Here is a detailed explanation of the bizarre and macabre history of "Mummy Brown," a pigment literally made from the ground-up remains of ancient Egyptian mummies.

The Origins of a Macabre Medium

Mummy Brown, known in French as Brun de Momie and scientifically cataloged as Caput Mortuum (Latin for "dead head"), was a rich bituminous pigment that sat on the palettes of European artists from the 16th century well into the early 20th century.

Its origins lie in a misunderstanding of medicine. In the Middle Ages, a substance called mummia—a pitch or bitumen found in the Near East—was prized for its supposed medicinal properties. Through mistranslation and opportunism, European apothecaries began believing that the bitumen used to embalm Egyptian mummies possessed the same healing powers. This led to a trade in grinding up mummies for medicine. Eventually, artists realized that this same ground-up powder, when mixed with oil or varnish, created a unique and versatile paint.

The Pigment: Why Artists Loved It

Despite its gruesome origin, Mummy Brown was genuinely prized by artists for its technical qualities. It was not a gimmick; it was a workhorse color, particularly among the Pre-Raphaelites in Britain and French Romantics.

• The Color: It was a rich, warm brown, somewhere between burnt umber and raw sienna. It possessed a transparency that made it excellent for glazing (layering thin coats of paint) and capturing shadows.
• The Texture: Because it contained bitumen and human fat, the paint had a creamy, buttery consistency that was satisfying to apply.
• Flesh Tones: Ironically, the ground remains of the dead were considered perfect for painting the skin of the living. It added a realistic warmth to portraits.

Notable users of the pigment allegedly included Eugène Delacroix, William Beechey, and members of the Pre-Raphaelite Brotherhood like Edward Burne-Jones.

The Supply Chain: Robbing the Dead

The Victorian demand for this pigment (and for mummies as curiosities) fueled a rampant and destructive trade in Egypt.

1. Excavation: Local Egyptians and European adventurers would scour necropolises for mummified remains. Both human and feline mummies (Egyptians mummified cats in the millions) were harvested.
2. Transport: The bodies were shipped to Europe by the boatload. Upon arrival in ports like London or Liverpool, they were sold to "colourmen"—the manufacturers who supplied paint to artists.
3. Processing: In the backrooms of art supply shops, the mummies were crushed. The bones, bandages, and desiccated flesh were ground into a fine powder. This powder was then mixed with drying oils (like poppy or walnut oil) and amber varnish to create the tube paint.

The quality of the paint varied. "Premium" Mummy Brown was said to come from bodies that had been embalmed with the highest quality bitumen and resins, usually indicating a person of high status in ancient Egypt.

The Victorian Turning Point

While the pigment had been used for centuries, it was the Victorian era that saw both its peak popularity and its sudden, scandalized demise.

For a long time, many artists were vaguely aware of the name "Mummy Brown" but treated it as a fanciful trade name, much like "Dragon's Blood" (a red resin) or "Bone Black." They did not necessarily believe they were painting with actual human corpses.

The Epiphany of Edward Burne-Jones: The most famous anecdote regarding the end of Mummy Brown involves the Pre-Raphaelite painter Edward Burne-Jones. In 1881, he was visited by his niece, Rudyard Kipling's future wife, and Lawrence Alma-Tadema, another prominent artist.

Alma-Tadema casually mentioned that the paint was made from actual mummies. Burne-Jones was horrified. He refused to believe it, insisting the name was metaphorical. When Alma-Tadema assured him it was literal, Burne-Jones famously rushed to his studio, grabbed his tube of Mummy Brown, and insisted on giving it a "decent burial." He marched into his garden and buried the tube of paint in the earth, marking the spot.

The Decline and Disappearance

The trade did not stop solely because of moral outrage, though that played a part. It ended due to a combination of three factors:

1. Changing Ethics: As the 20th century approached, respect for archaeological finds grew. The idea of grinding up humans for art became increasingly repugnant to the Victorian and Edwardian public.
2. Technical Flaws: Despite its beauty, Mummy Brown was chemically unstable. Over time, the bitumen caused the paint to crack and wrinkle (a defect known as "alligatoring"). Furthermore, it was a "fugitive" pigment, meaning it faded significantly when exposed to sunlight, ruining the artworks it was used to create.
3. Supply Issues: Simply put, they ran out of mummies. In 1964, C. Roberson & Co., a famous London colourman, officially ran out of stock. The managing director reportedly told Time magazine, "We might have a few odd limbs lying around somewhere, but not enough to make any more paint."

Modern Equivalents

Today, you can still buy tubes labeled "Mummy Brown" or "Mummy," but they contain no human remains. Modern equivalents are synthetic mixtures of kaolin, quartz, goethite, and hematite, designed to mimic the hue of the original without the gruesome ingredients or the chemical instability.

The original paintings created with Mummy Brown hang in museums worldwide—silent, beautiful testaments to a time when the ancient dead were consumed to immortalize the modern living.
