APPEAR Project – APPEAR Interim Meeting at the British Museum

Hi! This is Eve Mayberger with an update about the Ancient Panel Painting: Examination, Analysis, and Research (APPEAR) project. During the past few months, I have been investigating the three Fayum mummy portraits in the Penn Museum with digital photography, multispectral imaging (MSI), portable x-ray fluorescence (pXRF), x-ray radiography, and reflectance transformation imaging (RTI). A few weeks ago, I had the opportunity to travel to London and represent the Penn Museum at the APPEAR interim meeting.

APPEAR Project, British Museum

The meeting was jointly organized by the Getty and the British Museum. Representatives from invited institutions were asked to present an update on the current research of Fayum mummy portraits in their collections. Although not every participating institution was able to send a representative, there were individuals from the United Kingdom, Europe, and the United States. The group included conservators, conservation scientists, art historians, and artists who were all personally engaged with different aspects of the APPEAR project.

APPEAR Project, Presentation at the APPEAR interim meeting

For the APPEAR research at the Penn Museum, I talked about our non-destructive analysis, imaging, and outreach initiatives for the three portraits in the collection. I focused on some unusual observations I recorded with MSI on the Portrait of a Young Man (E16213). My presentation was well received and inspired a lively debate about MSI terminology and standardization protocols.

APPEAR Project, Penn Museum Presentation

Between talks and over meals, I was able to chat with other APPEAR participants about their various institutions and current research initiatives. At the end of the meeting, the British Museum was kind enough to give us an extensive tour of their new conservation labs and scientific research department. It was an amazing experience and I was honored to present our research at the Penn Museum to the larger APPEAR community.

Say hello to Djed-Hapi

I apologize in advance for those of you who might be waiting for more updates on the Middle Kingdom boat model I started working on a while ago. That object was put aside temporarily to make room for all the pieces that recently came into the Artifact Lab when we deinstalled our Mummy Room and Secrets and Science galleries. While the cases in those galleries were reinforced to better withstand vibrations from the hospital construction next door, and new mounts designed and made for many of the objects, we were working hard to assess the condition of all the pieces, and treat them as necessary before the galleries reopened. This was a pretty short turn around, and several of us in the Conservation Department here chipped in to help make sure every object was looked at properly before they went back on display.

While most of the objects are in good condition, and only needed a little surface cleaning to remove accumulated dust, some needed much more complicated and detailed treatments. I began by looking at our mummy Djed-Hapi, who is the first mummy you see when you enter the Secrets and Science gallery.

As you can see, In the original case design Djed-Hapi rests in his coffin base, while the lid is suspended above on a metal shelf. Unfortunately, the coffin lid will not be returning to the case, as the shelf it used to rest on cannot withstand the level of vibrations which may occur. Don’t worry though! It will remain in the Artifact Lab and be conserved as part of a future treatment project.

As for Djed-Hapi himself, we know that he dates to the Ptolemaic period (305-30 CE). We know his name, and in fact the names of several of his family members, because of the hieroglyphs written on his coffin lid. Here is an archival image of Djed-Hapi’s coffin lid and base, and you can see all the text written on the lid:

He was x-rayed in 1980, and from these images we can tell that he was a man who lived into his 50s before he died. While these old x-ray images were serviceable, we decided to re-x-ray him in our digital x-ray suite here at the museum, because we felt we could get a better level of detail with the digital system.

Study of these x-rays revealed some very interesting facts about Djed-Hapi’s mummification. His head is completely detached from his body, cleanly separated between two of the vertebrae in his neck.

This was not his cause of death, but happened during mummification, and seems intentional. Starting in the Ptolemaic Period, the mummification process shifted from removing the deceased’s brain through the nose, to removing it through the base of the skull. The x-rays also show that Djed-Hapi’s nasal cavity seems to be intact, so this change in the mummification process may be the reason Djed-Hapi’s head was removed, then replaced and carefully wrapped with the rest of the body. The decapitation is not visible from the exterior, and in fact his head and neck area are quite stable.

The x-rays also reveal a bit about the condition of Djed-Hapi’s body underneath the wrappings. His skeleton is well-articulated (except for his head of course), including all his finger and toe bones, and you can even see the soft tissue preserved, which implies the body is in good condition. However, a closer look at his ankles shows that there is a rather large gap between the distal ends of his tibiae (shin bones) and his tarsals (ankle bones). While there is no evidence of damage to the exterior of the linens, we can tell whenever we have to move the mummy that the ankle area has some movement. This is an issue which could lead to further damage in the future, so careful handling is required.

Next up, I’ll discuss the conservation treatment of Djed-Hapi’s mummy, and his coffin base.
