Scharfe adds that the best evidence, is that no script was used or ever known in India, aside from the Persian-dominated Northwest where Aramaic was used, before around 300 BCE because Indian tradition "at every occasion stresses the orality of the cultural and literary heritage",[1] yet Scharfe in the same book admits that "a script has been discovered in the excavations of the Indus Valley Civilization that flourished in the Indus valley and adjacent areas in the third millennium B.C. The number of different signs suggest a syllabic script, but all attempts at decipherment have been unsuccessful so far. Attempts by some Indian scholars to connect this undeciphered script with the Indian scripts in vogue from the third century B.C. onward are total failures."[42]
