Yet, in the contest between Niger and Severus, a single city deserves an honorable exception. As Byzantium was one of the greatest passages from Europe into Asia, it had been provided with a strong garrison, and a fleet of five hundred vessels was anchored in the harbor. The impetuosity of Severus disappointed this prudent scheme of defence; he left to his generals the siege of Byzantium, forced the less guarded passage of the Hellespont, and, impatient of a meaner enemy, pressed forward to encounter his rival. Byzantium, attacked by a numerous and increasing army, and afterwards by the whole naval power of the empire, sustained a siege of three years, and remained faithful to the name and memory of Niger. The citizens and soldiers (we know not from what cause) were animated with equal fury; several of the principal officers of Niger, who despaired of, or who disdained, a pardon, had thrown themselves into this last refuge: the fortifications were esteemed impregnable, and, in the defence of the place, a celebrated engineer displayed all the mechanic powers known to the ancients. Byzantium, at length, surrendered to famine. The magistrates and soldiers were put to the sword, the walls demolished, the privileges suppressed, and the destined capital of the East subsisted only as an open village, subject to the insulting jurisdiction of Perinthus. The historian Dion, who had admired the flourishing, and lamented the desolate, state of Byzantium, accused the revenge of Severus, for depriving the Roman people of the strongest bulwark against the barbarians of Pontus and Asia The truth of this observation was but too well justified in the succeeding age, when the Gothic fleets covered the Euxine, and passed through the undefined Bosphorus into the centre of the Mediterranean. Both Niger and Albinus were discovered and put to death in their flight from the field of battle. Their fate excited neither surprise nor compassion. They had staked their lives against the chance of empire, and suffered what they would have inflicted; nor did Severus claim the arrogant superiority of suffering his rivals to live in a private station. But his unforgiving temper, stimulated by avarice, indulged a spirit of revenge, where there was no room for apprehension. The most considerable of the provincials, who, without any dislike to the fortunate candidate, had obeyed the governor under whose authority they were accidentally placed, were punished by death, exile, and especially by the confiscation of their estates. Many cities of the East were stripped of their ancient honors, and obliged to pay, into the treasury of Severus, four times the amount of the sums contributed by them for the service of Niger.
