Recorded history
More complete writing systems were preceded by proto-writing. Early examples are the Jiahu symbols (c. 6600 BCE), Vinča signs (c. 5300 BCE), early Indus script (c. 3500 BCE) and Nsibidi script (c. before 500 CE). There is disagreement concerning exactly when prehistory becomes history, and when proto-writing became "true writing" However, invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BCE. 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 3400–3200 BCE with earliest coherent texts from about 2600 BCE.
Runic inscriptions
An important Proto-Norse inscription was on one of the Golden horns of Gallehus (early 5th century). A total of 133 known inscriptions on bracteates. There are several legible and partly interpretable inscription that date from the 1st half of the 5th century such as a Silver neck ring found near Aalen with "noru" inscribed in runic alphabets on its inner edge. others discoveries were unearthed around Germany, Denmark, Norway, Hungary, Belgium, England and Bosnia.
