Hiri: Archaeology of Long-Distance Maritime Trade along the South Coast of Papua New Guinea

In the late 1800s, missionaries and government officials stationed along the south coast of Papua New Guinea began to observe large fleets of indigenous Motu sailing ships coming and going out of present-day Port Moresby. Each year the women of nearby villages manufactured tens of thousands of clay pots to be loaded onto the ships that men built, then sailed with their cargos westward some 400 kilometers. Upon arrival at prearranged destination-villages in distant lands to the west―lands populated by peoples speaking foreign languages―the pots together with the shell valuables were exchanged for hundreds of tons of sago flour. While in those villages, the men dismantled their ships and built them anew, literally from the bottom up, because trees of sufficient size to make large sailing ships did not grow in the landscapes of their home villages. Both the Motu of the Port Moresby region and sago producers of the Gulf of Papua to the west knew of these ventures as hiri.

Through first-hand archaeological research at recipient villages, archaeologists Robert Skelly and Bruno David investigate the origins of this indigenous maritime trade system, from ancient roots in the famed Lapita culture of three thousand years ago up to the present. They offer details from archaeological digs that led them from the first ceramics of the south coast of Papua New Guinea to pottery with unmistakable signs of the ethnographic hiri. Along the south coast of Papua New Guinea, the maritime endeavor that is the hiri is revealed in historical perspective, including stories of its colonial past.
