ABSTRACT
It is to Chinese sources that we must turn for an account of the tribes which overthrew Græco-Bactrian rule, and were a constant thorn in the side of the Parthian Empire. These sources, with faint sidelights thrown on an obscure period by allusions to be found in classic authors, enable us to bridge a gap of several centuries replete with events which exercised a lasting influence on the history of Central Asia.
