[324] WHEN these affairs had been thus settled by Caesar, a certain young man, by birth a Jew, but brought up by a Roman freed-man in the city Sidon, ingrafted himself into the kindred of Herod, by the resemblance of his countenance, which those that saw him attested to be that of Alexander, the son of Herod, whom he had slain; and this was an incitement to him to endeavor to obtain the government; so he took to him as an assistant a man of his own country, (one that was well acquainted with the affairs of the palace, but, on other accounts, an ill man, and one whose nature made him capable of causing great disturbances to the public, and one that became a teacher of such a mischievous contrivance to the other,) and declared himself to be Alexander, and the son of Herod, but stolen away. by one of those that were sent to slay him, who, in reality, slew other men, in order to deceive the spectators, but saved both him and his brother Aristobulus. Thus was this man elated, and able to impose on those that came to him; and when he was come to Crete, he made all the Jews that came to discourse with him believe him [to be Alexander]. And when he had gotten much money which had been presented to him there, he passed over to Melos, where he got much more money than he had before, out of the belief they had that he was of the royal family, and their hopes that he would recover his father's principality, and reward his benefactors; so he made haste to Rome, and was conducted thither by those strangers who entertained him. He was also so fortunate, as, upon his landing at Dicearchia, to bring the Jews that were there into the same delusion; and not only other people, but also all those that had been great with Herod, or had a kindness for him, joined themselves to this man as to their king. The cause of it was this, that men were glad of his pretenses, which were seconded by the likeness of his countenance, which made those that had been acquainted with Alexander strongly to believe that he was no other but the very same person, which they also confirmed to others by oath; insomuch that when the report went about him that he was coming to Rome, the whole multitude of the Jews that were there went out to meet him, ascribing it to Divine Providence that he has so unexpectedly escaped, and being very joyful on account of his mother's family. And when he was come, he was carried in a royal litter through the streets; and all the ornaments about him were such as kings are adorned withal; and this was at the expense of those that entertained him. The multitude also flocked about him greatly, and made mighty acclamations to him, and nothing was omitted which could be thought suitable to such as had been so unexpectedly preserved.
