:’) A few (?) years back there was a book, hmm, Goldsomethingorother, author made the ludicrous claim that the gold from the Temple was kept in Rome, then after the city fell, and a hundred years went by, it was all still there, so Justinian (Byz emp, reconquered a good bit of the Roman Empire) found it, nabbed it, moved it back to Israel, and for some reason stashed it in some secret hole in the ground, where it remains. There was even a photo showing some hovel under which it was supposed to have been buried.
Nothing better than hidden treasure!
IIRC there was a similar legend about the loot Alexander the Great got from Persia.
BTW I like the Byzantine empire so much, I may start calling them the Eastern Roman empire. I don’t like the term “byzantine.” IIRC it’s relatively recent usage.
I especially like the 10h century, when they were pushing back the Moslems on all fronts. My old Encyclopedia Britannica noted that their excellent noncommissioned officer corps was the terror of the army.
