There aren’t many books on Africa’s Mwindo epic, but here they are!
The Mwindo Epic: From the Banyanga (Congo Republic), edited and translated by Daniel Biebuyck and Kahombo C. Mateene, University of California Press, Berkeley and Los Angeles, 1969. (Banyanga means “the Nyanga people.”) This is a translation of the fullest, most complete, and most satisfying version of the epic available to us.
Hero and Chief: Epic Literature from the Banyanga, Zaire Republic, by Daniel P. Biebuyck, University of California Press, Berkeley, Los Angeles, and London, 1978. Translations of several shorter, widely differing versions.
The Magic Flyswatter: A Superhero Tale of Africa, retold by Aaron Shepard, Skyhook Press, Olympia, Washington, 2008. My own retelling. (The full text can be found on my Web site.)
