Today, historian Rob Zaretsky travels back to the future at Delphi. The University of Houston presents this series about the machines that make our civilization run, and the people whose ingenuity created them.
They were running wildly around, as if their hair was on fire. The nation was in danger, yet the nature of the threat was unclear. Accounts conflicted; the "chatter" was garbled; leaders argued over strategies.
Perhaps this sounds familiar: it certainly would to an ancient Greek. This was the situation in Athens in 480 BCE, on the eve of the Persian invasion. The Greeks were at loggerheads: how to defend themselves against the approaching armies of Xerxes? For an answer, they turned to a traditional source of intelligence: the oracle at Delphi.
Delphi boasted a temple to Apollo, home of the Pythia, a priestess who offered counsel to supplicants seeking guidance. Her answers most often were, well, oracular: enigmatic and elusive. There were both physical and political reasons for her ambiguity.
Ancient historians, like Plutarch, report that fumes rising from the ground enveloped the Pythia, who offered her answer in a trance-like, sometimes frenzied state. In the 1990s, a team of scientists discovered an underground spring running below Delphi. It carried important traces of ethylene, a gas that smells slightly sweet -- matching Plutarch's description of the fumes as heavily perfumed -- and puts the user in states swinging from the beatific to bizarre.
This brings us back to 480 BCE. Did the Greeks allow themselves to be guided by a glue sniffer? Not at all. Consider both her answer to the supplicants and their response. The oracle announced: "All shall be taken by the enemy," but added: "A wall of wood which alone shall survive the foe ... shall serve you and your children ... Turn your back in retreat; on another day you shall face them."
Back in Athens, there was a welter of interpretations. Many thought the Pythia meant the thorn bushes encircling the Acropolis would save the city. An outspoken Athenian, Themistocles, disagreed: the wooden wall meant Athen's naval fleet. The city's survival lay not in the city, but in the ingenuity of its people: Athens at sea, in its hundreds of triremes, alone could defeat Xerxes. A few months later, Themistocles' interpretation was borne out: Athens defeated the Persian fleet off the coast of Salamis.
Athens survived long enough to be pestered, later in the century, by the philosopher Socrates. Delphi famously declared that Socrates was the wisest of all men. Convinced the oracle was wrong, Socrates tried to find a wiser man. But when he questioned his fellow Athenians, they revealed themselves to be wise only in their own fields. Beyond that they were ignorant. This ignorance, however, was not blissful, but tragic: these men did not know that they did not know.
Socrates concluded he was indeed the wisest man, if only because he knew he was ignorant. Then as now, this is the cardinal rule of intelligence analysis: we take from it what we bring to it: our fears and hopes, selfish biases and selfless concerns, our insight and blindness.
