Rongorongo, Easter Island's enigmatic script and Oceania's only known pre-twentieth-century writing system, is here comprehensively documented for the first time. The author tells the full history of rongorongo's exciting discovery and the many attempts at a decipherment. Pre-missionary traditions surrounding rongorongo are described from previously unpublished material. Full transcriptions of all the 25 surviving rongorongo inscriptions are provided, along with detailed photographs of nearly every incised artefact. In over six years of full-time research that took the author from St Petersburg to Easter Island, a wholly new picture of the rongorongo phenomenon has emerged. This book is the definitive study of one of the world's most fascinating and eloquent graphic achievements.
