INVESTIGATE

In 1864, a French missionary walked into houses on Easter Island and found something astonishing: wooden tablets covered in rows of tiny carved figures — birds, fish, turtles, people — each no bigger than a fingernail. It was writing. The only indigenous writing system in all of Polynesia. And there were hundreds of tablets, in nearly every home.

Two years earlier, Peruvian slave raiders had kidnapped half the island's population — including every trained scribe. The knowledge of how to read the script died with them. Today, only 27 objects survive in museums across the world. Not one remains on Easter Island.

Over 20 people have claimed to decode rongorongo. None have been accepted. It remains the most tantalising unread script on Earth.

The Mystery

15,000 Glyphs

Approximately 15,000 legible glyphs survive across 27 objects — tiny carved figures of birds, fish, turtles, and humans, each about 1 centimetre tall. Carved with shark teeth and obsidian into wood from the now-extinct toromiro tree.

Core Glyphs

~52

Statistical analysis reduced 600 catalogued forms to about 52 core glyphs — consistent with a syllabary.

Survivors

27

Of possibly thousands of tablets, only 27 objects survive — in museums across 10+ countries.

Oldest Wood

1493

Radiocarbon dating placed one tablet's wood at 1493-1509 — over 200 years before European contact.

THE GLYPHS

Reverse Boustrophedon

You read one line left to right, then physically flip the entire tablet upside down to read the next line. No other writing system in the world works like this — strong evidence that rongorongo was invented from scratch.

THE TABLETS

Parallel Texts

Three tablets (H, P, and Q) contain nearly identical texts — the "Grand Tradition." This proves the glyphs have fixed meanings and are carefully copied, not random decoration.

THE DATING

Pre-European Origin

2024 radiocarbon dating placed one tablet's wood at 1493-1509 — over 200 years before Europeans reached Easter Island. Evidence that writing was invented independently.

From Invention to Silence

~1493

Oldest Tablet Wood

Radiocarbon dating places the wood of one tablet at 1493-1509 — over 200 years before any European visited Easter Island. The script may be even older.

NOV 1770

Spanish Treaty

Spanish explorers visit Easter Island. Chiefs sign a treaty using marks that some historians think resemble rongorongo — possibly the earliest European witness of the script.

DEC 1862

The Slave Raids

Peruvian slavers kidnap approximately 1,500 people — half the population — including the paramount chief and every trained scribe. The knowledge of how to read rongorongo dies with them.

JAN 1864

Eyraud's Discovery

Brother Eyraud arrives and finds tablets in nearly every house. His letter that December is the first written record of rongorongo — but the scribes are already gone.

1869–74

The Jaussen-Metoro Sessions

Bishop Jaussen works with Metoro Tau'a Ure in Tahiti, recording his chanting over four tablets. Later analysis shows Metoro was likely improvising, not truly reading.

1958

Barthel's Catalogue

Thomas Barthel publishes the first complete catalogue of nearly all rongorongo texts and identifies a lunar calendar on Tablet C — the only part ever convincingly decoded.

Radiocarbon Breakthrough

Silvia Ferrara's team dates tablet wood to 1493-1509, strongly supporting independent invention. New digital scanning and AI analysis continue.

The People in This Story

The Discoverer

Brother Eyraud

French Catholic missionary who arrived on Easter Island in January 1864 and was the first outsider to report the existence of rongorongo tablets. He saw hundreds in nearly every home. He died on the island in 1868.

The Investigator

Bishop Jaussen

Bishop of Tahiti who recognised the tablets' significance in 1868. He collected several tablets and spent years working with Metoro Tau'a Ure, producing the famous "Jaussen List" of glyph meanings.

The Modern Breakthrough

Silvia Ferrara

Italian philologist at the University of Bologna whose 2024 radiocarbon dating study placed tablet wood at 1493-1509 — strong evidence that rongorongo was invented independently, before European contact.

A detective's desk with photographs of rongorongo tablets, maps, and research notes
27 tablets. 15,000 glyphs. Over 20 failed decipherments. 160 years of mystery. The script waits — perfectly preserved, completely unread.

The Question That Remains

The tablets are intact. The glyphs are clear. Every carved bird and fish and human figure is perfectly preserved. But the people who could read them have been gone for over 160 years.

Did the Rapa Nui people independently invent one of the rarest achievements in human history — true writing? Or is rongorongo something else entirely? And will anyone, ever, crack the code?
