Indus script

The term Indus script (Harappan script) refers to short strings of symbols associated with the Harappan civilization (Indus Valley Civilization—most of the Indus sites are distributed in present day  Pakistan and North West India) used between 2600–1900 BC. In spite of many attempts at decipherments and claims, it is as yet undeciphered. That the underlying language is unknown and the lack of a bilingual (a "Rosetta stone") makes the decipherments extremely difficult.
