The case record
What was reported?
Rongorongo consists of finely carved signs surviving on a small number of wooden objects from Rapa Nui. Its reading and the timing of its invention remain debated.
European observers recorded the tablets in the nineteenth century, after devastating slave raids and introduced disease disrupted Rapanui society and the transmission of knowledge. Many objects subsequently left the island. Their dispersal and the loss of knowledgeable readers are central historical facts, not evidence that the signs lacked meaning.
Sortable date marks early European documentation, not the invention of the Indigenous system or the age of tablet wood.

Evidence in the record
Surviving tablets permit comparison of repeated sequences and carving technique. A 2024 radiocarbon study dated wood from four tablets; one early result may predate European contact, but wood age is not necessarily carving age.
Competing explanations
Official and research context
The radiocarbon study dates sampled wood. It does not by itself date inscription, establish pre-contact carving or decipher the script.
Conventional explanations
The signs may encode language, aid recitation or combine functions. Limited texts and absent bilingual material constrain decipherment. Proposed readings must respect the corpus and Rapanui cultural context rather than impose exotic external authors.
Arguments that remain contested
How the signs were read and whether carving began before contact remain open questions.
