Indus script

Indus script is a collection of symbols that was used by the Indus Valley Civilization. They were used from about 2.500 BC to about 1.900 BC. Most inscriptions are extremely short. About 400 symbols are known. Scientists do not agree if these symbols were used as a writing system to record a language. So far no bilingual text have been found. An example of a bilinhial text us the Rosetta stone which has the same text in three different languages.
