Their aversion, confirmed by years, and fomented by the arts of their interested favorites, broke out in childish, and gradually in more serious competitions; and, at length, divided the theatre, the circus, and the court, into two factions, actuated by the hopes and fears of their respective leaders. The prudent emperor endeavored, by every expedient of advice and authority, to allay this growing animosity. The unhappy discord of his sons clouded all his prospects, and threatened to overturn a throne raised with so much labor, cemented with so much blood, and guarded with every defence of arms and treasure. With an impartial hand he maintained between them an exact balance of favor, conferred on both the rank of Augustus, with the revered name of Antoninus; and for the first time the Roman world beheld three emperors. Yet even this equal conduct served only to inflame the contest, whilst the fierce Caracalla asserted the right of primogeniture, and the milder Geta courted the affections of the people and the soldiers. In the anguish of a disappointed father, Severus foretold that the weaker of his sons would fall a sacrifice to the stronger; who, in his turn, would be ruined by his own vices.

He immediately passed the walls of Hadrian and Antoninus, and entered the enemy’s country, with a design of completing the long attempted conquest of Britain. He penetrated to the northern extremity of the island, without meeting an enemy. But the concealed ambuscades of the Caledonians, who hung unseen on the rear and flanks of his army, the coldness of the climate and the severity of a winter march across the hills and morasses of Scotland, are reported to have cost the Romans above fifty thousand men. The Caledonians at length yielded to the powerful and obstinate attack, sued for peace, and surrendered a part of their arms, and a large tract of territory. But their apparent submission lasted no longer than the present terror. As soon as the Roman legions had retired,
