- Lucas: So last time we left off with the Mbira Exile returning to Great Zimbabwe in 1360, and the Council of Song becoming official law. But by 1362, Mambo Chikanda turned his attention to something else entirely — the sky. Luna: He wanted to build an observatory? Lucas: Exactly. Not a telescope — obviously — but a carefully engineered platform on top of the Great Enclosure's outer wall, aligned to track the sun, the moon, and key stars. The vaShona already had deep astronomical knowledge passed down through generations of svikiro, the spirit mediums. But Chikanda wanted to institutionalise it, make it part of the state's ritual authority. Luna: So he's centralising even the stars. Lucas: That's exactly what his opponents said. The mbira followers of Dzivaguru saw the sky as something sacred that should belong to the hills and the svikiro, not to a mambo in a stone palace. But Chikanda pressed ahead. Archaeologists have found what they think is the base of a stone monolith — a gnomon — on the eastern side of the Great Enclosure. It would have cast a shadow at sunrise, marking the solstices. Lucas: The vaShona word for sun is zuva. For moon, mwedzi. For stars, nyeredzi. These weren't just abstract concepts — they were tied to when you plant sorghum, when you hold the Mwari pilgrimage to the Matopo Hills, when the mbira ceremonies should happen. The svikiro had always read those signs from natural rock formations. Chikanda wanted a man-made one. Luna: Was there a specific star they tracked most? Lucas: The Pleiades — called ishwa in some Shona dialects, though we don't know the exact term used at Great Zimbabwe. Its rising in June marked the beginning of the agricultural season. And here's the remarkable part: the conical tower in the Great Enclosure is aligned almost perfectly with the June solstice sunrise. That's not coincidence. The builders had to plan that over decades. Luna: So the tower itself was already an astronomical marker. Lucas: Yes, and Chikanda's new observatory platform would extend that. We have descriptions from Portuguese traders later in the 1500s, talking about how the 'king's astrologers' would climb to a high place to read the sky. But by then, Great Zimbabwe was in decline. The observatory Chikanda built in 1362 was probably the peak of this. Luna: What did Dzivaguru's people do when they heard about it? Lucas: They protested. They said the svikiro alone should interpret the stars, not a mambo who had never fasted in the Matopo caves. There were skirmishes along the Tugwi River. But Chikanda was clever — he invited some of the svikiro to help consecrate the platform. He framed it as a collaboration. Some accepted. Others refused and were exiled again. Lucas: If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. It's what keeps us going episode after episode. Luna: Yeah, and we really appreciate everyone who chips in. It makes a difference. Lucas: Anyway, back to 1362. The observatory platform was finished in the dry season, just before the June solstice. Chikanda himself climbed it at dawn, with the senior svikiro who had stayed loyal. They watched the sun rise exactly over the conical tower. It was a huge political statement — he was aligning himself with the cosmos. Luna: Did it work? Did people accept him as the new sky-reader? Lucas: For a while, yes. But the mbira resistance saw it as blasphemy. They started holding their own sky-watching ceremonies in secret, in the caves of the Zambezi valley, using the old methods. So you had two competing astronomies — one state-sponsored and public, one underground and tied to the hills. That tension would simmer for years. Lucas: And the observatory itself? After Great Zimbabwe was abandoned, the platform crumbled. But the alignment of the conical tower with the solstice sunrise is still visible today. It's one of the most powerful pieces of evidence that Great Zimbabwe was not just a political and economic centre — it was a place where people watched the sky and understood their place under it. Luna: So the stars were part of the power struggle too. Lucas: Absolutely. The stars, the stones, the songs — everything was woven together. And in 1362, Mambo Chikanda tried to weave the stars into his own crown.
