They were certainly terminated by a peace in the last-named year--a peace of which it must have been a condition that his late enemies should lend him aid in the struggle which he was about to renew with Rome.

Who these enemies exactly were, and what exact region they inhabited, is doubtful.

They comprised certainly the Chionites and Gelani, probably the Euseni and the Vertse.

The Chionites are thought to have been Hiongnu or Huns; and the Euseni are probably the Usiun, who, as early as B.C.200, are found among the nomadic hordes pressing towards the Oxus.

The Vertse are wholly unknown.
