In Poseidon’s Realm: Underwater Archaeology in the Mediterranean
More than two thousand years ago, Greek and Roman professional divers, including both men and women, were diving to depths of more than 100 feet to recover art objects and other treasures from shipwreck sites. Their modern successors have continued to explore the floor of the Mediterranean Sea for sunken ships, cargoes, harbors and other submerged structures. Helmeted sponge divers made the most extraordinary discovery of all in 1900 at Antikythera, where they recovered the remains of an astronomical computer of bronze gears dating to the first century BC. The world’s first scientific underwater excavation was conducted on the Mediterranean site of Cape Gelidonya in 1960, where George Bass led an archaeological expedition to a Bronze Age wreck. Marine archaeologists now use scuba-gear, robotic devices such as ROVs, or remote operated vehicles, bathyscaphs, sidescan sonar, magnetometers and other equipment, but many classical underwater sites still remain to be located, mapped, and excavated. This lecture provides an overview of this important field, illustrates many of the most important art works recovered from the sea, including the famous bronze god from Artemision, and shows current technology in use during the Persian Wars Shipwreck Survey, in which John Hale participated as an archaeologist.The Delphic Oracle: Modern Science Examines An Ancient Mystery
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 an 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.
