The African Colleagues

A passing commentary by Ibn Mājid last week draws my attention to some aspects of his relation to Africa: “According to the ancients, this mansion (he is referring to Sa‘d al-su‘ūd, mansion 24) is found within the sign of Capricorn, but the people of Zanj (roughly what we know as the Swahili coast) consider that, as of the date of this book, it belongs in Aquarius.”

The intensity and historical importance of the maritime traffic between the west coast of India, the Arabian Peninsula, and the east coast of Africa, has been the subject of much international research, and it has elicited from medieval legends to modern soap operas shared across cultural and national boundaries. This sort of Oceanic triangle, comprising the historical areas of the Arabian Sea and the Sea of Zanj, bears testimony archaeologically, linguistically, religiously, economically and in other domains to perennial cultural exchange. So this is not new, and recent scholarship keeps stretching the historical boundaries of this fascinating record.

A second takeaway from our initial citation is the reference to those Zanji astronomers whom he obviously considered as interlocutors, or who were at least into the details of the overlapping between solar and lunar zodiacs. This amounts to saying they had an interest in both theoretical and practical astronomy, including awareness of precessional shifts. It is an enticing testimony to the collegial relations across the waters, and to the state of astronomical study on the Swahili Coast during the 15th century.

Finally, note the ring of immediacy and adventure when he implies that his book is informed by contemporaneous scientific dialogue between Africa and Arabia, and naturally Persia, Gujarat, Malabar… It makes you wonder to what extent our many new exciting initiatives of Indian Ocean Studies are simply picking up the torch, restarting a tradition of generous exchange which became dormant only a few centuries ago.
