The history of art is filled with strange and toxic materials—from deadly lead whites to arsenic-laced greens—but few pigments possess a backstory as genuinely morbid as Mummy Brown. Also known as Mommia or Caput Mortuum (though the latter term was also used for synthetic iron oxides), Mummy Brown was a rich, bituminous pigment that was exactly what its name suggested: paint manufactured from the pulverized remains of ancient Egyptian mummies.
Peaking in popularity during the 18th and 19th centuries, the story of Mummy Brown is a bizarre intersection of colonialism, grave-robbing, and fine art.
The Origins: From Medicine to the Canvas
The European consumption of mummies did not begin in the art studio, but in the apothecary. Beginning in the Middle Ages, Europeans mistakenly believed that mummia—a substance found in embalmed Egyptian bodies—possessed miraculous medicinal properties. For centuries, ground-up mummies were ingested to cure everything from stomach ulcers to epilepsy.
By the 16th and 17th centuries, as the medical fad began to wane, artists discovered that the powdered remains produced a uniquely beautiful pigment. The trade simply shifted from the pharmacy to the artist's colorman. Driven by the 19th-century craze of "Egyptomania"—a European fascination with all things ancient Egypt following Napoleon’s campaigns—thousands of mummies (both human and feline) were excavated, shipped to Europe, and sold to paint manufacturers.
The Manufacturing Process and Color
To make Mummy Brown, paint makers would grind up the entire mummy—flesh, bones, and the linen wrappings. This morbid powder was then mixed with white pitch, myrrh, and drying oils.
The resulting pigment was a rich, warm, transparent brown, falling somewhere between raw umber and burnt sienna.
Why Did 19th-Century Artists Love It?
Mummy Brown became a staple on the palettes of many prominent 19th-century painters, particularly among the British Pre-Raphaelite Brotherhood. It possessed specific qualities that made it highly desirable: * Transparency: It was perfect for "glazing," a technique where thin, transparent layers of paint are applied over dried layers to create deep, luminous shadows. * Flesh Tones: Ironically, artists found that the warm undertones of Mummy Brown were ideal for painting human skin and shading flesh. * Handling: It flowed beautifully off the brush and mixed well with other colors.
Famous painters known or suspected to have used Mummy Brown include Eugène Delacroix, Martin Drolling (who allegedly used the remains of French royalty interred at Saint-Denis), and Pre-Raphaelite artists like Lawrence Alma-Tadema and Edward Burne-Jones.
The Macabre Turning Point
Perhaps the most shocking aspect of Mummy Brown is that many 19th-century artists had no idea what they were using. Paint names are often fanciful—"Elephant’s Breath" or "Dragon’s Blood," for instance—and many painters assumed "Mummy Brown" was simply a clever marketing name for a shade of dirt.
The horror of realization is best captured in a famous anecdote from 1881. The painter Edward Burne-Jones was having lunch with fellow artist Lawrence Alma-Tadema and the poet Robert Browning. When Alma-Tadema casually mentioned that the paint was made from actual dead pharaohs, Burne-Jones was horrified. He immediately left the table, retrieved his tube of Mummy Brown from his studio, and gave it a respectful burial in his garden.
The Decline and Extinction of the Pigment
Mummy Brown eventually disappeared from artists' palettes for several reasons:
- A Shift in Ethics: As the science of archaeology developed in the late 19th and early 20th centuries, public attitudes toward Egyptian remains shifted from viewing them as commodities to respecting them as historical artifacts and human remains.
- Unpredictability: Because the pigment was literally made of organic matter of varying ages and embalming recipes, it was chemically unstable. It had a tendency to crack, dry poorly, and occasionally fade over time. Ammonia and fat from the bodies sometimes ruined the surrounding paint.
- They Ran Out of Mummies: The primary reason for the pigment's demise was supply chain failure. By the 20th century, the Egyptian government cracked down on the export of antiquities, and the readily available supply of mummies dried up.
The final nail in the coffin came in 1964. The managing director of C. Roberson & Co., a historic London colorman that had manufactured the paint for decades, famously told Time magazine: "We might have a few odd limbs lying around somewhere, but we don't have enough to make any more paint."
Legacy
Today, "Mummy Brown" can still be purchased in art supply stores, but modern iterations are created using a mixture of synthetic hematite, quartz, and kaolin—entirely free of human remains. However, the legacy of the original pigment lives on in museums around the world. When you look at the deep, warm shadows in a 19th-century masterpiece, there is a very real chance you are looking at the pulverized remains of an ancient Egyptian.
