Where Iboga Came From: 26 Versions of One Myth

A Woman, a River, and Twenty-Six Ways to Tell the Same Story

Every Fang Bwitist community tells a version of the same founding myth. A woman named, depending on the branch, Banzioku, Bandjoku, Muma, Akengue, or one of a dozen other names, goes fishing alone in a river, reaches into a hole in the riverbank chasing a catfish, and pulls out human bones instead. The bones belong to her first husband, a Pygmy who fell to his death from a tree while picking fruit. What follows that discovery, across community after community and branch after branch, becomes the founding sacrament of Bwiti itself, complete with a sacrifice, a resurrection in sound, and the origin of the sacred harp that still sits at the center of every ceremony today.

The Italian ethnobotanist Giorgio Samorini collected and compared 26 distinct recorded versions of this myth, known in the literature as the "story of Banzioku," as the third installment of a research series published in the Antrocom Online Journal of Anthropology in 2024. Twenty-three come from published ethnographic sources going back to the 1940s. Three were gathered in Equatorial Guinea. One, previously unpublished before Samorini's paper, he collected himself in December 2022 from a community of the Ndea Kanga branch. Laid side by side, the versions do not just repeat a story. They argue with each other about what every detail means, and the disagreements are where the real information lives.

The Skeleton of the Story

Strip away the variation and a consistent sequence emerges. A Pygmy man dies falling from a tree. His body rots in the branches and his bones fall to the ground, where an animal, usually a crab, carries them to an underwater hole in a riverbank. His widow, following the custom of the levirate, marries one of his brothers. Later, fishing alone, she finds the bones in the hole while chasing a catfish. A genet, a small spotted carnivore, tries to steal the bones; she throws a net at it, and the contact with the net is said to be the origin of the genet's spots, which were previously solid white. Following the animal, she reaches a cave where she hears voices warning of an intruder. The voices belong to the spirits of the dead, who ask if she wants to see them. When she says yes, they point her to a plant: iboga.

After she eats it, and after an insect is placed in her eye to induce temporary blindness or burning tears, a detail that recurs across many versions, her dead husband and other deceased relatives appear to her in a vision. They give her a new, initiatory name. Then they demand an offering. Her new husband, suspicious that she has been disappearing into the forest, follows her and is caught by the spirits, who also force him to eat iboga and see the dead. When the spirits demand payment for this knowledge, every object the husband offers, a knife, a rifle, is rejected. The only acceptable offering turns out to be his wife. She is killed, usually by strangulation or by having her throat cut, and in most versions her body is eaten by the spirits. What remains of her is transformed into the ngombi, the sacred harp that is the central instrument of Bwiti liturgy, and her voice becomes its sound. Her husband returns to the village, builds the first temple, and founds the cult.

Why the Names Keep Changing

Across the 26 versions, the dead Pygmy's name shifts between Etum, Etoumou, Ndondo, Nza Bika, Kambi, and half a dozen others. The widow is called Banzioku, Bandjoku, Muma, Endzona, Akengue, Elamba, Dinjona, depending on which branch is telling the story. Her second husband is Mobay Bay, Bay-Bay, Bazeu-Bazeu, or Tondondo. Samorini's explanation for this instability is not sloppy oral transmission. According to Bwitist belief, an initiate receives a new name, the nkombo, from the spirits of the dead during the great initiatory vision itself. Several versions of the myth make this explicit: the woman's everyday name and her post-vision initiatory name are both given in the text, and one version from the Ndeya na Dissanga branch spells out that the husband's initiatory name, Nzambé Kana, is distinct from the name he carried before. The myth's characters are, in effect, already Bwiti initiates, and the story is partly explaining where the custom of the initiatory name itself comes from.

One detail recurs with pointed irony. In several versions, the female protagonist is called Muma at the start of the story, which happens to be the same word Bwitists use generally for an uninitiated intruder, someone who does not belong at the ceremony. The woman who becomes the founder of the entire visionary tradition starts the story labeled, in the sect's own vocabulary, as someone who has no business being there.

The Pygmy Question, Again

In most of the 26 versions, the central characters are explicitly Pygmies. Only the versions collected from the Ndea Kanga branch shift the ethnic identity of the protagonists to the Mitsogho. Two versions from Equatorial Guinea describe the characters as belonging to the "Bakui tribe," a name some earlier scholars treated as an obscure, otherwise unattested ethnic group. Samorini offers a more plausible reading: the Fang word for Pygmies is nkü, plural bekü, and Beku happens to be the actual name of one Pygmy subgroup living along the Atlantic coast. "Bakui" is most likely a garbled transliteration of the same word, meaning the Equatorial Guinea versions are not introducing a mystery ethnic group at all. They are simply saying Pygmies in a slightly different spelling, which lines up with the broader, near-universal insistence across Fang communities that Bwiti's deepest roots trace back to Pygmy origin, a claim examined in more skeptical detail in our historical overview of the Bwiti tradition.

What the Animals Are Actually Doing

The animal details in the myth are not decoration. One version, collected by Świderski, specifies that the crab carrying the dead man's bones used his skull as a mboumbouiti, a relic normally reserved for the skull of a person who had been a skilled harp player in life, and adds the detail that the crab itself "played the harp" at the time, and that all the animals present were already banzi, initiated Bwitists, before the cult had ever reached humans. In other words, some versions of the myth imply that Bwiti existed among animals before it existed among people, a theme that echoes a separate Mitsogho mythological cycle called Motombi, in which animals play musical instruments at the bottom of a river. Samorini flags this as a hint of deeper, mostly lost beliefs about the involvement of the animal world in the cult's earliest layers, of which only scattered fragments survive.

The genet, mossingui in several local languages, carries specific symbolic weight that several versions develop in different directions. Its spotted coat, acquired in the myth as a direct result of contact with the fishing net, becomes a marker of the world of the dead. In one version, the spirits explicitly tell an initiate that the genet "is this little animal that will walk with him, that will lead him towards me... that will bring the sick person back from me to you," framing the animal as a kind of psychopomp, a guide between the worlds of the living and the dead. A related Tsogho tale reinforces the same association: several animals, including the genet, acquire spots on their skin on the day they touch the corpse of a semi-divine, semi-human figure named Mosodwé, which one researcher, Mary, connects to the blotchy discoloration that actually appears on human skin during the early stages of decomposition, a grim but concrete physiological detail hiding inside what looks like pure folklore.

The Harp Comes From Her Body

The origin of the ngombi, Bwiti's central musical instrument, varies by version but always traces back to the sacrificed woman's body, sometimes directly, sometimes through an intermediate stage. One version from Equatorial Guinea is anatomically explicit: the harp's strings are her intestines, its sound box is the skin of her belly, its tuning pegs are her ribs, the cord used to hang it on the temple wall is the same rope used to strangle her, and the music it produces is understood as her lament. A variant from the Ndeya na Dissanga branch instead has her body buried, with the enzesan tree growing from the burial site, its wood later used to build harps. In a version from the Assumgha Ening branch, a different instrument, the obaka, a stick-and-resonator percussion instrument, is built instead from the bones of the dead Pygmy himself: his spinal column becomes the shaft, his femurs the supports, his forearms the drumsticks.

Several versions add that the intestines of the original dead Pygmy, left hanging in the tree where he died, touched the ground and gave rise to a climbing vine, anzuma, a local relative of vanilla whose aerial roots were used as harp strings before nylon thread, introduced by European traders, replaced them. Every one of these details, read individually, looks like folkloric color. Read together, they describe a myth doing real cultural work: explaining, episode by episode, where every piece of ritual material culture, the harp, its strings, the percussion instrument, actually comes from, anchoring Bwiti's physical objects to its founding sacrifice rather than treating them as separate inventions.

A Mushroom That Does Nothing, and a Detail That Might Be About Menstruation

A number of versions introduce a second plant alongside iboga at the moment of revelation: a mushroom called duna or duma, which the spirits present as the first container or "dish" from which the iboga root scrapings should be eaten. Samorini notes a detail that undercuts the mushroom's apparent importance: as far as is known, it has no psychoactive properties at all. Its role in the myth is purely ceremonial and symbolic, a serving vessel rather than a second source of vision, which is itself an interesting data point about how the myth distinguishes active from supporting elements in its own cosmology.

A more striking detail appears in several versions describing the moment the protagonist kills the catfish she was originally fishing for: its blood is said to flow onto her pubis, and this is presented as the mythic origin of menstruation. In one version she cleans herself afterward with a leaf from the mbèl tree, chosen specifically because its white bark symbolizes semen and its red interior wood symbolizes blood, a tree that, elsewhere in Fang cosmogony, is associated with Biome, the Fang rendering of Eve, and whose wood is also the material from which sacred harps are built. The myth, in other words, routes the origins of fertility, death, music, and the visionary plant itself through the same small cluster of symbolic objects, repeatedly, across unrelated branches that in most cases had no direct contact with each other.

Why a Comparative Reading Matters More Than Any Single Version

Most popular writing about Bwiti picks one version of the Banzioku story, usually the cleanest or most complete one available in English translation, and presents it as the myth, as though Fang Bwiti had a single canonical scripture the way some religions do. Samorini's comparative method treats that approach as a mistake. The myth exists as a living, branch-specific, continuously retold tradition where the variations between tellings are not noise obscuring a true original version. They are themselves the data, showing which elements every Fang Bwitist community treats as load-bearing (the sacrifice, the harp's origin in the woman's body, the role of the genet) and which elements are regional elaboration specific to one branch's own theological emphasis (the precise identity of the Pygmy protagonists, the exact mechanism of menstruation's origin, whether animals were already Bwitists before humans). Reading only one version means mistaking a single community's local emphasis for the whole tradition. Reading all 26 side by side, the way Samorini's paper does, is closer to what the tradition actually is: not a myth, but a family of myths in active conversation with each other, still being told, still being adapted, down to a community in the Gabonese Estuary area that gave Samorini a version nobody outside their branch had ever recorded, in December 2022.
