Performing XRD analysis on Nile clay Nubian- and Egyptian-style samples from Attab and Ginis

Exams never end, not just for humans but even for archaeological artifacts.

Already before the Christmas break, I had happily returned to the lab, this time to prepare a new bunch of ceramic samples to undergo X-ray powder diffraction (XRPD) analysis. Thanks to a new cooperation with the TU München, and especially with Prof. H. A. Gilg (Chair of Engineering Geology) we decided in fact to complement our iNAA and OM analyses with this new laboratory methodology, with the aim of expanding our knowledge on the composition, provenance and technology of production of our Nile clay samples. All in all, we preliminary selected 30 ceramic specimens, among Nubian- and Egyptian-style sherds from the 2022 and 2023 excavated sites at Attab West and Ginis East. To this sample, we added a replica in modern Nubian (from Abri) Nile clay manufactured by us during our last workshop in Asparn.

Generally speaking, X-ray powder diffraction analysis is a well consolidated analytical technique used in the field of archaeometry and ceramic technology to determine the mineral phases present in the pastes, including those clay phases which are typically not visible under the microscope. This technique also provides information on the firing process the pottery went through. Certain minerals (e.g., calcite as one of the most known) can in fact degrade, disappear or be altered at given temperatures because the crystalline structure collapses through the process of dehydroxylation (Magetti 1982; Rice 1987). The analysis itself based on the phenomenon of diffraction of electromagnetic radiation, by exploiting the fact that X-rays falling on crystalline planes in minerals are reflected at varying angles (Velde and Druc 1999; Quin 2013). Hence, each mineral type will produce a characteristic X-ray diffraction spectrum with diagnostic peaks placed at given angular distances (expressed in degrees 2θ), allowing the qualitative identification of the minerals present within the ceramic sample. The heigh of those picks permits otherwise a semi-quantitative estimation of the ratios in which minerals are more or less represented.

Sample preparation is pretty much straightforward although partially destructive. The procedure requires that a tiny portion of the sherd be ground up (about 1g of powder) by hands with an agate mortar and a pestle, alike those used for iNAA, pressed in the mounting smear slide, and then put into the instrument. Proper pulverization and homogenization are crucial to achieve highly quality XRD data.

The sample needs to be as representative of the ceramic sherd as possible – for this reason, it is sometimes advisable to grind a larger quantity of powder and above all finely ground so as to prevent larger crystals (e.g., coarse quartz grains) from interfering with the measurement. This latter can be carried out with different timing and levels of accuracy depending on whether one wants only a rough semi-quantitative estimate of the mineral phases in the sample or more accurate information.

In performing XRD analysis, our main archaeological questions were the following:

  • Can we recognize the use of different clay raw materials for the different sites/locations (e.g., Attab, Ginis…);
  • Can we differentiate between Nubian- (also Pan-Grave) vs. Egyptian-style samples;
  • Can we differentiate between the different ceramic types and wares;
  • Can we demonstrate the intentional addition of tempers (calcite and/or quartz and/or feldspar and/or mica) in particular samples?
  • Can we know more about the firing process (i.e., firing temperatures) the ceramics went through?

Currently, together with Prof. Gilg, we just started to interpret the results of the first diffractograms. The data are not always straightforward to read and the differences between the various samples look sometimes very subtle – on the other hand our Nile clay samples have used us to significant challenges for many years already!

Preliminary, we can say that, based on the diagnostic mineral phases in the various spectra, it was possible to recognise four distinct groups or types of samples. These groups do not depend on the main phases (quartz or feldspar) as these are present in nearly homogenous amounts in all samples. Rather, some differences can be spotted in the clay minerals. Whether these latter can be ascribed to different clay sources, preparation recipes, or eventually the pot production (i.e., firing) has yet to be fully assessed.

Now published: our excavation report 2023

Perfect timing – just before the holidays, the new issue of Der antike Sudan – Mitteilungen der Sudanarchäologischen Gesellschaft zu Berlin e.V. arrived in our office, hot off the press. It comprises a broad range of topics, including our 2023 excavation report.

Chloë, Kate and I summarised under the title “Cultural diversity in the Bronze Age in the Attab to Ferka region: new results based on excavations in 2023” the most important working steps and results of our field season in Attab and Ginis earlier this year. This work would not have been possible without our Sudanese workmen and the support of all authorities. We are in particular very grateful to Huda Magzoub Elbashir, our NCAM inspector and long-time collaborator and friend.

An update of our work in Kerma cemetery GiE 003 can be found in the article, highlighting the relevance of the Pan-Grave burials we discovered in Trench 5. The presence of cultural diversity (Pan-Grave Nubians, Kerma Nubians) and evidence for cultural exchange (with the Hyksos – see for example the royal scarab, with the Egyptians – especially through imported ceramics) is of key importance for the ERC DiverseNile Project.

Furthermore, a short section describes our work at site 2-S-54 which we recorded as AtW 002. The rectangular Structure 1 on this site can be dated through the ceramics to the early 18th Dynasty and I included in the new article the results from the C14 analysis of a charcoal sample from a fireplace in the lower stratum, presumably the primary usage horizon. The sample yielded with the highest probability the period of 1688-1517 BCE, supporting our hypothesis that AtW 002 and neighbouring sites were probably used from Classic Kerma times to the early New Kingdom. The site is located along a paleochannel which was documented in our 2023 season by Kate (who also describes her work in this article). This paleochannel was recently addressed by our colleagues Mat Dalton, Neal Spencer and others (Dalton et al. 2023) under the topic of the intriguing river walls (of which there are plenty in our concession).

The report includes an update on our 2023 excavation at AtW 001 which allows a better understanding of this site, also in terms of dating. The material found in the debris layers we excavated in 2023 is all mid-18th Dynasty in date, therefore an abandonment of the site under the late years of Thutmose III or one of the subsequent Egyptian kings is likely. The latest pottery found at the site seems to date to the reigns of Amenhotep II/Thutmose IV (e.g. imported bichrome decorated ware).

Finally, Kate describes in the article the two primary objectives carried out for the landscape work package during the 2023 field season: 1) the drone survey over the entire district of Attab West and other areas in the concession, including low flights over selected sites for the creation of detailed orthophotos and digital elevation models of the terrain, and 2) ground survey and mapping of dry-stone features in the landscape, using a Trimble Catalyst GPS receiver, and a TDC 6000 data collector. One of Kate’s nice drone photos also made it to the cover of the new issue of MittSAG!

Seeing results of our fieldwork in Sudan published is very ambivalent at the moment – it reminds us all too well of our friends and colleagues on site and the terrible situation in Sudan, which unfortunately continues to escalate. The hope remains that 2024 will bring rapid improvement for the country and its residents. Just as there will hopefully be peace in other parts of the world.

New dissemination article about our 2023 season

With all the snow here in Munich, it is quite a good timing to see the new volume of the Project Repository Journal going live. It includes a new dissemination article about our season in Sudan earlier this year.

Check it out if you want to know more about our works at sites like the Kerma cemetery GiE 003, the domestic site AtW 002 along the major paleochannel in Attab West dating to the early New Kingdom and the larger New Kingdom settlement site AtW 001 which was located on a former island, close to the present Nile on the west bank of Attab.

As much as it is a joy to see such an outreach of our project, we are widely concerned about the risks the people and the cultural heritage of Sudan are currently facing – may this terrible war end soon. Hoping that peace will come as soon as possible, our thoughts are with all of our friends and colleagues.

Upcoming DiverseNile Seminar: how to conceptualise narratives of Napatan shabtis figurines using 3D print replicas

I am excited to announce the next DiverseNile Seminar for Tuesday, 5 December. Amanda Ford Spora will talk about her research with replicas of Napatan shabti figurines.

Amanda is currently a PhD candidate at the University College London. She is a community archaeologist with fieldwork experience in Sudan, especially at Mograt Island.

Her exciting research is “about co-creative meaning making using digitally produced replicas, and the process that non-professionals and professionals engage with together, to manifest authentic narratives of the ancient past.” The shabti figurines she is using for this include Napatan shabtis, of which the originals are currently in the UK. Amanda has undertaken research with teenagers in Sudan, Australia and United Kingdom, last but not least also to raise more awareness of the rich and endangered Sudanese heritage.

Her research fits perfectly into the agenda of the ERC DiverseNile project – as Kate Rose outlined in a previous blog post, we are also using the rich potential of 3D printing ancient artifacts. We are in particular interested in the implications these replicas hold for education and outreach, the accessibility of archaeological heritage, and explorations in experimental archaeology.

Speaking about education, I would once more like to advertise the fantastic recent volume “African Archaeology in Support of School Learning” – these contributions and also the splendid introduction are very inspiring and underline the wide-ranging relevance of our research (see also our article on the reconstruction of lived experiences in Sai City during the New Kingdom).

However, we must not forget the current challenges of school education in Sudan after more than 7 months of war. With an estimated 19 million children out of school, the country is facing a major education crisis. In a recent blog post, solutions to revive the education sector were proposed – I heartfully wish that the wonderful and amazingly resilient people of Sudan will achieve the revival of their educational sector by means of collaborative efforts. For this, they should receive as much international support as possible – and maybe also archaeology in Sudan and especially community archaeology can help a little bit to overcome this crisis.

Copper alloy production and use: upcoming DiverseNile Seminar

I am delighted that our next DiverseNile Seminar is approaching. Frederik Rademakers will be speaking about brand-new research on copper production in the New Kingdom.

Frederik is currently employed at the British Museum, Department of Scientific Research as a metals specialist. His core research focus lies on ancient copper metallurgy in the Nile Valley and central Africa. Frederik’s approach is a combination of analytical studies of archaeological remains (from museum collections as well as ongoing excavations, e.g. Kerma and Amara West in Sudan) and experimental archaeology. Through the latter, we have been frequently in contact in the last years, and I can very highly recommend his seminal publications, e.g. Rademakers et al. 2022.

I am especially happy that the upcoming presentation by Frederik on November 21, 2023 will nicely connect to our previous DiverseNile Seminar 2022, focusing on landscape and resource management. In general, the procurement of materials and management of resources are topics which have gained popularity in archaeology in recent years, also in Egyptian and Sudanese archaeology. Modern multidisciplinary approaches enable us to investigate objects’ complete chaîne opératoire. An excellent example for these new advances is the study of copper in Egypt and Nubia (see Odler 2023) and in particular copper production at Kerma, a topic Frederic is an expert in (Rademakers et al. 2022). From the New Kingdom town of Amara West, a recent study in which Frederik was one of the main persons involved has provided important insights into the complexity of production chains, the question of material availability and supply in colonial Nubia and the direct comparison with Egypt (Rademakers et al. 2023).

In the upcoming DiverseNile Seminar, Fredrik will discuss unpublished material and data for the New Kingdom – nothing you want to miss if you are interested in archaeometry, copper production and interdisciplinary approaches to the topic.

One paper out, a new exciting Raman spin-off project just launched

About two years ago, at the height of the Covid pandemic, the idea was born to initiate a scientific cooperation with our colleagues Fabian Dellefant and Melanie Kaliwoda from the Department of Earth and Environmental Sciences of the LMU and test together a new analytical methodology for archaeological ceramic material, namely Raman Spectroscopy.

Specifically, we aimed to first perform Raman spectroscopy towards carbon-bearing pottery and yields insights on the application of this technique for estimating maximum firing temperatures of Late Bronze Age vessels from Upper Nubia, comparing two site-specific data sets of samples, from the 18th Dynasty (1550–1290 BCE) at Sai Island and Dukki Gel (Kerma).

The encounter between natural sciences and archaeology was successful and from this idea an inspiring project developed, culminating in the publication of the paper: “Differentiation of Late Bronze Age Nubian- and Egyptian-style ceramics from northern Sudan by manufacturing firing temperatures using Raman spectroscopy”, in Journal of Archaeological Science: Reports, as part of the Special Issue Materiality of Earth edited by Pamela Fragnoli, Elisa Boccalon, Susanna Cereda, and Giovanna Liberotti, whom we all deeply thank for inviting us to contribute to this SI.

In testing Raman spectroscopy, our principal aims were to search for differences in producing technique and firing temperatures between the Nubian- and Egyptian-style samples; between the samples from Sai Island and those from Dukki Gel; and eventually among the different ceramic wares and types.

Now, as it is often the case, one idea leads to another and while some of the archaeological questions posed in the initial objectives of the work have not yet been fully answered, new exciting questions have arisen during the research and led us to further expand our Raman project into a new spin-off project focused on the investigation of the effects of oxidative weathering in relation to site-specific depositional environment and time.

Generally speaking, oxidative weathering is known to cause significant alteration modifications of the ceramic body after deposition resulting in distorting Raman spectra and potentially leading to an overestimation of the firing temperatures (Deldicque et al., 2023). Although all archaeological ceramics experienced oxidative weathering, our case study showed that the weathering effect was possibly more intense on the Dukki Gel than on the Sai Island samples hence to affect maximum firing conditions.

The new set of samples for which thin-sections were produced to perform Raman Spectroscopy.

In the coming months, together with Fabian Dellefant, we will particularly focus on this aspect of our research and perform Raman Spectroscopy on new samples, including ceramic sherds that have undergone extremely intensive oxidative weathering and experimental replica which were never exposed to any depositional and post-depositional processes.

Stay tuned to know more about the development of our work!

In focus: Jebel Barkal and Kushite urban sites

Today, winter term has started in Munich and another DiverseNile Seminar is approaching.

Although we are still very concerned about the current situation in Sudan, with the terrible conflict ongoing since more than 6 months, threatening and endangering civilians and also cultural heritage, we are delighted to host our next event dedicated to Sudanese archaeology.

Tomorrow’s speaker will be Geoff Emberling, Associate Research Scientist of the Kelsey Museum at the University of Michigan.

Geoff is well known for his comparative perspectives on ancient cities, states, empires, and ethnicity. Originally a Near Eastern Archaeologist by training, he has conducted fieldwork in Sudan since 2007 and has become an internationally renowned expert on the Kerma period and the Naptan empire.

His talk for the DiverseNile Seminar will give insights into his current project at one of the most impressive landmarks of Sudan: Jebel Barkal. This holy mountain has an amazing history throughout the ages and the site incorporates temples, pyramids and palaces. The Jebel Barkal Archaeological Project (JBAP), co-directed by Geoff and El-Hassan Ahmed Mohamed, started its work in 2016. This new project aims to unearth Jebel Barkal as an ancient city—the “lost city” of Napata, the urban backbone of all the known palaces and temples.

I am very much looking forward to hear more about the latest research at a fascinating site in Sudan. Although Jebel Barkal and questions about Kushite capital cities are beyond our DiverseNile Bronze Age perspectives, this case study has much potential to address crucial questions about urban sites, their infrastructure, organization and hinterland.

Digitally Documenting a Fortified Islamic House in Attab East

This past season in Sudan, our drone program took flight (pun-intended) in more ways than one. We dedicated most of our efforts to flying programmed missions over large areas of the landscape mainly in Attab West, to collect data for the generation of Digital Elevation Models (DEMs) and orthophotos. In addition, we found time to make targeted flights of standing architecture for 3D modeling and visualization purposes. Digital recording of archaeological sites using the methods and principles of photogrammetry has immense implications for cultural heritage preservation.

I was able to spend an entire day in Attab East documenting an extremely interesting, and remarkably well-preserved Islamic house, located just south of the Nile. The structure was identified and recorded by André Vila as site 2-S-57, a fortified Islamic house. It was built on a small raised rocky plateau, east of a small drainage channel.  

Image of the Islamic house 3D model in Drone2Map, facing north.

The house is especially interesting in that many of its walls are still very well preserved, along with evidence of a second story, multiple small staircases, and a larger staircase in the northwestern corner of the house, leading to a tower-like structure. Several walls have also collapsed in recent years, and the collapsed building material remains in situ in the southeastern corner of the structure.

The house itself is designed with a large central courtyard surrounded by relatively small interior rooms. These rooms are all roughly rectangular in shape, seem to be similar sizes, and are mostly oriented east to west. Some rooms contain interior sub-divisions, as well as windows and doorways preserved along the northern exterior wall. The rooms form a cellular pattern around the central courtyard, a common architectural pattern in Islamic houses (Abu-Lughod 1987; Petruccioli 2008; Zolfagharkhani and Ostwald 2021). It would certainly be interesting to consider the use of domestic space in this house, as activity areas and movement patterns are surely present.

Current challenges exist to the house’s preservation, including erosion, flooding, and modern use of the house’s rooms as animal pens. It is interesting that there is continuity in the use of this structure for subsistence activities. However, it is extremely important to have the opportunity to digitally document well-preserved, at-risk sites such as this one. I collected approximately 700 images using our Phantom 4 drone of the site and processed a 3D model in Drone2Map.

Given the high-quality model, the site can be virtually “visited” on open-access sites like Sketchfab. This gives diverse publics the opportunity to engage with and experience the site. Furthermore, systematic analyses such as space syntax can be conducted to further understand the use of the site with the data from the model. Digital representations of archaeological sites are especially valuable during periods of political turmoil when cultural heritage may come under threat. Given the on-going conflict and humanitarian crisis in Sudan, and the enduring impact of the Covid 19 pandemic on research disciplines in general, archaeologists must continue to develop innovative solutions to critical problems of cultural heritage management and preservation.

Check out the model of the Islamic house for yourself on MUAFS’s Sketchfab profile:

Here you can play with the model, manipulate the view, zoom in on rooms and features, and experiment with the size of the model. Sketchfab is a completely free educational platform for all users. Be on the lookout for more models from the project in the future!

A day on the Nile – new approaches to reconstruct lived experiences

I am very pleased that an article I prepared together with Chloe Ward and Carl Elkins as part of a forthcoming special volume of the journal African Archaeological Review dedicated to “African Archaeology in Support of School Learning” (see Stahl et al. 2023) is now published. This manuscript was shaped over more than one year and was extreme fun to write.

Back in 2022, Ann Stahl asked me whether I would be willing to join this project preparing an unusual publication as a tool for schoolteachers and students rather than a scientific article. I was immediately excited, especially since I had already some experience teaching at schools in Austria and Germany. But this was different – more hands-on, more research-related and a very collaborative process with wonderful colleagues and a fully motivated working group. It was also a real challenge and new experience.

Since some years, I already had the idea to write a children’s book from the perspective of a dog experiencing life in an Egyptian town in Nubia in the Second Millennium BCE. Within the AcrossBorders project, we found in 2015 this cute dog figurine in the New Kingdom town of Sai Island.

We aimed for a different perspective in our article, focusing on object biographies, narratives and story telling. „Wastl“, the dog figurine from Sai Island, was a key figure here.

Well – this was the starting point and inspired me to propose the blending of a fictional narrative with factual archaeological evidence for our contribution to Ann’s volume. Together, we developed and offered an interpretation of what a typical day may have been like living at Sai. We created a small girl letting us have a look into her life and daily routine. Of course, this girl is a proud dog owner – but check out our story for more!

In our contribution, we also offer explanations for how archaeologists work and interpret some of the evidence we discuss, focusing on a range of methods. These include recent advances in virtual 3D reconstruction which offer a unique perspective on our interpretation of the past. Carl created magical photorealistic and interactive 3D models – these are not only a great outcome themselves, but also allowed us to come up with new interpretations and asking new and different questions. The corresponding figures we included in the article were taken directly from within the interactive virtual reconstruction created in real time.

Construction material has been added for a hypothetical renovation, which was known to occur regularly in domestic contexts. As research is ongoing, the geometry and texture of the buildings’ façades are simplified. Image: Carl G. Elkins

Although we focus on the past, many of the aspects we discuss in the article are highly relevant today and can be linked to several of the UN Sustainable Development Goals (in particular 9, 11, and 12). We encourage readers to think about some of the things we discuss in relation to their own lives and experiences and have provided a number of call-out questions in speech bubbles throughout the article to get some of these discussions started.

As soon as the complete special issue of AAR 40, 3 will be published, there will be the link to some supplementary material which will allow to explore the reconstruction of Sai city in an interactive mode. We are very much looking forward to any responses – from our fellow academics as well as of course schoolteachers, students and other people interested in archaeology and the relevance of the field for us nowadays (and in the future). In the meantime, we will be busy exploring more scientific questions that arose from the photorealistic virtual reconstructions – and there is quite a number of exciting ones.

Experimental use of so-called fire dogs: Asparn/Zaya 2023, part 2

It’s been a few weeks since our fantastic weekend full of experimental archaeology at Asparn (Austria), at the MAMUZ museum. I have tried to summarise the first part of our experiments, producing Nile clay vessels including the firing process with animal dung, in a previous blog post.

Once again, loads of thanks go to all our dear friends and colleagues who supported us – Vera Albustin, Ludwig Albustin, Michaela Zavadil and Su Gütter – as well as to the Viennese hosts of the event, especially to Mathias Mehofer.

Part of our 2023 team experimenting with Nile clay, animal dung and fire dogs (photo: M. Mehofer).

The second part of our experiments was dedicated to cooking with fire dogs – a topic which keeps us busy ever since our work at Sai Island and the discovery of large amounts of fire dogs in the New Kingdom town. We have produced a number of replicas of fire dogs in the last years – and have tested various settings and arrangements of fire dogs to hold a cooking pot above the fire.

Our 2023 arrangment: two fire dogs (here with handles instead of snouts) holding a Nubian-style cooking pot.

This year, we tested a new arrangement – placing two fire dogs in our pit to hold a Nubian-style cooking pot. Other than normally reconstructed (following a seminal paper by D.A. Aston), we placed the fire dogs upside down – with the “ears” to the top, using these as support for the pot.

Detail of our 2023 arrangement with the cooking pot supported by the „ears“ of the fire dogs.

Well – the preparation of red lentils was absolutely problem-free – we used some wood as fuel as well as cattle dung. The fire dogs held the pot next to the fire, allowing us to reduce or increase the temperatures upon need.

In progress: preparing red lentils in our Nubian-style cooking pot placed on two fire dogs (photo: E. Schuster).

Our replicas of fire dogs include examples with “snouts” as well as with “handles”, just like the Sai originals. For our cooking experiment this year, we used two examples with handles and placed the handle away from the fireplace. And: at the end of the cooking process, we could use the handles to take the fire dogs straight out of the fireplace and use them as a support for the pot while we were eating. Could this maybe be the explanation for these parts of our curious fire dogs?

The end of a sucessful experiment: we all enjoyed our meal and the cooking pot was held by the same fire dogs we has just used in the fireplace.

We will continue to experiment with our fire dog replicas – not least because one of our new settlement sites in the MUAFS concession in Sudan, AtW 001, yielded several fire dogs from 18th Dynasty contexts, providing an excellent fresh parallel for the situation at Sai Island.
