The First Maps: Why We Started Drawing the World

The question hung in the air like morning mist over a valley—silent, uncertain, yet somehow pregnant with possibility. A traveler stood at the edge of unfamiliar territory, surrounded by landscapes that shifted with the seasons and the years. The rivers she knew had changed course. The mountains that once marked the horizon had been swallowed by forests that weren't there before. How, she must have wondered, does anyone find their way home when the world itself seems to shift beneath their feet?

We don't know the name of that traveler. We don't know if she was male or female, young or old, traveling alone or with companions. What we do know is that the question she faced—how to capture a world in motion, how to hold geography in your mind or your hands—was one that humans would wrestle with for tens of thousands of years. And the answers they devised, long before compasses or sextants, before paper or printing presses, would eventually evolve into the maps we use today.

This book is about that journey. It's about the scratched lines in caves and the etched circles in clay, about knotted strings and wooden frameworks, about the ancient and persistent human need to draw our world before we try to understand it. But it's also about something deeper: why do we feel this compulsion at all? What is it about the human mind that drives us to flatten three dimensions into two, to reduce the infinite complexity of terrain into simple symbols and lines?

The answers, as we'll discover, reveal as much about who we are as a species as they do about the landscapes we inhabit.

The Problem of Definition

Before we can explore the history of maps, we need to tackle an uncomfortable question: what exactly is a map?

This might seem like a straightforward matter. We know maps when we see them—the folded paper in our car's glove compartment, the colorful display on our phone, the creased tourist map of a foreign city. But once we start looking at the earliest attempts at cartography, the boundaries become surprisingly fuzzy.

Consider a curious object discovered in a cave in southern France in the 1990s. Known as the Marschallgjosen cave engraving, this piece of limestone, dating back approximately 14,000 years, features a series of lines carved into its surface. One prominent line curves across the stone, with smaller lines branching off at angles. The dominant interpretation among archaeologists is that this represents a river valley—possibly the nearby valley of the Ardèche—with its tributaries branching like the limbs of a skeletal figure.

But here's the problem: we can't be certain. That same pattern of lines could represent something else entirely. Perhaps it's not a landscape at all but a palm print, or a stylized animal, or simply an abstract design with no representational meaning whatsoever. The lines might have been carved for purely aesthetic reasons, or as part of a ritual, or by a child who found joy in scratching patterns into soft stone.

This ambiguity haunts the study of early cartography. When does a pattern of marks become a map? At what point does a random arrangement of lines transform into something deliberately intended to represent the world?

The philosopher and cartographer Mark Monmonier has suggested that a map is "a generalization of reality," a selective representation designed to communicate spatial information. But this definition raises as many questions as it answers. How selective? How abstracted? Must it be intentional, or can unconscious representations count?

For the purposes of this book, I'm going to propose a broader definition: a map is any physical or symbolic representation designed to convey information about spatial relationships—where things are, how they connect, what lies between them and what lies beyond. Under this definition, a child's crayon drawing of her house and the road leading to school qualifies as a map, as does the most sophisticated satellite imagery. What matters is not the medium or the skill involved but the intention to communicate something about space.

This inclusive approach has its costs. It means we must consider as potential maps objects that might have had entirely different purposes. It requires us to hold uncertainty as a constant companion, never quite sure whether we're seeing cartographic intention or something else entirely. But it also allows us to appreciate the full breadth of humanity's attempts to make sense of space, including the tentative, experimental, sometimes accidental first steps that would eventually crystallize into the maps we recognize today.

Babylon's View of the World

If there's one map that nearly all historians of cartography point to as the oldest recognizable example of the genre, it's the Babylonian Map of the World. This small clay tablet, measuring just 12.2 centimeters across, was discovered in the ancient city of Sippar in modern-day Iraq and dates to approximately 600 BCE. Today it resides in the British Museum, where it draws visitors who pause before its weathered surface, trying to make out the circles and crescents inscribed into clay that has survived more than two and a half millennia.

The map itself is rendered in a distinctive style. At its center lies a large circle, bisected by horizontal lines that represent the Euphrates River. This is Babylon, the great city at the heart of the Mesopotamian world. Surrounding this central circle are several other circles of varying sizes, connected to the center and to each other by lines and triangular shapes. The whole assembly is surrounded by a larger circular boundary, marked with eight triangular projections—what the Babylonians called "triangular regions" reaching into the ocean that encircled the world.

To modern eyes, this might seem a crude approximation of geographical reality. The world is flat, contained within a circle, with Babylon at its literal center. The ocean is a ring, and the landmasses are abstract shapes that don't correspond to any recognizable continent.

But such judgments miss the sophistication of what the Babylonian mapmakers were attempting. This was never meant to be a geographically accurate representation in the modern sense. Instead, it was a cosmological diagram, a visual expression of how the Babylonians understood their place in the universe.

The central circle represented not just Babylon but the sacred mountain of the gods, the axis around which the entire cosmos turned. The eight triangular regions might represent distant lands at the edges of the known world—Egypt to the southwest, Elam to the east, territories populated by mysterious peoples who existed at the margins of Babylonian experience. The ocean surrounding everything was the "Bitter River," the primordial waters from which all creation had emerged.

Even the inaccuracies tell us something important. The Euphrates appears as a horizontal line cutting across the map's center not because the Babylonians didn't know better—they had detailed knowledge of their river's meandering course—but because the horizontal axis had cosmological significance, representing the boundary between the heavens above and the underworld below.

Around the map's edges, we find inscriptions that further reveal the Babylonian worldview. The text, written in cuneiform script, provides brief descriptions of each region: "the land of the Suti and of the manners and customs of the land of the Suti." "The mountain of the Tigris." "The land of the Assyrians." Each description connects a geographical location with a people, a culture, a set of practices and beliefs.

This integration of geography and ethnography was characteristic of Babylonian thought. To know a place was to know its inhabitants; to map the world was to catalog its peoples. The Babylonian Map of the World was thus not just a spatial diagram but a comprehensive survey of the known universe and everything in it.
