malady at the exact moment of the last thunder-clap; a third theory was that his attendants had taken advantage of the general confusion to assassinate him, and that he merely added another to the long list of Roman emperors murdered by those who hoped to profit by their removal. It is not likely that the problem of what really caused the death of Carus will ever be solved. That he died very late in A.D. 283, or within the first fortnight of A.D. 284, is certain; and it is no less certain that his death was most fortunate for Persia, since it brought the war to an end when it had reached a point at which any further reverses would have been disastrous, and gave the Persians a breathing-space during which they might, at least partially, recover from their prostration. Upon the death of Carus, the Romans at once determined on retreat. It was generally believed that the imperial tent had been struck by lightning; and it was concluded that the decision of the gods against the further advance of the invading army had been thereby unmistakably declared. The army considered that it had done enough, and was anxious to return home; the feeble successor of Carus, his son Numerian, if he possessed the will, was at any rate without the power to resist the wishes of the troops; and the result was that the legions quitted the East without further fighting, and without securing, by the conclusion of formal terms of peace, any permanent advantage from their victories. A pause of two years now occurred, during which Varahran had the opportunity of strengthening his position while Rome was occupied by civil wars and distracted between the claims of pretenders. No great use seems, however, to have been made of this interval. When, in A.D. 286, the celebrated Diocletian determined to resume the war with Persia, and, embracing the cause of Tiridates, son of Chosroes, directed his efforts to the establishment of that prince, as a Roman feudatory, on his father’s throne. Varahran found himself once more overmatched, and could offer no effectual resistance. Armenia had now been a province of Persia for the space of twenty-six (or perhaps forty-six) years; but it had in no degree been conciliated or united with the rest of the empire. The people had been distrusted and oppressed; the nobles had been deprived of employment; a heavy tribute had been laid on the land; and a religious revolution had been violently effected. It is not surprising that when Tiridates, supported by a Roman _corps d’armee_, appeared upon the frontiers, the whole population received him with transports of loyalty and joy. All the nobles flocked to his standard, and at once acknowledged him for their king. The people everywhere welcomed him with acclamations. A native prince of the Arsacid dynasty united the suffrages of all; and the nation threw itself with enthusiastic zeal into a struggle which was viewed as a war of independence. It was
