An Answer to the tough question: What is your favorite thing?

A question we often get asked in the Artifact Lab is, “what is your favorite thing that you have worked on?” Usually I find this question hard to answer because we work on so many different and fascinating objects, but at the moment, it’s a no-brainer. The trumpets from the Democratic Republic of Congo that are slated to go into the new Africa Galleries are by far some of the coolest objects I have ever worked on. As an example, here is AF5211:

This trumpet is carved from elephant ivory (identifiable by the clearly visible Schreger lines).

There is some type of reptile skin wrapped around one end and stitched together on the side, and animal fur that literally makes this object look like a rock star.

All these details make this object beautiful, but what makes it special is what is hiding beneath the skin. In a few spots where the reptile skin has shifted you can glimpse repairs.

The repairs are even more visible from the interior of the object. It seems that at some point, probably when this object was in use, the ivory split. It was then repaired by drilling holes into the ivory and stitching it together. There is also some type of resinous mixture that was put into the join.

The reptile skin may have been added to both hide the repair and support it so that the object could continue to be used. It is these glimpses of the life of the object that make it so special. It tells not just the story of its craftsmanship but also the people who used it and cared for it.

To see this object in person, visit the new Africa Galleries when they open in November of this year!

A closer look at our stola coffin lid

In my last post about this late 21st/early 22nd stola coffin lid, I referred to it as eye candy.

This coffin is beautiful, and we could discuss how nice it is to look at all day. But in this post, I’m going to focus on some of the more subtle, somewhat less-attractive (but perhaps even more interesting) features that I’ve discovered about this coffin lid as I’ve begun to work on it. In fact, on Friday I spent awhile discussing some of these details with a group of conservators and interns from the Philadelphia Museum of Art (PMA). As I mentioned in my last post, although this coffin has been on long-term loan to us since the 1930s, it still technically belongs to the PMA, so I am carrying out my treatment in close consultation with one of their objects conservators.

I always appreciate the opportunity for professional exchange, and I was happy to be able to discuss my plan, including materials and approaches with them. This discussion energized me to get started with the treatment, and that is exactly what I did, almost as soon as they left.

One thing that I noticed in my initial examination is that this coffin lid has been worked on before. There are residues of old adhesives in areas, including an adhesive mixed with a sawdust-like material, especially around the foot of the coffin.

I have seen these same types of repairs on at least one other coffin in our collection, and while there is no documentation of them, I am suspicious that this treatment was carried out in our museum soon after we acquired this coffin, but long before our conservation lab was established 49 years ago.

The foot of the coffin has another type of repair as well – there are 2 brackets that are held on with screws on the underside of the foot, apparently to secure some of the wood components. This whole area moves when handled, so the brackets and screws will have to come off so that I can better assess what is going on.

There is some very powdery material associated with areas of damage, especially on the face, which appears to be partially due to deterioration of the mud plaster, but also may be due to insect activity. I’ll have to investigate this further over the course of the treatment.

And then there are some materials included in the mud plaster, including some course linen threads and even a leaf, which I am documenting as I work to clean the surface.

The next time I post images of this coffin lid, it should be a lot cleaner, as I plan to complete the initial surface cleaning within the next week. More soon about this, and other observations and developments in the treatment.
