Ecology of a Tool

New Guinea, and especially Papua New Guinea, is the last country in the world where ethnologists were able to closely observe, film and photograph the whole manufacturing chaînes opératoires of polished stone felling tools, from quarry extraction to finished tool use. Research on the polished blades of PNG has evolved over the years, following changing philosophies and research agendas. While it is clear that an exceptional sum of information has been gathered, it remains centered on that small part of the Highlands where conditions for field research were more pleasant than elsewhere. This presentation of Irian Jaya axes therefore tackles a topic that remains mostly unexplored. Until now, stone tool research in New Guinea has followed an anthropocentric approach, in which tools are seen more as vectors for social exchanges than as means of acting on the environment.

This monograph takes a different approach. Here, polished stone blades are placed at the center of the world, between, on one side, the transformed natural environment, and, on the other, the social and economic environment. This approach allows for a suggestion of new avenues of inference in archaeology, as well as to test and abandon existing ones. In this volume, the stone blade is considered as a living being, existing in balance within its biotope. This idea is not far removed from the beliefs of Irian Jaya farmers, for whom life animates certain objects of their material culture.

Following a brief presentation of Irian Jaya, the function of polished stone blades in Irian Jaya societies and the distribution of hafting styles is described, defined and studied along with the quarrying zones and the areas of diffusion and use of their production. The different trends in each area of polished blade production and exchanges are also noted. Finally, it concludes with a discussion of the ethnoarchaeological potential of these contemporary observations.
