Mostly fire, that's a good witness.
I would certainly prefer for some to emerge though, blueprints of the Temple of Artemis for example could become handy to someone wanting to built something really great (at all metrics).
(I know we short of have them, by the ruins, it's the mindset that's missing, same with the Temple of Hathor at Dendera too, to be fair)
We read about all these things and we think that we would maybe feel small in front of them.
Nope, at the contrary, we feel ascended the moment we're there as long as we are people of the world and we have traveled enough to know how people can be both bitter and small and bigger than life and beautiful.
It's the small us usually who baptize such great works as god-made and nonsense. It's people-made, plain and simple.
