The Caliph Sent Fifty Men to Find the Wall of Gog and Magog — One Came Back (842 AD)

[00:00:00]In the winter of 842, a man woke in a palace on the Tigris and could not stop shaking. He was the most powerful person alive. His grandfather had been Haron al- Rashid, the caiff of a thousand1 knights. His city Samara was younger than he was, raised out of bare desert north of Baghdad to house an empire that reached from the mountains of Spain to the rivers of India. And he had dreamed that a wall at the edge of the world had cracked. Not a wall he had ever seen, a wall from scripture, the barrier that held back the end of everything. [music] Before the sweat had dried on him, he sent for the one man in his court who was said to speak 30 languages. And he gave that man 50 soldiers a chest of silver and a single instruction. Go to the end of the map, find the wall, come back and tell me whether it still holds.

[00:00:50]28 months later, a handful of ruined men walked back into Samara. Most of the 50 were not with them. And the one whose voice survived, the interpreter, sat down in front of the caiff and described in careful, sober detail a thing that should not be describable. An iron gate between two mountains at the far end of the earth, a lock the size of a man, and a guard who climbed a ladder every week to strike the iron with a hammer and pressed his ear to the metal and listened for what was moving on the other side. That interpreter was a real person. The journey is a documented event and the man who wrote it down was not a poet or a preacher. He was the head of the caiff's intelligence service and he claimed he heard the account from the survivor's own mouth. His name was Iben Cordadbe and his job was the Bid, the Abbassid postal and intelligence network, the nervous system of the empire. A postmaster in that world was not a cler. He was the man who knew the roads, the distances, the garrisons, the prices, the names of every ruler between the capital and the frontier. Around the year 870, Iban Cordadbe compiled all of it into a single book, the Karab al- Masalik Walmik, the book of roads and kingdoms. It is one of the oldest surviving works of Arabic geography. And for the most part, it reads exactly like what it is, a dry administrative register of stages and tolls and troop postings. The least romantic document imaginable and then folded into the middle of this ledger of roads is the account of Salam the interpreter sent by the Khalif Alwathik to find the barrier of Gog and Marog. Iben Cordadbe states plainly that he had it from Salam directly and that he had also seen the written report Salam submitted to the caiff. He was in other words the imperial official whose entire profession was verifying claims about distant places recording a claim about the most distant place of all. He did not present it as legend. He filed it beside the tax rates. That is the detail that should stop you. A tale about the wall at the end of the world entered into the empire's own logistics manual by the empire's own spy master who says he interviewed the survivor. To understand why a kelliff would spend a fortune and 50 men chasing a wall, you have to understand that in the 9th century the wall was not a myth. It was geography. It was on the map the way a mountain range is on the map. a fixed feature of the known world positioned at its northeastern rim holding something back. The barrier comes from the 18th chapter of the Quran, the Surah of the cave. In it, a figure called Dul Carnain, the two-horned one, travels to the ends of the earth. He reaches a place between two mountains where he finds a people who can barely understand speech and they beg him for help. Yajooj and Majooj, Gog and Magog, are ravaging their land, and they offer him tribute to build a defense. He refuses the payment. Instead, he asks them for iron.

[00:03:46]He fills the gap between the two mountains with blocks of it, sets his men blowing on the fire until the iron glows like fire itself, and pours molten copper over the whole mass so that the raiders can neither climb it nor dig through it. And then, Dulkanain says something that turns a fortification into a countdown. This he says is a mercy from my Lord. But when the promise of my Lord comes, he will level it to the ground. And the promise of my Lord is true. Read that again because it is the engine of the entire story. [music] The wall is not permanent. It is a temporary measure. Scripture says explicitly that one day it will fail, that Gog and Magog will pour out again, and that their release is one of the signs of the last days. So the wall is not just a place on the map. It is a clock. and a crack in it is not vandalism. It is the alarm. This idea did not begin with the Quran and that is what gives it its weight. Gog and Magog are older than Islam, older than Christianity, older than the road Salom would ride. They're in the book of Ezekiel, a horde out of the far north that descends upon a land at rest.

[00:04:51]They're in the book of Revelation, loosed at the end of the thousand years to make war and gathered for a final destruction. And a few years before the Quran was revealed, a Syriak Christian text now called the Alexander legend told of Alexander the Great, riding to a pass between two mountains at the edge of the world and there building a gate of iron and brass to seal the unclean nations of the north behind it [music] until the appointed time. The same mountains, the same iron, the same brass, the same clock ticking toward a foretold release. The story crosses religions and centuries and languages and keeps arriving at the identical image, a gate [music] in the far north or the northeast with something terrible pressed up against the other side of it waiting. This is why so much ink has been spilled over the identity of Dulan, the two-horned one who builds the barrier in the Quran.

[00:05:42]For most of Islamic history, the dominant view among commentators was that he was Alexander. the two horns read as the two horns Alexander wears on his coins, the world conqueror who reaches the rising and the setting of the sun.

[00:05:56]Other scholars resisted that identification and argued for a righteous king of the distant past precisely because the Alexander of the Greeks was no monotheist and made an uneasy profit. That debate has run for more than a thousand years and it is not settled now. But notice what the debate assumes on both sides. Nobody in it questions that there is a barrier.

[00:06:16]Nobody questions where it stands. They argue only about which conqueror poured the brass. The wall itself is the fixed point around which every version of the argument turns. And that fixedness is the thing to hold on to. When the great world maps of medieval Europe were drawn, the Heraford mapundi around the year 1300, the vast eptof map before it.

[00:06:36]The ctographers did not treat Gog and Magog as a story. They drew them as a location. Up in the corner of the inhabited world, behind a range of mountains and a wall, the artists inked in the penned nations by name. Sometimes shown gnoring on human limbs, always sealed off, always waiting. To a medieval mapmaker, this was not decoration, and it was not doubt. It was the same category of fact as the Nile or the Caspian. The end of the world had a shape, and at one corner of that shape was a wall, and behind the wall was the thing the wall was for. By the time mapmakers in Europe drew the great mapundi centuries later, they simply drew it in. On the Heraford map and the Ebtof map, up in the corner of the known world walled off sit the peoples of Gog and Magog waiting. Nobody drawing those maps thought they were inventing anything. They were recording a feature of the world as universally accepted as the ocean. So when the Khalif Alwathic woke from a nightmare that the barrier had split, he was not a superstitious man frightened by a bad dream. He was a ruler who had been taught by every scripture and every map he had ever encountered that a real structure stood at the edge of his known world holding back the end of days and that its failure would be sudden and catastrophic and foretold.

[00:07:52]The rational response, the responsible response was to send someone to check the lock. And this is where the story stops being about scripture and becomes about a man and a road. The man was Salom. History gives him one defining trait. He was an interpreter and an extraordinary one. The accounts say he commanded 30 languages which in that era meant he could move through the whole northern frontier of the Islamic world through Armenians and Georgians and Allens and Khazars and Turks and make himself understood at every threshold.

[00:08:23]In an empire whose reach ended where its translators ended, a man who spoke 30 tongues was not a servant. He was an instrument of state, the only kind of instrument that could survive a journey off the edge of the administered world.

[00:08:36]The caiff outfitted him the way you outfit an expedition you expect to lose.

[00:08:41]The sources record the sums with a bookkeeper's precision. Thousands of dinars for the mission. Thousands of dirhams for Salum personally. Provisions loaded onto scores of pack animals and a specific chilling item of equipment.

[00:08:55]Cladding to protect the men and their beasts against a cold so severe it is named in the packing list. You do not itemize protection against killing cold, unless you already know the road leads somewhere the sun does not reach. The caiff also sent letters ahead, [music] sealed instructions to the governor of Armenia and to the string of frontier kings beyond him, ordering each to pass this party up the line to the next [music] ruler like a bucket handed from hand to hand toward a fire nobody wanted to look at directly.

[00:09:23]They rode north out of Samara and the administered empire fell away behind them to Tifflis, the Georgian city that sat on the ragged edge of Abassad control. then handed up to the lord of the Sera in the high Caucusesus whose fortress commanded the mountain roads.

[00:09:37]Then to the king of the Allens, a people of the northern slopes, then to a ruler the sources called the Filancha, and then out of the world of Muslim vassels entirely, past the last governor who owed the caiff anything at all, and into the land of the Kazars.

[00:09:52]The Kazars matter here more than the account lets on, and their presence is one of the quiet proofs that Salam went where he said he went. The Kazak Kaganat was a genuine great power of the 9th century. A Turk empire a stride the step north of the Caucusesus controlling the corridor between the Black Sea and the Caspian. The exact gateway between the settled south and the open north from which every horde in history had come.

[00:10:16]Their ruling house had famously adopted Judaism, making them the one major state of the medieval world that was neither Muslim nor Christian, and their permission was the price of passage into the country beyond the last frontier. A fabricator inventing a route to the end of the world would not necessarily have known to route his hero through Kazar hands. Salam did because that is where the road actually ran. The historian DM Dunlop who reconstructed this leg in detail read these stages as real step geography. The itinerary of a man who had genuinely been passed up the chain of northern rulers one seal at a time.

[00:10:51]The Khazars gave them guides and with the guides the account changes character. Up to this point, it reads like every other stage in Ibn Hordadba's ledger. This king, that distance, [music] this letter, this many days.

[00:11:05]Now, the ledger cracks open, and the landscape itself begins to turn strange.

[00:11:09]They came to a land that was black and feted and dead. The account says they rode through it for many days, carrying vinegar to press against their faces and hold the stench at bay, through a country burnt and wreaking and empty of anything living. Whatever the natural explanation, a volcanic waste, a salt flat, a stretch of poisoned ground, the account does not say, and the men did not know, the effect on them was the same. They rode for days through a landscape that smelled like the end of something. And when they asked, the Khazar guides told them what they were looking at. This, they said, is the land that Gog and Magog ruined. This is what the raiders leave behind them when they come over the wall. The men understood then that they had crossed into the outer shadow of the thing itself, that they were riding the scorched margin of it, a belt of devastation laid down as a warning before the barrier so that no one could approach the wall without first passing through a demonstration of why it was built. Then the ruined cities. The account describes towns standing empty across days of riding, [music] their walls intact and their gates hanging and their people simply gone. not sacked in the way an army sacks a city. Not burned to the ground, not leveled, but emptied, hollowed, the architecture surviving, and the inhabitants vanished. They passed through these husks for days. It is a landscape that echoes across every account of Erasia ever written, and that you will recognize if you have read any of them, the shell standing, and the life inside it gone. The buildings outlasting the people who filled them. a place that remembers a population it no longer holds.

[00:12:46]Salom and his men rode through the emptied cities toward the wall. And the emptiness was itself a kind of testimony. And then at last people, fortified towns, garrisoned and alive, inhabited by Muslims who spoke Arabic and Persian, living at the very rim of the world beside the thing they existed to watch. Salam asked them in their own tongue whether anyone here had ever seen Gog and Magog with their own eyes. And they answered that no, no one saw them, because no one who looked over the barrier came back down to say what they had seen, except once, they said, long ago, when some of the creatures had appeared upon the upper edge of the wall, and a black wind had risen and thrown them back. That was the closest anyone living had come. A rumor of a face at the top of a wall and a wind.

[00:13:32]The garrison led them the final distance, and Salom described what he saw with a flatness that is somehow more convincing than any ore would have been.

[00:13:40]Two mountains and between them a gap. In the gap, a gate of iron. The construction he laid out course by course, the way a man described something he actually stood in front of and studied. Iron bricks, he said, laid like courses of masonry and bonded not with mortar, but with molten brass poured between them. So that iron and brass had fused into a single unclimbable undigable mass. The exact technique scripture had described Dulan using iron blocks welded with molten copper described now not as prophecy but as a thing a government interpreter had put his hand against. He described the threshold at the base and the great lintil across the top. He described the doors and a bolt and a lock so large it took the accounts measurements to convey and keys hung upon it that a man could barely lift. And then he described the ritual and it is the ritual more than the gate that has kept scholars awake for a century. A warden, an appointed guardian whose whole hereditary office was the keeping of this one wall, climbed a ladder set against the iron at fixed intervals and struck the metal with a hammer. The sources say three blows and then laid his ear flat against the cold iron and listened because the sound the metal gave back was the diagnosis. A gate that rang true was a gate that was whole. A change in the tone would mean the iron had been worked at, thinned, weakened from the far side.

[00:15:07]This was not superstition. It is exactly how a person tests a bell or a rail or a casting for a hidden floor. You strike it and you listen and the sound tells you the truth the eye cannot see. And Salom reported that when the warden struck the iron and pressed his ear to it, there was an answer, a stirring, a faint noise coming back through the fused iron and brass from the other side, the sound of something that had heard the hammer. The warden listened until he was satisfied the barrier still held, that the promise had not yet come due, and then he climbed down. The men who had come from the far end of the earth stood and watched a hereditary official strike a wall and listened to what answered, and they understood something that the account conveys without ever stating it. This was not a monument. Monuments do not get struck and inspected every week. This was a machine still running, still crude, still performing the single function it had been built to perform, and its function was not to be looked at. Its function was to be listened to. They turned around and went home the long way through Corusan, through Smarkand and the great cities of the east, and the road back was worse than the road out.

[00:16:16]Of the men who had ridden north out of Samara, a great many never rode back into it. Some accounts of the return are little more than a tally of the dead, cold, hunger, distance, the toll of a journey no one was built to survive twice. What came back in the end was essentially a single testimony. One voice that had gone to the wall and returned to speak. Salam reported to the caiff, and Alwathik, who had sent him on the strength of a dream, heard the confirmation that the lock still held, rewarded him, and within a few years was dead. The interpreter told the story to the spy master. The spy master wrote it into the ledger of the empire, and there it has sat for 1100 years. Now, the fair objection, and it is a strong one. This is a tale about the wall at the end of the world with a monster behind it.

[00:17:04]Everything in a modern mind, says invention. Salam had every incentive to come home with a story worthy of the fortune the caiff had spent and dead men. Do not contradict a survivor. A skeptic can read the whole account as a piece of court theater. A returning agent giving his patron exactly the confirmation the patron's dream had demanded. That reading is not foolish.

[00:17:25]It is the responsible default. And yet the account has survived a strange kind of test which is that serious scholars keep failing to dismiss it. The Dutch orientalist Michael Jander Goj who edited Ibn Hordadbear's text for publication in the 19th century wrote a study specifically on the wall of Gog and Magog and concluded that Salam's journey was not fiction that the itinerary stage by stage corresponds to real geography and real rulers and that a real expedition really went somewhere.

[00:17:53]He argued the account preserves the record of an actual voyage that reached an actual destination. However, the traveler understood what he found. The historian DM Dunlop in his 1954 study, the history of the Jewish Khazars for Princeton, traced Salam's route through Khazar territory and treated the northern legs of the journey as genuine topography, not romance. These men were not believers hunting for scripture in the ground. They were philologists and historians and they read the itinerary and could not make it come apart.

[00:18:24]The most striking modern argument comes from Kevin vanladdle, an Arabist and historian of the medieval Islamic world who was taught at Yale and elsewhere and who has written extensively on the Alexander material behind the Quranic barrier. In his study of the Alexander legend in the 18th surah published in 2008 and in his work on Salam's expedition, Vanladel makes a case that reframes the whole thing. The return route through central Asia, the descriptions, the direction of travel.

[00:18:52]He argues they fit a real and identifiable place. The western terminus of the Great Wall of China, the frontier gate the Chinese called the Jade Gate, Yummen Guan, the point where the Chinese wall system runs out into the desert of the far west. In this reading, Salam did reach a real wall between real mountains, guarded by a real garrison who really did strike and inspect it, the Chinese imperial frontier, and carried home a genuine eyewitness account, which the framework of his own faith and his own maps naturally translated into the one great wall those maps said had to be there. That is the version that unsettles me more than any monster would. Not that Salam lied, that Salam told the truth, and the truth was a real wall tended by real men who really did test its integrity, and that the thing his culture had taught him to see behind it, was simply the thing every culture in the region had already agreed was there, because whichever wall he stood before, the walls themselves are not in doubt. This is the part the skeptics and the believers both have to sit with, and it is the part that quietly dismantles the easy dismissal.

[00:19:54]Barriers of exactly this kind in exactly this region built for exactly this stated purpose to seal a gap between mountains against horsemen from the north physically exist and you can walk them today.

[00:20:08]At Durbent [music] on the Caspian coast of Dagistan stand the Cissanian fortifications the Arabs themselves called Babalabwab, the gate of gates. It is a wall that runs down out of the Caucasus and continues into the sea, closing the narrow coastal corridor between the mountains and the water. The single doorway through which the step nomads had to pass to reach the settled south. It matches the description of the Caspian gates so exactly that medieval geographers, including Muslim writers who came after Salum, identified it outright as the barrier of Dulkarnain. It is now a UNESCO World Heritage site. You can stand in its gate. It is as real as any building on Earth. Further east, across the plain south of the Caspian in northern Iran, runs the Great Wall of Gorgon, a fortification the locals have long called the Red Snake for the color of its bricks. It is roughly 195 km long, longer than Hadrien's wall and the Antonine wall combined. Studded with more than 30 forts, and fed by a canal system that watered the troops who held it. It was surveyed and dated in our own century by an international team including the University of Edinburgh archaeologist Ebahad Sauer whose work assigned it to the Cisanian Persian Empire of late antiquity and confirmed its purpose to hold back the nomadic peoples of the north. And here is the detail that should stop anyone who thinks the past is fully mapped. For most of modern history, one of the longest walls ever built by human beings sat in plain sight in a welltraveled country and was barely studied, barely dated, barely known. It took until the 21st century for archaeologists to establish what it was. A monument on that scale hiding in the open is exactly the kind of thing that makes a 900year-old account of a great northern wall harder to laugh off than it looks.

[00:21:57]And at the far end of the map, where Vanladel's argument points, the Jade Gate, Yumanguan, the western mouth of the Great Wall of China, a frontier gate tended for something like a thousand years by garrisons who did precisely what Salam's warden did. They watched the pass. They maintained the wall. They kept the north on the far side of it generation after generation as a matter of imperial routine. So the pattern that emerges is not the one you expect. It is not a story about whether a monster is real. It is a story about a belt of enormous walls thrown up across the entire northern frontier of the civilized world by separate empires who did not coordinate. Persians at Durbent, Persians at Gorgon, Chinese at Yummen.

[00:22:44]Every one of them built to seal a gap between mountains against a horde from the north. Every one of them guarded and inspected and maintained across centuries. and a shared conviction running through Ezekiel and Revelation and the Sierak legend and the Quran and every medieval map that somewhere along that belt of walls, one gate in particular held back not merely raiders but the end of the world. I have gone back and forth on what to do with this.

[00:23:11]The easy move is to pick a side [music] to call Salum a liar and be done or to call the wall literal and thrill the part of the audience that wants it to be. Both are cheap and both miss what is actually strange here. What is strange is not the monster. What is strange is the convergence. Independent civilizations out of contact with one another. All built the same kind of wall in the same kind of place for the same stated reason. Independent scriptures written across a thousand years in three languages all placed the same barrier at the same edge of the world holding back the same thing. And a real imperial expedition funded and provisioned and recorded by a real government [music] went to check on it. And the survivor came home and described without drama a gate exactly like the one scripture had described 8 centuries before he was born. You do not have to believe a single supernatural word to feel the floor tilt slightly when all of that lines up. The question is not whether Gog and Magog are behind a door in Dagasan. The question is why so many different peoples for so many centuries were so certain that something was and built accordingly.

[00:24:22]Because look at what the barrier actually is in every version of the story. It is temporary. Scripture is emphatic on this point in a way people rarely notice. Dularn does not build an eternal wall. He builds a wall with an expiration date and he says so out loud the moment he finishes it. that when the promise of his lord comes, it will be leveled to the ground.

[00:24:45]The garrison Salom met did not strike the iron once and walk away. They struck it again and again, week after week, generation after generation, because the whole terror of the thing was that it could fail, that the failure would be sudden, and that the only warning would be a change in the sound the metal made.

[00:25:03]The wall was never a solution. It was a vigil, a thing that had to be watched forever. Because the moment everyone stopped watching was the moment it was designed to be tested. And that is the sentence I cannot get out of my head.

[00:25:17]Somewhere along the northern frontier of the old world stood a gate that a man was appointed to strike with a hammer and listen to [music] forever because the sound it made was the only thing standing between the ordinary world and whatever was on the other side. And one day in every version of the story, no one is there to strike it anymore. The caiff who sent the expedition has been dead for 1100 years. [music] The interpreter who walked to the wall and back told his story once to one man and then vanished from history so completely that we do not know where or when he died. The empire that could send 50 men to the end of the earth to check Lock is gone. Its capital a field of ruins on the Tigris. But the account survived filed between the tax rates in a spy master's ledger because Iben Cordbe could not bring himself to leave it out and neither could de Goj and neither could Dunlop and neither could Vanlad.

[00:26:09]Every generation of serious people who has picked it up has tried to explain it away and has ended up instead drawing a careful map of a real journey to a real wall. The walls are still standing. That is the part that stays with me the same way it stays with me in every one of these stories. Debent still runs down to the Caspian. The red snake still crosses northern Iran, most of it unexavated, surveyed only in the last 20 years by a handful of archaeologists who happen to look. The jade gate still stands in its desert. The hardware persists. What is gone is the watch. Nobody climbs those walls now to strike them and listen.

[00:26:47]Nobody presses near to the iron. The garrisons dispersed. The wardens died.

[00:26:53]The hereditary office of listening to the metal ended so long ago that we have forgotten it was ever a job a man could hold. So here is what I keep asking, and I do not have an answer, only the account and the walls, and the strange refusal of both to disappear. What did the warden hear when he laid his ear against the iron? What was the sound that told him the barrier still held?

[00:27:14]And what would it have sounded like on the day it did not? Why did every empire on that frontier out of contact with each other arrive at the same wall in the same place for the same fear? And if the whole point of the thing in scripture and in stone alike was that it was temporary, that it required an endless vigil, that its failure would be sudden and foretold, then what does it mean that we are the generation that finally stopped listening? A man rode to the end of the world in the year 842 and put his hand against an iron gate. Most of the men who went with him did not come home. The one who did described a guard and a hammer and a sound coming back through the metal from the other side. He told it plainly the way you tell the truth and the empire wrote it down. And 11 centuries of scholars have failed to prove it never happened. The wall is still there. The listener is gone. And nobody alive can tell you what the iron would say now if someone climbed up in the cold at the edge of the map and struck it three times and pressed an ear to it and waited.
