The generally accepted theory is that these majestic stone statues were built
to honor Polynesian gods and deified ancestors such as chiefs and other figures
important in the island's history. Most of them are attributed to the 14th and
15th centuries, although some were erected as long ago as the 10th Century.
Their function, it is believed, was to look out over a village or gravesite
as a protector. They may also have been status symbols for villages or clans.
The seven at Ahu Akivi each stand about 16 feet high and weigh about 18 tons.
The tallest moai on the island exceed 30 feet. Moai in the range of 12 to 20
feet are common. Even the occasional tiny moai that you come across are at least
6 feet high.
The ahu of Easter Island vary in length - the longest one is 300 feet, while
some that hold one moai are only several feet long. Each ahu has a stone masonry
base that slopes upward to a high terrace upon which the moai rest. Some
terraces are as high as 15 feet above ground level. All are fairly wide - the
bases of the moai that stand upon them measure as much as 10 feet long by 8 or 9
The island's volcanic rock from which they were carved is softer and lighter
than most other rock, but even the smallest moai weighs several tons. Some of
the moai have been estimated to weigh as much as 80 to 90 tons.
Many of the moai - there are hundreds of them - are erected at sites miles
from the quarry at which they were carved. How could so few people move them
even a couple of feet, let alone several miles, and without breaking them?
And once they did move them, how did they erect them? Even today, using
powerful cranes, it would be no simple task.
Theories on how the Moai were moved
Many Rapa Nui people believe that the statues were moved and erected by
'mana' a magical force. Great kings of a long-gone era simply used their mana to
command the moai to move to the distant sites and stand there. Mana is a word
and concept you hear frequently in South Seas lore. The people of Rapa Nui
believed that the moai also possessed mana, which was instilled at the time
their white coral eyes were put in place, and that the moai used their mana to
protect the people of the island. Today none of the moai have genuine coral eyes
- and thus the mana is no more.
The intervention of Extraterrestrials - the most infamous of these writers is
Erich Von Daniken who suggests that a small group of 'intelligent beings' were
stranded there and taught the natives to make 'robot-like' statues. His main
thrust is that the stone from which the statues are made is not found on the
island- a complete fabrication. This links with theories that Easter island was
once part of the lost civilization of Egyptians
ancient or Atlanteans by visited was Lemuria flying machines.
Other theories include - men sliding the moai along on layers of yams and
The generally accepted belief is that they were transported on sledges or log
rollers and then levered erect using piles of stones and long logs.
"Thor Heyerdahl, whose books
Aku-Aku stirred great
interest in Easter Island, conducted an experiment showing that an upright stone
statue could be moved using ropes, tilting and swiveling it along. But the
experiment was conducted on a flat surface for only a short distance, and this
theory, like Heyerdahl's theory that the islands of the South Pacific were
settled from east to west from South America rather than from west to east from
Southeast Asia, is not considered plausible.
All but a few of the moai of Easter Island were carved at Rano Raraku, a
volcanic cone that contains a crater lake. It is an eerie spot. Scattered all
around Rano Raraku are 394 moai in every stage of evolution. Some are fallen - a
common sight around the island - and some appear to have only heads, although
they are really full figures that have been nearly buried by soil over the
centuries. For reasons that remain a mystery, it appears that the workers at
Rano Raraku set down their tools in the middle of a multitude of projects - and
the moai-building abruptly ceased.
Rongo-rongo is the hieroglyphic script of Easter Island. It has remained a
mystery since its discovery. For over a hundred years, controversy has raged
over the meaning and source of these enigmatic characters.
There are only 21 known tablets in existence - scattered in museums and
private collections. Tiny, remarkably regular glyphs, about one centimeter high,
highly stylized and formalized, are carved in shallow grooves running the length
of the tablets. Oral tradition has it that scribes used obsidian flakes or shark
teeth to cut the glyphs and that writing was brought by the first colonists led
by Hotu Matua. Last but not least, of the twenty one surviving tablets three
bear the same text in slightly different "spellings", a fact discovered by three
schoolboys of St Petersburg (then Leningrad), just before World War II.
In 1868 newly converted Easter Islanders send to Tepano Jaussen, Bishop of
Tahiti, as a token of respect, a long twine of human hair, wound around an
ancient piece of wood. Tepano Jaussen examines the gift, and, lifting the twine,
discovers that the small board is covered in hieroglyphs.
The bishop, elated at the discovery, writes to Father Hippolyte Roussel on
Easter Island, exhorting him to gather all the tablets he can and to seek out
natives able to translate them. But only a handful remain of the hundreds of
tablets mentioned by Brother Eyraud only a few years earlier in a report to the
Father Superior of the Congregation of the Sacred Heart.
Some say they were burnt to please the missionaries who saw in them evil
relics of pagan times. Some say they were hidden to save them from destruction.
Which side should we believe? Brother Eyraud had died in 1868 without having
ever mentioned the tablets to anyone else, not even to his friend Father
Zumbohm, who is astounded at the bishop's discovery.
