Numerals and Phonetic Complements in the Kohau Rongorongo Script of Easter Island

Typological considerations and combinatory properties of the “Crescent” sign suggest that “Crescent” and its multiplied combinations represent numerals in the kohau rongorongo script of Easter Island. Probable phonetic complements for the “Crescent” sign identified by means of the substitution method reinforce this interpretation. As a result, some phonetic readings and an alternative content interpretation of the so-called calendric passage on the Mamari Tablet are proposed.
