More famously at Delphi were its oracles. The Oracle of Delphi inspired The Matrix’s Oracle. She was always a priestess and resided in the Temple of Apollo, in which the god Apollo would deliver prophecies through her. People from all over the Greek-influenced world (which included Egypt and Turkey) travelled to Delphi to consult her on all major undertakings, such as war. She would allegedly inhale mysterious vapours from a chasm in the temple, falling into a trance and hence allowing Apollo to possess her spirit. For this reason the temple was always described by visitors as sweet-smelling.
Scientific theories on the nature of the hallucinogenic gas posit that it could be ethylene or ethane, sweet smelling hydrocarbons that are known to produce violent trances. However, geology analysis of the rocks at the temple do not seem to support that. So similar to The Matrix, nobody knows what is going on.
