Maps before GPS

Today, we rely on GPS to guide us almost anywhere. A few taps on a phone, and we know exactly how to reach our destination. But for thousands of years, humanity navigated the world using something far more fragile, artistic, and fascinating: hand-drawn maps.

Before satellites and smartphones, maps were more than tools for travel. They were expressions of imagination, power, trade, religion, and scientific knowledge. They helped empires expand, merchants explore, and explorers brave the unknown.

Maps didn’t just represent geography; they shaped history, defined borders, and even determined the fate of nations. They told the stories of where we were, where we wanted to go, and sometimes where we dared not venture.

The First Maps: Drawing the World from Memory

The earliest known maps weren’t printed—they were scratched into clay tablets, painted on animal skins, or etched into rock walls. Ancient Babylonians created city maps over 4,000 years ago. These early maps were less about scale and more about important landmarks—rivers, temples, and city centers.

In ancient Egypt and Mesopotamia, maps were closely tied to religion and the afterlife, with the Earth often depicted as a flat disk surrounded by water. These weren’t navigational maps in the modern sense, but they offered insight into how people understood their world.

For the Egyptians, the Nile River was central to their civilization, and maps were used to guide travelers to and from the river's resources. These maps also marked the locations of important tombs, royal estates, and sacred temples, which were critical to ancient Egyptian life.

In Mesopotamia, maps were often made on clay tablets that displayed towns, roads, and rivers but lacked precise scale. These maps were crucial for the kingdom's administration, helping to define territories and resources, and were likely used by trade caravans and military commanders.

Greek and Roman Mapping: A Step Toward Accuracy

The Greeks brought math into mapmaking. Around 500 BCE, Anaximander was one of the first to suggest the Earth was a floating sphere. His maps were based more on thought experiments and theoretical models than empirical evidence, but they represented a shift from mythological ideas to rational exploration.

Later, Eratosthenes used his knowledge of the Earth’s shadow during the solstice to calculate its circumference with remarkable accuracy—within just 1% of its true value. This was a huge leap forward in the quest to understand the world’s size and shape, and it laid the foundation for more accurate mapping in the centuries to come.

The Roman Empire took mapping to the next level—mainly for military control and logistics. Roman roads were carefully documented, and maps like the Tabula Peutingeriana showed routes across the empire, although not always to scale. The Roman mapmakers valued practical, usable maps, and their cartography served as crucial tools for trade and conquest.

Medieval Maps: Mixing Myth and Meaning

In medieval Europe, maps often reflected religious beliefs more than geography. A famous example is the T and O map, which placed Jerusalem at the center of the world and divided Earth into three continents—Asia, Europe, and Africa—based on biblical tradition. The "T" represented the rivers dividing these regions, and the "O" encircled the Earth, symbolizing water.

While medieval maps were based on religious ideas, Islamic scholars like Al-Idrisi took mapping to new levels of accuracy. His 12th-century maps presented geographical details of Europe, Africa, and Asia. Unlike the European T and O maps, which were symbolic and abstract, Al-Idrisi’s maps used astronomy and navigation principles to provide more realistic and accurate depictions of the known world.

Meanwhile, in China, cartographers were already developing more practical maps. Ancient Chinese maps from the Han Dynasty used grid systems and often included topographical features, such as mountains and rivers. These maps were used for both military purposes and to survey the vast Chinese Empire.

The Age of Exploration: Maps as Power

In the 15th and 16th centuries, European powers raced to explore the world. Accurate maps became crucial tools for navigation, conquest, and colonization. The Age of Exploration was marked by unprecedented maritime voyages, as explorers like Christopher Columbus, Ferdinand Magellan, and Vasco da Gama pushed the boundaries of the known world.

This period gave rise to:

• Portolan charts: Detailed sea maps used by sailors, showing coastlines, harbors, and wind directions. These charts helped explorers navigate vast oceans and become more confident in venturing farther from familiar shores.

• Mercator projection (1569): Created by Gerardus Mercator, this map made it easier for sailors to plot straight-line courses, even if it distorted the size of landmasses near the poles. The Mercator projection was revolutionary in that it helped create more navigable and practical charts, although it introduced distortions that still persist in modern maps.

Explorers relied heavily on these maps, even though many still showed sea monsters and mysterious lands on the edges of the known world. Maps during this time were not just practical tools—they were also powerful symbols of exploration, empire-building, and the desire to claim the unknown.

Maps, in the Age of Exploration, became symbols of empire and imperial dominance. The more you mapped, the more of the world you could claim.

The Art and Influence of Maps

Old maps weren’t just useful—they were works of art. They were often decorated with:

• Dragons and mythical creatures, marking the edges of the known world.

• Rich colors and intricate calligraphy, making them prized possessions of kings and scholars.

• Symbols of power, like royal coats of arms or religious imagery, which reflected the cultural and political dominance of the mapmaker's land.

These artistic elements were meant to serve more than just aesthetic purposes. They reflected the mapmaker’s view of the world and could influence how people thought about distant lands, unknown territories, and foreign cultures.

Maps also helped shape people's mental maps—how they understood distant places and territories. Inaccurate or distorted maps often fueled misconceptions, fears, and myths about the world. For example, the use of dragons and sea monsters in unexplored regions made the unknown seem more dangerous and unfamiliar.

Legacy and the Move to Modern Maps

By the 18th and 19th centuries, maps were becoming more scientific. Tools like the sextant, chronometer, and surveying instruments helped explorers chart coastlines and measure distances with precision. National governments invested in mapping their territories, creating modern atlases and topographical surveys.

The invention of photography and aerial surveying in the 19th century transformed cartography, giving rise to highly detailed and accurate maps that could be replicated for global distribution. By the early 20th century, satellite imagery and airborne radar would revolutionize mapping once again.

Still, even with better data, maps were always evolving. Boundaries shifted. Names changed. Unknown areas slowly became familiar.

Today, digital maps update instantly—but they owe their existence to thousands of years of trial, error, artistry, and imagination.

Final Thoughts: More Than Just Directions

Maps have always been more than just guides—they are windows into how people saw their world. They tell us what was known, what was feared, and what was dreamed.

From ancient Babylon to medieval monasteries to seafaring empires, every map holds a story. Before GPS, maps weren’t just tools—they were bold declarations: “We are here. And we are trying to understand.”

Maps helped shape exploration, trade, wars, and diplomacy. They bridged the gap between the known and the unknown, between imagination and reality.

While we may now have more advanced technology to help us navigate, we must remember that the art of mapping was one of the first ways humanity sought to make sense of the world. And for that, we still owe a lot to the maps of the past.
