What of the census in Luke?

There is a new solution now">. Pick the eclipse of Jan 10, 1 Bc as the one just before death of Herod. Then we know there was a registration to take oath of allegiance to Augustus before he was named "Father of his country" Feb 5, 2 BC. Real governor of Palestine would have gone to Rome, put Quirinius in as acting governor for the registration. As to coins showing successors began to rule in 4 BC - this sort of pattern is well known in ancient things, and Herod had special reason:was in bad with Augustus, wanted to use names of Hasmoneans.
