The Bété syllabary was created for the Bété language (in Africa) of Ivory Coast in the 1950s by artist Frédéric Bruly Bouabré.
It consists of about 440 pictographic characters, which represent scenes from life and stand for single-syllable words in Bété. Bouabré created it to help Bété people learn to read in their language.
