Pythia at Delphi and the vapors from the ground evidences

I’ve always heard that the Pythia at Delphi went into trances because of vapors from the ground. Is there any real evidence that she was intoxicated by gases, or is this just a myth?

Ancient writers do describe the Pythia entering trance-like states while delivering prophecies. For a long time, the idea of a “gaseous fissure” was debated, but more recent geological studies suggest that ethylene-emitting springs may have existed beneath the site. Ethylene can cause mild intoxication and euphoria, which could help explain her altered state. While not proven beyond doubt, this theory offers a plausible scientific explanation alongside the literary evidence.

There’s also evidence from archaeology and ancient texts that the Pythia used ritual practices—such as inhaling vapors from chasms or sitting on a tripod—before giving prophecies. Some scholars think these physical and ritual conditions amplified a naturally trance-like state, even without strong intoxicating gases. So it could be a mix of environmental, physiological, and ceremonial factors that produced her prophetic demeanor.

Thanks a lot! I hadn’t considered the ritual aspect combined with natural causes. That really helps explain why she might enter trances without needing a “mystical” explanation.
