An appeal from an archaeologist’s perspective not to forget the situation in Sudan

At the Meroitic conference in Münster in September, all participants approved a statement on the current situation in Sudan. Particularly due to the recent news surrounding the National Museum in Khartoum, other museums and historical sites in Omdurman, but also the damage caused by the heavy rains in August, we as a scientific community are deeply concerned. We also noted that Sudan has unfortunately received very little media attention since the war began – this holds true for almost all countries, including Germany and Austria. I am therefore very grateful that I was interviewed by The Austrian Broadcasting Corporation about Sudan (many thanks for the mediation through the Austrian Academy of Sciences!). The short interview is now online (also available as soundtrack) and may help to clarify a little how much is currently at stake. Even if the recent fighting in the greater Khartoum area gives cause for cautious hope, we must not forget the huge scale of the catastrophe. Sudan needs international attention and help on many levels.

In August 2024, very heavy rains caused much damage in northern Sudan. Here a violent torrent has formed from the mountains and destroyed the asphalt road near Delgo. Screenshot from a video sent by Magzoub Hassan.

Post-flooding irrigation at Attab West in the Bronze or Iron Age – some new data from our drone survey

Back from the very successful International Conference for Meroitic Studies last week in Münster, I would like to elaborate on one interesting site I mentioned there in the broader context of Napatan sites in Ginis West. As outlined in a previous post, presenting these “stone villages”, I took another look at all our drone images and, above all, the georeferenced orthophotos and digital elevation models, especially from Attab West and Ginis West.

This enabled me to correctly locate a site in Attab West, on the border to Ginis West, which I had never found in the field in Sudan. This map of Ginis West was created by Kate Rose in 2023 after our last field season and shows all the Vila sites that we were unable to relocate in the field. There are various reasons for this – some of them are damaged, for some we have problems because of the georeferencing of Vila’s maps and because of unclear terrain on the ground.

Map with the status of 2023 showing sites documented by Vila, but not yet relocated by us in Ginis. 2-T-67 is on the top left, at the border between Attab and Ginis.

The latter holds true for Vila’s site 2-T-67 (Vila 1977, 93-96). I tried twice to relocate it on the ground, but could not find what Vila referred to as channels. I only saw sandy dunes, modern tracks, some depressions, but no clear traces of what Vila described. Since Vila dated these three openings with underground connections to channels to the New Kingdom, based on a single pottery vessel, the site was of greatest interest to DiverseNile. It was correspondingly annoying that I simply couldn’t find the site.

Sketch of the site by Vila 1977: fig. 49 incl. the pottery vessel he used as dating evidence.

However, the dating of Vila is anything but certain. Looking at this pottery bowl, for example, it is more likely to date already from the Pre-Napatan period. The site is nevertheless truly intriguing – the basins and channels have recently been linked to post-flood irrigation by Mathew Dalton and colleagues (2023). They suggest very convincingly that the site, and in particular the circular features, one of which was surrounded by a stone setting, actually served as wellheads for shadufs. Now it was great when I discovered the channels and round depressions on the orthophoto based on our drone images from 2022!

Importantly, our drone photographs show more features than those documented by Vila. Now that we have relocated this site, it will be possible to verify it in the field once we can go back to Sudan and try to obtain more certain dating evidence. This is particularly relevant to understand the dry stone walls in the area, the presumed irrigation systems (see Dalton et al. 2023) and the changing land- and riverscapes in Attab and Ginis.

Successful survey in Attab West – from my desk in Munich

These days, it is anything but easy to think of our friends and colleagues in Sudan. After all, our working area in northern Sudan has seen the worst rainfall in decades and there is still no end to the war in sight. Nevertheless – inspired by the EAA last week in Rome and fully motivated by meetings there with colleagues who also work in Sudan – I was able to achieve great results regarding our survey in Attab West in the last few days. It was a kind of by-product of my preparation for the International Conference for Meroitic Studies next week in Münster.

Among other things, I will be talking about dry-stone walls in Münster – and that’s why I took another look at all our drone images and, above all, the georeferenced orthophotos and digital elevation models, especially from Attab West and Ginis West.

The level of detail in these photos and models is simply marvellous! And so I was finally able to correctly localise a site in Attab West that I had never actually found on site in Sudan! But that will be a topic for another time.

Today we want to focus on a detail about the New Kingdom settlement site 2-T-62. Vila describes it as a habitation site whose structures are spread over a series of small mounds that extend from east to west over 200 metres and a width of 50 metres, 175 metres from the Nile. The site also contains several dry-stone walls, although their dating is not certain.

For a long time, we weren’t sure whether the site we excavated in 2022 and 2023, AtW 001, really belonged to the larger site 2-T-62 or not – but the answer is now a resounding yes. The special discovery this week, however, is that from my desk here in Munich, I have finally found the mudbrick building 2-T-62/1 that Vila excavated in the 1970s!

It was simply not recognisable on site – there were no more pottery sherds, other artefacts or mudbricks lying around. However, the dimensions can be easily checked on the orthophoto – they fit perfectly. Vila described 2-T-62/1 as a rectangular structure measuring 9 m x 7 m, orientated from east to west, of which only one layer of the foundation walls survives (Vila 1977, 88-89). Inside, a courtyard with a fireplace was identified in the north-west corner, bordered by rooms to the east and south. The room in the south-east corner contained the remains of a schist floor/pavement – something we know very well from the urban sites of Sai Island and Amara West. Some of the schist slabs can still be recognised on the orthophoto.

The digital elevation model also clearly shows the excavated building and the surrounding landscape. AtW 001 is located on a small mound to the west, the building 2-T-62/1 on another mound further to the east. A possible palaeochannel runs north of the two mounds from east to west (see Budka et al. 2023).

This successful remote sensing and the new results of 2-T-62 are comforting in several ways – on the one hand they clarify open questions and on the other hand they offer a very good opportunity to analyse our data even when we cannot be on site in Sudan.

Presentation of DiverseNile at the EAA in Rome

All roads lead to Rome – this was especially true last week for 5000 archaeologists who all came to the 30th annual meeting of the EAA.

Chloe Ward and I were among this impressive number of participants to present the DiverseNile project. Fortunately, both sessions in which we presented also included a number of other presentations on Egypt and Sudan, which shows that our field is also increasingly represented at the EAA.

My talk was on the very first day in a session organised by Maria Gatto and colleagues entitled “The Archaeology of ancient Borderscapes: Multiple approaches, new paradigms.” This session was related to Maria’s The Borderscape Project. The lectures covered a great depth of time and geographical range – and yet we had a very solid thematic basis for discussion, regardless of whether it was about the Nile Valley, the Middle East, the Levant or various parts of Europe.

In my own presentation, I focused on the Dal cataract area as a kind of buffer zone between Lower and Upper Nubia and explored what we can learn about it from the finds in the MUAFS concession. My case studies included results from surveys, rock art and excavations at the sites GiE 003 and AtW 001. I also argued that our contact space biography approach is well suited to understanding the complexity of cultural dynamics often found in borderscapes.

Chloe found the perfect session for her expertise in the construction and production of knowledge in excavation archives. She attended the session “Old excavations and finds, new data and interpretations: The use of archices in current archaeological research projects”, which was organised by Kerstin Hofmann and colleagues on Saturday. This session also included a wide range of very exciting presentations. Chloe emphasised in her talk „Knowledge construction in and with the archaeological archive“ the methodological challenges we need to consider when working in the MUAFS concession and with the data published by André Vila in the 1970s.

As with every conference, however, the EAA in Rome was primarily about the discussions outside of the presentations, meeting old friends again and getting to know new colleagues. And of course, there was also Rome – a beautiful city that had far too much to offer. The social events of the conference were real highlights here – starting with the great location of the welcome party directly at the Palatine in the Vigna Barberini – what a luxury to be able to enjoy this place in the evening as an archaeological community!

One of the stunning sunsets last week in Rome – here with the obelisk on the Esquilin.

Of course, there was also time for some city tours – in my case, of course, tours to the various obelisks. Museums were also freely accessible to all participants – I was particularly impressed by the Villa Giulia and the National Etruscan Museum housed there.

Both the architecture of Villa Giulia, but also the contents of the museum are breathtaking and simply beautiful!

In any case, we are already looking forward to the next EAA, which will take place in Belgrade in 2025.

Co-presenting the MUAFS project at the SASA virtual conference 2024

I am delighted that today there will be a joint presentation by my dear friend and colleague Huda Magzoub and me at the SASA conference. Under the title “The Munich University Attab to Ferka Survey Project 2018-2023: Archaeology, gold, and landscape” we will summarize some aspects of our work in Sudan.

Since Huda is currently having very restricted internet, being displaced with her family in Sudan because of the current war, she sent me a video which I incorporated in the presentation. As much as it hurts not to be able to see her online or in person, it’s a wonderful feeling to present some outcome of our common work and to focus for a change on archaeology & scientific research despite of all the tragedies connected with the war in Sudan.

In our paper today, we will give an overview of the activities and results of the MUAFS project from its start in 2018 until 2023, with a special focus on new findings regarding ancient gold working in the region. In addition, modern gold working and the challenging of preserving cultural heritage in a remote area in times of war will be addressed. Thus, the presentation will follow a comparative approach to analyze gold working throughout the ages. This is especially relevant for Sudan as gold mining has been already in ancient times not just an economic activity but a testament to technological and cultural advancements. Gold has served as a catalyst for cultural evolution, economic prosperity, and sometimes conflict. We will address these aspects and thus highlight some features of the multifaceted story of gold in Sudan, tracing its influence from the dawn of civilization to the contemporary era. Finally, modern concepts of ancient gold working can be critically revisited thanks to the new evidence in the MUAFS concession, making the paper highly relevant for the general theme of the conference.

I am very grateful to the conference organizers for accepting our paper and for giving Huda as a displaced Sudanese archaeologists a forum to share her research in times of war.

Upcoming DiverseNile Seminar: „Tracks on the sand, ancient Egyptian mobility in the desert“

While the summer break is approaching, I am delighted to announce the next DiverseNile Online Seminar next Tuesday. Dr. Mohamed Osman will give a talk with the title „Tracks on the sand, ancient Egyptian mobility in the desert“.

Mohamed is the Director of the Coptite and Theban Desert Eastern Hinterlands survey project, Visiting Scholar at Humboldt University Berlin and Visiting Scholar at New York University. He is an expert about trade routes in ancient Egypt and Sudan. His book published in 2022 (Osman 2022) highlights the possibilities to trace Old and Middle Kingdom (3000 to about 1700 BCE) trade routes using textual evidence, archaeology but also satellite images.

His DiverseNile talk will be about the approaches and methods used when researching about travelling routes. Starting from the theoretical backgrounds and the GIS spatial analysis and how it can be useful, Mohamed will also outline how we can detect the errors in this analysis.

The upcoming DiverseNile Seminar will present case studies from both the Western and Eastern Desert. One particular example will be Mohamed’s discussion about the route between Aswan and Kerma.

I am very much looking forward to this talk presenting fresh research about patterns of ancient mobility in the desert!

A Middle Kerma Period burial in Ginis East

While our PostDoc Hassan Aglan is busy with finalising the documentation from our excavation in 2023 in Kerma cemetery GiE 003, I went back to some tombs we excavated there already in 2022. Today, I would like to present a very interesting burial which is characteristic for the Middle Kerma Period (see Budka 2022).

Feature 26 during excavation in 2022 (photo: M. Bergner, © DiverseNile)

Feature 26 in Trench 2 is a representative circular pit of the Middle Kerma period with typical dimensions (2.4m in diameter). Like the other structures in GiE 003, this grave was also looted. Nevertheless, some interesting finds were found: human and animal bones; pottery; a wooden fragment; a snail which is pierced and functioned as a pendant; a pebble pendant; 86 small sandstone disc beads; 10 small faience disc beads (blue); 1 large flat disc bead made of shell/bone; 1 small green faience disc bead and one copper dagger.

The charming pendant made from a pierced snail (photo: R. Lemos, © DiverseNile)

Feature 26 is the only burial in Trench 2 which yielded some personal adornments (a beautiful snail pendant and a pebble pendant, both of Nubian tradition) as well as grave goods like a dagger and two animal offerings in situ. That various materials were used for beads in diverse sizes in this tomb is also remarkable.

Various beads from Feature 26 in different materials (photo: R. Lemos, © DiverseNile)

The dagger is especially significant – unfortunately, MUAFS 027 is a broken piece (12.2 cm in lenght), decorated with four lines stemming from the tip until the bottom, forming a triangular pattern.

Broken dagger from Feature 26 (photo: R. Lemos, © DiverseNile)

Copper daggers are well attested from funerary contexts in Kerma city and are probably associated with ceremonial use. Following Andrea Manzo (2016), this dagger can be interpreted as an indicator of elite status and Kerma identity (see also Walsh 2022).

However, one of the ceramic vessels from Feature 26, 363-3/2022, a small black topped bowl with irregular incised decoration is slightly unusual but has parallels in both the Kerma tradition and the Pan-Grave horizon (de Souza 2019, 214, fig. 19a).

While most of the ceramics found in Feature 26 are typical for Middle Kerma burials, this vessel maybe also links to the Pan-Grave horizon and illustrates the cultural diversity attested in GiE 003.

This might illustrate cultural encounters between various Nubian groups in the region. Considering the discovery of Feature 50 in Trench 5 in 2023, this is now especially likely.

Similar to Feature 50, two almost complete animal skeletons were found in Feature 26. They were carefully excavated by our inspector Huda Magzoub and appear to be goat/sheep, but this needs to be confirmed by zooarchaeological analysis. At the Kerma cemeteries of Ukma and Akasha, also gazelle offerings were frequently found in Middle Kerma circular pit types (see Vila 1987, 32-33 and e.g. Tomb 2, 39, fig. 41; Maystre 1980, 190).

Overall, Feature 26 offers a wealth of stimulating questions and shows how much potential there is in the cemetery GiE 003 and that our work is far from finished.

Reconstructing the burial of Feature 50 in cemetery GiE 003

I’m thrilled and privileged to have become part of the DiverseNile team in November 2023. My primary role entails consolidating and organizing the data on the variability of funerary monuments excavated in the Attab to Ferka region of Northern Sudan during the 2022 and 2023 seasons. Our PI Julia Budka has given me the specific task of preparing the documentation of Feature 50 from Trench 5 in the Kerma cemetery GiE 003 (see Budka 2022). Interestingly, this burial shows many features associated with the Pan-Grave culture.

Different models of Feature 50.

The filling of Feature 50 comprised a diverse array of artifacts (see Budka, Rose, Ward 2023, 34), including pottery sherds, bones of at least one individual and three goats, beads, remnants of a wooden bed, alongside a mix of dense clay or mud fragments. The latter might have constituted a section of the superstructure wall surrounding the burial (cf. Irish 2007, 59, Figs. 2-3). Due to their dispersed nature within the tomb, not all of these finds were unearthed together or found within a single layer, necessitating their documentation either partially or separately. 

Using Metashape and Adobe Photoshop to rectify photos.

Because different parts of the same level were documented separately, I endeavored to amalgamate all these disparate 3D models into one comprehensive representation using Adobe Illustrator. This involved consolidating all the finds in a unified layout. Additionally, I utilized site photos, rectified them through programs like Metashape or Photoshop, and incorporated them into the combined models.

Using close-up photos for the finer details

I also leveraged daily site information, occasionally using the models as close-ups for finer details. Furthermore, throughout this process, I engaged in numerous discussions with Julia to ensure accuracy and completeness. 
In the end, through our collaborative efforts, we successfully integrated all elements into a single cohesive representation, meticulously illustrated using Adobe Illustrator.

I and Julia Budka discussing the different details of Feature 50.

The clarity of having everything consolidated sparked the idea of creating a reconstruction view using Adobe Illustrator. Inspired by this, I began exploring parallel cemeteries associated with the Pan-Grave horizon, including C-group burials (which are a bit earlier but nevertheless useful parallels). To enhance the visualization, I utilized Photoshop to craft different positions for the goat skeletons. However, despite these efforts, the original view remained somewhat unclear. This led me to consider creating a 3D model reconstruction using Google Sketch-Up, providing a clearer representation of all the features and finds.

Finally, I managed to develop a preliminary 3D reconstruction, but further investigation is needed. Interestingly, Pan-Grave burials, contrasting to Kerma burials, normally do not have wooden funerary beds.

My preliminary 3D reconstruction of Feature 50.

One last aspect: It’s incredible how something as simple as a color choice can drastically alter the way we perceive a scene. Chloe’s observation about the light blue floor of my reconstruction resembling a swimming pool was certainly amusing, but it prompted a smart adjustment to a grayish color to avoid any unintended connotations. These lighthearted moments amidst the serious work of archaeological reconstruction bring a sense of fun and camaraderie to the team.

The ancient city of Kedurma and its hinterland: DiverseNile Seminar by Mohamed Bashir

The start of this year’s DiverseNile Seminar on May 7th is approaching! I am very much looking forward to the lecture by Mohamed Bashir (currently Visiting Research Scholar, Institute for the Study of the Ancient World, NYU) with the title “Lost landscapes, hidden histories: Palaeoecological reconstructions and archaeological investigations of the ancient city of Kedurma and its hinterland, Northern Sudan”.

Mohamed kindly provided us with an abstract for his talk:

„This study addresses the complicated/unexplored relationship between the ancient city of Kedurma in the Third Cataract region of northern Sudan and the surrounding hinterland. It focuses on the reconstruction of the palaeoecological conditions and the exploration of the archaeological remains, looking for the dynamic process that shaped the landscape over time in interaction with environmental factors and human activities. By integrating palaeoecological data and archaeological finds, this study seeks to uncover the historical development of the city and its hinterland.

Through interdisciplinary approaches, including survey, excavation, and analysis of archaeological artefacts, we can identify patterns of land use, settlement dynamics and cultural interactions. Through analysis, we seek to reconstruct past environments and human interventions in this urban periphery. This research contributes to a deeper understanding of the surrounding landscapes of the Third Cataract region and their impact on the development of Kedurma, as well as their significance in a broader historical narrative.

Ultimately, this study sheds light on the interconnectedness of human societies, urbanization and environmental change and offers valuable perspectives for urban planning, heritage conservation and sustainable development.“

This presentation ties in perfectly with the goals of the DiverseNile project and our investigations of the hinterland of the ancient cities of Amara West and Sai Island applying the landscape biography approach. This case study will also showcase the importance to investigate urbanization processes in the Middle Nile – also in respect to sustainable development goals as Mohamed pointed out. All in all, there are plenty of reasons why you should attend this upcoming seminar!

Regionality of stone quarrying in Nubia: the case study of a granite quarry at Ferka West

The most recent publication of the ERC DiverseNile Project focuses on landscape and resource management in Bronze Age Nubia. Here, I would like to present some thoughts on the regionality of stone quarrying in Nubia with a case study from the MUAFS concession.

Stone is a natural resource which has typically been associated with Egypt, being regarded as a raw material of little importance for Nubian cultures. However, the quarrying of stone played a role in the complex framework of cultural exchange of Middle Nile communities with Egypt (see Budka 2024). Whereas Nubian sandstone (quartz sandstone) only started to be used as building material in the Middle Nile during the Middle Kingdom, mostly for Egyptian fortresses, there is evidence for a much earlier use of natural- and dry-stone architecture, in both settlement architecture and funerary buildings (cf. Liszka 2017). Sandstone architectural pieces were also well integrated within Nubian monumental architecture (e.g., the columns and stelae at the eastern Deffufa in Kerma, see Budka 2024 with references). Some of the most important sandstone quarries during the New Kingdom can be found at Sai Island – we have studies these quarries already during the ERC AcrossBorders Project and will come back to the topic within the framework of our present project in the near future thanks to the expertise of our PostDoc Fabian Dellefant.

Granite is another important stone quarried in Nubia. While the most renowned granite quarry used for building projects and objects in ancient Egypt over millennia is located in Aswan, there are also a number of granite quarry sites in the Middle Nile. They are less well known and seem to have been used for a considerably shorter amount of time.

The quarry site of Tombos with an unfinished royal statue.

One quite famous example is the site of Tombos close to the Third Nile Cataract. The site includes a large quarry of magmatic rocks, principally granite and granitic gneisses, with known activity from the 18th Dynasty until Napatan and Meroitic times, particularly for statues and stelae. One particularly striking left-over in the quarry is the beautiful, although unfinished royal statue of presumably Napatan date.

There is no clear evidence that the quarry site of Tombos was used prior to the New Kingdom (Klemm, Klemm and Murr 2019, 28).

Another type of granite, pink granite, is available just south of the Dal Cataract in the MUAFS concession. This brings me to my case study: site 3-L-6 is a large red granite quarry at the foot of Jebel Kitfoggo in Ferka West – well noted by Vila and others during the 1970s survey (Vila 1976, 72−73). We visited the site during our 2022 survey of the MUAFS project – the landscape is fantastic and the pink granite very picturesque.

The site 3-L-6 at Jebel Kitfoggo is one of the highlights in the MUAFS concession area.
A large number of stone working traces can be observed at the pink granite quarry 3-L-6.

Fragments of unfinished columns in the southern part of the site testify to an intensive use in Medieval times for architectural pieces (Welsby 2002, 173).

The quarry was clearly used for architectural pieces like columns.

This is supported by evidence from settlement site 3-G-30, just to the north of 3-L-6, where Medieval ceramics were found on the surface. The building technique and general layout of these stone-built huts are also typical of the Medieval era.

Part of site 3-G-30 in close vicinity of the granite quarry.

Although several Kerma sites are also identifiable in the surroundings of 3-L-6, there is no evidence for Bronze Age or Iron Age use of the granite quarry at Jebel Kitfoggo.

It is interesting to stress that both Tombos and Jebel Kitfoggo were used for a relatively limited time span compared to other quarry sites. These examples illustrate regional patterns in quarrying in the Middle Nile, but they also show the need to consider political and historical circumstances when investigating the management of raw material and resources (Budka 2024).
