While Australian Aboriginal rock art traditions apparently remain little changed from the previous period, the distinctive Manga’asi ceramics of Vanuatu cease to be produced around the end of the twelfth century. Two remarkable megalithic traditions emerge in two different areas of the Pacific. Around 1100, at the eastern edge of Polynesia, the Rapa Nui of Easter Island carve the first of the island’s distinctive colossal stone figures, or moai. Depicting ancestral chiefs, nearly 900 moai are created over the next five centuries. Around 1200, on the Micronesian island of Pohnpei, work begins on the massive megalithic city of Nan Madol, built on a series of artificial islands around an intricate network of canals.
