Episode notes
Polynesian Navigation Drove Deliberate Settlement
- Polynesian voyagers were highly skilled long-distance navigators who intentionally searched the empty Pacific for new islands using stars and seabirds.
- Jo Anne Van Tilburg explains settlers mounted planned voyages in double-hulled canoes to colonize Rapa Nui around 800–900 AD.
Rano Raraku Quarry Was The Statue Factory
- Most Moai were carved from soft compressed volcanic ash (tufa) at the Rano Raraku quarry, which functioned as both workshop and water source.
- Around 95% of the statues were made there, with coral and obsidian eyes and occasional red stone 'hats'.
How Communities Hauled Moai To Their Platforms
- Teams used palm trunks as rollers, ropes, and up to ~100 men to haul finished Moai from quarry to ahu across rough tracks.
- The final heave could topple then upright a statue, celebrated by cheers when it stood on the platform.
