Mayan languages system developed by the Academia de Lenguas Mayas de Guatemala (ALMG). Orthographies for the languages of Mexico are currently being developed by the Instituto Nacional de Lenguas Indígenas (INALI). The pre-Columbian Maya civilization developed and used an intricate and fully functional writing system, which is the only Mesoamerican script that can be said to be almost fully deciphered. Earlier-established civilizations to the west and north of the Maya homelands that also had scripts recorded in surviving inscriptions include the Zapotec, Olmec, and the Zoque-speaking peoples of the southern Veracruz and western Chiapas area—but their scripts are as yet largely undeciphered.
Olmec alternative origin speculations Clyde Ahmad Winters have identified the Olmecs with the Mandé people of West Africa. Some researchers claim that the Mesoamerican writing systems are related to African scripts. In the early 19th century, Constantine Samuel Rafinesque proposed that the Maya inscriptions were probably related to the Libyco-Berber writing of Africa. Leo Wiener and others claim that various Olmec and Epi-Olmec symbols are similar to those found in the Vai script (a relatively modern script in Liberia which may have Cherokee influence), in particular, the symbols on the Tuxtla Statuette, Teo Mask, Cascajal Block, and the celts in Offering 4 at La
