This is assuming the smoking crack was real and not special effects and the strange oracular behavior and cryptic utterances weren’t all for show.
Over a hundred years ago, during the debunking golden age, a French archaeologist went to Delphi and supposedly dug on the site, disproving once and for all that any of the ancient description was correct.
No one challenged this view for about a century.
Then a geologist from (I think) the Netherlands visited the site for a survey, noted the larger of the two faults ran right directly through the center of the temple (the long axis), and without worrying about a thing, published the results.
He bumped into a prof from the US who told him that had all been disproved long ago, and upbraided the latter by pointing out that he was a geologist who had been on the site for a good while, so how’s about shuttin’ yer trap. (Made that up) He actually said, go see for yourself, it’s clear and obvious, anyone can see it, and you’ll be surprised that no one had noticed it before.
All correct.
The second fault is smaller, and crosses the larger one at approx right angle — right where the pythoness used to sit.
The faults used to have water perking out of them, and releasing the gases (which probably were the force behind the water bubbling out). The identity of the gases was determined by geological studies along the fault lines, approved by the Greek gov’t.
