Rongorongo: The Script Cut Off From the Knowledge Behind the Moai

In 1864, missionary Eugène Eyraud saw wooden boards covered in unfamiliar signs on Rapa Nui. Only two years earlier, Peruvian slave raiders had carried away many islanders; disease and the collapse of ceremonial life followed. By 1877, the recorded population was only 111. The people able to read Rongorongo, Rapa Nui's carved sign system, were gone before they could explain what the boards said.

The same island still holds about 900 moai, more than 300 ahu platforms, quarries, transport roads, and traces of cultivation. The Rapa Nui organised large work across generations, then lost the people who could have recorded how their society worked. This is not only an undeciphered script. It is knowledge taken from the people who made it, leaving museums and outsiders to finish the story.
