Great development of Bactrian power.

Reigns of Priapatius (Arsaces IV.) and Phraates I.( Arsaces V.)_ Selbucus might perhaps not have accepted his defeat as final had he been altogether free to choose whether he would continue the Parthian war or no.

The resources of his Empire were so vast, his command of men and money so unbounded, that he could easily have replaced one army by another, and so have prolonged the struggle.

But renewed troubles had broken out in the western portion of his dominions, where his brother, Antiochus Hierax, was still in arms against his authority.

Seleucus felt it necessary to turn his attention to this quarter, and having once retired from the Parthian contest, he never afterwards renewed it.
