The sacred stone from the sea. Archaeological and ethnographic perspectives on the ritual value of coral across the Pacific

Abstract

The Pacific Islands offer a variety of marine environments providing peoples in the present and past with abundant coral materials, a “stone from the sea”. Archaeologists have long recognised the importance of coral in ancient contexts, whether as gravel, natural branches, squared blocks or cut-and-dress slabs. Coral was also used to manufacture tools such as files or pounders and incorporated in monumental ceremonial architecture as a favoured construction material and foundation offerings. However, Pacific Islanders also employed coral material for other ritual applications that remain overlooked in the literature. In this article, we consider the multiple uses of coral in the archaeological and ethnographic records of three Pacific regions: Central-East Polynesia (CEP), New Caledonia and the Torres Strait Islands. This includes offering of coral branches, sometimes associated with cairns, paraphernalia and magic stones, also production of coral lime for body ornamentation. Using these case studies, we consider material selection, modes of deposition, archaeological and ethnographic contexts, associations with other features and artefacts, before interrogating the potential significance of these unrealised datasets. By doing so, we shed new light on the ritual value of coral and reflect on the symbolic nature and function of this material.
