Artabanus II., the Parthian monarch who succeeded Phraates II., appears to have appreciated aright the perils of his position. He was not content, when the particular body of barbarians which had defeated and slain his predecessor, having ravaged Parthia Proper, returned home, to fold his arms and wait until he was again attacked. According to the brief, but expressive words of Justin, he assumed the aggressive, and invaded the country of the Tochari, one of the most powerful of the Scythic tribes, which was now settled in a portion of the region that had, till lately, belonged to the Bactrian kingdom. Artabanus evidently felt that what was needed was to roll back the flood of invasion which had advanced so near to the sacred home of his nation; that the barbarians required to be taught a lesson; that they must at least be made to understand that Parthia was to be respected; or that, if this could not be done, the fate of the Empire was sealed. He therefore, with a gallantry and boldness that we cannot sufficiently admire--a boldness that seemed like rashness, but was in reality prudence--without calculating too closely the immediate chances of battle, led his troops against one of the most forward of the advancing tribes. But fortune, unhappily, was adverse. How the battle was progressing we are not told; but it appears that in the thick of an engagement Artabanus received a wound in the forearm, from the effects of which he died almost immediately. The death of the leader decides in the East, almost to a certainty, the issue of a contest. We cannot doubt that the Parthians, having lost their monarch, were repulsed; that the expedition failed; and that the situation of affairs became once more at least as threatening as it had been before Artabanus made his attempt. Two Parthian monarchs had now fallen within the space of a few years in combat with the aggressive Scyths--two Parthian armies had suffered defeat. Was this to be always so? If it was, then Parthia had only to make up her mind to fall, and, like the great Roman, to let it be her care that she should fall grandly and with dignity. CHAPTER IX. _Accession of Mithridates II.
