In that extended list of V’s note, it would be nice were it easy to pin BCE, CE dates to many of them. It is extensive and gets in a jumble. Not even Ages in Chaos did this well as I recall.
He used synchronisms and 'hard' dates. Ramses "the Great" was rc dated by his guts (from inside one of his canopic jars) and was, as predicted, (V said "nearly 800 years") younger than the conventional pseudochronology must have him be. Soooo, the results were published and the spurious excuse was, the jar (the second jar had an aromatic salve) was reused. BTW, despite any claim to the contrary, there had never previously been any doubt that they were Ramses II's, and afaik there's zero evidence that any pharaonic-era canopic jars were ever reused in a later burial. And in the Theses, #245 -- "Tiles of buildings erected by Ramses II (in Kantir) which have Greek letters on the back, are products of Greek laborers in the service of the pharaoh. The letters are genuine Greek letters of the sixth century."
