Statues On Easter Island, How Did They Get There?

Many of the statues on Easter Island not along the coast are in places that featured a resource vital to the communities that lived and worked there.

The statues on Easter Island are among the most mysterious objects made by humans. We still don’t know how they were moved, why they were placed at particular sites around the island, and why they were made in the first place. Now, researchers think they have at least some answers. Because a new analysis finds that the statues on Easter Island are situated near sources of freshwater.

It’s believed that the residents of Rapa Nui—the indigenous name for Easter Island—began constructing these carvings in the 13th century. The statues on Easter Island, called moai, which sit upon stone platforms called ahu, are the very definition of monumental. Most weigh between 20 and 30 tons. And of the thousand on the island, about 400 have been moved from the quarry where they originated and placed on ahu located elsewhere.

“But those ahu locations aren’t necessarily everywhere. They’re in some places and not in others. And the question we started to ask ourselves was, why do we find these ahu and moai some places on the landscape but not others?”

Carl Lipo, an anthropologist at Binghamton University in central New York. He says that most of these sculptures are found along the coast, but some are inland. And they’re not necessarily at obvious places.

“For example, we don’t find ahu and statues on Easter Island located on the tops of hills. Places that we might expect to find them if these things were symbolic or representing ancestors where you wanted to show off to everybody in he world, or the island itself, the fruits of your creation of these statues.”

So the statues on Easter Island are more than just towering talismans to be admired from afar. Indeed, Lipo and his colleagues noted that people spent most of their time living and working around these sites. Which made the researchers think that the the statues might be located near a valuable resource.

“So the question was: what resource, was it water, freshwater, marine resources, or cultivation places? Which of those or which combination of those best explained the locations of ahu on the landscape.”

Their statistical analyses pointed toward potable water, which Lipo says made sense.

“Every single time we found a big source of freshwater, there would be a statue and an ahu. And we saw this over and over and over again. And places where we didn’t find freshwater, we didn’t find statues and ahu.”

Now, that doesn’t mean that the structures served as markers…like a sign saying Get Your Water Here.

But rather that the community themselves were connected to those resources and thus their investment in statues on Easter Island was done around that resource.

“Because these are the locations that had the resources that they needed to survive.”

It seems that many of the massive sculptures are where they are for totally pragmatic reasons: we’ll build here because here is where we want to be.
