AnnOMaly:
Walk me through this. Where did you get the years for the high priests? I couldn't locate them in Josephus. With which other sources do the year figures correspond?
I got the years from Wikipedia (ultimately from other Jewish sources). But the periods are confirmed by Josephus. Antiquities of the Jews, Book XI, Chapter 7:
2. Now when John had departed this life, his son Jaddua succeeded in the high priesthood. He had a brother, whose name was Manasseh. :Now there was one Sanballat, who was sent by Darius, the last king [of Persia]*, into Samaria. He was a Cutheam by birth; of which stock were the Samaritans also. This man knew that the city Jerusalem was a famous city, and that their kings had given a great deal of trouble to the Assyrians, and the people of Celesyria; so that he willingly gave his daughter, whose name was Nicaso, in marriage to Manasseh, as thinking this alliance by marriage would be a pledge and security that the nation of the Jews should continue their good-will to him.
* "[of Persia]" is an interpolation in the translation, not added by me.
Chapter 8 immediately continues into dealings with Alexander the Great, including references to Darius as his contemporary. Josephus is therefore not discussing Darius II.
Note also that Josephus (earlier in Chapter 7) refers to "another Artaxerxes" (Artaxerxes II [Mnemon]) as a contemporary of John (Johanan), after the Darius (II) contemporary with Judas (Joiada), but before the Darius (III) contemporary with Jaddua.
