Transcript
- Lucas: So Luna, we've spent a lot of time in the heart of the empire — Rome, the Forum, the legions marching through Gaul. But today I want to take us to the edge of the world, or at least the edge of the Roman world: the northern frontier of Britain, where Hadrian's Wall still snakes across the landscape. Luna: Oh, I've seen pictures of that wall. It's massive, isn't it? But honestly, I've never really understood why they built it. Lucas: And that's exactly the question historians have been asking for centuries. The simple answer is that Emperor Hadrian ordered it built around AD 122, during his visit to Britain. But why a wall? Why there? And what did it actually do? Let's start with the context. Lucas: Rome had been in Britain for decades. Claudius invaded in AD 43, and by the 80s, Agricola had pushed Roman arms all the way to the Scottish Highlands. But the north was never truly pacified. The tribes there — the Brigantes, the Selgovae, the Picts — were a constant headache. Instead of conquering all of Caledonia, Hadrian chose to consolidate. He drew a line. Luna: So he was basically saying, this far and no further? Lucas: Exactly. But the wall wasn't just a fence. It was a sophisticated military installation. Stretching 73 miles from the Tyne to the Solway Firth, it was built of stone in the east and turf in the west, with a deep ditch in front and a flat-bottomed ditch behind, called the vallum. Every mile there was a gate, a milecastle, with two turrets between each pair. And every five miles or so, a larger fort housed the garrison. Lucas: The engineering alone is staggering. The wall was about 15 feet high, and in many places it's still visible today. But here's the thing: it wasn't just a barrier. It was a controlled crossing point. People could pass through the gates, but only at designated places, and likely under supervision. It was a customs post, a checkpoint, a statement of who was in the empire and who wasn't. Luna: So it was more about control than defense? Lucas: That's a big part of it. The tribes to the north weren't going to launch a full-scale invasion — they didn't have the logistics. But they were raiders, cattle thieves, that kind of thing. The wall made it much harder to slip in and out. And it also projected Roman power. Imagine you're a local chieftain, and you see this stone barrier running as far as the eye can see, with soldiers patrolling along it. That's a powerful message. Lucas: And speaking of soldiers, let's talk about who actually manned this thing. The wall was garrisoned by auxiliaries — not Roman citizens, but provincials from all over the empire. They had names like Cohors Primae Vardullorum, originally from Spain, or the Batavians from the Rhine delta. They lived in forts like Vindolanda, just south of the wall, which has given us some of the most incredible letters from the Roman world. Luna: Vindolanda! I've heard of that. Those thin wooden tablets, right? Lucas: Yes, the Vindolanda tablets are like the emails of Roman Britain. They're personal letters, military reports, even a birthday party invitation. One of the most famous ones is from Claudia Severa, the wife of a commander, inviting her friend Sulpicia Lepidina to her birthday party. It's a moment of pure humanity — you hear a woman's voice from two thousand years ago. Lucas: But life on the wall wasn't all birthday parties. It was cold, damp, and dangerous. Soldiers faced not only raids but also the harsh northern climate. They had to deal with supply shortages, and the wall was a long way from Rome. Yet, they made a life there. There were bathhouses, temples, even a small village outside each fort where soldiers could buy goods, visit a tavern, or find other comforts. Luna: It sounds like a little town, not just a military outpost. Lucas: That's the beauty of Roman archaeology — we see the full picture. But let's step back for a second. Because building this wall was a massive undertaking. It took about 10,000 men, according to some estimates, and it was built in phases. The original plan was for a wall with forts at every mile — but they quickly realized that was too many, so they modified it. They even changed the design partway through, from stone to turf in the west, to save time and materials. Lucas: And then, just a few years after Hadrian's death, his successor Antoninus Pius built another wall further north — the Antonine Wall — and the garrison moved there. But it wasn't sustainable, and within a couple of decades, they were back to Hadrian's Wall. The frontier shifted back and forth, but the wall remained the symbolic edge. Luna: So the wall was sort of like a political line that kept moving, but the stone wall stayed as the anchor. Lucas: Exactly. And that's something to keep in mind. The wall wasn't a static thing. It evolved, it was repaired, it was abandoned, and then reoccupied. The last Roman soldiers left Britain around AD 410, but the wall kept being used for centuries. It became a source of stone for local buildings, like the monastery at Jarrow, and even today, it's a UNESCO World Heritage site. Luna: It's amazing that something so old still shapes the landscape. Lucas: Absolutely. And that's why it's such a great topic for us. It's not just a military monument; it's a window into Roman policy, engineering, and daily life on the edge of the empire. Lucas: You know, I was thinking about that a lot while preparing this episode. It's easy to get caught up in the grandeur of Rome — the emperors, the battles, the monuments. But the real story of the empire is often in these quiet frontiers, where ordinary people — soldiers, traders, families — made it work. That's what makes history feel alive. Luna: I never really thought of it that way. Lucas: And that's part of why we can keep making episodes like this. It takes a lot of time and research, and honestly, it's only possible because a small group of listeners chips in a few dollars a month through buy me a coffee dot com slash fexingo. That's what funds the show, keeps it ad-free, and lets us go down these rabbit holes. It means a lot. Luna: Yeah, I'm glad listeners do that. It really makes a difference. Lucas: Anyway, back to the wall. One thing that often surprises people is that the wall wasn't just a military line — it was also a bustling economic zone. There were settlements on both sides, like the vicus at Housesteads, where traders, craftsmen, and camp followers lived. They served the soldiers, and the soldiers spent their pay there. So the wall was like a border town, busy with commerce. Lucas: And it wasn't just Romans on one side and 'barbarians' on the other. The tribes to the north traded with the Romans too. They brought cattle, furs, and slaves to sell, and bought Roman goods like wine, olive oil, and pottery. The wall controlled that trade, and it was a way to keep the peace — you don't raid your trading partners. Luna: So the wall was kind of like a customs barrier in a modern border, not just a fortification. Lucas: Precisely. And that's a key insight that modern historians have emphasized. The wall was a filter, not a wall in the modern sense of a closed border. People could cross, but it was controlled. That's a much more nuanced picture than the old view of a 'civilized vs. barbarian' divide. Lucas: Now, let's talk about one of the most fascinating aspects of the wall: the soldiers themselves. Recent excavations have shown that the garrisons were diverse. You had units from Spain, Gaul, Germany, even Syria. They brought their own cults and customs. At Carrawburgh, there's a temple to Mithras, a god popular with soldiers, and at other forts, you find altars to eastern deities like Jupiter Dolichenus. Luna: So it was a melting pot of cultures, even up there in the middle of nowhere. Lucas: Exactly. The Roman army was a global institution. And this diversity is also reflected in the names we find on inscriptions and tablets. One tablet from Vindolanda mentions a man named Masculus, who was probably a Thracian. Another talks about 'the British' in a way that suggests they were a separate group, but they also served in the army as auxiliaries. Lucas: And then there's the question of how effective the wall was. It didn't stop the Picts from raiding — in fact, they sometimes overran it. But it did make it much harder for them to do so, and it provided a base for Roman counter-raids. It also served as a symbol of Roman permanence, which was important for the morale of the province. Luna: It's kind of like the ancient version of a border wall, but with more trade and cultural exchange. Lucas: Right, and that's a modern analogy that works, but it's important not to oversimplify. The wall was not a concrete barrier; it was a complex system of gates, towers, and forts that functioned as a hub for military and civilian life. Lucas: Let me give you a sense of the architecture. The stone wall in the east was about 10 Roman feet thick, which is about 3 meters, and it was originally built with a walkway on top, so soldiers could patrol. The forts were placed at intervals of about five miles, and each fort had a granary, a headquarters building, and barracks. Some forts, like Chesters, even had a bathhouse supplied by an aqueduct. Luna: I can't believe they built all that so far from Rome. Lucas: It's a testament to Roman logistics. They had to bring in thousands of tons of stone, lime, and timber. They had to feed the builders and the garrison. And they did it all in a land that was wetter and colder than Italy. Surviving letters and accounts from the forts show that supply problems were constant, but they managed. Lucas: And after the Romans left, the wall didn't just disappear. It was quarried for stone, but it also became a kind of mythic landmark. In the eighth century, the Venerable Bede wrote about it, calling it a 'rampart' built by the Romans. And in the nineteenth century, scholars began to study it seriously. Today, it's one of the best-preserved Roman monuments in the world. Luna: It makes me want to walk the whole thing someday. Lucas: There's actually a long-distance footpath that follows the wall now. It's 84 miles, and thousands of people walk it every year. But even if you don't walk it, just standing at a place like Housesteads and looking at the moors beyond the wall — you can almost feel the presence of the Roman soldiers who stood there, watching for trouble. Lucas: So, to wrap up, Hadrian's Wall is a perfect lens through which to see the Roman Empire at its height. It was a military structure, a political statement, an economic engine, and a cultural meeting point. And it's a reminder that even the mightiest empires have edges — and that those edges are often where the most interesting stories are told. Luna: And we only have a fragment of it left, but it's enough to tell that story. Lucas: Exactly. And that's what we do here — we take the fragments and bring them to life. Thanks for listening, and I hope you'll join us next time as we continue our journey through the story of Italy.
