Colossal stone figure found on Easter Island carved between c 600-1500 AD. There are 800-1000 known quarried from the volcanic tuff at Rano Raraku. They can be up to 10 meters tall and weigh 28 tons. Many were put in ahu on the coast, on top and facing inland. The moai were probably ancestor figures. Most of the moai were knocked over during internal strife on the island. The term moai also refers to small wooden statue of uncertain religious significance, also carved on Easter Island. The figures are of two types, moai kavakava (male) and moai paepae (female). They were sometimes used for fertility rites but were more often used for harvest celebrations. During the time between these public festivals, the statues were wrapped in bark cloth and kept in private homes.
