Could the Josephus timeline be wrong(deliberately or otherwise)?
I'll wager that the Joseph mentioned as Herod's uncle\brother-in-law and Mariamme, Herod's wife, were the Joseph and Mary who fled to Egypt- and that Joseph is the biblical Joseph of Aramithea. The symbol of Joseph the worker is a flowering staff. Seems like an obvious reference to the flowering hawthorne and the first wives of both were called Eschia or Salome.
