According to Mayor and Dodson the association of the Dzungarian Gate with gold and griffin ("Protoceratops") skeletons spanned a thousand years of classical history:The second-century A.D. Alexandrian geographer Ptolemy and ancient Chinese sources agree in locating the issedonians along the old trade routes from China to the West, from the western Gobi desert to the Dzungarian (or Junggarian) Gate, the mountain pass between modern Kazakhstan and north-western China. Recent linguistic and archaeological studies confirm that Greek and Roman trade with Saka-Scythian nomads flourished in that region from Aristeas's day to about A.D. 300—exactly the period during which griffins were most prominently featured in Greco-Roman art and literature.
