 This discrepancy might be explained by a preservation of late Hellenistic styles for a few centuries in this part of the world.However it is possible that the artifacts actually were produced in the late Hellenistic period.Given the antiquity of these sculptures and a technical refinement indicative of artists fully conversant with all the aspects of Greek sculpture, it has been suggested that Greek communities were directly involved in these realizations, and that "the area might be the cradle of incipient Buddhist sculpture in Indo-Greek style".
