Antiquities of the Jews, fit the thirty-sixth, concluding Book XVII

XVII.13.341 says of Herod's son Archelaus:

Moreover, he transgressed the law of our fathers and married Glaphyra, the daughter of Archelaus, who had been the wife of his brother Alexander, which Alexander had three children by her, while it was a thing detestable among the Jews to marry the brother's wife.

You may, as I was, be thinking, "But the Torah commands levirate marriage!" In fact, the Torah commands levirate marriage when the deceased has left no children. When he has, there is no mitzva, so Josephus is not contradicting the Torah to describe it as "detestable".

Archelaus, at the beginning of his reign, was welcomed as a great relief from his murderous father; however, after ten years, "his brethren, and the principal men of Judea and Samaria, not being able to bear his barbarous and tyrannical usage of them, accused him before Caesar." XVII.13.344:

Caesar, upon hearing what certain accusers of his had to say, and what reply he could make, both banished him, and appointed Vienna, a city of Gaul, to be the place of his habitation, and took his money away from him.

One doesn't think of kings of the Jews as being exiled to Vienna, but it did happen. (Or at least, to Vienne, in western France rather than the capital of Austria, Vienna being the name it had under the Romans.)

XVII.13.350 reveals an attitude towards remarriage suggestive (and possibly not surprisingly, given the time) of Christianity, rather than Judaism:

( 'Didst not thou pledge thy faith to me? ... Yet hast thou forgotten the affection I bare to thee, out of a desire of a second husband. ... However, I will not forget thy former kind affection for me, but will set thee free from every such reproachful action, and cause thee to be mine again, as thou once wast.' ... [I]n a few days' time she departed this life. )

In modern Judaism the period of mourning, which is eleven months for other close relations, is reduced to just one month for spouses, to allow speedy remarrying, for, as it says in Genesis 2, "It is not good for man to be alone."
