Pythia was a priestess who made predictions and prophesied oracles in the Temple of Apollo.
It was believed to be the god himself speaking through the oracle.
Pythia never gave a direct answer but spoke in allegories and hidden meanings.
Even today it is a mystery how she made prophecies. But it was said to be from the steam coming out of a cleft in a rock.
Investigators have not reached a specific conclusion but it is believed to have been the inhalation of certain gases and fumes. Italian study says it was a mixture of carbon dioxide and methane.
