Almost every month now, someone claims to have deciphered the enigmatic script of the Indus Civilisation, the last undeciphered script of any major ancient civilisation. Dozens of scholars have tried in vain to get a grip on it. This does not really surprise, for neither the value of individual signs nor the underlying language(s) are known. To be able to read the more than 4,200 Indus seals and inscriptions would provide major and probably surprising insights into the oldest history of India.
The most recent attempt at decipherment by .S. Rajaram and . Jha in their book The Deciphered Indus Script has just been exposed in Frontline and a discussion has been initiated in The Pioneer. This decipherment is but a collection of wild guesses, based on an incredibly flexible Indus "alphabet" and compounded and bolstered by actual fraud, Rajarams "Piltdown" horse. One Indus seal (Mackay 1937-8, no. 453) is supposed to read, in late Vedic Sanskrit: "Arko haasva, Sun indeed like the horse [sic]," a reference to the Yajurveda! According to Rajaram, it is accompanied by a picture of a horse. But this picture is found on a broken seal, where the front part of the "horse" is missing, and only the hindquarters of a typical "unicorn" bull are visible. The very break line of the seal, fuzzily reproduced from a clear original, is reconstructed by Rajaram as the neck and head of a horse and made "visible" in an added "artists impression".
