Easter Island
They called it the Navel of the World, and
for its inhabitants, Easter Island was the only inhabited
scrap of land on an ocean planet. Even their enigmatic
statues encircle the island with their backs to the
sea.
Location: Easter Island, Chile
Latitude: 27° 05', South.
Longitude: 109° 20', West.
Construction: Over 880 statues called Moai
(pronounced 'mo eye') can be found on this isolated island,
located 2,300 miles from the coast of Chile. The statues range
in size from a few feet to over 30 feet, and weigh up to 150
tons. They were built sometime after the island was colonized
in 300 C.E.. Each statue was hewn out of hard volcanic material
from quarries near the Rano Raraku volcano. The statues are
thought to honor their deity Make Make, or represent chieftans
of the two or three tribes that inhabited this
island.
Originally the island was heavily forested for the construction
of statues and campfires, but the rapid growth of the human
population quickly denuded the island. About 250 years ago,
warfare between the two tribes of 'Easter Islanders' led to the
toppling of most of the statues.
Very little is known about the earlier inhabitants whose very
existence was not realized until 1774 when Captain Cook visited
it and gave it its modern name.
Alignments: Although the vast majority of
the Moai are located on the beaches and face inland, the seven
Moai at Ahu Akivi were built around 1460 C.E. and face the
point at which the sun sets during the equinox.
Each measures 14 feet tall and weighs 12 tons. It was restored
in 1960 by archaeologists William Mulloy and Gonzalo
Figueroa.
It is commonly said that the remarkable aspect of Ahu Akivi is
that the Moai also are the only ones that face out to sea,
however from their central location on the island, all
sight-lines are towards the ocean.
Easter Island oral history from the fewer than 700 remaining
natives do not indicate a deep interest in astronomical
knowledge. Hieroglyphic writings have survived that might
fill-in this information, but have yet to be
translated.
