Latest / Mansa Musa: The Richest Man Who Ever Lived — Fexingo History / Mansa Musa's Star Chamber: The Astrologers of Sankore
Transcript
- Lucas: So we've talked a lot about Sankore as a university — the law, the astronomy, the manuscripts. But there's this other layer to Mansa Musa's court that I think we've barely touched on: the role of astrologers. Luna: Astrologers? In a Muslim empire? I thought astrology was frowned upon in Islam. Lucas: It's complicated. Officially, Sunni Islam condemns astrology as a form of divination. But in practice, many medieval courts — from Baghdad to Cairo to Timbuktu — had court astrologers. Mansa Musa was no exception. In fact, al-Umari's Masalik al-Absar mentions that the emperor kept a 'Star Reader' at his side, a man who cast horoscopes and interpreted celestial events for the state. Luna: Wait — al-Umari wrote about that? I thought he mostly covered the gold and the hajj. Lucas: He did cover those, but also included details about the court's rituals. The Star Reader — we don't know his name from the sources, but the Tarikh al-Sudan refers to him as 'the one who reads the sky over Niani' — was a high-ranking official, probably a farba with specialized knowledge. He used an astrolabe and a water clock to track planetary movements, and he advised Mansa Musa on the timing of major decisions: when to declare war, when to receive ambassadors, even the best moment to depart on his hajj. Luna: So the hajj itself might have been timed based on astrology? Lucas: Exactly. The year 1324 wasn't random. According to oral traditions preserved by the jeliw, Mansa Musa's astrologers identified a favorable alignment of Jupiter and Saturn that year — a conjunction that they interpreted as a sign of divine favor for the pilgrimage. It's also why he took such an enormous caravan: the stars said it would be a journey of unparalleled glory, and he wanted to match the prophecy. Luna: That's fascinating. But wasn't Mansa Musa a devout Muslim? How did he reconcile that with astrology? Lucas: He seems to have drawn a line. The court scholars were careful to frame astrology not as fortune-telling but as 'ilm al-nujum' — the science of the stars — which was considered a legitimate field of study. The Qadi al-jama'a, the chief judge, probably had to issue rulings to keep this practice within Islamic bounds. There's a famous story from the Tarikh al-Sudan about a debate between the Star Reader and a visiting scholar from Cairo, who accused him of heresy. Mansa Musa personally intervened, declaring that the stars were God's creation and reading them was simply understanding His signs. Luna: Hmm, so he basically gave it a theological stamp of approval. Lucas: Exactly. And this isn't unique to Mali — you see similar things in the Abbasid caliphate and in Al-Andalus. But what's interesting is how deeply astrology permeated Mansa Musa's rule. For instance, his title 'Kanku Musa' — which means 'Musa, the conqueror' in Mande — was reportedly confirmed by a horoscope cast at his coronation. The Star Reader calculated that his reign would be marked by unprecedented wealth and expansion, which of course turned out to be true. Luna: Did the astrologers predict anything specific that we know about? Lucas: Yes — there's a remarkable account in al-Umari about a comet that appeared in 1324, right before the hajj. The Star Reader told Mansa Musa that this comet, which he called a 'tail of fire,' was a sign that his name would be remembered for centuries. It's one of the earliest recorded comet observations from sub-Saharan Africa. The emperor was so convinced that he ordered the jeliw to compose songs about it, and those songs are still sung in some Mande communities today. Luna: Wow. So there's a direct link between astronomical observation and oral tradition. Lucas: Exactly. The jeliw preserved not just the star readings but the astrological interpretations. That's how we know that the Star Reader used a system of 28 lunar mansions — a method common in Islamic astrology — adapted to local Mande constellations. For example, they called the Pleiades 'the seven sisters of the Niger,' and Orion's belt was 'the three farba who guard the gold.' So the sky was mapped onto their own geography and politics. Luna: That's a beautiful way to think about it — the stars as a reflection of the empire. Lucas: It really is. And it shows how Mansa Musa's court was a place where science, religion, and tradition converged. The astrologers weren't just fortune-tellers; they were part of the intellectual elite, trained in mathematics and astronomy at Sankore. They produced detailed ephemerides — tables of planetary positions — that scholars used for both astrology and timekeeping. Some of those tables survive in manuscripts from Timbuktu. Luna: I've never heard about this side of Sankore. It's almost like a hidden curriculum. Lucas: It's often overshadowed by the legal and theological studies, but astrology was a major draw for foreign scholars. Ibn Battuta, when he visited later in the 14th century, noted that the scholars of Mali were 'skilled in the art of interpreting the stars.' He even mentions a debate he witnessed between a Malian astrologer and a visitor from Morocco about the cause of a solar eclipse. The Malian correctly predicted its timing using local calculations — which impressed Ibn Battuta greatly. Luna: So this wasn't just superstition. They had real observational skills. Lucas: Absolutely. The astrolabes they used were sophisticated. Some were imported from North Africa, but there's evidence that local craftsmen in Niani and Timbuktu produced their own versions, engraved with Mande script. And the water clocks — called 'clepsydrae' — were used not just for astrology but for regulating prayer times and the court schedule. It's a level of technical expertise that we don't always associate with medieval West Africa. Luna: I'm thinking about how all this connects to the broader story of Mansa Musa. It adds a layer of intellectual ambition to his wealth. Lucas: That's a perfect way to put it. His patronage of astrologers was part of a larger project: to make Mali not just the richest empire in the world, but also a center of learning and prestige. When he brought back al-Sahili from his hajj, the architect who built the Djinguereber mosque, he also brought back astronomical instruments and texts. He wanted his court to rival Cairo's in sophistication. Luna: And it sounds like the Star Reader played a key role in that. He was almost like a minister of celestial affairs. Lucas: Exactly. And you know, it's episodes like this that remind me why listener support matters. A couple of dollars a month from people who enjoy these deep dives — it genuinely helps keep the research going, the manuscripts translated, the episodes ad-free. It's at buy me a coffee dot com slash fexingo. If you've been following along with us through Mali, it makes a real difference. Luna: Yeah, absolutely. And it's a small way to say thanks for the work that goes into pulling these stories together. Lucas: So where were we? The Star Reader's influence — it didn't end with Mansa Musa. After his death, his son Maghan I inherited the same astrologers, but there's a tragic twist: according to the Tarikh al-Sudan, Maghan ignored their advice about a comet that appeared in 1337, and the ensuing campaign against the Songhai ended in disaster. The jeliw say it was because he 'turned his back on the stars.' Luna: So even in Mali, ignoring the astrologers could cost you an empire. Lucas: Exactly. And that story became a cautionary tale for later Keita rulers. It shows how deeply embedded astrology was in the political culture. It wasn't just a fringe belief — it was state policy. And that's what makes it so important for understanding Mansa Musa's Mali: the emperor who controlled the world's gold also believed his fate was written in the stars.
