Ancient Maps Nobody Can Make Sense Of

Added: 2026-05-12

[00:00:00]Somewhere in a French castle basement, a 4,000-year-old slab of stone sat ignored for over a century. It had been pulled out of a Bronze Age grave mound back in 1900, cataloged as a curiosity, and then just kind of forgotten about. It got shipped from one storage room to another, gathering dust. When researchers finally examined it with 3D scanning in 2021, they realized they were looking at the oldest known map of a territory in European history, and it matched the local landscape with more than 80% accuracy. People have been drawing maps for a really long time, longer than most people assume. The oldest surviving examples are also really quite strange. In some cases, they're pretty beautiful. In other cases, they are very controversial. So, today we're going to look at a Babylonian clay tablet no bigger than a paperback book that places monsters at the edge of the world. A medieval calf skin that tries to fit all of human history onto a single page. An Ottoman admiral's chart that conspiracy theorists swear shows Antarctica three centuries before anyone ever reached it.

[00:00:57]It didn't. and a Renaissance professor who drew up a continent he'd never seen, complete with rivers and mountain rages that he just invented from scratch. So, let's get into it. Today's video is brought to you by the good people over at Hule. Quick question, when was the last time you actually thought about how much fiber you're eating.

[00:01:16]Very rarely, without getting into details, only at certain times. And look, people think about protein. I think about protein. Definitely think about calories. Don't often think about fiber. And look, when you get busy, it's easy to skip meals. It's easy to eat just whatever's available. It's easy to just order something unhealthy from an app, isn't it? And then you're like, "Oh no, it's unhealthy and expensive. What have I done?" But that is where Hule comes in. I have been using their black edition powder. I think this is the chocolate one. Oh, this is cookies and cream. Oh, this is not open. My preference is the chocolate one. I love the cookies and cream is good. I also enjoy it, but chocolate is my jam. Uh, you mix it. It tastes less than a minute. Takes like 10 seconds. You just And you're done. And it includes all of the fiber you need, includes everything you need, which is fantastic. And it's also super cost- effective. It's way cheaper than most of the food options.

[00:02:04]Even if you go out to the supermarket to buy a sandwich, it's going to be cheaper. So instead of overthinking it, it just becomes a default, especially on busy days when you normally skip eating properly. Don't do that. Get yourself some Hu.

[00:02:21]Thank you to HU for sponsoring today's video. And now back to it.

[00:02:26]The Sam slab.

[00:02:29]For most of the history of archaeology, the oldest known maps in Europe were relatively recent things. Tomy's coordinates from the 2n century AD.

[00:02:36]Roman road itineraries. Greek parip parap par per paraploy. Greek paraploy describing coastlines. If you wanted to push the timeline back further, you would stark arguing over ambiguous cave paintings and rock art that might or might not represent landscapes. The assumption was straightforward enough.

[00:02:55]Sophisticated spatial mapping came from literate, complex societies. Bronze Age people in western France, nobody expected them to be drawing maps. That changed because of a rock that had been sitting in storage since 1900. The slab was originally excavated by an archaeologist named Paul Dartilier at Sambell in Flynnistier in Britany. I'm sorry French people. Dartellier was a prolific digger. He pulled out a stone, noted it had some interesting engravings, added it to his private collection, and moved on. After his death, the slab ended up in a shadow, and eventually made its way to a museum's basement. For 121 years, it sat in that basement. Then, in 2021, a team from INRAP, the French National Institute for Preventative Archaeological Research and Bournemouth University decided to take a bit of a closer look. Archaeologists Clemon Nicolola and Ivon Pelle subject.

[00:03:54]Someone told me once that if you want to pronounce French, you just say it with a really strong French accent and that's what I roll with. They subjected the slab to photoggramometry and high resolution 3D modeling. The thing is big, roughly 3.9 x 2.1 m or about 13 by7 ft. And what they found carved into its surface mattered. The lines and grooves on the slab match the topography of the Odet River Valley in western Britany with 80% accuracy. Rivers corresponded to known waterways. Repeated motives aligned with archaeological sites dated to the same period roughly 1900 to640 BC. Barrerows and settlements showed up on the stone and so did field systems.

[00:04:33]So did the creator have some sort of magical stone age GPS? Well, the tabloid certainly wanted that to be the case, but the scholar's interpretation is a bit more realistic and nuanced. The slab was almost certainly a prestige object, a political statement by a local elite who literally carved their territorial claim into stone. It was a bronze age power map before the Sambell slab's identification. The oldest confirmed territorial maps in Europe were millennia younger. The often cited Chattal Huyok wall painting from Turkey dating to around 6200 BC is increasingly disputed. Many archaeologists now interpret it as decorative or symbolic, not topographic. That leaves the Samlet slab as the current strongest candidate for the oldest European territorial map.

[00:05:21]A 4,000-year-old political land claim tucked away in a museum basement for more than a hundred years. Recognized only when somebody finally pointed a camera at it.

[00:05:31]The Babylonian world map.

[00:05:34]If Sallet slab is all business, a Bronze Age chieftain saying this land is mine, the next map on our list is something else entirely. It's a small paperbacksized clay tablet held in the British Museum under category number BM 92687.

[00:05:50]And now you know. It measures just 12 by 8 cm or about 5x3 in. And it dates to around 600 BC from the city of Sapar in Mesopotamia. That's in modernday Iraq.

[00:06:00]For a long time, scholars treated this object as a simple geographic curiosity.

[00:06:04]The Babylon at the center, the few cities marked around it, a circular ocean, some triangles at the edges. But recent digital ununiform translations from 2018 onward have revealed it to be more ambitious. So what's it actually show? Well, Babylon sits at the center.

[00:06:19]The Euphrates River flows through the middle of it. Surrounding city states, including Assyria, Alam, Haban, and others, are marked as small circles. A bitter river, their term for the ocean, encircles, it's a good way to describe saltwater, encircles the known world. And then beyond that ocean, seven triangular regions extend outward. These outer zones are described in the ununiform text as lands of impossible darkness, perpetual twilight, a place where the sun is not seen and realms populated by legendary heroes and monsters. Now, you might be thinking that this is purely mythological. Indeed, I was, dear writer. The tablet fuses real Mesopotamian political geography with Babylonian cosmology. The inner portion is a reasonable representation of the Mesopotamian world as its makers knew it. The Outer Islands line up with episodes from Babylonian epic literature, including journeys of mythic kings. It's both at once. The Mesopotamians were perfectly capable of practical mapmaking. They produced countless clay tablets with field surveys, canal plans, and city layouts, functional and accurate, but the world map is unique in its scope. It's the only surviving Babylonian attempt to depict the entire cosmos, not just a neighborhood or an irrigation district.

[00:07:32]What it reveals about their worldview is both familiar and also alien. Familiar because every culture puts itself at the center of the map. We still do this today. But alien because beyond the boundaries of the known, the Babylonians placed zones where the rules of nature stopped working. Darkness, monsters, the collapse of ordinary reality. This is a map of psychological space as much as physical space. The Babylonians put their capital at the center and monsters at the edge. 14 centuries later, medieval Christians would do the same thing, but on a much bigger piece of leather, the Turin Papyrus.

[00:08:09]Now, most ancient maps deal in myth, power, or cosmology. This next one, though, it's refreshingly blunt. It's about rocks. Fascinating. The Turin Papyrus map is a scroll about 2.8 m or 9 ft long, now held in the Museo Egazio in Turin in Italy. It's fragmentaryary, reassembled from multiple pieces, and it comes from roughly 1150 BC during the reign of Pharaoh Rammeses IV of the 20th dynasty. We even know who made it. The papyrus was prepared under the direction of a scribe named Ammoneti, son of Epipo. Ammoneti was a well-known figure from the village of De El Medina, the worker settlement that built the royal tombs in the Valley of the Kings.

[00:08:50]So, this wasn't anonymous bureaucratic Albert. We can put a name and a hometown to it. Well, that would be the Wadi Hamat region in the eastern desert of Egypt. A critical route between the Nile Valley and the Red Sea. And it uses color coding in a way that feels almost modern. Pink and red for hills of granite, dark brown for mountains and beckon stone, gray wacka, a type of sandstone prize for statues, and black dots for gold deposits. Quarries, settlements, a well, and a temple of Armon are all marked. There's nothing mystical here. There's no monsters or mythological kings. This was a working document for a stone quarrying expedition ordered by Rammeses V 6th. It told the vizier and overseers where to find specific stone types and precious metals and how to get there. You could hand this to a modern geologist and they would understand it immediately. It's the oldest surviving topographic and geological map in human history. By 1150 BC, Egyptians were encoding three-dimensional terrain onto a flat surface with functional accuracy and representing geological data systematically. They were making color-coded geological maps more than 3,000 years ago. But even here, power sits beneath the surface. Pharaoh commands the earth's treasures, and the map is a tool of that command. Every ancient map, no matter how practical, still a document of authority.

[00:10:09]Tomy's geography.

[00:10:12]Before Claudia's Tommy, the ancient Mediterranean world had a surprisingly casual relationship with maps. That might sound wrong. I mean, we associate Greece and Rome with rational inquiry and geometry. But the reality is that ancient Greeks and Romans produced few practical maps. Verbal descriptions of coastlines, yep, legal property surveys, sure. Decorative or spiritual representations of the world, occasionally. A systematic coordinate based framework for representing the known world on a flat surface. That was rare, almost non-existent actually. But Tommy changed that. working in Alexandria, Egypt around 150 AD. He was an astronomer, mathematician, and geographer. He's the author of the Almagest, his astronomical treatise, and the Geographia, which is the work that we care about in today's video. And the Geographia is not a map. That's the first thing that people get wrong about it. It's an instruction manual for making maps. It contains a theoretical framework for map projections, including two different conic projections. It includes a gazetta listing roughly 8,000 places with their latitude and longitude coordinates. The instructions are so precise that anyone living anywhere on the planet who followed Tomy's instructions with care would produce substantially the same maps. So a second century scholar in Egypt wrote a set of instructions so rigorous that someone in 15th century Florence or 21st century Tokyo following them carefully would draw essentially the same world map.

[00:11:36]That's ctography, but it's also a theory of knowledge. Tommy wasn't only a mapmaker. He was working out how information should be acquired, verified, and transmitted across time.

[00:11:46]Now, Tomy's original maps, if they ever existed as objects, they're long gone.

[00:11:52]What survives are Byzantine copies from the 13th century onward and Latin translations from the 15th century.

[00:11:57]These manuscript maps are luxurious. One world map and 26 regional maps beautifully illustrated. They were valued mainly as symbols of erudition and wealth, not for navigation. Owning a tomic atlas was like owning a complete encyclopedia. It said that you had a giant brain. But Tommy got some things oh so wrong. He underestimated the Earth's circumference by roughly 30% using about 18,000 mi instead of the true figure of 24,900 mi. That's about 29,000 km versus 40,000 km. Honestly though, this was a really long time ago.

[00:12:31]That ain't bad. He also overestimated the eastward extent of Asia. Those two errors made the Atlantic Ocean look much narrower than it actually is, which 1300 years later gave a Genoies sailor named Christopher Columbus the confidence to sail west. Columbus was working from the best available data. The data just happened to be rather badly flawed.

[00:12:50]Tomy's geographier set the template for European culty for over a thousand years. Every Renaissance map maker worked either with Tommy or against him.

[00:13:00]Nobody ignored him. And the irony is his most influential contribution was not his accuracy. It was his errors.

[00:13:09]The Heraford Mappa Mundi.

[00:13:12]To a modern viewer, medieval world maps look pretty insane. Cities in the wrong places, continents the wrong shape, people with their faces in their chests, wandering around alongside normallooking rivers. It's tempting to look at something like the Herafford Mapamundi and conclude that medieval Europeans just didn't know very much about geography. The Heraford Mapamundi is a single sheet of calf skin 1.58 x 1.34 m that's roughly 5x 4 1/2 ft and it has been displayed in Heraford Cathedral in England since approximately 1300 AD. It is the largest surviving medieval mapundi. It was created around 1285 to 1300 and it's attributed to Richard of Haldingham, also known as Richard Deello, a cleric associated with Link Cathedral. What's on it? Well, approximately 420 named places, 15 biblical events, 33 animals, both real and mythical, 32 plants, 32 peoples and tribe, including the blemier, headless men with faces in their chests, and the skyods, one-legged creatures who use their enormous foot as a sun shade.

[00:14:15]Right. Jerusalem sits at the center.

[00:14:17]East is at the top which is where the word orientation comes from by the way via the Latin orans meaning east. The garden of Eden appears at the very top edge. Christ presides over the last judgment in the border above. This is not a chart for getting from London to Rome. Scholars describe it as a book on a single page. It's an encyclopedia, a biblical commentary, a beastiary, a travel account, and a devotional object.

[00:14:43]all encoded in vaguely ctographic form.

[00:14:46]Geography here is theology. Every mountain, river, and monstrous tribe has moral meaning. The world is a story, and this map's telling it. So, how did it survive? Well, that's mostly through luck. The Bapamundi made it through the English Reformation and the English Civil War by being stored folded up in a cathedral library. In 1988, the Heraford Cathedral chapter considered selling it at auction to fund urgent building repairs. A public outcry followed and a2 million pound grant from the National Heritage Memorial Fund kept it in place.

[00:15:17]It now sits in a purpose-built display.

[00:15:19]Ultra high resolution digital imaging from 2021 to 2023 has made the map accessible worldwide for the first time and fueled new debates over its iconography and details that previously couldn't been seen without magnification. So why after all that explanation is it still mysterious?

[00:15:36]Well, that's just because medieval people were organizing knowledge in a way that's pretty alien to us today. To a 13th century viewer, the blemier and the sciods were as real as France. Sin, salv the dudes with their heads in the Okay. Sin, salvation, and the monstrous unknown occupied real space on the earth, not metaphorical space. The Heraford map is a window into a world view where geography and belief were inseparable.

[00:16:04]The Kangido map.

[00:16:07]Western histories of ctography have a habit of treating the story of mapmaking as though it started in Greece, paused for the Middle Ages, and then picks back up in Renaissance Italy. Everything else kind of a footnote apparently. But in 1402, while European map makers were still drawing bleming the location of Eden and the dudes with the face in the chest, Korean scholars produced something extraordinary. The map's full name is the Honil Gangi Yukido.

[00:16:36]Oh my, which translates roughly as map of integrated lands and regions of historical countries and capitals, which despite being a mouthful is still easier than the original Korean. It was created at the Korean court under the Joon dynasty by three scholars, Kongun, Yiho, and Yimu. What they produced is one of the most important ctographic documents of the preodern world. China dominates the center, as you'd expect from a map made at a confusion court. Korea is drawn large and in detailed precision.

[00:17:06]Japan appears, though rotated southward.

[00:17:09]What catches your eye immediately, though, is what's off to the west.

[00:17:12]Africa and the Arabian Peninsula are depicted with surprising accuracy.

[00:17:16]Europe appears as a vague mass at the far edge, but the Mediterranean is fairly discernible. In 1402, no European map depicted Africa and Asia this effectively on a single chart. The chart predates the Portuguese rounding of the Cape of Good Hope by 86 years. It predates Columbus by 90. So where' the knowledge come from? And that answer would be the Silk Road. Broadly speaking, Kongun and his colleagues compiled information from Chinese maps of the Yuan and Ming dynasties, Korean geographical surveys, and Islamic ctographic data that had traveled east along the Central Asian trade routes.

[00:17:50]The African and Arabian continent almost certainly comes from earlier Islamic sources, particularly maps influenced by the work of Alrici. That's the great 12th century Arab geographer who worked at the court of the Norman King Roger II of Sicily. The Kango map doesn't prove that Korean or Chinese explorers sailed to Africa. It shows that knowledge circulated globally through intermediaries long before the so-called age of exploration. Arab geographers mapped Africa, their work traveled east, and Korean scholars compiled it alongside Chinese and local sources. The result is a world map that no single culture could have produced alone. The map is rarely featured in western histories of ctography. The European discovery narrative is incomplete without it.

[00:18:32]The Martellus map.

[00:18:36]If the Kango map shows what the east knew about the west, the Martellus map shows what Europe thought it knew about the world on the eve of a transformation. The map was made by Henrikus Martellus, a German ctographer working in Florence around 1491, one year before Columbus sailed. It's a large manuscript map approximately 2x 1.2 m about 6 1/2x 4 ft and it's now held at Yale University's Biki Rare book and manuscript library. It shows the world as educated Europeans understood it at that moment. Africa appears in full it southern Cape recently proven navigable by Bartholomew Das in 1488.

[00:19:14]Asia stretches enormously eastward drawing heavily on Tollmy's overestimates and on Marco Polo's accounts. Japan labeled Sepangu floats out there in the ocean close to where Europe's western coastline ends. Between them is a narrow-looking Atlantic that invites someone to try crossing it.

[00:19:31]There are no Americas on this map. No Pacific as we know it. Just the promise that Asia's riches are right there a few weeks sailing to the west. For centuries, the Motelis map was studied in its visible state. But in 2018, a team at Yale using multisspectral imaging, photographing the map under dozens of different wavelengths of light, revealed more than 60 previously unreadable text legends. These hidden notes describe peoples and places across Africa and Asia, many drawn from medieval legend. There are monstrous races, exotic kingdoms, fantastical beasts. Renaissance rumor and classical myth are embedded directly into the map, unseen without imaging for over 500 years. Some popular accounts have hinted that these hidden legends prove pre-Colombian knowledge of the Americas.

[00:20:17]They don't. Uh the legend summarizes medieval speculation. They describe the same marvels and monsters that European writers have been recycling since Plenny the Elder. The Martellus map shows that Columbus was working from a worldview shaped by maps like this one and ultimately by Tomy's too small earth.

[00:20:33]The Atlantic looked crossable. Japan appeared close. He had the best available data and it pointed west. The fact that the data was wrong doesn't diminish the decision. It just puts it into context. The Martellus map shows Europe's last pre-colian geographical picture. The world as it was imagined right before everything changed.

[00:20:56]The Piri Race map.

[00:20:59]Now look, if you've ever fallen down an internet rabbit hole about ancient maps, you've probably encountered this one.

[00:21:05]It's probably the most famous mystery map in the world. Depending on who you ask, it's either proof of a lost ice age civilization or a straightforward piece of 16th century Ottoman ctography. The man behind the map is Akmud Muhadin Perry, known as Pirra. Race meaning admiral. He was an Ottoman naval commander, navigator, and ctographer.

[00:21:23]Born around 1465 in Gallipoli. He had a long and distinguished career in the Ottoman Navy. And he met a rather unpleasant end executed in Cairo in 1553 on charges of retreating from a siege.

[00:21:35]Not a brilliant way to go. The map was drawn in 1513 on gazelle skin. Only a fragment survives today measuring roughly 90x 65 cm about 35x 26 in. It was rediscovered in 1929 in the top karpy palace library in Istanbul during a cataloging project directed by Gustaf Adolf Diceman the German theologian. For over 400 years, it had remained in a palace archive. So what does the surviving fragment show? the western coast of Africa, the eastern coast of South America, and various Atlantic islands. What makes the map special is Pirase himself. In the margins, in his own handwriting, he left detailed notes listing about 20 source maps he used.

[00:22:13]Arabic charts, tomic maps, Portuguese sailing charts, and most famously, a map drawn by Columbus, likely a copy of a chart from Columbus's first or second voyage, which would have been only 20 years earlier. And now, the conspiracy.

[00:22:27]In 1965, a New Hampshire history professor named Charles Habgood published a book called Maps of the Ancient Seikings. His argument was that the land mass depicted at the bottom edge of the chart was the coastline of Antarctica shown free of ice. Habgood claimed this meant that the map was copied from source charts created by a lost civilization that existed before the last ice age more than 12,000 years ago. Eric Vontanakan picked this up.

[00:22:52]Graham Hancock amplified it further.

[00:22:54]Millions of readers absorbed this idea.

[00:22:57]The problem is that modern ctographic analysis is unambiguous on this. The land mass at the lower edge of the chart is almost certainly the coast of South America, distorted and bent eastward to fit the available parchment. This was a common practice in charts of the era where coastlines were routinely warped to accommodate the shape of the animal skin that they were drawn on. The specific Antarctic features Habgood identified bays, rivers, mountain ranges match known features of Patagonia and southern Brazil far more closely than anything on the real Antarctic coastline. No ice-free Antarctic geography appears on the map. Digital pigment and surface analysis conducted in the 2010s and 2020s confirms that the map's materials and techniques are consistent with early 16th century Ottoman cottography. There's no mystery about how it was made. So what's actually impressive about this surviving chart then? Well, actually quite a lot.

[00:23:53]In 1513, an Ottoman admiral sitting in Gallipoli brought together Portuguese, Spanish, Arabic, and tomeic materials into a single coherent chart of the Atlantic world just 21 years after Columbus' first voyage. That's evidence of a serious feat of intellectual synthesis. Turkish scholarship has increasingly reframed the map as evidence of Ottoman scientific sophistication and rightly so. And the irony is that Pirase himself explains exactly what he did in his own handwriting in the margins of the map.

[00:24:23]He was a pragmatist. He assembled his references, noted where they came from, and produced the best chart he could.

[00:24:28]The conspiracy theories actually make the map less interesting. They replace a real story of global knowledge exchange with a fantasy about lost civilizations.

[00:24:40]The real story is just better.

[00:24:43]The Aron fine map.

[00:24:46]If the pirates chart gets most of the conspiracy attention, the Aron fine map runs a close second. And for similar reasons, Aron Fine Latinized as Orantius Phineas was a French mathematician and ctographer and the professor at the college Royale in Paris. In 1531, he published a double cord form or heart-shaped world map titled Nova at Integra University Orbit Descriptio or a new and complete description of the whole world. Telling it like it is. And right there along the lower edge of the map sits a massive southern continent labeled Terror Orales. It's got rivers, bays, mountain ranges, and inland features. At first glance, it looks a lot like Antarctica. The obvious question is how. No European had seen Antarctica in 1531. The first confirmed sighting wouldn't come until 1820. This was by the Russian expedition of Fabian Godly, von Bellaren, or possibly by British American sealers operating in the same year. So, did Aransifi have access to some ancient lost source that depicted the real continent? Well, no, he didn't. He imagined it. The idea of a vast southern continent, Terra Orales incognita, was a theoretical necessity in Renaissance geography, inherited directly from Tommy and from classical philosophy before him. The reasoning went like this. The land mass of the northern hemisphere had to be balanced by an equal mass in the south or the earth would essentially topple over.

[00:26:14]It's a symmetry argument, not an empirical one. Fine simply filled in the blanks with confidence, some detailed fiction. He invented the rivers, made up the bays, and pulled the mountains out of his bottom. Charles Habgood, the same professor who pushed the Antarctica theory around the pir race map, cited the fine map as additional evidence for ancient advanced knowledge. But detailed analysis shows that finds Antarctica shares almost no actual features with Antarctica. His coastlines don't match.

[00:26:43]His rivers, they're not there. What the fine map shows is how Renaissance ctographers handled the unknown. They didn't leave blank space and they didn't write, "We don't know what's here." They filled it with confident, detailed invention. The discomfort with admitting ignorance runs deep and so fine, brilliant mathematician that he was, would rather draw an imaginary consonant in loving detail than leave the lower half of his map empty. And that impulse hasn't gone away, by the way. Thank you for watching.
