Many of you may be wondering about Nespekashuti, our New Kingdom mummy whose remains are quite a jumble under his wrappings. As you can imagine, Nespekashuti is presenting some interesting conservation challenges for us. So far I have focused on surface cleaning and trying to understand the extent to which his linen wrappings are damaged. I decided that before I can deal with stabilizing Nespekashuti any further (and making the decisions necessary to do this), I need to address the damage to his coffin.
Nespekashuti’s coffin is quite interesting. I’ve only been able to examine the lower half (which he is contained in) so far. It is made of several pieces of wood doweled together, followed by coating with gesso in areas, then the exterior surface is entirely covered with a single layer of linen, which was coated with gesso and painted, and then finally varnished, likely with pistacia resin. Overall, the painted surface of the coffin is in great condition. But there are some structural concerns, including breaks in the wood, separation and movement between different pieces of wood, and separation of the linen, gesso, and paint from the wood substrate.
I’m starting out my treatment by readhering areas where the linen is lifting away from the wood and plaster below. To repair these areas, I’m using a tried-and-true combination of methyl cellulose, methyl cellulose bulked with glass microballoons, and Japanese tissue paper.
This is just the beginning! Once I finish working on the areas I can access, I’ll have to move the coffin to a support that allows me to access the underside/back, so that I can better evaluate and treat those areas as well.
