Easter Island statues, historically generally known as moai on the distant island of Rapa Nui within the South Pacific, are a few of the most spectacular artifacts of historic Polynesian civilization. How the statues had been transported has lengthy remained a conundrum, as a result of they’ll weigh as much as a number of tons but are scattered all through the island. Numerous theories have been proposed, together with that they had been dragged on picket sleds or rolled alongside the bottom, however no supportive proof has backed these claims.
In 2012, a US analysis workforce succeeded in propping up a 4.35-ton reproduction of a moai statue and making it “stroll.” The method, wherein two groups utilizing ropes tugged the statue in reverse instructions to teeter it ahead whereas a 3rd workforce ensured it wouldn’t topple over, challenged the traditional theories that moai had been moved in a horizontal place.
The query then is how a lot effort it will have taken to maneuver a lot bigger moai. “As soon as the moai are in movement, it is under no circumstances tough,” defined Carl Lipo, an anthropologist at Binghamton College.
Lipo and his workforce systematically surveyed 962 moai statues on Easter Island, focusing totally on 62 discovered alongside historic roads. They just lately revealed a paper offering sturdy proof that moai had been transported in an upright place.
The workforce additionally succeeded in shifting an actual reproduction of roadside moai 100 meters in 40 minutes with solely 18 folks, a much more environment friendly outcome than these of earlier experiments.
Researchers show how the Rapa Nui folks could have “walked” moai.

The research found that moai statues positioned alongside Rapa Nui’s roads have widespread traits. The broad D-shaped base and ahead leaning design of the statues optimized the moai for “strolling,” whilst they elevated in dimension. The truth is, moai deserted by the facet of the street had been discovered to have imbalanced facilities of gravity and present indicators of toppling over throughout transport.
This speculation can also be supported by the traditional roads themselves, that are roughly 4.5 meters vast and have barely concave cross-sections. Researchers consider these had been supreme situations to help in stabilizing the moai as they had been walked.
A statistical evaluation of the distribution of moai confirmed 51.6 p.c had been concentrated inside 2 km of the quarry the place they originated, demonstrating an exponential decay sample related to mechanical failure somewhat than deliberate ceremonial placement. It’s doubtless these statues had been broken or fell over throughout transport and left the place they lay.
