Archaeological Research

From the Archives 19 — April 2017

BY SEBASTIÁN ENCINA, Museum Collections Manager

Around the world, the Kelsey Museum is known as the home for the excavations at Karanis, which the University of Michigan conducted between 1924 and 1935. The collections and archives from this expedition continue to fascinate us, and they provide a wealth of information we continue to revisit through many projects. Scholars from everywhere look to the collections, both artifacts and archives, to further research and our understanding of Egypt under Roman power. Here in Ann Arbor, the collections play an important role with classes and exhibitions.

When Francis Kelsey was finding funding for the Karanis expedition, he was actually initiating a fund to excavate at multiple locations. In 1924, U-M went to Karanis, as well as Antioch and Carthage. These latter two sites turned out to have single-season excavations, as the focus was placed on Karanis due to its rich artifact and papyrological finds. U-M stayed there through 1935, when finally excavations were completed. However, the team did not excavate only at Karanis during this time, as they ventured to other sites while in Egypt. In 1931, the team went to Soknapaiou Nesos (Dimé), and in 1935 they excavated at Terenouthis. Each of these also turned out to be a single-season excavation due to a number of reasons.

Since 1931, the Kelsey has still housed the archives and artifacts from Dimé. Not nearly as plentiful as Karanis, it still provides a wealth of information for archaeologists working at Dimé today. These archives were deposited within the papers of the Karanis Expeditions, not even separated into their own collections. Because of the tremendous attention paid to Karanis, the Dime archives are not as often studied.

Over the past academic year, Classics professor Arthur Verhoogt made an effort to focus on Dimé again. Prof. Verhoogt worked with two UROP students, Bianca Gallina and Josiah Olah, to revisit this collection, study what they could within the Kelsey as well as Bentley Historical Library. The two students scoured the letters, papers, drawings, and maps, and made note of what they found that would be useful to researchers.

For this month’s From the Archives, we present some of the items they digitized. Much like Karanis, the excavations at Dime resulted in some impressive maps. These will likely look familiar to some readers, as the style and look of these maps are similar to those from Karanis. The maps include triangulation points, cross sections, and overview of the excavation site. Having these on hand will assist us in understanding the work carried out at Dime nearly 90 years ago. This is even more important to our colleagues who continue working at the site. This Spring term, the students will continue digitizing more archival materials, including house drawings. In Autumn, the Dime excavators will visit Ann Arbor to further research the materials housed here. By then, we hope to have everything digitized to provide even greater access.

Low-tech adhesive testing for Egyptian polychrome limestone

BY CAROLINE ROBERTS, Conservator, Kelsey Museum of Archaeology

One of my favorite conservation activities is researching practical solutions to complex condition problems. Example problem: how to stabilize flaky, powdery paint on deteriorating Egyptian limestone artifacts. The solution? Some kind of adhesive. But which kind would work best in an outdoor environment on salt-laden painted stone?

To figure this out I took a look at published information on the treatment of painted Egyptian limestone sculpture and wall paintings. There’s a lot of information out there on this topic, and I wanted to see for myself how some of the adhesives tested by conservators and scientists performed on a painted, salty limestone surface. The Kelsey Conservation Lab has limited equipment for this type of research, although we often partner up with labs that do (check back with the Kelsey blog for an upcoming post on our collaboration with UM’s Aerospace Engineering Department). One thing I could do in-house was to create mockups of the problem surface to approximate how each adhesive might perform in situ.

 

Creating mockups that accurately represent the materials and conditions of an ancient paint surface required some creativity. I used travertine tiles as a base, and soaked half of them in a solution of sodium chloride, or halite. This type of salt is present in much of the soil in Egypt, and has been shown to have an impact on adhesive performance. Stone was often covered with a “preparation” layer (or layers) of plaster before paint was applied, so I applied Plaster of Paris to each tile. I then applied a layer of red ochre in gum Arabic — a plant-derived binder used in ancient Egyptian wall painting — with a high pigment-to-gum ratio representing the often diminished state of ancient binders on polychrome limestone. A section of each material — stone, plaster, and paint — was left visible on each mockup.

I applied five different adhesives to the tiles, leaving a number of them untreated as a control. I recorded their working properties, absorption, and resulting color changes, and then placed them outside to see how the adhesives fare in an exposed environment on both salty and un-salty mockups. From this low-tech experiment I hope to determine, from a practical angle, which adhesive to use on artifacts both at the Kelsey Museum and in field settings.

RTI at Kurru!

JANELLE BATKIN-HALL, Graduate Intern in Conservation

I’ve just returned from a fantastic six-week fieldwork experience at the El Kurru archaeological site in North Sudan. There, Kelsey conservator Suzanne Davis and I documented ancient figural and geometric graffiti in a funerary temple at the site. Each day, Suzanne and I would make our way through a maze of mudbrick alleys to the edge of the village, where the funerary temple and several royal burial tombs and pyramids are located in the desert.

We photographed  the graffiti using a process called reflectance transformation imaging (RTI) (fig. 1). RTI is an excellent technique for documentation because each pixel records surface texture in addition to color. Since sandstone is subject to ongoing disintegration and loss, the resulting RTI images provide an excellent record of the graffiti’s current condition, as well as a highly detailed image of the column’s surface texture.

The Kurru graffiti were documented using highlight image capture where the camera remains fixed and a portable flash is moved at intervals which create a dome of light over the surface.  In a single photo sequence of one object (or in this case, graffito), approximately 48 digital images are taken. Two reflective black spheres are also fixed within the image frame, and the reflection of the flash on these spheres allows the processing software to calculate the light direction for each image. The resulting images are combined with software, resulting in a single file. In this file, the viewer can move the light source across the surface in order to examine the surface details and topography from any angle (fig. 2).  As a result of using this technique, 64 “new” ancient graffiti were positively identified and additional surface details became visible. In a couple of instances, a graffito was initially misidentified. For example, in 2015 a particular graffito was identified as an arrow. After performing RTI, it was clearly a human figure.

For me, this was a great experience because I was able to use a technique I recently learned in graduate school. Being able to apply it onsite and share the results with our colleagues was very rewarding.

Mt. Lykaion Excavation and Survey Project study season

BY DAN DIFFENDALE, PhD student, Interdepartmental Program in Classical Art and Archaeology, University of Michigan

Mt. Mainalon
Mt. Mainalon above the village of Kardara.

I spent the first three weeks of June in Greece, working with the Mt. Lykaion Excavation and Survey Project. Although the project last conducted fieldwork at the Sanctuary of Zeus Lykaios on Mt. Lykaion in western Arcadia in 2010, we have been busy every summer since then studying the excavated materials. In excavation years, we rent private houses in a village close to the site; during study seasons, we stay in an off-season ski resort in eastern Arcadia, in order to be close to Tripoli, where the artifacts are housed. From Kardara it’s a thirty-minute van ride to our apotheke, or storeroom, where we study the materials almost every day (but never on Sunday). The study seasons witness a wide range of scholars and specialists coming and going as their schedules permit; among others, we have experts in animal bones, roof tiles, coins, and numerous varieties of ancient pottery, including Neolithic, Early, Middle and Late Bronze Age, Iron Age, Classical, Hellenistic, and Roman. Of course, this study could not proceed without the heroic efforts of our registrar, who is responsible for the organization of the apotheke and all procedural matters relating to the artifacts, along with her team of assistants, who do whatever assisting needs to be done.

This season I have been assisting one of the project’s directors in the study of the Late Bronze and Early Iron Age pottery, as well as preparing a final report on the stratigraphy of one of the project’s trenches on the peak of Mt. Lykaion. One of my goals this season has been looking for matches or “joins” between the tens of thousands of broken pieces of pottery from the trench. Although it is inherently satisfying to find such joins, a successful outcome is by no means guaranteed; it’s like playing a puzzle without a box-top picture to compare to, and with most, if not all, of the pieces missing. Despite the frequent frustration, it’s an important activity; knowing if there are pieces of the same pot scattered in different parts of the trench helps us to understand the formation processes of the site. If ancient people deposited a whole pot on the mountaintop, but we find broken pieces of it in different areas of our excavation, we deduce that it must have been broken and had its pieces scattered by one or more subsequent events. These events might be later human activity, animal disturbance, natural phenomena like earthquakes or frost heaves, or some combination of these. Given that the altar where we excavated has evidence for human activity spanning some three thousand years or more, from the Neolithic to the Hellenistic period, or from before 3000 BCE down to the 1st century BCE, followed by the two thousand years from then to now, it’s not surprising that things got so mixed around!

Exam time for archaeology graduate student

BY CAITLIN CLERKIN, PhD student, Interdepartmental Program in Classical Art and Archaeology (IPCAA), University of Michigan

Studying for exams
A confused pile of books for term papers and IPCAA archaeology qualifying exams that I need to cart back to the library.

The end of the “winter” term at U of M marks not only the end of classes and preparations for summer work, whether in the field or stateside. For IPCAA students in their first three years, the end of the winter term also marks IPCAA exam time.

IPCAA students take a lot of exams before advancing to PhD candidacy: beyond exams in courses, we have to pass four language exams (Latin and Greek, and German and French or Italian), a qualifying exam in ancient history, and archaeology qualifying exams in three major areas (Egypt and the Near East, Prehistoric Aegean and Greek, and Etruscan and Roman), and preliminary exams (preliminary, that is, to a dissertation). The language exams occur throughout the school year, but the other three exams occur just after the end of each academic year. First-years take the ancient history qual; second-years take “Quals” (the archaeology exams); and third-years take their prelims, on topics they’ve chosen in consultation with faculty members. Thus, if you visited the Kelsey during the first week of May, you may have seen some dazed, ermm, I mean, well-rested, calm, and chock-full-of-knowledge-looking graduate students wandering around the building.

The goal underlying Quals is ensuring that IPCAA students gain a foundational understanding of the major subject areas of our field, which will allow them to develop their research focus informed by knowledge about major sites, monuments, and theories while also equipping them with the resource base to teach about these different areas. As such, studying for and taking Quals is an exercise in solidarity and solidification. Solidification, because we are asked to consolidate our understanding of facts, developments, theories, and trends so that we can redeploy all these things to answer new questions. Solidarity, because taking Quals is an experience (or labor) undergone by individual cohorts together, but that also unites IPCAA cohorts across time, on what I imagine is a sociological or ritual rites-of-passage kind of level. Not only have we learned similar material, but we’ve all sat and written essay after essay, slide ID after slide ID for hours (twelve actually), after months of studying and anticipation. As a second-year in IPCAA, I, with my three cohort-mates, just took Quals. Afterward, when corresponding with an IPCAA alumna with whom I work in the field about our upcoming fieldwork, I sensed a sigh of relief in her congratulations to me for having the exam in my rearview mirror.

Before entering IPCAA, I received an MA in Latin from the University of Georgia, which involved passing a “Reading List Exam” in March of our first year in the program. In the frenzied studying for that exam, my cohort quizzed each other on writers, works of literature, and historical events. Since then, I have not forgotten that the Roman playwright and Stoic Seneca was forced to commit suicide by Nero in 69 CE, along with his nephew, the poet Lucan, because a classmate came up with the mnemonic soundbite that Seneca and Lucan “died in each other’s arms” (not strictly true but will be forever ingrained in my memory). Similarly, I think (or hope) I will never forget my go-to examples of the mixing of the Doric and Ionic orders on temples (Temple of Athena, Paestum), or where the Stone Law Code Stela of Hammurabi was found (Susa) and why that matters. Thanks, cohort-mates, for getting me through this IPCAA milestone!

Life on a Fulbright: Fieldnotes from Naples

BY JENNY KREIGER, PhD candidate, Interdepartmental Program in Classical Art and Archaeology, University of Michigan, and Fulbright Fellow, 2014–2015

Since October, I have been living in Naples, Italy, where I have been conducting my dissertation research with the help of a grant from the US-Italy Fulbright Commission. The Fulbright Program supports academic exchange programs for American and international students, faculty, and researchers, and Italy is just one of many countries that participate in a bilateral Fulbright Commission.

Naples overview
A view of Naples from a hilltop castle. That very straight street at the lower left is one of the Roman decumani, still in use as a main road today.

The beauty of the Fulbright program is that it gives me the time and resources to do my research abroad while encouraging me to serve as a “citizen diplomat,” representing my country and learning about my host country at the same time. I wanted to immerse myself in the culture of Naples, so I rented a room in an apartment with Italian roommates. As it turned out, these were not just any roommates: they are the managers of an experimental theater company (TeatrInGestAzione; see link below). Their principal project every year is Alto Fest, a performing arts festival that puts artists into unusual venues in Naples — terraces, garages, kitchens, even the airport — offered for free by the owners. Artists come from around the world to create and adapt works for these spaces throughout the city, encouraging audiences to explore and connect with Naples on an intimate level. In our day-to-day life in this rooftop apartment, my roommates show me how the arts and cultural heritage can be used for social development and urban renewal in a concrete and personal way.

My roommates are not the only young Neapolitans using culture and heritage to change their city for the better. Through my research on the catacombs of Naples I have come into contact with the people of La Paranza, a social cooperative organization that is developing the catacombs and other heritage sites of the Rione Sanità as tourist destinations and sources of employment and local pride. La Paranza organizes concerts, art exhibitions, and other special events in addition to regular tours of the catacombs, and their programs attract locals and visitors alike. Centuries ago, the catacombs were important sites of cult and memory, and in their modern context the catacombs continue to shape local identity and daily life.

Naples catacombs

Finally, I want to share a few words about my research itself. My dissertation examines three major Italian catacomb complexes (in Rome, Naples, and Syracuse) to learn about the funerary industry in late antique urban contexts. Specifically, I am looking at inscriptions, paintings, and architecture in catacombs for clues about how funerary labor was organized, how laborers balanced customization and “mass production” in their work, and how materials (like marble slabs) were recycled and traded for funerary use. In practical terms, this has meant visiting sites, museums, and archives to study surviving materials and analyzing what I find using an array of philological, art historical, and archaeological methods. One of the broader goals of my dissertation is to consider the roles that ordinary workers played in the shaping of ancient culture, and it has been an invaluable part of this process to get to observe small organizations shaping the culture of a major modern city.

Letter from the Met

BY EMMA SACHS, PhD candidate, Interdepartmental Program in Classical Art and Archaeology and Museum Studies, University of Michigan, blogging from New York, where she is a Bothmer Fellow at the Metropolitan Museum of Art.

This year I have been conducting research and writing at the Metropolitan Museum of Art as a Bothmer Fellow in the Department of Greek and Roman Art. I vividly remember the day I found out I’d be coming to the Met — February 21, 2014 — because that was the day Pompeii opened in IMAX. Expecting that this would be a major box office hit, I preordered tickets and dragged my extremely amenable friend to the theater 45 minutes early to stand in line — only to be told by a confused theater employee that there was no line, and the theater would be available about 10 minutes before the show. We should have lowered our expectations when a woman in the restroom loudly announced that “If anyone is planning to see the movie Pompeii, don’t do it!!” But sometimes hope is blind and academics naïve — especially when their field of study is featured in 3D. Needless to say, it was terrible. Vesuvius couldn’t have erupted too soon, and even when it finally happened, the IMAX effects were mediocre. If we had to sit through a poorly crafted story, we could at least have been rewarded with a few more fiery rocks flying at our faces. That evening I was busy explaining my disappointment over the phone to my parents when the fellowship offer from the Met appeared in my inbox. So it wasn’t a bad evening after all.

I moved to New York in August and started at the Met in September. The Bothmer Fellowship was awarded in support of my dissertation research, and accordingly most of my time has been spent closely studying the museum’s fantastic collection and writing at my desk in the Watson Library, the museum’s central library. (The Met has 28 libraries in total!) I also routinely participate in talks, tours, and lectures arranged to introduce Fellows to the museum’s 17 curatorial departments, its system of administration, and active projects.

The focus of my research is wall painting from the Bay of Naples region, where the volcano Vesuvius erupted in AD 79 and buried much of the surrounding region, including the cities of Pompeii and Herculaneum and nearby villas in the countryside. While this disaster by no means “froze” this region in time, perfectly preserving it for posterity, the volcanic debris did help to preserve a considerable amount of wall painting, protecting it from exposure the elements. For this reason, the majority of the corpus of Roman fresco comes from Campania, and any systematic study ever done that pertains to “Roman” wall painting has its roots in this material and in this region. The Met has the best collection of Roman wall painting in the Western Hemisphere, so it is naturally a magnet for wall painting specialists. I am particularly interested in the museum’s paintings from the Villa of Publius Fannius Synistor in Boscoreale, which was excavated in 1899–1902. In 1903, many of the villa’s frescoes, mosaics, and smaller finds were sold at a Paris auction and dispersed to numerous institutions and private collectors around the world. Nineteen fresco sections were purchased by the Met in 1903, and they have been a highlight of the museum’s collection ever since. I should note that a few small finds eventually made their way to the Kelsey Museum, including bronze hardware, agricultural tools, and a stone rotary mill on display on the Kelsey’s second floor.

While my experience thus far has been very fruitful for my dissertation, I have also learned a great deal about the museum and its objects. The great breadth and depth of the museum’s collection of antiquities — dating from the fifth millennium BC to the fourth century AD — allows for an encyclopedic display, organized by time and region (much like the Kelsey’s installation, if a bit more expansive). While I came to the museum a little skeptical of this linear march through time, I have observed that it is accessible to many different kinds of audiences: easily comprehensible to casual visitors and yet helpfully contextual for specialists. One of my favorite Fellows’ activities was conducting a tour of the Greek and Roman galleries to about 20 other scholars. This allowed me to explore the Met’s institutional history and the prominent role the art of antiquity has played since the museum’s founding in 1870. Indeed, the first object accessioned by the Met was actually a Roman sarcophagus from Tarsus in southeast Turkey. In 1870 it was donated to the museum — which at that time only existed on paper — as a gesture of diplomacy by the American vice-consul in Tarsus, Abdo Dabbas. The most sizable acquisition made by the museum in the next thirty years was that of the Cesnola collection, about 35,000 ancient objects from Cyprus, purchased from General Luigi Palma di Cesnola in 1874 and 1876. This collection formed the core of the Met’s early holdings, and in fact the general himself became the first director of the museum in 1879, holding the position until his death in 1904. While as a Fellow I have learned so much about the Met and its collections, as always, the Kelsey is never very far out of sight. Some pieces from the Cesnola collection eventually made their way to the Kelsey and are on view in the Cypriot case on the first floor.

Camping and Kanka Cola: Life at Labraunda

My fieldwork experience was crucial for my decision to apply to graduate school. During my junior year at Brown University, I had the opportunity to become involved in a new archaeological project directed by Prof. Felipe Rojas, who is at the Joukowsky Institute for Archaeology and the Ancient World at Brown. Since 2013, I have been part of the Brown University Labraunda Project (BULP). BULP is concerned with the rural sanctuary of Labraunda in ancient Caria, now modern southwestern Turkey, and is part of the greater Labraunda Archaeological Project directed by Dr. Olivier Henry.

In antiquity, Labraunda was a sanctuary dedicated to Zeus Labraundos, and people from cities to the north and south came to worship the local deity at an annual festival. The sanctuary is known for its monumentalization by local satraps under the Persian Empire in the mid-4th century BCE: Mausolos (most famous for his Mausoleum, a wonder of the ancient world, located in Halikarnassos, now modern Bodrum) and his brother Idrieus. The current objective of the project is to study a monumental fountain house that lies just outside of the sanctuary. Before our studies, the fountain was largely overlooked because it does not conform to traditional classical architecture, even though its importance is clear due to its position between the two entrance gates to the sanctuary. Our studies suggest that the fountain was built in the mid-4th century BCE and used in some capacity through the Christian period. It is the largest fountain house at Labraunda, and it would have provided rest and refreshment for visitors after a long journey.

I enjoy the intellectually stimulating (and physically tiring) research, but even more so I love learning and living in the Labraunda community. Multiple groups work at Labraunda at a time. In addition to our Brown team, I interact with Turkish, French, and Swedish scholars on site. During the week, we camp about a five-minute walk from site, so we do not have the same accommodations we would have if we were staying in a hotel in the closest town (i.e., we have limited electricity and two working toilets). When I tell this to people, they often describe it as “roughing it,” but with such great company and views of the mountains and stars, I can’t complain at all. I have also enjoyed working with local Turks in the trenches. Language is often a barrier, and I am on my way to learning Turkish. However, we often find things to chat about, mostly the weather (Bugün hava çok sıcak — Today the weather is very hot!), and we have fun as we work together. Some of the younger workers have affectionately dubbed our team members kankalar, similar to “bros” in English, and we have named our daily soda breaks “Kanka Cola.”

When I first heard about this project, I never could have imagined where it would lead me. Now as a first-year student in IPCAA, I plan to specialize in Western Anatolia and continue fieldwork in Turkey. The excavations of the monumental fountain house are almost complete, but I look forward to seeing where BULP’s future studies at Labraunda will go.
