Mesoamerica

The Cascajal Block, a stone slab with 3,000-year-old proto-writing, was discovered in the Mexican state of Veracruz and is an example of the oldest script in the Western Hemisphere, preceding the oldest Zapotec writing by approximately 500 years. It is thought to be Olmec.

Of several pre-Columbian scripts in Mesoamerica, the one that appears to have been best developed, and the only one to be deciphered, is the Maya script. The earliest inscription identified as Maya dates to the 3rd century BC. Maya writing used logograms complemented by a set of syllabic glyphs, somewhat similar in function to modern Japanese writing.
