 I'm going to talk also on behalf of my colleague clearly. Thank you. Who is actually the person who is following all the technical procedures and analytical methods. And together, we are clearly trying to make the archaeological frame of the work. But our project, I presume there isn't a quicker way of making it work, but in any case, we started almost 20 years ago, in the late 1990s, with a project which was the first one in Northern Italy, which saw the collaboration of geologists, petrographers, and archaeologists. Actually, it was led by a petrographer, Claudio D'Amico. And it was aimed to try to identify the sources of raw materials, greenstone aromaterials, and analyze the circulation of all these materials in Northern Italy. Our region, which is Friuli Venezia Giudia, it is the northeastern region of Italy. It is ahead of the so-called Caputadria. Was interested in the project because there is a, OK, let me check without, OK. Sorry, I go on this way. There is a particular site, a Neolithic site, San Mardenchia, which is extremely rich in greenstone. It is certainly a farming village, with quite a lot of radiocarbon dates, indicating a rather long life from the middle of the 6th to the middle of the 5th millennium. Unfortunately, well, they have basically pits. They have been studied largely. But unfortunately, almost all the greenstone come from surface surveys, and not from these pits. So I want to point one of the first problems of this site. Many extensive analysis, because almost all the pieces, nearly 300, were all analyzed with both non-destructive and destructive techniques. But the correlation between the materials and the dates is still very difficult. In any case, it was possible already in this part of the project to identify the main source, which is in the northwest part of northern Italy. Piedmont and Liguria, an area which then was largely studied also by Pierre Petraken and his team. Not all the materials of the site of San Mardenchia, in any case, come from there. There are many local, presumably local, rocks used. And the point is, one of the point is, we have a length of time of over a millennium. We have a high number of artifacts which are mainly access. There are also some bracelets and other items. But stone axes are the prevailing artifacts. So how did they come? Mediated by other cultures of what for us is the early Neolithic, probably this is the right quest, the right answer. This area in the central poplain, the furano, which had the furano culture, contemporary to San Mardenchia in the second half of the sixth millennium, might have been the connecting area also because we have many pots, ceramic items in San Mardenchia which are very similar to those in furano. But in any case, how did they come? How many times? We don't know, actually, but I just wanted to put a problem on the table. At that time, I mean the end of the 1990s, our part, the easternmost part, the karst, where I work, actually, I am Federico, basically work, was a void, as you can see. Because at the time of the project, we worked on shaft hole axes. So basically, copper age, basically, but not only copper age in any case. The materials from San Mardenchia, some of the materials from San Mardenchia, were actually studied later on, also by the hip hop, Pierre Petra Cana, within his very big project. The technique was different. It was a spectral geometry. The results were almost the same. Well, at least those of you who work on the European Greenstone problems know that within his project, Petra Cana was able to create a typology. But it was a typology, basically, on longer x-hats. It has longer than 13.5 centimeters. And I think that this may be a problem when you try to include also materials which are different and are shorter, and presumably have functional destination into this typology, which is basically created, as I said, for a long axis with presumably prestige value. A chrono typology which spans almost three millennia from the sixth onwards. And allowed the colleagues to create this map of distribution where you can see that Greenstone, basically, jade, non-facide, high pressure metallurgy lights, coming from especially two sources in Chiedmon and Liguria, Montbiso and Beigua, were distributed all around the western part of Europe, already in the sixth millennium and then in the fifth millennium. But they occupied, basically, the western part with few exceptions, especially few items that maybe you can see here along the eastern Adriatic coast, the northern eastern Adriatic coast, where few objects, really long axes, were found. And I stress this item, which is on the Kirk Island in northern Croatia, because I will resume it later. It was found in a place out of context. Many of these in our region and in this part, at least in this part of Europe, have been found out of context. But the Kirk Island is an island where, till recently, there were saline. This means they were the production of salt. And presumably, that is my hypothesis, I will go back to that later. This might be an attraction for human groups and basically shepherds moving along the coast, in this case. At that time, this method was actually published in 2012. We added more pieces to this part of the European region earlier, because, as I said before, we started working on shaft-to-all axes. But later on, we moved also to x-blade-to-axe heads. And we included the materials from both excavations, new excavations, and also old collections, museum collections. So we basically worked on the Caput Adria region. And we had already included in our study materials coming just from the northern part of the Eastern Adriatic. We tried to put that in context, also working, well, not really working, but considering also materials of other type, especially obsidian. In fact, we have some pieces of obsidian coming from Lipari in all this area, but also some pieces coming from the Cartesian. We will see that that is quite an important point for us. These studies were possible within a new project, which we started in the early 2000s. As I said before, first focused on shaft-to-all axes. And many of them coming from Western Slovenia, and in particular, for quite an important series of sites in the so-called Ljubljana-Skobarje Moors, pile dwellings of the actually fourth and third millennium BC. Nevertheless, also there, blade axes, blade heads were found. And again here, the problem is are they pertaining to those periods, or are actually left over from previous periods? That's a question, clearly, an open question. Then later on, as I said, we included also axe heads, just also the one from the Kirk Island, which is kept in one of the news you mean in Istria. Different sites, different locations, different contexts. And I think this is a very important point to discuss on because the value of sites bears a point, the value of objects, and vice versa. So I think we will try to discuss, I presume also on this later. Within our project, the collaboration of different institutions or of different factors was very important because of the possibility of using traditional methods and using also innovative techniques. The project was made at University of Trieste with the collaboration of the International Center of Theoretical Physics, the multidisciplinary laboratory where Federico works at present, then Eletra Synchrotrone and also the Institute of Archaeology of the Academy of Sciences in Ljubljana. Then others were edited according to where our vertebraes pointed to. As you can see, non-destructive and destructive techniques, I am not a specialist, but if you want, we can try to go again over to these problems later. This collaboration, as I said, this collaboration allowed us to work on both old collections and new excavations one, which was particularly important was that in one of the cave of the karst, actually the Slovene karst, but very closer to the Trieste karst where we have 180 caves with archeological materials and inside some 50 gravestone artifacts, mostly axes, both x-heads and shaft-hole axes. But this cave, in the Slovenian karst, Besta Grodza, was recently discovered and excavated. And dated, which means, as you can see, the second half, well, actually, from 5,700 to almost the end of the sixth century. The point is, it is quite interesting because it is a closed context and it is the one where for the very first time, there was found, well, a drawing, probably. It is strange, but in any case, it is the only one found today. We contribute, also, the axes found in our caves of the Trieste karst were studied, but not all of them, so we still have problems, but one of the problems is not only of identifying the provenance of the rock, but it is also that of understanding the meaning of finding stone axes within caves. I heard before that there are other situations. It will be quite interesting to understand why because certainly, in caves, these axes cannot have a functional use. So in our project, we also identified the sources which are different from the most commonly known high-pressure metamorpholites from Northwestern Italy. And these pieces are much fewer in comparison, but indicate quite different directions of provenance. In particular, we have a few, really few, three, four shoelace axes. They are made, three of them are made from fine grain, green-chloro-colored cryptocrystalline rocks, and the possible area of provenance in the Vicarigian in Croatia, where there is also an area of production. An area of production has been identified, but probably the provenance was mediated, the movement was mediated by Dalmatia, because also there are some finds, similar finds. In one of the caves of the Trieste Castle, we have a very similar, from the typological point of view, object, but clearly in a different rock. And that piece was associated with one single piece of a carnation, obsidian. So, mixed influences clearly, already in the sixth millennium, and also continuing in the fifth millennium. And in particular, already in the fifth, half of the fifth millennium, we have some shoelace axes made from northern Bohemian betabasites, again found in few pieces, but identified through careful analytical methods. So, we are sure about the provenance. And these provenance have made us hypothesized that there might have been, during already in the sixth and certainly in the fifth millennium, we see two basic areas of use of different sources of, let us call it, greenstone in brackets. So, the Western Europe were clearly jade from the Alpine sources that we veiled, and an Eastern area were, on the contrary, Bohemian metabasites were largely produced and distributed there. So, if you want to conclude by saying that we also have clearly to think about a cultural interpretation of all these situations, we must ask why and one possibility would be for all these movements coming from different areas that pastoralism was, which had been identified in, especially in caste caves, was responsible for all these movements. And as I said before, probably also natural salt availability, because we have some materials already in the sixth millennium, which would allow us to at least put forward these apotheosities. Thank you for your attention.
