OLMECA
It is believed that the Olmecs would have invented the first systems of Mesoamerican writing, calendar and epigraphy, which would then inspire other cultures to come.
There is evidence of prior writing even in the Zapotec language. This writing through glyphs syllabically represents the Olmec language, which would become a mixe-zoque language.
