What it is

System of some 400 signs on steatite seals, pottery and tablets, with very short texts (average of 5 signs), still undeciphered. Whether a full script or a proto-writing notation, it marked goods and property in a trade network that reached Mesopotamia (Meluhha).

Farmer, Sproat and Witzel (2004) argue it is not a linguistic script but a symbol system; most Indologists consider it writing, perhaps of a Dravidian language. Very probably an independent invention, with possible Mesopotamian stimulus.

What it led to

  • Sealing and labelling of goods for long-distance trade with the Gulf and Mesopotamia
  • Administrative identity of merchants and clans in a civilisation with no evident palaces
  • Its loss without descendants after 1900 BCE left South Asia without writing until Brahmi (c. 300 BCE)
