The authority of the new sovereign had been ratified by the cheerful submission of the senate and provinces. They exulted in their unexpected deliverance from a hated tyrant, and it seemed of little consequence to examine into the virtues of the successor of Caracalla. But as soon as the first transports of joy and surprise had subsided, they began to scrutinize the merits of Macrinus with a critical severity, and to arraign the hasty choice of the army. It had hitherto been considered as a fundamental maxim of the constitution, that the emperor must be always chosen in the senate, and the sovereign power, no longer exercised by the whole body, was always delegated to one of its members. But Macrinus was not a senator. The sudden elevation of the Prætorian præfects betrayed the meanness of their origin; and the equestrian order was still in possession of that great office, which commanded with arbitrary sway the lives and fortunes of the senate. A murmur of indignation was heard, that a man, whose obscure extraction had never been illustrated by any signal service, should dare to invest himself with the purple, instead of bestowing it on some distinguished senator, equal in birth and dignity to the splendor of the Imperial station. As soon as the character of Macrinus was surveyed by the sharp eye of discontent, some vices, and many defects, were easily discovered. The choice of his ministers was in many instances justly censured, and the dissatisfied people, with their usual candor, accused at once his indolent tameness and his excessive severity. His rash ambition had climbed a height where it was difficult to stand with firmness, and impossible to fall without instant destruction. Trained in the arts of courts and the forms of civil business, he trembled in the presence of the fierce and undisciplined multitude, over whom he had assumed the command; his military talents were despised, and his personal courage suspected; a whisper that circulated in the camp, disclosed the fatal secret of the conspiracy against the late emperor, aggravated the guilt of murder by the baseness of hypocrisy, and heightened contempt by detestation. To alienate the soldiers, and to provoke inevitable ruin, the character of a reformer was only wanting; and such was the peculiar hardship of his fate, that Macrinus was compelled to exercise that invidious office. The prodigality of Caracalla had left behind it a long train of ruin and disorder; and if that worthless tyrant had been capable of reflecting on the sure consequences of his own conduct, he would perhaps have enjoyed the dark prospect of the distress and calamities which he bequeathed to his successors.
