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.
Early Irish literature
Early Irish literature is the oldest vernacular literature in Western Europe. The earliest existing examples of the written Irish language are Ogham inscriptions dating from the 4th century. Extant manuscripts do not go back farther than the 8th century. Two works written by Saint Patrick, his "Confessio" and "Letter to Coroticus" were written in Latin some time in the 5th century, and preserved in the "Book of Armagh".
