The Slain God’s Voice

Central Australia · the Top End · New Guinea · the Vaupés · the Bandiagara cliffs · South Kivu

Two wild dogs crept up on a man and tore him to pieces, and as his flesh flew through the air it whirred like a bullroarer. That is not a simile a Warumungu elder would accept. Where the flesh fell, trees grew that held the dead man’s indestructible soul, and from the wood of those trees the men still cut their bullroarers. The instrument is the ancestor’s body; its roar is the ancestor, undestroyed, still crying out. Follow that logic across four more continents and the same structure keeps surfacing: the roarer is a relic of a founding being who was killed and taken apart, and to swing it is to make him speak.

In brief

  • Among the Warumungu of Central Australia, wild dogs dismember the ancestor Murtu-murtu; his flying flesh roars like a bullroarer and becomes the trees the bullroarers are cut from (Spencer & Gillen 1904).
  • The Marind-anim whirl the sasam, which is the severed penis of the giant Sosom become a watersnake — “the serpent’s own voice” (van Baal 1966).
  • Each Dogon bullroarer is a tongue; one is the tongue of Dyongou Sérou, the first ancestor to die and be resurrected as the serpent Great Mask (Dieterlen).
  • Across the Vaupés, the yuruparí instruments are cut from the palm grown out of a burned anaconda’s ashes — “the body of a slain creator-child” (Berezkin).
  • The instrument carries the being’s own proper name — Sosom, aige, imina na, Tembwe, Karwadi — so the object is not a picture of the god but the god present.

Public domain.

A bullroarer, we are used to being told, is the voice of a spirit — it stands for the ancestor the way a bell stands for a church. But read the origin myths closely and a stronger, stranger claim keeps being made: the wood or stone in the swinger’s hand is a physical piece of a founding being who was killed and dismembered. It is not a portrait of the god. It is a fragment of his corpse, kept sounding. On this reading the roar is not a symbol of the ancestor’s presence; it is the ancestor, refusing to have died. The same idea — call it the dema-relic, after the Marind word for the ancestor-gods whose bodies became the world — turns up in Central Australia, the New Guinea south coast, the northwest Amazon, and the cliffs and mountains of Africa, each time told as a matter of fact, not metaphor.

The founder torn apart

Begin with the clearest case, on the Barkly Tableland north of Alice Springs. Baldwin Spencer and Frank Gillen, working among the Warramunga in 1901, set down the origin story of the instrument the Warumungu call murtu-murtu. Two wild dogs travelled south, came upon the man Murtu-murtu, and attacked him, biting out pieces of flesh and flinging them in every direction. Then the decisive detail, which reads like nothing so much as an equation:

“As the flesh flew through the air it made a noise like that of a bullroarer, and wherever it fell on the ground there immediately sprang up a tree called Naiantha (Grevillea sp.).”

— Baldwin Spencer & F. J. Gillen, The Northern Tribes of Central Australia (1904), p. 279

The flesh, in flight, already is a bullroarer-sound. And when the dogs had torn the whole body apart, they ran round and round biting the trees, “in the hope that they would be able to destroy the spirit or munalgi of the man Murtu-murtu, which was evidently in the trees, but they could not do so.” The ancestor’s soul had survived his dismemberment by lodging inside the very wood — and, Spencer and Gillen finish, “now the Warramunga make the tjurunga called murtu-murtu out of the wood of these trees.” Every link is present in one short myth: the founder is killed and scattered; his flesh sounds like the instrument; his indestructible soul passes into the trees; the instruments are cut from those trees. The roarer a Warumungu man swings at initiation is Murtu-murtu’s body, and the roar is his soul that the dogs could not kill.

That the myth is not incidental to the rite is plain from how the rite is staged. The novice, exhausted after a night of ancestral song, hears the murtu-murtu roar behind him and is “too frightened to do anything”; he is circumcised, and only afterward, by firelight, is the marked wooden instrument shown to him for the first time. He then carries it in seclusion through a full turn of the moon, on pain of death should any woman or child see it. The object he guards is the ancestor himself, come back to sound.

A gallery of relics

Once the shape is in the eye, it appears again and again, each culture supplying its own dismemberment and its own relic.

Sosom’s severed member (Marind-anim)

A dark carved wooden bullroarer worked into the shape of a fish, with an incised surface.

On the south coast of New Guinea the Tugeri or Kaya-Kaya and their neighbours the Marind-anim swing an instrument that shares one name with a giant: Sosom. He comes each year with the south-east monsoon, a being of stone so vast he stands with a foot on either bank of the Merauke River, and at his festival the roarers are sounded and the boys are “swallowed” and given back as men. The instrument’s origin is a mutilation. In the telling J. van Baal reconstructed from Marind tradition, the older men — worn out by the boy-giant’s endless roaring — cut off Sosom’s penis; “it fell into the river and became a watersnake — and the bullroarer the men whirl is that severed member, the serpent’s own voice.” Here the relic-logic runs to its limit and fuses three things into one: the severed organ, the snake it becomes, and the whirled blade are a single identity. Nowhere else in the atlas does the full chain of phallus, serpent, and instrument crystallize so completely; the Marind case is the type-site for it.

The penis-tjurunga of Witanygula (Nambutji)

Far to the south, in the northern Western Desert, Géza Róheim collected the same structure without the serpent. The Nambutji bullroarer is the windirpiri, and behind it stands Witanygula — the penis of an old man who sat forever at a place called Kuna-tari. The organ travelled under the earth of its own accord, seeking women, until a woman named Iniwara found it hidden beneath her tomahawk and chopped it to pieces. The chips turned to stone, becoming the tjurunga that are marked underneath with a penis. The carved windirpiri Róheim carried back to Budapest was identified to him as exactly such a penis-tjurunga: a physical object that both is a severed-member relic and is engraved with the member it is. The dismemberment is inscribed on the surviving fragment.

The body of the slain child (yuruparí, the Vaupés)

In the northwest Amazon the sacred sound belongs to the yuruparí or Kuwai cult, whose voices — the great paxiuba-palm flutes and trumpets, and, across the Vaupés, the whirled bullroarer beside them — are barred from women and shown only to initiated men. Those instruments are said to be a body. In the Tatuyo telling catalogued by Yuri Berezkin, initiate boys who broke a food taboo are devoured by the anaconda Pohé-piné; the snake is made to vomit up their bones and is then burned, and from his ashes grows the palm from which the sacred instruments are cut. The paxiuba that becomes the voices is the creature’s own regrown body — “the body of a slain creator-child.” The instrument is again a relic: not carved to resemble the being, but grown from what was left of him after the killing.

The tongue of the first to die (Dogon)

On the Bandiagara cliffs of Mali the Dogon carve three bullroarers before each Sigui, the great rite held once in sixty years, and give them the name of the carved wooden serpent that is the Great Mask of the Awa society: imina na. On the level of myth, Germaine Dieterlen recorded, each roarer is a tongue — one the Fox’s, cut at the same moment as his larynx; one the catfish’s, symbol of the human fetus; and the third the tongue of Dyongou Sérou, “the first ancestor to die, sacrificed to make human life on Earth possible and then resurrected as the serpent the Great Mask depicts.” The bullroarer is the organ of speech of the being who first met death and came back as a snake — and it is that organ that gives voice, at the climax of the dama funeral, when the Great Mask receives the dead man’s soul. The instrument is a relic of the resurrection it enacts.

The corpse-maker becomes the god (Bembe)

In the mountains above Lake Tanganyika the relic is not an object cut from a body but a man momentarily made into the god. The Bembe bullroarer is Tembwe, a deity who speaks with a leopard’s snarl; and Tembwe rules the circumcision, the rite called Etomba — “the corpse” — by which, in Gossiaux’s account, boys are killed and reforged into men. The circumciser who “kills” and “swallows” the initiate with his adze “becomes Tembwe himself, the leopard who literally creates man.” The slain-and-remade structure has folded in on itself: the operator of the death becomes the roarer-god, and the boy passes through the corpse to be born. “Whoever would surpass Tembwe,” the god-rhombe proclaims at his appearances, “will die crushed in the bush.”

Across all five, the killing is never merely the past of the instrument — it is the mechanism of the present rite. The being is dismembered in illo tempore; the boys are dismembered now. At Murinbata in the Top End the novices are told they will be swallowed alive by Karwadi and vomited up, as the children in myth were cut living from the belly of Mutjingga, the Old Woman who swallowed them. Among the Yolngu of Arnhem Land the men themselves become the great python Yurlunggur, “swallow” the boys, and weeks later hand them back, “regurgitated as grown men.” The roarer is the sound of that digestion — the god’s body eating the boy so the man can be produced.

The signature: the god’s own name

There is a small linguistic fact underneath all of this that turns the relic from an interpretation into a claim the cultures make out loud. The instrument does not carry a generic label — “spirit-voice,” “the bush-being.” Over and over it carries the founding being’s own proper name, so that the object and the god are one word. You do not tell a boy “this stands for Sosom”; you tell him “this is Sosom.”

The Bororo case is a pure specimen of the naming device. The bullroarer is the aige, a fabulous water-monster on the bed of a lagoon; it sounds only at funerals, and when the buzzing begins the women flee into the forest, for to glimpse the aige would mean death. At the climax naked young men, smeared head to foot in clay, crawl on all fours as the beast, and the little board that “is” the aige is shown to the boys for the first time. Among the Yei-nan of the Upper Maro the naming becomes an origin: all the ancestor-spirits once lived inside a giant orei tree, and when it was chopped open each took away a chip that became a kupör, a bullroarer — the token of his authority. The wood is the being’s dwelling made portable. To hold the named object is to hold the presence, which is precisely why the revelation is guarded on pain of death: what is dangerous is not a secret sound but a god in the hand.

The roar is not a symbol of the ancestor’s presence. It is the ancestor, refusing to have died.

The Greek exception

The pattern is sharp enough that it is worth finding where it fails — and the classical Mediterranean supplies the clean counter-case. The Greek bullroarer, the rhombos, also lives inside a dismemberment myth, the greatest one Greece told. In the Orphic story of Zagreus, the infant Dionysus is lured by the Titans with a set of toys — a top, a mirror, knucklebones, and among them the whirled rhombos — and while he is distracted by them the Titans fall on him and tear him to pieces. Andrew Lang, who first drew the Greek object into comparison with the Australian one in 1884, and Jane Harrison after him, both placed the rhombos among these Orphic playthings.

But notice where in the story it sits. The rhombos is the lure the Titans use before the dismemberment — the bait that draws the god to his death — not a relic cut from his body after. It is the instrument of the killing, not a fragment of the killed. Everywhere else in this essay the roarer stands at the far end of the same story: it is what is left of the god once the tearing is done, the piece that keeps him sounding. The Greek instrument occupies the opposite pole of an identical narrative shape. That the two ends should be filled by the same rare object — a small board whirled on a cord to make a roar — is itself the thing to stare at: from Merauke to the Orphic mysteries, the bullroarer is bound to the dismemberment of a divine being, whether as the hook that kills him or the relic that survives him.

Resurrection technology

Set the cases side by side and the generalization is hard to resist. The Warramunga cut their roarers from the trees that hold Murtu-murtu’s soul; the Marind whirl Sosom’s severed member; the Nambutji keep the chopped penis of Witanygula as stone; the Vaupés peoples cut theirs from the palm grown out of the burned anaconda; the Dogon sound the tongue of the first man to die; the Bembe turn the circumciser into the leopard-god. In each the founding being is killed and taken apart, and a piece of him is kept — and kept sounding. This is more than the familiar observation that the roarer is “the voice of a spirit.” A voice can belong to a living thing anywhere. These voices belong to the dead, and specifically to the dismembered dead, and they issue from a surviving fragment of the very body that was torn apart.

Which is what makes the instrument, in the end, a piece of resurrection technology. The god is dead; his body was scattered; and the cult keeps the fragment that will not stop speaking. When the men whirl it, they are not remembering the founder — they are producing him, making the slain being audible in the here and now, and then feeding the boys of each new generation through that sound to be unmade and remade in his image. The dogs bit the trees and could not kill the soul in the wood. That failure is the whole doctrine. The bullroarer is the proof that the founder’s voice outlived his dismemberment; sounding it is the act of raising him again.

The individual myths are each documented in the sources above. The reading that unifies them — that the bullroarer is consistently a corporeal relic of the dismembered founder, so that sounding it is a resurrection — is, as far as we know, original to this page. Ad. E. Jensen’s dema-deity frame develops the case for food-crops (Hainuwele’s body becoming the tubers); the extension to the sounding-instrument, though Sosom sits at the foundation of his own Marind material, appears unstated. It is offered here as a synthesis, not a citation.
