A chief’s four tusks
The Horniman Museum in London holds a boar-tusk ornament from the Mekeo people of Central Province, Papua New Guinea. A. E. Pratt collected it among the Mekeo, and the museum bought it from him in 1905. Its four tusks form two loops, joined by a cane spiral set with seeds and white and blue trade glass beads, and two cuscus tails hang from one loop. The museum dates it to the late 19th century and says such tusk ornaments were important and prestigious: every Mekeo chief inherited two tusk breast ornaments from his father. It adds that the Mekeo told a peace-time chief from a war-time chief, and that war-time chiefs were expected to be fierce and unpredictable.
To verify: A Freiburg city museum record of a Papua New Guinea breast ornament set with boar tusks, said to be worn by men on ceremonial occasions as a sign of rank: its page would not open for us, so it is left out.
