Writing
The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age of the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BC with earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion.
History of writing
Of several pre-Columbian scripts in Mesoamerica, the one that appears to have been best developed, and has been fully deciphered, is the Maya script. The earliest inscriptions which are identifiably Maya date to the 3rd century BC, and writing was in continuous use until shortly after the arrival of the Spanish conquistadores in the 16th century AD. Maya writing used logograms complemented by a set of syllabic glyphs: a combination somewhat similar to modern Japanese writing.
