Opening: Beyond the Edge of the Map

Let us unroll the world map a medieval European might have imagined. At the center lies the Mediterranean, and around it spread the known lands. And at the edge of the map, it is said, a phrase was often written — "Here be dragons." The unknown sea was an object of fear. No one could be certain what lay beyond that endlessly stretching water.

Yet at the close of the fifteenth century, a few Europeans began to steer their ships beyond that fearful edge. They pressed out into the vast unknown sea, and as a result one of the most dramatic events in human history unfolded. The scattered continents were woven, for the first time, into a single web. This is the period we call the Age of Exploration.

This adventure showed humanity two great faces at once. One face is curiosity and courage, the advance of technology, the connection of the world. The other face is conquest and exploitation, the slave trade, and the diseases that swept through native peoples. This essay does not look at only one face. For only by gazing at the light and the dark together does the true shape of this colossal transition reveal itself.

1. Why They Set to Sea: Spices, Gold, and Faith

"A Handful of Pepper, Worth Its Weight in Gold"

One of the most powerful motives for the great voyages was, surprisingly, on the dinner table. It was spices. Pepper, cloves, nutmeg, and cinnamon were traded at enormous prices in the Europe of that time. They lifted the flavor of food, aided its preservation, and were at times symbols of wealth and status.

The trouble was that most of these spices grew in far-off Southeast Asia and India. That route had to pass through the hands of many middlemen, and at each step the price soared. Europeans began to think: "What if we could go straight to the source of the spices by sea, without passing through the middlemen?" This desire became the first driving force of the great voyages.

Why Were Spices So Costly?

To understand the price of spices, we must follow the road they traveled before they reached the table. Cloves and nutmeg, for example, are said to have grown only on a few small islands in the eastern part of today's Indonesia. For these spices to reach the markets of Europe, they had to make a journey of a length that is hard to imagine.

Harvested at the source, the spices first passed into the hands of a local merchant, then were sold to traders crossing the Indian Ocean. They were carried on to the great markets of Arabia and the Middle East, handed there to the merchants of the Mediterranean, and at last entered the cities of Europe. At every stage of this long chain, freight costs, the burden of risk, and the profit of the middlemen were added on. Between the first price at the source and the price on the European table, an enormous gap opened up.

On top of this, spices were small in bulk and did not spoil easily, which made them well suited to transport over long distances, while demand for them held steady. Because the value packed into a single small sack was so great, spices came to be regarded as a kind of "portable wealth," beyond mere seasoning. Who held the chokepoints of this trade was, in effect, the question that decided who reaped immense profit.

Table: The Road the Spices Traveled

StageSettingWhat Happened
1. SourceIslands and coasts of Southeast Asia and IndiaSpices harvested and passed to a local merchant
2. Indian OceanThe Arabian Sea and Indian Ocean routesTraders carry them by ship toward the Middle East
3. Middleman marketGreat cities of the Middle East and ArabiaPrice rises again as goods pass to Mediterranean merchants
4. MediterraneanPort cities such as those of ItalyBrought into Europe and distributed inland
5. The tableAcross EuropeTraded at many times the price at the source

Take in this table at a glance, and you understand at once why Europeans clung so fiercely to the sea routes. If only they could skip whole middle stages of the chain, all that profit would fall into their own hands.

Gold and Faith

It was not spices alone. A craving for gold, and a passion to spread faith, also pushed the voyages forward. The Europe of that time held a religious sense of mission to spread Christianity into a wider world, and at the same time sought new sources of wealth.

Historians often group these three together as the motives for the voyages.

These three strands of motive entwined together and pushed Europe's ships out into the unknown sea.

Why Europe, and Within It, Why Portugal and Spain?

There is a fascinating question. In terms of seafaring skill, other civilizations of the age were no less capable. So why did the great exploration of the Atlantic begin in earnest first in the small countries at Europe's western edge, Portugal and Spain?

Several reasons are pointed to. These countries lay geographically against the Atlantic, and being in a relatively disadvantaged position on the overland routes east and in Mediterranean trade, they desperately wanted a new path. Their crowns, too, actively sponsored the voyages, and the seafaring arts and knowledge of other civilizations flowed into Europe, ripening the technology. It was the result of many conditions gathering in a single place.

Portugal's West African Coast, Descended Step by Step

We tend to picture the Age of Exploration as beginning with Columbus in 1492, but in truth its foundation had been laid down, layer by layer, in Portugal for decades before that. Portugal did not open the road to India in a single stroke; it felt its way along the sea route, descending southward step by step along the western coast of Africa.

At first they went only as far as nearby places. Then, one year and another, the southernmost point the ships reached crept a little farther each time. The farthest point one voyage reached became the starting point of the next, and in this way the unknown coastline was filled in on the map, one segment at a time. Until at last the road opened that rounded the southern end of the African continent and entered the Indian Ocean, this gradual exploration was the fruit of decades of dogged accumulation.

What mattered in this process was not a single heroic leap but a system in which failures and information piled up. Where, and in what wind and current, a ship had found itself; which coasts were dangerous and which held water and food — all of this was recorded on each voyage and passed on to the next.

Patronage and the Legend of the "School of Navigation"

In this period, Portugal is said to have had a member of royalty who actively sponsored seafaring. The figure commonly called the "Navigator," Prince Henry, is the representative example. He did not himself board a ship and sail out into the far seas, but he is spoken of as a man who sponsored many voyages of exploration and who gathered and encouraged knowledge of navigation and mapmaking.

In later ages, a romantic story was added — that he gathered scholars, navigators, and mapmakers in one place and ran a kind of "school of navigation." Historians today are cautious about whether such a "school," with buildings and classrooms, truly existed in that form. One thing, however, is clear. The steady patronage of the crown, and the effort to gather knowledge and pass it to the next generation, were what upheld Portugal's gradual exploration.

It is worth remembering that the Age of Exploration was not opened by individual courage alone. Behind it stood patrons who treated seafaring as a business and supplied funds and people, and the unseen hands that recorded experience and handed it down.

2. The Technology of Sailing the Unknown

To board a ship and press for months toward unseen land was a challenge that might be likened to going out into space today. What made it possible was the combination of several technologies.

The Tools That Carried the Voyages

Tool / TechniqueRole
CompassGives direction regardless of charts, weather, or stars
Astrolabe and quadrantGauge latitude from the height of the stars and sun
The caravelA nimble sailing ship that handled headwinds relatively well
Charts and navigational knowledgeRecording and sharing accumulated experience
CannonA means of defense and intimidation on distant voyages

The compass in particular was decisive, for it kept sailors from losing their direction even on overcast days when the sun and stars could not be seen. And the nimble ship called the caravel had an excellent ability to sail against the wind, which made it well suited to long ocean voyages.

The Struggle with Fear

Yet the greatest challenge may not have been technology but the mind. They had to spend weeks and months on a vast open sea without a single point of land in sight. Food and water dwindled away, and diseases such as scurvy tormented the crews. A storm could swallow a ship at any moment. The courage to endure this fear of the unknown and press onward — that was another driving force that opened the Age of Exploration.

What Was a Day Aboard Ship Like?

Unlike the romance of the adventure tales we picture today, life aboard ship was in fact harsh, cramped, and precarious. Dozens of people had to live for months pressed together aboard a single small sailing ship. Sleeping quarters were poor, the deck was always swaying, and everything was soaked through with seawater and damp.

The greatest problem was food. Fresh provisions ran out within a few days, and after that the crew had to survive on preserved foods such as hard biscuit and salted meat. In time even these crawled with insects and grew moldy. Clean water, too, was scarce. Such a diet brought on malnutrition, and its representative result was scurvy, in which the gums broke down and strength drained away.

Discipline, too, was severe. When many people are shut for a long time in a narrow space, quarrels and unease are bound to accumulate, and the captain had to control the ship through strict discipline. The pay was meager, and many of the sailors were men who, out of poverty, had nowhere else to go and so had boarded the ship. Behind the phrase "a great voyage" was packed, dense and complete, a daily life this shabby and this grueling.

When we call up this reality, it strikes us anew how reckless and how desperate a challenge it was to set out into the unknown sea. It was a heroic resolve, but it was at the same time the last choice of poor people seeking to survive.

3. One Common Misconception: "Did People Back Then Believe the Earth Was Flat?"

When we speak of the Age of Exploration, one misconception comes up often. It is the story that when Columbus set out to sail west, those around him tried to stop him, saying that he would "fall off the edge of the earth." It is often painted as though everyone in that age believed the earth to be a flat disc. But this is, in large part, an exaggeration manufactured by later ages.

In fact, the idea that the earth is a round sphere was already known to the scholars of ancient Greece, and among educated people in medieval Europe it was close to widely accepted common sense. Clues had been known from early on — the observation that the tip of a ship's mast remains visible to the last as the ship disappears beyond the horizon, or the round shadow the earth casts upon the moon during a lunar eclipse.

So the real debate in Columbus's time was not "is the earth round or flat?" The heart of the debate was "how large is the earth?" In other words, opinions split over how wide the sea would be if one sailed west to reach Asia. Many scholars judged that the distance was too great for the ships of the time to endure with their food and water — and in fact, this skeptical side was the more accurate one in its calculation of the distance.

To correct this misconception is not mere nitpicking. It is bound up with an attitude — refusing to look down on the people of the past as ignorant beings, and seeing the knowledge and the limits they had as they truly were. When we study history, we often fall into the temptation to portray those of the past as more foolish than ourselves. To guard against that temptation is also part of a balanced gaze.

4. Three Great Voyages

Columbus: The Belief That Sailing West Reaches the East

In 1492, Christopher Columbus crossed the Atlantic westward with the sponsorship of the Spanish crown. His plan was bold. Rather than going the long way round to the east, he would sail straight west and reach Asia (India and China).

But his calculation held a great error. He reckoned the size of the earth to be far smaller than it actually was. Had the American continents not lain in his path, his fleet might have run out of food before reaching Asia and met its end upon the sea. Yet on that road lay two enormous continents no one had foreseen. Columbus believed to the end that he had arrived at the edge of Asia, but the place he actually reached was the Americas.

Some of the greatest discoveries were made upon the greatest of mistakes.

Vasco da Gama: The Road to the Real India

While Columbus wandered in the west, Portugal's Vasco da Gama took a different road. He rounded the southern tip of the African continent and, in 1498, at last reached the real India. With this, the sea route from Europe to India was opened, and the landscape of the spice trade was overturned. A direct passage to the wealth of the East had been opened.

The significance of this route was great. Recall the long, long chain of middlemen that the spices had traveled through before. Once the sea route opened, European merchants could skip whole stages of that chain and draw closer to the source. The power of the middleman forces that had long held the chokepoints of trade weakened, and the flow of wealth began to be rewoven. The road one ship opened shook the whole board of the world economy.

Yet this "direct route" was not a blessing for everyone. Along the new sea route, Europe's trading posts and armed force reached out into every corner of the Indian Ocean, and in that process the existing order was shaken and conflicts arose. The opening of a road has always meant, for some, an opportunity, and for others, a threat.

Magellan's Fleet: Around the World

The most dramatic voyage was the expedition led by Ferdinand Magellan in 1519. His fleet attempted an unprecedented route — crossing the Atlantic, rounding the southern tip of South America, and traversing the vast Pacific. Magellan himself lost his life in the Philippines during the voyage, but one of his ships at last returned to Spain in 1522. It was the first voyage in human history to circle the globe.

The Pacific, a Vast Silence

The harshest stretch of this voyage was the crossing of the Pacific. After Magellan's party had barely slipped out of the narrow, treacherous strait at the southern tip of South America, they are said to have felt relief at the calm sea that spread before their eyes. The name "Pacific" — the peaceful sea — is said to have come from that impression.

But that peacefulness soon turned into a merciless ordeal. They had no idea how vast this sea was. It took months to reach the next land, and in that time food and water ran out. According to the records handed down, the sailors, driven by starvation, survived by eating leather, sawdust, and even the rats that swarmed the ship, and many fell to scurvy. The empty horizon, stretching on without end, was a terror in itself.

Grasping the Size of the Earth with the Body

This agonizing crossing branded one important fact into humanity — that the earth, and the sea upon it, was far larger than people had vaguely supposed. The "round earth" they had known in the head became, through this voyage, the "vast earth" they had lived through in the body.

This voyage carried meaning beyond mere adventure. It proved with the body that the earth is round and that all the seas are joined into one. The world was no longer scattered fragments but a single, connected sphere. And those who returned alive discovered one strange fact. Though they had kept a ship's log all along, the date was off by a single day. To circle the earth from east to west is, in effect, to "gain" a day — a new realization in which time and space were entangled together.

5. The Columbian Exchange: The World's Table Is Transformed

One of the greatest consequences born of the Age of Exploration is what the historian Alfred Crosby named the Columbian Exchange. This refers to the large-scale movement of crops, livestock, people, and diseases between the New World (the Americas) and the Old World (Europe, Asia, and Africa).

A Revolution at the Table

A great many of the foods we eat without a second thought today are, it turns out, products of this exchange. Imagine for a moment: what if this exchange had never happened?

In this way, the Columbian Exchange fundamentally transformed the tables and the agriculture of people across the whole world. American crops such as maize and the potato are credited by some with contributing greatly to the population growth of the Old World. Within the food we eat each day, the trace of a great connection that began five hundred years ago is deeply inscribed.

Table: The Columbian Exchange, From Where to Where

Old World → AmericasAmericas → Old World
Wheat, rice, sugarcanePotato, maize, tomato
Horse, cattle, pig, chickenChili pepper, cacao, tobacco
Coffee, banana, onionSquash, peanut, vanilla
(Tragically) diseases such as smallpoxCommon bean, pineapple, sweet potato

How the Potato and Maize Changed the Fate of Populations

If we see the Columbian Exchange merely as an event in which "the table grew more varied," we lose its weight. The true shock of this exchange showed itself in the scale of populations.

Maize and the potato were crops of outstanding nutrition and productivity, able to feed more people on a smaller plot of land than many crops of the Old World. The potato in particular grew well even on cool, barren ground where grain did not thrive. Thanks to this, land that had long been hard to farm was turned into land that yielded food.

Historians hold that such crops, carried over from the Americas, contributed in no small measure to the population growth of Europe and Asia. More food meant more people, and more people in turn became the foundation of cities and industry, and of yet another historical change. The crops of one continent lifted the population curve of another.

Of course, this story has its shadows as well. A region that came to lean too heavily on one or two crops could suffer a terrible famine when those crops were swept away by disease. That the very dependence which brought plenty became the seed of vulnerability reminds us again that the Columbian Exchange was not a simple blessing.

That It Was a Two-Way Flow

There is one more point to mark down. The Columbian Exchange was not a one-way street in which "the Old World gave something to the Americas." Crops, livestock, and diseases all passed in both directions. The Americas gave the world's table the potato and maize, the tomato and the chili and cacao, while the Old World carried wheat and horses, cattle and sugarcane to the Americas.

Yet the "price" of this exchange was by no means paid out fairly. For while the Old World gained crops, the Americas received not only crops but deadly diseases along with them. Two flows that crossed the same bridge left, on one side, plenty, and on the other, catastrophe.

6. The Silver of the Americas and the First World Economy

Another great consequence born of the Age of Exploration lay outside the table — in the flow of money. Of all that Europeans found in the Americas, what shook the world most was not gold but silver.

The American continents held abundant silver mines, and under the colonial system an immense quantity of silver was dug out. This silver flowed to Europe, but it did not stop there. A considerable portion was loaded again onto ships and carried across to Asia. For at that time, in Asia — and especially in East Asia, with its enormous markets — the demand for silver was great. European merchants used the silver of the Americas to buy the silks, porcelain, and spices of Asia.

As a result, the silver dug from the Americas flowed through Europe and into the markets of Asia, and a circulation of money that quite literally circled the globe was created for the first time. Metal dug from the mines of one continent moved the silk of another, and that trade in turn affected the economy of yet another. Scattered local economies began to be woven into one great net.

Many historians find the earliest form of what we today take for granted as the "world economy" in this flow of silver. Of course, this early world economy, too, held its light and its shadow together. The labor in the mines that dug out the silver was brutal, and that glittering trade rolled forward upon the suffering of countless people.

7. The Deep Shadow: Conquest, Disease, the Slave Trade

Here we must honestly face the dark face of the Age of Exploration. This was an age of curiosity and connection, but it was at the same time an age of conquest and suffering.

The Invisible Conqueror, Disease

The greatest tragedy that befell the native peoples of the Americas was not the sword or the gun, but invisible pathogens. Against the diseases the Europeans brought — smallpox, measles, and the like — the native peoples of the Americas had almost no immunity. As a result, native populations are thought to have collapsed catastrophically in many regions. By some estimates, over the century or two after contact, an enormous portion of the native population vanished.

This was not a deliberate massacre but, for the most part, an unintended biological catastrophe — yet its result was horrific. The very mechanism that brought plenty to the table through the Columbian Exchange — the connection of two worlds — at the same time nearly broke the population of one of those worlds. Few examples show more starkly that light and shadow grew from the same root.

Why Was Disease So Brutal in Only One Direction?

Here a natural question arises. Why did disease travel mainly from the Old World to the Americas, and so one-sidedly at that? Scholars offer several explanations.

Among those often cited is that the people of the Old World had long lived close to many domesticated animals and had been exposed to a range of infectious diseases. Within that long exposure, the groups that survived came to possess a certain resistance. The native peoples of the Americas, by contrast, had had almost no opportunity to come into contact with such diseases, and so they had not yet acquired the shield of immunity.

So when the two worlds first met, a pathogen one side had long endured and grown used to became, for the other side, a deadly and unfamiliar enemy met for the first time. This was a tragedy that arose not because one side was superior, but because the histories the two worlds had walked were different. That it was a matter not of superiority but of chance and history is a point that must be kept in mind when we try to understand this tragedy.

Conquest and Colonies

The various societies of the Americas, weakened by disease, fell to the European conquerors. That great empires submitted to relatively small numbers of invaders owed to superior weapons and horses, to internal division, and above all to disease working together. Afterward, the vast lands of the Americas became colonies of the European powers, and immense wealth, gold and silver among it, flowed to Europe.

The Tragedy of the Atlantic Slave Trade

The deepest darkness of the Age of Exploration is the Atlantic slave trade. As the plantations and mines of the Americas came to need labor, over the course of centuries countless Africans were forcibly seized, carried across the Atlantic, and sold into slavery. This inhuman trade gave rise to suffering beyond reckoning, and its scars remain deeply embedded in many societies to this day.

To speak of the Age of Exploration while turning away from this fact would be only half the history. Behind the light of the world's connection, a shadow this vast was cast.

Forced Labor and Lives Broken Down

The slave trade was not the whole of the darkness. The native peoples of the conquered lands, too, were often subjected to brutal forced labor in the mines and on the plantations. Behind the glittering trade in silver we saw earlier stood countless nameless people who toiled, and fell, under conditions hard to endure.

Seen this way, the plenty of the Age of Exploration was by no means won for free. The sugar and spices that rose to the European table, the silver and silk that circled the markets, paid as their price the forced labor and the stolen lives of distant places. This is why, when we speak of the "prosperity" of any age, it is important to ask together upon whose shoulders that prosperity rested.

8. How Should We Judge It? A Balanced Gaze

How should we look upon the Age of Exploration? This remains a heated topic of debate even today. A period once celebrated as a heroic "age of discovery and adventure" is increasingly being rewritten from the perspective of those who were conquered.

Setting Two Perspectives Side by Side

These two perspectives may look like a contradiction, but in fact both are part of the truth. A mature understanding of history means not erasing one side but facing both at once. To acknowledge the courage of the great voyages while not turning away from the suffering they left behind. To savor the rich exchange of food and culture while remembering upon whose sacrifice that exchange was made.

To look at history honestly is to embrace together the parts we are proud of and the parts we are ashamed of.

This essay does not force a single position as the correct answer. But please remember that whoever sees only the light, or only the dark, understands the Age of Exploration by half.

By What Measure Do We Judge an Age?

There is another problem that makes a balanced judgment difficult — the question of whether it is truly fair to measure the deeds of the past by the measure of today. On this point, too, people's thinking divides.

On one side, some say that the people of that age lived within the values of that age, and so to condemn them one-sidedly by today's standards is not just. On the other side, others reply that the cruelty of the slave trade and forced labor was something the people who suffered in that age clearly felt, and that we must not lightly wave that suffering away with the words "it was the times."

This essay does not declare that either side is wholly right in this debate. But it holds that both positions have something worth taking to heart. The effort to understand the past, and the honesty to look suffering in the face — these two do not exclude each other. We can weigh the limits of the people of the past while not forgetting the suffering they left behind. The maturity with which we face history may be precisely the strength to bear that very tension.

Looking Again at the Word "Discovery"

When we speak of a balanced gaze, one thing we cannot leave out is the very words we use. We commonly say that Columbus "discovered" the Americas. Yet if we look closely at this expression for a moment, there is something strange about it.

For thousands of years already, countless people had been living on the American continents. Societies that built great cities, made precise calendars and writing systems, and cultivated rich cultures were there. To them, that land was not an unknown land to be "discovered" but the homeland they had lived in all along.

The word "discovery" quietly takes the European gaze as the standard of the world. The moment we call the instant a European came to know of their existence a "discovery," the long history of the people already living there is erased, as if it had never been. This is why many people today try to use words such as "contact" or "encounter" instead of "discovery" — words that do not lean toward the perspective of one side.

This is not merely a matter of quibbling over wording. Which word we choose reveals through whose eyes we are seeing history. The same event becomes an entirely different story when we call it "discovery," when we call it "invasion," and when we call it "encounter." A word is already a perspective.

Through the Eyes of an Imagined Sailor — A Night on Some Voyage

Here let us pause and look at the sea through the eyes of one person who lived in that age. What follows is not a real figure but an imagined scene, drawn by picturing a common sailor of that time.

They call me Manuel. I grew up on the poor docks of Lisbon, and I boarded this ship for want of a single piece of bread. For months I have not seen land. My mouth is raw, my gums bleed, and the salt biscuit crawls with worms. At night I lie on the deck and gaze up at unfamiliar stars. Their positions are not those of the stars I saw at home. I cannot read, but this much I know — that we are sailing toward the edge of the world.

The captain says that at the end of this sea lies a land of gold and spices. Whether that is true, I do not know. Perhaps we are merely sailing off to starve and die. Even so, I cannot turn back. For waiting in the home I would return to is only a worse hunger. On this night, where only the sound of the waves stretches on without end, I am no more than a man who rows, not even knowing what it is he is rowing toward.

Without ordinary sailors like this imagined Manuel, no great voyage would have advanced a single step. Behind the great names of the history books were the fear and the hunger and the courage of countless people who left not even their names. And on the land those ships reached were yet more countless people, who either welcomed them or had their lives taken from them. History is always made of the innumerable gazes of such nameless people.

9. Toward Today's World — The Light and Shadow of Connection

The "single connected world" the Age of Exploration opened is, in fact, the distant ancestor of the age of globalization we live in today. Upon the roads laid down by the ships that set out chasing spices more than five hundred years ago, our airplanes and container ships and internet data now travel back and forth.

Connection has certainly brought plenty. We eat fruit from the far side of the globe, use goods made far away, and enjoy the cultures of other continents as an everyday matter. Knowledge and technology, too, cross borders and spread swiftly. All of this stands on an extension of the connection that the Age of Exploration first threw open.

Table: Then and Now, Connections Alike Yet Different

Set the connection of the Age of Exploration alongside the connection of today, and we see at a glance that, while the essence is alike, how greatly the scale and the speed have changed.

Point of ComparisonThe Age of ExplorationToday's World
Means of connectionSailing ships and sea routesAirplanes, container ships, the internet
Time to travelFrom months to yearsFrom hours to seconds
Mainly carriedSpices, silver, crops, peopleGoods, capital, information, people
LightNew wealth and the exchange of goodsPlenty, the rapid spread of knowledge
ShadowConquest, disease, the slave tradeInequality, environmental strain, the rapid spread of crisis

What this table tells us is clear. The technology of connection has advanced beyond comparison, but the structure in which "light and shadow come together" is not much different now from what it was five hundred years ago. Though the tools have changed, the essence of the problem we must solve is strikingly alike.

Yet there is another truth the Age of Exploration taught us — that a shadow always follows connection. Just as, in that age, the connection of two worlds carried disease along with plenty, the globalization of today, too, holds its light and shadow together. For some, connection is an opportunity; for others, it becomes the loss of a job or exposure to greater inequality. The way a disease in one region spreads across the world in an instant is something we have lived through even recently.

This is why to study the Age of Exploration is not merely to peer into the past. It is to face a question that is urgent for us now as well — "what is connection, and how shall we handle its light and its shadow?" That question, which the old navigators never managed to ask, we their descendants must ask more honestly.

Connection Does Not Stop

There is one more point worth thinking over. It is the fact that the connection the Age of Exploration threw open, once begun, never turned back. Once the two worlds were joined and crops and people and ideas began to move between them, the world could no longer go back to being scattered as it had been before.

This "irreversibility" holds true today as well. We may criticize certain aspects of globalization, but we cannot make connection itself into something that never was. If so, the question that remains is not "to connect or not to connect," but "how shall we tend an already connected world to be more just and more wise?" The Age of Exploration stands at the starting point of that ancient question.

10. The Picture of the World Is Drawn Anew

Another deep change the Age of Exploration left behind was the very way people "drew the world in their minds." On the maps before the voyages, only the known lands were drawn, and beyond them the space was filled with imagination and fear. As we saw, at the edges were written phrases of the sort "Here be dragons."

But each time a voyage ended, the empty space was filled in, little by little, with real coastline. The realm of vague fear turned into a realm of measured and recorded knowledge. This was not merely a matter of a single map; it meant that humanity had begun, for the first time, to grasp the planet it lived on as a "whole."

Of course, the world map drawn this way, too, held the perspective of one side. Who placed what at the center, and which lands were called by what names, was steeped in the gaze of the one who drew it. A map is a record of objective fact, and at the same time a mirror that shows how the civilization that drew it wished to see the world.

Even so, what is clear is that through this period humanity came, for the first time, to share a picture of a "single round world." The scattered local maps were merged into one globe, and only upon it did the word "world" come to hold the meaning we use today.

11. Key Terms

Let us gather in one place the important concepts that have appeared in this essay.

TermMeaning
Age of ExplorationThe period, from the late fifteenth century, in which Europe's ships pressed out into unknown seas and connected the continents
Columbian ExchangeThe large-scale movement of crops, livestock, people, and diseases between the New World and the Old World
CaravelA nimble sailing ship that handled headwinds relatively well
ScurvyA disease, arising from a lack of fresh food, that tormented sailors on distant voyages
Atlantic slave tradeThe inhuman trade in which countless Africans were forcibly seized and bought and sold as slaves
ContactA word used, instead of "discovery," from a perspective that tries not to lean toward one side

12. In Closing: We Are the Heirs of That Voyage

The Age of Exploration has ended, but the world it made is still beside us. The food we eat each day, the loanwords within the languages we speak, the trade and movement that cross continents — at the root of all this lies that voyage of more than five hundred years ago.

In a sense, we are the heirs of that voyage. We enjoy the plenty of the world they connected, and at the same time we have inherited the history of the wounds they left. To study the Age of Exploration is not merely to enjoy a tale of past adventure, but to understand upon what light and what dark the connected world we live in today was built.

The age of writing "Here be dragons" at the edge of the map has passed. Now almost no unknown continent remains upon the earth. Yet before humanity there still spread other unknown seas — space, the future, and ourselves. When we set out for those seas, we must carry with us not only the courage of the old voyages but also the lessons drawn from their shadow.

The greatest lesson the Age of Exploration left us may, perhaps, be this — that great deeds and shameful ones are often tangled together within a single event, and only when we have the courage to look upon both together can we at last learn from history. To remember only the light is to fall into conceit, and to dig up only the dark is to fall into cynicism. The honesty to embrace both at once — that is the most precious legacy the voyage of five hundred years ago hands to us today.

May this essay become a small occasion for calling to mind a wider and deeper landscape beyond the familiar adventure tale. This connected world we live in was built together upon someone's courage and someone's tears. From the act of remembering them both, our own voyage toward a better connection will at last begin.

Things to Ponder

  1. From whose perspective is the word "discovery" written? To the people already living there, what was it?
  2. Like the Columbian Exchange, can you call to mind other historical cases in which an unintended connection gave rise to enormous consequences?
  3. When great achievement and deep suffering are mingled together within a single event, how should we remember and teach it?
  4. Why did misconceptions arise, such as the idea that the people of the past believed the earth was flat? How can we guard against the temptation to portray the people of the past as more foolish than ourselves?
  5. Just as the potato and maize changed the population of one continent from another, what are some cases today in which a small change in one region shakes the whole world?
  6. Upon whose shoulders does the plenty that today's globalization enjoys rest? How can we, now, apply the lessons of the Age of Exploration?
