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.
Dipylon Inscription
The Dipylon inscription is a short text written on an ancient Greek pottery vessel dated to ca. 740 BC. It is famous for being the oldest (or one of the oldest) known samples of the use of the Greek alphabet. The text is scratched on a wine jug (oenochoe), which was found in 1871 and is named after the location where it was found, the ancient Dipylon Cemetery, near the Dipylon Gate on the area of Kerameikos in Athens. The jug is attributed to the Late Geometrical Period (750-700 BC). It is now in the National Archaeological Museum of Athens (inv. 192).
