The theory that there are similarities to the Indus script was suggested by early European scholars such as the archaeologist John Marshall[20] and the Assyriologist Stephen Langdon,.[21] G.R. Hunter in his book The Script of Harappa and Mohenjodaro and Its Connection with Other Scripts (1934) proposed a derivation of the Brahmi alphabets from the Indus Script, the match being considerably higher than that of Aramaic in his estimation.[22] British archaeologist Raymond Allchin stated that there is a powerful argument against the idea that the Brahmi script has Semitic borrowing because the whole structure and conception is quite different.
