So then, after the departure of Nero, Galba seized the government; and ere long, on Galba being slain, Otho secured it. Then Vitellius from Gaul, trusting to the armies which he commanded, entered the city, and having killed Otho, assumed the sovereignty. This afterwards passed to Vespasian, and although that was accomplished by evil means, yet it had the good effect of rescuing the state from the hands of the wicked. While Vespasian was besieging Jerusalem, he took possession of the imperial power; and as the fashion is, he was saluted as emperor by the army, with a diadem placed upon his head.
He made his son Titus, Cæsar; and assigned him a portion of the forces, along with the task of continuing the siege of Jerusalem. Vespasian set out for Rome, and was received with the greatest favor by the senate and people; and Vitellius having killed himself, his hold of the sovereign power was fully confirmed. The Jews, meanwhile, being closely besieged, as no chance either of peace or surrender was allowed them, were at length perishing from famine, and the streets began everywhere to be filled with dead bodies, for the duty of burying them could no longer be performed.
Moreover, they ventured on eating all things of the most abominable nature, and did not even abstain from human bodies, except those which putrefaction had already laid hold of and thus excluded from use as food. The Romans, accordingly, rushed in upon the exhausted defenders of the city. And it so happened that the whole multitude from the country, and from other towns of Judæa, had then assembled for the day of the Passover: doubtless, because it pleased God that the impious race should be given over to destruction at the very time of the year at which they had crucified the Lord.
The Pharisees for a time maintained their ground most boldly in defense of the temple, and at length, with minds obstinately bent on death, they, of their own accord, committed themselves to the flames. The number of those who suffered death is related to have been eleven hundred thousand, and one hundred thousand were taken captive and sold. Titus is said, after calling a council, to have first deliberated whether he should destroy the temple, a structure of such extraordinary work.
For it seemed good to some that a sacred edifice, distinguished above all human achievements, ought not to be destroyed, inasmuch as, if preserved, it would furnish an evidence of Roman moderation, but, if destroyed, would serve for a perpetual proof of Roman cruelty. But on the opposite side, others and Titus himself thought that the temple ought specially to be overthrown, in order that the religion of the Jews and of the Christians might more thoroughly be subverted; for that these religions, although contrary to each other, had nevertheless proceeded from the same authors; that the Christians had sprung up from among the Jews; and that, if the root were extirpated, the offshoot would speedily perish.
Thus, according to the divine will, the minds of all being inflamed, the temple was destroyed, three hundred and thirty-one years ago. And this last overthrow of the temple, and final captivity of the Jews, by which, being exiles from their native land, they are beheld scattered through the whole world, furnish a daily demonstration to the world, that they have been punished on no other account than for the impious hands which they laid upon Christ. For though on other occasions they were often given over to captivity on account of their sins, yet they never paid the penalty of slavery beyond a period of seventy years.
