Rongorongo

Rongorongo (Roŋoroŋo) is a system of glyphs inscribed on wooden objects associated with Rapa Nui, also known as Easter Island. The Australian Museum describes kōhau roŋoroŋo tablets as culturally significant and acknowledges information shared by Rapa Nui knowledge holders. Its account says oral histories and meanings have been passed down through generations, even though researchers have not deciphered the surviving inscriptions. Describing the corpus only through outside scholarly study would therefore omit living Rapa Nui perspectives.

The surviving corpus is exceptionally small. A 2024 study in Scientific Reports describes fewer than 30 inscribed wooden objects; the Australian Museum gives a count of 26 authenticated artefacts. The museum describes glyphs with human and animal forms and reports that the lines are arranged in a reverse boustrophedon pattern, with alternate lines rotated by 180 degrees. The surviving objects are distributed in collections outside Rapa Nui. These details help document the material tradition, but by themselves do not establish a complete decipherment.

The script's origins remain uncertain. In a 2024 study, Silvia Ferrara and colleagues directly radiocarbon-dated four tablets held in Rome: one yielded a secure mid-fifteenth-century date, while the others dated to the nineteenth century. The authors say this result suggests the use of the script could reach back before external influence arrived. It does not settle whether the writing system was independently invented, nor does it date every tablet or determine the meaning of its signs. The paper notes that the tablets ceased to be produced by the late 1860s amid severe disruption to Rapa Nui communities and knowledge transmission.
