Transcript
- Lucas: So we've talked a lot about Timbuktu's manuscripts—the chronicles, the legal opinions, the astronomy. But there's one genre we've barely touched: geography. Luna: Geography? Like maps? Lucas: Exactly. And not just any maps—a full-blown mappa mundi, a world map, written by one of Timbuktu's greatest scholars: Abd al-Rahman al-Sa'di. He's the guy who wrote the Tarikh al-Sudan, which we've referenced a dozen times. But he also wrote a geographical work that's now lost. Luna: Wait, lost? So we don't have it? Lucas: We have fragments—references in other manuscripts, quotations, descriptions. Enough to know it existed and what it covered. Al-Sa'di completed his Tarikh al-Sudan around 1655, but this geography might have been earlier, maybe 1630s. He called it something like 'The Clarification of Lands and Regions'—the exact title is debated because the manuscript itself hasn't been found. Lucas: Now, before I dive into that, I want to say something. This is a history show, and we deliberately don't run ads on these episodes. If you want to support that choice—keep it ad-free—the link is buy me a coffee dot com slash fexingo. It's a small thing that makes a big difference for us. Luna: Yeah, it really does help us keep these conversations going. Lucas: So back to al-Sa'di's map. The fragments we have come from later scholars who quoted him, especially from the Sankore tradition. One reference describes the map as showing the entire known world from the Atlantic to China, with Timbuktu at the center. Luna: At the center—so it was Eurocentric but, like, reversed? Lucas: Not exactly Eurocentric. It was Afrocentric in a very literal sense: al-Sa'di placed the Niger River and the Sahel as the axis. He drew from Islamic cartography, sure—scholars like al-Idrisi and Ibn Battuta—but he also added local knowledge: the salt mines of Taghaza and Taoudenni, the gold fields of Bambuk and Bure, the trade routes to Cairo and Fez. Luna: So it was a practical map, not just theoretical. Lucas: Exactly. Timbuktu was a hub for trans-Saharan trade, so a map wasn't just an intellectual exercise—it was a tool. Merchants, scholars, pilgrims all needed to know distances, watering holes, safe passages. Al-Sa'di's map probably included that kind of detail. Lucas: We also know from a later scholar, Muhammad al-Mustafa al-Wangari—we've talked about him before—that al-Sa'di's geography was used in the Sankore curriculum. Students copied sections, added notes. So it wasn't just a single map; it was a living document. Luna: So why did it disappear? The Moroccan invasion? Lucas: Probably. The Saadian invasion of 1591 devastated Timbuktu's intellectual life. Many manuscripts were burned or taken as loot. Al-Sa'di was born after the invasion—he was writing in the 1630s–50s—but the instability continued. And later, in the 19th century, when European explorers like René Caillié visited, they reported that many old manuscripts had been lost to humidity, insects, and neglect. Lucas: But there's a twist. In the 1970s, a cache of manuscripts was discovered in a cave near Timbuktu—the so-called 'Timbuktu manuscripts' that later survived the jihadist occupation. Some of those are still uncatalogued. It's possible al-Sa'di's geography is in there, waiting. Luna: That would be incredible. Are people looking for it? Lucas: There are projects—the Ahmed Baba Institute, the Mamma Haidara Library—they've digitized tens of thousands of manuscripts. But with over 100,000 items in private collections, it's slow work. Al-Sa'di's map might be in a family library, unrecognized because the title page is missing. Lucas: What's fascinating is that al-Sa'di wasn't the only Timbuktu scholar writing geography. There was also a work by Ahmad Baba—we've talked about him—who wrote a geographical treatise as part of his legal opinions, describing the boundaries of the Muslim world for fatwa purposes. Luna: So geography was tied to law? Lucas: Absolutely. To issue a fatwa, a qadi needed to know where a traveler had been, what regions were under Muslim rule, what trade goods were permissible. So maps had legal weight. Al-Sa'di's work probably served both scholarly and practical purposes. Lucas: One fragment we have quotes al-Sa'di describing the city of Gao as 'the gateway to the east.' He talks about the Niger River bending like a snake, and he gives distances between cities in days of travel, not miles. That's typical of Sahelian geography—it's about time, not linear measurement, because terrain changes. Luna: That's so different from how we think of maps today. Lucas: Right. European maps of the same period were becoming more mathematical—projections, latitudes. Al-Sa'di's was relational: a web of places connected by trade and pilgrimage. And it was oriented eastward, toward Mecca, not northward like European maps. Lucas: We also know that al-Sa'di included the Atlantic coast. He described the 'Sea of Darkness'—that's the Atlantic—and mentioned European ships appearing off the coast, which he called 'the Franks.' So he was aware of the Portuguese and maybe the Dutch. Luna: So his map was updating in real time. Lucas: Exactly. Timbuktu wasn't isolated. Scholars there knew about the Reformation, the Ottoman Empire, the Moroccan sultanate. Al-Sa'di's map was a snapshot of a connected world. Losing it is like losing a window into how 17th-century West Africans saw the planet. Luna: What would it take to find it? Lucas: Systematic cataloguing of private collections, and luck. There's a project called the Tombouctou Manuscripts Project that's been working since the 1990s. But many families are wary—they've hidden manuscripts for centuries, especially after the jihadist occupation. Trust is hard. Lucas: And there's always the chance that it's gone forever. But even the fragments we have—just knowing that al-Sa'di wrote a mappa mundi—forces us to rethink what we think we know about African intellectual history. This wasn't a culture that only received knowledge; it produced and mapped it. Luna: I hope one day we can say 'found it' instead of 'lost.' Lucas: Me too. And if anyone listening is a manuscript scholar or knows someone with access to private libraries in Timbuktu… well, that would be the discovery of a lifetime.
