The giant statues of Easter Island are called moai. They’re the subject of a Nova/National Geographic special about who those statues might have been moved into place. The technique that islanders used to move them may have involved tugging at ropes tied around the statue and extending out opposite sides. The statues could then be moved by tugging from alternate directions and “walked” the way you might move a heavy object like a refrigerator. The indigenous term for this technique is neke neke, which translates as “walking with no legs.” This is part of a complete episode.
