A curious tale is told as to the death of Isdigerd. He was still in the full vigor of manhood when one day a horse of rare beauty, without bridle or caparison, came of its own accord and stopped before the gate of his palace. The news was told to the king, who gave orders that the strange steed should be saddled and bridled, and prepared to mount it. But the animal reared and kicked, and would not allow any one to come near, till the king himself approached, when the creature totally changed its mood, appeared gentle and docile, stood perfectly still, and allowed both saddle and bridle to be put on. The crupper, however, needed some arrangement, and Isdigerd in full confidence proceeded to complete his task, when suddenly the horse lashed out with one of his hind legs, and dealt the unfortunate prince a blow which killed him on the spot. The animal then set off at speed, disembarrassed itself of its accoutrements, and galloping away was never seen any more. The modern historian of Persia compresses the tale into a single phrase, and tells us that "Isdigerd died from the kick of a horse:" but the Persians of the time regarded the occurrence as an answer to their prayers, and saw in the wild steed an angel sent by God.

It would seem that at the death of Isdigerd there was some difficulty as to the succession. Varahran, whom he had designated as his heir, appears to have been absent from the capital at the time; while another son, Sapor, who had held the Armenian throne from A.D. 414 to 418, was present at the seat of government, and bent on pushing his claims. Varahran, if we may believe the Oriental writers, who are here unanimous, had been educated among the Arab tribes dependent on Persia, who now occupied the greater portion of Mesopotamia. His training had made him an Arab rather than a Persian; and he was believed to have inherited the violence, the pride, and the cruelty of his father. His countrymen were therefore resolved that they would not allow him to be king. Neither were they inclined to admit the claims of Sapor, whose government of Armenia had not been particularly successful, and whose recent desertion of his proper post for the advancement of his own private interests was a crime against his country which deserved punishment rather than reward. Armenia had actually revolted as soon as he quitted it, had driven out the Persian garrison, and was a prey to rapine and disorder. We cannot be surprised that, under these circumstances, Sapor's machinations and hopes were abruptly terminated, soon after his father's demise, by his own murder. The nobles and chief Magi took affairs into their own hands. Instead of sending for Varahran, or awaiting his arrival, they selected for king a descendant of Artaxerxes I. only remotely related to Isdigerd--a prince of the name of Chosroes--and formally placed him upon the throne. But Varahran was not willing to cede his rights. Having persuaded the Arabs to embrace his cause, he marched upon Ctesiphon at the head of a large force, and by some means or other, most probably by the terror of his arms, prevailed upon Chosroes, the nobles, and the Magi, to submit to him. The people readily acquiesced in the change of masters; Chosroes descended into a private station, and Varahran, son of Isdigerd, became king.
