Can Ships Fall Off the Edge of the World? Uncovering the Myths of Old Seafaring 🌍

My name is Davide Ramponi, I’m 20 years old and currently training as a shipping agent in Hamburg. On my blog, I take you with me on my journey into the fascinating world of shipping. I share my knowledge, my experiences, and my progress on the way to becoming an expert in the field of Sale and Purchase – the trade with ships.

If you’ve ever seen a medieval map, you’ll know they can look more like fantasy novels than navigational tools—filled with dragons, whirlpools, and ominous warnings like “Here be monsters.” One of the most persistent myths from the age of sail was the fear that ships might sail too far—and fall off the edge of the world. 🌊

It sounds absurd to us today. But centuries ago, this fear was very real—or at least, very real in the minds of many people on land. So where did the idea of a flat Earth come from? Did early sailors truly believe they could sail off the edge? And what other strange beliefs shaped early seafaring?

In this post, we’ll journey back to a time before GPS and globe models, uncover the myths and fears that once guided (and misled) maritime exploration, and explore why these stories still captivate our imagination today.

The Origins of the Flat Earth Myth 🗺️

Let’s start with the big one: Did people in the Middle Ages really believe the Earth was flat? The answer is both simpler—and more complex—than you might expect.

📜 Where the Idea Came From

The notion of a flat Earth goes back thousands of years. Ancient cultures—including Mesopotamians, Egyptians, and early Greeks—depicted the world as a flat disc surrounded by water or sky.

But already by the 5th century BCE, Greek philosophers like Pythagoras and Plato proposed a spherical Earth. Aristotle even offered observational evidence:

• The round shadow Earth casts on the moon during lunar eclipses

• The way ships disappear hull-first over the horizon

• The changing position of stars based on latitude

So, by the time of Eratosthenes (3rd century BCE)—who even calculated Earth’s circumference with remarkable accuracy—the educated consensus was clear: the Earth is round. 🌍

🏰 What About the Middle Ages?

Contrary to popular belief, most scholars in medieval Europe didn’t believe in a flat Earth either. Writers like Thomas Aquinas and Dante referenced a spherical Earth in their works.

So where does the myth that “people thought Columbus would fall off the edge” come from?

Blame it on 19th-century romanticism. Writers and historians of that era exaggerated medieval ignorance to make the Age of Enlightenment seem more heroic. In reality, most sailors knew they wouldn’t fall off the edge—but that didn’t mean they weren’t afraid of what lay beyond the known world.

The Horizon of Fear: How Flat Earth Ideas Influenced Seafaring 🚢

While navigators may have understood Earth’s shape in theory, knowledge was uneven. Among common folk and even sailors, fear of the unknown remained strong.

🔍 Knowledge vs. Belief

Early explorers often lacked detailed maps. Voyages into uncharted territory were filled with uncertainties:

• How far does the sea go?

• Are there monsters beyond the horizon?

• Will we ever return?

To the untrained mind, the ocean was endless—and if there were no clear borders, who’s to say there wasn’t a deadly edge?

Maps like the Mappa Mundi or T-O maps of medieval Europe depicted the world symbolically, not geographically. That symbolism often left plenty of room for fear—and fantasy.

Legendary Explorers Who Proved the World Wrong 🧭

So, who helped dispel the myths and replace fear with fact? Let’s meet a few bold mariners who turned the edges of maps into stepping stones.

🌍 Ferdinand Magellan (1480–1521)

The Portuguese explorer led the first circumnavigation of the globe (even though he didn’t survive the full trip). His fleet sailed west from Spain, around South America, across the vast Pacific, and returned via the Indian Ocean.

🔑 Key lesson: You can sail around the world—there’s no edge to fall off.

⛵ Christopher Columbus (1451–1506)

Despite the legend, Columbus didn’t believe the Earth was flat. His concern was more about how far Asia extendedwestward—not whether he’d fall off the planet.

🔑 Key lesson: Even controversial figures like Columbus operated with a round-Earth worldview.

🧭 James Cook (1728–1779)

Captain Cook’s Pacific voyages helped map entire coastlines and debunk myths about a massive southern continent or mythical islands.

🔑 Key lesson: Careful observation and mapping could replace myth with measurable reality.

Monsters, Myths, and Maritime Madness 🐉🌊

The fear of falling off the edge was just one of many myths that haunted early seafarers. Some of the most colorful were... well, monstrous.

🐙 The Kraken

A giant squid-like creature from Norse mythology, said to pull ships into the deep. Inspired by real sightings of giant squid (which do exist!).

🐉 Sea Serpents

Appearing in various cultures—from Norse Jörmungandr to Chinese dragons—these serpents symbolized chaos and the fear of the unknown.

🌪️ Whirlpools and Waterfalls

Some believed great oceans had giant maelstroms or waterfalls at their edge that could suck a ship under.

🧜‍♀️ Sirens and Mermaids

Beautiful yet deadly, these creatures were said to lure sailors with their songs—possibly inspired by manatees, long voyages, and sleep deprivation.

These legends weren’t just bedtime stories. Sailors wrote about them in logbooks, and cartographers illustrated them in the margins of sea charts. It was their way of making sense of a world they didn’t yet fully understand.

Why These Myths Still Fascinate Us Today ✨

Even in our modern, GPS-enabled world, the idea of undiscovered places still excites us. Myths may no longer control where we sail, but they still shape how we dream.

🌌 Storytelling at Sea

• Films like Pirates of the Caribbean and Master and Commander play with old legends

• Books like Moby Dick or The Odyssey build on seafaring fears

• Video games like Sea of Thieves and Assassin’s Creed IV reimagine mythical sea creatures and cursed waters

🧠 The Psychological Pull

We’re wired to fear what we don’t understand—and to create stories to explain it. Even if we know the world is round and fully mapped, a part of us loves the idea that somewhere out there, beyond the horizon, there could be something more.

What These Stories Teach Us ⚓

There’s more to these myths than fantasy. They reflect the very real challenges and fears of early sailors:

• Navigating without reliable maps or instruments

• Facing violent storms and unknown currents

• Being isolated from land and supplies for weeks or months

• Encountering new lands, peoples, and animals that seemed otherworldly

In short, they were trying to write a story about survival—and the sea became both their setting and their metaphor.

Even today, working in shipping means facing uncertainty, risk, and trust in human skill and technology. The myths remind us of the courage that came before.

Conclusion: There Was Never an Edge—Just Opportunity 🌊🧭

So, can ships fall off the edge of the world? Of course not. But for early sailors, that idea was a stand-in for the deeper fear: the unknown.

📌 The flat Earth myth was more cultural than scientific
