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.
Cucuteni–Trypillia culture
One such early example of a proto-writing system are the Vinča symbols, which is a set of symbols depicted on clay artefacts associated with the Vinča culture, which flourished along the Danube River in the Pannonian Plain, between 6000 and 4000 BC. The first discovery of this script occurred at the archaeological site in the village of Turdaş (Romania), and consisted of a collection of artefacts that had what appeared to be an unknown system of writing. In 1908, more of these same kinds of artefacts were discovered at a site near Vinča, outside the city of Belgrade, Serbia. Scholars subsequently labelled this the "Vinča script" or "Vinča–Turdaş script". There is a considerable amount of controversy surrounding the Vinča script as to how old it is, as well as whether it should be considered as an actual writing system, an example of proto-writing, or just a collection of meaningful symbols. Indeed, the entire subject regarding every aspect of the Vinča script is fraught with controversy.
