[645] And now, upon the news that Antonius was approaching, Sabinus took courage at Rome, and assembled those cohorts of soldiers that kept watch by night, and in the night time seized upon the capitol; and, as the day came on, many men of character came over to him, with Domitian, his brother's son, whose encouragement was of very great weight for the compassing the government. Now Vitellius was not much concerned at this Primus, but was very angry with those that had revolted with Sabinus; and thirsting, out of his own natural barbarity, after noble blood, he sent out that part of the army which came along with him to fight against the capitol; and many bold actions were done on this side, and on the side of those that held the temple. But at last, the soldiers that came from Germany, being too numerous for the others, got the hill into their possession, where Domitian, with many other of the principal Romans, providentially escaped, while the rest of the multitude were entirely cut to pieces, and Sabinus himself was brought to Vitellius, and then slain; the soldiers also plundered the temple of its ornaments, and set it on fire. But now within a day's time came Antonius, with his army, and were met by Vitellius and his army; and having had a battle in three several places, the last were all destroyed. Then did Vitellius come out of the palace, in his cups, and satiated with an extravagant and luxurious meal, as in the last extremity, and being drawn along through the multitude, and abused with all sorts of torments, had his head cut off in the midst of Rome, having retained the government eight months and five days ¹ and had he lived much longer, I cannot but think the empire would not have been sufficient for his lust. Of the others that were slain, were numbered above fifty thousand. This battle was fought on the third day of the month Apelleus [Casleu]; on the next day Mucianus came into the city with his army, and ordered Antonius and his men to leave off killing; for they were still searching the houses, and killed many of Vitellius's soldiers, and many of the populace, as supposing them to be of his party, preventing by their rage any accurate distinction between them and others. He then produced Domitian, and recommended him to the multitude, until his father should come himself; so the people being now freed from their fears, made acclamations of joy for Vespasian, as for their emperor, and kept festival days for his confirmation, and for the destruction of Vitellius.
