Summer 2016 Conservation in South Abydos

I just returned from spending almost 3 weeks in Egypt on the Penn excavations in South Abydos. This was my second time on the project (I went for the first time last December/January). I specifically returned to continue work on the wall paintings in the burial chamber of pharaoh Senebkay and to provide additional conservation support for the project during my time there, which included object treatment, documentation, and block-lifting an extremely fragile wooden coffin fragment.

I joined Dr. Josef Wegner (Joe) and his team at the end of their time in the field, so by the time I arrived, the season was well underway and everyone was doing their best to keep from melting in the exceedingly high temperatures and intense sun of the Upper Egyptian desert climate (think, getting up before sunrise to start working and during the hottest part of the day, sitting in front of a fan in a dark room).

There are times of the day when all you want to do is find a cool place to rest.

Most of my days in Abydos were spent primarily in the field, working on the painted surfaces and limestone blocks in the burial chamber of pharaoh Senebkay. The work involved continuation of cleaning the limestone blocks, paint consolidation, stabilization of flaking limestone, and inpainting select missing areas of the painted decoration.

I was fortunate this season to be joined by conservator Danny Doyle, who had worked on Senebkay’s burial chamber exactly a year ago, and who was also returning to Abydos for a second time. We had additional conservation support from the Egyptian conservation inspectors.

This season we also made the decision to open up the tomb chamber adjacent to the burial chamber to block lift a very fragile wooden coffin fragment. This fragment was left in place in previous seasons due to its fragile condition. Danny and I stabilized it, block lifted it, and we brought it back to the dig house to further clean, stabilize, and document.

In addition to the work in the field there was other work to do in the lab, including cleaning, consolidating, and mending fragments from a limestone stela, also from Senebkay’s tomb.

Following the conservation treatment, I assisted Joe in RTI imaging of the stela, capturing overall shots, and then details of specific areas of interest. For those unfamiliar with RTI (reflectance transformation imaging), it is a computational photographic method where you capture a bunch of images of an object from a fixed position while you move the light source around the object, illuminating it from different angles. An interactive RTI viewer tool allows you to use these images to enhance the surface features of an object which often reveals details not observed under regular lighting conditions. Dr. Jennifer Wegner worked on the translation of the text on this stela this season, and capturing these RTI images will allow this work to continue back at the Penn Museum. (More on RTI and how we use it here.)

Here is our amazing RTI setup - as you can see, Joe was happy that everything appears to be working properly (at this moment anyway).

I am so grateful that I had the opportunity to return to Abydos, to continue to learn about this complex site, and to contribute to the long-term preservation of the finds. Besides the work, and our efforts to stay as cool as possible, we also played a lot of bocce in the evenings, and even celebrated a couple birthdays!

Finally, I have to say that while being in Egypt was really exciting, there was plenty of exciting work happening right here in the museum the entire time I was gone. Since I left, nearly both of the large-scale Buddhist murals in the Chinese Rotunda have been taken down (thanks to the hard work, sweat, and hopefully no tears from an amazing team of conservators and riggers), the Egyptian storage move project is clipping along at an incredible rate, and there has otherwise been a whirlwind of activity in the department.

There isn't much left of those murals in the Rotunda. The left one is completely gone and the right one will be gone by next week.

Kudos to all of my colleagues for keeping this all up while also holding down the fort in the Artifact Lab in my absence!

 

 

Report from the field: Conservation in the burial chamber of king Woseribre-Senebkay

I’m back from Abydos! I thought I’d follow up on my last blogpost about my time in the field with some more specific information about the conservation work I was carrying out in the burial chamber of king Woseribre-Senebkay.

King Senebkay’s tomb was discovered and excavated in the 2013-2014 winter field season. The tomb dates to the later Second Intermediate period, to the Hyksos era, ca. 1650-1600 BCE, is in close proximity to the tombs of Senwosret III and Sobekhotep IV, and is part of a larger cluster of Second Intermediate period tombs. It consists of 4 chambers, the final being a limestone burial chamber with painted decoration. Based on observations and interpretation by Drs. Wegner and Cahail, the tomb was built fairly quickly and the painted decoration does not appear complete.

Another important feature of the burial chamber is that the limestone blocks were reused and much of the previous decoration is still visible. The blocks were disassembled from a group of mortuary chapels of high-ranking officials of the mid-late 13th Dynasty.

The previous decoration on the resused blocks is visible in many areas (indicated with red arrows in the image on the left) and in some areas there is still paint remaining (circled on the right)

I won’t go into any more detail about the significance of Senebkay’s tomb and these features – this has been written about extensively elsewhere and I’ll provide links for more information below.

I was asked to join the team this season to work on the painted decoration in the burial chamber. During the previous season, the burial chamber needed to be stabilized (new mortar joins between blocks and replacement of missing blocks). In order to protect the paintings, another conservator was able to carry out some consolidation of the paintings and then covered the painted areas with cyclododecane and aluminum foil. At the end of the season, the tomb was backfilled.

My goal for this season was to continue paint consolidation, to reattach detached stone fragments, to inpaint the new mortar fills in select areas, and to prepare the tomb for backfilling. A permanent structure will be constructed around the tomb later this year, but in order to protect the tomb until this can happen, it needed to be filled back in with sand and completely covered.

When I arrived on site, the first thing that I did was to remove the aluminum foil from the paintings and to examine them carefully. Due to timing/logistics it was not possible to uncover them before I arrived, so what I found under the foil was that there was still a lot of cyclododecane left on the surface of the paintings.

I’ve never mentioned cyclododecane (CDD) on this blog before. CDD is a cyclic hydrocarbon (C12H24), a solid wax that slowly sublimes at room temperature and it is used as a temporary consolidant, to protect fragile and sensitive surfaces during treatment, and it has become a very useful material for archaeological conservators to help with lifting fragile materials in the field. Check out this link for a video to learn more about it and how it is used.

While I tried several techniques to speed up the sublimation of the CDD in the end I wasn’t able to remove it everywhere because the painted surface below was so fragile and susceptible to abrasion. So, like anyone who has worked on an excavation must do, I made it work! With the help of my Egyptian conservator colleague, I focused on consolidating all of the exposed painted decoration, on cleaning select areas, and on the repair and inpainting work I mentioned previously. I’m going to show some of this work in photos below.

Two days before we were set to leave, I consolidated the most vulnerable painted decoration with CDD, and then we carefully draped cotton fabric over all of the painted areas.

On our last day in the field, the chamber was backfilled with the sand that was removed from it previously, which will protect the tomb until the next season.

In addition to my work on site, I had the opportunity to work on some of the small finds from previous and ongoing excavations while in the dighouse in the afternoons, and the team generously made it possible for me to do some sightseeing during my time there as well, which rounded out the experience nicely.

After 3 years of working on the Egyptian collections at the Penn Museum, I was so grateful to have had this opportunity to go to Egypt – this experience not only allowed me to expand my conservation skills and understanding of our significant collection, but it gave me a much deeper appreciation for the exciting work that is ongoing in Abydos. I hope there will be an opportunity to return!
