When we look at a modern map, it is easy to assume that we are seeing the world as it really is. North is usually at the top, borders appear as clean lines, and places have fixed names. But none of those choices is quite as natural or permanent as it seems.
My reading of the historical evidence suggests this is a dangerous assumption. Historical maps were not simply imperfect attempts to reproduce geography. They were constructed arguments. Cartographic theorists have long recognized that a map is never a purely scientific document. It is a highly curated text embedded with cultural assumptions, theological hierarchies, and raw political power.
Every line drawn on parchment required a choice. The most revealing aspect of historical cartography is often what theorists term cartographic silences: the deliberate decision to omit indigenous territories, downplay rival nations, or ignore complex topographies in favor of clean, easily administered geometric grids. Maps are not simply transparent copies of reality. Their purpose, scale, projection, labels, omissions, and intended audience shape what they communicate. By analyzing the borders, names, monsters, and projections of the past, we can begin to see maps not as passive pictures of the world, but as active instruments used to shape it.
Section One
Maps as Pictures of What People Believed
To understand how drastically the purpose of mapping has shifted, we have to abandon the idea that maps were always meant for wayfinding. If you judge medieval European cartography by the standards of modern GPS navigation, it appears hopelessly inaccurate. But this relies on a fundamental misunderstanding of its underlying epistemology. These maps were not designed to help a merchant sail from London to Venice. They were designed to chart the soul’s relationship to God and history.
Created around 1300, the Hereford Mappa Mundi was not designed for navigation. It served as a visual encyclopedia of the Christian worldview, placing Jerusalem at the exact center of the earth.

Created by Richard of Haldingham around the year 1300, the Hereford Mappa Mundi is one of the most spectacular surviving examples of a medieval world map. Structurally, it is based on the traditional T-O map design. In this framework, the world is depicted as a circle (the “O”) divided by a T-shaped cross representing major bodies of water: the Mediterranean Sea, the Nile, and the Don. These waters separated the known continents of Asia, Europe, and Africa.
The most crucial detail of the Hereford map is its focal point. It places Jerusalem at the exact center of the world. This is not a geographical miscalculation, it is a deliberate theological conviction that the Holy City was the spiritual and physical fulcrum of human existence. Furthermore, the map is oriented with East at the top. This orientation was chosen because East represented the location of the Garden of Eden and the origin of divine light.
When we look at the Hereford Mappa Mundi today, we are not looking at a failed attempt to map topography. We are looking at a highly successful attempt to map biblical time, classical mythology, and spiritual hierarchy onto a single plane. It is an encyclopedia of faith.
Section Two
The Unknown, Monsters, and the Limits of Knowledge
A recurring motif in the popular understanding of old maps is the presence of sea monsters and mythical creatures. It is tempting to dismiss these illustrations as mere superstitious decorations drawn by terrified cartographers afraid of the open ocean. The historical evidence suggests a far more pragmatic and complex reality.
Olaus Magnus’s 1539 Carta Marina features a vast array of sea monsters. While fantastical to modern eyes, these creatures represented the era’s genuine attempts to categorize perilous marine biology.

SignificanceMarine Biology Integration
Printed in Venice in 1539, the Carta Marina is a monumental wall map of Scandinavia that provides one of the most exhaustive visual catalogs of marine mythology ever produced. It depicts the Norwegian Sea teeming with giant crustaceans pulling sailors from ships, massive sea serpents wrapping around vessels, and giant polypi (octopuses) snatching men straight from the decks.
I think it is a mistake to view every sea monster as a literal scientific classification, but it is equally wrong to view them as pure fantasy. As cartographic scholars have noted, these creatures were often derived from exaggerated encounters with actual marine biology. The walrus, for example, is described on the map as a marine beast the size of an elephant that sleeps hanging from rocks by its teeth. The giant squid was a genuine biological reality interpreted through the lens of folklore and survival panic.
In the context of the sixteenth century, these monsters served highly practical purposes. They warned sailors of genuine maritime hazards, such as dangerous currents or aggressive fauna. They acted as encyclopedic records of natural history during an era obsessed with categorizing the natural world. Finally, they solved the aesthetic problem of horror vacui (the fear of empty spaces), filling the cartographic silences of the open ocean with symbols of nature’s untamed power.
Beyond maritime mythology, cartographers sometimes featured completely invented landmasses that persisted for centuries. The “Mountains of Kong,” first introduced into the cartography of West Africa by English geographer James Rennell in 1798, is a perfect example. Despite having no basis in physical reality, this massive, fictitious mountain range was copied by subsequent mapmakers and appeared on commercial and military maps for nearly a century.
The phantom mountains were only removed in the late nineteenth century after French explorer Louis Gustave Binger physically traversed the region and proved they did not exist. This phenomenon underscores the danger of treating printed maps as unimpeachable scientific truths. A map can dictate human behavior, trade routes, and military strategies based on entirely fabricated geographic assertions.
Section Three
When Maps Became Instruments of Empire
The transition from the Middle Ages to the Renaissance saw maps evolve into highly classified instruments of statecraft, diplomacy, and imperial expansion. To possess an accurate map was to possess a distinct logistical advantage over rival empires.
The Cantino Planisphere (1502) was a highly classified Portuguese state secret, containing the latest discoveries of the New World, until it was stolen and smuggled to Italy by a spy.

SignificanceEarly Brazilian Depiction
The Cantino Planisphere of 1502 perfectly illustrates the commodification and weaponization of geographic knowledge. The map represented the cutting edge of the Portuguese Padrão Real, the master map of maritime discoveries that was tightly guarded by the Portuguese crown. It was secretly commissioned and smuggled from Portugal to the Duke of Ferrara by an agent named Alberto Cantino.
The map is historically vital because it blends the traditional rhumb lines of medieval portolan charts with the new science of astronomical navigation. It contains some of the earliest visual depictions of the Brazilian coast, reached by Pedro Álvares Cabral just two years prior in 1500. By delineating the geopolitical division of the globe established by the Treaty of Tordesillas, the map illustrates how cartography was used to lay visual and legal claim to foreign lands and resources long before physical military control was fully established.
Martin Waldseemüller’s 1507 Universalis Cosmographia is famous for being the earliest known map to use the name “America” for the newly represented lands.

Waldseemüller’s 1507 Map
Similarly, Martin Waldseemüller’s monumental 1507 Universalis Cosmographia demonstrates the extraordinary power of the mapmaker to alter human geography permanently. Created in Saint-Dié, France, this twelve-sheet woodcut map recognized the landmasses of the Western Hemisphere as a distinct, separate continent surrounded by a distinct ocean.
Relying on the travel accounts of Amerigo Vespucci rather than Christopher Columbus, Waldseemüller’s 1507 map is famous for being the earliest known map to use the name “America” for the newly represented lands. He later expressed doubts about Vespucci’s primacy, even retracting the name “America” and labeling the continent Terra Incognita in his 1513 atlas.
However, the 1507 map had already circulated widely due to the advent of the printing press. The power of the printed map had superseded the intent of its creator, cementing the name into the global consciousness. (If you are interested in how single documents or artifacts manage to survive the centuries to tell these stories, I recommend exploring how historical artifacts survive against the odds, as only one single copy of this 1507 map is known to exist today, discovered in a German castle in 1901).
Section Four
When Maps Helped Define Borders and Political Reality
As the modern nation-state emerged in the eighteenth and nineteenth centuries, cartography became an important tool in administering and solidifying political borders. We often assume that maps simply record changing borders as empires rise and fall. The reality is that maps played an active role in defining them. A geopolitical entity’s existence in the international consciousness was often reinforced when it was delineated on a map with a firm, unmistakable border.
In Europe, the shifting borders of Prussia, the Austro-Hungarian Empire, and the Ottoman Empire were continuously documented and legitimized through cartography. Following the collapse of these empires, cartographers were deployed to carve up the remnants, creating new nation-states. The borders drawn on these maps often forced disparate ethnic and linguistic groups into unified geopolitical entities. (This tension is a recurring factor in understanding how history and borders are frequently edited or erased by those in power.)
This causative power of maps is most glaring in the context of colonial cartography. During the Berlin Conference of 1884–1885, European powers partitioned the African continent using maps of territories they had barely traversed. Cartographers drew geometric lines across the continent, dividing indigenous nations and disrupting ancient trade routes. It would be an oversimplification to say that Europe drew random straight lines and created every modern conflict single-handedly. However, the map undeniably preceded the territory. The lines drawn in European map rooms dictated the physical reality on the ground, serving as instruments of colonial administration, resource extraction, and territorial power.
Section Five
Maps as Political Propaganda
By the late nineteenth and early twentieth centuries, the state’s monopoly on mapmaking expanded into the realm of overt public propaganda. Because human beings naturally trust the apparent objectivity of a map, cartography became a highly effective tool for persuasion.
Fred W. Rose’s 1899 “Serio-Comic” map of Europe abandons geographic accuracy entirely, instead using the medium of the map as a piece of political propaganda to depict the Russian Empire as a predatory octopus.

Persuasive Cartography
Fred W. Rose’s “Angling in Troubled Waters”
This dynamic is vividly illustrated by the rise of “Serio-Comic” maps of Europe. Fred W. Rose’s 1899 map, Angling in Troubled Waters, utilizes anthropomorphic and theriomorphic designs to convey complex geopolitical tensions to the general public. One of the best-known motifs from these maps is the depiction of the Russian Empire as a massive, grasping octopus, its tentacles reaching aggressively into Eastern Europe, Scandinavia, the Middle East, and Asia.
These maps dispensed entirely with the pretense of geographic accuracy. Instead, they utilized the spatial relationships of the continent to dehumanize adversaries, simplify complex diplomatic crises, and generate domestic support for aggressive military postures. They prove how geographic form can be transformed into a visceral political argument, persuading emotionally rather than informing mathematically.
Section Six
The Problem of the “Objective” Map
Even when a map attempts to be purely mathematical, it runs into a fundamental physical problem: the Earth is three-dimensional, and paper is flat. Any flat projection introduces some form of distortion. You cannot flatten a sphere without stretching or tearing it.
The most famous example is the Mercator projection, introduced by Gerardus Mercator in 1569. It is vital to accurately explain why Mercator became so dominant. It should not be described simply as “a propaganda map.” Mercator created his projection to solve a specific, highly technical navigational problem. His map allowed sailors to plot a course using straight lines (rhumb lines) that maintained a constant compass bearing. In an era of global maritime expansion, this mathematical breakthrough was revolutionary.
However, the mathematical trade-off of the Mercator projection is that it severely distorts size as latitude increases toward the poles. It dramatically enlarges the apparent size of Northern Hemisphere landmasses, making Greenland look roughly the size of Africa (when in reality, Africa is about 14 times larger). While not designed as propaganda, this visual scale distortion heavily influenced modern perception. Its distortion of relative area nevertheless influenced how generations of readers visually perceived the world’s geography, particularly when the projection was used in general-purpose world maps.
Section Seven
How to Read a Historical Map Like a Historian
If we accept that maps are constructed representations rather than infallible objective records, how should an ordinary reader approach them? The key is to interrogate the document. When you look at a historical map, you should ask a specific set of forensic questions:
The Cartographic Toolkit
Who made it, and who paid for it? The patron often dictates the perspective.
When was it created? Contextualize the map within the scientific and political knowledge available at the time.
What is centered? The focal point (like Jerusalem in the Hereford map) reveals the creator’s cultural priorities.
What is emphasized or exaggerated? Enlarged borders or highlighted resources indicate economic or political interests.
What is missing? Cartographic silences—the omission of indigenous populations, unmapped terrain, or rival claims—are often deliberate choices rather than simple ignorance.
How are places named? Renaming a territory (like Waldseemüller naming America) is an act of claiming it.
What purpose did the map serve? Was it for maritime navigation, theological instruction, or public propaganda?
“Maps are not simply transparent copies of reality. Their purpose, scale, projection, labels, omissions, and intended audience shape what they communicate.”
Conclusion
More Than Just Territory
The history of cartography is not a simple, linear march from primitive ignorance to GPS precision. It is the history of human ambition. A historical map is not simply a picture of territory. It is evidence of how people understood, organized, claimed, imagined, and sometimes manipulated space.
The next time you examine a historical map, look past the charming inaccuracies and the mythological creatures. Look for the invisible infrastructure of power, the silent borders of empire, and the profound beliefs of the people who held the pen. The most fascinating secrets a map reveals are rarely about the geography of the earth; they are about the psychology of the mapmaker.

Frequently Asked Questions
Addressing common curiosities about the history of cartography.
Why were historical maps often inaccurate?
Many historical maps, especially from the medieval period, were never intended to be used for geographic navigation. Maps like the Hereford Mappa Mundi were theological encyclopedias designed to show spiritual hierarchy, biblical history, and classical mythology rather than strict topographical reality.
Why did old maps contain sea monsters?
Sea monsters were not purely mythological superstitions. They often represented the era’s best hypotheses of marine biology, derived from exaggerated encounters with real animals like walruses or giant squid. They also served the practical purpose of warning sailors about dangerous ocean currents while filling empty spaces on the parchment.
What can historical maps tell us about politics?
Maps often reflect the interests of those who commissioned and created them. By examining what is centered, what borders are drawn, and what territories are deliberately omitted (cartographic silences), historians can see how empires laid legal and visual claims to land long before they physically controlled it.
How did maps help empires expand?
Maps were important instruments of statecraft. Access to detailed maritime charts gave naval powers logistical advantages, while colonial mapping helped European governments survey, administer, and claim territories. Maps alone did not create colonial rule, but they were important tools in making territorial control legible and enforceable.
Why is the 1507 Waldseemüller map important?
Martin Waldseemüller’s 1507 map is famous for being the earliest known map to use the name “America” for the newly represented lands. Its importance also lies in how quickly printed cartography helped spread new ideas about the geography of the Western Hemisphere.
Are historical maps reliable sources?
Historical maps can be valuable evidence for understanding how their makers and patrons understood territory, power, geography, and political space. However, they are inherently unreliable if treated as purely objective, scientific reflections of physical geography.
