Orisha, Mami Wata, and the Fantasy Novel Review Rule

A reader meets Èṣù on page forty. He is standing at a crossroads, which is where he usually stands, and the book does not stop to explain him. Somewhere in nearly every fantasy novel review of a book like that one sits a reassuring sentence, and it arrives right on schedule: you don't need to know the mythology to enjoy this. The line is meant kindly. For most readers it is also true. The trouble is what it quietly promises next — that the mythology is scenery, and that the novel and the tradition are the same object seen from two angles.

They are not. Here is the relationship in one sentence: a fantasy novel and the belief system it draws on are related the way a portrait is related to a person — recognisable, often made with real attention, and answerable to an entirely different set of rules. That distinction is worth about three thousand words, because it is the thing the reassurance skips, and because getting it wrong has produced a century of confident nonsense about African religion.

The advice is mostly right, and for a good reason

Start by giving the advice its due, because it earns it more often than sceptics allow.

When Natasha Bowen opens Skin of the Sea with Simidele, a Mami Wata gathering the souls of people thrown from a slave ship, a reader who has never heard the name Yemọja is not locked out. The book tells you what a Mami Wata does in this story, what it costs her, and what she is forbidden. The information you need arrives in the shape of stakes rather than a lecture. That is craft, and it is the same craft that lets a reader who has never opened Hesiod follow a Greek-inflected novel without stumbling.

Tomi Adeyemi's Children of Blood and Bone does something similar with the ten maji clans of Orïsha. The word orisha (oh-REE-shah) is the Yoruba term for the divinities who govern rivers, iron, thunder, the crossroads and much else — but Adeyemi builds a fictional country and a fictional magic system on top of that vocabulary, and the novel teaches its own rules as it goes. Suyi Davies Okungbowa's David Mogo, Godhunter drops orisha into a fractured Lagos and lets the city do the explaining. Namina Forna's The Gilded Ones invents its own empire and its own alaki rather than mapping one real tradition onto a map. None of these books hands you a syllabus.

Accessibility, in other words, is an achievement rather than a dilution. Fantasy has always run on borrowed pantheons, and no reviewer has ever demanded homework before a Norse-flavoured novel. Asking African-inspired fantasy to come with prerequisites, when nothing else in the genre does, would be its own kind of quarantine. So the reassurance in that fantasy novel review is not wrong. It is incomplete in a specific and interesting way.

Èṣù and Legba: two figures fiction keeps welding together

To see where it goes thin, take two names a fantasy reader is likely to meet and likely to conflate.

Èṣù (roughly EH-shoo) belongs to Yoruba tradition, held by the Yoruba people of southwestern Nigeria and parts of Benin. He is an orisha. He stands at crossroads and thresholds, carries messages between people and the divinities, and is spoken to first in ceremony, because nothing else gets through if the way is not opened. He is also, unmistakably, a disruptor: he tests, he trips, he exposes what people would rather keep covered. In one well-known telling he walks a road wearing a cap that is red on one side and white on the other, so that two friends farming on either side of the path fall into a bitter quarrel about the colour of a hat. The point of the story is not mischief for its own sake. It is that certainty is cheap and perspective is not.

Legba belongs to the Fon of Benin, and to the Ewe of Benin, Togo and southeastern Ghana. He is a vodun (voh-DOON) — the Fon word for a divinity, the same word that gives us Vodou and, by a long and ugly route, "voodoo". Legba, too, is the opener of the way, greeted first, stationed at gates and thresholds. In Haitian Vodou he becomes Papa Legba, often pictured as an old man with a stick, keeper of the gate between the living and the lwa.

So are they the same figure? The honest answer is: related, and distinct. Yorubaland and the Fon kingdom of Dahomey were neighbours for centuries — traders, rivals, and at points conquerors of one another along the Bight of Benin. Names, ceremonies and divination practices moved across that border in both directions for generations before the Atlantic trade carried them further. Scholars of the region generally treat Èṣù and Legba as products of that long exchange rather than as one figure with two names, and they disagree about how much is shared inheritance and how much is parallel development within a shared regional grammar of thresholds and openings. Nobody serious claims one is a copy of the other.

Fiction, needing a single trickster at a single gate, tends to weld them into one character and hand him a hat.

Side by side

Read down that table and you can see why the merge happens. Read across it and you can see what the merge costs: two peoples, two languages, two ritual grammars, two histories of movement across the Atlantic, compressed into one convenient archetype.

Where the advice starts to break

1. When the borrowed thing is a practice, not a story

A creation story can be retold. That is what stories are for, and the Yoruba, Fon, Akan and Dogon accounts of how the world began have been retold by their own tellers in different shapes for as long as anyone has been counting. A novelist who reworks one of those is doing something the tradition itself does.

Ifá is a different case. Ifá (ee-FAH) is a Yoruba divination system in active use today, in Nigeria and across the diaspora. A babaláwo (bah-bah-LAH-woh), a trained diviner, casts and reads a configuration that points to one of two hundred and fifty-six odù — chapters of a vast body of memorised verse, each carrying stories, precedents and prescriptions. Learning it takes years. UNESCO listed it as intangible cultural heritage in the mid-2000s, which tells you something about how it is regarded: not as a folk survival but as a living intellectual system.

When a novel converts Ifá into a magic system with tidy rules and dramatic costs, the reader who arrived with no prior knowledge leaves with exactly one account of it — the fictional one. Nothing corrects it. This is the asymmetry the reassurance hides. A reader who needs no background also carries no ballast, and whatever the book supplies becomes, by default, what they know. The same applies to ancestor veneration, practised in enormously varied forms from the Akan of Ghana to the Shona of Zimbabwe, and to Vodun in Benin, where it is a public and official religion with a national holiday, not an underground rumour.

This is not an argument against fiction using any of it. It is an argument that a book which knows the difference between a story it may retell and a practice it is describing is doing something a book that flattens both into "lore" is not.

2. When the shorthand is somebody's old mistake

Some of the shorthand that reaches fantasy is not neutral compression. It is inherited error.

The most consequential example concerns Èṣù directly. Nineteenth-century Yoruba Bible translation — the tradition associated with Samuel Àjàyí Crowther, himself Yoruba, himself formerly enslaved, and the first African Anglican bishop — rendered the biblical Satan as Èṣù. The choice made a certain missionary sense at the time and has been argued about by Yoruba scholars and clergy ever since. Its effect was durable: generations of readers, including Yoruba Christians, met the name first as a synonym for the devil. Èṣù is not a devil. Yoruba tradition has no adversary of that kind in that role. When a fantasy novel gives its crossroads figure a satanic register, it is usually not drawing on Yoruba belief at all; it is drawing on a translator's decision from the 1850s.

The second example is Vodou. What most readers know as "voodoo" — pins, zombie servants, cackling menace — is a twentieth-century American invention with roots in the United States occupation of Haiti and the pulp market that fed on it. Haitian Vodou is a religion with a cosmology, an ethics, a calendar and a priesthood, practised by millions. A novel is free to invent a sinister magic; it is not free to call it Vodou and claim to have drawn on a tradition.

A reviewer can reasonably say a book requires no prior knowledge. A reviewer cannot say the reader arrives empty. The reader arrives full of a century of bad film.

3. When one version becomes the version

Oral traditions vary by region, by lineage, by teller, and by the occasion of telling. Two towns forty miles apart may give an orisha different parents. A verse recited at one initiation may not be the verse recited at another. Versions differ, and the differing is not a defect in the record; it is how the record works.

A novel needs one version. It needs a fixed cosmology, because the plot has to be able to break rules that the reader can feel being broken. So the novelist picks, and the reader — arriving with nothing — takes the pick as the tradition.

The interesting counter-example is Marlon James's Black Leopard, Red Wolf, which builds its whole architecture out of the problem. Its narrator tells a story that other characters keep contradicting, and the book is organised around the impossibility of getting one account. It is also, by common agreement including its admirers', a demanding read. That is the trade, stated plainly: the books that honour variation ask more of you, and the books that ask less of you tend to hand you a canon that no village would recognise as final.

Mami Wata does two jobs, and only one of them is fiction

Mami Wata (MAH-mee WAH-tah) is the clearest case of a figure who exists twice over.

In coastal and riverine communities from Nigeria and Ghana through Cameroon to the Democratic Republic of Congo, Mami Wata is venerated now — in shrines, through dedicated practitioners, with music, colour and offerings, in traditions that vary considerably from one place to the next. She is associated with water, with beauty, with wealth that comes suddenly and with the demands that come attached to it, and in many communities with healing. She is not a folk memory. People maintain relationships with her this week.

Her familiar image has a history worth knowing. The art historian Henry John Drewal traced the widely reproduced picture of Mami Wata — a long-haired woman with a large snake draped across her — to a late nineteenth-century German chromolithograph of a snake charmer, a performer thought to be Samoan, printed for a Hamburg firm and carried into West African ports by traders. The print circulated, was recognised, was absorbed, and became one of the standard visual forms of a spirit already present in local belief. That is not corruption. It is how living religion has always worked: it takes what arrives and makes it mean something.

In fiction, Mami Wata usually arrives as a mermaid. Sometimes beautifully, as in Bowen's hands, where the mermaid frame carries a story about the Middle Passage and about who is owed a burial. But the mermaid does one job — she is a character with a tail and a longing. The venerated Mami Wata does another, in the present tense, for people who are not reading the book.

Where the connection ends

These are the seams a reader should not smooth over.

• A novel's orisha is not an orisha. Adeyemi's Orïsha is an invented country. The orisha of Yoruba tradition are not characters in a fantasy series that happens to have escaped into reality; they are the subject of a religion with a divination corpus, a priesthood, and adherents in Nigeria, Cuba, Brazil, Trinidad and the United States.
• Related does not mean interchangeable. Èṣù and Legba are neighbours in history and cousins in function. They are not one being with two spellings, and treating them so erases the Fon, or erases the Yoruba, depending on which name survives the merge.
• Diaspora traditions are continuations, not degraded copies. Haitian Vodou, Cuban Lucumí, Brazilian Candomblé — these developed under conditions of enslavement, in contact with Catholicism and with Indigenous American practice, and they are complete religions in their own right. They are neither West African tradition preserved in amber nor West African tradition gone wrong. They are what those traditions became in a new place, which is what traditions do.
• Fiction's debt runs one way. The tradition does not need the novel. The novel needs the tradition. That asymmetry is the whole ethical question in miniature.

Names and terms

• Orisha — in Yoruba tradition, a divinity governing a domain of the world; there are many, and lists differ by region.
• Vodun — the Fon and Ewe word for a divinity; also the name of the religion in Benin and Togo.
• Èṣù — Yoruba orisha of crossroads, messages and disruption; addressed first in ceremony.
• Legba — Fon vodun who opens the way; Papa Legba in Haitian Vodou.
• Ifá — the Yoruba divination system, read by a trained babaláwo against a corpus of 256 odù.
• Yemọja — Yoruba orisha associated with waters and motherhood; Yemanjá in Brazil, Yemayá in Cuba.
• Mami Wata — water spirit venerated across coastal West and Central Africa, in many regional forms.
• Anansi — the Akan spider of Ghana, who talks his way into and out of everything; Anancy in Jamaica.
• Vodou — the religion of Haiti; distinct from Beninese Vodun and from the invented "voodoo" of American film.

A more honest version of the rule

The advice, as usually written, is: you don't need to know the mythology to enjoy it.

A more honest version runs longer, which is why nobody puts it in a blurb:

You don't need prior knowledge to enjoy the book. The book needs prior knowledge to be worth enjoying. And what you should look for is not accuracy — fiction owes nobody accuracy — but whether the book knows the difference between a story it is retelling and a practice it is describing.

That difference shows up in small, checkable ways. Does the novel name a people and a place, or does it say "African"? Does it treat the tradition as something living, or as ruins that its characters walk through? When it invents, does it invent openly — a made-up country, a made-up clan — rather than putting fabrications in a real tradition's mouth? Is there an author's note that says what was borrowed and what was built?

A book can pass all of those and still be dull, and a book can fail one and still be extraordinary. But those are answerable questions, which is more than can be said for "is this respectful".

What this piece did not answer

Several things, and it is worth naming them rather than implying the ground is covered.

It did not ask practitioners what they think. Everything here is about how traditions appear in fiction, which is a question about fiction. What babaláwos in Ibadan, Vodun priests in Ouidah, or Mami Wata devotees in the Niger Delta make of these novels is a different piece and needs different reporting.

It did not touch publishing. How much of what reaches the shelf is shaped by editors, cover designers and marketing departments who want the word "African" on the jacket and the specifics off it — that is an industry question, and the authors are not the only people making these decisions.

And it did not resolve whether writers from a tradition, writers from its diaspora, and writers from outside it are working under different obligations. That argument is live among the authors themselves, and it deserves better than a paragraph.

Where to look next: start with the authors' notes and acknowledgements, which are where novelists usually say plainly what they took and from whom, and which most readers skip. For Mami Wata, Henry John Drewal's work is the standard entry point. For Ifá, translated collections of the odù verses exist and read far stranger and better than any magic system built from them. For Vodou, look for Haitian scholars and practitioners writing about their own religion rather than for anything with a drum on the cover. And for the Yoruba and Fon material, university and museum collections in Nigeria, Benin and abroad have put a great deal online, including the objects themselves.

The Akan of Ghana have a word for this kind of going back. Sankofa — from a saying usually given as "it is not taboo to go back and fetch what you forgot." It is carved as a bird with its head turned backwards, holding an egg. Read the novel first, if you like. The fetching can come after.
