Small wooden statue of uncertain religious significance, carved on Easter Island. The figures, thought to represent ancestors who live on in the form of skeletons, are of two types: moai kavakava (male), with a beaklike nose and goatee and occasionally an animal or a human figure incised on the head; and moai paepae (female), which have a flat, relieflike quality and large eyes. They were sometimes used for fertility rites but more often for harvest celebrations, when the first picking of fruits was heaped around them as offerings.

Moai (or mo‘ai) are monolithic human figures carved from rock on the Polynesian island of Rapa Nui (Easter Island) between 1250 and 1500 CE. Nearly half are still at Rano Raraku, the main moai quarry, but hundreds were transported from there and set on stone platforms called Ahu around the island's perimeter. Almost all moai have overly large heads three-fifths the size of their bodies. The moai are chiefly the 'living faces' (aringa ora) of deified ancestors. The statues still gazed inland across their clan lands when Europeans first visited the island, but most would be cast down during later conflicts between clans.
The statues' production and transportation is considered a remarkable intellectual, creative, and physical feat. The tallest moai erected, called Paro, was almost high and weighed 75 tonnes; the heaviest erected was a shorter but squatter moai at Ahu Tongariki, weighing 86 tons; and one unfinished sculpture, if completed, would have been approximately tall with a weight of about 270 tons.
The moai are monolithic statues, their minimalist style related to forms found throughout Polynesia. Moai are carved in relatively flat planes, the faces bearing proud but enigmatic expressions. The over-large heads (a three to five ratio between the head and the body, a sculptural trait which demonstrates the Polynesian belief in the sanctity of the chiefly head) have heavy brows, elongated noses with a distinctive fish-hook shaped curl of the nostrils. The lips protrude in a thin pout. Like the nose, the ears are elongated, and oblong in form. The jaw lines stand out against the truncated neck. The torsos are heavy, and sometimes the clavicles are subtly outlined in stone. The arms are carved in bas relief and rest against the body in various positions, hands and long slender fingers resting along the crests of the hips, meeting at the hami (loincloth), with the thumbs sometimes pointing towards the navel. Generally, the anatomical details of the backs are not detailed, but sometimes bear a ring and girdle motif on the buttocks and lower back. Except for one kneeling moai, the statues do not have legs.
Though moai are whole body statues, they are often described simply as "heads". This is partly because of the disproportionate size of most moai heads, and partly because from the invention of photography until the 1950s the only moai standing on the island were the statues on the slopes of Rano Raraku, many of which are buried to their shoulders. Some of the "heads" at Rano Raraku have been excavated and their bodies seen, and observed to have markings that had been protected from erosion by their burial.
When first carved, the surface of the moai was polished smooth by rubbing with pumice. Unfortunately the easily worked tuff from which most moai were carved is also easily eroded, and today the best place to see the surface detail is on the few moai carved from basalt, or in photographs and other archaeological records of moai surfaces protected by burial.
Those moai that are less eroded typically have designs carved on their backs and posteriors. The Routledge expedition of 1914 established a cultural link between these designs and the island's traditional tattooing, which had been repressed by missionaries half a century earlier. Until modern DNA analysis of the islanders and their ancestors this was a key scientific evidence that the moai had been carved by the Rapa Nui and not by a separate group from South America.
At least some of the moai were painted; Hoa Hakananai'a was decorated with maroon and white paint until 1868 when it was removed from the island.
The statues were carved by the Polynesian colonizers of the island, mostly between circa 1250 CE and 1500 CE. In addition to representing deceased ancestors, the moai, once they were erected on ahu, may also have been regarded as the embodiment of powerful living or former chiefs and important lineage status symbols.
Completed statues were moved to ahu mostly on the coast, then erected, sometimes with red stone cylinders (pukao) on their heads. Moai must have been extremely expensive to craft and transport; not only would the actual carving of each statue require effort and resources, but the finished product was then hauled to its final location and erected.
The quarries in Rano Raraku appear to have been abandoned abruptly, with a litter of stone tools, many completed moai outside the quarry awaiting transport and almost as many incomplete statues still in situ as were installed on ahu. In the nineteenth century this led to conjecture that the island was the remnant of a sunken continent and that most completed moai were under the sea. That idea has long been debunked, and now it is understood that:
The moai were either carved by a distinguished class of professional carvers who were comparable in status to high-ranking members of other Polynesian craft guilds, or alternatively by members of each clan. The oral histories show that the Rano Raraku quarry was subdivided into different territories for each clan.
It is not known exactly how the moai were moved across the island but the process almost certainly required human energy, ropes, and possibly wooden sledges and/or rollers; as well as leveled tracks across the island (the Easter Island roads).
Oral histories recount how various people used divine power to command the statues to walk. The earliest accounts say a king named Tuu Ku Ihu moved them with the help of the god Makemake while later stories tell of a woman who lived alone on the mountain ordering them about at her will. Scholars currently support the theory that the main method was that the moai were "walked" upright (some assume by a rocking process) as laying it prone on a sledge (the method used by the Easter Islanders to move stone in the 1860’s) would have required an estimated 1500 people to move the largest moai that had been successfully erected. In 1998 Jo Anne Van Tilburg suggested less than half that number could do it by placing the sledge on lubricated rollers.
In 1986 Pavel Pavel, Thor Heyerdahl and the Kon Tiki Museum experimented with a five-ton and a nine-ton moai. With a rope around the head of the statue and another around the base, using eight workers for the smaller statue and 16 for the larger, they "walked" the moai forward by swiveling and rocking it from side to side; however, the experiment was ended early due to damage to the statue bases from chipping. Thor Heyerdahl estimated that this method for a 20-ton statue over Easter Island terrain would allow per day. Around the same time archaeologist Charles Love experimented with a 10-ton replica. His first experiment found rocking the statue to walk it was too unstable over more than a few hundred yards. He then found that placing the statue upright on two sled runners atop log rollers, 25 men were able to move the statue in two minutes. In 2003 further research indicated this method could explain the regularly spaced post holes where the statues were moved over rough ground. He suggested the holes contained upright posts either side of the path so that as the statue passed between them they were used as cantilevers for poles to help push the statue up a slope without the requirement of extra people pulling on the ropes and similarly to slow it on the downward slope. The poles could also act as a brake when needed.
No theory has wide acceptance and, on their website, the science program Nova invites the public to send in their own to be reviewed by archaeologist and Director of the Easter Island Statue Project Dr. Jo Anne Van Tilburg.
In 2008, a Finnish tourist chipped a piece off the ear of one moai. The tourist was fined $17,000 in damages and was banned from the island for three years.
The Rapa Nui National Park and the moai are included in the UNESCO world heritage list of 1994, and consequently the 1972 UN convention concerning the protection of the world's cultural and natural heritage.
The EISP (Easter Island Statue Project) is the latest research and documentation project of the moai on Rapa Nui and the artifacts held in museums overseas. The purpose of the project is to understand the figures' original use, context, and meaning, with the results being provided to the Rapa Nui families and the island’s public agencies that are responsible for conservation and preservation of the moai.
