When the news of the murder of the emperor was divulged, Macrinus was the first to hasten to the spot, and to deplore his death. As Caracalla had left no heir, the army was uncertain whom to proclaim emperor in his stead, and the empire was for four days without a chief. Meantime the officers who were in the interests of Macrinus used all their influence with their men, and on the fourth day he was saluted emperor. He accepted the office with feigned reluctance, and he distributed, according to custom, large sums of money among the soldiers. Adventus was the bearer of the ashes of Caracalla to Rome, where they were deposited in the tomb of the Antonines; and Macrinus and the senate were obliged to yield to the instances of the soldiers, and place the monster among the gods. The senate received with joy the letter in which Macrinus announced his elevation to the empire, and they decreed him all the usual titles and honours.
While these changes were taking place in the Roman Empire, Artabanus had passed the Tigris with a large army. Macrinus having in vain proposed terms of accommodation, led out his legions, and some fighting took place in the neighbourhood of Nisibis, in which the advantage was on the side of the Parthians; but as they now began to feel the want of supplies, and were anxious to return home, they readily listened to the renewed proposals of the Roman emperor, and a peace was concluded. Macrinus then led his troops back to Antioch for the winter.
Roman General
(From a vase)
Macrinus, as we have already observed, was not a military man. He was a native of Cæsarea in Africa (Algiers), of humble origin, and he was indebted for his elevation to his countryman Plautianus. He was a man of an amiable disposition, and a sincere lover of justice. He therefore turned his attention chiefly to civil regulations, and he made some necessary reforms and excellent laws; but he was timid by nature, and in his anxiety to serve and advance his friends, he did not sufficiently consider their fitness for the employments which he bestowed on them. He committed a great and irreparable fault in not setting out for Rome at once, and in keeping the army all together in Syria; and he further commenced too soon a necessary, but imprudent attempt at bringing back the discipline of the legions to what it had been under Severus; for though he applied it only to recruits and did not interfere with the old soldiers, these last apprehended that the reform would at length reach themselves, and they became highly discontented. This feeling of the soldiers was soon taken advantage of, and a rival set up to Macrinus.
The empress Julia was at Antioch at the time of the murder of Caracalla. Macrinus wrote to her in very obliging terms; but in the first transports of her grief at the death of her son or the loss of her power, she had given herself several blows on the breast, and thus irritated a cancer with which she was afflicted, and her death ensued. Her sister, named Mæsa, who had lived at court during the last two reigns and had acquired immense wealth, retired by order of Macrinus to her native town of Emesa. She had two daughters named Soæmias and Mamæa, each of whom was a widow with an only son; that of the former was named Bassianus; he was now a handsome youth of seventeen years of age, and the influence of his family had procured for him the lucrative priesthood of the Sun, who was worshipped at Emesa under the title of Elagabalus. The Roman troops who were encamped near the town used to frequent the temple, and they greatly admired the comely young priest, whom they knew to be a cousin of their lamented Caracalla. The artful Mæsa resolved to take advantage of that feeling, and she made no scruple to sacrifice the reputation of her daughters to the hopes of empire: she therefore declared (what was perhaps true) that Caracalla used to cohabit with her daughters in the palace, and that Bassianus was in reality his son. Her assertion, backed with large sums of money and lavish promises of more, found easy acceptance with the soldiers. On the night of the 15th of May, 218, she and her daughter and grandson, and the rest of her family, conducted by their eunuch Gannys, a man of great talent, stole out of the city and proceeded to the camp, where they were joyfully received; and Bassianus was proclaimed emperor by the title of M. Aurelius Antoninus. The camp was immediately put into a state of defence against a siege; and numbers of the other soldiers hastened to sustain the cause of the son of Caracalla.
Macrinus sent the prætorian prefect Ulpius Julianus against the rebels. This officer was successful in his first attack on their camp; but having neglected to push his advantage, he gave the enemy time for tampering with his troops, a part of whom abandoned him; and he was taken and slain. Macrinus had meantime advanced as far as Apamea, where he declared his son Diadumenianus, a boy of only ten years of age, Augustus, and took this opportunity of promising a large gratuity to the army; he also wrote against Bassianus to the senate and governors of provinces. But instead of advancing rapidly against the rebels, he fell back to Antioch, whither they speedily followed him, and he was forced to give them battle near that town. The troops of Bassianus were ably disposed by the eunuch Gannys, who now in arms for the first time in his life showed the talents of a general. But the prætorians on the side of Macrinus fought with such determined valour that the rebels were on the point of flying, when Mæsa and Soæmias rushed out and stopped them; and Bassianus, sword in hand, led them on to the combat. Still the prætorians gave not way, and victory would have declared for Macrinus had he not shamefully fled in the midst of the battle. His troops when assured of his flight declared for Bassianus.
Macrinus fled in disguise, and never stopped till he came to Chalcedon, where he was taken and put to death, and his innocent son shared his fate. His reign had lasted only fourteen months.[c]
