This is probably accurate. It makes his journey a lot more sensible than the Chaldean claim.
In any case, Jews themselves don't even agree on who is Jewish and who isn't; they were never a race until the Babylonian Jews used their influence on Cyrus and invented themselves as a 'Master Race' and made all other Jews second and third class subjects.
Thanks.
I settled the question of who's a Jew for myself some time ago. If they say they are Jewish, IMO they're Jewish.
Cyrus was Emmanuel.
