In the 1990s, scholar Steven Roger Fischer announced a partial breakthrough: reading one surviving tablet, known as the Santiago Staff, as a cosmogonic chant describing sequences of procreation between deities, an interpretation built on matching repeated glyph sequences to repeated grammatical patterns he expected such a chant to contain. The claim drew wide public attention and Fischer's own monograph on rongorongo remains a standard photographic and documentary reference for the script even today. It did not hold up under scrutiny. Linguists Jacques Guy and Igor Pozdniakov demonstrated statistically that the repeating structure Fischer relied on is not a special feature of the Santiago Staff at all, but a generic property of the script itself and of Polynesian chant form more broadly, meaning almost any long enough text built from a limited sign inventory would show similar apparent patterns whether or not Fischer's specific reading was correct. The specialist field has not accepted his decipherment since. What Guy and Pozdniakov's rebuttal leaves behind is not a competing decipherment of its own, but a caution: rongorongo's repetitive internal structure is real and worth studying, but it cannot by itself prove what, if anything, a given sequence of glyphs actually says.
