" Rongorongo. Rongorongo (/ˈrɒŋɡoʊˈrɒŋɡoʊ/; Rapa Nui: [ˈɾoŋoˈɾoŋo]) is a system of glyphs discovered in the 19th century on Easter Island that appears to be writing or proto-writing.

Numerous attempts at decipherment have been made, none successfully. Although some calendrical and what might prove to be genealogical information has been identified, not even these glyphs can actually be read. If rongorongo does prove to be writing and proves to be an independent invention, it would be one of very few independent inventions of writing in human history.[1] Two dozen wooden objects bearing rongorongo inscriptions, some heavily weathered, burned, or otherwise damaged, were collected in the late 19th century and are now scattered in museums and private collections.

None remain on Easter Island. And 280 , have characteristic protuberances on each side of the head, possibly representing ears or eyes. Etymology and variant names[edit] Rongorongo by Sergei V.

There is just one teensy little problem with these analyses: neither Macri nor Pozdniakov have published their decomposition, so until they do, there is little reason why one should accept their claims to have found a decomposition. Pozdniakov does a little better than Macri. But Pozdniakov would appear to have merely re-discovered Zipf's law (well, not quite since the populations of syllables are too small for the curves to be truly Zipfian). Rongorongo. Rongorongo script and the Rapanui language.

Origin The people of Easter Island were possibly inspired to invent the Rongorongo script after seeing the writing used by the Spanish when they annexed the island in 1770. The Easter Islanders were apparently impressed by the mana or power of the Spaniards' writing. Rongorongo was used until the 1860s, after which knowledge of the script was lost. Nowadays most Easter Islanders write in Spanish using the Latin alphabet though a few try to write their own language, Rapanui, also with the Latin alphabet. Since missionaries started visiting Easter Island in the 1860s, they have taken an interest in the mysterious Rongorongo symbols. Two other scripts were once used on Easter Island: Ta'u and Mama, but little is known about them as very few inscriptions have been found. Notable features.
