"At this time Assyria was trading with Cappadocia and importing tin from the east. The source of this tin may have been in central and northern Afghanistan (Kandahar and Badakshan), whence the Harappans and the Bactrians appear also to have obtained their supplies… On the other hand, from the 18th century B.C. onwards, north Syrian seals show such a typically Central Asian motif as the two-humped Bactrian camel, which is depicted in the BMAC seals several times…These cultural contacts between the Syro-Hittite world and the BMAC do not prove that the hypothetical Aryan authors of the BMAC came from the west, as suggested by Sarianidi (1993b, 1994), but rather foreshadow the takeover of power in Syria by the Mitanni Aryans and support their Central Asian origin.”"
