The paint made of people

There is a brown that sits, in tint, exactly between burnt umber and raw umber. It glazes beautifully. It is transparent in a way earth pigments usually are not, which makes it very good for shadows and for the warm half-dark under skin. Painters loved it for about two hundred years. It was called mummy brown, and the name was not a metaphor.

It was made of mummies. Egyptian ones, mostly — also Guanche mummies from the Canary Islands, also cats — ground up and mixed with white pitch and myrrh. An artists’ supply shop in Paris called À la momie was selling paint, varnish and powdered mummy by 1712. A London Compendium of Colours in 1797 recorded that the finest brown glaze used by Benjamin West, then president of the Royal Academy, “is the flesh of mummy, the most fleshy are the best parts.”

The part I keep turning over is that this was not a secret. It was in the shop name. It was in the catalogue, with buying advice.

Nobody had to be deceived, because the deception had already happened upstream, centuries earlier, in medicine. Ground mummy — mummia — had been sold in Europe as a drug for everything from toothache to dysentery long before anyone thought to paint with it. By the time it reached a colourman’s shelf it arrived as an established commodity with a supply chain and a price, and a thing that already has a price is very hard to see as a person. The pigment did not require a new moral decision. It inherited one.

Demand outran supply, as it does. Genuine Egyptian mummies ran short, and the gaps were filled with the bodies of the recently dead — enslaved people, executed criminals. After the French Revolution the hearts of French kings were removed from the abbey of Saint-Denis and made into paint. That sentence is the whole logic of the trade in one line: once a body is a material, the difference between a pharaoh and a king and a person nobody will miss is a question of availability.

The end of it is not a reform. It is one man in a garden.

In 1881 the painter Edward Burne-Jones was having lunch with Lawrence Alma-Tadema, who mentioned having seen a mummy at his colourman’s workshop shortly before it was ground up. Burne-Jones had argued that the name was only borrowed, a way of describing a shade. His wife Georgiana wrote down what happened when he understood it was literal: he went upstairs, fetched his one tube of mummy brown, and took it out to the garden to give it “a decent burial there and then.” The children came out and helped. They marked the spot.

I find that funeral almost unbearably good, and also completely useless, and I think both facts matter. A tube of paint is not a person and burying it returns nothing to anyone. But it is what was available to him at the moment of finding out, and he did it immediately, with his children watching, rather than finishing the tube and resolving to buy differently next time. The gesture was the entire content of the apology. It was also the only honest response available to someone who had already used the stuff.

The pigment did not die of shame. It died of logistics and quality control. It faded. It cracked when used alone. It contained ammonia and particles of fat, which attacked whatever colours you mixed it with — Church’s Chemistry of Paints and Painting warned that “little reliance” should be placed on it. By 1915 a London colourman said he could meet twenty years of orders from a single mummy. The last distributor, C. Roberson of London, ran out of mummies in the early 1960s; Time reported it in 1964. Not a ban, not a scandal, not a decision. They ran out of mummies. It ended as a stock problem.

You can still buy mummy brown today. It is kaolin, quartz, goethite and haematite — clay and iron oxide, the iron minerals doing the colouring, and the name doing nothing but marketing. Meanwhile the real thing is presumably still sitting in museums, inside paintings people queue to see, mostly unidentified: testing for it destroys a sample, so almost nobody tests. The Last Sleep of Arthur in Avalon, Drolling’s Interior of a Kitchen, possibly Delacroix’s Liberty Leading the People — the attributions rest largely on the fact that the colour looks right.

Which leaves the thing where I think it honestly sits. Not with a villain. With a shop, a shade that worked, a supply chain nobody looked up the length of, and a couple of centuries of people buying the best available brown.
