well, the general type of burial ritual in large areas of Europe. And in Poland, we have the Lusatian culture, the thing that is traditionally called the Lusatian culture, which is part of this Ernfeld phenomenon. And lower Silesia, which is the southwestern part of Poland, are numerous sites related to this culture. Well, it's settlements and symmetries. So we can see a dense network of sites. And towards the end of the Bronze Age, well, technically it's the early Iron Age. It's the Kalisztat C and D periods, which are dated like this. There is growing diversity. We can observe growing diversity in the burial ritual in Silesia, which is perhaps connected to contacts with the East Kalisztat province. The number of grave goods in these graves becomes larger. Also, the new types of graves appear. So the archaeological record in terms of burial practices becomes more diverse here. And together with Agata here, we explored one of these symmetries, about 30 kilometers south of Prokzwav in the Silesian plain. It was a rescue excavations. There were numerous graves there. And we selected one of these graves for more detailed analysis, gearcheological analysis. Well, the soil background in this area, these are eroded Lusatian soils. They are formed in low S or lowest type sediments mixed with sand. This is the grave during exploration. So we can see a more or less rectangular, rounded rectangular pit, numerous grave goods within the grave. And for these more detailed analysis, we selected the urn and the company vessel. They were well preserved. That's why we selected this vessel. The urn was our primary goal for these analysis. And what we were trying to do is we were trying to get some answers, some detailed answers, about some details about the Lusatian funerary ritual. This is how we believe the ritual looked like. So the body was placed on a funeral pyre, which was ignited. Then the burning process occurred. And then, well, this is the question. What happened later? Were the bones picked out of the pyre? How were they picked from the pyre? And how were they placed into this ceramic vessel? And again, we wanted to see what's inside one of these accompanying vessels. Are there any signs of organic residue inside in the soil? So these were our two primary research questions here. And this is the method that we use. So we started with a CT scan of both the urn and the accompanying vessel, followed by exploration, layer by layer, connected with sampling during the exploration. And then, well, there's a whole suite of analysis that you can do after this. But right now, I would like to concentrate just on the micromethology here. Well, this list, you can expand this list of analysis, of course. So the CT scans. This is the urn on the top. This is the accompanying vessel here on the positive side. In the urn, you can see clearly the bone deposit. And the bottom and the soil which covered the bone deposit. The accompanying vessel, well, this is more homogenous. But on some of the scans, we could see that there's a different density in the lower part of this vessel, a higher density. I'm very sorry. So the sampling procedure, which we admit is not perfect. So we're still looking for the perfect sampling procedures for such archaeological context, for vessels like this. We inserted an aluminum profile into the urn and into the accompanying vessel. But, well, it's not perfect, as I said. And we lost about half a centimeter of the lowermost part of these infills, which is regrettable. Because, well, we lost some information there, probably. So we inserted the profile, extracted it, and then went on with the impregnation and thin section preparation. OK, so now, to the results, this is a scan of the thin section from the urn. So clearly, you can see the bone deposit here. And the soil which covered it, the bone deposit. It's composed of variously burned bone. You can see the different color. Mixed with soil fragments and some organics there. But what is perhaps most striking is that there are only single charcoal fragments within this bone deposit. And I mean really single, like three or four, which have been observed. And very few microchalk also. The soil fragments are a mixture of probably the old A and B horizons. And all this is very well bioturbated, the whole bone deposit right there. The bones, they show different, well, the temperatures of burning were differently, and the effect of the bones differently. So that's why the bones have different coloring. And when observed in Lula, you can see that the fluorescence of these variously burned bone fragments is also different. So that's also an interesting thing, I think. Same here. And some of the phytoliths, which have also been observed in the bone deposit, seem to have been burned also. But it's a mixture of burned and unburnt phytoliths. You can see also some plant tissue fragments. There were fresh roots also penetrating into this deposit. So it's not necessarily ancient fragments of plant tissues right there. The accompanying vessel fill, when you look at the scan of the pin section, you can see that the portion part here, these lower most two or three centimeters, is slightly different than the upper part. And what we can observe in this lower most part is there seems to be more B horizon type soil fragments here. It's all very granular. You can see that component of soil fragments. Very low biotubated by funnel activity. You can see many channels right there. A lot of roots penetrating into the lower most part. When explored, this vessel, it was covered in a mat of roots. So it was very well penetrated by roots. So yeah, this is the B type soil that we observe here. But there are no signs of translocation. So what we think is that these are just fragments which fell into this vessel. Some coatings in these B type horizon soil fragments, which testify to some of the soil chemistry perhaps, and single fragments of charcoal in the lower most part in the upper most part. But also just single fragments of charcoal, single fragments of bone, also burnt bone. We can see fresh roots penetrating into this part. And also some burnt phytoliths, but also unburned phytoliths, which probably occurred in the soil and just fell into the vessel together with the soil fragments. Yeah, right there. So what we can say right now, these are very preliminary results. But what we can say or try to narrow down these details of the Lusatin culture burial ritual is that there seem to be no remains of the funeral pyre in the urn mixed with the bones, which suggests that the bones were separated from the remains of the funeral pyre somehow, perhaps by flotation. But welcome any ideas here that you might have in this regard. The fact that the bones have a different color testifies to the fact that they have been variously affected by temperature, which probably indicates that the burning episode on the funeral pyre, there were oxygen was somehow limited in some parts of this funeral pyre. Well, when you look at the human body, some bones are better kind of like enclosed in flesh. So perhaps that's it. Some of the bones, which has this has been suggested to us during some microbiomorphological workshops that some bones might show indication of crushing, but in situ crushing, which might indicate that the bones were somehow stuffed into this container, into this ceramic vessel. And regarding the accompanying vessel, well, we don't see any sign of any grave goods there, of any kind of deposit, which might have been considered a grave, of any kind of organic deposit there. So, well, the vessel might have been just empty, or the goods were just not preserved. But this also might be related to our not perfect sampling procedure, which didn't allow us to observe the lower bones part of both these vessels. So still some work to be done there. Well, this method that we suggest that perhaps could be used for studying of such vessels, the integration of microbiology, geochemistry, and botanical analysis, all starting with CT scans, of course. Well, if we look at how the Zachary and Butcher symmetries look like, you can see that sometimes you can identify different zones. And these zones also seem to have some chronological differentiation. So if we sample such graves from different zones, we might be able to track some changes in the burial ritual here on a very microscopic scale. Also, so. That's it. Thank you, Zunjala. Thank you very much.
