Pythia

Pythia is the name of a priestess from Delphi at the Temple of Apollo, also known as the Oracle of Delphi. She was known for her hallucinations, translated into revelations or prophecies, spoken in a weird tongue, said as it came from the Gods directly. Some historici think it was because of the use of certain drugs, others think she acted under the influence of certain gasses (Greece is a rather seismic region, as you know), or it might have been some sort of self-hypnotic or mental state of whatever.
