Apart from a handful of references in Greek and Latin historical sources, the written history of Greeks of Bactria and Hindus (Indus Valley) is still wanting. This absence of written historical sources is the main obstacle in understanding the nature and scope of their cultural connectivity with the West, particularly Greece and her colonies. This lacuna cannot be filled with the help of Bactrian or Hindusian Greeks’ coinage alone. Archaeological discoveries, when combined with available historical references can answer this waxed question to some extent as well.
