Myth and science meet at Delphi where the ancient Greeks said the oracle (always a woman) in a trance and often a frenzy spoke on behalf of the gods. Scholarship rejected the claim that vapors rising from the temple's floor inspired the oracle. But now a wealth of evidence compiled by a geologist archaeologist chemist and toxicologist suggests the ancients were right and the discovery of two faults intersecting below the temple indicate the geology could have released intoxicating fumes.
