Symbols of the Indus Valley Civilisation

Indus script

The Indus script, also known as the Harappan script and the Indus Valley script, is a corpus of symbols produced by the Indus Valley Civilisation. Most inscriptions containing these symbols are extremely short, making it difficult to judge whether or not they constituted a writing system used to record the Harappan language/s that is presumed to have been spoken. Despite many attempts, the "script" has not yet been deciphered.
