Ancient Greek and Roman authors stated that the Apollo’s sacred oracle at Delphi in central Greece was located at the site of unusual geological features and phenomena: a chasm or fissure in the rock; an emission of sweet-smelling vapor or gas; and a sacred spring.  The priestess who pronounced the oracles, known as the Pythia, sat on a tall tripod above the fissure where she could inhale the vapor, thus triggering a prophetic trance in which she could serve as a medium for the prophetic oracles of the god Apollo.  So great was the influence of the woman’s words that scarcely a colony was founded or a war undertaken in Greece for over a millennium without the sanction of the Delphic Oracle.  Famous figures from Oedipus and Agamemnon to Alexander the Great and various Roman emperors consulted the shrine. During the 20th century, most scholars adopted a skeptical attitude towards the ancient traditions about Delphi, denying that there had ever been a fissure or a gaseous emission in the crypt of the temple.  However, in 1995 an interdisciplinary team was created to study not only the archaeology of Delphi, but also the evidence from geology, chemistry, and toxicology that related to the oracle.  The results of the research vindicated the ancient sources.  Our team has gone on to study Greek oracle sites elsewhere in the Aegean and Asia Minor, where we have found similar geological features.

Dr. John Hale, University of  Louisville, Kentucky, specializes in underwater archaeology, classical Greece and Rome, Viking shipbuilding technology, and the Delphic Oracle. He has taught archaeology at the University of Louisville since 1983. He performed fieldwork on the DANAOS Project in eastern Mediterranean, studying deep submergence survey of ancient sea-routes between Crete and Egypt, from 2007-2009. From 2003-2006, he  participated in the Persian Wars Shipwreck Survey in Greece (Aegean Sea). Other projects include the Phoenician Harbors Project at coastal sites in Portugal; Testing of Roman concrete structures in Spain and Italy for Mortar Dating Project with Abo Akademi, Finland; Geological and archaeological investigations at the site of the Delphic Oracle, Greece:  Field director at excavations of the Roman villa and early medieval basilica of Torre de Palma, Portugal; and Field director for salvage archaeology and Cultural Resource Management projects on sites in the Ohio River Valley.
