Ngaꞌara was the last great ꞌariki, or paramount chief, of Easter Island, and the last master of rongorongo, the Easter Island script. Before becoming king, Ngaꞌara ran a hare rongorongo at ꞌAnakena Bay. Generally fathers would teach their sons and any other boys who were interested, and Ngaꞌara was the most famous teacher on the island. Boys would study three to five months to learn rongorongo. At the time he became ꞌariki, the real power on the island lay in the Birdman priests of ꞌOrongo. One of the sacred responsibilities of the tuhunga tā seems to have been the recitation or chanting of rongorongo tablets at ꞌOrongo during the annual Birdman ceremonies. That quarter of the village was off limits to everyone else during the ceremonies. Ngaꞌara sent students, but did not himself attend. Rongorongo was considered to contain mana. For example, chanting a timo tablet could release supernatural powers to kill a murderer. A woman would carry a pure tablet while the scribes chanted it to increase her fertility. Tablets were used to increase crops or a catch of fish. Katherine Routledge was told that one of Ngaꞌara's tablets, called Kouhau ꞌo te Ranga and thought to be Rongorongo text C, was one of a kind and had the power to "give conquest in war" and enslave the conquered. In order to take control of the island from the Birdman priests of ꞌOrongo, Ngaꞌara established an annual rongorongo festival at ꞌAnakena. Rather than using the tablets for specific ends, it was a festival for the tablets themselves, and it became the most important assembly in pre-missionary times: Hundreds attended these festivals. Heuheu staves were brought by all and stuck in the ground where the attendee stood. The tablets were recited from dawn to dusk, with a break for dinner. Ngaꞌara presented the reciters with veritapacloths. Since the mana of the tablets went through him at this festival, Ngaꞌara was able to assert spiritual primacy over the island. When Ngaꞌara died, his son Kai Makoꞌi ꞌIti took over the festival at ꞌAnakena for three years, until he was captured in the great Peruvian slaving raid of 1862. Although the slaves were freed the next year, Kai Makoꞌi did not survive to return.
