Moai are the monolithic human stone sculptures of Easter Island. The massive statutes are generally thought to be representations of the deified(神格化された)ancestors of the Rapanui people, who likely produced them between 1250 and 1500 CE. Carved from soft volcanic tufa, the statues range from 10 to 40 feet (3 to 12 meters) high, with some weighing more than 80 tons. Nearly half are still at the main moai quarry(採石場), but hundreds were transported and set on platforms around the island.
