 So my time period is Mycenae in Greece. This is right around the time of the famous late Bronze Age collapse. So everything is kind of going to hell at this point. The palaces have already been burned down in the archipelago, which you can see up here. So the famous site of Mycenae. I work primarily in the Northwestern Hulipanis in Achaia. At cemeteries that span about 600 years of use, most of the rock cocktails are used quite late, and they're cleaned thoroughly. So it's only by a stroke of luck that we know that they were built early from chance finds and secondary use bits. But essentially what I do is I do photogrammetric modeling and energetics modeling after the methodology from Elliot Abrams updated slightly into a more comparative format. So I use a range of rates since we can never know how long it takes somebody to build something. Humans move at a fairly average rate, depending on the material. So if you know vaguely your tools, the material you're cutting into, and the amount of material being moved, you can make an educated guess as to how long it took to build something. But if you're uncomfortable with energetics, that's fine. You can also just use volumetrics, which with photogrammetry you go in there and you take a bunch of photos. They're geo-referenced with the total station. We're too cheap for a 3D scanner. Although if you have a 3D scanner, it's much easier to just do that. But anyway, this is a relatively inexpensive way to preserve the tombs. And I'll get down to the two models themselves. So you can see the cemeteries there. Wudni, there's estimated about 150 tombs, 80 which have been excavated over the last century. Most of them follow this beehive pattern. So these are not the famous tolos tombs, although I did do a tolos tomb near Athens that are built tombs. So short upward rock. These are strictly rock cuts into the local, they call it marl, but it's chamelea. It's a very soft limestone, very friable. You can almost scratch it with your hands if you wanted to. But in any case, they had a very set idea of how these tombs should look like. Bearing in mind, these tombs are closed most of the time or so we think. So the entrance pastures over here always wedge shaped, but filled in to where you cannot see them in line with the slope. So you can't see them until either somebody takes them up or the roof collapses of the chamber and opens a hole. So some of these, the roof did collapse and they were reconstructed slightly, but you can see the differences in scale here. So the Manini tolos, this one is not rock cut, but rock built, 22 times the size of the median. So somebody very important was buried here. We can't really call him a king, but someone near Athens, not necessarily a part of the late Bronze Age Athens, but certainly within on their radar as a person of interest. But so my trick is to just take the volumetric measurements and plug them into SPSS just to try to see what kind of spatial patterns because all of these tombs are empty by the time that I get to them. I have no solid chronological data. Most of our chronology is built on ceramic phases that last several centuries. Whereas I argue that these tombs are built in a matter of days, essentially. Even the largest ones, they don't take really more than a month to build if they're building these as quickly as possible. So, which I imagine for a tomb, that's essentially what you're doing. But the numbers up there are meaningless. They're just a relative index. So I played around with it and just used the playful eye catching phrase T-Rex. No better controversial scale than for an archeological conference to use an actual T-Rex. But yeah, essentially the trick is flattening out the measurements, taking your medians across 12 different dimensions. So it's a tri-part type thing. You take each to its own. The dromos, the stomium, the threshold which is blocked with usually river stones and the burial chamber itself. More often than not, the remains are just left on the floor or dug into pits. But the colors, red, it's mirrored across the diagonal. So really only needs one half of that. But the red means that they're very close in measurements. And these are tombs spread out over hundreds of kilometers or hundreds of years. So the argument is that they're not looking at these things and they're not measuring them. But they're building them from a set, a cultural ideal of how a tomb should look like. So it's a mechanism of collective memory that I use in the manner of Paul Connerton and the memory studies of the late 90s, early 2000s. So trying to bring that back a little bit but also diving a bit deeper into the psychology of it. So yeah, that's essentially it. And if you want to read more in-depth on it, I don't want to cut into your coffee break here. So just send me an email. I use my old email address up there but I'm affiliated with Leiden University in the Netherlands. And we're an ERC funded project and there are several PhDs that are finishing up this year based not only on the tombs, which is what I work on, but also on the fortifications and on the settlements themselves, how people lived. So we're studying how people lived and how they died during the late Bronze Age. Thank you.
