Delphic Oracle's Lips May Have Been Loosened by Gas Vapors

The oracle of Delphi in Greece was the telephone psychic of ancient times: People came from all over Europe to call on the Pythia at Mount Parnassus to have their questions about the future answered. Her answers could determine when farmers planted their fields or when an empire declared war. The Pythia, a role filled by different women from about 1400 B.C. to A.D. 381, was the medium through which the god Apollo spoke.

According to legend, Plutarch, a priest at the Temple of Apollo, attributed Pythia's prophetic powers to vapors. Other accounts suggested the vapors may have come from a chasm in the ground.
This traditional explanation, however, has failed to satisfy scientists. In 1927, French geologists surveyed the oracle's shrine and found no evidence of a chasm or rising gases. They dismissed the traditional explanation as a myth.
Their conclusion was aggregated by a modern misconception that vapors and gases could only be produced by volcanic activity.
Now, a four-year study of the area in the vicinity of the shrine is causing archaeologists and other authorities to revisit the notion that intoxicating fumes loosened the lips of the Pythia.
The study, reported in the August issue of Geology, reveals that two faults intersect directly below the Delphic temple. The study also found evidence of hallucinogenic gases rising from a nearby spring and preserved within the temple rock.
"Plutarch made the right observation," said Jelle De Boer, a geologist at Wesleyan University in Middletown, Connecticut, and co-author of the study. "Indeed, there were gases that came through the fractures."
Fractured Landscape
Greece sits at the confluence of three tectonic plates. The shifting of these plates continually stretches and uplifts the area, which is riddled with faults.
Several years ago, Greek researchers found a fault running east to west beneath the oracle's temple. De Boer and his colleagues discovered a second fault, which runs north to south. "Those two faults do cross each other, and therefore interact with each other, below the site," said De Boer.
Interactions of major faults make rock more permeable and create passages through which ground water and gases can travel and rise. From 70 to 100 million years ago, the limestone bedrock underlying the oracle's site lay below sea level, enriched with hydrocarbon deposits.
About every 100 years a major earthquake rattles the faults. The faults are heated by adjacent rocks and the hydrocarbon deposits stored in them are vaporized. These gases mix with ground water and emerge around springs.
De Boer conducted an analysis of these hydrocarbon gases in spring water near the site of the Delphi temple. He found that one is ethylene, which has a sweet smell and produces a narcotic effect described as a floating or disembodied euphoria.
"Ethylene inhalation is a serious contender for explaining the trance and behavior of the Pythia," said Diane Harris-Cline, a classics professor at The George Washington University in Washington, D.C.
"Combined with social expectations, a woman in a confined space could be induced to spout off oracles," she said.
According to traditional explanations, the Pythia derived her prophecies in a small, enclosed chamber in the basement of the temple. De Boer said that if the Pythia went to the chamber once a month, as tradition says, she could have been exposed to concentrations of the narcotic gas that were strong enough to induce a trance-like state.
Waning Power
The power of the Delphic oracle fluctuated and eventually lost favor as Christianity became the dominant religion of the land, said De Boer. Moreover, ancient legend suggests that the concentration of the vapors became weaker—possibly because the absence of a major earthquake failed to keep Earth's narcotic juices flowing.
Today, the water that helped transport the gases to the Delphic temple is tapped and siphoned above the temple to supply the modern town of Delphi.
The work by De Boer and his colleagues is an example of modern science helping archaeologists understand how ancient peoples lived. Another example among the ancient Greeks is the belief in Poseidon as the god of the sea and earthquakes. According to Harris-Cline, modern science associates the two with tectonic movement deep under the sea.
"Our scientific techniques are just beginning to detect the natural phenomena which the Greeks celebrated and appreciated 2,500 years ago with ritual activities at these special places," she said.
Ancient Forecasting at Delphi The Oracle of Delphi, which dates back to 1200 B.C., was the most important shrine in Greece. Built around a sacred spring, it was considered the center of the world.
People came from all over Greece and beyond to have their questions about the future answered by the Pythia, the priestess at the Temple of Apollo. Her predictions and announcements were used to determine events and activities ranging from when a farmer planted his seeds to when an empire declared war.
A consultation with Pythia began with the sacrifice of a goat. Pythia mounted a tripod and sat while awaiting divine inspiration, then conveyed her pronouncements to the seekers.
The Oracle of Delphi shrine was regarded as independent, its priests not associated with any strict religious dogma for the worship of Greek gods. Greek states eager to be in the Oracle's good graces sent elaborate gifts to the shrine, which made it a storehouse of fabulous art treasures.
The power of the Delphic oracle fluctuated, and finally lost favor when Christianity spread widely.
The New York Times recently had an article on The Oracle of Delphi. The Oracle apparently was there, but the woman the Greeks described with a god given power to see the future didn't have any truth to it. What was true was there was a woman there. Gas would rise through cracks in the floor which she would inhale and which caused her to start making predictions as she ran around and screamed in a frenzy. She would advise people on anything from their sex life to government. The people being advised would be amazed by her frenzy and think it was holy.
The oracle was very important,and the girl who was there changed many times. Before every vision she would go into the basement and inhale the intoxicating fumes. Some say then she would tell the vision to priests who would write it down; others say she would say it directly to the petitioners.
For starters, the site was founded at the Gulf of Corinth in 1200 B.C. and eventually the temple was built. It was to become one of the most important ancient Greek temples. Originally it was built for the Earth goddess, Gaea but by the eight century B.C., it was already dedicated to Apollo. Apart from being the god of light and, most famously, music and poetry, Apollo was the god of prophecy. Greeks believed that this site was the center of the world. Considering that they thought the site had people who could tell the future and a shrine to one of the most important gods, it only makes sense that it was believed that it was the center of the world.
With the rise of Christianity, the temple started to lose its excitement and importance and began to decay. Though the Roman emperor Julius the Apostate tried to reinstate the oracle, she whined that her power had faded.
The oracle actually had some interesting insight though, and before Socrates was executed the oracle called him the wisest man to have ever lived.
French archeologists started excavating the site around 1892, and it was all declared a fake by A.P. Oppe, a famous English philosopher, who was there in 1904. Another blow to Greek Mythology came when Pierre Amandry, a French archaeologist, declared in a book on Delphi that the region had no volcanism and therefore could not provide intoxicating vapors. In 1981 the final blow was struck. Dr. Boer came not to find out the truth behind the oracle, but merely to help the Greek government with whether or not they could place nuclear reactors there. His job was just to find hidden faults. Then, a lucky thing happened. The Greek government had carved out a large part of the mountain the oracle was located on. Dr. Boer saw a fault line hidden in the mountain and followed it. He followed it all the way to the oracle, thus at last proving it a fake.
The oracle still exists as a ruin, and people can go see what used to be the center of the earth today.

Dating back to 1400 BC, the Oracle of Delphi was the most important shrine in all Greece, and in theory all Greeks respected its independence. Built around a sacred spring, Delphi was considered to be the omphalos - the center (literally navel) of the world.
People came from all over Greece and beyond to have their questions about the future answered by the Pythia, the priestess of Apollo. And her answers, usually cryptic, could determine the course of everything from when a farmer planted his seedlings, to when an empire declared war.
Arguments over the correct interpretation of an oracle were common, but the oracle was always happy to give another prophecy if more gold was provided. A good example is the famous incident before the Battle of Salamis when the Pythia first predicted doom and later predicted that a 'wooden wall' (interpreted by the Athenians to mean their ships) would save them.
The lack of a strict religious dogma associated with the worship of Greek gods also encouraged scholars to congregate at Delphi, and it became a focal point for intellectual enquiry, as well as an occasional meeting place where rivals could negotiate.
Delphi became a fantastic showcase of art treasures and all Greek states would send rich gifts to keep the Oracle on their side. It finally came to an end in the 4th century AD when a newly Christian Rome proscribed its prophesying.
