Without doubt the family had lived securely and delicately in Rome through the reigns of Septimius Severus and his son, growing in wisdom, stature, and prosperity, and, as far as we know, in favour with God and man, until the tragic events of the year 217 made it appear that the fortunes of the family had come to a sudden and decided collapse. The circumstances of the death of Caracalla were typical of that age of sovereignty. As a general rule the knife gave what a dish of mushrooms took away. Caracalla’s government had been cruel and severe in the extreme, but he was adored by the army, with whom he lived and worked, not as Emperor, but as comrade. For them he could never do enough in the way of privileges, for them the treasury was depleted, and cities turned into cemeteries that they might have the booty. Fighting was as natural to him as to a tiger cat; and fighting he died. It was for the pursuit of a campaign against the Parthians that the Emperor and Court had moved to Antioch in Syria, where Julia, his mother, was acting as Secretary of State, while the Emperor was bounding like a panther upon the various cities of Mesopotamia. In the pursuit of her duties, it happened that there came into her hands certain letters warning her of a plot against her son’s life.
With the army at that time was a praefect, Opilius Macrinus by name, a Moorish lawyer of low birth and pedantic habits. He had been procurator to Plautianus, the so-called traitor, whom both Julia and Caracalla had hated. Now Macrinus had been honoured by Severus after Plautianus’ murder, and still stood high in the imperial favour—though he was treated by the Emperor, says Dion, as a sort of buffoon. Macrinus had dreamed that the purple should be his, and was supported in his wish by the African astrologer Serapion, who was obliging enough to prophesy the speedy demise of Aurelius Antonine in Macrinus’ favour.
Julia immediately sent dispatches containing the account of what was going forward to her son, who, as usual, was absent from the city. When these arrived in the camp, Caracalla was just mounting his chariot, and gave orders that the mail should be taken first to Macrinus, who would sift its contents and only bring what was necessary to the Emperor. Thus did Macrinus learn that his treachery was discovered and a death-sentence for real or supposed treason imminent, which unpleasant certainty he resolved to obviate without further delay. In a very few days he had discovered a discontented person willing to do his work, one Martialis, a centurion, whose brother, according to Herodian, had recently been executed for some military offence, or, in Dion’s version, because he was angered at his own tardy promotion. These two discussed the matter and resolved on the extermination of their mutual grievance, Martialis to do the deed.
The opportunity came on the 8th April 217, when Caracalla was on a journey to visit the temple of the Moon at Charrae in Mesopotamia. By the way, he had occasion to dismount for purposes of natural relief, and withdrew somewhat from his staff, thus leaving himself unprotected. Martialis saw his opportunity. On the pretext of having been called, he rushed up and stabbed the defenceless Emperor in the back, then made off, followed by the German officers, who immediately got wind of what had been done. He was the cat’s paw, and suffered the penalty that Macrinus had foreseen would be his. Four days later, and, faute de mieux, the army offered the Empire to this same Macrinus, little wotting for the moment what his part had been in the tragedy they deplored, desiring only a leader against the approaching forces of King Artabanus. As usual, according to Herodian, the Senate breathed a sigh of relief when the Emperor died. In their effete condition they were only too anxious to change masters as often as possible. With a want of political sense and ability, which so well merited the treatment they received at the hands of their tyrants, that august body continually preferred—with an entire lack of statesmanship—the unknown to the known evils of their future.
