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.

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.

Not all archaeology takes place in the field!

Since joining the project in June, I have been busy catching up on the research that has been conducted to date. A considerable amount of this goes back much further than the start of the DiverseNile project to an archaeological survey which took place between 1969 and 1973 directed by André Vila (Budka 2020). As much as we archaeologists enjoy excavation, we also spend a huge amount of time using and building on the work of our predecessors (see also the earlier blog posts by Rennan Lemos and Veronica Hinterhuber). This is particularly important when considering large concession areas such as the one held by the DiverseNile project and the questions the project poses.

Published plan of the area surveyed between 1969 and 1973 (Vila 1979)

Past work such as Vila’s survey can help inform current (and future!) projects in myriad ways. At the most basic level, we can use the results to help locate potential sites of interest for the project and then identify and re-explore them in the field in Sudan. This can also be significant in noting changes in archaeological sites since Vila’s survey, which is crucial for their preservation (Budka 2019; 2020). We can also integrate past data into our current research, increasing the data we have available at our disposal to answer our present research questions. Finally, we can use this survey data to explore research and archaeological practices both today and in the past. Understanding these practices is crucial as they directly influence the way that archaeological knowledge is constructed (Ward 2022). Therefore, a key consideration when using Vila’s data is to understand how it was collected and presented at the time, this means we can make use of it much more effectively. To this end, considering Vila’s results as ‘legacy data’ is a useful way of integrating this past research into our current project.

Normally, the term legacy data in archaeology is used to define ‘obsolete’ archaeological data but, given the vast importance of digital data for any kind of analysis, manipulation, or mapping, this can broadly be applied to any data which is not digital (Allison 2008). As such, any work involving the re-contextualisation, application of modern techniques, or modelling of past data can be considered working with legacy data (Wylie 2016). Thinking of this evidence as legacy data rather than simply data is crucial when using it in any new or future research as it demands a more complex engagement with the material then simply extracting quantitative data. It would be redundant to simply apply new methods to old data, without engaging with more fundamental questions which consider how the data was originally collected and how it fits into the broader historical and methodological contexts of previous studies.

Fortunately for us, Vila’s survey is comprehensively published across 11 volumes, all of which are available on the website of the SFDAS (Section française de la direction des antiquités du Soudan). The volumes are nicely bookended by an introductory volume — which provides crucial information on how the survey and recording was conducted by the team, as well as the classification system used — and a concluding volume — which provides some quantitative analyses of the results of the survey.

Classification of sites used by Vila during the survey (after Vila 1975)

This is a fantastic resource for the project to draw upon as a key consideration when making effective use of legacy data is not only to understand the methodological processes used, but also to ensure the replication of past results (Corti and Thompson 2004; Corti 2007; Corti 2011). As in any science, the reproducibility of results is fundamental in ensuring the accuracy — and therefore usability — of past research, which is crucial when incorporating it into contemporary research. Furthermore, advances in the archaeology of Sudan means that some of Vila’s results — for example, in terms of phasing — may well need to be re-examined and ‘updated’ to take into account the half-century of subsequent research.

Of course, all of this leads to additional questions on the future of the research and data created by the DiverseNile project. This includes thinking about the best ways to collect, store, and share our data and ‘futureproof’ our work.  

Keep reading the blog for future updates on Vila’s work and its integration into the DiverseNile project!

Getting ready to fly to Sudan

The Christmas weekend is just about to end, and I am currently packing my last suitcase – despite of omicron & the pandemic, but of course with much caution and aware of the most recent political developments in Sudan, we are getting ready to fly to Khartoum tomorrow.

It will be a very brief season with a tiny team – just Rennan, Cajetan and I will travel. One focus of our planned work is on the study & documentation of object’s stored in the Sudan National Museum, coming from Vila’s survey in the 1970s in the present MUAFS concession. Rennan will focus in particular on ceramics and small finds from some of the New Kingdom tombs. Especially Ramesside material is highly interesting and raises many questions concerning the continuity of sites in the pre-Napatan era.

Up in the north, at our excavation house in Ginis East, I will focus on some logistics, preparing the upcoming excavation season planned for spring 2022. I also plan some survey work with our inspector and Cajetan will concentrate on setting survey points and taking measurements.

Of course, we will keep you updated – maybe not during the season, depending on the quality of the internet and connection.

Hoping that most of our plans will work out, but also very much prepared for surprises and the need to improvise, I am just really very happy to be soon back in Sudan, after almost 2 years!

New approaches in the past – new approaches in the present

As my colleague and ‘scientific counterpart’ Rennan Lemos, responsible together with our PI for Work Package 2 (The Variability of Funerary Monuments), pointed out so perfectly in his blog entry On the footsteps of Vila and the archaeology of monumental surveys in northern Sudan, a number of different factors determine how we have to approach our engagement with the past today. Not only do we archaeologists have to keep in mind our own social or cultural conditioning, our own socialisation, which is always an on-going process, but we also have to take into account the zeitgeist of our predecessors, and thus the working methods influenced by it, when we include their previous results.

In this regard, the method that Vila and his team applied for their Archaeological Survey in the 1970ies, which also covered the MUAFS concession area from Attab to Ferka, is equally relevant for settlement sites and thus for Work Package 1 (The Variability of Domestic Architecture).

Although Vila and his team also followed up on earlier surveys in Sudan, they deliberately chose an approach that was kind of new for their time. Their main aim was to give an idea and thus evidence of the cultural legacy, to raise awareness of the archaeological value of the explored regions. Linked to that was the explicit wish to pave the way for further fieldwork in the future.

Concerning the settlements, in slight contrast to the cemeteries, where clearing or minor excavations were carried out more frequently, the major rule was that survey work must avoid disturbing the original condition of the archaeological sites. Instead of using invasive methods that would have resulted in significant destruction, (in most cases) work was limited to indicating the existence of the sites, documenting their visible remains and giving a current status report on them. The documentation system chosen by Vila and his team was based on a strict, predetermined catalogue of guidelines (Vila 1975, Volume I). Exemplarily mentioned shall be the given information about the localisation, the extent of the sites or the geographical features, and – in this point naturally somewhat more subjective – the classification of the respective archaeological value. The latter dictated quite decisively, f. ex. the extent of sampling, which was also subjected to strict rules. Another positive aspect to be highlighted is a topic usually rather neglected: The consistent application of the terms chosen for their survey (f. ex. vestiges for removable witnesses, like sherds or stone implements; remains for any kind of fixed structure) as well as the explanation of chosen terms like settlement, camp site, occupation site etc., and not least the description of the problems they were confronted with when creating their system.

Although Vila and his team likeable (and very well understandable for any field archaeologist) admitted their own hardships in this approach, having to leave to other people what they discovered, it is especially this transparency that makes it particularly helpful for us subsequent scholars to comprehend the information they gained, documented and what they understood by it.

This systematics, which at that time was still applied in the field via punched cards created according to the guidelines and not unlike an analogue database (Fig. 1), enables the old survey results to be easily transferred to a now digital Database (FileMaker Pro), the ERC DiverseNile Database for ‘Kerma’ and ‘New Kingdom’ sites, I designed for Work Package 1 (see also the Petrographic Database my colleague Giulia D’Ercole designed for Work Package 3).

Figure 1. Selective card used for documentation in the 1970ies (Vila 1975: 19, Fig. 2).

This new database contains on one hand all the available documentation published by Vila concerning the settlement sites, whereas the then state of research is contrasted in a clear and critical separation with the new data gained from our own studies, which includes f. ex. not only new sites, new maps, new photographs but also a revised dating for several dates given by Vila. As strongly intertwined topics it also includes basic information on cemeteries.

This easy to handle database, which I will give you here a short overview of, can be flexibly modified and adapted to the on-going work process (Fig. 2): Structured in three parts, the database first provides a short general information about the site, f. ex. its Name and location, the AMS-No (alphanumeric classification regarding the 1, 250 000 map sheets of the Sudan Survey Department, a method firstly implemented by W.Y. Adams 1961, further elaborated by F.W. Hinkel and used by Vila), or new Way Points (taken by the MUAFS team). Important entries are of course the site’s Dating given by Vila, which has been updated if necessary (Site Date new). The second, more detailed part includes the elaborated Site description by Vila together with already published photos, drawings or sketches, again updated and compared with new results collected in our last seasons (f. ex. Observation/New Excavations). The third section serves to cover specific data relevant for the settlements within Work Package 1, such as f. ex. Superstructure or Building Techniques, as well as entries like Shape or Material.

Figure 2. Layout of the ERC DiverseNile Database for ‘Kerma’ and ‘New Kingdom’ sites (detail).

An equally beneficial option within FileMaker is the integration of other databases I made, the ERC DiverseNile Object Database (Fig. 3) and the MUAFS All Finds Database, which contain the data of all the new finds we so far recorded and are accessible through an easy command.

Figure 3. Layout of the ERC DiverseNile Object Database.

Altogether these databases are an extremely helpful and time-saving working tool to sort and select relevant data at a glance (or a click), revealing not only the wide variability of sites in our concession area but also the cultural diversity of the archaeological remains in the Attab to Ferka region, including at the moment 53 recorded sites relevant for Work Package 1.

Being able to expand and optimise these databases during the work process, they also reflect at one glance the development of past and present research: This holds f. ex. true for the attribution of sites indicated by Vila as either ‘Kerma’ or ‘Egyptian New Kingdom’, defining them then still as more rigid cultural units, than we do today. Numerous data from revisited sites and newly added ones show a much closer interconnection of cultures in this region – thus supporting our new approach to move away from these strict categories and going a step further, with our PI introducing the preliminary term Bronze Age Nubia as a starting point (Fig. 4). Provided with newer methods in archaeology and fresh promising data we are looking forward to further shedding light on this flourishing and dynamic region in the periphery of Sai and Amara West.

On the footsteps of Vila and the archaeology of monumental surveys in northern Sudan

Every archaeologist knows that what we write about the past is mediated by present-day questions, expectations and challenges, but also state-of-the-art documentation techniques. Archaeologists don’t simply reconstruct what happened back in the day. Instead, archaeological and historical narratives are essentially modern constructions that can either be repaired or demolished as scholarship moves forward. Archaeological research is also mediated by complex site and object biographies that span thousands of years; e.g., in our case, from the Neolithic to monumental surveys carried out in northern Sudan in the mid-20th century.

To understand tombs, burials and mortuary objects in the region from Attab to Ferka we need to understand the impact of André Vila’s work in the region, the epistemological framework from which he was reporting and his methodology. How Vila’s work materialise in the landscape directly affect the questions we ask and the methodologies we apply today. Not surprisingly, archaeologists in Sudan usually deal with traces left by earlier archaeologists at various sites, and retracing their steps becomes a fundamental aspect of accessing the past through remaining material culture (e.g., Howley 2018: 86-87).

Vila’s survey can be seen as part of a long tradition of large-scale surveys going back to the first Archaeological Survey of Nubia (see Adams 2007). From Dal (the southern limit of Lake Nubia) to Nilwatti Island, Vila identified 462 sites of which 219 sites are within the MUAFS concession (figure 1). These sites were attributed to cultural units, e.g., Kerma, Christian etc. Even though Vila noted that various sites belonged to one or more cultural units, today archaeologists approach those ‘units’ more fluidly, especially in situations of cultural exchanges, which is especially true for Kerma and New Kingdom sites. On the one hand, revisiting sites surveyed and reported in the 1960s and ’70s requires us to contextualise archaeology to ‘deconstruct’ theoretical biases and ask different questions. On the other hand, Vila’s methodology determines the extent to which sites can be explored.

Figure 1: distribution of sites in the MUAFS/DiverseNile concession area (map: C. Geiger)

In terms of method, Vila’s survey aimed to keep disturbance to sites to a minimum. Test excavations and sampling followed rigid guidelines and excavations were only carried out when cultural affiliations couldn’t be distinguished otherwise, e.g., based on surface finds. Cemeteries were approached in a slightly different way. Cemeteries were usually cleared to determine their extent and number of graves at each site. A few graves were fully excavated and recorded, as well as ‘peculiar’ collective burials (figure 2).

Figure 2: Bagagin Farki, Ginis East. “Egyptian” New Kingdom pit burial containing an individual deposited in extended position together with sherds from two pots and the remains of other six individuals (Vila 1977, Vol. 5: 47)

In Work Package 2, I am responsible, among other things, for reassessing the material from such graves. For example, comparison of items from graves in our concession area with objects from other sites allows us to shed new light onto different roles performed by the same types of objects in different contexts (Lemos 2020). Scientific analysis of pottery also allows us to explore the (potentially) alternative role of objects in rituals (stay tune to Giulia D’Ercole’s blog!). I am currently collaborating with Kate Fulcher from the British Museum on the topic of mortuary rituals in New Kingdom Nubia based on scientific analysis of artefacts (see Fulcher and Budka 2020 for examples of such approaches).

Working with previously excavated material culture poses several theoretical and methodological challenges, mostly related to the lack of information provided by earlier excavation reports and the problematical categories used to classify things. However, revisiting the burials excavated by Vila holds an immense potential for us to ask different questions within larger-scale perspectives on burial communities, the role of (foreign) objects in the constitution of (local) social relations and identity formation strategies. Comparative approaches to sites and material culture allow us to understand different social realities within Nubia, challenging previous homogenising perspectives on cultural interactions focusing on elite centres. Revisiting sites also holds great potential to unveil things under new theoretical perspectives and using state-of-the-art documentation techniques. This is especially the case because disturbance to sites was limited during Vila’s survey, although looting poses an additional challenge to new fieldwork in our concession area.

Ultimately, researching burials and other sites in our concession area and excavating sites firstly worked by Vila presupposes a deep knowledge of the data sets produced by him, what was ignored/discarded, what was considered worth investigating etc. Previous ways of excavating, identifying and reporting sites also determine the extent to which we can revisit them through excavation and comparative analysis.
