Although the Indus Valley script is still undeciphered, there is some agreement among a number of leading scholars that it represents some sort of proto-Dravidian language common in South India today. These scholars include the Finnish Sanskritologist Asko Parpola whose Deciphering the Indus Script was published in 1994 but is based on nearly 30 years of computer-aided research, and India's Indus script pioneer and scholar of early Tamil, Iravatham Mahadevan. (Their work will be featured on this site soon.)
