Tikopia is a Polynesian outlier now included in the Solomon Islands and Raymond Firth became the champion of the remote island after his field studies in 1928/9. However, as befitted a pupil of Malinowski, he was more interested in kinship systems, land tenure and mortuary rituals than in recording the minutae of material culture in his numerous publications. However he does illustrate a bowl with similarly serrated ridges as those on the present headrest (1970, opp. p. 225). The Michael C. Rockefeller Collection at the Metropolitan Museum of Art, includes a coconut grater of almost identical form, (1979.206.1490) with one lashed forked foot and a single foot carved in the same piece of wood as the narrow seat.
