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.
Prehistoric art
Prehistoric artwork such as painted pottery in Neolithic China can be traced back to the Yangshao culture and Longshan culture of the Yellow River valley. During China's Bronze Age, Chinese of the ancient Shang Dynasty and Zhou Dynasty produced multitudes of Chinese ritual bronzes, which are elaborate versions of ordinary vessels and other objects used in rituals of ancestor veneration, decorated with "taotie" motifs and by the late Shang Chinese bronze inscriptions. Discoveries in 1987 in Sanxingdui in central China revealed a previously unknown pre-literate Bronze Age culture whose artefacts included spectacular very large bronze figures (example left), and which appeared culturally very different from the contemporary late Shang, which has always formed part of the account of the continuous tradition of Chinese culture.
