From the 25th Dynasty. To put it in historical context, from about 760 BC to about 656 BC. Or, to put it another way, about the time of the Babylonian Exile of the Jews.
I wondered where I put that!
Is this kind of like the guy who”Found”Jesus?I didn’t know he was lost????
Oh, puleez! No tomb can be lost in just 30 short years of sifting sands. As if the 1980s were ancient times. I’m sure the locals knew exactly where it was.
