his cousins, of whom Dalmatius and Hannibalianus were the most illustrious, the Patrician Optatus, who had married a sister of the late emperor, and the Præfect Ablavius, whose power and riches had inspired him with some hopes of obtaining the purple. If it were necessary to aggravate the horrors of this bloody scene, we might add, that Constantius himself had espoused the daughter of his uncle Julius, and that he had bestowed his sister in marriage on his cousin Hannibalianus. These alliances, which the policy of Constantine, regardless of the public prejudice, 51 had formed between the several branches of the Imperial house, served only to convince mankind, that these princes were as cold to the endearments of conjugal affection, as they were insensible to the ties of consanguinity, and the moving entreaties of youth and innocence. Of so numerous a family, Gallus and Julian alone, the two youngest children of Julius Constantius, were saved from the hands of the assassins, till their rage, satiated with slaughter, had in some measure subsided. The emperor Constantius, who, in the absence of his brothers, was the most obnoxious to guilt and reproach, discovered, on some future occasions, a faint and transient remorse for those cruelties which the perfidious counsels of his ministers, and the irresistible violence of the troops, had extorted from his unexperienced youth. 52 50 (return) [ I have related this singular anecdote on the authority of Philostorgius, l. ii. c. 16. But if such a pretext was ever used by Constantius and his adherents, it was laid aside with contempt, as soon as it served their immediate purpose. Athanasius (tom. i. p. 856) mention the oath which Constantius had taken for the security of his kinsmen. ——The authority of Philostorgius is so suspicious, as not to be sufficient to establish this fact, which Gibbon has inserted in his history as certain, while in the note he appears to doubt it.—G.]
