Indus script in the context of "List of Indus Valley civilisation sites"

Many undeciphered writing systems exist today; most date back several thousand years, although some more modern examples do exist. The term "writing systems" is used here loosely to refer to groups of glyphs which appear to have representational symbolic meaning, but which may include "systems" that are largely artistic in nature and are thus not examples of actual writing.

The difficulty in deciphering these systems can arise from a lack of known language descendants or from the languages being entirely isolated, from insufficient examples of text having been found and even (such as in the case of Vinča) from the question of whether the symbols actually constitute a writing system at all. Some researchers have claimed to be able to decipher certain writing systems, such as those of Epi-Olmec, Phaistos and Indus texts; but to date, these claims have not been widely accepted within the scientific community, or confirmed by independent researchers, for the writing systems listed here (unless otherwise specified).

The Harappan language, also known as the Indus language, is the unknown language or languages of the Bronze Age (c. 3300 to 1300 BC) Harappan civilization (Indus Valley civilization, or IVC). The Harappan script is yet undeciphered, indeed it has not even been demonstrated to be a writing system, and therefore the language remains unknown. The language being yet unattested in readable contemporary sources, hypotheses regarding its nature are based on possible loanwords, the substratum in Vedic Sanskrit, and some terms recorded in Sumerian cuneiform (such as Meluhha), in conjunction with analyses of the Harappan script.

There are some possible loanwords from the language of the Indus Valley civilization. Meluḫḫa or Melukhkha (Sumerian: 𒈨𒈛𒄩𒆠 Me-luḫ-ḫa) is the Sumerian name of a prominent trading partner of Sumer during the Middle Bronze Age. Its identification remains an open question, but most scholars associate it with the Indus Valley Civilisation. Asko Parpola identifies Proto-Dravidians with the Harappan Culture and the Meluhhan people mentioned in Sumerian records. In his book Deciphering the Indus Script, Parpola states that the Brahui people of Pakistan are remnants of the Harappan culture. According to him, the word "Meluhha" derives from the Dravidian words mel ("elevated") and akam ("place"). Parpola also relates Meluhha with Balochistan, which he calls the "Proto-Dravidian homeland". He also relates Meluhha with the transient word Mleccha, a Vedic word used to mean "barbarian" and used by the incoming Aryan speaking population for the native Harappan population.

The earliest deciphered epigraphy found in the Indian subcontinent are the Edicts of Ashoka of the 3rd century BCE, in the Brahmi script.

If epigraphy of proto-writing is included, undeciphered markings with symbol systems that may or may not contain linguistic information, there is substantially older epigraphy in the Indus script, which dates back to the mid 4th millennium BCE. Two other important archeological classes of symbols are found from the 1st millennium BCE, Megalithic graffiti symbols and symbols on punch-marked coins, though most scholars do not consider these to constitute fully linguistic scripts, and their semiotic functions are not well understood.

Asko Heikki Siegfried Parpola (born 12 July 1941, in Forssa) is a Finnish Indologist, current professor emeritus of Indology at the University of Helsinki. He specializes in the Indus Valley Civilization, specifically the study of the Indus script.
