The Map That Broke the Arrow

The island is not rare

Follow the dots away from the south. They run through Indonesian Papua, from Kimam and the Yei country; across the northern coast and the Sepik; into the highlands around Kutubu, Sinasina, Kainantu and the Fore; through Madang and Morobe; and out into New Hanover, New Ireland, Bougainville and the other islands to the east. These are not repetitions of one little southern custom. They are named local traditions in many ecological and ceremonial worlds.

The southern coast and the Fly-Gulf country remain important. Nothing on this map asks us to make them disappear. But they are not an isolated beachhead facing Australia, with the rest of New Guinea falling quiet behind them. That was the contrast required by the 1997 inference. It is not the shape of the record now.

There are still thinly documented places, especially in the west. A dot is a reported locality, not a census and not a measure of how intensely any people were surveyed. Yet that qualification strengthens rather than weakens the correction: even the available record is already far too wide to call the instrument rare elsewhere on New Guinea.

One Sahul, many crossings

Australia and New Guinea should not be imagined as two sealed cultural vessels that first touched across a modern international border. For most of the human past they were parts of Sahul, the larger landmass joined before the flooding of Torres Strait. Genomic work finds a deep shared history, later differentiation, and a long northern connection between Papuan and northern Australian populations. It does not turn the two places into one people; it makes their relationship older and more complicated than the tidy image of a southern giver and a northern receiver.

It also supplies a direction that Montagu’s sentence left out. The genomic study behind the well-known account of “successive waves” finds a Holocene expansion within Australia, from the northeast toward the southwest, with only limited accompanying gene flow. The same study finds an older, modest Papuan-related current into northeast Australia. That is not evidence that a bullroarer was carried south from New Guinea. It is evidence that Australia was never simply the southern terminus of the story.

The sea itself carried more than genes. Archaeology and ethnography document voyages, exchange and selective uptake between southern New Guinea, Torres Strait and Cape York. Bows and arrows provide a clear historical case of north-to-south movement into Cape York; other goods and practices travelled in the opposite direction or stopped at the Strait. The region was a field of crossings, not a conveyor belt.

The stories resist a single route

The bullroarer traditions themselves make the same point. Across New Guinea and northern Australia, the instrument can be the voice of a dangerous being and can appear in initiations that stage swallowing, concealment and return. There are also women-first stories, in which men later take control of the sound. Those resemblances make comparison unavoidable. They do not, by themselves, tell us which shore first gave the sound to the other.

When an old source does name a direction, it is often a local one. Paul Wirz wrote that the Marind Sosom ceremonies, bound to bullroarer use, had come from the east and reached their western limit among the Marind. In the other direction across the Strait, the Kiwai account collected by Haddon says that Kiwai men brought the bullroarer from Boigu. Neither story is an origin charter for all of Sahul. Together they show why a single continental arrow is too blunt for a history made from many routes.

The arrow now has a burden

There is a long history of scholars looking north for influences on Cape York: canoes, weapons, smoking pipes, pottery, ritual and myth have all been discussed in that frame. Some of those cases are well documented; others were assumptions inherited from an older, colonial habit of treating New Guinea as the more “advanced” source. Bullroarers were already listed among the hypothetical cases. The modern picture is better: real north–south connections, real two-way exchange, and no licence to make every resemblance travel in one direction.

This leaves a stronger, not a weaker, question. If a future case is made for a Papuan-to-Australian bullroarer movement, it will have to be made from a route that can be followed—dated evidence, a word with a demonstrable borrowing history, or a traceable ceremonial complex—not from an island falsely described as empty beyond its southern shore.

That is what a map full of particular places can do. It cannot award the bullroarer a birthplace. It can make an old origin story answerable. In this case, the Atlas does exactly that: it returns New Guinea to the argument as an island-wide world of voices, and makes the history of the Strait worth asking again.
