If his two competitors, reconciled by their common danger, had advanced upon him without delay, perhaps Severus would have sunk under their united effort. Had they even attacked him, at the same time, with separate views and separate armies, the contest might have been long and doubtful. But they fell, singly and successively, an easy prey to the arts as well as arms of their subtle enemy, lulled into security by the moderation of his professions, and overwhelmed by the rapidity of his action. He first marched against Niger, whose reputation and power he the most dreaded: but he declined any hostile declarations, suppressed the name of his antagonist, and only signified to the senate and people his intention of regulating the eastern provinces. In private, he spoke of Niger, his old friend and intended successor, with the most affectionate regard, and highly applauded his generous design of revenging the murder of Pertinax. To punish the vile usurper of the throne, was the duty of every Roman general. To persevere in arms, and to resist a lawful emperor, acknowledged by the senate, would alone render him criminal. The sons of Niger had fallen into his hands among the children of the provincial governors, detained at Rome as pledges for the loyalty of their parents. As long as the power of Niger inspired terror, or even respect, they were educated with the most tender care, with the children of Severus himself; but they were soon involved in their father’s ruin, and removed first by exile, and afterwards by death, from the eye of public compassion.
