Hawaiian large coconut feather Makini. The coconut shell is about 3.5 to 4" wide.
Most people call these Hawaiian warrior helmets but they are really called Makaki'i or Makini. The full size versions were worn by some priests during various ceremonies and also by ocean canoe paddlers. Long ago during a visit by Captain James Cook to Kealekekua Bay on the Big Island of Hawaii, the ship's artist John Weber saw and sketched men paddling canoes wearing gourd masks and feathers. These men were members of a warrior society called makini and were in trusted with the protection of their high chief. Today the warrior helmets can be found on car rear view mirrors and over home doorways not only as decorations but a symbol of safety and protection.
