Moai i/ˈmoʊ.aɪ/, or Mo‘ai, are monolithic human figures carved by the Rapa Nui people on Easter Island in eastern Polynesia between the years 1250 and 1500 A.D. 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-eighths the size of the whole statue. The moai are chiefly the living faces (aringa ora) of deified ancestors (aringa ora ata tepuna). The statues still gazed inland across their clan lands when Europeans first visited the island in 1722, but all of them had fallen by the latter part of the 19th century.
The production and transportation of the more than 900 statues are considered remarkable creative and physical feats. The tallest moai erected, called Paro, was almost 10 metres (33 ft) high and weighed 82 tons; 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 21 metres (69 ft) tall with a weight of about 270 tons. The moai toppled after European contact when islander traditions radically changed.
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 human figures would be outlined in the rock wall first, then chipped away until only the image was left. The over-large heads (a three-to-five ratio between the head and the trunk, a sculptural trait that demonstrates the Polynesian belief in the sanctity of the chiefly head) have heavy brows and 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 features 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 clearly visible legs.
