The Age of the "Magic Mud" — Before Black Liquid Moved the World

Until little more than a century ago, oil was not the star of the world. It decided no wars and held no nation’s fate in its hands. And yet humanity’s relationship with this “black liquid” is far older than you might think. Our story begins in the land between two great rivers.

The black mud that welled up from the ground

In the Middle East — Mesopotamia above all (around present-day Iraq) — you didn’t need to dig to find oil. Some of the oil deep underground seeped up through cracks in the rock, and as it met the air its lighter components evaporated away. What remained was a black, sticky mass: natural asphalt, also known as bitumen.

To ancient people, this was not something to burn. The idea of setting it alight for heat or light was not yet the main point. What caught their attention first was its stickiness and its ability to repel water. It dried hard, sealing every gap. There was no better “natural cement,” no better “natural waterproofing,” anywhere in their world.

It is, when you think about it, a curious thing. The gasoline, kerosene, and plastics we picture when we hear the word “oil” can only be extracted by heating crude and refining it through complex processes. Ancient people had no such technology. All they could lay hands on was what nature had already concentrated at the surface — a kind of “half-finished product made by the Earth.” So it was only natural that the first uses leaned toward waterproofing and bonding, which required no processing at all.

Floating arks, raising temples

The uses of this black mud were astonishingly varied.

First, waterproofing. Coat the surface of a boat made of bundled reeds with bitumen, and water would not soak in; it could stay afloat far longer. It was an essential technique for transport and fishing on rivers and marshes. The Book of Genesis famously records that the great ark was coated inside and out with pitch to keep out the water, and tells of people using bitumen to bind the bricks when they tried to build a tower to the heavens. Whatever the details of myth, behind them lives a real memory of everyday life: of “warding off water and joining things together with black mud.”

Next, building. When stacking sun-dried bricks, pouring bitumen into the joints locked the bricks together and kept out the rain. In this land of little rainy season, sun-dried brick was a cheap, quick building material — but it had a fatal weakness: it was poor against water. Bitumen filled that weakness perfectly, as if by providence. At the feet of Mesopotamia’s great ziggurats and city walls, this black adhesive was indeed at work. A city of earth and mud, held up by another kind of mud — you might put it that way.

And in an unexpected place: medicine. Salves rubbed on wounds and skin, painkillers, even filling gaps in masonry to keep out pests. The black mud slipped into every corner of daily life. Surface oil was, in some regions, used as fuel for torches and simple lamps as well — but even so, it never grew beyond a “material that made local life a little more convenient.” Not as a force that moved the world, but as a tool of daily living, ancient oil sat quietly at people’s side.

Mummies and the origin of the word “mummy”

The strangest legacy of all lies in its connection to mummies.

In ancient Egypt, resin, salt, and a black bitumen-like substance are thought to have been used to keep bodies from decaying. Over time, as the surface of the corpses turned black and dry, people came to see them as “things hardened with bitumen.”

Here the words begin to shift. In Persia, black, asphalt-like substances were called mūmiyā, a word derived from the local term for “wax.” In time this word came to denote the blackened, dried bodies of ancient Egypt themselves, and crossing into Europe it became the English word mummy. In other words, “mummy” — traced back to its root — was the name of an oil-derived substance.

Not yet a “weapon,” not yet a “fuel”

Looking back this way, ancient oil bears almost no resemblance to the thing we imagine today.

There were no oil fields, no pipelines, no tankers. No haggling over prices, no wars fought to seize it. People gathered only what seeped from the ground, and used it to waterproof, to bind, sometimes to rub on the body — it was nothing more than a handy material within reach. Humanity did not yet know of the vast reserves of oil sleeping deep underground.

And yet one thing is certain. The Middle East lived “alongside oil” from the very dawn of civilization. The region that touched oil earliest and wove it into daily life was the very one that would, one day, come to hold the fate of the world.

Why did so much oil gather in this one region? It is thought to trace back tens of millions of years, to a time when this land lay beneath a warm, life-filled shallow sea. The remains of countless plankton settled onto the seafloor and, over vast stretches of time, were pressed and heated deep in the earth until they were transformed into oil. As the land shifted and sea became dry ground, some of it seeped up to the surface. The black mud that ancient people gathered was the final gift left behind by life of the distant past. Without knowing its meaning, they were touching the memory of the Earth itself.

For this sleeping black mud to become “the lifeblood that rules the world,” one vast historical force was needed: an age when chimneys belched black smoke and machines began to work hundreds of times harder than any human — the Industrial Revolution. Soon humanity would bore deep into the earth and, in the wilds of Persia, send a single jet of history-changing liquid roaring into the sky. The story moves to 1908.
