Conservation treatment of Nespekashuti

Nespekashuti has been in the Artifact Lab for several months now and I’m finally ready to say that I’m (almost) finished with his treatment. I say *almost* because I saved one of the most difficult decisions for last – what to do about the gaping hole in his wrappings over his mouth. While I’m not quite ready to take the official after treatment images yet, I am going to post photos of how he looks in his nearly-complete status, along with explanations of what the treatment entailed. (I’ll also admit that posting these things on the blog helps me process my feelings about certain treatments, so thanks in advance for reading.) This post will focus on what I did with Nespekashuti, since I’ve touched on the treatment of his coffin in earlier posts here and here.

Let’s play a little game of spot the difference. I’ll post the image again below, circling areas on the before treatment image that I addressed during the treatment. Some of these things are easy to spot while others are more subtle.

Areas circled in red on the left image show some of the things that I addressed during the conservation treatment.

–  Let’s start from the bottom-up. During my initial examination I noticed that his feet were re-wrapped at some point with what looks like ancient linen. This re-wrapping probably happened before we acquired Nespekashuti in 1893 because in images of him from the Archives, the wrapping around his feet looks the same.

After some poking and prodding of this area, I decided to pull back the newer wrappings around his feet, which revealed this underneath:

I can see why someone decided to re-wrap them – the wrappings underneath are significantly deteriorated and darkened, and on the underside, there are some bones exposed. Since we do not know when the newer linen was added (radiocarbon dating might provide more information but it also might not, since it is quite possible that the newer linen is also ancient and could be as old as the original linen) I did not remove it completely. The only change I made in this area was to clean up all of the powdery, deteriorated linen underneath and to encapsulate the damaged wrappings around the feet with nylon bobbinet before putting the newer linen back in place.

– The next three red circles indicate areas where I realigned the linen and removed very deteriorated linen where it was fully detached. I actually did this all over the mummy, but these are areas where it is more obvious. In order to keep the realigned linen in place after making these adjustments, I encapsulated the mummy from his neck to his ankles in nylon bobbinet, toned with acrylic paint to camouflage it.

In the image above, you can see the nylon bobbinet draped over Nespekashuti’s body. I secured the bobbinet by tucking it under his body and placing Tyvek-covered Ethafoam blocks in strategic areas between the body and the inside of the coffin (the Tyvek was also toned with acrylic paint to camouflage the blocks).

– The red circle around the amulet on Nespekashuti’s chest is to indicate that I removed it for treatment. The amulet is actually not associated with the mummy at all – it was placed there for exhibition. The amulet is made of faience, dates to the New Kingdom/19th Dynasty, and was excavated from Aniba, Nubia by Charles Leonard Woolley in the early 20th century. It may be replaced for exhibition, but at this point I am not replacing it until our curators have a chance to weigh in.

– Finally, the most obvious part of the treatment is that I made a covering for Nespekashuti’s mouth. I continue to emphasize that the covering is fully removable – it can just be plucked out in pieces with tweezers if necessary. Here is a detail image showing the covering:

And here is another one from the right side comparing him before and after encapsulation and with the mouth covering:

You can see how this all looks from the front in the very first image I posted, but I’m focusing on how he looks from the side since he was previously displayed like this and this is most likely how he will be viewed when on exhibit in the future.

I made the fill by first covering his exposed teeth and surrounding bone with nylon bobbinet, then I layered the exposed area with Japanese tissue paper toned with acrylic paint, and finally I layered some toned bobbinet over the paper. All of the fill materials are tucked into the damaged linen around the loss in this area.

If our curators agree that the treatment is complete and that the fill can be left in place for now, I’ll call the treatment done and finish all of the after treatment documentation. I know that our visitors and readers of this blog were divided on what to do about the mouth, but I think we can all agree that Nespekashuti has received the much-needed care that he deserves. Please write in with any comments or questions you have about any aspect of this treatment! I will be sure to post something on the blog if we make any additional changes, or decide to scrap the mouth covering all together.

Putting the finishing touches on the shabti box

I have put a lot of work into our troubled shabti box, including investigating and analyzing the varnish (more on the analysis in an upcoming post), doing some pretty cool imaging, and consolidating all flaking and unstable varnish and paint with methylcellulose. After consolidation of the surfaces, the box does not look much different than it did when I started the treatment (and this is a good thing). As a reminder, here is an image of the front of the box before treatment:

shabti box frontAt this point, I could call the treatment done, or take it a step further, by filling in some of the losses of the painted surface, which appear bright white since those losses expose the gesso below. After consulting with Dr. Jen Wegner in the Egyptian Section and with Lynn Grant, the head of our department, I decided to fill in some of the larger losses which really make it difficult to appreciate the object and “read” the designs. I have even heard some visitors refer to the box as “that badly damaged piece of wood”, and that is not what we want people to be thinking when they eventually see this on display. While I know I can never return the box to its original condition, I can reduce the appearance of some of the damage. But how to fill the losses on such a fragile surface, in a way that will be reversible/retreatable?

After some hemming and hawing and some failed tests, I ultimately decided to fill the losses by first placing a small piece of Japanese tissue paper into the loss, then applying a tinted fill mixture over the paper. I did this by doing the following:

1. I took a quick snapshot of the surface I was about to work on. I then downloaded the image and copied it into a Word document. Using the scale in Word, I was able to resize the photograph in order to print it approximately true to size, and then I printed the image in black and white. This took no more than 5 minutes.

2. I placed a piece of Mylar over the B&W print-out and traced the losses I wanted to fill with a black marker.

3. After trimming the Mylar around one of the tracings, I taped it to a piece of Japanese tissue paper with a small piece of blue tape.

5. I then applied a fill mixture over the Japanese tissue paper. The fill mixture is made of 5% methylcellulose, glass microballoons, and powdered pigment.

This may sound tedious, but the whole process works very smoothly and relatively quickly. It also minimizes the amount of time I need to spend touching the object and therefore minimizes damage that might be caused by touching the very fragile surface.

I’m not finished, but so far I’m pretty happy with how the front of the box is looking:

It’s subtle, but to see the difference that filling makes, here are views before and after, side-by-side:

The only problem is, I feel like I’ve opened a can of worms. There are so many losses and I am not going to fill them all, but as soon as the larger losses are filled, I start seeing all of the small ones! I think it’s looking better though and I will get some feedback from my colleagues before proceeding further.

 

Completing the treatment of Tawahibre’s coffin

Things have been pretty busy around here lately, and I almost forgot to post some updates about several projects. One project in particular is the treatment of Tawahibre’s coffin. We have been working on this 2-part painted wooden coffin in the lab for the last year, and we recently completed its treatment.

As you may remember, when the coffin first came up here, it was covered with a thick layer of dust and grime, the paint was badly flaking in areas, several large pieces of painted gesso were pulling away from the wood support, and there were large cracks throughout.

After cleaning the surface with a brush and vacuum, followed by cosmetic sponges, I consolidated the paint with a methyl cellulose solution, filled in cracks and gaps using Japanese tissue paper and a mixture of methyl cellulose bulked with cellulose powder and glass microballoons, and then toned the fills with acrylic paint. This work is explained in further detail in previous posts, which you can find by clicking on the links included in blue above.

Based on a discussion with our Egyptian section curators, I also made some aesthetic fills to mask some large losses, including 2 losses on the wig. We chose not to fill the losses on the nose and chin because filling these losses would require too much guess-work as to the original contours of these features.

I carried out similar work on the base of the coffin, and now both are complete:

As you can see, we chose not to fill many of the losses, focusing instead on stabilization.

This work will enable future exhibition of the coffin, and just as importantly, it will make further study of the coffin possible. All along there have been some discrepancies between the name that has always been associated with the coffin (Tawahibre, a woman’s name) and a previous translation in 1946 of the hieroglyphic text on the coffin (which identified the name of a male court official, the son of J-se(t)-N-Ese). There has also been some confusion about the remains once housed in the coffin, which were previously identified as male, but in a 1975 autopsy the remains were confirmed as belonging to a female in her mid-30s. A bit confusing, but hopefully we’re now one step closer to getting this all straightened out!
