Transcript
- Lucas: So we've talked a lot about Timbuktu's libraries and its scholars, but today I want to pull on a thread that's really specific: a man who built astrolabes. Ahmad al-Wangari. Luna: Like, made them with his hands? Lucas: Exactly. And he wasn't just some legend – we actually have one of his instruments. It's in a collection in Bamako, and it's one of the few surviving objects from that whole scholarly world. Lucas: The astrolabe itself is brass, about the size of a dinner plate, engraved with all these intricate scales. It's beautiful, but also functional. And it was built in Timbuktu sometime in the late fifteenth century. That's roughly the same generation as Askia Muhammad coming to power. Luna: Wait, so they were making precision instruments in Timbuktu? I thought the universities there were more about law and theology. Lucas: That's the stereotype, but the manuscripts reveal a much broader curriculum. Astronomy, mathematics, optics, medicine – all of it was studied at places like Sankore. And al-Wangari wasn't an isolated genius. There are references to other instrument makers, to people who knew how to use an astrolabe for finding prayer times and the direction of Mecca. Lucas: What's remarkable is that al-Wangari wasn't even from Timbuktu originally. His name suggests he came from the Wangara region – that's the gold-producing area to the south. But he traveled, probably for study, and ended up in Walata, which was an older center of learning. Then he moved to Timbuktu, likely because of the growing patronage of scholarship there. Luna: So he was an immigrant scholar, kind of like many of the professors we've heard about. Lucas: Exactly. And he brought with him knowledge from other places. The astrolabe itself is based on designs from the Islamic world – you have the standard plates for different latitudes, the rete with its star pointers. But he had to adapt it. Timbuktu is at about 16.7 degrees north latitude, and many standard astrolabes were built for latitudes in the Mediterranean or the Middle East. So he had to calculate new plates. Lucas: That means he had to know spherical trigonometry, and also to observe the local stars. Some of the star names on his instrument are in Arabic, but he might have incorporated local knowledge of the sky too. That's the kind of thing that gets lost – the blending of traditions. Luna: So how do we know all this about him? Is there a biography? Lucas: Not a full one. But we have fragments. His name appears in the Fondo Kati, that collection of manuscripts that Mahmud Kati's family preserved. There are also notes in the margins of other manuscripts, mentioning that al-Wangari copied a certain text, or that he taught someone. And then there's the astrolabe itself, which has an inscription – it says 'made by Ahmad al-Wangari' and a date, though the date is a bit worn. Lucas: The really interesting thing is that the astrolabe shows signs of repair. So it was used, not just a showpiece. You can see where someone re-engraved a line or adjusted a pointer. That suggests it was a working instrument, maybe for generations of scholars. Luna: So it's like a piece of scientific equipment that was actually used in the classroom? Lucas: That's the likely scenario. We know from other sources that astronomy was taught at Sankore, and that students learned how to use instruments to determine prayer times. But there's a bigger picture here – the astrolabe is evidence of a scientific culture that was connected. You see, the designs al-Wangari used are similar to those of earlier Islamic astronomers like al-Battani, who worked in the ninth century. So there was a transmission of knowledge across the Sahara, from the Maghreb and Egypt. Lucas: But it wasn't just one-way. Timbuktu was also a place where knowledge was synthesized. The scholar Ahmad Baba, who we've mentioned before, wrote about the importance of astronomy for legal matters – like determining the start of Ramadan. So there was a practical need for this science. Luna: And al-Wangari was providing the tools for that. Lucas: Yes, and that's why I think he's such a great example. He wasn't a philosopher dreaming in an ivory tower; he was a craftsman-scholar meeting a real need. His astrolabe would have been used to find the qibla, to set the times for prayers, maybe even for navigation on the Saharan caravans. It's a practical object that embodies the marriage of science and daily life. Lucas: Now, there's some debate about whether al-Wangari was the only one making astrolabes in Timbuktu. The Tarikh al-Sudan mentions a few other names, but al-Wangari is the one we have physical evidence for. That makes him unique in the history of West African science. Luna: It's amazing that it survived at all. How did it end up in Bamako? Lucas: Through a series of lucky breaks. The astrolabe was probably kept in a private library for centuries. It might have been part of the Fondo Kati itself, or maybe another family collection. In the twentieth century, it surfaced in a market in Timbuktu, and a collector bought it. Eventually it was donated to the national museum in Bamako. And it's one of the treasures they show, though it's not always on display. Lucas: But here's the thing – the survival of the astrolabe is rare, but it's part of a bigger pattern. We have thousands of manuscripts that talk about astronomy, and there are references to other instruments like celestial globes and sundials. So al-Wangari was part of a thriving scientific community. Luna: So what happened to that community? I mean, we know the Saadian invasion disrupted things, but did astronomy survive after that? Lucas: It's a complicated story. After the Moroccan invasion in 1591, many scholars were exiled, including Ahmad Baba. The intellectual life of Timbuktu certainly declined, but it didn't disappear. There are manuscripts from the seventeenth and eighteenth centuries that show continued interest in astronomy. But the kind of high-level instrument making – that seems to have died out. Maybe because the patronage dried up, or because the political instability made it impossible to sustain. Lucas: But I think al-Wangari's story is a reminder that the history of science isn't just about Europe or the Middle East. It's a global story, and places like Timbuktu were integral to it. And that's exactly why we want to keep telling these stories. Luna: Yeah, absolutely. And you know, it makes me think about how we rely on tools, like how we're recording this conversation. Lucas: Right, and that's a nice segue to something I've been meaning to mention. If you're someone who enjoys these deep dives into history, and you want to help us keep making them without ads, you can support the show at buy me a coffee dot com slash fexingo. It's a small way to keep things running, and we really appreciate it. Luna: Yeah, it's like we're using our own tools to share these stories, and every bit helps. Lucas: So back to al-Wangari. I want to talk about the technical side of his work, because there's a fascinating detail about the astrolabe's star positions. When researchers studied it, they found that some of the star coordinates didn't match the standard tables from al-Battani or other authorities. That's actually a clue. Luna: A clue to what? Lucas: To the fact that al-Wangari might have made his own observations. If he was living in Timbuktu, he would have seen a slightly different sky than what al-Battani described from the Middle East. Precession would have changed star positions over the centuries, and also the latitude difference matters. So he may have adjusted the positions based on what he saw. Lucas: And that's a big deal – it shows he wasn't just copying existing knowledge; he was actively engaging with it and refining it. That's what we call science. Luna: So he was like a hands-on astronomer, using his own observations to build a better instrument. Lucas: Exactly. And that makes the astrolabe not just a historical artifact, but a scientific document in its own right. It's a snapshot of what a fifteenth-century scholar in Timbuktu knew about the stars, and it challenges the idea that Africa was just a passive receiver of knowledge. Lucas: There's also a human angle. We know al-Wangari had students, because there are notes in the margins of manuscripts that say things like 'I read this with Ahmad al-Wangari.' One of his students went on to become a qadi in Walata. So he was part of a scholarly lineage that connected cities across the Sahara. Luna: It's like he was a node in a network. Lucas: That's the perfect word. And it's a network we can still trace through these objects and texts. The astrolabe is a physical link to that world, and it's a reminder that history is not just about dates and battles, but about people who looked up at the sky and wondered. Lucas: So next time you hear about Timbuktu, think of Ahmad al-Wangari, who not only read about the stars, but built the tools to measure them.
