The letters of Macrinus had condescended to inform the senate of the slight disturbance occasioned by an impostor in Syria, and a decree immediately passed, declaring the rebel and his family public enemies; with a promise of pardon, however, to such of his deluded adherents as should merit it by an immediate return to their duty. During the twenty days that elapsed from the declaration of the victory of Antoninus (for in so short an interval was the fate of the Roman world decided,) the capital and the provinces, more especially those of the East, were distracted with hopes and fears, agitated with tumult, and stained with a useless effusion of civil blood, since whosoever of the rivals prevailed in Syria must reign over the empire. The specious letters in which the young conqueror announced his victory to the obedient senate were filled with professions of virtue and moderation; the shining examples of Marcus and Augustus, he should ever consider as the great rule of his administration; and he affected to dwell with pride on the striking resemblance of his own age and fortunes with those of Augustus, who in the earliest youth had revenged, by a successful war, the murder of his father. By adopting the style of Marcus Aurelius Antoninus, son of Antoninus and grandson of Severus, he tacitly asserted his hereditary claim to the empire; but, by assuming the tribunitian and proconsular powers before they had been conferred on him by a decree of the senate, he offended the delicacy of Roman prejudice. This new and injudicious violation of the constitution was probably dictated either by the ignorance of his Syrian courtiers, or the fierce disdain of his military followers.
