concubine of Caracalla; and Heliogabalus, being thus accredited as the son of that emperor, whose memory was dear to the soldiery, had enjoyed the full benefit of that descent, nor can it be readily explained how he came to lose it.

Here, in fact, we meet with an instance of that dilemma which is so constantly occurring in the history. of the Cæsars. If a prince is by temperament disposed to severity of manners, and naturally seeks to impress his own spirit upon the composition and discipline of the army, we are sure to find that he was cut off in his attempts by private assassination or by public rebellion. On the other hand, if he wallows in sensu. ality, and is careless about all discipline, civil or military, we then find as commonly that he loses the esteem and affections of the army to some rival of severer habits. And in the midst of such oscillations, and with examples of such contradictory interpretation, we cannot wonder that the Roman princes did not oftener take warning by the misfortunes of their predecessors. In the present instance, Alexander, the cousin of Heliogabalus, without intrigues of his own, and simply (as it appears) by the purity and sobriety of his conduct, had alienated the affections of the army from the reigning prince. Either jealousy or prudence had led Heliogabalus to make an attempt upon his rival's life; and this attempt had nearly cost him his

影

own through the mutiny which it caused. In a second uproar, produced by some fresh intrigues of the emperor against his cousin, the soldiers became unmanageable, and they refused to pause until they had massacred Heliogabalus, together with his mother, and raised his cousin Alexander to the throne.

The reforms of this prince, who reigned under the name of Alexander Severus, were extensive and searching; not only in his court, which he purged of all notorious abuses, but throughout the economy of the army. He cashiered, upon one occasion, an entire legion he restored, as far as he was able, the ancient discipline; and, above all, he liberated the provinces from military spoliation. "Let the soldier," said he, "be contented with his pay; and whatever more he wants, let him obtain it by victory from the enemy, not by pillage from his fellow-subject." But whatever might be the value or extent of his reforms in the marching regiments, Alexander could not succeed in binding the prætorian. guards to his yoke. Under the guardianship of his mother Mammæa, the conduct of state affairs had been submitted to a council of sixteen persons, at the head of which stood the celebrated Ulpian. To this minister the prætorians imputed the reforms, and perhaps the whole spirit of reform; for they pursued him with a vengeance which is else hardly to be explained. Many days was Ulpian protected by

the citizens of Rome, until the whole city was threatened with conflagration; he then fled to the palace of the young emperor, who in vain attempted to save him from his pursuers under the shelter of the imperial purple. Ulpian was murdered before his eyes; nor was it found possible to punish the ringleader in this foul conspiracy, until he had been removed by something like treachery to a remote government.

Meantime, a great revolution and change of dynasty had been effected in Parthia; the line of the Arsacidæ was terminated; the Parthian empire was at an end; and the sceptre of Persia was restored under the new race of the Sassanides. Artaxerxes, the first prince of this race, sent an embassy of four hundred select knights, enjoining the Roman emperor to content himself with Europe, and to leave Asia to the Persians. In the event of a refusal, the ambassadors were instructed to offer a defiance to the Roman prince. Upon such an insult, Alexander could not do less, with either safety or dignity, than prepare for war. It is probable, indeed, that, by this expedition, which drew off the minds of the soldiery from brooding upon the reforms which offended them, the life of Alexander was prolonged. But the expedition itself was mismanaged, or was unfortunate. This result, however, does not seem chargeable upon Alexander. All the preparations were admirable on the march, and up to the enemy's

frontier. The invasion it was, which, in a strategic sense, seems to have been ill combined. Three armies were to have entered Persia simultaneously: one of these, which was destined to act on a flank of the general line, entangled itself in the marshy grounds near Babylon, and was cut off by the archery of an enemy whom it could not reach. The other wing, acting upon ground impracticable for the manœuvres of the Persian cavalry, and supported by Chosroes the king of Armenia, gave great trouble to Artaxerxes, and, with adequate support from the other armies, would doubtless have been victorious. But the central army, under the conduct of Alexander in person, discouraged by the destruction of one entire wing, remained stationary in Mesopotamia throughout the summer, and, at the close of the campaign, was withdrawn to Antioch, re, infecta. It has been observed that great mystery hangs over the operations and issue of this short war. Thus much, however, is evident, that nothing but the previous exhaustion of the Persian king saved the Roman armies from signal discomfiture; and even thus there is no ground for claiming a victory (as most historians do) to the Roman arms. Any termination of the Persian war, however, whether glorious or not, was likely to be personally injurious to Alexander, by allowing leisure to the soldiery for recurring to their grievances. Sensible, no doubt, of

this, Alexander was gratified by the occasion which then arose for repressing the hostile movements of the Germans. He led his army off upon this expedition; but their temper was gloomy and threatening; and at length, after reaching the seat of war, at Mentz, an open mutiny broke out under the guidance of Maximin, which terminated in the murder of the emperor and his mother. By Herodian the discontents of the army are referred to the ill management of the Persian campaign, and the unpromising commencement of the new war in Germany. But it seems probable that a dissolute and wicked army, like that of Alexander, had not murmured under the too little, but the too much of military service; not the buying a truce with gold seems to have offended them, but the having led them at all upon an enterprise of danger and hardship.

Maximin succeeded, whose feats of strength, when he first courted the notice of the Emperor Severus, have been described by Gibbon. He was at that period a Thracian peasant; since then he had risen gradually to high offices; but, according to historians, he retained his Thracian brutality to the last. That may have been true; but one remark must be made upon this occasion: Maximin was especially opposed to the senate; and, wherever that was the case, no justice was done to an emperor. Why it was that Maximin would not ask for the confirmation of his election from the
