Wood carving is a common art form in the Cook Islands. Sculpture in stone is much rarer although there are some excellent carvings in basalt by Mike Taveoni. The proximity of islands in the southern group helped produce a homogeneous style of carving but which had special developments in each island. Rarotonga is known for its fisherman's gods and staff-gods, Atiu for its wooden seats, Mitiaro, Mauke and Atiu for mace and slab gods and Mangaia for its ceremonial adzes. Most of the original wood carvings were either spirited away by early European collectors or were burned in large numbers by missionary zealots.
