When the ancient Greeks and Romans had a question of great import, they traveled to the navel (omphalos) of the world, which they believed to be at Delphi, on the steep slopes of Mount Parnassus in Greece (see map below).
They climbed up the Sacred Way, past about 3,000 statues and various temples and shrines, until they reached the Temple of Apollo. (This post is apropos of our discussion about Apollo the other day.)
Mount Parnassus was Apollo’s mountain — the mountain of wisdom and music, the place where Apollo had given Orpheus his lyre and taught him to play it, a place that other artistic places (such as Montparnasse in Paris) still try to evoke today.
Because Apollo could see the future, he would have the answer to any question, here at his temple.
And he gave his answer through a woman, the Pythia (pictured above). She would sit above a chasm in the rock through which the god sent vapors (pneuma) that put the woman in a trance. Thus possessed, the Pythia would babble, and priests were at hand to transcribe her words into beautiful hexameter which they gave to the individual who had asked a question.
The answer was coherent syntactically but not necessarily substantively. You recall that both King Croesus and Socrates, for example, had received answers from the Pythia that were ambiguous at best (disastrously so, in Croesus’ case).
But nobody could dispute the power of the god, or rather of his vapors.
And that remains true even today. The vapors are real, it turns out. Mount Parnassus sits atop several very active faults. The earth below constantly rubs and often quakes, grinding the rock until it emits … vapors.
Which vapors? Methane and ethane, apparently. Even the spring water at the site contains ethylene.
In short, even the scientists who go there today, if they hang out there long enough, if they inhale and ingest, may enter the trance of the Pythia and receive the ambiguous wisdom of Apollo.
