Note 21 — Chapter IX · THE EUPHRATES FRONTIER AND THE PARTHIANS.

Arrian, who, as governor of Cappadocia, had himself wielded command over the Armenians (contra Al. 29), always in the Tactica names the Armenians and Parthians together (4, 3, 44, 1, as respects the heavy cavalry, the mailed κοντοφόροι and the light cavalry, the ἀκροβολισταί or ἱπποτοξόται; 34, 7 as respects the wide hose); and, where he speaks of Hadrian’s introduction of barbaric cavalry into the Roman army, he traces the mounted archers back to the model of “the Parthians or Armenians” (44, 1).
