- Lucas: So before we jump in, let me just orient us. We've done a lot of episodes on the conquests — the Mongols, the Russians, the Soviets, the whole Great Game stuff. But there's this moment in between, roughly the 15th century, when Central Asia wasn't just being fought over — it was producing some of the most advanced science and art in the world. I'm talking about the Timurids, and specifically Ulugh Beg, Timur's grandson. Luna: Ulugh Beg — that's the astronomer, right? The one with the giant observatory in Samarkand? Lucas: Exactly. And that observatory is key. But let's back up just a second. After Timur died in 1405, his empire was split among his sons and grandsons. One of them, Shah Rukh, took over the eastern part, centered in Herat. But his son Ulugh Beg was given Samarkand as his appanage. And Ulugh Beg was not really a warrior — he was a scholar. He built a madrasa, actually two — one in Bukhara and one in Samarkand — and then, around 1424, he started building an astronomical observatory. Luna: Was that common? A prince building an observatory? Lucas: Not at all. I mean, there were precedents — the Ilkhanid observatory at Maragheh in the 13th century, built under Hulagu. But that was more of a state project. Ulugh Beg's was personal. He was genuinely fascinated by the stars. He studied under a Persian mathematician named Al-Kashi, who was one of the greatest calculators of the medieval world. Al-Kashi computed pi to sixteen decimal places — that's more accurate than anything in Europe until the 16th century. And Ulugh Beg himself wrote a star catalogue, the Zij-i Sultani, which listed the positions of over a thousand stars with incredible precision. Luna: A thousand stars? How did they do that without telescopes? Lucas: With massive instruments and careful naked-eye observation. The centrepiece of Ulugh Beg's observatory was a huge sextant — basically a giant arc set into the ground, about 40 metres in radius. It was used to measure the altitude of stars as they crossed the meridian. And they had other tools — astrolabes, armillary spheres. But the key was the scale: the bigger the instrument, the more precise the measurement. That sextant was so well built that it survived in fragments until modern archaeologists excavated it in 1908. Luna: Wait — it survived underground? Like, it wasn't destroyed? Lucas: That's the thing. After Ulugh Beg was assassinated in 1449, the observatory fell into disuse. Over the centuries, it got buried under rubble. People forgot where it was. But in the early 20th century, a Russian archaeologist named Vasily Vyatkin — who was actually a schoolteacher — found references in old texts and started digging. And there it was, a giant curved trench carved into the earth, lined with marble. So today you can visit it, just outside Samarkand, and see the foundations of that sextant. It's pretty humbling. Luna: I've seen pictures of the Registan — those blue tiles. But I didn't know there was a science hub underneath all that beauty. Lucas: That's exactly the point. The Registan square we see today — those three madrasas — the Ulugh Beg madrasa was the first one built, around 1420. And it wasn't just a religious school. They taught mathematics, astronomy, geometry. The facade is covered with those geometric star patterns, which are actually mathematical in design. So the architecture itself is a statement: this is a place where science and faith coexist. But that coexistence was fragile. Luna: What do you mean? Did the clergy push back? Lucas: Yes, especially after Ulugh Beg died. He was seen as too secular, too focused on the stars. There's a story — maybe apocryphal — that his own son, Abd al-Latif, had him killed because of pressure from religious conservatives. Abd al-Latif ruled for only six months before he was killed himself. After that, the Timurid dynasty fragmented, and scientific inquiry declined. The observatory was eventually stripped of its instruments, and the knowledge was scattered. Some of it ended up in the Ottoman Empire, some in India. But the golden age of Samarkand astronomy was over. Luna: So the 'Timurid Renaissance' — was it really a renaissance like in Europe? Lucas: It's a loaded term. There certainly was a flourishing of arts and sciences under the Timurids — not just astronomy, but also miniature painting, calligraphy, tilework, poetry. The historian Sharaf al-Din Ali Yazdi wrote the Zafarnama, a biography of Timur, which is a masterpiece of illuminated manuscripts. And the architectural legacy — the Bibi-Khanym Mosque, the shah i zinda complex in Samarkand — those are world heritage sites. But it wasn't a 'rebirth' in the European sense. It was more of a continuation and intensification of Persian-Islamic traditions, with some Chinese influences — because the Timurids had contact with Ming China. Ulugh Beg even invited Chinese astronomers to Samarkand to collaborate. Luna: Chinese astronomers — that's fascinating. Did they share data? Lucas: Yes, there's evidence that Chinese astronomers visited Samarkand in the 1420s, and there were exchanges of techniques. The Zij-i Sultani actually includes some Chinese calendrical methods. So it was a genuinely global scientific enterprise, centuries before the so-called 'Scientific Revolution' in Europe. But because it didn't lead to the same kind of institutionalized science — no printing presses, no universities that survived — it faded from memory. That's why we're talking about it now: to remember that Central Asia was once at the cutting edge. Luna: And the star catalogue — did it influence later astronomers? Lucas: It did, indirectly. Copies of the Zij-i Sultani reached the Ottoman Empire and were used by the astronomer Taqi al-Din in his Istanbul observatory in the 1570s. And it's possible that some of the data made its way to Europe through the Silk Road and later through the Mughals — Babur was a Timurid, after all. But by the time European astronomy took off with Copernicus and Kepler, the Timurid star catalogue was mostly a historical curiosity. Still, when you look at the precision of Ulugh Beg's measurements — he calculated the length of the sidereal year to within a minute of modern values — it's astonishing. Luna: That's incredible. So why isn't he more famous? Why don't we learn about him in school? Lucas: Part of it is Eurocentrism. The standard narrative of the history of science goes from ancient Greece to the Islamic Golden Age — usually stopping around the 13th century — and then jumps to Renaissance Europe. The Timurids fall through the cracks. Plus, the observatory was destroyed, so there's no direct line of continuity. But also, in Uzbekistan itself, after the Soviet period, there's been a revival of interest. Ulugh Beg's face is on the 500 som note, and there's a university named after him. But the story is still being pieced together. Luna: So when I go to Samarkand, what should I look for? Beyond the Registan? Lucas: Definitely the Ulugh Beg Observatory museum. It's a short ride from the city center. You can see the remains of the sextant trench, and there's a small museum with replicas of instruments. Also, the gur e amir mausoleum — that's where Timur and Ulugh Beg are buried, along with other Timurids. The tilework inside is stunning. And if you go to the Registan, look at the Ulugh Beg madrasa closely — the star patterns on the tiles are actually based on complex geometry. There's a whole mathematical code embedded in the design. Luna: A mathematical code — like, hidden meaning? Lucas: Not hidden, exactly, but the patterns are built using a system of geometric proportions that reflect Islamic mathematical concepts. Some scholars argue that the designs encode astronomical ratios — like the proportions of the planets' orbits. It's speculative, but it shows how deeply intertwined art and science were. The Timurids didn't separate them the way we do. Luna: That changes how I see those tiles. Lucas: Exactly. And that's the takeaway from this episode: Central Asia wasn't just a crossroads of trade; it was a crossroads of ideas. The Timurid Renaissance was real — it just didn't last. But its remnants are still there, in the tiles, in the star maps, in the madrasas. And if you know where to look, you can feel that moment when a prince looked up at the sky and wanted to measure it. Luna: I think I need to book a ticket to Samarkand. Lucas: Do it. And bring a good pair of walking shoes — and maybe a star chart. Luna: Thanks, Lucas. That was a beautiful picture of a world I knew almost nothing about. Lucas: My pleasure. It's one of my favourite corners of history. And I'm glad we finally got to share it.
