Uncovering the origins of the sandstone used in the construction of ancient monuments offers a unique glimpse into the interplay between natural resources as well as human craftsmanship and interaction. On Sai Island, nestled in the Nile between the 2nd and 3rd cataracts in Northern Sudan, lies Temple A, an 18th Dynasty Egyptian structure. The sandstone used in its construction, sourced from the island’s abundant deposits, has long piqued the curiosity of archaeologists and geologists alike. A recent study delves into the mineralogical and geological characteristics of these sandstones, seeking to uncover their precise origins and the choices made by ancient builders.
The investigation centered on sandstone samples taken from Temple A, and three nearby quarries. Using advanced analytical tools such as polarization microscopy, scanning electron microscopy, and micro-Raman spectroscopy, we were able to analyze the stones in detail. The sandstone clasts were found to be composed predominantly of quartz, making up 90–95%, with minor contributions from feldspar and lithoclasts. Clay minerals like kaolinite and illite were present in varying amounts, forming part of the stone’s matrix. The stones also contained traces of iron-titanium oxides, which had undergone alterations over time due to natural chemical processes.
The study revealed that the sandstone used in Temple A was more finely sorted and contained smaller grain sizes compared to the samples from the quarries (Figure 1a-d). This finding suggests that the builders deliberately selected stones with uniform characteristics to ensure consistency in the temple’s appearance. The lighter color and moderate sorting of the temple sandstone contrast with the darker, poorly sorted stones found at the quarry and outcrops. This selective quarrying points to a sophisticated understanding of the properties of building materials and a meticulous approach to construction.
However, determining the exact source of the sandstone used in Temple A proved challenging. Despite the similarities in composition between the temple stones and the natural occurrences, the analysis could not definitively link the building materials to a specific quarry. We suggest that the stones likely originated from the same geological formation but does not rule out the possibility of multiple extraction sites within the island.
The presence of minerals such as kaolinite and illite in the sandstone’s matrix provided further insights into the geological history of these rocks. These minerals form under specific environmental conditions and suggest that the sandstone underwent stages of weathering and burial over geological time. Iron-titanium oxides, including ilmenite and its altered forms, indicated processes of chemical transformation as the stones interacted with water and other environmental factors. These transformations reflect the dynamic geological history of Sai Island, where tectonic forces and sedimentary processes shaped the materials long before they were quarried for use in ancient architecture.
While the exact quarrying practices remain unclear, the findings underline the care and intentionality that went into selecting construction materials. The builders of Temple A seemed to prioritize not only structural integrity but also the aesthetic qualities of the stone.
The study of the sandstone from Sai Island is a window into the decisions and practices of colonial Egypt in Nubia during the New Kingdom. Through understanding the material choices of the past, we gain a greater appreciation for the deep relationship between humanity and the natural world. Further investigations, including detailed geological mapping and isotopic analyses, could reveal even more about the origins of these stones and the history they carry.
Sai Island’s sandstone is more than a building material—it is a testament to the resourcefulness and artistry of its ancient inhabitants. Each grain of sand holds a story, shaped by eons of natural forces and, ultimately, by human hands. By unraveling these stories, we not only connect with the past but also deepen our understanding of the intricate connections between geology, culture, and time.
I am very pleased to announce the next DiverseNile Seminar. On 26th November, our PostDoc Fabian Dellefant will talk about the sandstones of Sai. Some of you may know that we have already analysed them as part of the AcrossBorders project.
However, what was published in 2020 was a preliminary investigation of sandstone petrography using only polarization microscopy. This study offers a basic understanding, but the attribution of samples to distinct quarrying locations on Sai remained uncertain due to limited data descriptions and micrographs. Providing more detailed descriptions, data, and micrographs would greatly enhance the clarity and coherence of the sedimentary rock groupings, offering valuable insights into the provenance of the Nubian sandstones and the sourcing practices of the builders of Temple A.
Therefore, I am delighted that Fabian will present the results of his re-investigation whether the origin of the Nubian sandstones from Temple A can be specifically traced back to local quarries associated with the New Kingdom town.
Don’t miss this exciting seminar on the exploitation of sandstones and quarry work in New Kingdom Nubia!
Back in 2022, I attended a very nice workshop in Mainz: “Excavating the Extra-Ordinary 2. Challenges and merits of workings with small finds“. The proceedings of this event are now published and available in open access.
I am delighted that the book includes my contribution focusing on re-used sherds, presenting the case study from Sai Island.
I also address the question of lids – are these small finds? or pottery vessels? and how shall we deal with them? This also applies to some interesting findings in the MUAFS concession I have discussed earlier on this blog.
The main objective of my chapter in the Mainz volume, apart from advertising reused pottery sherds as extremely exciting (but also challenging) category of finds, was to highlight the concept of object biography and taskscapes which we apply to the Attab to Ferka region (Budka 2024).
I argue that reused ceramic sherds were chosen based on the colour, porosity, stability and hardness of the individual pieces which depend on the specific fabric (see Raedler 2007). Similar to the chaîne opératoire reconstructed by Kate Fulcher for painting materials from Amara West (Fulcher 2022) or by Giulia D’Ercole for pottery from the Middle Nile (D’Ercole 2024), the task of producing sherd tools can involve a number of different places, people and actions. The production process as well as the activities carried out with the newly created tool are well suited to consider tool kits and dynamics taskscapes in ancient landscapes and micro-contexts (for the concept of taskscape see Ingold 1993).
The technical choices are based on the cost (time and resources), availability and workability of the raw materials, in this case the fabric of the chosen sherd. The latter also determines the tools necessary for reworking a sherd (e.g., smoothing the edges or piercing the pottery). There are also important questions regarding what time of year the sherd tools would have been produced. Although most of the tools were most likely produced ad hoc, pottery making was probably mostly a seasonal activity. As such the making of sherd tools may also have been primarily carried out on a seasonal basis, in particular for tools used in pottery workshops.
Particularly interesting are tools from the New Kingdom town of Sai which were made from Nubian style vessels. For example, SAV1W 1671 is a circular sherd with a central perforation from a basketry impressed Nubian cooking pot, presumably used as a weight. Although, given the lightness of the material, this piece could have been a token rather than a weight. In many cases, we can also assume that reused sherds have multifunctional uses.
Another soft Nubian example for a sherd tool is the rim sherd of a Black-topped Kerma vessel, SAV1W 1533. This object fits nicely in the hand, and it is possible to get a good grip, thanks to the rim and the rather soft material. The burnished surface suggests it was more likely used as a spoon rather than as a scraper.
These are just a few examples to show how relevant reused sherds are for questions relating to everyday life and activities. Altogether, in order for reused sherds to contribute to a better understating of taskscapes in ancient Egypt and Nubia, these intriguing objects need to be studied in a more integrated way.

In my own presentation, „The International Age in pharaonic Egypt: aspects of trade, exchange and marking systems“, I focused on the distribution of marked Oases amphorae as well as on the question of pot mark traditions in Nubia.
For me, it is striking that there are no pre-firing marking practices on Nubian ceramics – but a new trend for post-fired marks attested in the Middle Bronze Age on Egyptian imported Marl clay vessels (in C-Group and Kerma contexts). This is for example well illustrated by the upper part of a storage vessel we found last year in the Kerma cemetery GiE 003 at Ginis East: a large post-fired mark was scratched into the Marl clay surface – presumably in Nubia and for sure intended to transmit a code (as well as decorative aspects?).
There is still much research to be conducted on these post-firing pot marks on Egyptian jars found in Nubian contexts – aspects of agency (by whom, where and how was the scratching done) as well as sensory facets (the Egyptian jars have a totally different hardness, colour, and texture than Nubian Nile clay vessels) need to be considered.
Another important aspect of my presentation was the comparison between the pot mark tradition on New Kingdom Sai, Elephantine and in the rural hinterland of Sai, in the MUAFS concession. Here, I got much inspiration from a splendid chapter in an edited volume by Juan Carlos Moreno García with the title “Markets, transactions, and ancient Egypt: new venues for research in a comparative perspective” (Moreno García 2021).
I completely agree with Moreno García (2021) that New Kingdom temple towns in Nubia like Sai were “multifunction centres used, among other purposes, to facilitate contacts between different peoples arrived there to trade, and that some kind of divine sanction at a sacred environment was considered indispensable to formalize the transactions that occurred there.” The last aspect is especially interesting, placing the temples within the towns into a new context – the conversion of the religious landscape of New Kingdom Nubia has already received much attention, but not yet within the framework of trade and transactions. The general role of the temple towns as multifunctional and as trade hubs is well established and was already discussed by several scholars (see Budka 2020, 401, 407 with references as well as passim).
Within New Kingdom Nubia, it is especially relevant to look beyond the colonial towns with their temples, harbours and large-scale storage facilities. This is where the DiverseNile Project steps in and adds much food for thought based on the evidence in the MUAFS concession which is the hinterland of Sai in the 18th Dynasty and of Amara West in the Ramesside era.
Inspired by reading Moreno García’s 2021 chapter, I think it is possible to view the intriguing site AtW 001 from a new perspective. Since 2022, I was convinced that this rural site has something to do with the exchange of goods, especially the distribution of ceramics in 18th Dynasty Nubia (see Budka 2022, as “control posts for trade, gold transport and possibly the communication between hinterland communities and the newly established Egyptian centre on Sai Island”).
Based on the results from the 2023, we could go a bit further and suggest that the “site might well have been linked to seasonal traffic/routes into the desert, possibly in connection with the provision of transport animals and livestock for gold working expeditions” (Budka et al. 2023, 29). In this context, we observed that “The lack of significant architectural remains suggests that AtW 001 was linked to a nearby settlement or temporary, possibly seasonal structures” (Budka et al. 2023, 30). Following ideas by Moreno García, I would now like to add that the lack of substantial architectural remains at AtW 001 could also be explained in a way that the open spaces of the sites were intended to serve travellers and to supervise trade. This would also allow to justify the large number of simple storage pits on the site. With its mix of material culture, including large amounts of Nubian ceramics as well as in-between vessels (see https://www.sudansurvey.gwi.uni-muenchen.de/wp-content/uploads/2023/03/IMG_9979-2048×1536.jpg), the site at Attab West could indeed have functioned as a seasonal market and a meeting place for various groups, including mobile communities.
All in all, New Kingdom Nubia seems to be an excellent case study for state-built meeting points and trade centres like Sai and other temple towns, but also for seasonal and occasional markets as illustrated by AtW 001 – the latter stressing the importance of semi-nomadic and nomadic groups when we talk about the exchange of commodities. These various types of markets and most importantly the diverse communities being involved are likely to be the keys for understanding the multiple use of marking systems we find in New Kingdom Egypt and Nubia.

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).
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.
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!

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.
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.
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.

The next lecture in our DiverseNile Seminar Series 2023 is coming up: on Tuesday, July 4, Kate Spence (University of Cambridge) will be talking about her research in the temple town of Sesebi – “Living at Sesebi: investigating the houses of the New Kingdom town”.
Kate is an internationally well-recognised expert on New Kingdom urban sites and especially house architecture in Amarna and Sesebi. She has published seminal works on the topic and, in my opinion, one of her publications on the 3D form of Amarna houses (Spence 2004) is especially remarkable and extremely useful to be discussed with students in classes on Egyptian domestic architecture.
I am especially delighted that Kate will be giving this talk about lived experiences in New Kingdom houses at Sesebi for several reasons. First, because the site of Sesebi is a fantastic parallel for Sai Island and second, it has always struck me as an especially intriguing site with huge potential (especially for understanding settlement patterns in New Kingdom Nubia). Thus, thirdly, it is not only a great topic for the DiverseNile Seminar Series, but also of much relevance for domestic architecture in the Attab to Ferka region and our own research.
Kate’s recent fieldwork project at Sesebi (co-directed with Pamela Rose) reflects the new boom in urban archaeology in Upper Nubia since the 2000s, with an increase in archaeological fieldwork at sites like Amara West,Tombos, Sai, Dukki Gel and of course Sesebi.
The new work at Sesebi started in 2008 and concentrates on a re-assessment of the work by the Egypt Exploration Society in the 1930s. The most important result of this new mission is that structures and material remains, especially pottery, have been found which pre-date the reign of Akhenaten – the king who is normally associated with the site. It is very likely that Sesebi was already founded at the very beginning of the 18th Dynasty (Spence and Rose 2009, 39, 42; Rose 2017; Spence 2017) – maybe as early as Sai Island.
Join us next Tuesday at the DiverseNile Seminar and learn more about living at New Kingdom Sesebi through Kate Spence’s promising lecture!

As announced last week, the first preliminary report about Kerma cemetery GiE 003 in Attab/Ginis East has just been published (Budka 2022).
Today, I would like to discuss one of the highlights from this cemetery which was published in the EVO paper: a glazed steatite royal scarab with the name of a Hyksos king.
Found in Feature 4, the name of Pharaoh Y’amu is given on the bottom of this piece, MUAFS 005. Already on the day of its discovery, Manfred Bietak kindly helped remotely with the initial reading of the royal name of this scarab – many thanks for this! I am also particularly grateful to Karin Kopetzky, who provided detailed information about the dating criteria of this piece. The design of its back, head, legs, and sides all directly correspond to other known attestations of Y’amu (Tufnell 1984, 32, 35, 37, pl. 61: 3416, 3417, 3418, 3419; Ward 1984, 164) whose exact position within the sequence of 15th Dynasty rulers is unfortunately not clear (see Ben-Tor 2007, 107-108).
Scarabs are in general rare in cemetery GiE 003 and only two pieces have been found in our excavations. The context of scarab MUAFS 005, Feature 4, appears to belong to the later part of the Classic Kerma period, possibly contemporaneous with the Theban 17th Dynasty. As is known from other marginal regions of the Kerma empire like the Fourth Cataract area, our Hyksos scarab might have been circulating in Nubia for some time before ending up in GiE 003’s Feature 4.
The Hyksos king Y’amu has not been attested to in Nubia before the discovery of his scarab MUAFS 005 in GiE 003. Interestingly, in Ward’s sequence he would postdate the other Hyksos rulers attested to at Sai and Kerma as well as at the northern sites. Ward (1984, 164) placed Y’amu in the second half of the 15th Dynasty, but this sequence has been discussed and is not archaeologically confirmed (Ben-Tor 2007, 108 with references).
The textual evidence for contact between Kerma rulers and Hyksos kings has already been addressed from a variety of perspectives. In this context, the appearance of Tell el-Yahudiyeh ware in Nubia and of Kerma wares in Egypt, especially at the Hyksos capital Avaris, were also noted as possible indicators of exchange. Alexander Ahrens and Karin Kopetzky recently examined the appearance of Hyksos scarabs in the context of Kerma burials (Ahrens, Kopetzky 2021). Royal Hyksos scarabs are known from Ukma, Akasha, Sai, and Kerma, as well as several Lower Nubian sites (Aniba, Dakka, Sayala, Masmas, Faras, Mirgissa, Uronarti and Debeira). All of the kings mentioned on these sealings ruled during the early Hyksos period, and it is logical to assume that this was when the Hyksos engaged in direct trade with the Kerma kingdom (Ahrens, Kopetzky 2021, 295 with references and discussion). During the early Second Intermediate Period, the fortresses in Lower Nubia were under Kerma control, and the Hyksos were probably keen to establish trade and direct contact to achieve “continued access to resources and particularly to the Nubian gold essential for trade in the Eastern Mediterranean” (Ahrens, Kopetzky 2021, 295). The Lower Nubian fortresses have always been linked to gold mines and access to gold – recent work has stressed also the importance of Kerma gold working sites in Batn el-Haggar (Edwards 2020, 406-407; 415), and the same is likely for the Attab to Ferka region, especially for Ginis and Kosha. Could the Hyksos scarabs found at Ukma, Akasha, and Sai reflect not only international trade but also, indirectly, gold exploitation between the Second and Third Cataracts during Kerman rule? And could the same apply for the newly found scarab in Ginis?
It is tempting to assume that this new Hyksos scarab can be seen in connection to an intense period of Kerman exchange with the Hyksos kingdom, which sought gold from not only former Egyptian fortresses in Lower Nubia but also sites further south under Kerma rule. Sai’s importance during the Kerma Period might be linked to both the island’s strategic position and its location in a gold-rich region, making it ideal for supervising gold exploitation as we know it from the New Kingdom. Maybe the halting of trade with the Hyksos in the second part of the 15th Dynasty was one of the reasons why the character of Sai as a Kerman stronghold changed during Classic Kerma times (for this change see Gratien 2014; Manzo 2016). It remains to establish possible changes towards the end of the Classic Kerma period in marginal regions like Ginis – and cemetery GiE 003 with its use from Middle Kerma to Classic Kerma times and its close proximity to gold exploitation sites (as well as its connection to desert nomads presumably involved in the gold trade) has here lots of potential for future analysis.

Still on the traces of Nubian goldsmiths, I would like to share some thoughts about a fascinating type and a goldsmith technique common in modern jewellery but already used and widespread in Kerma time: the gold bezel.
Significant for the study of local gold working in Nubia is a scarab necklace with gold bezel from tomb K1053 at Kerma (Fig. 1), dating to the Classic Kerma Period (c. 1700-1550 BCE). This string is composed of carnelian and amethyst beads of different shapes and typologies and a beautiful blue-glazed steatite scarab pendant set in an accurate gold bezel. According to Markowitz, the gold bezel was added and created by Nubian goldsmiths to emphasize the high rank and role of its owner (Markowitz, Doxey, 2014). The elite individual (Body D) of the Classic Kerman subsidiary grave K1053 was a Kerman woman buried with typical personal adornments, such as a silver headdress, a leather skirt with silver beaded drawstring, a necklace of blue-glazed crystal ball beads, a double set of gold armlets and bracelets on her upper and lower arms and this fascinating gold bezel scarab necklace held in her hand (Minor, 2018) (Fig. 2).
Other interesting gold bezel scarabs are attested from Kerma: a blue-glazed steatite scarab back covered with gold plate (K X B, western part, Body XK); a scarab with gold back-cover and two carnelian sphinxes amulets (K 439, Body B); an uninscribed amethyst scarab uninscribed with a gold mounting (K IV B, Body J) (Reisner, 1923, pp. 198-228-305).
Really fascinating traces of a specific typology of gold bezel come from the heart scarab (SAC5 349) of the goldsmith Khnummose, found with his body in the Tomb 26 (Chamber 6) at Sai Island (New Kingdom, mid-18th Dynasty) (Budka, 2021). This inscribed serpentinite heart scarab, discovered by our PI Julia Budka and her AcrossBorders’ Team (read here more on this extraordinary discovery!), was found in situ with gold foil remains. During the process of cleaning, fragile strips of gold were found close to the head of the scarab and only one piece was clearly attached around the base, suggesting the presence of a bezel, most likely made with a very fine gold leaf. Indeed, the largest gold fragment has a large hole pierced through it, probably connected to the holes of the scarab (Budka, 2021) (Fig. 3).
The heart scarabs were occasionally enclosed in gold mountings in Egyptian jewellery during the New Kingdom, manufactured through the use of two main techniques: the lost wax or the welding of two separate pieces of a gold sheet (Andrews, 1994; Schäfer, Möller, Schubart, 1910). Both are still used in modern jewellery; the second technique allows the creation of a particular type of bezel exclusively used for heart scarabs. It’s a gold bezel that not only holds the base of the scarab but is characterized by a T-cage that supports the funerary amulet along the part of the scarab body called elytra (the closed wings), following their shape (Fig. 4). These gold bezel heart scarabs were hung from a gold chain or tourques through a suspension loop welded on the upper part of the bezel or the perforated scarab and bezel. Excellent examples are dated to the 18th Dynasty: the serpentinite and gold heart scarab of Neferkhawet (MMA 729), early 18th Dynasty, Thebes, Asasif (Fig. 5); the green schist and gold heart scarab of Maruta (Tomb of the Three Foreign Wives of Thutmose III), 18th Dynasty, Thebes, Wadi Gabbanat el-Qurud (Fig. 6); the green jasper and gold heart scarab of Djehuty, 18th Dynasty, Saqqara (Andrews, 1994; Budka, 2021).
Coming back to Tomb 26, the family tomb of goldsmith Khnummose, there was also an exceptional steatite scarab ring in gold and silver (SAC5 388) of the 18th Dynasty (Budka, 2021) (Fig. 7). It was discovered with the female Individual 324. Among her bodily adornment, there was also an interesting necklace with carnelian and bone crocodile pendants and beads in different materials, such as gold (exactly 180 beads!). The finger ring has a heavy gold setting, most likely made by wax carving and lost wax techniques. The shank of the ring is in silver, while its small domed caps are gilded. The thin gold wire threads through the scarab, the gold bezel and the gilded caps twisting on both sides of the ring and finally fixed in small holes drilled in the silver shank (for an accurate description of these and other beautiful finds from the Tomb 26 do not forget you can find the complete book here https://www.sidestone.com/books/tomb-26-on-sai-island).
The gold bezel seems to be a distinctive feature of the Nubian jewellery, but additionally, these bezels from Sai come from the tomb of a local goldsmith and his family. Khnummose held two titles: “goldworker/goldsmith” and “overseer of goldworkers” (Auenmüller, 2020; Budka, 2021).
Even if with a less sophisticated mounting than the typology of the gold and silver ring from the Tomb 26, another intriguing comparison comes from Aniba and two scarab rings (n.34, n.36; see Budka, 2021, 212). The moving bezel is fixed to the ring by a thin metal wire that passes through the scarab, twisting on both sides of the ring. The ring n.34 is in silver, while the n.36 is in bronze (Steindorff, 1937, 111, pl. 57, nos. 34 and 36).
During the New Kingdom, the scarab mounted in gold remained the most common design for finger rings (Wilkinson, 1971). This technique, the mounting of the gold bezel, characterized by different methods (Maryon, 1971), appears already among the “innovations” of the Middle Kingdom goldsmithing. The first scarab rings were made from a single wire. From the 13th Dynasty the ends of the ring were equipped with grommets through which passed the wire that held the perforated stone. However, friction between the stone and the metal frequently led to shredding, therefore goldsmiths started to create “a metal protection” for the stone: the bezel (Schäfer, Möller, Schubart, 1910).
It has been suggested that the Egyptians adopted this goldsmithing typology and technique from a foreign people, perhaps from the Mycenaean culture where these rings were used (Schäfer, Möller, Schubart, 1910). However, the gold bezels found at Kerma, used as pendants/amulets rather than rings, but also the later examples from Sai, could attest to a local Nubian typology and manufacturing, the possible influence or technology transfer between Egypt and Nubia and the use of different techniques and specific tools already during Kerma times and through the New Kingdom.

Digital technologies continue to inundate archaeology as a means of bridging scientific and humanistic approaches. More than merely an exercise in playing with flashy machines and fancy toys, 3D printing has wide-ranging implications for fostering education and outreach, the accessibility of archaeological heritage, and explorations in experimental archaeology.
In my first month as a postdoc with the DiverseNile project, I began looking into different strategies and methodologies for making 3D models and prints of small objects. First up, we looked into printing a seal impression from the AcrossBorders project’s excavations at Sai Island. This mid-18th dynasty mud seal impression bears the name of Nehi and the title “Overseer of the Gateway” and is intact apart from a finger smudge in the lower left corner.
We also decided to experiment with printing an inscribed stone heart scarab also from the AcrossBorders project at Sai Island (figure 1). This object was excavated from the 18th dynasty burial of Khnum-mes and is inscribed on the bottom with Chapter 30 from the Book of the Dead (Budka 2021). Check out a blog post from 2017 about this find here.
To create models, we use photogrammetric methods to align photos of the object in Agisoft’s Metashape to create a textured mesh (figure 2). The photos of this object were taken during a study season in Khartoum in 2017 by Cajetan Geiger.
For this project, we needed a printed object quickly for a television appearance (keep reading to find out more!) so I looked into commercial printing options. I came across Xometry, a Germany-based company offering on-demand manufacturing of industrial parts. I like to think that they were both confused and delighted when they saw the small, inscribed objects on their platform!
Pros of this service: Xometry has a well-designed, functional, and easy to use website. With their instant quoting engine, you can upload 3D models (.stl, .obj, and many other formats) and immediately receive a cost and shopping estimate. Also, if there are issues with your model the engine will detect them. You can also choose the specific color, material, weight, and finish of your print.
Cons: While the website has extensive options for types of printing materials, most of the options are obviously very light-weight industrial plastics, polycarbonates, silica glasses, and nylons. If you are aiming for realism in your 3D print, you will not come across colors or materials on this site that can replicate those of many archaeological objects. Also, it should be noted that for this company, the minimum order is €50. If you just want one or two prototypes of small objects, you will have to order A LOT of copies just to come close to this high of a minimum!
Given the drawbacks of working with large 3D printing companies like Xometry, I began to look into the possibility of collaborating with institutes on campus that may offer printers. After a bit of digging, I contacted the Medieninformatik Lab at LMU. Luckily, they have, not one, not two, but three (!) high quality, professional 3D printers; a Prusa Mini+ (PLA-3D printer), a Prusa i3 MK3S+ (PLA-3D printer), and the pièce de resistance, a Formlabs Form 3 (SLA-3D printer). The Prusa Mini+ and Prusa i3 models are some of the most ubiquitous printers (figure 3). They are extrusion-based printers which operate by heating a plastic material through a tube (filament) and distributing the heated material on a platform layer by layer, until it takes the full form of the object. The material is Polylactic acid (PLA) and can be heated at a low temperature. It is a robust, low-cost, and biodegradable material. Xometry prints using this method.
The Formlabs 3 printer operates with an entirely different method (figure 4). It uses stereolithography (SLA), which is a type of additive manufactory technology employing resin 3D printing. A light source like a laser or projector heats and cures liquid resin at a high temperature into hardened plastic in the shape of a 3D model. SLA printers have the ability to capture the highest resolution and most accurate details of objects, along with smoother surfaces and more complex geometries (size and shape of the print).
Preliminary Results Printing with Xometry and the Medieninformatik Lab:
As apparent in figure 5, three different printing methods yielded three vastly different results. On the far left of the image is a print of the seal impression using a Prusa Mini+. As is evident, the fine details of the inscription of Nehi were too high resolution for the printer to capture with accuracy. The inscription is not legible and overall, the surface and geometry of the object are not clean. The middle print is of the seal impression from Xometry. Even though Xometry used a PLA printer (like the Prusa) the print is of a higher resolution, and the geometry of the object is more accurate. The surface is smoother and the inscription, while not perfect, is legible. Lastly, the far-right print is from the Formlabs 3 printer. This by far, is the highest quality and highest resolution print! The inscription is very legible, and the geometry of the object is extremely accurate. The surface is also smooth, extremely detailed, and shows no signs of lumps or imperfections in the raw material. While the Formlabs 3 printer is a more time-intensive and expensive process, the cured resin clearly is the superior material to capture intricate and complex details of smaller objects (figure 6).
In terms of the heart scarab, the differences between prints are less stark but still significant. As evident in figure 7, the Xometry print (on the left) and the Prusa Mini+ print (on the right) are similar in shape and detail. The Prusa print has a smoother and cleaner surface, and slightly more legible details near the top of the scarab.
The bottom of the scarab demonstrates the biggest difference between the two prints (figure 8). The inscription was not captured at all on the Xometry print (left), due to the direction in which the print was oriented. If the print is rendered layer by layer with the bottom of the object flat on the printing platform, then any detail on the bottom of the object will not be captured. However, with the Prusa Mini+ print (right) the object was printed at an angle, and the result is a legible inscription (figure 9).
From these preliminary printing exercises, it was fascinating to see just how different prints of the same object can turn out given the variety of available printers, raw materials, and approaches. Clearly the various methods explored here have their pros and cons. 3D printing methods must be tailored to the specific goals of the project and qualities of the object/3D model. Trial and error, if you have the available resources and time, is a terrific way to start!
The Significance and Broader Impact of 3D Modeling and Printing
As an archaeologist who is interested in digital technologies, I am asked all the time (by fellow archaeologists and non-specialists alike), what is the purpose of making 3D models of artifacts that already exist? What keeps us from creating glorified toys that just sit and gather dust on shelves?
The truth is….3D modeling applications in archaeology is a means of addressing several unique problems of studying the ancient past. Firstly, 3D prints of archaeological objects that can be handled and shared without any risk of damage to the original artifact is invaluable. For objects that are restricted to museum collections or excavation archives, 3D models increase the accessibility of the archaeological record, not only to scholars in different regions, but also to members of the public. High quality 3D models that capture valuable information such as inscriptions and technological means of production can be used as tools in public outreach and education. In fact, our PI Julia Budka just demonstrated this during her recent appearance on the wildly popular children’s show, “1, 2, oder 3?” On a show dedicated to ancient Egypt, she brought our Xometry print of the seal impression to teach children that even objects made of seemingly quotidian materials like mud can be extremely important to archaeologists. 3D models expand and diversify the types of environments in which objects can be used in teaching.
Here is a link to the full episode if you would like to check it out!
Lastly, 3D printing can be used alongside other experimental archaeological approaches. For example, our graduate student Sofia Patrevita is studying goldsmithing techniques in Nubian jewelry making, including the lost wax technique. See her recent blog post here. The 3D printing lab at LMU has the ability to print objects in wax (among other materials), which could allow us to experiment with recreating jewelry in various stages of production, giving us insight into the chaîne opératoire of Nubian goldsmithing. Sofia and I are looking forward to exploring this possibility in future collaborations!
A huge thanks to the Medieninformatik Lab at LMU for access to their printers and resources, and especially to Boris Kegels for providing the access and printer training. Thanks also too Christine Mayer and Prof. Dr. Nicola Lercari of the Institute for Digital Cultural Heritage Studies at LMU for helping facilitate this collaboration!
Stay tuned for an update on our most ambitious 3D printing project yet, a to-scale reproduction of Khnum-mes’s shabti from Sai Island!
