gdpetti said:Maybe I misunderstood it, but wasn't that '300 years' of missing time actually a lack of any recording of events in certain areas of the planet for that designated period of time?
No, according to the Cs it is a literal addition of around 480 years. So what we think of as the year 1 AD would actually fall around 480 AD. Whether that is correct or not will require a lot more research.
And to answer lilies' question, no, the book strictly deals with the relative chronology of (roughly) the first century, without any drastic redating. That would require a whole other volume (or several). However, some alternative datings for events within this timeframe are suggested.
