One of the world's most famous yet least visited archaeological sites, Easter Island is a small, hilly, now treeless island of volcanic origin. Located in the Pacific Ocean at 27 degrees south of the equator, some 2200 miles (3600 kilometers) off the coast of Chile, the island is 63 square miles in size and has extinct volcanoes rising to 1500 feet. In the early 1950s, the Norwegian explorer Thor Heyerdahl (famous for his Kon-Tiki raft voyages across the oceans) popularized the idea that the island, called Rapa Nui by the natives, had been originally settled by advanced societies of Indians from the coast of South America. Extensive archaeological, ethnographic, and linguistic research has conclusively shown this hypothesis to be inaccurate. It is now recognized that the original inhabitants of Easter Island are of Polynesian stock (DNA extracts from skeletons have recently confirmed this), that they most probably came from the Marquesas or Society islands, and that they arrived around AD 380 to 400. At the time of their arrival, the island was entirely covered in thick forests and was teeming with land birds. It was the richest seabird breeding site in Polynesia and probably in the whole Pacific. Within a matter of centuries this profusion of wildlife was entirely destroyed by the islanders' way of life. The reasons are today eminently clear.
It is estimated that the original colonists, who were quite probably lost at sea, arrived in just a few canoes and numbered fewer than 100. Because of the plentiful bird, fish, and plant food sources, the population grew rapidly and gave rise to a rich religious and artistic culture. However, the resource needs of the growing population inevitably outpaced the island's capacity to renew itself ecologically and the ensuing environmental degradation triggered a social and cultural collapse. Pollen records show that the destruction of the forests was well under way by the year 800, just a few centuries after the start of the first settlement. These forest trees were extremely important to the islanders, being used for fuel, for the construction of houses and ocean-fishing canoes, and as rollers for transporting the great stone statues. By the 1400s the forests had been entirely cut, the rich ground cover had eroded away, the springs had dried up, and the vast flocks of birds coming to roost on the island had long since disappeared. With no logs to build canoes for offshore fishing, with depleted bird and wildlife food sources, and with declining crop yields because of the erosion of good soil, the nutritional intake of the people plummeted. First famine, then cannibalism, set in. Because the island could no longer feed the chiefs, bureaucrats, and priests who kept the complex society running, chaos resulted, and by 1700 the population dropped to between one-quarter and one-tenth of its former number. During the mid 1700s rival clans began to topple each other's stone statues. By 1864 the last of the statues was thrown down and desecrated.

Scholars are unable to definitively explain the function and use of the moai statues. It is assumed that their carving and erection derived from an idea rooted in similar practices found elsewhere in Polynesia but which evolved in a unique way on Easter Island. Archaeological and iconographic analysis indicates that the statue cult was based on an ideology of male, lineage-based authority incorporating anthropomorphic symbolism. The statues were thus symbols of authority and power, both religious and political. But they were not only symbols. To the people who erected and used them, they were actual repositories of sacred spirit. All carved objects in ancient Polynesian religions were, when properly fashioned and ritually prepared, believed to be charged by a magical spiritual essence called mana. The ahu platforms of Easter Island were the sanctuaries of the people of Rapa Nui, and the moai statues were the ritually charged sacred objects of those sanctuaries. While the statues have been toppled and re-erected over the centuries, and while great social and environmental calamity afflicted the island, the mana or spiritual presence of Rapa Nui is still strongly present at the ahu sites and atop the sacred volcanoes.
