Researchers have dated a wooden tablet bearing the mysterious rongorongo script to between 1493 and 1509. This discovery suggests the Rapa Nui people created the complex writing system long before European contact.
Why it matters
The dating provides strong evidence that this unique script potentially emerged on Rapa Nui as an independent invention. It challenges previous assumptions about the origins of the characters found on the island.
Researchers used radiocarbon testing on four wooden tablets, finding the oldest item dates to the 15th century. This artifact includes part of a corpus containing roughly 15,000 characters and 400 distinct glyphs.
The players
Eugene Eyraud
He was a missionary who provided the first recorded description of the wooden tablets in 1864.
The details
The research team analyzed four tablets currently held by a Catholic congregation in Rome to determine their age. While one tablet predates European contact by over 200 years, three others were crafted from trees felled in the 18th or 19th centuries.
Timeline
1493-1509: Wood for the oldest rongorongo tablet was obtained.
1720s: Recorded European arrival occurred on Rapa Nui.
1864: Missionary Eugene Eyraud first described the wooden tablets.
19th century: Europeans first took note of the script.
The Big Picture
This study of the rongorongo script relies on the first recorded European arrival on Rapa Nui in the 1720s as a baseline for determining if the system was an indigenous development. The research results show the script predates this reference point by over two centuries.
Confirming the age of these artifacts allows historians to better understand the development of human communication and independent literacy. This work bridges a significant gap in historical records regarding the ingenuity of ancient island societies.
The takeaway
The existence of this script highlights the independent cultural development of ancient civilizations before global connectivity. Readers can appreciate this history as a testament to the complexity of pre-modern societies.
