For a period of ten years the war was continued by the Armenian potentate; his capital, Vagharshapat, [201] was filled with the booty of successful raids; and, while the temples of the gods throughout Armenia were adorned with costly offerings, their priests received munificent largesses. His fortunes were assisted by an alliance with the Empire; the reigning Cæsar, Alexander Severus, was alarmed by the rise of the new dynasty, and may have been stung by impertinent messages on the part of Ardashir. A Roman army attacked Persia from the side of Armenia, while two more divisions, one under the leadership of the emperor, assailed other portions of the dominions of the king of kings. [202] If the result of the various engagements may appear ambiguous (231-233), it at least ensured the quiescence of the Persian during several years. Ardashir continued to be harassed by the Armenian ally of the Romans, and resolved to rid himself by any means of his inveterate foe. A Parthian of the blood royal volunteered to execute his desire; he went over with his family as a refugee to the court of Chosroes, who received him with the greatest warmth as a valuable ally. After much pleasant intercourse, when spring came on and the king was preparing to take the field, Anak--for such was his name--bethought himself of the pledge which he had given and of the reward promised by Ardashir. In company with his own brother he succeeded in drawing the king aside, when the two villains despatched him with their swords. The crime was committed at Vagharshapat; the guilty pair fled down the valley, hoping to cross the Araxes at the bridge of Artaxata. But they were cut off by the Armenian horsemen and precipitated into the river. The king, before he expired, gave orders that the family of Anak should forthwith be massacred. Only two little children were rescued from the carnage; one was brought up in Persia, and the other, Gregory, in Greece (A.D. 238). [203]
