The writer presents the evidence for the proposition that the real events of the first millennium occurred within a time span of only 300 years. It appears that our historical record repeats in sequential order stories depicting the same events from different perspectives as though they were different occurrences, thus inflating the standard chronology by about 700 years. Archeology — especially the hard data of stratigraphy — may force revisions.
Science can be like that. Earth shaking.
