Who Was the Pythia? The Women Behind the Oracle of Delphi

The woman at the centre of the ancient world's most powerful oracle has no name in the historical record. Pythia was a title, not a person. Over the roughly thousand years that the Oracle of Delphi operated, dozens of women held the role, possibly hundreds. We know almost nothing about any of them individually, which is worth remembering when the accounts start sounding authoritative.

Who Was the Pythia?

Suppliants did not go into the adyton, the innermost part of the temple. What they received was a version of what happened in there, mediated by the priests who surrounded the process, written down in their hand, often rendered into hexameter verse before it reached anyone who had actually asked a question. The Pythia spoke. Others interpreted.

She was chosen from the women of Delphi, originally required to be a young virgin, though later sources suggest the requirement shifted to older women possibly after an incident of assault that compelled the sanctuary's administrators to change the selection criteria. She held the position for life. Before each consultation she fasted and bathed in the Castalian spring. Ancient accounts called this purification. Then she descended into the adyton, took her seat on a tripod over a fissure in the rock, chewed laurel leaves, and waited.

What Happened Inside the Adyton?

What happened next is the question that has occupied classicists, geologists and toxicologists for the better part of a century.

The ancient accounts are consistent on certain points. The Pythia entered a state that observers described as enthusiasm. It is a word that has lost most of its force in English. In its original Greek sense it meant being filled with the god. She shook. She spoke in ways that were sometimes coherent and sometimes not. The priests who attended her rendered her words into the hexameter verse that suppliants received as their answer. Whether she was genuinely in an altered state, performing one, or somewhere in the complicated territory between the two is a question the sources cannot resolve, partly because the sources did not think it was a question worth asking. The god was present. The woman was the vessel. The sources were not particularly interested in whether that framing suited the women involved. That question simply did not occur to them.

The Ethylene Theory

Nobody had a satisfying explanation for what was actually happening until the late twentieth century. The explanation, when it finally arrived, came from an unlikely direction. A geologist named Jelle de Boer and a toxicologist, Henry Schwarcz, argued that geological conditions beneath the Temple of Apollo could have released ethylene gas through intersecting fault lines directly under the site. Ethylene at low concentrations produces a mild euphoric dissociation. At higher concentrations, it is considerably less pleasant. Push far enough and you get loss of consciousness, convulsions. De Boer and Schwarcz argued that the ancient accounts of the Pythia's behaviour, including descriptions of her being carried out of the adyton after particularly intense sessions, fit that range surprisingly well. Later geological surveys identified fault lines beneath the sanctuary, suggesting that earlier scholars may have dismissed the possibility too quickly. The theory remains contested, but it has not been comfortably explained away either.

The Ambiguity Was the Point

This does not mean the Pythia was simply drugged and her responses were meaningless. The altered state, whatever its cause, produced something that thousands of people over hundreds of years found worth travelling considerable distances and paying considerable fees to receive. The answers the Oracle gave were almost always ambiguous, but ambiguity is not the same as uselessness. The ambiguity was the point, in a way. A question returned in a form that required interpretation, forcing the questioner to actually think. That had practical value, whatever you make of the gas. Themistocles did not win at Salamis because the Oracle told him what to do. He already knew what he wanted to do. What the Oracle gave him was a reason everyone else would accept.

What the Pythia's Experience Actually Looked Like

The Pythia's own experience of the process is largely invisible to us. One account, from Plutarch, who served as a priest at Delphi in the first century AD, describes a consultation that went badly. The Pythia was reportedly forced into the adyton at an inauspicious moment, against the signs, and emerged in a state of severe distress from which she did not recover, dying within days. Plutarch's account is the closest thing we have to an insider's description of what the process could do to the woman at its centre. It does not read like a description of theatre.

What it reads like is an account of someone under considerable pressure, in a role that the evidence suggests was not straightforwardly chosen. Whether the women who held it viewed it as an honour, an obligation, or both is impossible to know from the surviving evidence. The Pythia's role was sacred and, in the terms available to her world, enormously prestigious. The god had, in the logic of the sanctuary, chosen them. Whether that framing was one they would have chosen for themselves is a question the sources were not equipped to ask, and did not.

The End of the Oracle

The last Pythia spoke sometime in the fourth century AD. The emperor Julian's attempt to consult the Oracle in 362 AD received a response so desolate that it has been read ever since as a farewell: the springs had run dry. The laurel was silent. Whatever had spoken through Delphi for a thousand years had apparently finished, and left no explanation. Whether that response came from a Pythia in the traditional sense, or from a priest improvising in a sanctuary that had largely stopped functioning, nobody can say. It ended there.

The women who held the title across ten centuries left almost nothing of themselves in the record. They were the voice of the god, which meant they were not permitted to be anything else. The Oracle spoke. The Pythia was the instrument through which it did so. That she was a person, with a life before the tripod and presumably some kind of life after each consultation, is something the ancient world did not find worth recording.

We are left with the gas, the tripod, the laurel leaves, and the hexameter verse. The woman herself remains almost entirely out of reach.
